Description

Technical Field

[0001] The utility model relates to the technical field of lifters, in particular to a slider structure of a screw lifter. Background Technique

[0002] The screw lifting body is a common linear motion device, usually used in industrial automation and mechanical equipment to achieve vertical lifting motion. It consists of a screw rod, a nut, a motor and related supporting and guiding components. The screw lifting body can usually be customized according to specific application requirements, for example, it can be selected according to parameters such as load-bearing capacity, lifting speed, and lifting height. It is widely used in various fields, such as material transportation on industrial production lines, automobile maintenance equipment, medical equipment, office furniture, etc., to achieve the lifting or position adjustment of objects.

[0003] Currently, a slider structure is usually installed inside the screw lifter to improve the stability of the lifter during movement. However, the slider generally slides back and forth on the surface of the sliding rod. After a long time, due to the long-term contact between the slider and the sliding rod contact surface, problems such as insufficient lubrication and noise will occur. Moreover, when the lubrication is insufficient, the staff needs to manually disassemble the lifter for oil injection work, thus increasing the use cost and reducing the work efficiency. Content of the Utility Model

[0004] The purpose of the utility model is to provide a slider structure of a screw lifter to solve the problems raised in the above background technique.
