Description
Technical Field
[0001] The utility model relates to the technical field of watch hardware buckles, in particular to a hardware buckle with a self-locking structure. Background Art
[0002] In order to fix the watch on the wrist, a watch hardware buckle is needed. The watch strap passes through the hardware buckle seat, the hardware buckle teeth pass through the round holes of the watch strap, and the hardware buckle teeth are connected to the inner wall of the hardware buckle seat to fix the watch on the wrist and adjust the tightness of the watch. The existing hardware buckle seat and the hardware buckle seat are rotatably connected and do not have a self-locking function. When the watch is worn, the watch buckle teeth are easily scraped against clothes, causing the hardware buckle teeth and the hardware buckle seat to separate, and the watch becomes loose, causing the watch to fall, thereby reducing the practical performance of the watch hardware buckle.

When the watch is worn, the rotating rod 2 is rotated, the hardware buckle tooth body 3 enters the inner wall of the rectangular groove of the hardware buckle seat body 1, and the pressing block 5 enters the inner wall of the circular hole of the hardware buckle seat body 1. The limiting block 4 enters the inner wall of the pressing block 5 to lock the rotating rod 2, ensuring that the rotating rod 2 cannot continue to rotate, thereby adding self-locking performance to the watch hardware buckle.
[0022] Example 1:
[0023] In the specific implementation process, Figure 3 As shown, the inner walls of the limit block 4 and the pressing block 5 are shaped like an equilateral hexagon, and the inner wall diameter of the pressing block 5 is larger than the diameter of the limit block 4. When the limit block 4 enters the inner wall of the pressing block 5, the rotating rod 2 cannot rotate. The equilateral hexagonal structure is stable, and when the pressing block 5 is squeezed, the inner wall of the pressing block 5 will not be easily deformed.

Then, the driving block 11 is pulled. When the buckle rod 10 is close to the inner wall deep in the buckle groove 9, the extrusion sleeve 12 squeezes the buckle block 14 into the inner wall of the spring groove 13, which makes it convenient to pull the driving block 11, drive the buckle rod 10 to enter the buckle groove 9 away from the inner wall of the spring groove 13, and facilitate the hardware buckle tooth body 3 to move out of the rectangular groove of the hardware buckle seat body 1, again adding a self-locking structure to the watch hardware buckle.
