Abstract
Description
Technical Field
[0001] This utility model relates to the field of window opener chain technology, and in particular to a U-shaped bent plate chain. Background Technology
[0002] A window opener chain is a moving component used in electric window openers. Electric window openers are a new type of door and window machinery, suitable for raising and fixing indoor and outdoor sunshade roller blinds and other products such as aluminum alloy doors and windows, PVC doors and windows, and wooden doors. They are characterized by their small size, light weight, and easy installation. The chain is a key component in the window opener, and ensuring 10,000 uninterrupted opening and closing cycles is a core requirement. Due to its special nature, the reliability and service life requirements for window opener chains are far greater than those for industrial chains. A highly reliable window opener chain is a crucial component for ensuring the long-term effective operation of the window opener and preventing jamming or damage. With continuous technological development, the requirements for window opener chains are also increasing.
[0003] Existing window opener chains have certain drawbacks in use. First, existing window opener chains are all bent at 45 or 90 degrees. Due to the relatively small contact surface, the chain is prone to deformation after being squeezed by gravity, which makes the chain easy to shake and bend when it is pushed out, which brings certain adverse effects to the actual use process. To this end, we propose a U-shaped bent plate chain. Utility Model Content
[0004] Technical problem solved: In view of the shortcomings of the existing technology, this utility model provides a U-shaped bent plate chain. The chain plate is changed to a U-shaped bent plate, which improves the aesthetics, support strength and running stability of the chain. When in use, the chain plate bears the force by the middle of the bend, and the contact area is large. The chain will not shake or bend when pushed out, and the stability is better. It can effectively solve the problems in the background technology.
