Description

Technical Field

[0001] This utility model belongs to the field of connecting buckle technology, specifically relating to an irregular curved surface connecting buckle for Crocs. Background Technology

[0002] In today's era of personalized fashion, Crocs have become a popular daily choice for many people due to their comfort and versatility. The way they are attached to the shoe by inserting buckles into the holes and then attaching favorite accessories to the buckles has become a popular way for people to express their personal style.

[0003] These connecting clips are crucial components linking accessories to Crocs, but in current designs, the end face that connects with the accessory is often a single flat structure. When users want to pair them with accessories with curved surfaces such as cylinders or spheres, the contact between the flat and curved surfaces significantly reduces the effective bonding area. These connecting surfaces can only bond at the tangent point of the curved surface and the flat surface, or at a very small contact area, failing to achieve a full fit. This limited bonding contact directly reduces the strength of the connection between the accessory and the clip. During daily walking and activities, the bonded area is prone to peeling and detachment. Utility Model Content

[0004] The purpose of this invention is to provide a non-circular curved surface connecting buckle for Crocs, aiming to solve the problem that the end face of most accessories is a single planar structure. When users want to pair with accessories with curved surfaces such as cylindrical or spherical surfaces, the contact between the planar and curved surfaces leads to a significant reduction in the effective bonding area. These types of mating surfaces can only bond at the tangent point of the curved surface and the planar surface or at a very small contact area, failing to achieve a full fit. This limited bonding contact directly results in a significant reduction in the connection strength between the accessory and the buckle. During daily walking and activities, the bonded area is prone to peeling and detachment.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an irregular curved surface connecting buckle for Crocs, including a bottom buckle, wherein a truncated cone that passes through the hole in the Croc is glued to the center end of the surface of the bottom buckle, and the top of the truncated cone is connected to the bottom of the top plate. The surface of the top plate has an arc-shaped notch that aligns with the arc-shaped accessory. A through hole is formed at the center end of the arc-shaped notch. A connecting post is fitted inside the through hole. A screw cap is screwed onto the outer wall of the top of the connecting post to fix it in the through hole. The bottom of the connecting post is adhered to the surface of the clip. The bottom of the clip is fastened to the frustum column.

[0006] In order to ensure that the arc-shaped trajectory of the arc-shaped notch is not damaged after the swivel cap and the connecting post are joined, so as to ensure that the subsequent arc-shaped accessories can be completely bonded in the arc-shaped notch, as an irregular curved surface connecting buckle for Crocs of this utility model, preferably, the top ends of the swivel cap and the connecting post are located inside the through hole after they are joined.

[0007] To increase the contact area when the spherical accessory is glued to the truncated column, thereby improving the bonding strength, the irregular curved surface connecting buckle for the clogs of this utility model preferably has an arc opening on the surface of the truncated column that mates with the spherical accessory. The center end of the arc opening has a square groove leading into the truncated column, and the inner wall of the square groove has two slots symmetrically formed.

[0008] In order to make the top plate and the round column easy to assemble and disassemble in actual use, as a non-circular curved surface connecting buckle for the perforated shoe of this utility model, preferably, two inserts are symmetrically glued to the bottom of the buckle, the buckle is inserted into the square groove, and the two inserts at the bottom of the buckle are respectively inserted into a slot. A rectangular opening is provided on the outer wall of the insert near the bottom, and a locking tongue is attached to the edge of the opening below the rectangular opening; The internal dimensions of the rectangular opening are larger than the dimensions of the latch bar, and the latch bar is inserted into the recessed opening on the inner wall of the slot when it is reset.

[0009] Compared with the prior art, the beneficial effects of this utility model are: To use, deform the bottom buckle and pass it through the hole in the Croc. Once the bottom buckle is through, the truncated cone will fit into the hole. When attaching cylindrical accessories, insert the clips through the two inserts at the bottom into the slots, thus installing the top plate into the square slot. Next, fit the through hole on the top plate onto the top of the connecting pillar, and then use the screw cap to secure the connecting pillar and the top plate together. The top plate is now fixed to the top of the truncated cone. At this point, attach cylindrical accessories to the curved recess in the top plate, increasing the bonding area between the cylindrical accessories and the top plate, thereby improving the bond's strength.

