Description

Technical Field

[0001] This utility model is a toothed buckle with a built-in reinforcing structure, belonging to the field of buckles. Background Technology

[0002] Buckles are accessories used in daily life to connect, secure, or adjust items, and are commonly found in clothing, backpacks, strollers, and storage products.

[0003] A toothed buckle is a type of fastener that consists of a toothed fastener and a toothed grooved fastener base.

[0004] The fasteners in existing plastic toothed fasteners are one-piece molded structures. Under long-term use or stress, the teeth on the fasteners are prone to breakage, which affects the fastening function. Utility Model Content

[0005] To address the shortcomings of existing technologies, the purpose of this utility model is to provide a toothed buckle with a built-in reinforcing structure, in order to solve the problem that the teeth on the buckle are easily broken under long-term use or stress in existing plastic toothed buckles, which affects the buckling operation.

[0006] To achieve the above objectives, this utility model is implemented through the following technical solution: a toothed buckle with a built-in reinforcing structure, the structure of which includes a buckle member, a connecting ring, and a buckle base. The buckle member has a buckle hole in the middle, and a plurality of buckle teeth are staggered on the inner wall of the buckle hole. Reinforcing plates are provided in the upper and lower interlayers of the buckle member, and reinforcing ribs extend from the reinforcing plates and are embedded in the interlayer of the buckle teeth. The connecting ring is located on one side of the buckle member. The buckle base is fitted into the buckle hole, and the outer wall of the buckle base has a buckle groove that engages with the buckle teeth.

[0007] Furthermore, to prevent scratches and wear on the surface of the item, the ends of several teeth are rounded.

[0008] Furthermore, to facilitate fastening, the fastening teeth are conical structures whose shape and size perfectly match the fastening groove.

[0009] Furthermore, to improve the structural robustness, the fasteners and connecting rings are integrally molded.

[0010] Furthermore, to increase strength, the reinforcing plate is made of plastic, metal, or magnetic material.

[0011] Furthermore, in order to increase the friction of contact and prevent disengagement, the inner wall of the buckle groove is provided with a V-shaped clamping block for elastically clamping and positioning the reinforcing rib.

[0012] The beneficial effects of this utility model are: the toothed buckle with built-in reinforced structure and the buckle itself is designed with reinforcing ribs to strengthen the buckle teeth, which effectively prevents the buckle teeth from breaking easily during long-term use or under stress. Attached Figure Description

[0013] Other features, objects, and advantages of this invention will become more apparent from the following detailed description of non-limiting embodiments with reference to the accompanying drawings: Figure 1 This is a schematic diagram of the toothed buckle with a built-in reinforcing structure according to the present invention; Figure 2 This is a cross-sectional structural diagram of the fastener; Figure 3 This is a schematic diagram of the fastener structure.

[0014] In the diagram: Fastener-1, Connecting Ring-2, Fastener Seat-3, Fastener Hole-11, Fastener Tooth-12, Reinforcing Plate-13, Reinforcing Rib-14, Fastener Groove-31, V-shaped Clamp-32. Detailed Implementation

[0015] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments. Example 1

[0016] Please see Figure 1 , Figure 2 , Figure 3 This utility model provides a toothed buckle technology solution with a built-in reinforcing structure: its structure includes a buckle 1, a connecting ring 2, and a buckle seat 3. The buckle 1 has a buckle hole 11 in the middle, and a plurality of buckle teeth 12 are staggered on the inner wall of the buckle hole 11. Reinforcing plates 13 are provided in the upper and lower interlayers of the buckle 1, and reinforcing ribs 14 extend from the reinforcing plates 13 and are embedded in the interlayer of the buckle teeth 12. The connecting ring 2 is located on one side of the buckle 1. The buckle seat 3 is fitted into the buckle hole 11, and the outer wall of the buckle seat 3 is provided with a buckle groove 31 that engages with the buckle teeth 12.

[0017] The fastener 1 and the buckle seat 3 are both made of nylon. The connecting ring 2 is fixedly connected to the pull rope on the item, which is in a movable state. The buckle seat 3 is directly fixed to the item. As the fastener 1 and the buckle seat 3 are fastened together, the opening or loose part on the item is closed or tightened.

[0018] The shapes of the buckle hole 11 and the buckle base 3 can be customized according to the brand logo, and can be one of the following: round, heart-shaped, oval, or polygonal. However, this utility model is not limited to these and can also be an irregular shape.

[0019] When nylon buckles 1 are used on clothing, they effectively prevent injury caused by the user gripping or pulling them.

[0020] To prevent scratches and wear on the surface of the item, the ends of several teeth 12 are rounded.

[0021] To facilitate fastening, the buckle teeth 12 are tapered structures whose shape and size perfectly match the buckle groove 31.

[0022] To improve the structural robustness, the fastener 1 and the connecting ring 2 are integrally formed.

[0023] To improve strength, the reinforcing plate 13 is made of metal, specifically stainless steel.

[0024] like Figure 3 As shown, in order to increase the friction of contact and prevent disengagement, the inner wall of the buckle groove 31 is provided with a V-shaped clamping block 32 for elastically clamping and positioning the reinforcing rib 14.

[0025] The V-shaped clamp 32 is made of rubber and is connected to the buckle 3 by adhesive bonding.

[0026] The toothed buckle adopts a built-in reinforced structure. The buckle 1 is designed with reinforcing ribs 14 to strengthen the buckle teeth 12, which effectively prevents the buckle teeth 12 from easily breaking during long-term use or under stress. Example 2

[0027] For the sake of brevity, the parts that are the same as those in other embodiments will not be described again. The main description is of the structure that is different from other embodiments of this utility model. The reinforcing plate 13 is made of magnetic material, and the buckle 3 is embedded with metal particles so that when the buckle 3 is fastened into the buckle hole 11, it is attracted to the reinforcing plate 13 and the reinforcing rib 14 through the buckle teeth 12, thereby improving the fastening firmness.

[0028] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. It will be apparent to those skilled in the art that this utility model 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 basic characteristics of this utility model. Therefore, the embodiments should be considered exemplary and non-limiting in all respects. The scope of this utility model is defined by the appended claims rather than the foregoing description, and thus all variations falling within the meaning and scope of equivalents of the claims are intended to be included within this utility model. No reference numerals in the claims should be construed as limiting the scope of the claims.

[0029] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
