Description
Technical Field
[0001] This utility model relates to the field of door handle technology, and in particular to a retractable door handle for door locks. Background Technology
[0002] Door handles serve to assist in opening and closing doors. Currently, most door handles protrude from one side of the door. When a person moves, especially when running, their body is likely to bump into the protruding door handle and cause injury, posing a significant danger. In addition, for current combination lock doors, exposed door handles appear rather obtrusive and affect the overall aesthetics of the door.
[0003] To address the aforementioned issues, existing patent (CN221568155U) discloses a retractable door handle, comprising a door panel. A storage groove is provided on the right side of the front of the door panel, and a handle support is rotatably connected to the inner wall of the storage groove. A door handle is hinged to the bottom of the front of the handle support. By hinged the handle support to the handle holder, the handle holder can be pressed into the inner wall of the storage groove when the door handle is not in use, thus preventing the door handle from protruding from one side of the door panel. This avoids the problem of a person's body easily bumping into the protruding door handle when moving, especially when running, which could lead to injury. Furthermore, by incorporating an adsorption groove and a magnetic block, the handle support is fixed in place by the magnetic force of the magnetic block adsorbing it onto the inner wall of the adsorption groove when it is upright, preventing instability when the handle support rotates.
[0004] However, in the aforementioned existing technologies, the door handle is hidden by rotating, which easily causes external dust to adhere directly to the surface of the door handle and the storage groove, requiring users to clean the door handle regularly, making it inconvenient to use.
