[0029] Please refer to Figures 1 to 4, the special buckle for the metal belt lock of this embodiment includes: a female buckle 1, a male buckle 2, a group of switches 3 and a lock core module 4. Among them, the switch 3 is rotatably installed at one end of the male buckle 2 around a connection point, and clamping grooves 11 for clamping the switch 3 are formed on both sides of the female buckle 1. Pressing the switches 3 towards each other compresses the elastic member at the connection point and disengages the clamping connection between the switch 3 and the clamping groove 11. The lock core module 4 is installed in the female buckle 1, and a lock core 41 is installed on the lock core module 4, and a retaining ring 42 that rotates to a corresponding position in linkage with the lock core 41 and limits the opposite movement of the switch 3 or moves away from the switch 3 correspondingly.

[0030] In a preferred embodiment, a lock core fixing groove 12 is formed on the female buckle 1 between the two clamping grooves 11, and a protruding plate 13 protrudes from the lock core fixing groove 12 to form a group of clamping and fixing buckle grooves 14. Specifically, the lock core module 4 is installed in the lock core fixing groove 12 and is positioned by the protruding plate 13 and the clamping fixing groove 14.

[0031] The elastic member installed at the connection between the male buckle 2 and the switch 3 is a compression spring, and a mounting groove is recessed inward on the side of the male buckle 2 facing the female buckle 1. Mounting holes for cooperating with the switch 3 to install the elastic member are formed at the left and right ends of the mounting groove, and a limiting post for limiting the switch 3 protrudes in the mounting groove. Using a compression spring to replace the torsion spring in the prior art effectively improves the service life of the product.

[0032] Each switch 3 is in an L shape, and a second mounting hole for cooperating with the mounting hole is formed at the bent portion of each switch. When each switch 3 is inserted into the mounting groove, the mounting hole overlaps with the second mounting hole, and the elastic member is installed in the mounting hole and the second mounting hole. When pressing the two switches 3 towards each other on the side located in the clamping groove 11, when the protruding post protruding from the upper side of each switch 3 located on the mounting groove moves towards the limiting post and is compressed to a certain extent, the protruding post abuts against the limiting post. At this time, pulling the male buckle 2 towards the female buckle 1 can disengage the switch 3 from the clamping connection with the female buckle 1.

[0033] The lock core 41 is installed on the female buckle 1 through the lock hole 43, and the fixing member 44 passes through the retaining ring 42 and the lock hole 43 in sequence and is connected to the lock core 41. A set of baffles 421 for locking / releasing the switch 3 is formed on the retaining ring 42, and a receiving groove a1 is formed from one side to the other side of the lock hole 43. The lock core 41 is installed in the receiving groove a1, and a buckle a2 is formed on the lock hole 43 with a gap between the receiving groove a1; during assembly, the buckle a2 is stretched and fixed in the engaging and fixing groove 14 of the female buckle 1. A plurality of positioning columns a3 are convexly provided at the bottom end of the lock hole 43 to position the baffle 421 to rotate to the corresponding position. Specifically, when the retaining ring 42 rotates in conjunction with the lock core 41, the positioning column 43 positions the baffle 421 at a position that limits the switch 3 or is away from the switch 3, so that the switch 3 can be better engaged with the card slot 11 or disengaged from the card slot 11. Further, the retaining ring 42 is a circular structure with a card hole for engaging the lock core 41 formed in the center, and the baffles 421 extend from the edge of the retaining ring to the outside and extend toward the upper end of the lock core 41 with a gap between the lock hole 43. Each baffle 421 is L-shaped, and the baffles 421 are formed on the retaining ring 42 in an axisymmetric manner, and a group of unlocking and anti-loosening bayonet b1 is formed at a group of diagonal portions formed by the retaining ring 42 and the baffle 421, and a retaining ring buckle bayonet b2 is formed at at least one angle on the other diagonal portion. Furthermore, when the baffles 421 are facing the switches 3 respectively, the two positioning posts a3 are correspondingly engaged with the unlocking and anti-loosening bayonet b1. This design enables the product to have an anti-loosening effect. The other positioning post a3 is located on one side of the connecting center line of the baffles 421, specifically on the side where the retaining ring buckle bayonet b2 is formed. When the retaining ring 42 rotates, the positioning post a3 is engaged with the retaining ring buckle bayonet b2 to prevent the product from twisting with bare hands during use. More specifically, the fixing member 44 is a screw, and the lock core 41 includes: a lock core body used in conjunction with a key, a protruding engaging portion convexly provided at one end of the lock core body, engaged with the retaining ring 42 and driving the retaining ring 42 to rotate. During assembly, the protruding engaging portion penetrates the retaining ring 42 and is fixedly engaged with the screw. In a preferred embodiment, the lock core body is square-shaped, and a matching square key can be inserted into the lock core body and drive the retaining ring 42 to rotate.

[0034] From the above description, it can be seen that the utility model is equipped with the lock core assembly 4, and the switch 3 and the female buckle 1 are fixed and separated by the key, which improves the reliability of the product. In addition, the structural setting of the retaining ring 42 and the baffle 421, in conjunction with the fixing column a3, enables the product to have a better anti-loosening effect when in use, and avoids the defect of unscrewing the lock core 41 with bare hands. The utility model has a simple structural design and effectively improves the safety factor of the special environment.
