[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0018] Depend on Figures 1 to 5 The present invention includes a lock head 1 and a U-shaped lock rod 2. Both ends of the lock head 1 are provided with lock holes 3. The inner side of the two lock holes 3 that are close to each other is provided with an inner groove 4. The opposite ends of the two inner grooves 4 are provided with square inner cavities 5. An adjustable square hollow tube 6 is installed inside the square inner cavity 5. One end of the square hollow tube 6 is connected to an isosceles trapezoidal pin 7 that extends into the inner groove 4. The inner sides of both ends of the U-shaped lock rod 2 are provided with isosceles trapezoidal slots 8 that match the isosceles trapezoidal pins 7 at equal intervals. The bottom of the U-shaped lock rod 2 is provided with a lock cylinder 9 that is connected to one of the square hollow tubes 6. The U-shaped lock rod 2 is provided with a mounting cavity 10. A motor 11 that is connected to the other square hollow tube 6 is installed inside the mounting cavity 10.

[0019] Two square hollow tubes 6 are each movably connected to one end of a T-shaped pin 12. A spring A13 is fixedly connected between the inside of the square hollow tube 6 and one end of the T-shaped pin 12. The other end of the T-shaped pin 12 extends into the inside of the inner groove 4 and is fixedly connected to the isosceles trapezoidal pin 7, so that the U-shaped locking rod 2 can be effectively locked to the lock head 1. A U-shaped block 14 is fixedly installed at one end of the square hollow tube 6 inside the square inner cavity 5. A pressing plate 15 is fixedly connected to the middle of the U-shaped block 14. A spring B16 is fixedly connected between one end of the pressing plate 15 and one end of the square inner cavity 5, so that the isosceles trapezoidal pin 7 can be effectively reset.

[0020] The bottom of each of the two square hollow tubes 6 is provided with a groove 17, and a disc 18 is provided inside each of the two grooves 17. A toggle pin 19 is fixedly connected to the top edge of each disc 18. The two toggle pins 19 are located inside the two U-shaped blocks 14 respectively. The upper part of the lock cylinder 9 and the output end of the motor 11 are fixedly connected to the axis of the two discs 18 respectively, so as to effectively adjust the isosceles trapezoidal pin 7. A card reader controller 20 connected to the motor 11 is installed inside the mounting cavity 10. A rechargeable battery 21 connected to the motor 11 and the card reader controller 20 is installed inside the mounting cavity 10, so as to effectively control and adjust.

[0021] The key that matches the lock cylinder 9 in this lock contains an RFID chip with an identification code that matches the card reader controller 20; when the user inserts the key with the RFID chip into the lock cylinder 9 and turns to unlock it, the card reader controller 20 senses the identification code in the RFID chip and matches its internal information, and controls the motor 11 to rotate.

[0022] The rotation of the lock cylinder 9 and the motor 11 will drive the disc 18 to rotate. The rotation of the two discs 18 will drive the two U-shaped blocks 14 to move relative to each other through the two actuating pins 19. The relative movement of the U-shaped blocks 14 will drive the pressing plate 15 to compress the spring B16. At the same time, the relative movement of the U-shaped blocks 14 will drive the square hollow tube 6 to move. The movement of the square hollow tube 6 will drive the T-shaped pin 12 and the isosceles trapezoidal pin 7 to move, thereby causing the isosceles trapezoidal pin 7 to be withdrawn from the inside of the isosceles trapezoidal slot 8. At this time, the lock head 1 and the U-shaped lock rod 2 can be separated from the lock.

[0023] If either the key or the RFID chip in the key does not match the lock cylinder 9 or the card reader controller 20, the lock head 1 and the U-shaped locking rod 2 cannot be separated and locked.

[0024] This anti-theft lock features a dual anti-theft structure combining a mechanical lock cylinder and an electronic lock cylinder. Both cylinders must be opened simultaneously for the lock to be effectively opened; if either cylinder is opened, the lock cannot be opened. This effectively solves the problem of poor anti-theft performance with a single lock cylinder structure. Furthermore, this anti-theft lock has a simple design, is convenient and easy to use, and offers stable and reliable anti-theft protection, meeting the needs of users.
