Description

Technical Field

[0001] This utility model relates to the field of lock technology, and more specifically, to the lock cylinder of a three-point communication idle rack lock. Background Technology

[0002] A free-spinning lock cylinder is a type of anti-theft lock cylinder, mainly used in security protection fields such as anti-theft doors. It consists of components such as a shell, lock cylinder, blades, pins, and clutch mechanism.

[0003] Based on the above, the inventors have discovered that traditional single-point communication idle-rotation cabinet lock cylinders generally have low communication efficiency and poor communication stability, especially in scenarios with complex encryption algorithms, such as the SM4 online asymmetric algorithm, which involves a large amount of encrypted data. The single-point communication structure cannot meet the requirements. At the same time, the lock cylinder and pin tumbler have low matching precision, resulting in a poor feel when unlocking and easy wear after long-term use, affecting the lifespan of the lock. Therefore, in view of this, the inventors have researched and improved the existing structure to provide a three-point communication idle-rotation padlock cylinder, aiming to achieve a more practical value. Utility Model Content

[0004] 1. Technical problems to be solved

[0005] To address the problems existing in the prior art, the purpose of this utility model is to provide a three-point communication idle rack lock cylinder. It can precisely control the rotation angle and position of the cam by fixing a connecting plate to one end of the drive motor and setting a limiting rod on the connecting plate, which cooperates with the limiting groove on the outside of the cam. This improves the accuracy of the lock cylinder and the ball joint, reduces wear caused by insufficient cooperation accuracy, and extends the service life of the lock. At the same time, the multi-point communication structure design greatly improves the communication efficiency and effectively avoids the signal interference and data transmission bottleneck problems that may occur in single-point communication.

[0006] 2. Technical Solution

[0007] To solve the above problems, the present invention adopts the following technical solution.

[0008] The lock cylinder of the three-point communication idle rack lock includes a lock shell. One end of the lock shell is open, and a lock cover is fixedly connected to the opening. The other end of the lock shell has an integrally formed boss. A main control board and a drive motor are fixedly installed inside the lock shell, and the main control board and the drive motor are electrically connected by wires. The lock cover has a lock cylinder hole, and an insulating seat is installed in the lock cylinder hole. The insulating seat has a terminal that is electrically connected to the main control board. The output shaft of the drive motor extends into the boss and is connected to a cam by a key. Limit holes are opened on both sides of the boss, and steel balls are embedded in the limit holes. The outer circumference of the steel ball contacts the outer circumference of the cam. Grooves are opened on both sides of the cam, and the steel ball is adapted to the corresponding groove.

[0009] Furthermore, the terminal includes a first contact, a second contact, and a third contact, wherein the first contact is a positive contact, the second contact is a common negative contact, and the third contact is a communication contact.

[0010] Furthermore, the first contact, the second contact, and the third contact are evenly distributed at equal intervals.

[0011] Furthermore, a connecting plate is fixedly connected to one end of the drive motor near the boss. A limit rod is integrally formed on one side of the connecting plate, and a limit groove is opened on the outer side of the cam. One end of the limit rod extends into the limit groove.

[0012] Furthermore, two symmetrical positioning blocks are fixedly connected to the outer periphery of the lock cover near the lock housing. A positioning groove is provided on the outer periphery of the lock housing corresponding to the position of the positioning block, and the corresponding positioning block is engaged in the positioning groove.

[0013] Furthermore, the outer periphery of the boss is fixedly connected with an extension edge.

[0014] 3. Beneficial effects

[0015] Compared with existing technologies, the advantages of this utility model are:

[0016] (1) This solution improves the overall structural stability by optimizing the connection method of the lock shell, lock cover, and internal components in the lock cylinder structure design. The lock cover and lock shell are connected by a positioning block and positioning groove. This design not only facilitates installation but also enhances the tightness of the connection between the two, preventing loosening during long-term use and thus affecting the normal operation of the lock cylinder. At the same time, in the connection part between the drive motor and the cam, a connecting plate is fixed at one end of the drive motor, and a limiting rod is set on the connecting plate. It cooperates with the limiting groove on the outside of the cam to accurately control the rotation angle and position of the cam, improving the accuracy of the lock cylinder and the pin engagement. This design makes the unlocking process smoother and provides a better feel, while reducing wear caused by insufficient engagement accuracy and extending the service life of the lock.

