Description

Technical field

[0001] The utility model relates to an installation structure of a door lock cylinder. [Background Technology]

[0002] In a common door lock, the lock core is passed through the lock shell and is connected to the screw hole on the lock core through a positioning screw on the side of the lock shell where the lock tongue extends, so as to fix the lock core on the lock shell. However, since the lock core is usually arranged relatively far away from the positioning screw, when the user replaces the lock core by himself at a later time, it is difficult for the positioning screw to align with the screw hole on the lock core for connection, which makes the lock core difficult to install and replace. There is currently no better way to solve this problem.

[0003] Therefore, it is necessary to make further improvements. [Utility Model Content]

[0004] The purpose of the present invention is to overcome the above problems. We provide a mounting structure for a door lock cylinder, which can facilitate users to disassemble and replace the lock cylinder.

[0005] To achieve the above-mentioned purpose, the utility model provides an installation structure of a door lock cylinder, which includes a lock shell, a lock cylinder and a fixing seat. The lock shell is provided with a lock cylinder installation hole for the lock cylinder to pass through, and the fixing seat is provided with a positioning hole that matches the shape of the lock cylinder. The fixing seat is installed and fixed on the outer side of the lock shell, and a first screw hole is provided on the side of the fixing seat. A second screw hole is provided at the position of the lock cylinder corresponding to the first screw hole. A fastening screw connects the first screw hole and the second screw hole to fix the lock cylinder on the fixing seat.

[0006] In one or more embodiments, a third screw hole is provided on the fixing base, and a fourth screw hole is provided on the lock housing at a position corresponding to the third screw hole, and a fixing screw connects the third screw hole and the fourth screw hole to fix the fixing base on the lock housing.

[0007] In one or more embodiments, the thickness of the fixing seat is 5MM-10MM, and the outer end surface of the fixing seat is flush with the end surface of the side connected to the lock core.

[0008] In one or more embodiments, the fixing seat is one of a plastic fixing seat, a stainless steel fixing seat, and an aluminum alloy fixing seat.

[0009] In one or more embodiments, an arc-shaped guide structure is provided on the side of the positioning hole connected to the lock core.

[0010] Compared with the background technology, the effect of the present invention is that the installation structure can facilitate the user to quickly install and fix the lock core when replacing the lock core by himself in the future. The lock core is fixed by a fixing seat, which replaces the traditional method of fixing the lock core from the side of the door with a positioning screw, saving the step of aligning the positioning screw with the lock core.

Brief Description of the Drawings

[0011] Figure 1 This is a schematic diagram of the structure of the fixing base fixing the lock cylinder to the lock housing in this embodiment;

[0012] Figure 2 This is a structural diagram of the embodiment before the fixing base fixes the lock cylinder. [Specific implementation method]

[0013] This section will describe in detail the specific embodiments of the present invention. The preferred embodiments of the present invention are shown in the accompanying drawings. The purpose of the accompanying drawings is to supplement the description of the text part of the specification with graphics, so that people can intuitively and vividly understand each technical feature and overall technical solution of the present invention, but it cannot be understood as a limitation on the scope of protection of the present invention.

[0014] See attached Figure 1 The present application provides an installation structure for a door lock cylinder, which includes a lock shell 1, a lock cylinder 2 and a fixing base 3. The lock shell 1 is provided with a lock cylinder installation hole for the lock cylinder to pass through, and the fixing base 3 is provided with a positioning hole 4 that matches the shape of the lock cylinder. The fit between the positioning hole and the shape of the lock cylinder can prevent the lock cylinder from shaking. The fixing base is installed and fixed on the outer side of the lock shell 1, and a first screw hole 5 is provided on the side of the fixing base 3. The lock cylinder 2 is provided with a second screw hole 6 at the position corresponding to the first screw hole. The fastening screw connects the first screw hole and the second screw hole to fix the lock cylinder 2 on the fixing base 3. During installation, the user can first assemble and fix the lock cylinder and the fixing base together by fastening the screws, and then pass the lock cylinder through the lock cylinder installation hole on the lock shell, and then fix the fixing base on the lock shell, thereby fixing the lock cylinder to the lock shell.

[0015] Preferably, a third screw hole 7 is provided on the fixing base 3, and a fourth screw hole 8 is provided on the lock shell 1 at a position corresponding to the third screw hole. The fixing screw connects the third screw hole and the fourth screw hole to fix the fixing base on the lock shell. The fixing base is installed and fixed using the fixing screw, which has the advantage of easy installation and disassembly.

[0016] The thickness of the fixing seat 3 is 5MM-10MM, and the outer end face of the fixing seat is flush with the end face of the side connected to the lock core 2. The preferred thickness of the fixing seat is 5MM, 6MM, 8MM, or 10MM. The specific thickness of the fixing seat depends on the length of the lock core protruding from the lock shell.

[0017] The fixing seat 3 is one of a plastic fixing seat, a stainless steel fixing seat, and an aluminum alloy fixing seat. The specific material of the fixing seat is determined according to actual conditions and is not limited here.

[0018] The positioning hole 4 is provided with an arc-shaped guide structure on the side connected to the lock core 2, and the arc-shaped guide structure can help the lock core to connect with the positioning hole.

[0019] The above description is only a preferred embodiment of the present invention. The protection scope of the present invention is not limited to the above embodiment. Any equivalent modifications or changes made by ordinary technicians in this field based on the content disclosed in the present invention should be included in the protection scope recorded in the claims.
