Description

Technical Field

[0001] This utility model relates to the field of door lock technology, specifically to a lock cylinder structure. Background Technology

[0002] A lock cylinder is a mechanism used for opening and closing doors. Traditional lock cylinders are unlocked by inserting and rotating a key. With continuous technological advancements, lock cylinders with different functions have appeared on the market. For example, patent application number CN201621436247.9 discloses an anti-breakage lock cylinder, and patent application number CN201210374468.8 discloses a lock cylinder and key. These lock cylinder structures have multiple holes distributed on the lock shell, and each hole is equipped with a pin tumbler assembly. Currently, the price of the main material for manufacturing lock cylinders, such as copper, is rising. In order to improve the competitiveness of their products, many companies are working on how to reduce costs more efficiently, but there is currently no lock cylinder structure that effectively reduces costs. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a lock cylinder structure that is simple in structure, has lower manufacturing and transportation costs, and is more portable.

[0004] To solve the above problems, the present invention adopts the following technical solution:

[0005] A lock cylinder structure includes a lock shell, a lock cylinder, and a spring assembly. The lock cylinder is installed inside the lock shell. Lock grooves are distributed on either the left or right side or both sides of the lock shell. Support seats are fixed relative to each other on either the left or right side or both sides of the lock shell within the lock grooves. The spring assembly is installed on the lock shell and passes through the support seats.

[0006] A further technical solution is that the support base is relatively fixed in the lock groove on either side of the lock housing by interference fit or adhesive bonding. The support base can be directly pressed into the lock groove on the lock housing by interference fit, or it can be bonded by strong adhesive, or other relatively fixed methods are also acceptable.

[0007] A further technical solution is that the support base has a "T" shaped structure and connecting ribs are distributed on one or both sides. The support base can be directly pressed into the lock groove on the lock shell and fixed in place by means of the connecting ribs through interference fit.

[0008] A further technical solution is that the support base has through holes distributed laterally for housing and supporting the spring assembly.

[0009] The beneficial effects of this utility model are as follows: Compared with existing lock cylinders on the market, this utility model has a lock cylinder structure with lock grooves opened on either side of the shell, and a support seat fixed in the lock groove. There is a relatively large gap between the lock groove and the support seat in the lock shell. These gaps can greatly reduce the amount of metal used, reduce the weight of the lock cylinder, and reduce manufacturing and transportation costs. It is also more convenient to carry, thus improving the company's competitive advantage in the market. Attached Figure Description

[0017] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more definite definition of the scope of protection of the present invention.

[0018] See Figures 1 to 5 As shown, a lock cylinder structure includes a lock shell 1, a lock cylinder 3, and a spring assembly 4. The lock cylinder 3 is installed inside the lock shell 1. Lock grooves 5 are distributed on either the left or right side or both sides of the lock shell 1. Support seats 2 are fixed relative to each other on either the left or right side or both sides of the lock shell 1 and located in the lock grooves 5. The spring assembly 4 is installed on the lock shell 1 and passes through the support seat 2.

[0019] The support base 2 is fixed to the lock groove 5 on either side of the lock housing 1 by interference fit or adhesive bonding. The support base 2 can be directly pressed into the lock groove 5 on the lock housing 1 by interference fit, or it can be bonded with strong adhesive, or other methods of fixation are also acceptable. The support base 2 has a "T" shaped structure and connecting ribs 8 distributed on one or both sides. These connecting ribs 8 allow the support base 2 to be directly pressed into the lock groove 5 on the lock housing 1 by interference fit and fixed in place. The support base 2 has through holes 7 distributed laterally for internal installation and support of the spring assembly 4.

[0020] In this embodiment, a lock groove 5 is formed by drilling a hole in the lock housing 1. Then, the support base 2 is directly pressed into the lock groove 5 on the lock housing 1 by interference fit or fixed in the lock groove 5 by adhesion. The lock housing 1 is also distributed with limiting holes 9. The through hole 7 on the support base 2 is aligned with the limiting hole 9 on the lock housing 1. The spring assembly 4 is then installed into the lock housing 1. The lock housing 1 is also distributed with lock cylinder holes 6. The lock cylinder 3 is installed in the lock cylinder holes 6 on the lock housing 1. The support base 2, lock groove 5 and spring assembly 4 can be distributed on either the left or right side or both sides of the lock housing 1. In this embodiment, they are distributed on the left and right sides.

[0021] It should be noted that, in this document, the terms “comprising,” “including,” or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such process, method, article, or apparatus.
