Description

Technical Field

[0001] The utility model relates to the field of hardware accessories, in particular to an adjustable power-assisting structure for a transmission and a lifting and sliding door and window system. Background Art

[0002] The existing lifting and sliding door and window system uses the principle of lever theory to drive the actuator by rotating the handle, and then drives the pulley mechanism set at the bottom of the window sash to lift or lower the window sash, thereby achieving the lifting or lowering of the window sash.

[0003] In order to achieve a cushioning effect during the descent of the window sash and a boosting effect during the lifting process, a metal spring or a gas spring is generally used to directly connect to the actuator to improve the feel of the handle during operation. However, traditional single metal springs and gas springs cannot adapt to window sashes of different weight specifications, which often causes the handle to feel too heavy during operation.

[0004] Chinese patent CN219931937U discloses an adjustable buffer booster for lifting and sliding door transmission, which uses a gear rack meshing with each other to achieve transmission, uses a screwing tool to drive the active part to rotate, and through the linkage of the gear rack structure, drives the driven part to move linearly, and simultaneously drives the moving part to overcome the obstruction of the limit part and compress the elastic element, so as to adjust the size of the elastic element's thrust to adapt to door leaves of different weight specifications, which is conducive to improving the feel when operating the handle. However, this solution uses a rack as the driven part, and the rack is set beside the gear. In order to make the central axis of the rack coaxial with the central axis of the moving part, the overall structure needs to be made wider. Utility Model Content
