Description

Technical Field

[0001] The utility model belongs to the technical field of lock cores, and in particular relates to a novel crescent lock core. Background Art

[0002] The lock core is the verification component of the lock. A general mechanical lock is to insert the key into the lock, use the concave or convex points on the key to correspond to the lock bolt of the lock, and then move the lock bolt to a predetermined position to complete the rotation to unlock. For example, the Chinese patent application number is: 201520334989.X, and the patent name is: A lock core mechanism of a preparation chamber, including a sensing shell, a lock core, and a top ball assembly provided between the sensing shell and the lock core. Although it can meet the general usage requirements, its lock core is a complete structure, which is not conducive to saving materials and reducing costs. At the same time, the shape of its slot is relatively simple, and its applicability and practicality are limited. Summary of the Invention

[0003] The purpose of the utility model is to provide a novel crescent lock core which has a reasonable structure and is conducive to reducing costs.

[0004] The technical solution for achieving the purpose of the utility model is a new crescent lock cylinder, comprising a lock cylinder housing and a lock core located in the lock cylinder housing, wherein the lock core is provided with a crescent-shaped key slot, and the middle portions of the symmetrical side walls of the lock cylinder are provided with avoidance slots, wherein the avoidance slots are connected to the crescent-shaped key slot;

[0005] A plurality of marble holes are provided on the side wall of the lock core;

[0006] Two guiding ridges are integrally formed on the inner arc edge of the crescent-shaped key slot.

[0007] It is further preferred that the outer end edge of the lock core is integrally formed with a mounting flange.

[0008] It is further preferred that an annular groove is provided on the outer wall of the inner end of the lock core.

[0009] More preferably, the number of the avoidance slots is three or four.

[0010] It is further preferred that the lock cylinder is a copper lock cylinder or an aluminum lock cylinder.

[0011] The present invention has positive effects: the structure of the present invention is reasonably arranged, and an avoidance slot is arranged in the middle of the symmetrical side wall of the lock core, and the avoidance slot is communicated with the crescent-shaped key slot, which is not only conducive to saving materials and thus helping to reduce the overall cost, but also has a guide ridge on the inner arc edge of the crescent-shaped key slot, which is conducive to guiding the insertion of the key, improving the stability and effectiveness of use, and has strong applicability and good practicality.

[0017] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention. Example

[0018] See Figures 1 to 3 As shown, a new type of crescent lock cylinder includes a lock cylinder shell 1 and a lock core 2 in the lock cylinder shell, and a crescent-shaped key slot 3 is provided on the lock core. In this embodiment, the lock cylinder shell and the lock core are conventional structures of the prior art, so they are not recorded in detail.

[0019] In actual use, the symmetrical side walls of the lock core are each provided with a relief slot 4 in the middle, communicating with the crescent-shaped keyway. Several ball holes 5 are also provided on the side walls of the lock core. The provision of the relief slots saves material for the lock core without affecting its normal operation. Furthermore, in actual use, two guide ridges 6 are integrally formed on the inner curved edge of the crescent-shaped keyway. These guide ridges facilitate key guidance, improving the smoothness and reliability of key use.

[0020] In actual use, the outer end of the cylinder is integrally formed with a mounting flange 7. Furthermore, an annular groove 8 is provided on the inner outer wall of the cylinder. The mounting flange provides a fixed position for installation, while the annular groove allows for quick and smooth installation of the cylinder.

[0021] In actual application, the number of the avoidance slots is three or four. The lock core is a copper lock core or an aluminum lock core.

[0022] The present invention has positive effects: the structure of the present invention is reasonably arranged, and an avoidance slot is arranged in the middle of the symmetrical side wall of the lock core, and the avoidance slot is communicated with the crescent-shaped key slot, which is not only conducive to saving materials and thus helping to reduce the overall cost, but also has a guide ridge on the inner arc edge of the crescent-shaped key slot, which is conducive to guiding the insertion of the key, improving the stability and effectiveness of use, and has strong applicability and good practicality.

[0023] The standard parts used in this embodiment can be purchased directly from the market, and the non-standard structural components described in the specification can also be directly processed according to existing technical common sense without any doubt. At the same time, the connection method of each component adopts the mature conventional means in the existing technology, and the machinery, parts and equipment all adopt conventional models in the existing technology, so no specific description is given here.

[0024] Obviously, the above embodiments of the present invention are merely examples for the purpose of clearly illustrating the present invention and are not intended to limit the embodiments of the present invention. Those skilled in the art will readily appreciate that other variations or modifications based on the above description are possible. It is not necessary and impossible to enumerate all embodiments here. However, obvious variations or modifications arising from the essence of the present invention remain within the scope of protection of the present invention.
