Description

Technical Field

[0001] This utility model relates to the field of clothing accessories, and in particular to an overlapping frame type waist buckle structure. Background Technology

[0002] Waist buckles are widely used in clothing, outdoor equipment, industrial protective products and other fields, and their performance directly affects the user experience and safety of the product.

[0003] Existing conventional split buckles mostly adopt a structure of "one buckle hollowed out for support, and the other buckle embedded for adaptation." That is, one buckle supports the other buckle through a thin support point in the hollowed-out area, and the size of the embedded buckle must be smaller than that of the support buckle. This structure has obvious defects: the thickness of the support point is limited, making it prone to breakage under long-term use or load, resulting in insufficient structural strength; the size of the buckles is limited by the adaptation relationship, resulting in poor flexibility of use.

[0004] Therefore, it is necessary to provide an overlapping frame type waist buckle structure to solve the above technical problems. Utility Model Content

[0005] This utility model provides an overlapping frame type waist buckle structure to solve the problems of thin and easily broken waist buckle load-bearing points and insufficient design flexibility due to the limitation of buckle size by the adaptation relationship in the prior art.

[0006] To solve the above-mentioned technical problems, the technical solution of this utility model is: an overlapping frame type waist buckle structure, which includes: The first latch has a first webbing hole at one end and a first connecting ring at the other end. The first latch also includes a locking support and a locking alignment point connected to the first connecting ring. The second latch has a second webbing hole at one end and a second connecting ring at the other end. The second latch also has a locking port adapted to the locking support and a locking alignment hole adapted to the locking alignment point. When the first latch and the second latch are engaged, the engaging support post is inserted into the engaging port, the engaging alignment point is fitted into the engaging alignment hole, and the first connecting ring and the second connecting ring are spliced ​​together to form a ring support structure.

[0007] In this invention, the engaging support and the engaging mating point are arranged opposite each other along the circumference of the first connecting ring; The engaging opening and the engaging alignment hole are distributed circumferentially along the second connecting ring.

[0008] In this invention, when the first latch and the second latch are engaged, the center surfaces of the first latch and the second latch overlap.

[0009] In this invention, both the first buckle and the second buckle are bent surface structures, which are adapted to the curve of the human waist.

[0010] In this invention, the first connecting ring is a circular frame structure; the structure of the second connecting ring matches that of the first connecting ring.

[0011] In this invention, the first connecting ring is a polygonal frame structure; the structure of the second connecting ring matches that of the first connecting ring.

[0012] In this invention, a decorative layer is provided on the side of the first latch away from the engaging support post, and the decorative layer is used to distinguish the front and back of the first latch.

[0013] In this utility model, the first latch includes: The first connecting ring is located at one end of the first latch; and The first webbing loop is located below the first connecting ring, and the first webbing hole is provided on the first webbing loop; Wherein, one end of the first webbing loop is connected to the first connecting ring through the locking post, and the first webbing loop, the locking post and the first connecting ring form a groove for the second connecting ring to be inserted and positioned.

[0014] In this utility model, the second buckle further includes the second webbing loop buckle, the second webbing hole is provided on the second webbing loop buckle, and the second webbing hole communicates with the inner hole of the second connecting ring so that the first connecting ring can pass through.

[0015] In this utility model, both the first latch and the second latch are integrally formed structures.

[0016] Compared with the prior art, the advantages of this utility model are as follows: The overlapping frame waist buckle structure of this utility model forms a double precise locking mechanism through the insertion of the locking support and the locking port, and the fitting of the locking alignment point and the locking alignment hole. Combined with the complete ring support structure spliced ​​after the first connecting ring and the second connecting ring are fastened, it replaces the local thin load-bearing point of the traditional waist buckle. It can evenly distribute the load to the entire ring area, greatly enhance the structural rigidity and deformation resistance, effectively solve the problems of thin and easily broken load-bearing points and easy loosening of the fastening of the traditional waist buckle, and ensure the safety of use.

