Description

Door lock handle assembly

Technical Field

The application belongs to hardware furniture accessory technical field, specifically speaking relates to a door lock handle subassembly.

Background

The handle door lock is a common lockset applied to household doors, and is widely applied to the furniture industry. By adopting the handle door lock, a user can not only realize the unlocking and locking functions from the inside of the door, but also realize the unlocking and locking functions from the outside of the door. The handle door lock generally comprises an outer handle and an inner handle and is connected through a linkage rod.

The inner handle and the outer handle are realized through a linkage rod such as a linkage rod. In the prior art, the trace is mounted and fixed to the handle by means of screws. However, this fixing manner by the screw has various drawbacks such as the need to manually screw the screw by means of a tool, so that the installation efficiency is low, and time and effort are wasted; for another example, the use of screw fastening leads to a complicated structure of the entire inner handle assembly, which undoubtedly increases the production cost; in addition, this results in poor applicability of the product, such as mounting only a handle of a specific size.

Accordingly, there is a need in the art for a handle assembly that overcomes the above-described deficiencies of the prior art.
