Description

Technical Field

[0001] The utility model relates to the technical field of lifting doors, in particular to an automatic balancing lifting door. Background Art

[0002] Manual lift doors are heavy and require a lot of strength to lift. With the advancement of automation technology, the existing pneumatic, electric and mechanical power-assisted mechanisms can realize the automatic lifting function of doors. However, pneumatic and electric power-assisted lift doors are expensive and complex in structure. The lifting action requires key operation and waiting for pneumatic and electric responses, which results in a poor user experience.

[0003] The common mechanical power-assist structure consists of a tension spring, a steel wire rope and a pulley, but its disadvantages are that the tension of the tension spring is nonlinear, fluctuating and causing abnormal noises; the steel wire rope is easily broken due to repeated rolling and friction; and it must be lifted to the highest point and fixed by a positioning mechanism. Common positioning mechanisms are positioning beads or magnets, which are prone to failure. If they fail, there is a risk of the door falling off, posing a huge safety hazard; the structure cannot hover at any position.

[0004] In order to solve the above-mentioned shortcomings, the utility model discloses an automatic balancing lifting door. Utility Model Content
