[0002] With the continuous development of science and technology, intelligence and security have become the themes of people's research, especially how to improve the security of doors such as special counters, display cabinets, windows and smart home devices in the retail industry has become a hotly studied topic. Among them, electronic locks are more convenient to use than traditional mechanical locks, and have been greatly improved in both technology and performance. They have become more and more popular in recent years.

[0003] However, traditional electronic locks are large in size and are not suitable for installation environments of small objects. In actual use, the dust and moisture accumulated in the operating space for a long time produce complex physical and chemical reactions when the temperature changes, which affects the gear rack mechanism of the traditional electronic lock. In addition, the traditional electronic lock has poor anti-theft performance, posing a security risk to the user's finances. Summary of the invention

[0015] The technical solution of this patent is further described in detail below in conjunction with specific implementation methods.

[0016] See also Figure 1 A miniature smart lock with an anti-pry function comprises a lock shell 16 and a magnetic rod 8, a push head 9, a lock tongue 10, a V-shaped push rod 11, an anti-pry guide groove 12, and a positioning guide pin 14 installed in the lock shell 16. The net length of the lock shell 16 is 50-145 mm, the height is 14-28 mm, and the width is 14-20 mm. A lock plate 21 is installed at the bottom of the lock shell 16. A magnetic coil 7 is installed around the outside of the magnetic rod 8. A magnetic rod spring 6 is installed on the magnetic rod 8 on the left side of the magnetic coil 7. The push head 9 is installed at the right end of the magnetic rod 8. The V-shaped push rod 11 is connected to the right end of the push head through a V-shaped push rod connecting pin 17, and the V-shaped push rod 11 and the lock tongue 10 are slidably connected through an anti-pry pin 13, and the end of the anti-pry pin 13 after passing through the V-shaped push rod 11 and the lock tongue 10 is arranged in an anti-pry guide groove 12, and the anti-pry guide groove 12 is V-shaped, and the bottom transverse groove of the anti-pry guide groove 12 is parallel to the bottom of the lock shell, and the vertical groove extends obliquely toward the top of the lock shell, and the positioning guide pin 14 is connected to the right side of the lock tongue 10, and the lower part of the positioning guide pin 14 is equipped with a return spring 15 connected to the lock shell 16.

[0017] The working principle of the micro smart lock with anti-pry function is as follows:

[0018] When unlocking, the magnetic coil 7 is connected to the DC (8-12) V power supply to generate a magnetic field, causing the magnetic rod 8 to move rightward, and the linkage push head 9 pushes the V-shaped push rod 11, thereby driving the anti-pry pin 13 to slide horizontally to the right in the anti-pry guide groove 12 through the V-shaped push rod, and then move upward along the oblique part of the anti-pry guide groove 12, while driving the lock tongue 10 to lift upward. The power-on time of the magnetic coil 7 is 1-6 seconds (which can be adjusted through the supporting control software). If the power-on of the magnetic coil 7 is terminated, the magnetic field of the magnetic coil 7 disappears, and the lock tongue 10 moves downward through the reset spring 15, while driving the anti-pry pin 13 to move downward along the vertical part of the anti-pry guide groove 12 until the lock tongue 10 is reset and locked. While the reset spring 15 moves, the magnetic rod spring 6 drives the magnetic rod 8 and the push head 9, and the linked V-shaped push rod 11 moves to the left. At the same time, the V-shaped push rod 11 drives the anti-pry pin 13 to move to the left in the horizontal part of the anti-pry guide groove 12 to the far left, that is, the anti-pry pin 13 is reset. After the anti-pry pin 13 is reset, the lock tongue 10 cannot be lifted directly upward, thereby achieving the anti-pry function of the lock tongue.

[0019] The above describes in detail the preferred implementation of this patent, but this patent is not limited to the above implementation. Various changes can be made within the knowledge scope of ordinary technicians in this field without departing from the purpose of this patent.
