Description

Technical Field

[0001] This utility model belongs to the field of clog accessories technology, specifically relating to a buckle with a U-shaped locking structure. Background Technology

[0002] Crocs are shoes with a wide upper and perforated surfaces. They are usually made of lightweight, soft, and breathable materials such as rubber or EVA, and their design emphasizes comfort and functionality.

[0003] The disc buckles used on Crocs are a core component for DIY decoration. They are typically made of plastic or metal and designed with a small round buckle at the bottom. They are installed by snapping the buckle in half at a 45-degree angle and then pressing it flat to secure it. However, this method of forcibly inserting the buckle into the holes on the surface of the Croc causes the material around the holes to gradually deform due to continuous external pressure and friction. This causes the originally regular holes to slowly enlarge. As the holes grow larger, the gap between the buckle and the holes also increases, leading to the buckle wobbling during daily use and even the buckle falling off. Utility Model Content

[0004] The purpose of this utility model is to provide a buckle with a U-shaped locking structure, which aims to solve the problem that the installation method of directly forcibly fastening the bottom of the buckle into the hole on the surface of the clog causes the originally regular hole to gradually enlarge. As the hole continues to grow larger, the gap between the buckle and the hole will also increase, which will lead to the buckle shaking during daily use, or even the buckle falling off.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a buckle with a U-shaped locking structure, including a bottom buckle, a disc base connected to the center of the bottom buckle via a docking component, and a petal ornament connected to the center of the disc base via a disassembly component; The docking assembly includes a docking part disposed between the bottom buckle and the disc seat for docking, a positioning part connected to the inner wall of the docking part for docking and fixing, and an upper positioning plate connected to the outer surface of the upper docking part.

[0021] 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.

[0022] Please see Figure 1-6 The present invention provides the following technical solution: a buckle with a U-shaped locking structure, including a bottom buckle 1, a disc base 2 connected to the center of the bottom buckle 1 through a docking component 4, and a petal ornament 3 connected to the center of the disc base 2 through a disassembly component 5. The docking assembly 4 includes a docking part 41 disposed between the bottom buckle 1 and the disc seat 2 for docking, a positioning part 42 connected to the inner wall of the docking part 41 for docking and fixing, and an upper positioning plate 43 connected to the outer surface of the upper docking part 41.

[0023] Preferably, the bottom buckle 1 includes a lower limiting plate 11 connected to the bottom of the docking part 41, and a silicone pad 12 fitted on the bottom side and side surface of the lower limiting plate 11. In practical use, the lower limit plate 11 is wrapped by the silicone pad 12, which can prevent the lower limit plate 11 from directly contacting the user's instep and thus avoid causing scratches to the instep.

[0024] Preferably, the docking part 41 includes a U-shaped column 411 connected to the center of the lower limit plate 11, and a docking cylinder 412 sleeved on the surface of the column 411 and connected to the bottom of the disc seat 2. In actual use, during assembly, the bottom buckle 1 drives the column 411 through the hole of the clog, and then the disc seat 2 drives the docking cylinder 412 to fit onto the surface of the column 411, thus facilitating the docking between the bottom buckle 1 and the disc seat 2.

[0025] Preferably, the positioning part 42 includes a first inclined surface 421 at the end of the column 411, a slot 422 in the middle of the column 411, and a block 423 connected to the inner wall of the docking cylinder 412. The locking block 423 includes a retaining ring 4231 connected to the inner wall of the docking cylinder 412, and a second inclined surface 4232 disposed on the bottom side of the retaining ring 4231; In practical use, when the docking cylinder 412 moves to the surface of the first inclined surface 421 and moves downward, the docking cylinder 412, through the retaining ring 4231 and the second inclined surface 4232, presses the first inclined surface 421, causing the two vertical parts of the column 411 to bend inward. When the docking cylinder 412 drives the retaining ring 4231 to move to the outside of the slot 422, the two vertical parts of the column 411 recover their deformation through their own elasticity. Thus, the position of the docking cylinder 412 can be fixed by the engagement of the retaining ring 4231 and the slot 422, thereby realizing the docking between the docking cylinder 412 and the column 411.

