The inner lock cylinder 110 is provided with a reset spring hole 116, and the inner wall of the reset spring hole 116 is equipped with a reset spring body 117.

[0024] Furthermore, such as Figure 2 and Figure 7 As shown, the inner wall of the mounting plate 104 is provided with an easy-installation mechanism 3. The easy-installation mechanism 3 includes a stabilizing suction cup 31, a holding groove 32, and an easy-installation assembly 33. The easy-installation assembly 33 is located on the inner wall of the mounting plate 104 and consists of a mounting block 331, a fixing plate 332, and a mounting slot 333. The inner wall of the mounting plate 104 is provided with a holding groove 32. The inner wall of the holding groove 32 is equipped with a fixing plate 332. The holding groove 32 is provided with a stabilizing suction cup 31 for preventing the mounting plate 104 from loosening. The stabilizing suction cup 31 is a high-strength suction cup. The surface of the stabilizing suction cup 31 is equipped with a mounting block 331. The inner wall of the fixing plate 332 is provided with a mounting slot 333. The mounting slot 333 and the surface of the mounting block 331 are engaged with each other.

[0025] In practice, the user places the stabilizing suction cups 31 inside the receiving slots 32, causing the stabilizing suction cups 31 to automatically engage with the mounting blocks 331 inside the corresponding mounting slots 333. Under the engaging action of the mounting blocks 331 and the mounting slots 333, the stabilizing suction cups 31 are installed inside the receiving slots 32. The receiving slots 32 inside the stabilizing suction cups 31 enhance the overall stability of the mounting plate 104 and the lock body 1 during installation and use, making it less prone to loosening. Subsequently, the user tightens the mounting screws 106 on the surface of the mounting plate 104, which, under the action of the mounting screws 106, installs the mounting plate 104 onto the surface of the cabinet, thereby installing the lock body 1 onto the surface of the cabinet for use, thus realizing the function of easy installation of the lock structure.

[0026] Furthermore, such as Figure 2 As shown, a high-security mechanism 2 is provided inside the lock body 1. The high-security mechanism 2 includes an RFID chip 21, a wireless power supply module 22, and a high-security group 23. The high-security group 23 is located inside the lock body 1 and consists of a reader 231 and a system memory 232. The RFID chip 21 is installed inside the lock body 1 and is located above the outer lock cylinder 105. The wireless power supply module 22 is installed inside the lock body 1 and is connected to the RFID chip 21. The reader 231 and the system memory 232 are installed on the inner wall of the lock body 1. The reader 231 and the system memory 232 are respectively connected to the RFID chip 21.

[0027] In practice, the RFID chip 21 inside the lock body 1 is a passive electronic tag that exchanges data via radio waves. The chip code value is read by the wireless power supply module 22 to determine identity. When a user approaches the lock body 1, the reader 231 inside the lock body 1 activates the RFID chip 21 via radio waves and reads its unique identifier. If the unique identifier matches a preset identifier in the system memory 232, the lock body 1 will automatically open. This unlocking method is convenient, fast, highly secure, and difficult to copy. If the unique identifier does not match the preset identifier in the system memory 232, the lock body 1 will not automatically open, thus achieving a high level of security for the lock structure.

[0028] Working principle: In use, first place the lock body 1 in the designated position on the cabinet. The user places the stabilizing suction cups 31 inside the receiving slots 32, causing the stabilizing suction cups 31 to automatically engage with the mounting blocks 331 in the corresponding mounting slots 333. Under the engaging action of the mounting blocks 331 and the mounting slots 333, the stabilizing suction cups 31 are installed inside the receiving slots 32. The receiving slots 32 inside the stabilizing suction cups 31 enhance the overall stability of the mounting plate 104 and the lock body 1 during installation and use, making it less prone to loosening. Subsequently, the user tightens the mounting screws 106 on the surface of the mounting plate 104. Under the action of the mounting screws 106, the mounting plate 104 is installed on the surface of the cabinet, thereby installing the lock body 1 on the surface of the cabinet for use. This achieves the function of easy installation of the lock structure, making it convenient for the user to install the lock body 1 in the designated position for use, while further improving the stability of the lock body 1 during installation and use.

[0029] Subsequently, the user inserts the key into the keyhole 103. When the key protrusion at the front end of the key is just inserted into the keyhole 103 of the actuating block body 115, the key can be turned, causing the actuating block body 115 to rotate. When the actuating block protrusion 111 of the actuating block body 115 rotates to the tumbler groove 114, the key is continued to be inserted inward, which pushes the actuating block body 115 inward. At this time, the actuating block body 115 compresses the return spring body 117 inside the return spring hole 116, thereby driving the comb-shaped anti-push plate 112 inward. At this time, the baffle of the tumbler groove 114... Located within the key tooth rotation groove 118, the pin assembly 113 is positioned within the key tooth rotation groove 118. At this time, the key teeth are in contact with the pin assembly 113, lifting the pin assembly 113. As rotation continues, the inner lock cylinder 110 can rotate relative to the lock body 1. The user can press the handle 102 on the surface of the fixed cover 101 to complete the unlocking action and perform mechanical unlocking. Pressing in the opposite direction will complete the locking action. At this time, under the elastic force of the extension spring 109, the locking piece 108 automatically engages with the surface of the actuating block body 115, preventing the lock body 1 from being opened.

[0030] Subsequently, the RFID chip 21 inside the lock body 1 is a passive electronic tag that can exchange data via radio waves. The chip code value can be read by the wireless power supply module 22 to determine identity. When a user approaches the lock body 1, the reader 231 inside the lock body 1 activates the RFID chip 21 via radio waves and reads its unique identifier. If the unique identifier matches a preset identifier in the system memory 232, the lock body 1 will automatically open. The advantages of this unlocking method are convenience, speed, high security, and difficulty in duplication. If the unique identifier does not match the preset identifier in the system memory 232, the lock body 1 will not automatically open, thus achieving a high-security function for the lock structure. This allows for quick unlocking without the need to carry a traditional key, while also retaining traditional unlocking methods for unforeseen circumstances, greatly improving the security of the lock structure and ultimately completing its operation.

[0031] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
