Description

Technical Field

[0001] This utility model relates to the field of high-security sealing device technology, specifically a lock cylinder structure with a compact and well-fitting design. Background Technology

[0002] High-security seals are a type of sealing device used on containers, trucks, vans, and other similar vehicles. They are designed to be sealed in a one-time manner, preventing damage and tampering with traditional lead seals, which are less robust and prone to reverting to their original state after being broken.

[0003] Currently, length errors are prone to occur in the production of lock cylinder bodies. When the lock cylinder body is assembled with a plastic shell to form the lock cylinder structure, the lock cylinder body with length errors slides unstablely up and down within the finished product. The sliding lock cylinder body affects the success rate of the lock head and lock cylinder body insertion and locking, which requires operators to insert and check the locking effect multiple times, which undoubtedly reduces the convenience of operation. Utility Model Content

[0004] The purpose of this utility model is to provide a lock cylinder structure with a compact and well-fitting design, which solves the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a compact and well-fitting lock cylinder structure, comprising a housing, a lock cylinder body, and a bottom housing. The bottom housing has a protrusion in the middle. The lock cylinder body is fitted into the housing, and the bottom of the housing is fitted with the bottom housing. The protrusion abuts against the bottom of the lock cylinder body. The lock cylinder body has an insertion interface, and the top of the housing has an opening adapted to the insertion interface.

[0006] Preferably, the lock cylinder body has at least two engaging metal strips, and the engaging metal strips are located inside the insertion interface.

[0007] Preferably, the surface of the casing is provided with anti-slip texture.

[0008] Preferably, the bottom of the casing is further provided with a groove, which is close to the bottom shell.

[0009] Preferably, both the outer shell and the bottom shell are made of plastic, and the bottom shell is integrally formed with the protrusion.

[0010] Preferably, the inner wall of the housing is provided with multiple engaging parts, which are arranged in a circumferential array on the inner wall of the housing, and the outer circumferential wall of the lock cylinder body abuts against the multiple engaging parts.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0012] This utility model features a protrusion on the bottom shell, which can be used to press the lock cylinder body against itself, preventing the lock cylinder body from sliding up and down within the lock cylinder structure. This improves the success rate of the lock cylinder structure and the lock head engaging, while also enhancing the locking effect and ease of operation. Attached Figure Description

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] In the description of this utility model, it should be understood that the terms "center," "longitudinal," "lateral," "upper," "lower," "front," "rear," "left," "right," "horizontal," "vertical," "top," "inner," and "outer," etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0021] Please see Figures 1 to 3This utility model provides an embodiment of a compact and well-fitting lock cylinder structure, including a housing 1, a lock cylinder body 2, and a bottom shell 3. Both the housing 1 and the bottom shell 3 are made of plastic. A protrusion 4 is provided in the middle of the bottom shell 3. The lock cylinder body 2 is fitted into the housing 1, and the bottom of the housing 1 is fitted with the bottom shell 3. The protrusion 4 abuts against the bottom of the lock cylinder body 2. The protrusion 4 can be used to press the lock cylinder body 2 tightly to prevent the lock cylinder body 2 from sliding up and down in the lock cylinder structure. The lock cylinder body 2 is provided with an insertion interface 5, which allows the lock head structure to be inserted. The top of the housing 1 is provided with an opening 6 that matches the insertion interface 5. The lock head structure 7 passes through the opening 6 and is inserted into the insertion interface 5, achieving the locking effect between the lock head structure and the lock cylinder structure. The stable and fixed lock cylinder body 2 can improve the success rate of the lock cylinder structure and lock head insertion and locking, and at the same time improve the locking effect and the ease of operation.

[0022] Furthermore, the plastic material has excellent deformation properties. When the protrusion 5 presses against the lock cylinder body 2, the bottom shell 3 can achieve a certain degree of curvature deformation, while pressing against the lock cylinder body 2 and preventing the sleeve 1 and bottom shell 3 from being unable to fit together due to the excessive overall length of the protrusion 5 and the lock cylinder body 2.

[0023] Furthermore, the lock cylinder body 2 is provided with at least two engaging metal strips 8, and the engaging metal strips 8 are located inside the insertion interface 5.

[0024] refer to Figures 1 to 4 It also includes a lock head structure 7, which is provided with an annular groove 9. The end of the lock head structure 7 is truncated cone-shaped, which can be inserted between two locking metal strips 8. Through the truncated cone-shaped structure, it expands outward. When the locking metal strip 8 moves to the annular groove 9, the locking metal strip retracts and resets, and the locking metal strip locks and engages with the annular groove 9, so that the lock head structure 7 and the lock cylinder structure have a locking effect.

[0025] Furthermore, the surface of the cover 1 is provided with anti-slip texture 10, which improves the user's grip and facilitates the assembly of the cover 1 and the bottom shell 3.

[0026] Furthermore, a slot 11 is provided at the bottom of the casing 1. The slot 11 is close to the bottom shell 3. The slot 9 allows rod-shaped items to be inserted. After the rod-shaped items are inserted into the slot 9, the bottom shell 3 can be pried off the casing 1.

[0027] Furthermore, the bottom shell 3 and the protrusion 4 are integrated into one piece, and the protrusion 4 is also made of plastic.

[0028] The inner wall of the housing 1 is provided with multiple engaging parts 12, which are arranged in a circumferential array on the inner wall of the housing 1. The outer circumferential wall of the lock cylinder body 2 abuts against the multiple engaging parts 12. The above structure can prevent the lock cylinder body 2 from sliding to the circumferential side, further improving the connection stability of the lock cylinder body 2, while increasing the success rate of the lock cylinder structure and the lock head structure 7 to engage and lock, and improving the locking effect and ease of operation.

[0029] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
