Description

Technical Field

[0001] The utility model relates to the technical field of lifting windows, in particular to a worm gear lifting device for lifting windows. Background Art

[0002] Lifting doors and windows are widely used because they do not occupy indoor and outdoor space, are flexible to open, increase indoor lighting, can replace guardrails when the windows are open, and improve the overall appearance of the building. Lifting doors and windows on the market usually use single motors and dual motors. Among them, the single-motor lifting window system uses a planetary reducer in its structure, which makes the system run loudly and requires a counterweight, resulting in an unsightly profile design; while the dual-motor lifting window system uses two sets of motors, which easily causes the left and right lifting to be out of sync, is expensive, and the chain-type lifting system has no mechanical self-locking. When there is a problem with the motor brake, accidents are likely to occur. Utility Model Content