[0017] 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.

[0018] Please see Figure 1-6 The present invention provides the following technical solution: an irregular curved surface connecting buckle for Crocs, including a bottom buckle 1, a truncated cone 2 that passes through the hole of the Croc is glued to the center end of the surface of the bottom buckle 1, and the top of the truncated cone 2 is connected to the bottom of the top plate 3. An arc-shaped notch 4 is provided on the surface of the top plate 3 to align with the arc-shaped accessory. A through hole 5 is provided at the center end of the arc-shaped notch 4. A connecting post 7 is fitted inside the through hole 5. A screw cap 6 is screwed onto the outer wall of the top of the connecting post 7 to fix it in the through hole 5. The bottom of the connecting post 7 is adhered to the surface of the clip 8. The bottom of the clip 8 is fastened to the frustum column 2.

[0019] Preferably, the surface of the truncated column 2 is provided with an arc-shaped opening 21 that mates with the circular ornament, and the center end of the arc-shaped opening 21 is provided with a square groove 22 leading into the interior of the truncated column 2, and two slots 23 are symmetrically provided on the inner wall of the square groove 22.

[0020] When the mating surface of the accessory is spherical, there is no need to align the top plate 3 with the frustum 2. The arc 21 on the surface of the frustum 2 is compatible with the corresponding curved surface of the accessory. In this way, the curved surface of the accessory can be bonded to the arc 21 with glue, ensuring that the mating surface is large enough. This makes the connection between the frustum 2 and the accessory more secure after mating.

[0021] Preferably, after the cap 6 and the connecting post 7 are joined, the top ends of both are located inside the through hole 5.

[0022] In practical use, after the top plate 3 is fitted onto the top of the connecting column 7 through the through hole 5, the top of the connecting column 7 does not pass through the horizontal height of the bottom of the through hole 5. Then, the screw cap 6 is screwed onto the threaded structure at the top of the connecting column 7. After screwing it in place, the screw cap 6 will press against the inside of the through hole 5, thus fixing the top plate 3 to the top of the frustum column 2. Preferably, two inserts 81 are symmetrically bonded to the bottom of the card strip 8, the card strip 8 is inserted into the square groove 22, and the two inserts 81 at the bottom of the card strip 8 are respectively inserted into a slot 23; A rectangular opening 82 is provided on the outer wall of the insert 81 near the bottom, and a locking tongue strip 83 is attached to the edge of the opening below the rectangular opening 82. The internal dimensions of the rectangular opening 82 are larger than the dimensions of the latch bar 83. When the latch bar 83 is reset, it is inserted into the recessed opening on the inner wall of the slot 23.

[0023] When the insert 81 is inserted into the slot 23, the rubber locking tongue 83 is compressed into the square groove 22 during the connection. After the insert 81 is fully connected to the slot 23, the locking tongue 83 returns to its original position. The locking tongue 83 then engages with the recessed area on the inner wall of the slot 23, thus creating a relatively stable connection between the insert 81 and the slot 23.

[0024] Working principle: In use, the bottom buckle 1 is squeezed and deformed to pass through the hole in the Croc. After the bottom buckle 1 passes through, the frustum 2 can be locked into the hole in the Croc. When it is necessary to attach cylindrical accessories, the clip 8 is inserted into the slot 23 through the two inserts 81 at the bottom, thereby installing the top plate 3 in the square slot 22. Next, the through hole 5 on the top plate 3 is fitted onto the top of the connecting post 7, and then the connecting post 7 and the top plate 3 are fixed together by the screw cap 6. In this way, the top plate 3 can be fixedly installed on the top of the frustum 2. At this time, cylindrical accessories are glued into the arc-shaped recess 4 of the top plate 3, which increases the bonding area between the cylindrical accessories and the top plate 3, thereby improving the firmness of the bond.

[0025] 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.
