Description

Technical Field

[0001] This utility model relates to the field of jack technology, specifically an anti-tilting hydraulic jack. Background Technology

[0002] A jack is a small, lightweight lifting device that uses a rigid lifting component as its working device to lift heavy objects within a short stroke through a top support or bottom claw. Jacks are mainly used in factories, mines, and transportation sectors for vehicle repair and other lifting and supporting work. They are lightweight, sturdy, flexible, and reliable, and can be carried and operated by one person. Hydraulic jacks, while primarily used in factories, mines, and transportation sectors for vehicle repair and other lifting and supporting work, are prone to tilting when working on sloping ground or when subjected to horizontal forces due to their smaller contact area with the ground.

[0003] An existing anti-tilt hydraulic jack with application number 202011220969.1 includes a base and a jack body. By setting an anti-tilt plate on the outside of the base, the open anti-tilt plate can solve the problem of insufficient bottom support force of traditional hydraulic jacks on special fixed surfaces. The angle of the anti-tilt plate is adjustable to adapt to various uneven ground, making the device more practical. During the use of the jack body, it always maintains sufficient support force to prevent it from tilting and protect the safety of surrounding users. However, the anti-tilt bracket is large in size, inconvenient to carry, and the bracket adjustment operation is inconvenient. Utility Model Content
