[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] like Figure 1-5As shown, a magnetic snap fastener includes a sub-buckle structure, comprising a sub-buckle 1, wherein the sub-buckle 1 is provided with a female buckle 2 that is attracted and fastened to it. The sub-buckle 1 includes a base 3 located at the bottom and a connecting block 4 protruding on the base 3. The base 3 is used to install on items such as backpacks, shoulder straps, and child seats, and is fastened to the female buckle 2 through the connecting block 4. The connecting block 4 is provided with a connecting part 5 that engages with the female buckle 2 and restricts the movement of the female buckle 2.

[0025] The connecting part 5 includes a mounting hole 6 at the center of the connecting block 4 and a limiting step 7 distributed in a ring on the inner wall of the mounting hole 6.

[0026] The bottom of the female buckle 2 is provided with a male buckle mounting groove 8, and the center of the male buckle mounting groove 8 is provided with a protruding mounting cavity 9. The male buckle mounting groove 8 is adapted to the outer contour of the connecting block 4, and the mounting cavity 9 is adapted to the inner contour of the mounting hole 6. When fastened, the connecting block 4 is installed in the male buckle mounting groove 8, which is the first lateral limit. At the same time, the mounting cavity 9 is also embedded in the mounting hole 6, which is the second lateral limit. This greatly increases the stability of the female buckle 2 and the male buckle 1 after fastening. After fastening, the female buckle 2 is not easy to shake, ensuring the excellent quality of the product and providing users with a good user experience.

[0027] The mounting cavity 9 is equipped with a movable locking member 10. The locking member 10 is moved by the buttons on both sides of the female buckle 2. The locking member 10 partially protrudes from the mounting cavity 9 and abuts against the limiting step 7, which is used to longitudinally lock the female buckle 1 and the female buckle 2. When unlocking, the locking member 10 moves into the mounting cavity 9 and disengages from the lower end of the limiting step 7, so that the female buckle 2 can be pulled up and removed.

[0028] The bottom of the female buckle 1 is provided with an annular groove 11, and an annular magnetic element 12 is installed in the annular groove 11. The female buckle 2 is also equipped with a magnet or metal element corresponding to the magnetic element 12. This can guide the mounting cavity 9 into the mounting hole 6. The adsorption after fastening can further increase the connection strength and make it less likely to fall off.

[0029] The bottom of the sub-button 1 is provided with a base plate 13, which covers the bottom of the annular groove 11 and the mounting hole 6. After the magnetic suction member 12 is inserted into the annular groove 11, the base plate 13 is installed by snapping. After the base plate 13 and the sub-button 1 are assembled, the bottom surfaces of the base plate 13 and the sub-button 1 are in the same horizontal direction. When the sub-button 1 is sewn onto backpacks, shoulder straps, or other items, the base plate 13 presses down on the fabric to prevent the fabric from protruding into the mounting hole 6 and thus avoiding affecting the fastening of the mounting cavity 9.

[0030] The upper end of the mounting hole 6 is provided with a guide part 14, which is an inclined surface. The guide part 14 can play a guiding role during the insertion of the mounting cavity 9, which helps with assembly.

[0031] The connecting block 4 includes an annular connecting block, and the mounting cavity 9 includes a cylindrical mounting cavity, which can be snapped into the sub-snap mounting slot 8 from all 360 degrees. No calibration is required when snapping it in, making it convenient for users to snap in.

[0032] The outer wall of the connecting block 4 is inclined, and the contact area between the outer wall of the connecting block 4 and the inner wall of the buckle mounting groove 8 further increases the stability after fastening and makes it less prone to shaking.

[0033] The base 3 has an annular groove 15 on its outer edge for sewing onto items such as backpacks, baby carriers, and child seats.

[0034] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within this invention, and no reference numerals in the claims should be construed as limiting the scope of the claims.
