AI Technical Summary

Technical Problem

The exposed rope pulleys of existing portable lifters cause foreign objects to become entangled and wear severely. The segmented rope guide mechanism has gaps that result in high resistance, making it easy for the rope to get stuck or cut. Furthermore, the locking mechanism is prone to misoperation.

Method used

A portable lifting device with a protective cover was designed. It adopts a dual locking mechanism with horizontal and vertical locking, combined with an unlocking key structure, to ensure a reliable connection between the protective cover and the lifting device, and to form a closed rope channel inside to reduce wear.

Benefits of technology

It improves the safety and reliability of the lifting device, prevents foreign objects from getting tangled in the rope pulley, reduces wear on the nylon rope, and makes the unlocking operation convenient and reliable, avoiding misoperation.

Abstract

The utility model provides a portable lifter with protective cover to improve the reliability of lifter. Including lifter integration and protective cover integration, and horizontal locking assembly and vertical locking assembly, wherein: protective cover integration is assembled with the rotation of lifter integration through the rotation shaft, and protective cover integration rotates to cover lifter integration, and then is locked with lifter integration after displacement a certain distance along the vertical direction. Horizontal locking assembly locks protective cover integration in horizontal direction, and vertical locking assembly locks protective cover integration in vertical direction, and horizontal direction and vertical direction are perpendicular to each other. Corresponding vertical locking key is also provided with unlocking key, and the unlocking operation of unlocking key is very convenient, and downward pressing can release vertical locking, and further pressing can release horizontal locking, so that the operation is convenient, and can prevent misoperation well, and improve the safety of lifter.