[0017] (2) This scheme uses three contacts—the first, second, and third contacts—which are evenly distributed at equal intervals. This multi-point communication structure design significantly improves communication efficiency. In complex scenarios with large amounts of encrypted data, such as the SM4 online asymmetric algorithm, it can achieve more efficient data transmission and ensure communication stability. By assigning different functions to different contacts—the first contact as the positive contact, the second contact as the common negative contact, and the third contact as the communication contact—the functions of each contact are clearly defined and they work together, effectively avoiding signal interference and data transmission bottlenecks that may occur in single-point communication.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0043] Example:

[0044] Please see Figures 1-4 The lock cylinder of the three-point communication idle rack lock includes a lock shell 1. One end of the lock shell 1 is open and a lock cover 2 is fixedly connected to the opening. The other end of the lock shell 1 has an integrally formed boss 3. The main control board 4 and the drive motor 5 are fixedly installed inside the lock shell 1, and the main control board 4 and the drive motor 5 are electrically connected by wires. The lock cover 2 has a lock cylinder hole 6, and an insulating seat 7 is installed in the lock cylinder hole 6. The insulating seat 7 has a terminal that is electrically connected to the main control board 4. The output shaft of the drive motor 5 extends into the boss 3 and is connected to a cam 11 by a key. Limit holes are opened on both sides of the boss 3, and steel balls 12 are embedded in the limit holes. The outer periphery of the steel balls 12 contacts and connects with the outer periphery of the cam 11. Grooves 13 are opened on both sides of the cam 11, and the steel balls 12 are adapted to the corresponding grooves 13.

[0045] See Figure 3 The terminal includes a first contact 8, a second contact 9, and a third contact 10. The first contact 8 is the positive contact, the second contact 9 is the common negative contact, and the third contact 10 is the communication contact. In use, the first contact 8 is the positive contact, representing the positive terminal of the power supply (3.7V), the second contact 9 is the common negative contact, representing the common negative terminal, and the third contact 10 is the communication contact, indicating that the data for sending and receiving the key is transmitted through this contact.

[0046] See Figure 3 The first contact 8, the second contact 9, and the third contact 10 are evenly distributed at equal intervals, which can ensure the stability and consistency of signal transmission during use and avoid signal interference or poor transmission due to contact spacing issues.

[0047] See Figure 4 The drive motor 5 is fixedly connected to a connecting plate 14 near the boss 3. A limit rod 15 is integrally formed on one side of the connecting plate 14. A limit groove 16 is opened on the outer side of the cam 11. One end of the limit rod 15 extends into the limit groove 16.

[0048] See Figure 4 Two symmetrical positioning blocks 17 are fixedly connected to the outer periphery of the lock cover 2 near the lock shell 1. A positioning groove 18 is provided on the outer periphery of the lock shell 1 at the position corresponding to the positioning block 17, and the corresponding positioning block 17 is engaged in the positioning groove 18.

[0049] See Figure 2 and Figure 4 The outer periphery of the boss 3 is fixedly connected with an extension edge 19.

[0050] In use: Insert the electronic key into the lock cylinder hole 6. The electronic key corresponds to three contacts. The electronic key first supplies power to the main control board 4 through the first contact 8 and the second contact 9. After powering on, it analyzes whether the key number is allowed to open the lock. If the match is successful, the main control board 4 circuit supplies power to the drive motor 5. After the drive motor 5 starts, its drive shaft drives the cam 11 to rotate to the stall position. The stalled cam 11 pushes out the steel ball 12, which will lock the external clutch. Rotating the entire lock cylinder will open the lock. The overall communication stability and efficiency are greatly improved, reducing signal interruption, bit error and other problems, ensuring the accuracy of data transmission, and effectively improving the reliability of the lock in the field of security protection.
