[0027] The preferred embodiments of this utility model will be described in detail with reference to the accompanying drawings.

[0028] Figures 1 to 10 This invention provides a preferred embodiment of an anti-theft fingerprint lock. For example... Figures 1 to 10As shown, this anti-theft fingerprint lock is located at the locking position of a bag, including a housing 10 for mounting on the outside of the bag and a base 20 for mounting on the inside of the bag. The base 20 has a locking slot 21 for inserting a locking hook 100 from the bag. A locking tongue rotating seat 22 is mounted inside the locking slot 21 via a pin 2201. One side of the locking tongue rotating seat 22 has a locking tongue hook 221 for engaging with the bag's locking hook 100, and the other side has an extension arm 222. The extension arm 22 is supported by a sliding seat 23, which has an unlocking port 231. The base 20 also has a motor 30 for moving the unlocking port 231 on the sliding seat 23 to below the extension arm 22 for insertion and unlocking. The housing 10 has a fingerprint recognition module 11, which is connected to a main control circuit board 12, which is connected to the motor 30. When locked, if... Figure 7 and Figure 8 As shown, the bag lock hook 100 is inserted into the lock opening 21. The bag lock hook 100 presses down on the lock tongue hook 221, and the lock tongue rotating seat 22 rotates around the pin 2201, causing the extension arm 222 to lift up, releasing the bag lock hook 100. The translation seat 23 supports the falling extension arm 222, thus keeping the lock tongue hook 221 hooked on the bag lock hook 100, forming a locked state; while unlocking, as Figure 9 and Figure 10 As shown, after the fingerprint recognition module 11 reads the preset fingerprint, the motor 30 starts. The motor 30 drives the unlocking port 231 on the sliding base 23 to move below the extension arm 222. The extension arm 222 falls into the unlocking port 231, and the lock tongue rotating base 22 rotates around the pin 25, causing the lock tongue hook 221 to lift up and separate from the bag lock hook 100, thereby preventing the bag from being opened arbitrarily and greatly protecting the user's privacy and security. There is no need to remember complex passwords or carry spare keys. It is simple and convenient, and can replace traditional zipper locks. It is compatible with mainstream bag sizes and does not require customization. The outer shell 10 and the base 20 are installed on the bag with screws. The bag lock hook 100 can be set at the bottom of the zipper on the bag or on the back of the bag flap, depending on the needs. The entire anti-theft fingerprint lock can be used on suitcases, backpacks, or handbags, bringing convenience to users' daily travel.

[0029] The motor shaft of the motor 30 drives the rotating disk 31 to rotate. The rotating disk 31 is provided with an eccentric shaft 32 for driving the moving seat 23 to move. The moving seat 23 is provided with a boss 232 that cooperates with the eccentric shaft 32. The boss 232 is located on the rear side of the moving seat 23, and the unlocking port 231 is located on the front side of the moving seat. In this way, when the motor 30 drives the rotating disk 31 to rotate, the eccentric shaft 32 performs an eccentric movement. By cooperating with the boss 232, the eccentric shaft 32 can push the moving seat 23 to move, so that the moving unlocking port 231 on the moving seat 23 moves to below the extension arm 222. The extension arm 222 can fall into the unlocking port 231, thereby causing the locking tongue hook 221 to lift up and the locking tongue hook 221 to separate from the bag lock hook 100.

[0030] like Figure 5 As shown, the base 20 has a groove 24 for sliding the translation seat 23. The groove 24 is provided with a return spring 233 connected to the translation seat 23. The translation seat 23 is in the groove 24. The motor 30 drives the boss 232 through the eccentric shaft 32, thereby realizing the linear movement of the translation seat 23. When there is no motor 30 and the extension arm 222 is outside the unlocking port 231, the translation seat 23 can return to its original position under the action of the return spring 233.

