Description

Technical Field

[0001] The utility model belongs to the technical field of rotating feet, in particular to a three-section rotating foot. Background Art

[0002] A two-post lift is a common lifting equipment. Through the collaboration of the hydraulic system and the control system, the lifting platform can be moved up and down. It is widely used in vehicle inspection and maintenance, logistics and other fields. The rotating support foot is located at the top of the lift arm, and its main function is to support the load in the upper step frame. The existing car lift rotating support foot is generally a two-section rotating support foot, which consists of a support base, a threaded rod and a support seat. The connection between the support seat and the threaded rod can adjust the height of the entire support foot, so as to adjust the load in the upper step frame to a horizontal state.

[0003] Since the two-section rotating support cannot meet the use requirements when adjusted to the maximum height, the support seat height is adjusted by lifting the load-bearing rotating support base and threaded rod, and then installing the support foot height increasing sleeve on the support base. If the load on the support seat is heavy, it is time-consuming and laborious to lift the load-bearing rotating support base and threaded rod and then install the height increasing sleeve. Secondly, the target height cannot be controlled. For this reason, a three-section rotating support is proposed here. Utility Model Content
