[0020] The following will clearly and completely describe the technical solutions in the embodiments of 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 of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without making creative efforts shall fall within the protection scope of the present utility model.

[0021] Please refer to Figures 1-4, A shoelace-free buckle, comprising a left main body 10 and a right main body 20 that are used in combination. A clamping part 30 is rotatably connected to the lower ends of the left main body 10 and the right main body 20. On one side of the right main body 20, a locking column 201 extends. A notch for sliding assembly is formed in the locking column 201, and a locking hole 2011 is arranged inside the locking column 201. On one side of the left main body 10, a coupling cavity 102 is provided. A locking post 101 adapted to the locking column 201 is formed in the coupling cavity 102. A protrusion 1011 is provided on the locking post 101. The protrusion 1011 is inserted into the locking hole 2011 to form a locking structure. The clamping part 30 includes a rotating shaft 302 inserted into the left main body 10 and the right main body 20 and a connecting plate 301. At one end of the connecting plate 301, clamping teeth 3011 for clamping the shoelace are provided. Tightening straps 40 are arranged on the sides of the left main body 10 and the right main body 20 to tighten the connecting plate 301 after clamping is completed.

[0022] Specifically, the tightening strap 40 is made of an elastic material. When the connecting plate 301 is in a fitting state with the left main body 10 and the right main body 20, the tightening strap 40 tightens the connecting plate 301.

[0023] Specifically, the locking column 201 and the coupling cavity 102 form a covering structure.

[0024] Specifically, the locking column 201 is integrally in a C-shaped structure.

[0025] The shoelace-free buckle of this embodiment mainly includes a left main body 10 and a right main body 20, and the two are designed to be structures that can be paired with each other. The lower ends of the left main body 10 and the right main body 20 are rotatably connected by a rotating shaft 302 to a clamping part 30 for clamping and fixing the shoelace. On one side of the right main body 20, a locking column 201 extends outward. A notch is formed in the locking column 201 along its length direction, facilitating the insertion of a finger or other tool for sliding operation. A locking hole 2011 is arranged inside the locking column 201 for cooperating with the corresponding structure on the left main body 10 to achieve locking.

[0026] On the corresponding side of the left main body 10, a coupling cavity 102 is provided. Its shape matches that of the locking column 201 so that the locking column 201 can be smoothly inserted therein. Inside the coupling cavity 102, a locking post 101 is formed. A protrusion 1011 is designed on the locking post 101. After the locking column 201 is completely inserted into the coupling cavity 102, the protrusion 1011 can accurately be inserted into the locking hole 2011 to form a stable locking structure, ensuring the tight combination of the left main body 10 and the right main body 20 and not being easily separated.

[0027] The specific structure of the occluding part 30 includes a rotating shaft 302 and a connecting plate 301. The rotating shaft 302 is respectively inserted into the preset rotating holes 202 of the left main body 10 and the right main body 20, enabling the connecting plate 301 to rotate within a certain range. One end of the connecting plate 301 is provided with occluding teeth 3011. These occluding teeth 3011 are designed to be sharp enough and arranged closely to ensure that they can effectively bite the shoelace and prevent it from sliding.

[0028] In addition, each side of the left main body 10 and the right main body 20 is also equipped with a fastening strap 40. These fastening straps 40 are made of elastic materials. When the connecting plate 301 bites the shoelace through the occluding teeth 3011 and rotates to a position where it fits with the left main body 10 and the right main body 20, the fastening strap 40 can tightly wrap the connecting plate 301 by its elasticity, further strengthening the fixing effect of the shoelace.

[0029] The locking post 201 is designed to have an overall C-shaped structure. This design not only enhances the structural strength of the locking post 201 but also forms a more tightly wrapped structure between the locking post 201 and the engaging cavity 102. When the locking post 201 is inserted into the engaging cavity 102, the C-shaped form can more effectively prevent the locking post 201 from accidentally slipping out, further improving the safety and stability of the lace-free shoe buckle.

[0030] When in use, the user first passes the shoelace through an appropriate position of the occluding part 30, and then manually operates to make the occluding part 30 rotate around the rotating shaft 302 until the occluding teeth 3011 tightly bite the shoelace. Then, align the locking post 201 on the right main body 20 with the engaging cavity 102 of the left main body 10 and insert it until the protruding part 1011 completely enters the locking hole 2011 to achieve locking. Finally, utilize the elastic property of the fastening strap 40 to firmly fix the connecting plate 301 between the left main body 10 and the right main body 20 to complete the fixing of the shoelace.

[0031] For those skilled in the art, it is obvious that the present utility model is not limited to the details of the above exemplary embodiments, and can be implemented in other specific forms without departing from the spirit or basic characteristics of the present utility model. Therefore, from any perspective, the embodiments should be regarded as exemplary and non-limiting.