[0031] The base 20 has a latch groove 25 for housing the latch rotating seat. The latch rotating seat 22 is installed in the latch groove 25 via a pin 2201. The front side of the latch groove 25 communicates with the lock opening 21, and the rear side of the latch groove 25 forms a movable groove 251 between it and the slide groove 24 for the extension arm to move up and down. Thus, when locking, the bag lock hook 100 presses down on the latch hook 221 located in the lock opening 21, and the extension arm 222 tilts up in the movable groove 251, causing the translation seat 23 to... The return spring 233 resets the position, and the translation seat 23 supports the falling extension arm 222. When unlocking, the motor 30 uses the eccentric shaft 32 to cooperate with the boss 232 to drive the translation seat 23 to move. The unlocking port 231 on the translation seat 23 moves to align with the movable groove 251 and is directly below the extension arm 222. The extension arm 222 falls, causing the locking hook 221 to lift up. The hook of the locking hook 221 faces upward, and the locking hook 221 can be separated from the bag lock hook 100 at will.

[0032] like Figure 4 As shown, a torsion spring 2202 for resetting the latch rotating seat 22 is also fitted on the pin 2201. The torsion spring 2202 is placed in the torsion spring groove 223 on the side of the latch rotating seat 22. Under the action of the torsion spring 2202, the extension arm 222 on the latch rotating seat 22 can be driven to fall, thereby raising the latch hook 221. When the latch hook 221 is separated from the bag lock hook 100, the bag lock hook 100 is automatically lifted up, providing convenience for the user.

[0033] The base 20 also has a motor slot 26 for mounting the motor 30. A communication port 261 is provided between the sliding groove 24 and the motor slot 26. The boss 232 and the eccentric shaft 32 are located in the communication port 261, so that the motor 30 drives the eccentric shaft 32 to rotate, thereby driving the translation seat 23 to move.

[0034] The base 20 includes a seat body 201 and a base plate 202 disposed at the bottom of the seat body. The locking tongue groove 25, the sliding groove 24, and the motor groove 26 are all disposed within the seat body 201. The base plate 202 has a motor position corresponding to the motor groove 26, thereby positioning the motor 30 and preventing the motor 30 from shifting arbitrarily. The seat body 201 and the base plate 202 adopt a split design for easy assembly.

[0035] The outer casing 10 has a through-hole 13 corresponding to the lock slot 21. The main control circuit board 12 is connected to an indicator light and a power supply, which is located inside the casing. The main control circuit board 12 is also connected to an unlocking and charging interface 14. When the fingerprint fails or in an emergency, the unlocking and charging interface 14 can be used to connect to a corresponding external device for unlocking, which is simple and convenient. Furthermore, when the unlocking and charging interface 14 is connected to a power source, it can also be used as a charging interface. In one embodiment, the unlocking interface is a USB interface for use with an unlocking key, which the user can store elsewhere for backup.

[0036] The entire process of using the anti-theft fingerprint lock is as follows: (1) When locking, if Figure 7 and Figure 8 As shown, the bag lock hook 100 is inserted into the lock opening 21. The bag lock hook 100 presses down on the lock tongue hook 221. The lock tongue rotating seat 22 rotates around the pin 2201, causing the extension arm 222 to lift up. Under the action of the return spring 233, the translation seat 23 returns to its original position. The unlocking port 231 on the translation seat 23 is misaligned with the extension arm 222. When the bag lock hook 100 is released, the translation seat 23 supports the falling extension arm 222, preventing the extension arm 222 from falling further and the lock tongue hook 221 from lifting up. This hooks the lock tongue hook 221 onto the bag lock hook 100, preventing the bag lock hook 100 from detaching arbitrarily. (2) When unlocking, as Figure 9 and Figure 10 As shown, after the fingerprint recognition module 11 reads the preset fingerprint, the motor 30 starts. The motor 30 drives the unlocking port 231 on the translation seat 23 to move to the bottom of the extension arm 222. The extension arm 222 falls into the unlocking port 231, and the lock tongue rotating seat 22 rotates around the pin 25, causing the lock tongue hook 221 to lift up with the hook opening facing upward, and the lock tongue hook 221 separates from the bag lock hook 100.

[0037] In summary, the technical solution of this utility model can fully and effectively achieve the aforementioned objectives. Furthermore, the structure and functional principles of this utility model have been fully verified in the embodiments, achieving the expected effects and objectives. Without departing from the principles and essence of this utility model, various changes or modifications can be made to the embodiments. Therefore, this utility model includes all substitutions within the scope mentioned in the patent application claims, and any equivalent changes made within the scope of this patent application are within the scope of the patent application.
