Problems solved by technology

[0002] Traditional jacks have a strong grip on rough ground, but when supporting heavy objects on smooth ground, they often slip due to insufficient friction or incorrect fulcrums, so that they cannot provide stable support, and problems such as jack overturning occur. , and for some grounds with insufficient ground hardness, the ground is easily damaged due to too much impulse during the use of the jack

Embodiment Construction

[0012] Specific embodiments of the present invention are described below in conjunction with accompanying drawing:

[0013] Such as figure 1 As shown, a hydraulic jack includes a jack body, and the jack body includes a base 6, an oil pipe 3 and a shaft seat 2 on the base, a core tube 1 protruding from the shaft seat 2 and a cylinder on one side of the jack body The lifting adjustment device 4 also includes an upside-down disc-shaped adsorption part 5, which is located at the bottom of the base 6. The lifting adjustment device 4 is similar in structure to the pedal of a bicycle, which is convenient for operation and adjustment of the jack and saves effort. And convenient.

[0014] The disc-shaped absorbing part 5 is movably connected with the base 6, and it is possible to choose whether to add the disc-shaped absorbing part 5 according to the use environment.

[0015] Such as figure 2 As shown, the bottom surface of the base is also provided with a number of chain-shaped pr...

Abstract

The invention provides a hydraulic jack. The hydraulic jack comprises a jack body. The jack body comprises a reversely-buckled disc-shaped adsorption piece which is located at the bottom of a base of the jack body, and the disc-shaped adsorption piece is movably connected with the base. According to the hydraulic jack, the reversely-buckled disc-shaped adsorption piece is additionally arranged at the bottom of the base of the jack body so that the hydraulic jack can be better adsorbed onto the ground and particularly onto the ground with small friction, the disc-shaped adsorption piece has a more stable supporting function, and using is safer.

Description

technical field [0001] The invention relates to a jack, in particular to a hydraulic jack. Background technique [0002] Traditional jacks have a strong grip on rough ground, but when supporting heavy objects on smooth ground, they often slip due to insufficient friction or incorrect fulcrums, so that they cannot provide stable support, and problems such as jack overturning occur. , and for some grounds with insufficient ground hardness, the ground is easily damaged due to too much impulse during the use of the jack. [0003] Therefore, it is necessary to invent a safe and practical reinforced jack that can be adapted to smooth ground and rough ground to solve the above problems. Contents of the invention [0004] The invention provides a hydraulic jack to solve the problems in the prior art. [0005] In order to solve the above-mentioned technical problems, the technical solution adopted in the present invention is: a hydraulic jack, comprising a jack body, said jack bo...
