Description

Technical Field

[0001] The utility model relates to a door lock. Background Art

[0002] Smart door locks are box-shaped structures fixed on door panels for mounting handles, accommodating components such as components connecting the handle end to the lock core, and other functional components. Existing door locks are mainly composed of three parts, namely, a panel, a cover plate, and a shell. The panel and the cover plate are respectively mounted on the front and back sides of the shell to form a box shape, and some functional components are installed in the box. The shell is generally formed by die casting, which has a high manufacturing cost. In addition, since only a certain number of shells can be produced each time by die casting, the production efficiency is low. Therefore, the existing structure needs to be further improved. Utility Model Content

[0003] The utility model aims to provide a door lock with simple structure, low manufacturing cost and high assembly efficiency.

[0004] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0005] A door lock comprises a panel assembly and a shell, wherein the panel assembly comprises an operating panel and a panel bracket, wherein the shell is made of a tubular profile with openings at both ends, a window for installing the operating panel is opened on the front wall of the shell, the panel bracket is correspondingly installed and fixed in the shell, the operating panel is installed and fixed on the panel bracket to close the window, and the openings at both ends of the shell are blocked with blocking pieces.

[0006] The advantage of the utility model is that the shell is made of tubular profiles, and the material of the required length can be cut from the formed profile, and the window can be processed by punching and the like, which can reduce the manufacturing cost of the shell. During assembly, the panel bracket can be installed in the shell as needed, thereby saving part of the assembly process and improving production efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

[0012] As attached Figure 1 To Attachment Figure 5 As shown, the door lock includes a panel assembly and a shell 1 , and the panel assembly includes an operating panel 2 and a panel bracket 3 .

[0013] The shell 1 is made of a tubular profile with openings 11 at both ends. A window 12 for installing the operation panel 2 is opened on the front wall of the shell 1. The panel bracket 3 is correspondingly installed and fixed in the shell 1. The operation panel 2 is installed and fixed on the panel bracket 3 to close the window 12. The openings 11 at both ends of the shell 1 are blocked by a blocking piece 4.

[0014] The panel bracket 3 enters the housing 1 through the opening 11 at the upper end or the lower end of the housing 1 and is fixed at a position corresponding to the window 12 in the housing 1. The panel bracket 3 is provided with a plurality of mounting posts, each of which has a screw hole. The rear wall of the housing 1 is provided with through holes corresponding to the mounting posts of the panel bracket 3, and the threaded holes of the screws pass through the through holes and are screwed to the screw holes.

[0015] A sealing member is provided between the operating panel 2 and the periphery of the window 12 .

[0016] The plugging member 4 includes a plug 41 and an inserting portion 42 connected together. The inserting portion 42 is inserted into the shell body with interference fit, and an end surface of the plug 41 facing the inserting portion 42 abuts against the end surface of the shell body 1.

[0017] The insertion portion 42 of the blocking member 4 is provided with a connecting column having a screw hole. The rear wall of the housing 1 is provided with a through hole corresponding to the connecting column of the blocking member 4. The threaded hole of the screw passes through the through hole and is screwed to the screw hole.
