[0002] Fasteners generally include a male fastener and a female fastener. The male fastener and the female fastener can be locked together and can be opened. Among them, both the male fastener and the female fastener can be connected to the webbing. In this way, through the male fastener and the female fastener, a detachable connection between different objects can be realized. For example, for the fastener on a helmet, the male fastener and the female fastener are respectively connected to different helmet straps, and the helmet can be conveniently opened for wearing through the male fastener and the female fastener. Another example is that on a baby stroller, the safety belts are connected through the male fastener and the female fastener. Such as these, in daily life, in many items, it is necessary to connect the webbing to the fastener to achieve an openable connection.

[0003] To facilitate the connection of the webbing, whether it is a male fastener or a female fastener, an installation part is provided thereon. A webbing hole is provided on the installation part through which the webbing can pass, and the installation part can make the webbing wind around it to bear the load. In the existing fasteners, the installation part is usually integrally formed with the plastic shell of the male fastener or the female fastener. When installing the webbing, only a single-strand webbing that is not sewn together can be passed through the webbing hole, and then wound around the installation part to make the single-strand webbing overlap, and then sewn at the overlapping part, so that the single-strand webbing becomes a double-strand webbing and is fixedly connected to the male fastener or the female fastener.

[0004] In practice, users sometimes need to replace or improve the structure of the fastener or the webbing. For example, the fastener on a baby stroller is inconvenient to operate or has poor quality, and the user wants to replace it with a more convenient or better-quality fastener by himself; another example is that the user wants to add a fastener to the webbing to achieve more functions. If the user needs to replace the male fastener or the female fastener, usually the webbing needs to be cut, then a new fastener is replaced, and then the webbing is sewn to make the disconnected webbing re-sewn into a ring-shaped closed double-strand webbing.

[0005] Obviously, this structure is not conducive to users replacing the fastener, and moreover, cutting the original webbing not only affects the appearance but also affects the firmness. Summary of the Utility Model

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

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

[0031] like Figures 1 to 5As shown in the figure, the buckle of the present utility model includes a buckle body 10. The main point of the present utility model is that an installation part 20 for threading a webbing 30 is provided on the buckle body 10. The installation part 20 is detachably connected to the buckle body 10, so that the ring-shaped and closed webbing 30 can be sleeved on the installation part 20 to be connected to the buckle body 10, without having to cut the webbing 30 or the buckle for disassembly and assembly.

[0032] As Figure 1 , Figure 3 shown, the buckle body 10 can be a female buckle body or a male buckle body, and the present utility model does not limit it.

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

[0034] The opening part 11 can be open (as Figure 2 shown) or non-open (as Figure 3 shown), and it is in the shape of a through hole.

[0035] As Figure 1 , Figure 2 shown, for the open opening part 11, after the installation part 20 is installed at the opening part 11, the installation part 20 can close the open part of the opening part 11, thereby forming a non-open webbing hole 40.

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

[0037] The webbing hole 40 is for the webbing 30 to pass through, and the installation part 20 is for the webbing 30 to wind around to bear the load force.

[0038] During installation, first detach the installation part 20 from the buckle body 10, then thread the installation part 20 through the ring-shaped and closed webbing 30, and then install the installation part 20 on the buckle body 10, then the webbing 30 can be installed on the buckle. In this way, by disassembling and assembling the installation part 20, the ring-shaped and closed webbing 30 (not a single-strand webbing) that has been sewn and fixed originally 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 portion 12 is the main part of the buckle. For example, for a male buckle, the base portion 12 is the main part provided with a locking tongue.

[0041] The connecting portion 13 protrudes from the base portion 12 and is used for detachably connecting the mounting portion 20.

[0042] The shape of the connecting portion 13 is not limited, and its position can be set as needed. Generally, it is provided at one end of the base portion 12. The connecting portion 13 protruding from the base portion 12 means that at least a partial position of the connecting portion 13 is not flush with 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 perpendicularly from the end of the base portion 12.

[0043] The number of the connecting portions 13 can be set as needed. Generally, two connecting portions 13 can meet the requirements of the present invention. Of course, on this basis, it is also possible to provide more than 2 connecting portions 13, and correspondingly, it can be used to install multiple webbings 30.

[0044] The connecting portions 13 are spaced opposite to each other, thereby forming a space through which the webbing 30 can be threaded.

[0045] In some embodiments, as Figure 1 、 Figure 2 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, as Figure 3 、 Figure 4 shown, the ends of the connecting portions 13 are connected by an integrally formed crossbar portion 14. At this time, 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 traditional 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 from the base portion 12. In this way, 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] Embodiment 1

[0050] As shown Figure 1 , Figure 2 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] Mounting holes 131 are respectively provided on the connecting portion 13, and internal threads 132 are provided in at least one of the mounting holes 131 for threaded connection with the mounting portion 20.

[0052] The mounting portion 20 is in the shape of a long rod, and external threads matching the internal threads 132 are provided at least partially thereon. 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 threaded connection, the mounting portion 20 can be helically mounted on the connecting portion 13 and can be helically removed, so that a detachable connection is formed 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 thread portion 22, and a head portion 23.

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

[0056] In use, first pass the annularly closed 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, and then make the external thread portion 22 of the mounting portion 20 threadedly connected to the mounting hole 131, so that the mounting portion 20 is horizontally connected between the connecting portions 13, and the webbing 30 is sleeved on the mounting portion 20. In this way, the annularly closed 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, just rotate the mounting portion 20 to disconnect the external thread portion 22 from the mounting hole 131 provided 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 portions 13 in this embodiment, one mounting hole 131 is a clearance hole to facilitate the free passage of the mounting portion 20, and one mounting hole 131 is provided with an internal thread 132, which is an internal thread 132 hole and is threadedly connected to the mounting portion 20.

