Description

Technical Field

[0001] The present invention relates to a push buckle, in particular to a female buckle whose buckling portion is buckled into a limited space of a male buckle in a vertical direction, and through the elastic restoring force of an elastic body, a sliding piece in the male buckle is inserted into the buckling portion of the female buckle, so that the male and female buckles can concentrate the tensile force against the horizontal direction without being separated. Background Art

[0002] Most of the front buckles used today are male and female front buckles, and the uses of front buckles are varied. Most of them are wound with ropes and can be used for shoe buckles, backpacks, suitcases, shoulder straps, backpack front buckles or other items that need ropes to fix. Please refer to Fig.17 As shown, it is a three-dimensional exploded view of the existing male and female front buckles. It can be clearly seen from the figure that this existing front buckle mainly has elastic arms A1 on both sides of the male buckle A, and a rod body A2 is provided between the two elastic arms A1, and an opening B1 is provided at the front end of the female buckle B, and a guide rail B2 is provided in the opening B1, so that the elastic arm A1 and the rod body A2 of the male buckle A can be pushed in from the opening B1 of the female buckle B, and the rod body A2 of the male buckle A is aligned with the guide rail B2 of the female buckle B. After being pushed in, the buckling block A3 at the end of the elastic arm A1 can be inserted into the side holes B3 on both sides of the female buckle B, and the notch A4 formed by the turning surface between the buckling block A3 and the elastic arm A1 is buckled on the edge wall B4 of the side hole B3 to form a positioning.

[0003] However, although the male and female buckles mentioned above can achieve the buckling effect, they still have the following imperfections:

[0004] 1. The existing front buckle is horizontally buckled with each other. Because the buckling structure between the male and female buckles A and B must withstand horizontal tension, when excessive tension is generated, it is easy for the male and female buckles A and B to be directly separated in the horizontal direction (i.e., separated in the buckling direction), which further highlights that there is still room for improvement in the structure of the front buckle.

[0005] 2. The above-mentioned existing male buckle A is only used as the side hole B3 of the hook buckle female buckle B through two elastic arms A1 and the buckling block A3 at the end. If relying on this thin elastic arm A1, it is easy to cause the overall buckling force to be too weak, and the buckling force is dispersed on the left and right sides. Under the load and pulling of the rope, it is easy for excessive force to directly damage the elastic arm A1, causing the elastic arm A1 to deform or even break; and this structural design may cause the elastic arm A1 to be directly detached because the buckling block A3 of the elastic arm A1 is accidentally pressed by external force or the buckling is not airtight.

[0006] 3. When the above-mentioned existing male buckle A is pushed into the female buckle B, it is very easy for the two elastic arms A1 of the male buckle A and the central rod body A2 to be misaligned because they cannot completely align with the guide rail B2 in the opening B1 of the female buckle B, which causes inconvenience to the user when performing the buckling action, causing the elastic arms A1 and the rod body A2 to be easily damaged, resulting in bending deformation and breakage.

[0007] 4. The elastic arm A1 and the rod body A2 of the existing male buckle A are both suspended and extended, and the buckle block A3 extending from the end of the elastic arm A1 is in the shape of an inverted hook. When the male buckle A is not fastened, the buckle block A3 at the end of the elastic arm A1 is very easy to hook onto clothes or other foreign objects, resulting in breakage or deformation.

[0008] 5. The existing male buckle A needs to be additionally provided with a rod body A2, and the matching tolerance between the male buckle A and the female buckle B must also be more rigorous and precise, which easily leads to an increase in the unqualified rate of the finished product.

[0009] Therefore, how to solve the above existing problems and deficiencies is the direction that the relevant manufacturers engaged in this industry are eager to study and improve. Summary of the invention

[0010] Therefore, in view of the above problems and deficiencies, the inventor has collected relevant information, conducted multiple evaluations and considerations, and based on his many years of experience in this industry, through continuous trials and modifications, he finally designed this new patent for the push-button.

