Technical Field

[0001] This utility model relates to the field of buckle technology, and more specifically, to a buckle. Background Technology

[0002] With the increasing demand for pets in society, pet cages can serve as both pet homes and transportation tools. Traditional welded cages consist of a cage body and an openable door. The cage body is mostly non-disassembly and inconvenient to carry. Existing assemblable pet cages are often prone to loosening due to poor connections and impacts from pet activities, resulting in poor stability. Currently, most iron pipe cages on the market are installed and fixed with screws or hinges and screws.

[0003] For example, utility model patent publication number CN212877112U discloses a fixed square tube pet cage with buckles, including two front square tube frames and two rear square tube frames. Several first buckles are installed between the two front square tube frames and between the two rear square tube frames. Several second buckles are installed between the two side square tube frames. Several third buckles are installed between the side square tube frames and adjacent front and rear square tube frames. The first, second, and third buckles of this patent are all installed using screws. Each buckle has many components and corresponds to different connection points, which can easily lead to confusion. Each assembly and disassembly requires tightening or loosening screws with a screwdriver, making the assembly process complex, time-consuming, and labor-intensive. Therefore, an assemblable pet cage should use reliable buckles for fixing to ensure that all components of the cage are tightly connected and highly stable. Utility Model Content

[0023] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0024] Please refer to Figure 1 The present invention provides a buckle, including a first buckle body 10 and a second buckle body 20. The components of the present invention will be described in detail below with reference to the accompanying drawings.

[0025] like Figures 1 to 2 As shown, the first buckle 10 and the second buckle 20 have the same structure. The first buckle 10 and the second buckle 20 can be arranged in a mirror image symmetrically and can be interlocked when they are directly opposite each other. In this embodiment, the first buckle 10 and the second buckle 20 with the same structure can achieve bidirectional self-locking. Only one part needs to be molded, which greatly reduces the production cost. Users do not need to distinguish between left and right parts. Any two buckles can be directly fastened together, making the operation simple and convenient.

[0026] like Figure 3 As shown, both the first buckle body 10 and the second buckle body 20 may include a buckle seat 30. The front ends of the buckle seat 30 are respectively provided with two parallel and spaced high-position upright plates 31 and low-position upright plates 32. The front of the buckle seat 30 is provided with a vertical insert 33 in the middle between the high-position upright plates 31 and the low-position upright plates 32. The insert 33 and the high-position upright plates 31 and the low-position upright plates 32 respectively form two receiving channels 34 for the cage frame to be inserted. The end of the high-position upright plate 31 is provided with a hook 311 protruding inward and a hook body 321 protruding outward and capable of being fastened to the other hook 311.

[0027] In specific implementation, when the first buckle body 10 and the second buckle body 20 are fastened together, the hook 311 of the first buckle body 10 is engaged with the hook 321 of the second buckle body 20, and the hook 311 of the second buckle body 20 is engaged with the hook 321 of the first buckle body 10.

[0028] Among them, the insert 33 can ensure the alignment of the two fasteners in the horizontal and vertical directions when the first fastener 10 and the second fastener 20 are fastened together, which can prevent the adjacent tubes of the cage frame from being misaligned to the left and right, and the first fastener 10 and the second fastener 20 from being misaligned to the right and left, further improving the assembly stability of the cage.

[0029] Preferably, both the first buckle body 10 and the second buckle body 20 can be made of plastic. Plastic has the advantages of being lightweight, low-cost, and easy to process. Plastic also has a certain degree of elasticity, which can prevent structural interference during the installation and disassembly of the buckle and improve its durability for outdoor use.

[0030] like Figure 4 As shown, the outer surface of the hook 311 facing the insert 33 can be set as a first wedge surface 312, and the first wedge surface 312 is inclined outward from its top end to its bottom end.

[0031] Correspondingly, the outer surface of the hook body 321 away from the insertion piece 33 can be set as a second wedge surface 322 that slidably cooperates with another first wedge surface 312. The second wedge surface 322 is inclined outward from its top end to its bottom end.

[0032] Preferably, the buckle seat 30 is set as a square seat body, and the cross-sectional structure of the buckle seat 30 is in the shape of a Chinese character 'Ri'.

