Abstract

A door lock with an adjustable distance between a handle and a key hole center is mainly composed of a front panel assembly 1, a rear panel assembly 1, a lock body assembly 2 and a lock cylinder assembly 3, and an adjustable key hole module 1-1 capable of moving up and down in a notch is arranged in the front panel assembly. The bottom plate 1-2 is provided with screw holes 1-2-2 used for displaying numerical values 1-2-1 of various conventional dimensions from the handle to the key hole and used for fixing the adjustable key hole module 1-1. An indicating arrow 1-1-1 and a stud 1-1-2 are arranged on the back of the adjustable key hole module 1-1. The fixing mode of the adjustable key hole module 1-1 is that a fastening screw 1-3 penetrates through a corresponding screw hole 1-2-2 of the bottom plate 1-2 and is finally locked and fixed with a stud 1-1-2 of the bottom plate 1-2.

Description

Technical Field

[0001] The present invention relates to a door lock with a panel, and particularly to a door lock with an adjustable center distance from the handle to the keyhole. Background Art

[0002] As is well known, common door locks with panels on the market are composed of a handle, a panel, a lock body, and a lock core, and a keyhole coaxial with the lock core hole is provided above or below the handle. However, due to historical development reasons, there are various lock bodies with different specifications of the distance between the handle and the lock core hole on the market. For example, the more common specifications are: 50, 68, 72, 85, 95, etc. Therefore, the distance from the handle to the keyhole on the door lock panel also has several common specifications corresponding to the lock body, such as 50, 68, 72, 85, 95, etc. For this reason, in order to adapt to different lock bodies, production enterprises need to manufacture door lock panels of different specifications, and users also must select door locks with corresponding panel specifications according to the specifications of the lock body in order to install and use them. Summary of the Invention

[0003] In summary, the present invention provides a door lock with an adjustable center distance from the handle to the keyhole, and the main feature is that the center distance position from the handle to the keyhole can be adjusted according to various common lock bodies of different specifications. Brief Description of the Drawings

[0004] Att Figure 1 : Schematic diagram of the structural composition of the present invention.

[0005] Att Figure 2 : Schematic diagram of the structure of the adjustable keyhole module of the present invention.

[0006] Att Figure 3 : Schematic diagram of the back structure of the front panel assembly of the present invention. Detailed Description of the Invention

[0007] The present invention is composed of a front / rear panel assembly 1, a lock body assembly 2, and a lock core assembly 3. An adjustable keyhole module 1-1 that can move up and down in the notch is provided inside the front panel assembly. The bottom plate 1-2 is provided with a numerical value 1-2-1 for displaying various conventional dimensional specifications from the handle to the keyhole and a screw hole 1-2-2 for fixing the adjustable keyhole module 1-1.

[0008] The adjustable keyhole module 1-1 is provided with an indicating arrow 1-1-1 and a stud 1-1-2 on its back.

[0009] The fixing method of the adjustable keyhole module 1-1 is that a fastening screw 1-3 passes through the corresponding screw hole 1-2-2 of the bottom plate 1-2 and is finally locked and fixed with its stud 1-1-2.

[0010] If it is necessary to adjust the position of the adjustable keyhole module 1-1, it needs to be moved to the position with the required dimensional specifications. When its stud 1-1-2 is aligned with the screw hole 1-2-2 of the bottom plate 1-2, install and tighten the fastening screw 1-3.

Claims
