One-way throttle valve and lifting oil cylinder structure

The invention discloses a one-way throttle valve and a lifting oil cylinder structure. The one-way throttle valve comprises a valve body; a first hole and a second hole which are communicated with each other are formed in the axial direction of the valve body, the diameter of the first hole is larger than that of the second hole, a plurality of radial holes are formed in the outer side of the valve body, and the radial holes are all communicated with the first hole. According to the one-way throttle valve, only one valve body is arranged, various holes are formed in the valve body, the functions of one-way throttling and one-way control over the action speed of the hydraulic oil cylinder can be achieved, compared with the prior art, only one valve body is arranged, various parts are reduced, and the structure is very simple.
