Description

Technical Field

[0001] The utility model relates to the field of door locks, and more specifically, to a multifunctional handle door lock structure. Background Art

[0002] At present, the handle locks on the market generally can only be used in combination with each other when their specifications and dimensions correspond, and cannot be used in combination with handle locks of other specifications. During installation, if the holes on the door are drilled in the wrong positions, it is necessary to re-drill the holes, which is very troublesome. Therefore, there are still defects in the handle locks on the market at present. The existing multifunctional fear handle universal lock has a complex structure and is not easy to install. For the existing handle door lock with adjustable hole distance, the structure is complex and the assembly is inconvenient. Therefore, a multifunctional handle door lock with adjustable hole distance is needed to solve these problems.

[0003] The utility model with the authorization announcement number CN208380286 provides a multifunctional handle door lock with adjustable hole distance, which includes a door lock panel and a handle assembled on the door lock panel. The door lock panel includes a first panel and a second panel, and also includes a first connecting plate and a second connecting plate. The first connecting plate is fixedly assembled with the first panel by screws, and the second connecting plate is welded and fixed with the second panel as a whole. It also includes an adjusting rod. The first connecting plate and the second connecting plate are both provided with sliding adjustment grooves for the adjusting rod to slide. The sliding adjustment groove of the first connecting plate is connected with the sliding adjustment groove of the second connecting plate through the adjusting rod. In this product, the second connecting plate and the second panel are fixed by welding. During assembly, only the first adjusting plate and the first panel need to be installed by screws, and the assembly is convenient. Even if the hole positions on the door panel are incorrect, the assembly can be achieved by adjusting the position of the adjusting rod in the adjustment groove without re-drilling the holes. The structure is simple and very practical.
