DETAILED DESCRIPTION

[0031] The technical solution of the utility model is further explained below with reference to the accompanying drawings and through specific implementation methods.

[0032] like Figures 1 to 12 As shown, the combination lock unlocking device provided in this embodiment includes an unlocking piece 1 and a combination disk lock 2. The unlocking piece 1 is similar to a door key without teeth. When it is inserted into the door lock, the door lock can be opened, that is, the unlocking piece 1 needs to be moved to unlock. At this time, if the movement of the unlocking piece 1 needs to be performed when the mechanical password is correct, that is, the mechanical password can be regarded as teeth, so as to achieve the purpose of unlocking only when the password is entered. The combination disk lock 2 includes a dial 21, an encryptor 22 and a rotating shaft 23, wherein the dial 21 has a number of numbers, and the user can select a suitable unlocking password to unlock by rotating the dial 21. For example, if 336699 is the unlocking password, then 3 rotations will unlock the door. Unlocking can be achieved by turning the dial 21 to position 33, position 66, and position 99. The dial 21 is fixed to one end of the rotating shaft 23, the unlocking piece 1 is fixed to the other end of the rotating shaft 23, and the encryptor 22 is sleeved on the rotating shaft 23. Specifically, most of the structure of the encryptor 22 is sleeved on the shaft sleeve 24 described below. The encryptor 22 can rotate relative to the rotating shaft 23, that is, when the dial 21 rotates, the encryptor 22 will be driven to unlock through the rotating shaft 23, so that the dial 21 of the combination disk lock 2 drives the encryptor 22 to rotate through the rotating shaft 23, realizing the function of locking with a mechanical structure and unlocking by entering a password. When the encryptor 22 rotates to the unlocking position, the unlocking piece 1 can be moved to unlock. The combination of the combination disk lock 2 and the unlocking piece 1 provided in this embodiment is equivalent to having an extra spare key, which completely solves the problem of being unable to unlock due to failure of the smart lock, loss of the key, etc.

[0033] In order to allow relative movement between the encryptor 22 and the rotating shaft 23 to facilitate the movement of the unlocking piece 1, the combination disk lock 2 further includes a sleeve 24, which is rotatably connected to the rotating shaft 23. A part of the encryptor 22 is fixed on the sleeve 24, and the sleeve 24 is fixedly connected to the fixing seat 4 by a screw passing through the arc hole 243 described below, that is, it will not perform telescopic movement with the rotating shaft 23. The rotating shaft 2 can not only rotate relative to the sleeve 24 following the rotation of the dial 21, but also when the dial 21 is pressed, the rotating shaft 2 will also follow the pressing action of the dial 21 and perform telescopic movement relative to the sleeve 24.

[0034] The combination lock unlocking device also includes a spring 3 for supporting the encryptor 22. The spring 3 is sleeved on the sleeve 24. One end of the spring 3 is against the baffle 244 at one end of the sleeve 24, and the other end of the spring 3 is against one side of the encryptor 22. Specifically, the spring 3 is against the gasket 228. The setting of the spring 3 makes the encryptor 22 always under pressure and against the retaining spring 6 to be limited. The other side of the encryptor 22 is against the retaining spring 6, and the retaining spring 6 is clamped on the other end of the sleeve 24. This setting method can reduce the difficulty of assembly. Under the action of the restoring force of the spring 3, the two ends of the encryptor 22 are limited and can move slightly, which is more suitable for unlocking.

