[0023] In specific implementation, a base bottom plate 20 is mounted on the outer side of the base body 10, a pushing block 21 is mounted in the base bottom plate 20, the reset core 16 is connected with the pushing block 21, in use, the connection between the pushing block 21 and the reset core 16 ensures the accurate movement of the reset core, the pushing block 21 can push the reset core 16 to move up and down during the unlocking process, helping the linkage wheel 15 and the gear system to correctly butt joint, the advantage of the design is that the movement of the reset core 16 is not hindered, reducing the situation of jamming or not smooth, ensuring the smoothness of the unlocking process.
[0024] In the specific implementation, the outer side of the base body 10 is provided with a face cover 30 and a rear cover 40, which are connected and fixed by fasteners. The lower part of the face cover 30 is connected with a door handle 31. The outer side of the door handle 31 is connected with a gasket 311. One side of the door handle 31 is connected with a handle seat 312. One side of the handle seat 312 is sequentially connected with a square hole component 32, a linkage gear 33, a clutch ring 34, a clutch block 35, and a reversing clutch block 36. A copper sleeve 37, a return gear 38, and a return shaft 39 are sequentially connected in the linkage gear 33, the clutch ring 34, the clutch block 35, and the reversing clutch block 36. In use, the user rotates the door handle 31. The door handle 31 cooperates with the handle seat 312 to drive the linkage gear 33 to rotate. The rotation of the linkage gear 33 is transmitted to the clutch ring 34 and the clutch block 35. The cooperation between the clutch ring 34 and the clutch block 35 allows the lock to enter the unlocking mode, allowing the subsequent lock body to be unlocked. During the unlocking process, the cooperation of the clutch ring 34 and the clutch block 35 controls the movement of the linkage gear 33, which ensures that the lock body can only be unlocked after the correct password is input. The reversing clutch block 36 ensures the correctness of the working direction of the lock, ensuring the accurate switching of the unlocking and locking states of the lock body. In the case of successful unlocking or password error, the return gear 38 and the return shaft 39 cooperate to complete the reset. The return gear 38 restores to the initial state by rotating the reset shaft 39, ensuring that the lock can start again at the next operation. In the case of normal cooperation of all linkage components, the cooperation of the return core, the linkage gear, the door handle, and the return gear will eventually drive the lock body to unlock. At this time, the door handle can be smoothly rotated, the lock body is released, and the door can be opened.
[0025] In the specific implementation, the surface of the face cover 30 is sequentially connected with a plurality of password keys 50. One end of each of the plurality of password keys 50 is connected with a password sheet 51. The outer side of each of the plurality of password sheets 51 is connected with a password sheet spring 511. When the user needs to input a password, the password key 50 is pressed. Each of the password keys 50 is connected with a corresponding password sheet 51. When the key is pressed, the password sheet 51 moves or rotates. These actions trigger the rotation of the password gear 14 and the linkage gear 33, and transmit the operation signal to the control system of the internal lock.
[0026] In the specific implementation, one end of the base body 10 is connected with a code changing column 17. In use, the code changing column 17 is a key component in the lock for changing the password combination. It recombines the password sheet 51 or the password gear 14 inside by rotating or displacing, thereby realizing the replacement or adjustment of the password.
[0027] In the specific implementation, the base plate 20 is connected with a rear side plate 22 and a front side plate 23 on both sides, the rear side plate 22 is sequentially connected with a wedge spring 24, a wedge 25 and a reset rod 26 on one side, the reset rod 26 is sequentially connected with a reset wheel 261, a plurality of password reset pieces 262 and a positioning piece pin 263 on the outer side, a plurality of the password reset pieces 262 are connected with reset piece springs 264 on one side, in use, when the user inputs the password, the wedge 25 interacts with other mechanical components inside the lock through the action of the wedge spring 24, so as to maintain the stability of the system. Once the password is input correctly, the cooperation of the wedge spring 24 and the wedge 25 ensures the movement of the reset rod 26, the movement of the reset rod 26 triggers the rotation of the reset wheel 261, the reset wheel 261 makes the password reset pieces 262 restore to their initial state one by one through linkage with the reset pieces, and the reset piece spring of each reset piece ensures its rapid rebound, avoiding long-time jamming or misoperation. In this process, the positioning piece pin ensures that the reset pieces can be accurately docked, so as to ensure that each reset piece can be restored at the correct position.
[0028] In the specific implementation, one end of the code changing main shaft 11 is connected with a code changing main shaft spring 111 and a code changing main shaft sleeve 112, in use, the user presses the code changing main shaft 11 to make the connected password gear 14 or password piece 51 displace, and adjust to a new password combination, once the password setting is completed, the code changing main shaft spring 111 will automatically reset the code changing main shaft 11 to the original position, ensuring that the password has been firmly fixed and ready for the next operation.
