Technical Field

[0001] This utility model relates to the field of door lock technology, specifically to a reversible clutch assembly for a thermal break lock. Background Technology

[0002] Currently, once the clutch of a thermal break lock is installed, the steering cannot be changed at will. This defect leads to inconvenience in use and inconvenience after the handle is installed and glued. Summary of the Invention

[0003] The purpose of this utility model is to address the defects and shortcomings of the existing technology by providing a reversible clutch assembly for a bridge lock. This assembly facilitates the change of rotation direction, improves ease of use, and allows for easy application of adhesive after the handle fixing screws are installed, avoiding the problem of handle loosening caused by secondary screw removal. Furthermore, the addition of a clutch return spring effectively ensures the horizontal and verticality of the clutch, guaranteeing the accuracy of unlocking each time.

[0004] To achieve the above objectives, this utility model adopts the following technical solution: It includes a clutch component, which is sleeved on the handle head. The handle head is installed with the handle after passing through the panel assembly using a handle fixing screw. A return spring washer and a clutch return spring are sleeved on the inner end of the clutch component. One side of the return spring washer and the two ends of the clutch return spring are both locked on the locking post on the clutch component. The two ends of the clutch return spring are also locked on the clutch return spring fixing buckle on the front of the base plate. A square core passes through the clutch return spring and the return spring washer and is inserted into the clutch component and the handle head. A reversing screw is installed in the threaded post on the handle head. The end cap of the reversing screw is movably disposed on the outer edge of the clutch component and is movably abutting against the arc-shaped limiting edges on both sides of the outer edge.

[0005] Furthermore, the locking post is movably disposed in an arc-shaped groove formed on the base plate.

[0006] Furthermore, a clutch pin is installed on the clutch component using a clutch pin return spring. One end of the clutch pin passes through a groove on the inner end ring wall of the handle head, and the other end abuts against the arc-shaped plate of the motor output end installed in the panel assembly.

[0007] Furthermore, the base plate is mounted on the back of the panel assembly, and the handle is rotatably mounted in the panel assembly.

[0008] Furthermore, a handle torsion spring is sleeved on the connection end between the handle head and the handle. One end of the handle torsion spring abuts against the torsion spring limiting block on the handle head ring wall, and the other end abuts against the limiting block on the inner wall of the panel assembly.

[0009] Compared with the prior art, the beneficial effects of this utility model are: This utility model provides a reversible clutch assembly for a broken bridge lock, which facilitates the change of rotation direction, improves ease of use, and makes it easy to apply glue after the handle fixing screws are installed, avoiding the problem of handle loosening caused by secondary screw disassembly. In addition, a clutch return spring is added to effectively ensure the horizontal and verticality of the clutch, ensuring the accuracy of unlocking each time. Attached Figure Description

[0015] The technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings. The preferred embodiments described are only examples. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0016] like Figures 1-4As shown, this specific embodiment adopts the following technical solution: It includes a clutch 13, which is sleeved on the handle head 4. The handle head 4 is installed with the handle 1 after passing through the panel assembly 2 using a handle fixing screw 14. A handle torsion spring 3 is sleeved on the connection end between the handle head 4 and the handle 1. One end of the handle torsion spring 3 abuts against the torsion spring limiting block 4-1 on the annular wall of the handle head 4, and the other end abuts against the limiting block on the inner wall of the panel assembly 2. A return spring washer 12 and a clutch return spring 11 are sleeved on the inner end of the clutch 13. One side of the return spring washer 12 and the two ends of the clutch return spring 11 are both locked on the locking post 13-1 on the clutch 13. The locking post 13-1 is movably disposed in the arc-shaped groove 9-2 opened on the base plate 9. The two ends of the spring 11 are also secured to the clutch return spring fixing buckle 9-1 on the front of the base plate 9; the base plate 9 is installed on the back of the panel assembly 2, and the handle 1 is rotatably installed in the panel assembly 2; the square core 10 passes through the clutch return spring 11 and the return spring washer 12, and is inserted into the clutch 13 and the handle head 4; a reversing screw 5 is installed in the threaded post on the handle head 4, and the end cap of the reversing screw 5 is movably set on the outer edge of the clutch 13, and is movably abutting against the arc-shaped limiting edge 13-2 on both sides of the outer edge; a clutch pin 7 is installed on the clutch 13 by means of a clutch pin return spring 8, one end of the clutch pin 7 passes through the groove 4-2 on the inner end ring wall of the handle head 4, and the other end abuts against the arc-shaped plate of the output end of the motor 6 installed in the panel assembly 2.

[0017] In this invention, during the reversing operation, remove the reversing screw 5, rotate the handle 1 downwards by 180 degrees, and then install the reversing screw 5 back into the threaded post on the handle head 4 and tighten it.

[0018] In this utility model, when the handle 1 is lifted up during the reverse locking operation, the reversing screw 5 is pressed down and the clutch 13 rotates, which in turn rotates the lock body through the square core 10, causing the square tongue to pop out.

[0019] When this utility model is used for unlocking, it unlocks the door by using a valid password, fingerprint, or card information. Upon receiving the instruction, the module will supply power to the motor 6 correctly. The arc-shaped plate on the output end of the motor 6 will push out, thereby pushing the clutch pin 7 through the groove 4-2 on the handle head 4. This makes the handle 1, handle head 4, and clutch 13 fixed together in the same direction. Pressing down on the handle 1 rotates the lock body, and the square core 10 rotates the lock body. The square tongue retracts into the lock body, achieving the door opening effect.

[0020] Compared with the prior art, the beneficial effects of this utility model are: This utility model provides a reversible clutch assembly for a broken bridge lock, which facilitates the change of rotation direction, improves ease of use, and makes it easy to apply glue after the handle fixing screws are installed, avoiding the problem of handle loosening caused by secondary screw disassembly. In addition, a clutch return spring is added to effectively ensure the horizontal and verticality of the clutch, ensuring the accuracy of unlocking each time.

[0021] For those skilled in the art, modifications can be made to the technical solutions described in the foregoing embodiments, and equivalent substitutions can be made to some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