[0026] Preferably, the disassembly and assembly component 5 includes a fixing hole 51 formed on the surface of the base of the petal ornament 3, and a fixing part 52 connected to the top of the disc base 2 and engaged with the fixing hole 51; The fixing part 52 includes a first fixing rod 521 and a second fixing rod 522 connected directly above the disc base 2, and a spring piece 523 disposed between the first fixing rod 521 and the second fixing rod 522. The spring piece 523 is fitted between the first rod part 5211 and the second rod part 5221. In practical use, the spring piece 523 can be used to keep the first fixing rod 521 and the second fixing rod 522 in an open state.

[0027] Preferably, the first fixing rod 521 includes a first rod portion 5211 connected to the top of the disc seat 2, a first spherical protrusion 5212 connected to the end of the first rod portion 5211, and a third inclined surface 5213 provided on the inner sidewall of the first rod portion 5211. The second fixing rod 522 includes a second rod portion 5221 connected to the top of the disc seat 2, a second spherical protrusion 5222 connected to the end of the second rod portion 5221, and a fourth inclined surface 5223 provided on the inner side wall of the second rod portion 5221. In practical use, after the first fixing rod 521 and the second fixing rod 522 pass through the interior of the fixing hole 51, the first fixing rod 521 and the second fixing rod 522 are in an open state by means of the spring piece 523 when no force is applied, so that the position of the petal ornament 3 can be fixed by means of the first spherical protrusion 5212 and the second spherical protrusion 5222.

[0028] The working principle of this utility model in specific use is as follows: When installing the disc buckle, firstly, the bottom buckle 1 drives the column 411 through the hole of the clog. Then, the disc seat 2 drives the connecting cylinder 412 to fit onto the surface of the column 411. The connecting cylinder 412 drives the second inclined surface 4232 to move to the first inclined surface 421, which presses the two vertical parts of the column 411 and causes them to bend and deform. When the connecting cylinder 412 drives the retaining ring 4231 to move to the outside of the slot 422, the two vertical parts of the column 411 recover their deformation. Thus, the position of the connecting cylinder 412 is fixed by the engagement of the retaining ring 4231 and the slot 422, thereby realizing the installation of the disc buckle. When the first spherical protrusion 5212 and the second spherical protrusion 5222 are subjected to a squeezing force in the direction of mutual approach, they can cause the first fixing rod 521 and the second fixing rod 522 to bend in the direction of mutual approach. At this time, the compressed spring piece 523 can be bent and deformed. Through the setting of the third inclined surface 5213 and the fourth inclined surface 5223, when the inner walls of the first fixing rod 521 and the second fixing rod 522 are closed, the petal ornament 3 can be pulled upward and removed. Then, the petal ornaments 3 of different flower shapes fit the fixing hole 51 onto the surface of the first spherical protrusion 5212 and the second spherical protrusion 5222 and move towards the surface of the first spherical protrusion 5212 and the second spherical protrusion 5222. When pressed down, the first spherical protrusion 5212 and the second spherical protrusion 5222 are subjected to pressure, which can drive the first fixing rod 521 and the second fixing rod 522 to come together and compress the spring piece 523. When the fixing hole 51 is fitted onto the surface of the first fixing rod 521 and the second fixing rod 522, the spring piece 523 uses its own elasticity to squeeze the first fixing rod 521 and the second fixing rod 522 to reset, thereby fixing the position of the disc seat 2 through the first spherical protrusion 5212 and the second spherical protrusion 5222. This allows the petal ornament 3 to be replaced, thereby enhancing the novelty of the disc buckle.

[0029] It should be noted that the flower shape of the petal ornament 3 in this application is not limited to the shape shown in the accompanying drawings, and each petal ornament 3 has a fixing hole 51.

[0030] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
