[0027] The buckle body 10 includes an opening 11, a base 12, a connecting portion 13, a mounting hole 131, an internal thread 132, a slot 133, a positioning slot 134, a crossbar 14,

[0028] The mounting portion 20 includes a straight rod portion 21, an external thread portion 22, a head portion 23, a wrench groove 24, a buckle portion 25, a support portion 251, a hook portion 252, a long rod portion 26,

[0029] The webbing 30 and the webbing hole 40 . DETAILED DESCRIPTION

[0030] The following examples are provided to further explain and supplement the present invention and do not constitute any limitation to the present invention.

[0031] like Figure 1 to Figure 5As shown, the buckle of the present invention includes a buckle body 10. The main point of the present invention is that a mounting portion 20 for passing a webbing 30 is provided on the buckle body 10, and the mounting portion 20 is detachably connected to the buckle body 10, so that the webbing 30 in a ring shape can be sleeved on the mounting portion 20 and connected to the buckle body 10 without having to cut the webbing 30 or the buckle for disassembly and assembly.

[0032] like Figure 1 , Figure 3 As shown, the buckle body 10 can be a female buckle body or a male buckle body, and the present invention is not limited thereto.

[0033] The buckle body 10 is provided with an opening 11, and the mounting portion 20 is detachably connected to the opening 11 and encloses the opening 11 to form at least one webbing hole 40. The webbing hole 40 is in the shape of a through hole and has a continuous surrounding wall.

[0034] The opening 11 may be open (e.g. Figure 2 ), or it can be non-open (such as Figure 3 As shown), they are all in the form of through holes.

[0035] like Figure 1 , Figure 2 As shown, for an open opening portion 11 , after the mounting portion 20 is mounted at the opening portion 11 , the mounting portion 20 can close the opening of the opening portion 11 , thereby forming a non-open webbing hole 40 .

[0036] like Figure 3 , Figure 4 , Figure 5 As shown, for the non-open opening 11, it has a continuous surrounding wall. The opening 11 can be the original webbing hole of the buckle. When the mounting portion 20 is installed at the non-open opening 11, the mounting portion 20 can separate the original opening 11 into a plurality of non-open webbing holes 40. For example, one opening 11 is separated into two webbing holes.

[0037] The webbing hole 40 is used for the webbing 30 to pass through, and the mounting portion 20 is used for the webbing 30 to be wound around to bear the load force.

[0038] During installation, first remove the mounting part 20 from the buckle body 10, then pass the mounting part 20 on the ring-shaped closed webbing 30, and then install the mounting part 20 on the buckle body 10, and the webbing 30 can be installed on the buckle. In this way, by disassembling and assembling the mounting part 20, the ring-shaped closed webbing 30 (not a single-strand webbing) that has been sewn and fixed can be installed on the buckle without having to cut the webbing 30 for installation.

[0039] Further, the buckle body 10 includes a base portion 12 and a connecting portion 13 that are integrally formed or fixedly connected. Preferably, the base portion 12 and the connecting portion 13 are integrally formed.

[0040] The base part 12 is the main part of the buckle. For example, for a male buckle, the base part 12 is the main part with a locking tongue.

[0041] The connecting portion 13 is protrudingly disposed on the base portion 12 and is used for detachably connecting to the mounting portion 20 .

[0042] The shape of the connecting portion 13 is not limited, and its position can be set as needed. Usually, it is set at one end of the base portion 12. The connecting portion 13 is protrudingly arranged on the base portion 12, which means that the connecting portion 13 is not flush with at least a part of the end of the base portion 12. In this embodiment, the end of the base portion 12 is relatively flat, and the connecting portion 13 protrudes vertically from the end of the base portion 12.

[0043] The number of the connecting parts 13 can be set as needed. Usually, two connecting parts 13 can meet the requirements of the present invention. Of course, on this basis, it is also possible to set more than two connecting parts 13, and accordingly, multiple webbings 30 can be installed.

[0044] The connecting parts 13 are spaced apart from each other to form a space for the webbing 30 to pass through.

[0045] In some embodiments, Figure 1 , Figure 2 As shown, the end of the connecting portion 13 is a free end. At this time, an open opening 11 is formed between the connecting portion 13 and the base portion 12 .

[0046] In some embodiments, Figure 3 , Figure 4 As shown, the ends of the connecting portion 13 are connected by an integrally formed crossbar portion 14, and a non-open opening 11 is formed between the connecting portion 13, the base portion 12, and the crossbar portion 14. The crossbar portion 14 can be used as the mounting portion 20 in a conventional buckle.

[0047] The mounting portion 20 is detachably connected to the connecting portion 13. When the mounting portion 20 is mounted on the connecting portion 13, the mounting portion 20 is spaced apart from the base portion 12, so that a webbing hole 40 can be formed between the mounting portion 20, the base portion 12 and the connecting portion 13.

