[0018] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model with reference to the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only some of the embodiments of the present utility model, rather than all of them. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts fall within the protection scope of the present utility model.
[0019] The following will further describe the present utility model with reference to the accompanying drawings of the specification.
[0020] The present utility model provides the following technical solutions:
[0021] As shown in the Figures 1-3 accompanying drawings, the present utility model discloses a password disc brake lock, which includes a lock housing 1. The lock housing 1 has a lock core installation part 2 and a locking and positioning part 3. A locking hole 4 is provided on the locking and positioning part 3. A lock core 5 is arranged on the lock core installation part 2. The lock core 5 is movably arranged on the lock core installation part 2. An installation cavity 6 is formed inside the lock core installation part 2. A password component and a lock core transmission part 7 are arranged inside the installation cavity 6. The lock core transmission part 7 is movably arranged inside the installation cavity 6. One end of the lock core transmission part 7 extends out of the installation cavity 6 and is connected to the lock core 5. The lock core transmission part 7 limits the position of the lock core 5 on the lock core installation part 2. Specifically, in this design, by setting the password component and the lock core transmission part 7, the limiting structure of the password component can limit the movement of the lock core transmission part 7 inside the installation cavity 6. When locking is required, the lock core 5 is pressed, so that the bottom end of the lock core 5 extends into the locking hole 4 on the locking and positioning part 3. At this time, the lock core transmission part 7 moves towards the lock core 5 under the action of the first return spring 17, so that the lock core limiting part on the lock core transmission part 7 extends into the limiting groove 23 on the lock core 5 for locking. When unlocking is required, the push button part 11 on the lock core transmission part 7 is pushed in a direction away from the lock core 5, so that the limiting part disengages from the limiting groove 23. Subsequently, the lock core 5 pops out of the locking hole 4 under the action of the second return spring 20. This design has a simple structure, convenient unlocking and locking operations, and high security.
[0022] Specifically, the password component is a password wheel 8 and a password disc 9 in the prior art, so it will not be elaborated here. In this embodiment, the limiting pressing piece 24 is arranged on one side of the password disc 9 close to the lock core transmission part 7. The limiting pressing piece 24 is integrally formed with the password disc 9. When the password on the password component is incorrect, the limiting pressing piece 24 on the password component will abut against the body part 12 of the lock core transmission part 7, so that the lock core transmission part 7 cannot move towards the side away from the lock core 5. When the password is correct, the limiting pressing piece 24 will disengage from the body part 12 of the lock core transmission part 7 and will not hinder the lock core transmission part 7, enabling it to move freely. Such a setting ensures that the unlocking operation can only be performed when the correct password is input.
[0023] Furthermore, the lock core transmission member 7 has a lock core limiting portion 10, a push button portion 11 and a body portion 12. The password assembly further includes a positioning housing 15. The positioning housing 15 is provided with a sliding groove 13. The body portion 12 extends into the sliding groove 13 and is slidably connected to the password assembly. A push button hole 14 communicating with the installation cavity 6 is formed in the lock core installation portion 2. The push button portion 11 extends out of the installation cavity 6 through the push button hole 14. Pushing the push button portion 11 drives the lock core transmission member 7 to move in the sliding groove 13. The lock core limiting portion 10 protrudes from the body portion 12 of the lock core towards the lock core 5. Specifically, in this embodiment, the shape and size of the lock core limiting portion 10 match the limiting groove 23 on the lock core 5. When the lock core transmission member 7 moves in the sliding groove 13, the lock core limiting portion 10 can accurately insert into or disengage from the limiting groove 23, thereby realizing the locking and unlocking of the lock core 5. To improve the convenience of operation, the push button portion 11 is designed into a shape that is easy to operate by hand, such as a cylindrical shape or an elliptical shape, so that the user can easily push the push button portion 11 to perform the unlocking or locking operation.
[0024] Furthermore, a spring positioning end 16 protrudes from one end of the body portion 12 away from the limiting portion. A first return spring 17 is sleeved on the spring positioning end 16. Two ends of the first return spring 17 respectively abut against a portion of the body portion 12 close to the spring positioning end 16 and the inner wall of the installation cavity 6. Specifically, in this embodiment, the function of the first return spring 17 is to ensure that the lock core transmission member 7 can automatically reset when not acted upon by an external force, thereby keeping the lock core 5 in the locked state. When the user presses the lock core 5 to perform the unlocking operation, the first return spring 17 will be compressed. When the user releases the lock core 5, the first return spring 17 will push the lock core transmission member 7 back to the initial position, ensuring that the lock core 5 is inserted into the locking hole 4 again.
[0025] Furthermore, a lock core activity groove 18 is formed in the lock core installation portion 2. The lock core 5 is arranged in the lock core activity groove 18. A communication port 19 communicating with the installation cavity 6 is formed in the groove wall of the lock core activity groove 18. The lock core limiting portion 10 of the lock core transmission member 7 extends into the lock core activity groove 18 through the communication port 19 and is in limit connection with the lock core 5. Specifically, in this embodiment, the design of the lock core activity groove 18 enables the lock core 5 to move freely therein without excessive frictional resistance. The setting of the communication port 19 ensures that the lock core limiting portion 10 of the lock core transmission member 7 can be closely matched with the lock core limiting portion 10, thereby realizing precise locking and unlocking actions.
[0026] Further, a second return spring 20 is disposed in the lock core moving slot 18. The lock core 5 has a locking end 21 and a pressing end 22. The two ends of the second return spring 20 respectively abut against the bottom inner wall of the lock core moving slot 18 and the bottom of the pressing end 22. Specifically, in this embodiment, the function of the second return spring 20 is to ensure that the lock core 5 can automatically reset when not subjected to external force, so as to keep the lock core 5 in an unlocked state. When the user presses the lock core 5 for the locking operation, the second return spring 20 will be compressed. When the user releases the lock core 5, the second return spring 20 will push the lock core 5 back to the initial position, ensuring that the pressing end 22 of the lock core 5 is away from the locking hole 4, facilitating the locking operation again.
[0027] The above description of the disclosed embodiments enables those skilled in the art to implement or use the present invention. Various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein can be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention will not be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