[0035] The encryptor 22 includes a dial 221 and at least one cipher disk 222 adapted to the dial 221. Generally, there are preferably two cipher disks 222, so as to form three groups of ciphers together with the dial 221. When the cipher is required to be complex, more than three cipher disks 222 may be provided; when the cipher is required to be simple, one cipher disk 222 may be provided to achieve simple encryption. The dial 221 is fixed at the other end of the rotating shaft 23, close to the unlocking plate 1. At least one cipher disk 222 The dial 221 is sleeved on the shaft sleeve 24 and can rotate relative to the shaft sleeve 24. A fixing hole 226 is provided in the middle of the dial 221 to facilitate the fixing of the dial 221 on the rotating shaft 23. The dial 221 is provided with at least one round hole 227. When there are multiple round holes 227, the round holes 227 are distributed along the circumference of the dial 221. The round holes 227 can be used to install the lever and can also be used to return the dial 221 and the password disk 222 to facilitate setting different passwords. Preferably, a special lever can be provided on the dial 221, or a screw can be screwed into the round hole 227 to serve as the lever. A code disc protrusion 223 is provided on one or both sides of the code disc 222, and a code disc through hole 224 is provided in the middle of the code disc 222, so that the code disc 222 can be sleeved on the shaft sleeve 24 and can rotate relative to the shaft sleeve 24. An unlocking notch 225 is provided at the edge of the code disc through hole 224. When the unlocking notches 225 on multiple code discs 222 are aligned, the latch 25 can move, unlock the pressing action of the scale plate 21, and then make the rotating shaft 23 perform telescopic movement. The code disc protrusion 223 provided on the code disc 222 can be toggled by the lever, and when the code disc protrusion 223 is toggled by the lever, it will drive the adjacent code disc 222 to rotate. When a code disc 222 rotates, it will drive another adjacent code disc 222 to rotate. When all code discs 222 are rotated to the unlocking position, the unlocking notches 225 are aligned. In order to better axially position the code disk 222 and prevent it from shifting, the encryptor 22 also includes a gasket 228. At least one code disk 222 is sleeved on the shaft sleeve 24 through the gasket 228. A gasket through hole 229 adapted to the shaft sleeve 24 is provided in the middle of the gasket 228. The gasket through hole 229 is adapted to the shaft sleeve 24. A gasket protrusion 230 adapted to the first groove 241 of the shaft sleeve 24 is provided on the inner side of the gasket through hole 229. The gasket protrusion 230 can limit the rotation of the gasket 228 and improve the stability of the gasket 228. A gasket notch 240 is provided on the inner side of the gasket through hole 229. The gasket notch 240 can allow the pin 25 to pass through when it is displaced.

[0036] The combination lock unlocking device also includes a pin 25 that is compatible with the second groove 242 of the sleeve 24. The shape of the pin 25 is compatible with the shape of the unlocking notch 225 of the combination disk 222. Since the present application has two combination disks 222, the corresponding pin 25 also has two grooves to facilitate the rotation of the combination disk 222. When the unlocking notches 225 of the two combination disks 222 are aligned, the pin 25 can follow the rotating shaft 23 to perform telescopic movement.

[0037] In order to fix the combination disk lock 2, the combination lock unlocking device further includes a fixing base 4 for fixing the combination disk lock 2, one end of the fixing base 4 has a first cavity 41 for accommodating the dial 21, and the other end of the fixing base 4 has a second cavity 42 for accommodating the encryptor 22. The rotating shaft 23 passes through the middle of the fixing base 4. By setting the first cavity 41 and the second cavity 42, the dial 21 and the encryptor 22 can be protected respectively and the two can be isolated to prevent violent decryption without entering the password.

[0038] The password lock unlocking device also includes a cover body 5, which is detachably connected to the outer wall of the first cavity 41. The cover body 5 can protect the dial 21 from dust and dirt. One end of the sleeve 24 has a baffle 244, and the baffle 244 has at least one arc hole 243. The sleeve 24 is fixedly connected to the fixing seat 4 by at least one screw passing through the arc hole 243. The arc hole 243 can adjust the installation angle of the sleeve 24. Different adjustment angles of the installation of the sleeve 24 will cause the reference of the password setting to be changed so as to set a suitable password.

[0039] In specific use, the number of the combination disks 222 is preferably two. When emergency unlocking is required, the dial 21 is rotated. When the dial 21 rotates clockwise or counterclockwise, the rotating shaft 23 drives the dial 221 to rotate clockwise or counterclockwise. When the dial 221 rotates, the screw on it pushes the code disk protrusion 223 on the combination disk 222 to rotate. Since at least part of the code disks 222 have code disk protrusions 223 on both sides, when a certain code disk 222 is rotated, it will drive the next adjacent code disk 222 to rotate until the dial 21 rotates clockwise or counterclockwise to the first correct unlocking position. Align the unlocking notch 225 of the code disk 222 away from the dial 221 with the latch 25, stop rotating clockwise or counterclockwise at this time, and then rotate the dial 21 in the opposite direction to rotate the other code disk 222 to the correct unlocking position, and similarly align the unlocking notch 225 of the other code disk 222 with the latch 25. When the unlocking notches 225 of the code disk 222 are all aligned with the latch 25, the shaft 23 can be pushed, that is, press the dial 21, and the latch 25 will move along the axial direction of the shaft 23 together, and the unlocking piece 1 can be inserted into the lock core hole, and then rotate the dial 21 to open the door lock. After opening the door lock, pull out the dial 21, and then return the dial 21 to complete the unlocking.
