Description

Technical Field

[0001] The utility model relates to the technical field of handles, in particular to a flat and swing-open integrated hidden handle. Background Art

[0002] At present, the traditional old-style handles widely used in various industries such as entrance doors, interior doors, and cabinet doors are available in various types and shapes on the market. Most of them have handle bodies and handle body bases protruding from the installation surface, which takes up a large space and is easy to bump into people. There are also a few handles that are foldable, which makes the door handle smaller in size due to the folding effect, but its aesthetics is affected to a certain extent. 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 situation of unlocking or opening the door by mechanical keys or handle bodies is greatly reduced, and it is only used occasionally or in emergency unlocking.

[0003] Therefore, the market's requirements for the appearance of these old universal handles have also increased significantly. After the emergence of the new trend of hidden handles on car doors, the demand for the overall flattening of the protruding handles, and the invisible or hidden effect, has become increasingly strong. Previously, there have been sporadic applications and applications for hidden handle patents.

[0004] For example, Chinese utility model patent CN209413459U discloses a buffer hidden handle and Chinese utility model patent CN214117782U discloses a hidden handle and bathroom cabinet, but they are mainly used in cabinet doors and have too simple structures to meet the requirements of various types of entrance doors, interior doors and other door industries.

[0005] Another example is the hidden handle disclosed in Chinese utility model patent CN213330412U, in which the handle panel is flush with the door leaf surface, but the handle panel is immobile, and there is a large side gap between the main side of the handle panel and the door leaf to prevent fingers from inserting into the sliding door, creating a large pothole effect on the appearance, and cannot meet the structural and functional requirements of inserting a key into a mechanical lock core for emergency unlocking, that is, the structure is rigid and simple, the appearance is poor, the functions are incomplete, and the application range is narrow.
