Description

Technical Field

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

[0002] As the core component for enabling the opening and closing of locks, the stability of the connection between the lock cylinder and the transmission components, the ease of disassembly and assembly, and the reliability of its movement directly affect the overall performance and service life of the lock. Currently, most common lock cylinders and transmission components on the market are assembled using methods such as bolt fastening and welding. While bolt fastening ensures a certain connection strength, it requires specialized tools to tighten each bolt individually during lock cylinder installation or subsequent maintenance and disassembly. This is not only cumbersome but also prone to problems such as stripped threads or corrosion, leading to difficulties in assembly and disassembly, significantly reducing the efficiency of lock assembly and maintenance. Welding, on the other hand, directly fixes the lock cylinder and transmission component as a single unit. While this avoids loosening, if the lock cylinder or transmission component malfunctions and needs replacement, both components must be replaced together, failing to meet the need for flexible replacement of lock parts.

[0003] Therefore, it is necessary to propose a lock-locking structure to solve the above problems. Utility Model Content

[0004] (a) Technical problems to be solved The purpose of this utility model is to provide a lock head locking structure to solve the problem of inconvenient disassembly and assembly of existing lock heads and transmission components mentioned in the background art.

[0005] (II) Technical Solution To achieve the above objectives, this utility model provides the following technical solution: a lock head locking structure, comprising a transmission plate, a base plate, and a lock head. A limiting plate is fixedly connected to the base plate, and a cover plate is detachably installed on the side of the limiting plate away from the base plate. The cover plate, the base plate, and the limiting plate cooperate to form a limiting cavity. The transmission plate is slidably connected to the base plate, and one end of the transmission plate extends through to the inside of the limiting cavity and is fixedly connected to a strip-shaped insert perpendicular to its sliding direction. The lock head is slidably disposed within the limiting cavity, and a strip-shaped slot adapted to the strip-shaped insert is provided on one side of the lock head. The lock head is inserted into the transmission plate through the strip-shaped insert.

[0006] Preferably, the limiting plate is vertically fixed to one side of the base plate, and the cover plate is fixedly connected to the limiting plate by screws.

[0007] Preferably, a stop bar is provided on the inner side of the limiting cavity at a position corresponding to the transmission plate, and the stop bar is fixedly connected to the base plate.

[0008] Preferably, the length of the strip-shaped insert is greater than the width of the transmission plate.

[0009] Preferably, the width of the limiting cavity is adapted to the length of the lock head.

[0010] Preferably, side plates are vertically fixedly connected to both sides of the transmission plate along its length, and the side plates are slidably connected to the limiting plate.

[0011] Preferably, the cross-sections of the strip-shaped insert and the strip-shaped slot are both T-shaped.

[0012] (III) Beneficial Effects Compared with the prior art, the present invention provides a lock head locking structure, which has the following beneficial effects: 1. The lock head locking structure connects the transmission plate and the lock head, and limits the range of motion of the lock head through the limiting cavity to prevent it from falling off the transmission plate, thus making the lock head easier to disassemble and assemble.

[0013] 2. The locking structure of this lock head restricts the range of motion of the lock head by setting a limiting cavity and setting a stop bar to limit the transmission plate, so that it can only move within a preset area, thereby improving its motion reliability. Attached Figure Description

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0017] Please see Figure 1-3As shown, a lock head locking structure includes a transmission plate 1, a base plate 3, and a lock head 4. A limiting plate 7 is fixedly connected to the base plate 3. A cover plate 2 is detachably installed on the side of the limiting plate 7 away from the base plate 3. The cover plate 2, the base plate 3, and the limiting plate 7 cooperate to form a limiting cavity. The transmission plate 1 is slidably connected to the base plate 3. One end of the transmission plate 1 extends through to the inside of the limiting cavity and is fixedly connected to a strip-shaped insert 5 perpendicular to its sliding direction. The lock head 4 is slidably arranged in the limiting cavity. A strip-shaped slot 9 adapted to the strip-shaped insert 5 is opened on one side of the lock head 4. The lock head 4 is inserted into the transmission plate 1 through the strip-shaped insert 5. Specifically, the opening of the limiting cavity faces one edge of the base plate 3; the cross-section of the strip-shaped insert 5 and the strip-shaped slot 9 are both T-shaped.

[0018] During assembly, the lock head 4 is inserted into one end of the transmission plate 1 via the strip-shaped insert 5 and the strip-shaped slot 9. Then, the lock head 4 is placed in the limiting cavity, with one end of the transmission plate 1 extending to the outside of the limiting cavity. Finally, the cover plate 2 is fixedly connected to the limiting plate 7 to limit the transmission plate 1 and the lock head 4. Simultaneously, the limiting plate 7 prevents the lock head 4 from detaching from the transmission plate 1, thus achieving the locking connection of the lock head 4. The lock head 4 slides within the limiting cavity, allowing one end to extend or retract.

[0019] Specifically, the limiting plate 7 is vertically fixed to one side of the base plate 3, and the cover plate 2 is fixedly connected to the limiting plate 7 by screws. By using screws to fix the cover plate 2 to the limiting plate 7, the cover plate 2 is easy to install and remove.

[0020] To limit the range of motion of the lock cylinder 4, a stop bar 6 is provided on the inner side of the limiting cavity at a position corresponding to the transmission plate 1. The stop bar 6 is fixedly connected to the base plate 3. The stop bar 6 limits the movement of the transmission plate 1. When the transmission plate 1 slides to the stop bar 6, one end of the lock cylinder 4 extends out of the limiting cavity, such as... Figure 1 As shown. By setting the length of the strip-shaped insert 5 to be greater than the width of the transmission plate 1, when the lock head 4 retracts into the limiting cavity, the strip-shaped insert 5 abuts against the inner wall of the limiting cavity to control the range of motion of the lock head 4.

[0021] Because the lock head 4 is slidably assembled with the transmission plate 1, the width of the limiting cavity is matched with the length of the lock head 4 to prevent the lock head 4 from sliding along its length. Under the limiting of the limiting plate 7, the lock head 4 is prevented from falling off the transmission plate 1.

[0022] Specifically, side plates 8 are vertically fixed to both sides of the transmission plate 1 along its length, and the side plates 8 are slidably connected to the limiting plate 7. By setting the side plates 8 to increase the contact area, and by the cooperation between the side plates 8 and the limiting plate 7 to guide, the stability of the transmission plate 1 during the sliding process is improved, thereby preventing it from tilting or getting stuck.

[0023] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
