Title:
NEW DAMPER FOR SLIDING DOOR AND WINDOW
Document Type and Number:
WIPO Patent Application WO/2024/001671
Kind Code:
A1
Abstract:
Disclosed in the present application is a new damper for a sliding door and window. No guide groove needs to be provided on a damper housing, other high-strength and high-performance materials apart from sheet metal parts can be used as housing materials to implement the upgrading of the structure and materials of the housing, and the overall structure has high strength and excellent stability, such that structural deformation of the housing in the case of long-term use is avoided; the housing does not need to be separated into two halves for processing, and can be directly processed as one piece during production, such that the precision of the overall structure is easier to control, the assembly process of the damper is also greatly simplified, and the phenomenon of scrapping is not prone to occurring during assembly; and a first limiting member and a second limiting member are arranged inside the housing, such that a shift block is prevented from moving back under an acting force of a tension spring, and no vertical corner section of the guide groove needs to be configured, thereby solving technical problems such as it being difficult to shift the shift block inwards again due to a corner section being too close to vertical.
