Embodiment Construction

[0017] The present invention will be further described in detail below through the specific examples, the following examples are only descriptive, not restrictive, and cannot limit the protection scope of the present invention with this.

[0018] Such as Figure 1-2 As shown, a hydraulic jack with a safety valve whose top plate can be locked includes a jack body 1 and a top plate body 2, the top plate body 2 is fixedly connected to the top of the jack body 1, and the side surface of the top plate body 2 is connected to One end of the guide rod 3 is fixedly connected. The guide rod 3 guides the movable rod 5 so that the movable rod 5 can move left and right. The rod 3 and the surface of the guide rod 3 are movably socketed with a movable rod 5, and the movable rod 5 plays a connecting role and is used to connect the movable block 6, and the number of the movable rod 5 is two, and the two movable rods 5 are respectively located on the top plate The two sides of the body 2, and ...

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 ...