[0017] Meanwhile, this structure abandons the traditional design logic of "the embedded side lock must be smaller than the load-bearing side lock" in double-opening waist buckles. The first and second locks do not need to be limited in size, and the shape and functional layout can be freely planned according to needs, which greatly improves design flexibility and solves the problem of lock size being limited by the adaptation relationship in the existing technology. Moreover, the dual positioning structure makes the buckle alignment more precise. The first and second webbing holes can stably adapt to various specifications of webbing, making installation and use convenient. It is suitable for diverse scenarios such as clothing, outdoor equipment, and industrial protective equipment. Attached Figure Description

[0027] 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0028] In the diagram, units with similar structures are represented by the same labels.

[0029] The terms "first" and "second" in this utility model are used for descriptive purposes only and should not be construed as indicating or implying relative importance, nor as a restriction on the order of events.

[0030] Please refer to Figure 1 , Figure 2 and Figure 3 ,in Figure 1 This is a schematic diagram of the overall structure of the overlapping frame waist buckle structure of a preferred embodiment of the present utility model; Figure 2 A perspective view of the back of the overlapping frame type waist buckle structure, which is a preferred embodiment of this utility model; Figure 3 An analysis of the overlapping frame type waist buckle structure of the preferred embodiment of this utility model. Figure 1 .

[0031] The following is a preferred embodiment of an overlapping frame type waist buckle structure provided by this utility model, which can solve the above technical problems.

[0032] A preferred embodiment of the overlapping frame waist buckle structure provided by this utility model is as follows: An overlapping frame waist buckle structure includes a first buckle 11 and a second buckle 12; one end of the first buckle 11 is provided with a first webbing hole 112, and the other end of the first buckle 11 is provided with a first connecting ring 113. The first buckle 11 also includes a locking support post 114 and a locking alignment point 115 connected to the first connecting ring 113; one end of the second buckle 12 is provided with a second webbing hole 122, and the other end of the second buckle 12 is provided with a second connecting ring 123. The second buckle 12 also has a locking opening 124 adapted to the locking support post 114 and a locking alignment hole 125 adapted to the locking alignment point 115.

[0033] When the first latch 11 and the second latch 12 are engaged, the locking support 114 is inserted into the locking opening 124, the locking alignment point 115 is engaged with the locking alignment hole 125, and the first connecting ring 113 and the second connecting ring 123 are spliced ​​together to form a ring support structure.

[0034] In this embodiment, the overlapping frame waist buckle structure achieves precise alignment of the first buckle 11 and the second buckle 12 through a dual positioning structure of "engaging support column 114 and engaging alignment point 115", making it less prone to loosening or slipping after fastening; the webbing hole can stably connect the clothing cord or belt body, ensuring a firm connection between the waist buckle and the carrier; the ring support structure formed by splicing the first connecting ring 113 and the second connecting ring 123 greatly improves the overall structural strength of the waist buckle, avoids deformation due to stress after fastening, and extends its service life.

[0035] The overlapping border type waist buckle structure in this embodiment is described in detail below: Combination Figure 1 and Figure 2 In this embodiment, when the overlapping frame waist buckle structure is engaged, the center surface of the first buckle 11 overlaps with the center surface of the second buckle 12. This ensures that the waist buckle is evenly stressed after engagement, preventing tilting or loosening caused by unilateral stress. The overlap of the center surfaces of the first buckle 11 and the second buckle 12 ensures coaxiality of the first buckle 11 and the second buckle 12 after engagement, further enhancing structural stability and improving the visual harmony of the product.

[0036] Both the first buckle 11 and the second buckle 12 are curved surface structures adapted to the curve of the human waist. The curved surface structure has a high degree of conformity to the curve of the human waist, reducing gaps when wearing.