[0048] The following is a specific description with different embodiments:

[0049] Example 1

[0050] like Figure 1, Figure 2 As shown, the end of the connecting portion 13 is a free end, and an open opening 11 is formed between the connecting portion 13 and the base portion 12 .

[0051] The connecting portion 13 is respectively provided with mounting holes 131 , and at least one mounting hole 131 is provided with an internal thread 132 for threaded connection with the mounting portion 20 .

[0052] The mounting portion 20 is in the shape of a long rod, and at least a part of the mounting portion 20 is provided with an external thread matching the internal thread 132. The mounting portion 20 is inserted into the mounting hole 131 and forms a threaded connection with at least one mounting hole 131.

[0053] Through the threaded connection, the mounting portion 20 can be screwed onto the connecting portion 13 and can be screwed out, thereby forming a detachable connection between the mounting portion 20 and the connecting portion 13 .

[0054] Furthermore, the mounting portion 20 includes an integrally formed straight rod portion 21 , an external threaded portion 22 and a head portion 23 .

[0055] The head 23 and the external threaded portion 22 are disposed at both ends of the straight rod portion 21. The straight rod portion 21 can freely pass through the mounting hole 131. The head 23 cannot pass through the mounting hole 131. The external threaded portion 22 can be threadedly connected to the mounting hole 131 provided with the internal thread 132.

[0056] When in use, first pass the closed looped webbing 30 (i.e. the non-single-strand webbing 30 that has been sewn) through the webbing hole 40, then insert the mounting portion 20 into the mounting hole 131, and make the mounting portion 20 pass through the inside of the webbing 30, then make the external threaded portion 22 of the mounting portion 20 and the mounting hole 131 threadedly connected, so that the mounting portion 20 is transversely connected between the connecting portions 13, and the webbing 30 is sleeved on the mounting portion 20. In this way, the closed looped webbing 30 can be directly sleeved on the mounting portion 20 to achieve connection with the buckle body 10.

[0057] When the buckle needs to be removed, the mounting portion 20 only needs to be rotated so that the external thread portion 22 is no longer connected to the mounting hole 131 with the internal thread 132 , and the mounting portion 20 can be separated from the webbing 30 and the buckle body 10 .

[0058] Preferably, on the two connecting parts 13 in this embodiment, one mounting hole 131 is a smooth hole to facilitate the free passage of the mounting part 20 , and one mounting hole 131 is provided with an internal thread 132 , which is a hole with the internal thread 132 and is threadedly connected to the mounting part 20 .

[0059] When in use, the external threaded portion 22 of the mounting portion 20 is first passed through the mounting hole 131 of the light hole, and then inserted into the mounting hole 131 of the internal threaded portion 132 for threaded connection.

[0060] The mounting hole 131 of the light hole is configured as a through hole.

[0061] The mounting hole 131 with the internal thread 132 may be a through hole or a blind hole, and may be configured as required.

[0062] Furthermore, in order to facilitate the disassembly and assembly of the mounting portion 20 , a wrench groove 24 , such as a cross groove or a slotted groove, is provided on the head portion 23 , which facilitates the user to use a tool to rotate the mounting portion 20 for disassembly and assembly.

[0063] In this embodiment, the mounting portion 20 is inserted into the mounting hole 131 in a direction transverse to the connecting portion 13. The direction in which the mounting portion 20 is separated from the connecting portion 13 is called a separation direction. The separation direction is perpendicular or nearly perpendicular to the direction of the load force applied to the mounting portion 20 by the webbing 30. In this way, when the mounting portion 20 is not actively twisted, the mounting portion 20 can be used to bear a larger load, and the strength of the overall structure of the buckle will not be affected because the mounting portion 20 is detachably connected to the buckle body 10.

[0064] Example 2

[0065] like Figure 3 , Figure 4 , Figure 5 As shown, the ends of the connecting portion 13 are connected by a crossbar portion 14 , and a non-open opening portion 11 is formed between the connecting portion 13 , the crossbar portion 14 , and the base portion 12 .

[0066] The connecting portion 13 is provided with a slot 133, and correspondingly, the mounting portion 20 is provided with a buckle portion 25, which can be buckled with the slot 133, so that the mounting portion 20 can be detachably connected to the connecting portion 13. The mounting portion 20 is spaced apart from the base portion 12 to form the webbing hole 40.

[0067] In this embodiment, the slot 133 is disposed on two opposite side walls of the connecting portion 13 , and is a groove formed by partially concavely concave side walls of the connecting portion 13 , thereby forming a step structure on the side walls of the connecting portion 13 .

[0068] The mounting portion 20 includes an integrally formed long rod portion 26 , a support portion 251 and a hook portion 252 . The support portion 251 and the hook portion 252 form the buckle portion 25 and can be matched with the slot 133 .

