[0038] In order to make the content easier to be clearly understood, the following is further described in detail according to specific embodiments and in combination with the drawings;

[0039] A pull wire buckle solves the technical problem of low structural strength of the connection and easy falling off in the related art, can be manufactured and used, achieves the positive effect of improving the structural strength of the connection and not easy to fall off, and the overall idea is as follows:

[0040] EMBODIMENT

[0041] As shown in Figure 1 , Figure 2 , Figure 3 ; a pull wire buckle comprises:

[0042] The buckle body 10 is connected on the end of the pull wire 100.

[0043] and the buckle seat 20 has a clamping slot 21 for clamping the buckle body 10;

[0044] The clamping slot 21 has a first groove 21-1 and a second groove 21-2;

[0045] One end of the first groove 21-1 is towards the pull wire 100, and the other end is communicated with the second groove 21-2;

[0046] The first groove 21-1 includes a first space 21-11 and a second space 21-12, and the width dimension A of the first space 21-11 is smaller than the width dimension B of the second space 21-12;

[0047] The second groove 21-2 includes a third space 21-21 and a fourth space 21-22, and the width dimension C of the third space 21-21 is smaller than the width dimension D of the fourth space 21-22;

[0048] The width dimension B of the second space 21-12 is greater than the width dimension C of the third space 21-21;

[0049] The first space 21-11, the second space 21-12, the third space 21-21 and the fourth space 21-22 form a concave-convex alternating structure;

[0050] Specifically, in implementation, the buckle body 10 is connected to the end of the pull wire 100, and the buckle body 10 is clamped in the clamping slot 21 of the buckle seat 20. Since the clamping slot 21 has the first groove 21-1 and the second groove 21-2, the first groove 21-1 includes the first space 21-11 and the second space 21-12, the second groove 21-2 includes the third space 21-21 and the fourth space 21-22, the width dimension A of the first space 21-11 is smaller than the width dimension B of the second space 21-12, the width dimension C of the third space 21-21 is smaller than the width dimension D of the fourth space 21-22, and the width dimension B of the second space 21-12 is greater than the width dimension C of the third space 21-21, so that the width direction of the first groove 21-1 and the second groove 21-2 forms a concave-convex alternating structure, the contact area of the buckle body 10 at the clamping slot 21 is increased, and the structural strength of the connection between the buckle body 10 and the buckle seat 20 is relatively good, and the buckle body 10 is not easy to fall off;

[0051] The "concave-convex alternating structure" is explained as follows: due to the different width dimensions of the first space 21-11, the second space 21-12, the third space 21-21 and the fourth space 21-22, the position with small width dimension is "concave", and the position with large width dimension is "convex", as shown in Figure 1 、 Figure 2As shown, the first space 21-11 and the third space 21-21 are "concave", while the second space 21-12 and the fourth space 21-22 are "convex".

[0052] Another implementation method:

[0053] like Figure 1 , Figure 2 , Figure 3 As shown; in practice, the width dimensions A, B, C, and D are the width dimensions of the first groove 21-1 and the second groove 21-2 after the buckle 20 is projected from one side plane;

[0054] The first groove 21-1 has a "T" shaped structure when projected onto a plane; the second groove 21-2 has a "T" shaped structure when projected onto a plane; the shapes of the first groove 21-1 and the second groove 21-2 make the width direction of the first groove 21-1 and the second groove 21-2 form an alternating concave and convex structure, which increases the contact area between the buckle body 10 and the slot 21.

[0055] The width dimension A of the first space 21-11 is equal to the width dimension C of the third space 21-21; the width dimension B of the second space 21-12 is equal to the width dimension D of the fourth space 21-22, forming an alternating concave and convex structure that is more regular, facilitates processing and manufacturing, and is relatively aesthetically pleasing.

[0056] Another implementation method:

[0057] like Figure 1 , Figure 2 , Figure 3 As shown; in implementation, the buckle body 10 includes: a first part 11, a second part 12, a third part 13 and a fourth part 14; after the first part 11, the second part 12, the third part 13 and the fourth part 14 are combined, they match the shape of the card slot 21 and are locked in the card slot 21, making the connection relatively convenient;

[0058] The first part 11 is engaged in the first space 21-11; the second part 12 is engaged in the second space 21-12; the third part 13 is engaged in the third space 21-21; and the fourth part 14 is engaged in the fourth space 21-22. The connection is relatively convenient, and the contact area between the buckle 10 and the slot 21 is increased.

[0059] The length of the first part 11 is greater than the length of the first space 21-11, which increases the contact area between the buckle 10 and the pull wire 100 while the buckle 10 engages with the slot 21. The connection between the buckle 10 and the pull wire 100 is relatively reliable and aesthetically pleasing.

[0060] The first part 11 has a cylindrical shape; the second part 12, the third part 13 and the fourth part 14, when combined, have an "I" shape and are integrally formed with the first part 11; the buckle body 10 has a relatively regular shape, is relatively easy to process and manufacture, and can match the slot 21, increasing the contact area between the buckle body 10 and the slot 21, so that the structural strength of the connection between the buckle body 10 and the buckle seat 20 is relatively good, and it is not easy to fall off or break.

Those skilled in the art can directly and without doubt know how to set it up after seeing the disclosed content, without needing to put in creative effort or conduct excessive experiments.

[0063] The working principle is as follows: The buckle body 10 is connected to the end of the pull wire 100. The buckle body 10 is locked in the slot 21 on the buckle seat 20. Since the slot 21 has a first groove 21-1 and a second groove 21-2, the first groove 21-1 includes a first space 21-11 and a second space 21-12, and the second groove 21-2 includes a third space 21-21 and a fourth space 21-22. The width dimension A of the first space 21-11 is smaller than the width dimension B of the second space 21-12, the width dimension C of the third space 21-21 is smaller than the width dimension D of the fourth space 21-22, and the width dimension B of the second space 21-12 is larger than the width dimension C of the third space 21-21, so that the width direction of the first groove 21-1 and the second groove 21-2 forms an alternating concave-convex structure, which increases the contact area between the buckle body 10 and the slot 21, making the structural strength of the connection between the buckle body 10 and the buckle seat 20 relatively good and not easy to fall off.