[0037] Combination Figure 3 and Figure 4 In this invention, the engaging support 114 and engaging alignment point 115 of the first latch 11 are arranged opposite each other circumferentially along the first connecting ring 113, and the engaging opening 124 and engaging alignment hole 125 of the second latch 12 are correspondingly distributed circumferentially along the second connecting ring 123. This relatively distributed engaging structure ensures that the engaging force is evenly applied to the entire connecting ring, avoiding damage to parts caused by concentrated local forces; the force is applied more smoothly during engagement, eliminating the need for deliberate alignment and improving operational convenience. In this embodiment, the first connecting ring 113 is specifically configured as a circular frame structure, with its circumferential contour being a continuous and smooth closed curve without obvious protrusions at the edges and corners. The shape and size of the second connecting ring 123 are completely adapted to the first connecting ring 113, that is, the second connecting ring 123 is also a circular frame structure, and its inner diameter and outer diameter are consistent with the inner diameter and outer diameter of the first connecting ring 113.

[0038] The first connecting ring 113 and the second connecting ring 123 of the circular frame structure transmit force circumferentially without dead angles. The resulting circular support structure has stronger integrity and can further disperse the tension and pressure during the use of the waist buckle, avoiding local stress concentration. At the same time, the smooth contour of the circular frame is suitable for casual wear, everyday clothing, and other scenarios. Its simple and smooth appearance meets the aesthetic needs of the general public and enhances the product's adaptability in daily outfits.

[0039] Furthermore, the first connecting ring 113 in this application can also be configured as a polygonal frame structure, with its circumference formed by several straight sides connected sequentially to form a closed frame (preferably a rectangular frame structure in this embodiment, but it can also be configured as a regular hexagon, regular octagon, or other polygonal structure according to actual needs). The structure of the second connecting ring 123 is completely matched with that of the first connecting ring 113, that is, the second connecting ring 123 corresponds to a polygonal frame structure with the same number of sides and the same size, ensuring that the two can be accurately spliced ​​when they are fastened together.

[0040] The polygonal frame structure of the connecting rings has a clear outline and regular edges and corners, making it suitable for workwear, outdoor clothing, and other scenarios that require a strong structural feel, thus meeting the needs of diverse clothing styles. Furthermore, when the first and second connecting rings (123) of the same structure are spliced ​​together, the corners of the ring support structure are highly aligned, and the force transmission path is clear, avoiding support failure due to structural misalignment and ensuring the structural strength and stability of the waist buckle under high-intensity usage scenarios.

[0041] In this embodiment, the first latch 11 includes a first webbing loop 111, a locking post 114, and a first connecting ring 113. The first webbing loop 111 is located below the first connecting ring 113, and forms a first webbing hole 112. One end of the first webbing loop 111 is connected to the first connecting ring 113 through the locking post 114. The first webbing loop 111, the locking post 114, and the first connecting ring 113 form a groove for the second connecting ring 123 to be inserted and positioned. The integrated structure reduces the number of parts, lowers assembly complexity and production costs; the webbing loop directly forms the webbing hole, resulting in a compact structure and reliable connection, avoiding cracking at the hole.

[0042] Combination Figure 5 As shown, the height of the locking post 114 is the same as the thickness of the first buckle 11, ensuring that the first and second buckles 12 fit tightly after being fastened without gaps or wobbling, thus improving wearing comfort and structural stability.

[0043] In this embodiment, the second buckle 12 includes a second webbing loop 121 and a second connecting ring 123; the second webbing loop 121 forms a second webbing hole 122, and the second connecting ring 123 is connected to one end of the second webbing loop 121. The structure is simple and compact, facilitating manufacturing; the direct connection between the webbing loop and the connecting ring reduces stress concentration and improves the structural strength of the second buckle 12; the webbing hole is stably formed and can be adapted to webbing or belts of different widths, ensuring a secure connection that is not easily detached.

