HOLLOW POSITIONING NUT STRUCTURE OF SLIDE RAIL BRACKET

The present disclosure relates to a hollow positioning nut structure of a slide rail bracket, and more particularly, to a structure enabling an auxiliary bracket to correspond to any longitudinal rod body by using a coupling device.

In treatment of various affairs nowadays, networks are used for transmitting task applications. Network signals can be supplied to users for use via servers. The future artificial intelligence (AI) also needs to rely on the servers to supply actions.

However, engaging structures between the servers and cabinets are evolved from securing manners to slide rail manners to provide more convenient use. Specifications of corresponding holes of the cabinets include square holes, circular holes and threaded holes to correspond to the servers, and three corresponding holes in each group are engaged to the slide rail.

To cater for the specifications of the cabinets, an applicant files a China Application No. 2018202079030 titled “THREE-IN-ONE ASSEMBLED GUIDE RAIL STRUCTURE”. As shown in FIG. 1A, FIG. 1B and FIG. 1C, quick detachable slide rail structure is presented in this application, wherein the cabinet pillar 10 has three hole specifications, namely a square hole 101, a circular hole 102 and a threaded hole 103. To fit to the holes of the cabinet pillar 10, an end portion of the slide rail 11 is provided with a pressing member 110 and a guide thread insert 12. Three corresponding holes in each group are engaged to the slide rail of the cabinet, thus the pressing member 110 respectively corresponds to the first hole and the third hole, and the guide thread insert 12 corresponds to the second hole. The pressing member 110 includes a bolt 1100, an elastic element 1101, and a first thread insert 1102. The first thread insert 1102 is formed into cylindrical bodies laminated in different diameters to correspond to the square hole 101, the circular hole 102 and the threaded hole 103 of the cabinet pillar 10. The guide thread insert 12 ensures the engagement between the slide rail 11 and the cabinet pillar 10 to be more stable, and more accurately provides quick detachable pieces for positioning and locking.

However, the guide thread insert 12 does not fit to the specification of the threaded hole 103 of the cabinet pillar 10, and thus it is required to dismantle the guide thread insert 12 before the installation, which may reduce engagement stability and accuracy of the slide rail 11.

Because the existing guide thread insert 12 does not fit to the specification of the threaded hole 103 of the cabinet pillar 10, the applicant provides a hollow positioning nut structure of a slide rail bracket. The guide thread insert 12 is substituted with a hollow positioning nut, which can fit to the square hole 101, the circular hole 102 and the threaded hole 103 of the cabinet pillar 10, and thus achieving a better applicability.

A major objective of the present disclosure resides in using a hollow positioning nut to fit to fixing holes and grooves of cabinet pillars of different specifications.

To achieve the above objective , the hollow positioning nut of the present disclosure includes: a tubular pillar piece, a resisting piece, a spiral portion, and a convex portion. The tubular pillar piece is a hollow tubular body, extends to the resisting piece in a side of an outer ring of the tubular pillar piece, and a spiral portion is formed around an inner ring of the tubular pillar piece. The resisting piece is a tabular body, and extends to an end in a side of the tubular pillar piece. The spiral portion is an adapter, and is formed on an inner edge wall surface of the tubular pillar piece.

The convex portion is a retaining body, and is formed on another end opposite to the tubular pillar piece. When the hollow positioning nut is combined with a stud and rotates toward a side, the resisting piece resists and positions a wall surface, such that the stud clockwise rotates and the hollow positioning nut fits to perforations of a variety of cabinet pillars.

The resisting piece of the hollow positioning nut extends to two sides of the outer ring of the tubular pillar piece.

The tubular pillar piece of the hollow positioning nut may have one tangent plane.

The tubular pillar piece of the hollow positioning nut may have two tangent planes.

The tubular pillar piece of the hollow positioning nut may have a plurality of tangent planes.

As shown in FIG. 2, FIG. 3 and FIG. 9, the present disclosure provides a hollow positioning nut structure of a slide rail bracket. The slide rail bracket 3 includes a hollow positioning nut 20, an engaging member 30, a first pressing member 31, a second pressing member 32, a resisting plate 33, and a stud 34. The hollow positioning nut 20 includes: a tubular pillar piece 200, a resisting piece 201, a spiral portion 202, and a convex portion 203. The tubular pillar piece 200 is a hollow tubular body, extends to the resisting piece 201 in a side of an outer ring of the tubular pillar piece, and the spiral portion 202 is formed around an inner ring of the tubular pillar piece 200. The tubular pillar piece 200 corresponds to a first perforation 330 of the resisting plate 33. The resisting piece 201 is a tabular body, and extends to an end in a side of the tubular pillar piece 200. The spiral portion 202 is an adapter, and is formed on an inner edge wall surface of the tubular pillar piece 200. The convex portion 203 is a retaining body, is formed on another end opposite to the tubular pillar piece 200, and corresponds to a first spring piece 204. When the hollow positioning nut 20 is combined with the stud 34 and rotates toward a side, the resisting piece 201 resists and positions a retaining wall 333, such that the stud 34 clockwise rotates and the hollow positioning nut 20 fits to perforations of a variety of cabinet pillars 4.