[0011] To achieve the above object, the technical solution adopted by the present invention is:

[0012] A push buckle, comprising a female buckle and a male buckle, characterized in that:

[0013] The female buckle is provided with a docking portion having a docking space, a buckling portion is convexly provided on the bottom surface of the docking space, and a combining portion is provided on the outer side of the docking portion;

[0014] The male buckle is movably docked in the docking space of the female buckle, and the male buckle includes a hollow body and a push piece that moves back and forth in the accommodating space of the hollow body. An opening is provided at the horizontal hollow part of the body, and a positioning piece is provided below the opening. The positioning piece forms a docking hole hollowed out downwardly inwardly, and a joint portion is provided on the outer side of the body of the opening of the accommodating space. The operating portion of the push piece is exposed outside the accommodating space, and a limiting space aligned with the docking hole is formed on the push piece, an elastic space is provided on the rear side of the limiting space, and a horizontal buckle hook extending toward the limiting space is provided at the bottom of one side of the push piece, and an elastic body is provided between the body of the male buckle and the stop block set up by the push piece.

DETAILED DESCRIPTION

[0043] In order to achieve the above-mentioned purpose and effect, the technical means and structures, implementation methods, etc. adopted by the present invention are illustrated in detail with reference to the preferred embodiments of the present invention, and their features and functions are as follows for complete understanding.

[0044] See also Figure 1 , Figure 2 , Figure 3 , Figure 4 As shown, it is a three-dimensional appearance diagram, a three-dimensional exploded diagram, a three-dimensional exploded diagram from another perspective, and a side cross-sectional diagram of the elastic body of the male buckle push piece when limiting the position of the first preferred embodiment of the present invention. It can be clearly seen from the figures that the present invention includes a female buckle 1 and a male buckle 2, wherein the female buckle 1 of the present invention is a docking portion 11, a tongue piece 12 and a connecting portion 13 having a docking space 110, and the docking portion 11 is formed with two side walls 113 and a buckling portion 111 protruding upward from the inner bottom surface of the two side walls 113, and a buckling hole 1111 is formed on the inner side of the vertical surface of the buckling portion 111, and a slightly raised recess 112 and a tongue piece 12 extending a distance are provided on the front and rear sides of the buckling portion 111, and a raised abutment block 121 is formed on the surface of the tongue piece 12, and the outer side of the recess 112 is a connecting portion 13 for passing the rope 3 and winding and positioning.

[0045] The male buckle 2 includes a hollow body 21 and a push piece 22. A accommodating space 210 is provided in the horizontal hollow of the body 21, and a positioning piece 212 is provided below the opening of the accommodating space 210. The positioning piece 212 is formed with a downwardly hollowed-out docking hole 211 inwardly, and a stopper 213 turning upward is provided on the bottom surface of the rear side of the accommodating space 210, and a joint portion 214 for passing a rope 3 around and winding is provided on the other side of the body 21 of the accommodating space 210. In addition, a one-piece push piece 22 is assembled in the accommodating space 210 of the body 21, and the operating portion 225 is exposed above the positioning piece 212, and a limited space 2201 and an elastic space 2202 are formed on the push piece 22. A push block 224 with an inclined surface inclined from bottom to top toward the limit space 2201 is provided on one side of 22 near the operating portion 225, and a horizontal hook 221 extending toward the limit space 2201 is provided at the bottom of the other side, and the elastic space 2202 is close to the position of the hook 221 and extends backward to form an S-shaped suspended elastic body 222, and a column 2221 is protruding downward on both sides of the last turning point of the elastic body 222 in the suspended direction, and a horizontal stop block 223 is provided at a distance on the rear side of the elastic body 222, and a guide slope 2231 is provided at the bottom of the stop block 223, and a coupling rod 226 is provided at a distance on the rear side of the stop block 223, and a pull tab 2261 is wound around and positioned on the coupling rod 226.

[0046] Therefore, when the push piece 22 of the male buckle 2 is to be assembled to the main body 21, the push piece 22 of the male buckle 2 is first pushed in the direction of the accommodating space 210 of the main body 21, and the guide slope 2231 of the stop block 223 will push and pass over the stop portion 213, so that the stop portion 213 can be positioned between the stop block 223 of the push piece 22 and the column 2221 of the elastic body 222, and the operating portion 225 is exposed above the positioning piece 212, so that the elastic body 222 of the push piece 22 can be horizontally reset when pushing or not pushing the stop portion 213 of the main body 21, and the overall assembly of the male buckle 2 of the present invention can be completed.

