Technical Field

[0001] The utility model relates to the technical field of hydraulic jacks, in particular to a hydraulic jack with a safety valve and high stability. Background Technique

[0002] A jack refers to a light lifting device that uses a rigid lifting member as a working device and jacks up a heavy object within a small stroke through a top support or a bottom support claw. Jacks are mainly used in factories, mines, transportation and other departments for vehicle repair and other lifting and supporting work. Their structures are light, strong, flexible and reliable, and can be carried and operated by one person.

[0003] In order to control the flow and pressure of hydraulic oil, the existing hydraulic jacks are all equipped with safety valves, so that the jacks can be used safely. However, in order to ensure the portability of the common hydraulic jacks on the market, the volume of the base in contact with the ground is mostly designed to be small. However, this will result in a small contact area between the hydraulic jack and the ground, resulting in low stability and a risk of tipping. In view of the above situation, technical innovation is carried out on the basis of the existing hydraulic jacks with safety valves. Content of the Utility Model
