Description

Technical Field

[0001] The utility model relates to the technical field of lock core lubrication, in particular to a lock core with a self-lubricating structure. Background Art

[0002] The term lock cylinder usually refers to a core component used in a lock. It is a key part of the lock and is responsible for controlling the opening and closing of the lock. The interior of the lock cylinder is composed of multiple moving parts, such as the lock cylinder column and the lock cylinder pin. These parts will move relative to each other during use, causing friction. Lubricants can reduce the friction between these moving parts and make the operation of the lock cylinder smoother. Lubrication can improve the performance of the lock cylinder, making it easier to rotate and reduce the force of opening and closing, which helps to ensure the reliability and efficient performance of the lock cylinder.

[0003] After searching, a lock core is disclosed in the announcement number: CN209469125U, including a lock shell, a lock core and a key. The lock shell is provided with a mounting hole, the lock core is provided with a key hole and a pin hole, and a pin is movably arranged in the pin hole. A trapezoidal groove is provided on the inner wall of the mounting hole of the lock shell, and the bottom width of the trapezoidal groove is smaller than the opening width of the trapezoidal groove, and the trapezoidal groove has a flat bottom surface and a flat wall surface. The bottom width L of the trapezoidal groove of the utility model is smaller than the opening width L′ of the trapezoidal groove, and the bottom surface and the wall surface of the groove are both flat. One end of the pin can slide smoothly from the trapezoidal groove to the inner wall of the mounting hole or from the inner wall of the mounting hole to the trapezoidal groove, which also makes the lock core rotate more smoothly relative to the lock shell, and the lock core is not prone to jamming. Compared with the traditional lock core, the utility model also omits the spring in the traditional lock core pin assembly, making the product smaller in size and more compact in structure.

[0004] In the above application, the bottom width L of the trapezoidal groove is smaller than the opening width L′ of the trapezoidal groove, and the bottom surface and the wall surface of the groove are both flat. One end of the pin can slide smoothly from the trapezoidal groove to the inner wall of the mounting hole or from the inner wall of the mounting hole to the trapezoidal groove, which also makes the lock core rotate more smoothly relative to the lock shell, and the lock core is not prone to jamming.