[0047] Please continue reading Figure 5 , Figure 6 , Figure 7 , Figure 81, 2 and 3. As shown in FIG. 2, it is a side view cross-sectional view before the push piece is pushed, a side view cross-sectional view when the push piece is pushed (I), a side view cross-sectional view when the push piece is pushed (II), and a side view cross-sectional view after the push piece is pushed. It can be clearly seen from the figure that when the female buckle 1 and the male buckle 2 are to be assembled, the user's finger pushes the operating portion 225 of the push piece 22 to slide backward a certain distance in the accommodating space 210 of the body 21, and the elastic body 222 is squeezed and deformed, and the limiting space 2201 of the push piece 22 is aligned with the docking hole 211, so that the buckling portion 111 of the female buckle 1 can be inserted into the limiting space 2201 of the male buckle 2 from bottom to top. During the pushing process, the upper inclined surface of the buckling portion 111 is against the inclined surface of the push block 224, and slides into the upper part of the buckle hook 221 along the inclined surface of the push block 224, and the male buckle 222 is pushed into the upper part of the buckle hook 221. The main body 21 of the buckle 2 is positioned between the two side walls 113 to prevent shaking. At this time, the user can release the push piece 22, and the stop part 213 can be pushed by the restoring elastic force of the elastic body 222 when it is not squeezed to restore the push piece 22 to its position. The buckle hook 221 of the push piece 22 is buckled into the buckle hole 1111 of the buckle part 111 to form a stable position. The above method can concentrate the horizontal pulling force of the buckle hook 221 of the push piece 22 in the buckle hole 1111 of the buckle part 111 through the elastic restoring force of the elastic body 222 to form a locking position. The user needs to apply a specific force to push the push piece 22 away, so that the female buckle 1 and the male buckle 2 can be vertically buckled in or disengaged, which can solve the defect of the existing female buckle 1 and the male buckle 2 being disengaged due to accidental touch, so as to achieve the effects of simple operation, reliable buckling and reliable action.

[0048] However, when the female buckle 1 and the male buckle 2 are to be separated, the user first pushes the operating portion 225 of the push piece 22 with his finger to slide backward a certain distance in the accommodating space 210 of the main body 21, and then the hook 221 of the push piece 22 begins to separate from the locking hole 1111 of the locking portion 111, and the inclined surface of the push block 224 begins to push against the guide surface above the locking portion 111, so that the male buckle 2 moves toward the engaging portion 214 as a whole, thereby causing the female buckle 1 and the male buckle 2 to separate vertically, thereby achieving the effect of simple operation and reliable action.

[0049] In addition, when the female buckle 1 and the male buckle 2 of the present invention are to be separated, the user can also use the pull tab 2261 on the coupling rod 226 to pull the hook 221 of the push plate 22 out of the coupling hole 1111 of the coupling portion 111, and the inclined surface of the push block 224 begins to push against the guide surface above the coupling portion 111, so that the male buckle 2 moves toward the coupling portion 214 as a whole, thereby causing the female buckle 1 and the male buckle 2 to separate vertically, so as to achieve the effect of simple operation and reliable action.

[0050] Please continue reading Fig. 9As shown, it is a three-dimensional appearance diagram of the second preferred embodiment of the present invention. In the first preferred embodiment of the present invention, the joint portion 214 of the male buckle 2 is provided with a rope 3 for passing through and positioning by a perforation method. However, in actual application, the male buckle 2 can also be provided with two joint portions 214 at different angles to provide two ropes 3 for passing through and positioning by a perforation method.

[0051] Please continue reading Fig.10 As shown, it is a three-dimensional appearance diagram of the third preferred embodiment of the present invention. In the first preferred embodiment of the present invention, the coupling portion 13 of the female buckle 1 is provided with a rope 3 for passing through and positioning by a perforation method. However, in actual application, a hollow and V-shaped angled coupling portion 214 may also be provided on the outer side of the female buckle 1, and a rope 3 may be passed through and positioned on both sides of the V-shaped angle of the coupling portion 214.
