[0002] A belt buckle is a hardware accessory at the front end of a belt. It is used to fix one end of the belt and tighten the belt passing through the buckle to adjust the length of the belt to suit the needs of people with different waist sizes. It has been widely used in the clothing industry.

[0003] However, existing belt buckles cannot automatically adjust after being fastened. People's waist circumferences are different when sitting and standing, or when they are full and hungry. Especially for people with a belly, the belt will be particularly tight after sitting or having a full stomach, affecting the use. In public places, it is not allowed to unbuckle the belt after sitting or having a full stomach, because it is very impolite. Utility Model Content

When the user's waist circumference becomes larger, the retractable device can automatically increase the distance between the first seat body and the second seat body, thereby increasing the length of the belt to avoid the belt squeezing the user's waist and making the user feel uncomfortable. When the user's waist circumference becomes smaller, the retractable device can automatically reduce the distance between the first seat body and the second seat body, thereby reducing the length of the belt. Specifically, the retractable device includes a plug-in mechanism and a retractable mechanism. The plug-in mechanism is arranged between the first seat body and the second seat body to guide the second seat body to perform a retractable action. The retractable mechanism is arranged between the plug-in mechanism and the first seat body to push the second seat body back to its original position when the user's waist circumference becomes smaller.

[0019] The following will clearly and completely describe the technical solutions of the present invention in conjunction with the drawings in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts should fall within the scope of protection of the present invention.

[0020] Reference Figure 1-Figure 4 As shown, a retractable belt buckle includes a belt buckle body 1 and a connecting base 2. The connecting base 2 includes a first base 21 and a second base 22. The first base 21 is rotatably connected to the belt buckle body 1. A retractable device 3 is provided between the first base 21 and the second base 22. The retractable device 3 can adaptively adjust the distance between the first base 21 and the second base 22. When the user's waist circumference becomes larger, the retractable device 3 can automatically increase the distance between the first base 21 and the second base 22, thereby increasing the length of the belt and preventing the belt from strangling the user. The user's waist is tightened, making the user feel uncomfortable. When the user's waist circumference becomes smaller, the telescopic device 3 can automatically reduce the distance between the first seat body 21 and the second seat body 22, thereby reducing the length of the belt. Specifically, the telescopic device 3 includes a plug-in mechanism 31 and a telescopic mechanism 32. The plug-in mechanism 31 is arranged between the first seat body 21 and the second seat body 22 to guide the second seat body 22 to perform a telescopic action. The telescopic mechanism 32 is arranged between the plug-in mechanism 31 and the first seat body 21 to push the second seat body 22 back to its original position when the user's waist circumference becomes smaller.

[0021] The plug-in mechanism 31 includes a plug-in protrusion 311 and a plug-in groove 312. The plug-in protrusion 311 is provided on the second base 22, and the plug-in groove 312 is provided on the first base 21. The plug-in protrusion 311 is installed in the plug-in groove 312, and the plug-in protrusion 311 can move in the plug-in groove 312 so as to extend or retract into the plug-in groove 312. The front end of the plug-in protrusion 311 is provided with a guide slope 3111, which is used to guide the plug-in protrusion 311 into the plug-in groove 312.

[0022] The telescopic mechanism 32 includes a moving groove 321, a moving block 322, and a telescopic spring 323. The moving groove 321 is provided on the side wall of the first base 21 and communicates with the plug-in groove 312. The moving block 322 is fixedly connected to the plug-in protrusion 311. The moving block 322 is installed in the moving groove 321. The side wall of the moving groove 321 is provided with a spring fixing groove 3211. One end of the telescopic spring 323 is disposed in the spring fixing groove 3211, and the other end of the telescopic spring 323 is connected to the moving block 322. The telescopic mechanism 32 includes two groups, and the two telescopic mechanisms 32 are symmetrically arranged. Specifically, when the user's waist circumference increases, the plug-in protrusion 311 extends out of the plug-in groove 312, so that the distance between the first seat body 21 and the second seat body 22 increases, thereby increasing the length of the belt. At this time, the moving block 322 will follow the plug-in protrusion 311 to move in the moving groove 321, and the moving block 322 will squeeze the telescopic spring 323; when the user's waist circumference decreases, the moving block 322 will return to its original position under the action of the telescopic spring 323, thereby driving the plug-in protrusion 311 to retract into the plug-in groove 312, so that the distance between the first seat body 21 and the second seat body 22 decreases, thereby reducing the length of the belt.

[0023] A limiting device 4 is provided between the movable block 322 and the first seat 21. The limiting device 4 is used to fix the second seat 22 to the first seat 21 when the belt does not require adaptive adjustment. The limiting device 4 includes a limiting groove 41 and a limiting rod 42. The limiting groove 41 is provided on the first seat 21. The limiting rod 42 is rotatably provided on the movable block 322 and is disposed within the limiting groove 41.

[0024] A rotating device 5 is provided between the first base 21 and the belt buckle body 1, and the first base 21 is rotatably connected to the belt buckle body 1 via the rotating device 5. The rotating device 5 includes a first rotating hole 51, a second rotating hole 52, and a rotating shaft 53. The first rotating hole 51 is provided on the first base 21, the second rotating hole 52 is provided on the belt buckle body 1, and the rotating shaft 53 passes through the first rotating hole 51 and the second rotating hole 52.

[0025] The above are only some specific implementation methods of the present invention, but the design concept of the present invention is not limited to this. Any non-substantial changes to the present invention using this concept shall be deemed as an infringement of the protection scope of the present invention.