[0033] Furthermore, the two accommodating channels 34 of the first buckle body 10 and the two accommodating channels 34 of the second buckle body 20 are complementarily butted to form a cuboid structure when the first buckle body 10 and the second buckle body 20 are buckled. This embodiment can be applied to a 0.8 cm square tube. Of course, in other embodiments, the width of the accommodating channel 34 can be adjusted according to the width of the existing square tube, and this embodiment does not limit it.

[0034] As Figure 5 shown, both sides of the high-position vertical plate 31 are provided with first side baffles 35 that extend out of the hook 311 and are located below the hook 311. Both sides of the low-position vertical plate 32 are provided with second side baffles 36 that extend out of the hook body 321. The horizontal heights of the first side baffles 35, the second side baffles 36, and the insertion piece 33 are on the same horizontal line. When the first buckle body 10 and the second buckle body 20 are buckled to each other, the top of the first side baffle 35 of the first buckle body 10 abuts against the top of the second side baffle 36 of the second buckle body 20, the top of the insertion piece 33 of the first buckle body 10 abuts against the top of the insertion piece 33 of the second buckle body 20, and the top of the first side baffle 35 of the second buckle body 20 abuts against the top of the second side baffle 36 of the first buckle body 10.

[0035] Specifically, a strip-shaped hole 301 is formed through the side of the buckle seat 30 close to the high-position vertical plate 31 and is located between the two first side baffles 35. The strip-shaped hole 301 is beneficial for the high-position vertical plate 31 to turn outwards moderately, facilitating manual buckling or separation of the hook 311 during installation and disassembly.

[0036] Furthermore, the edges of the two ends of the buckle seat 30 connected to the outer side walls of the high-position vertical plate 31 and the low-position vertical plate 32 are all set with arc transitions. The edges of both sides of the buckle seat 30 and the edges of the connection parts of the buckle seat 30 with the outer side walls of the first side baffle 35 and the second side baffle 36 are all set with arc transitions.

[0037] Among them, the outer edges of the buckle seat 30 are all set with arc transitions, eliminating sharp edges and being able to protect users and pets from scratches.

[0038] As Figure 6As shown, during installation, by placing two adjacent square tubes of the cage frame into the two receiving channels 34 corresponding to the first buckle 10 and the second buckle 20 respectively, and then bringing the hooks 311 of the first buckle 10 and the hooks 321 of the second buckle 20 closer together and pressing them down, as well as pressing the hooks 311 of the second buckle 20 and the hooks 321 of the first buckle 100 together, the corresponding wedge surfaces can guide the hooks 311 and the hooks 321 to align. At this time, the high-position upright plate 31 can generate a certain elastic deformation outward and achieve reset when they are fastened together. This embodiment does not require the use of screws for installation, which enhances the connection strength, so that the cage can withstand greater external force after being assembled and fixed by multiple buckles, and is not easy to fall apart, ensuring the stability of the cage during use. It is especially suitable for pet cages. Of course, in other embodiments, it is also suitable for the installation and fixing of other cages.

[0039] During disassembly, simply apply a certain external force to the high-position upright plate 31 of the first buckle 10 or the second buckle 20 to separate the hook 311 and the hook body 321, and the two can be quickly disassembled, making it convenient to store, move or reassemble the cage, and meet the usage needs of consumers in different scenarios.

[0040] In summary, this utility model achieves bidirectional self-locking by using a first and second buckle body with identical structures. Users do not need to distinguish between left and right parts; any two buckles can be directly fastened together. Compared with traditional multi-specification buckles that use screws for fixing, it not only reduces the number of parts but also eliminates the need for screw installation, enabling quick, convenient, and secure cage assembly and fixing. It is simple to operate, improves disassembly and assembly efficiency, saves time and effort, and has low production costs. It is especially suitable for the installation and fixing of pet cages and is also applicable to the installation and fixing of other cages.

[0041] The above embodiments are preferred embodiments of the present utility model, but the embodiments of the present utility model are not limited to the above embodiments. Any changes, modifications, substitutions, combinations, or simplifications made without departing from the spirit and principle of the present utility model shall be considered equivalent substitutions and shall be included within the protection scope of the present utility model.