The engaging member 30 is a bent body. On a longitudinal wall surface there is provided a first retaining hole 300, a second retaining hole 301, and a third retaining hole 302. A side of the first retaining hole 300 corresponds to the first spring piece 204, the hollow positioning nut 20 and the first perforation 330 of the resisting plate 33, and the stud 34 penetrates through each component to secure the first retaining hole 300.

The first pressing member 31 includes a first bolt 310, a second spring piece 311, and a first cap member 312. One end of the first bolt 310 forms a first bolt portion 3100 to correspond to the third retaining hole 302 of the engaging member 30, whereas the other end of the first bolt 310 penetrates through the second spring piece 311 and the first cap member 312, and then corresponds to a third perforation 332 of the resisting plate 33.

The second pressing member 32 includes a second bolt 320, a third spring piece 321, and a second cap member 322. One end of the second bolt 320 forms a second bolt portion 3200 to correspond to the second retaining hole 301 of the engaging member 30, whereas the other end of the second bolt 320 penetrates through the third spring piece 321 and the second cap member 322, and then corresponds to a second perforation 331 of the resisting plate 33.

The resisting plate 33 is a bent body, a retaining wall 333 is formed at an end of the bent body, whereas the first perforation 330, the second perforation 331 and the third perforation 332 are formed on a vertically bent wall surface of the retaining wall 333. One end of the first perforation 330 is correspondingly penetrated by the hollow positioning nut 20, whereas the other end of the first perforation 330 is penetrated by the stud 34 and is corresponding to the hollow positioning nut 20. The second perforation 331 is corresponding to the second pressing member 32, and the third perforation 332 is corresponding to the first pressing member 31.

As a fastener, the stud 34 penetrates through the first perforation 330 of the resisting plate 33, the hollow positioning nut 20 and the first spring piece 204, and is correspondingly bolted to the first retaining hole 300. By means of the hollow positioning nut 20, the first pressing member 31 and the second pressing member 32, one end of the slide rail bracket 3 is provided with an elastic body to correspond to the cabinet pillars 4 having different corresponding holes.

For another example, as shown in FIG. 2, FIG. 4 and FIG. 5A˜FIG. 5D, the hollow positioning nut 20 forms a resisting piece 201 around a ring of the tubular pillar piece 200. The tubular pillar piece 200 corresponds to the stud 34. A coaxial rotation may occur when stud 34 rotates toward a side. A side edge or a vertical angle of the resisting piece 201 oppositely resists against the retaining wall 333 of the resisting plate 33, such that the stud 34 is continuously secured to the other end.

Nevertheless, a resisting piece 201 of the hollow positioning nut 20 may be formed around a ring of the tubular pillar piece 200, or two opposite resisting pieces 201 may be formed around the ring of the tubular pillar piece 200.

As shown in FIG. 5B˜FIG. 5D, to achieve a position limiting function, the resisting piece 201 may be canceled. One or more tangent planes may be formed on the tubular pillar piece 200, for example, the tubular pillar piece 200 having one tangent plane, the tubular pillar piece 200 having two tangent planes, and the tubular pillar piece 200 having a plurality of tangent planes. More diversified embodiments are provided, and the tubular pillar piece 200 corresponds to the first perforation 330 of the resisting plate 33, whereas the first perforation 330 has equivalent shapes based on shapes of the tubular pillar piece 200 to the mutually resisting position limiting function.

As shown in FIG. 3, FIG. 6, FIG. 7, FIG. 8 and FIG. 9, which are schematic diagrams of engaging a cabinet pillar 4 to the slide rail bracket 3, when the slide rail bracket 3 corresponds to the cabinet pillar 4, in the cabinet pillar 4, two threaded holes 40 are first sleeved at one end of the first bolt 310 and one end of the second bolt 320, next, the hollow positioning nut 20, the first cap member 312 and the second cap member 322 are simultaneously squeezed to one end, such that the cabinet pillar 4 and the resisting plate 33 form gapless parallel fitting, and then the stud 34 penetrates through either one of the threaded holes 40 of the cabinet pillar 4 and the hollow positioning nut 20 to correspond to the first retaining hole 300 of the engaging member 30.

Nevertheless, this is an specification embodiment of the threaded hole 40 corresponding to the cabinet pillar 4. Furthermore, embodiments corresponding to the cabinet pillars 4 forming square holes or circular hole may be provided.