[0069] The support portion 251 is protrudingly disposed on the long rod portion 26 and is relatively spaced. The support portion 251 extends in a cantilever shape, so it has a certain elastic deformation ability and can be squeezed and deviate from its basic position. The shape of the support portion 251 is not limited. In this embodiment, the support portion 251 is in a flat plate shape.

[0070] The hook portion 252 is disposed on a surface opposite to the support portion 251 and is used to be inserted into the slot 133. The hook portion 252 protrudes from the side wall of the support portion 251, so that a step structure is formed between the hook portion 252 and the support portion 251.

[0071] The shape of the hook portion 252 is not limited. In this embodiment, the hook portion 252 is in a rectangular block shape. In other embodiments, the hook portion 252 can also be configured to be in an oblique wedge shape to facilitate being inserted into the slot 133 .

[0072] Furthermore, in order to improve the structural strength, the support portion 251 is disposed at the proximal end of the long rod portion 26, rather than at the end position. Accordingly, a positioning groove 134 is disposed on the connecting portion 13. The positioning groove 134 is adjacent to the clamping groove 133 and is located on two adjacent wall surfaces of the connecting portion 13.

[0073] Preferably, the positioning groove 134 is provided on the front side of the connecting portion 13 , and the locking groove 133 is provided on the inner side surface of the connecting portion 13 adjacent to the front side.

[0074] The shape and size of the positioning groove 134 match the shape and size of the end of the long rod portion 26. The end of the long rod portion 26 can be embedded in the positioning groove 134, thereby overlapping the connecting portion 13 to bear the load.

[0075] When in use, the webbing 30 is passed through the opening 11, and then the webbing 30 is put on the mounting portion 20, and the position of the webbing 30 is adjusted so that the webbing 30 is located on the long rod portion 26 between the support portions 251, and then the mounting portion 20 is aligned with the positioning groove 134 and snapped into place; during the snapping process, the hook portion 252 first contacts the inner wall of the connecting portion 13, squeezing the support portion 251, causing the support portion 251 to undergo elastic deformation; when the hook portion 252 enters the slot 133, the support portion 251 is elastically reset, causing the buckle portion 25 to engage with the slot 133; when the buckle portion 25 is engaged with the slot 133, the end of the long rod portion 26 is also embedded in the positioning groove 134, thereby setting the mounting portion 20 on the buckle body 10.

[0076] Since a step structure is formed between the locking groove 133 and the side wall of the connecting portion 13 , it is difficult for the mounting portion 20 to be reversely detached from the connecting portion 13 without external force.

[0077] Normally, the separation direction of the mounting part 20 from the connecting part 13 is opposite to or transverse to the direction of the load force applied to the mounting part 20 by the webbing 30, which can hinder the separation of the mounting part 20 to a certain extent. Therefore, even if the mounting part 20 and the connecting part 13 are detachably connected by a snap-on structure, the mounting part 20 can still withstand a large load without affecting the load-bearing capacity of the buckle itself and reducing the strength of the buckle.

[0078] When the mounting portion 20 needs to be removed, a sharp tool can be inserted between the connecting portion 13 and the hook portion 252 to cause the supporting portion 251 to elastically deform and deflect inwardly. In this way, the hook portion 252 can be removed from the slot 133 and the mounting portion 20 as a whole can be removed from the connecting portion 13.

[0079] Example 3

[0080] The structure of this embodiment is basically the same as that of Embodiment 2, except that the end of the connecting portion 13 is a free end, and an open opening 11 is formed between the connecting portion 13 and the base portion 12 .

[0081] Example 4

[0082] The structure of this embodiment is basically the same as that of the first embodiment, except that the mounting holes 131 are all bare holes, and no internal threads are preset on the inner wall thereof. The external threaded portion 22 on the mounting portion 20 is configured as a self-tapping thread. When the external threaded portion 22 is screwed into the mounting hole 131 during use, the external threaded portion 22 can be matched with the mounting hole 131.

[0083] In the above embodiments, the structures of different embodiments can be applied to the same buckle or to different buckles; they can be applied to the female buckle or the male buckle at the same time, and they can be set according to actual conditions.

[0084] For example, the male buckle may adopt the structure of embodiment 2, and the female buckle may adopt the structure of embodiment 1. Alternatively, both the male buckle and the female buckle may adopt the structure of embodiment 1. Alternatively, the female buckle may adopt the structure of embodiment 2.

[0085] Thus, the buckle of the present invention is formed, and its mounting portion 20 is detachably arranged on the buckle body 10, rather than being integrally formed with the buckle body 10. Therefore, the user can directly install the ring-shaped closed webbing 30 on the buckle without having to cut the original webbing 30 or the original buckle. In this way, the user can conveniently replace the buckle according to actual needs, expand the function of the webbing 30, etc.

[0086] Although the present invention is disclosed through the above embodiments, the scope of the present invention is not limited thereto, and the above components may be replaced with similar or equivalent elements known to those skilled in the art without departing from the concept of the present invention.