[0044] like Figure 6As shown, the second webbing hole 122 is provided on the second webbing loop 121, and the second webbing hole 122 communicates with the inner hole of the second connecting ring 123 for the first connecting ring 113 to pass through. The second webbing loop 121 and the second connecting ring 123 are integrally connected, and their interiors form a continuous hollow structure, that is, the inner cavity of the second webbing loop 121 and the inner cavity of the second connecting ring 123 are interconnected without any additional obstruction or partition structure. This interconnected design can effectively expand the assembly space of the first latch 11 and the second latch 12. The interconnected structure makes the internal space of the second latch 12 more efficient, provides more room for movement of hands or tools during assembly, reduces the difficulty of precise docking of the locking components, improves assembly efficiency, and does not affect the overall structural strength and support stability of the second latch 12.

[0045] The following is a second embodiment of the overlapping frame type waist buckle structure of this utility model: Combination Figure 7 In this embodiment, the first latch 11 is located away from the engaging support 114 ( Figure 7 A decorative layer 216 is provided on one side (not shown in the image). The decorative layer 216 is used to distinguish the front and back of the first latch 11. The decorative layer 216 can intuitively distinguish the front and back, allowing users to quickly install the product without repeated confirmation, thus improving assembly efficiency. The decorative layer 216 replaces the traditional markings, which not only distinguishes functions but also beautifies the product appearance, enhancing product recognition and design.

[0046] In this embodiment, the decorative layer 216 of the first latch 11 can be a raised or recessed mark (a graphic mark or a text mark, etc.). Raised or recessed marks have a three-dimensional effect, are more wear-resistant and less prone to fading than flat printing, and extend the service life of the mark; the mark can be used as a brand mark or product model to distinguish, enhancing brand recognition and product personalization; the raised and recessed structure facilitates identification during blind operation, further improving ease of use.

[0047] The working principle of this utility model: 1. Pass the clothing cord or belt body through the first webbing hole 112 of the first buckle 11 (integratedly formed by the first webbing loop 111) and the second webbing hole 122 of the second buckle 12 (integratedly formed by the second webbing loop 121).

[0048] 2. When fastening, the engaging support 114 and engaging alignment point 115 on the first latch 11 are arranged circumferentially opposite to each other along the first connecting ring 113, and are aligned with the engaging opening 124 and engaging alignment hole 125 on the second latch 12. The fast alignment is achieved through dual positioning of "insertion and fitting".

[0049] 3. The cross-sectional shape of the locking support 114 and the locking opening 124 is precisely matched (circular, square or polygonal can be selected) to avoid relative rotation after locking; at the same time, the first connecting ring 113 and the second connecting ring 123 are spliced ​​to form a complete ring support structure, which, together with the overlapping center surface after locking, ensures the coaxiality and uniform force of the two, and prevents unilateral tilting or loosening.

[0050] 4. Both the first buckle 11 and the second buckle 12 adopt a curved surface structure adapted to the curve of the human waist. When worn, the curved surface fits closely to the waist contour, reducing gaps and distributing contact pressure, preventing the buckle from shifting during exercise or daily activities, and reducing marks and discomfort caused by prolonged wear. The decorative layer 216 on the side of the first buckle 11 away from the locking support 114 can be used to visually distinguish the front and back. With the raised / recessed markings on the decorative layer 216, assembly can be quick and easy without repeated confirmation, improving ease of use.

[0051] 5. The ring-shaped support structure significantly improves the overall strength of the buckle, preventing deformation under stress; the height of the locking post 114 is consistent with the thickness of the first latch 11, ensuring that the first and second latches 12 fit tightly without gaps or shaking after fastening. During disassembly, applying force in opposite directions to both sides will disengage the locking post 114 from the locking opening 124 and the locking alignment point 115 from the locking alignment hole 125, ensuring smooth operation without damaging the components and enabling repeated and stable use.

[0052] This completes the usage process of the overlapping frame type waist buckle structure of this preferred embodiment.

[0053] In summary, although the present invention has been disclosed above with reference to preferred embodiments, the above preferred embodiments are not intended to limit the present invention. Those skilled in the art can make various modifications and refinements without departing from the spirit and scope of the present invention. Therefore, the scope of protection of the present invention shall be determined by the scope defined in the claims.
