Description

Technical Field

[0001] The utility model relates to the technical field of door handles, in particular to a hidden handle damping and self-positioning structure. Background Art

[0002] At present, there are many types and shapes of traditional old-style handles widely used in various industries such as entrance doors, interior doors, cabinet doors, etc. in the market. Most of them are handles with the handle body and handle body base protruding from the installation surface, which takes up a large space and is easy to bump into people. However, there are very few hidden handles that make the protruding handles roughly flush with the installation surface, or achieve a hidden or concealed appearance.

[0003] With the popularization and application of fully automatic electronic smart locks, especially in the use scenarios equipped with such smart automatic locks or door openers, intelligent automatic unlocking or door opening is realized, and the situations of unlocking or door opening by mechanical keys or handles are greatly reduced, and are only used occasionally or in emergency. Therefore, the market requirements for the appearance of these old-fashioned universal handles have also been greatly improved accordingly.

[0004] Previously, there have been sporadic applications and applications for hidden handle patents, such as a buffer hidden handle disclosed in Chinese patent document CN209413459U, and a hidden handle and bathroom cabinet disclosed in Chinese patent document CN214117782U. However, they are mainly used in cabinet doors, and the structure is too simple, and they cannot match the structural and functional requirements of inserting a key into a mechanical lock core for emergency unlocking, and the user experience is not good. Among them, a buffer hidden handle disclosed in Chinese patent document CN209413459U is a simple side-rotating structure superimposed with a mechanical gear damper, but it is a non-self-elastic, self-locking damping, self-positioning structure handle, that is, the structure is rigid and simple, the appearance is poor, the function is incomplete, the user experience is not good, and so on, it is not the best technical solution.
