The dust cover 122 can prevent dust and debris from entering the inside of the lock core 150, keeping the lock core 150 clean and smooth, prolonging the service life of the lock core 150.
[0033] Referring to Figure 2 , a cover 500 is connected to the lock shell 200. The main function of the cover 500 is to close the opening 201 of the lock shell 200, preventing external objects from entering the inside of the lock shell 200. The cover 500 is designed with a clearance protrusion 510, and the midpoint of the protrusion has a through hole 511 which can accommodate the square iron, realizing the connection between the lock seat 400 and the square iron. The cover 500 not only closes the opening 201 of the lock shell 200, preventing the entry of external objects, but also realizes the connection between the lock seat 400 and the square iron through the through hole 511 of the clearance protrusion 510, improving the compactness and stability of the mechanism.
[0034] In order to improve the waterproof performance of the handle lock, a waterproof groove 210 is provided along the circumference of the opening 201 of the lock shell 200. A waterproof rubber ring 211 is embedded in the waterproof groove 210, effectively preventing water from seeping into the inside of the lock shell 200 from the opening 201. The design of the waterproof groove 210 and the waterproof rubber ring 211 improves the waterproof performance of the handle lock, enabling it to maintain a stable working state in a humid environment.
[0035] Referring to Figure 2It should be noted that the linkage seat 300 and the lock seat 400 are respectively provided with the first reset torsion spring 330 and the second reset torsion spring 420. The first reset torsion spring 330 is installed on the linkage seat 300, and both ends thereof are fixed on the linkage seat 300 and the corresponding position of the lock shell 200, respectively. When the linkage seat 300 is rotated under the action of external force, the first reset torsion spring 330 will be compressed or stretched to store elastic potential energy. Once the external force disappears, the first reset torsion spring 330 will release the stored elastic potential energy to automatically reset the linkage seat 300.
[0036] Similarly, the second reset torsion spring 420 is installed on the lock seat 400, and both ends thereof are fixed on the lock seat 400 and the corresponding position of the lock shell 200 or the linkage seat 300, respectively. When the lock seat 400 is rotated under the action of external force, such as being driven by the square iron to unlock the lock tongue, the second reset torsion spring 420 will also be compressed or stretched to store elastic potential energy. After unlocking is completed, the second reset torsion spring 420 releases the stored elastic potential energy to automatically reset the lock seat 400, ready for the next locking operation. By respectively providing the linkage seat 300 and the lock seat 400 with the first reset torsion spring 330 and the second reset torsion spring 420, it can be ensured that both of them can be quickly and stably reset after being subjected to external force. This design improves the reliability and durability of the handle lock.
