Description

Technical Field

[0001] This utility model relates to the field of door hinges, specifically a detachable door hinge. Background Technology

[0002] Door hinges are a type of home decoration material. Hinges are usually bi-fold and consist of a pair of metal or non-metal blades connected by a pivot pin. They are components that connect two parts of an object and allow them to move.

[0003] Railway train door hinges need to be easily disassembled and assembled to handle special situations or facilitate door maintenance. Existing door hinges are difficult to disassemble and require multiple people to work together. Therefore, there is a need for a detachable door hinge. Summary of the Invention

[0004] The purpose of this invention is to address the shortcomings of the existing technology by providing a detachable door hinge.

[0005] To address the aforementioned issues, a detachable door hinge is provided, characterized in that it includes an A-door hinge, a B-door hinge, and a pivot. One end of the side wall of the A-door hinge is integrally cast with an A-rotating cylinder, which is a hollow cylinder. At least one set of fixing holes are evenly distributed on the A-door hinge and penetrate through the A-door hinge.

[0006] The side wall of the B-door hinge is integrally cast with a B-rotor cylinder, which is a hollow cylinder. A rotating shaft is provided inside the B-rotor cylinder, passing through both ends of the B-rotor cylinder. An A-limiting block is provided in the middle of the rotating shaft. The A-limiting block is clearance-fitted with the inner wall of the B-rotor cylinder cavity. A B-limiting block is provided at one end of the rotating shaft. At least one set of fixing holes are evenly distributed on the B-door hinge and pass through the B-door hinge.

[0007] Preferably, a spring is provided inside the B rotating cylinder, and the spring is disposed between the A limiting block and the inner surface of the cavity of the B rotating cylinder away from the B limiting block.

[0008] Preferably, the end of the rotating shaft away from the B limiting block passes through the A rotating cylinder.

[0009] Preferably, the A-rotor sidewall is bolted with bolts that penetrate the A-rotor sidewall and the rotating shaft.

[0010] In summary, the beneficial effects of this utility model are:

[0011] This invention achieves an improved effect by adding and modifying the door hinge structure. During installation, the rotating shaft is aligned with the A rotating cylinder, the B limiting block is pushed, and the rotating shaft is bolted together with bolts to complete the installation of the A door hinge and the B door hinge.

[0012] During disassembly, after the bolts are removed, the spring pushes the A limit block to drive the rotating shaft to be pulled away from the A rotating cylinder, thus completing the disassembly of the A door hinge and the B door hinge, thereby achieving convenient disassembly of the door hinges.
