[0032] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0033] In order to enable those skilled in the art to better understand the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0034] In the description of the present invention, it is necessary to understand that the terms "upper", "lower", "bottom" and "top" etc. indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the position or element referred to must have a specific orientation, be constructed and operate in a specific orientation, and therefore should not be understood as a limitation of the present invention.

[0035] The utility model aims to provide a metal buckle which has a simple structure and is easy to assemble.

[0036] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0037] See also Figures 1 to 6 The present embodiment provides a metal buckle that can be assembled at one time, including: a first buckle surface 100 and a second buckle surface 200 that are buckled with each other, the first buckle surface 100 is a shell structure, and a plurality of first buckle parts 110 are arranged inside it, the second buckle surface 200 is a plate structure, and its cross-sectional shape matches the first buckle surface 100, and a plurality of second buckle parts 210 that can be snapped with the first buckle parts 110 are arranged on the lower side of the second buckle surface 200.

[0038] Specifically, the metal buckle provided in the present embodiment is used in conjunction with a first buckle surface 100 and a second buckle surface 200, wherein the first buckle surface 100 is a shell structure with a cavity inside, and the second buckle surface 200 is buckled at the shell opening of the first buckle surface 100, so that the two form a whole; it should be noted that the shape of the first buckle surface 100 can be selected according to actual needs, and the shape of the second buckle surface 200 needs to be consistent with the first buckle surface 100, so that the two can just form a whole; the first buckle surface 100 and the second buckle surface 200 are one-time buckled by a first buckle portion 110 and a second buckle portion 210, and the first buckle portion 110 The second buckle surface 200 is arranged inside the cavity of the first buckle surface 100, and the second buckle surface 200 is a plate-like structure, and a second buckle portion 210 is arranged at the corresponding position thereof. When the first buckle portion 110 and the second buckle portion 210 are matched together, the buckle of the two can be completed by applying pressure. It should be noted that the buckle of the two is irreversible. After the buckle is completed, the two cannot be separated without destroying the first buckle surface 100 and the second buckle surface 200. In addition, in order to increase the stability of the buckle of the first buckle surface 100 and the second buckle surface 200, a plurality of first buckle portions 110 and the same number of second buckle portions 210 are arranged. Of course, the specific number of buckle portions can be selected according to actual needs. It should be noted that the metal buckle provided in this embodiment is made of a ductile metal, and the specific metal can be selected according to actual conditions.

[0039] When using the metal buckle provided in this embodiment, it is only necessary to align the first buckle portion 110 of the first buckle surface 100 and the second buckle portion 210 on the second buckle surface 200, and apply external force to squeeze, so as to complete the buckle; with such a configuration, this embodiment uses fewer components to make the overall weight lighter and the production efficiency higher, and after the buckle is completed, no other components are leaked, making the fastener more beautiful as a whole; in addition, the assembly of this embodiment is also simpler and more labor-saving.

[0040] In this embodiment, the first buckling portion 110 includes: a snap-fit ​​inner cylinder 111 and a protrusion 113; the snap-fit ​​inner cylinder 111 is a cylindrical structure with a circular cross-section, vertically arranged at the bottom inside the first buckling surface 100, and the snap-fit ​​inner cylinder 111 is provided with a first cavity 112; the protrusion 113 is arranged at the bottom of the first cavity 112, and the protrusion 113 is provided with an arc surface.

[0041] See also Figure 5 Specifically, the snap-fit ​​inner cylinder 111 is a cylindrical structure, which is vertically arranged at the bottom of the cavity of the first buckle surface 100, so that it is convenient to cooperate with the second buckle part 210. In addition, a cylindrical first cavity 112 is provided inside the snap-fit ​​inner cylinder 111, and a convex point 113 with an arc-shaped structure is provided in the first cavity 112. The first cavity 112 will accommodate the second buckle part 210 extending therein, and the second buckle part 210 will be deformed under the joint action of external force and the convex point 113.

[0042] On the basis of the above embodiment, the second buckling portion 210 includes: a clamping outer cylinder 211 and a clamping column 213; the clamping outer cylinder 211 is a cylindrical structure with a circular cross-section, which is vertically arranged on the second buckling surface 200, and the second cavity 212 inside the clamping outer cylinder 211 opens and gradually expands in the direction away from the second buckling surface 200, and the clamping outer cylinder 211 is used to be sleeved on the outer periphery of the clamping inner cylinder 111 to force the top of the clamping inner cylinder 111 to be squeezed and bent inwardly; the clamping column 213 is arranged at the bottom of the second cavity 212, and the clamping column 213 is inserted into the first cavity 112 when the clamping outer cylinder 211 is sleeved on the outer periphery of the clamping inner cylinder 111, and the free end of the clamping column 213 is provided with a third cavity 214 recessed inwardly.

