[0021] In order to make the purpose, technical solution and advantages of the utility model clearer, the technical solution of the utility model will be further described below.

[0022] This embodiment provides a fastening buckle, such as Figure 1 and Figure 2As shown, it includes a sub-button 2 and a mother button 1, wherein the sub-button 2 includes an end cover 23, a guide head 21 and a guide column 22, one end of the guide column 22 is connected to the end cover 23, and the other end is connected to the conical guide head 21, the head end diameter of the conical guide head 21 is smaller than the bottom end diameter, and four limiting grooves are provided between the bottom end of the guide head 21 and the guide column 22; in order to cooperate with the structure of the sub-button 2, as shown in FIG. Figure 3 As shown, the female buckle 1 includes a pressure cover 14 and four elastic feet 11. A through hole is provided in the middle of the pressure cover 14 for plugging in the sub-buckle 2. The four elastic feet 11 are arranged at equal intervals around the through hole and form a circle. The inner diameter of the elastic foot circle formed is larger than the diameter of the head end of the conical guide head 21. In addition, a limiting boss 12 is provided at the bottom of each elastic foot 11. The limiting boss 12 corresponds to the limiting groove on the sub-buckle 2 and is fixed by mutual clamping; the inner diameter of the boss circle surrounded by the limiting boss 12 is smaller than the diameter of the guide column 22 and also smaller than the bottom diameter of the conical guide head 21, so that the limiting boss 12 falls into the limiting groove, and the above-mentioned diameter difference is used to achieve rapid positioning and limiting clamping fixation.

[0023] In this embodiment, a fitting groove is also provided in the middle of the surface of the female buckle 1, which is used to fit the end cover 23 of the sub-buckle 2. The sub-buckle 2 is passed through the middle through hole of the female buckle pressing cover 14, and the sub-buckle end cover 23 is continuously pressed. The limiting boss 12 on the elastic foot 11 falls into the limiting groove on the sub-buckle 2, so as to achieve rapid positioning and clamping fixation. At the same time, the end cover 23 of the sub-buckle 2 is fitted into the fitting groove. The surface and back of the female buckle 1 are both designed with glue removal, which saves the production materials of the product.

[0024] In this embodiment, since the outer diameter of the gland 14 is larger than the outer diameter of the circle formed by the four elastic feet 11, the gland 14 has an additional skirt relative to the circle formed by the elastic feet 11. Figure 4 As shown, holes are opened on the body sheet metal 4 and the guard plate 3, and the fastening buckle of this embodiment is passed through the holes. Through the snap-fitting of the sub buckle 2 and the female buckle 1, the guard plate 3 and the body sheet metal 4 are fixed between the skirt of the gland 14 and the elastic foot 11 of the female buckle 1, so as to achieve a tight and firm connection. In order to facilitate quick disassembly, as shown in FIG. Figure 1 As shown, a gap groove 13 is also provided at the outer diameter edge of the pressure cover of the mother buckle 1, and the sub-buckle 2 is pried through the gap groove 13, so that the limiting groove of the sub-buckle 2 is disengaged from the limiting boss 12 on the mother buckle spring foot 11, so that the buckle can be easily pulled out from the perforation of the guard plate 3 and the sheet metal 4, thereby realizing the quick release of the guard plate 3 and the sheet metal 4.

[0025] The above are only preferred embodiments of the present invention and do not limit the present invention in any way. Any technician in the relevant technical field, without departing from the scope of the technical solution of the present invention, may make any equivalent replacement or modification to the technical solution and technical content disclosed in the present invention, which shall be deemed as the content of the technical solution of the present invention and still fall within the protection scope of the present invention.