[0059] In use, first pass the external thread portion 22 of the mounting portion 20 through the mounting hole 131 of the light hole, and then insert it into the mounting hole 131 of the internal thread 132 hole for threaded connection.

[0060] Among them, the mounting hole 131 of the light hole is set as a through hole.

[0061] The mounting hole 131 provided with the internal thread 132 can be a through hole or a blind hole, which can be set according to needs.

[0062] Furthermore, to facilitate the disassembly and assembly of the mounting portion 20, a wrenching groove 24 is provided on the head portion 23, for example, a cross groove, a slotted groove, etc., 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 along 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 the separation direction. The separation direction is perpendicular or nearly perpendicular to the direction of the load force applied by the webbing 30 to the mounting portion 20. In this way, when the mounting portion 20 is not actively screwed, the mounting portion 20 can be used to bear a large 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] Embodiment 2

[0065] As Figure 3 、 Figure 4 、 Figure 5 shown, the end of the connecting portion 13 is connected by a cross bar portion 14, and a non-open opening portion 11 is formed between the connecting portion 13, the cross bar portion 14, and the base portion 12.

[0066] Card slots 133 are respectively provided on the connecting portion 13. Correspondingly, buckle portions 25 are respectively provided on the mounting portion 20. The buckle portions 25 can be engaged with the card slots 133, so that the mounting portion 20 is 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 card slots 133 are provided on opposite side walls of the connecting portion 13. They are grooves formed by local side walls of the connecting portion 13 being recessed inward, so that a stepped structure is formed on the side wall 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 to cooperate with the card slot 133.

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

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

[0071] The shape of the hook part 252 is not limited. In this embodiment, the hook part 252 is in a rectangular block shape. In other embodiments, the hook part 252 can also be provided in a wedge shape to facilitate insertion into the card slot 133.

[0072] Furthermore, to improve the structural strength, the supporting part 251 is provided at the proximal end of the long rod part 26 instead of the end position. Correspondingly, a positioning slot 134 is provided on the connecting part 13. The positioning slot 134 is adjacent to the card slot 133 and is located on two adjacent wall surfaces of the connecting part 13.

[0073] Preferably, the positioning slot 134 is provided on the front surface of the connecting part 13, and the card slot 133 is provided on the inner side surface of the connecting part 13 adjacent to the front surface.

[0074] The shape and size of the positioning slot 134 match the shape and size of the end of the long rod part 26. The end of the long rod part 26 can be embedded in the positioning slot 134, so as to be lapped on the connecting part 13 to bear the load.

[0075] During use, pass the webbing 30 through the opening 11, then put the webbing 30 on the mounting part 20, and adjust the position of the webbing 30 so that the webbing 30 is on the long rod part 26 between the supporting parts 251, and then align the mounting part 20 with the positioning slot 134 and insert it; during the clamping process, the hook part 252 first contacts the inner side wall of the connecting part 13 and squeezes the supporting part 251, causing the supporting part 251 to undergo elastic deformation; when the hook part 252 enters the card slot 133, the supporting part 251 elastically resets, so that the buckle part 25 is engaged with the card slot 133; when the buckle part 25 is engaged with the card slot 133, the end of the long rod part 26 is also embedded in the positioning slot 134, so as to set the mounting part 20 on the buckle body 10.

[0076] Since a stepped structure is formed between the card slot 133 and the side wall of the connecting part 13, therefore, without external force, it is difficult for the mounting part 20 to be disengaged from the connecting part 13 in the reverse direction.

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

[0078] When it is necessary to remove the mounting portion 20, a sharp tool can be inserted between the connecting portion 13 and the hook portion 252 to cause the support portion 251 to elastically deform and shift inward. In this way, the hook portion 252 can be removed from the card slot 133, and the entire mounting portion 20 can be taken out from the connecting portion 13.

[0079] Embodiment 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 portion 11 is formed between the connecting portion 13 and the base portion 12.

[0081] Embodiment 4

[0082] The structure of this embodiment is basically the same as that of Embodiment 1, except that the mounting holes 131 are all through holes and no internal threads are preset on their inner walls. The external thread portion 22 on the mounting portion 20 is set in a self-tapping thread form. When in use, when the external thread portion 22 is screwed into the mounting hole 131, the external thread portion 22 can cooperate 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 at the same time or to the male buckle at the same time, and can be set according to actual situations.

[0084] For example, the male buckle can adopt the structure of Embodiment 2, and the female buckle can adopt the structure of Embodiment 1. Or, both the male buckle and the female buckle can adopt the structure of Embodiment 1. Or, the female buckle adopts the structure of Embodiment 2.

[0085] Thus, the buckle of the present utility model is formed. Its mounting portion 20 is detachably arranged on the buckle body 10 instead of being integrally formed with the buckle body 10. Therefore, the user can directly install the annularly closed webbing 30 on the buckle without having to cut the original webbing 30 or cut the original buckle. In this way, the user can conveniently replace the buckle and expand the functions of the webbing 30 according to actual needs.

[0086] Although the present utility model has been disclosed through the above embodiments, the scope of the present utility model is not limited thereto. Under the condition of not deviating from the concept of the present utility model, the above components can be replaced by similar or equivalent elements known to those skilled in the art.