[0043] Furthermore, when the first buckle portion 110 and the second buckle portion 210 cooperate, the clamping outer cylinder 211 is sleeved on the outer circumference of the clamping inner cylinder 111, and the clamping column 213 extends into the clamping inner cylinder 111, and the third cavity 214 provided at the lower end of the clamping column 213 abuts against the top of the protrusion 113; it should be noted that the space between the clamping outer cylinder 211 and the clamping column 213 is the second cavity 212, and the inner wall of the second cavity 212 is an inclined surface, as shown in FIG. Figure 4 As shown, the second cavity 212 opens and expands in the downward direction; in this way, under the pressure of external force, the clamping inner tube 111 is clamped in the second cavity 212, and the side wall at the top opening of the clamping inner tube 111 will bend inward under the action of the inclined surface. At the same time, the clamping column 213 is also deformed at its end under the action of external force and the protrusion 113, that is, the third cavity 214 is squeezed and expanded by the protrusion 113; in this way, the opening of the clamping inner tube 111 becomes smaller, and the lower end of the clamping column 213 expands, so that the first buckle surface 100 and the second buckle surface 200 can be firmly buckled together.

[0044] On the basis of the above embodiment, the inner wall of the second cavity 212 is an inwardly convex arc surface, so that when the first buckle surface 100 and the second buckle surface 200 are not squeezed by external force, a gap is left between the clamping inner cylinder 111 and the clamping outer cylinder 211.

[0045] Specific as Figure 3 and Figure 6 As shown, the inner wall of the second cavity 212 is arranged as a protruding arc-shaped inclined surface in the box, which can more conveniently squeeze the side wall of the top of the clamping inner cylinder 111, and the protruding curvature can make the top of the clamping inner cylinder 111 bend inward to a greater extent, thereby preventing the clamping column 213 from detaching from the first cavity 112; of course, the part of the second cavity 212 located above the protruding part is smaller than the wall thickness of the clamping inner cylinder 111, which is also to increase the degree of inward bending of the top of the clamping inner cylinder 111; in addition, the side wall of the clamping outer cylinder 211 is arranged to be thicker near the second buckle surface 200, which can also increase the strength of the second buckling part 210, thereby preventing the clamping outer cylinder 211 from being broken by the clamping inner cylinder 111.

[0046] On the basis of the above embodiment, the axial length of the clamping column 213 is greater than the axial length of the clamping outer cylinder 211 .

[0047] Specifically, when the first buckling portion 110 and the second buckling portion 210 cooperate, the clamping column 213 needs to extend into the first cavity 112 and needs to abut against the protrusion 113, so that under the pressure of external force, the clamping inner cylinder 111 can move in the second cavity 212, and the clamping column 213 is deformed at its end due to being abutted by the protrusion 113.

[0048] On the basis of the above embodiment, the outer circumference of the top of the clamping inner cylinder 111 is provided with a concave surface matching with the inner wall of the second cavity 212 .

[0049] Specific as Figure 5 and Figure 6 As shown, the outer circumference of the top of the clamping inner cylinder 111 is provided with a concave surface, which can cooperate with the inner wall of the second cavity 212, so as to bend inward when subjected to pressure to buckle the clamping column 213 of the first cavity 112.

[0050] In this embodiment, the inner wall of the third cavity 214 is an arc-shaped surface, so that when the first buckle surface 100 and the second buckle surface 200 are not squeezed by external force, a gap is left between the protrusion 113 and the clamping column 213 .

[0051] It can be understood that the inner wall of the third cavity 214 is an arc-shaped surface, but the arc-shaped surface cannot completely fit with the protrusion 113, and a gap is left between the two. Only when the inner wall of the third cavity 214 is squeezed by external force will it fit with the protrusion 113. This arrangement is to enable the lower end of the clamping column 213 to expand and deform under the cooperation of the protrusion 113.

[0052] In some embodiments, a groove is disposed at the bottom of the third cavity 214, and the cross section of the groove is triangular.

[0053] Specific as Figure 6 As shown, the arrangement of the slot is conducive to the expansion of the bottom end of the snap-fit ​​column 213 , which can reduce the difficulty of snapping the first snap-fit ​​surface 100 and the second snap-fit ​​surface 200 .

[0054] In this embodiment, the first buckle portion 110 and the first buckle surface 100 are integrally formed by die-casting, and the second buckle portion 210 and the second buckle surface 200 are integrally formed by die-casting.

[0055] It can be understood that the first buckle surface 100 and the second buckle surface 200 are both integrated structures. This arrangement can maximize the structural strength of both and reduce the difficulty of production.

[0056] In this embodiment, the first buckle surface 100 and the second buckle surface 200 are both made of zinc alloy.

[0057] It can be understood that zinc alloy has good ductility and strength. In this embodiment, the material of the first buckle surface 100 and the second buckle surface 200 is preferably zinc alloy. Of course, other materials can also be selected according to actual conditions.

[0058] It should be noted that, in this specification, relational terms such as first and second are merely used to distinguish one entity from other entities, but do not necessarily require or imply any actual relationship or order between these entities.

[0059] The various embodiments in this specification are described in a progressive manner, and each embodiment focuses on the differences from other embodiments. The same or similar parts between the various embodiments can be referenced to each other.

[0060] The above is a detailed introduction to the embodiments provided by the utility model. This article uses specific examples to illustrate the principles and implementation methods of the utility model. The description of the above embodiments is only used to help understand the method and core ideas of the utility model. It should be pointed out that for ordinary technicians in this technical field, without departing from the principles of the utility model, the utility model can also be improved and modified, and these improvements and modifications also fall within the scope of protection of the claims of the utility model.
