Description

Technical Field

[0001] The utility model relates to the field of belt buckles, and particularly to a belt buckle which is convenient to buckle. Background Art

[0002] Among various existing belts, the most common one is the perforated belt, which is provided with several positioning holes at equal intervals. The corresponding belt buckle has an insertion rod or a hook. When tightening or loosening the belt, the insertion rod or the hook is inserted into or withdrawn from the holes on the belt, so as to adjust the tightness of the belt. However, due to a certain distance between multiple holes on the belt, the minimum adjustment amount of the belt for adjusting the tightness is the distance between one hole. Therefore, it is often difficult to adjust the belt to the most comfortable tightness. Thus, this kind of belt buckle structure generally has difficulty in finely adjusting its tightness.

[0020] The following will clearly and completely describe the technical solutions in the present utility model with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.

[0021] Refer to Figures 1-7 As shown, a belt buckle convenient for buckling includes a belt buckle body 1, a connecting seat 2, a clamping block 3, a positioning device 4, and a pressing device 5. A pair of oppositely arranged rotating convex blocks 11 are provided inside the belt buckle body 1. The connecting seat 2 is rotatably connected to the rotating convex blocks 11. An installation groove 21 is provided at the front end of the connecting seat 2. The clamping block 3 is fixedly arranged in the installation groove 21 for cooperating with the inner side surface of the belt buckle body 1 to tightly press and fix the belt, so that the belt can be fixedly connected to the belt buckle body 1 without punching holes. Therefore, the user can finely adjust the tightness of the belt to make it reach the most comfortable tightness. The positioning device 4 is arranged between the rotating convex blocks 11 and the connecting seat 2. The positioning device 4 is used to relatively fix the connecting seat 2 and the rotating convex blocks 11 to ensure the stability and firmness of the clamping block 3 pressing the belt. The pressing device 5 is arranged on the rotating convex blocks 11 for unlocking the positioning device 4 so that the belt can be separated from the belt buckle body 1.

[0022] The clamping block 3 includes a main body part 31 and an arc-shaped pressing part 32. The main body part 31 is arranged in the installation groove 21, and the arc-shaped pressing part 32 is arranged on the main body part 31. Among them, the main body part 31 and the arc-shaped pressing part 32 are integrally formed. Anti-slip convex lines 321 are provided on the arc-shaped pressing part 32, and the anti-slip convex lines 321 are used to increase the friction between the clamping block 3 and the belt.

[0023] The positioning device 4 includes a positioning cavity 41, a positioning spring 42, a card slot 43, and a positioning column 44. The positioning cavity 41 is arranged on the side wall of the connecting seat 2. The positioning spring 42 is arranged in the positioning cavity 41. The card slot 43 is arranged on the side wall of the rotating convex block 11. The positioning column 44 is arranged in the positioning cavity 41. One end of the positioning column 44 is connected to the positioning spring 42, and the other end of the positioning column 44 is snapped into the card slot 43. Among them, a conical structure 441 is provided at the end of the positioning column 44 snapped into the card slot 43, making it easier for the positioning column 44 to be snapped into the card slot 43.

[0024] The pressing device 5 includes a communication hole 51 and a pressing column 52. The communication hole 51 is provided on the rotating bump 11. The communication hole 51 communicates with the clamping groove 43. The pressing column 52 is arranged in the communication hole 51, and one end of the pressing column 52 extends out of the communication hole 51.

[0025] Specifically, when the belt needs to be detached from the belt buckle body 1, press the pressing column 52, so that one end of the pressing column 52 pushes the positioning column 44 out of the clamping groove 43. At this time, the positioning spring 42 is compressed, and the belt buckle body 1 can rotate relative to the connecting seat 2. Rotate the belt buckle body 1 outwards so that the distance between the inner side surface of the belt buckle body 1 and the arc-shaped pressing part 32 increases, so that the belt can be pulled out of the belt buckle body 1. On the contrary, when the belt needs to be fixed, rotate the belt buckle body 1 inwards so that the distance between the inner side surface of the belt buckle body 1 and the arc-shaped pressing part 32 decreases, so that the clamping block 3 presses and fixes the belt on the inner side surface of the belt buckle body 1. At this time, the clamping groove 43 is opposite to the positioning cavity 41, and the positioning column 44 is pushed out of the positioning cavity 41 under the action of the compressed positioning spring 42 and is clamped into the clamping groove 43.

[0026] A rotating device 6 is provided between the connecting seat 2 and the rotating bump 11. The connecting seat 2 is rotatably connected to the belt buckle body 1 through the rotating device 6. Wherein, the rotating device 6 includes a first rotating hole 61, a second rotating hole 62 and a rotating shaft 63. The first rotating hole 61 is provided on the connecting seat 2, the second rotating hole 62 is provided on the rotating bump 11, and the rotating shaft 63 passes through the first rotating hole 61 and the second rotating hole 62.

[0027] The above are only several specific embodiments of the present invention, but the design concept of the present invention is not limited thereto. Any non-substantive modification made to the present invention using this concept shall fall within the scope of infringement of the protection scope of the present invention.
