Top disk lockable hydraulic jack with safety valve

Abstract

The invention discloses a top disk lockable hydraulic jack with a safety valve. The hydraulic jack comprises a jack body and a top disk body. The top disk body is fixedly connected to the top of the jack body. The side surface of the top disk body is fixedly connected with one ends of guide rods. The other ends of the guide rods are movably connected with the inner wall of a round tube. The surfaces of the guide rods are movably sleeved with two movable rods. The two movable rods are located on the two sides of the top disk body correspondingly. The sides, far away from the top disk body, of the movable rods are in lap joint with the inner wall of the round tube. The tops of the movable rods are fixedly connected with movable blocks. Internal threaded pipes are inlaid in the movable rods and located below the guide rods. The top disk lockable hydraulic jack is provided with the guide rods, the round tube, the movable blocks, threaded pipes and antiskid pads, and the problems that a topdisk of an existing common hydraulic jack with a safety valve and a heavy weight can be fixed relatively and is low in safety is solved.

Description

technical field [0001] The invention relates to the technical field of jacks, in particular to a hydraulic jack with a lockable top plate and a safety valve. Background technique [0002] A jack refers to a light and small lifting device that uses a rigid lifting piece as a working device, and lifts heavy objects within a small stroke through the top bracket or bottom claw. The jack is mainly used in factories, mines, transportation and other departments as vehicle repair and other Lifting, supporting and other work, its structure is light and firm, flexible and reliable, and can be carried and operated by one person. The safety valve hydraulic jack is improved on the basis of the jack. In order to consider safety during work, the hydraulic valve is mainly Used to lock the hydraulic pressure, the top plate is the top bracket, which directly contacts the lifted weight. [0003] The current common hydraulic jack with a safety valve is relatively unfixed between the top plate ...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to overcome the deficiencies of the prior art and provide a hydraulic jack with a safety valve that can be locked on the top plate, which solves the problem of the relative relationship between the top plate and the heavy object of the common hydraulic jack with a safety valve. Unfixed, leading to less secure issues
