Description

Technical Field

[0001] The invention relates to the technical field of connecting components, and in particular to an anti-shaking splicing zipper head assembly. Background Art

[0002] A zipper is a connector that combines or separates items by means of continuously arranged chain teeth. It is widely used in clothing, bags, tents and other items. Generally speaking, a zipper is equipped with a slider and a pull tab connected to the front end of the slider. The rear of the slider has two opening and closing edges arranged in a "human" shape, and a connecting edge is provided in the middle of the front upper surface in a forward and backward direction. The rear of the connecting edge has a triangle that matches the opening and closing edge. When in use, the two chain teeth are stuck in the two guide grooves formed by the opening and closing edges and the triangle. As the slider moves forward and backward, the two chain teeth can be locked together or separated. The front end of the pull tab is connected to the front end of the slider, which is convenient for the user to pinch and then pull the slider to move forward and backward. The common defect is that the connection between the pull tab and the slider is relatively loose, the pull tab is very easy to move, especially easy to shake left and right, and in some cases the pull tab will get stuck, which is not convenient enough. For this reason, many people in the industry have made many improvements to the connection between the pull tab and the slider, but the improvements often make the assembly of the pull tab and the slider more complicated. Summary of the invention

[0003] The purpose of the present invention is to provide an anti-shaking splicing zipper head assembly, which has the characteristics of not being easy to shake between parts and being easy to assemble.

[0004] The technical solution adopted by the present invention is: an anti-shake splicing zipper head assembly, comprising a slider and a pull tab whose front end is connected to the front end of the slider,

[0005] The assembly also includes a connecting piece and a connecting shaft;

[0006] The middle part of the connecting piece protrudes downward to form a pivoting part, so that the connecting piece has a support part located in front of the pivoting part, and a hook body part located behind the pivoting part, and the middle part of the pivoting part has a pivoting hole, and the hook body part is formed by extending backward from the upper part of the rear side of the pivoting part and then extending downward, so that the lower part of the hook body part forms a accommodating space with an opening facing downward;

[0007] The rear upper surface of the slider is symmetrically provided with a pair of opening and closing edges on the left and right sides, and the middle part of the front upper surface is provided with a connecting edge in a front-to-back direction, the rear part of the connecting edge has a triangle body matching the opening and closing edge, and the front part of the connecting edge is symmetrically provided with a pair of clamping plates, a clamping space in a front-to-back direction is provided between the two clamping plates, and the middle parts of the two clamping plates are provided with a mutually matching through hole;

[0008] The front part of the pull tab is provided with a strip hole which passes through from top to bottom, so that the front end of the pull tab is located in front of the pull hole and has a tensioning rib;

[0009] as well as,

[0010] The pivoting portion of the connecting piece is clamped in the clamping space, and the connecting shaft passes through the pivoting hole and the two through holes so that the middle portion of the connecting piece is pivotally connected to the slider;

[0011] The middle part of the tension rod is clamped between the accommodating space and the upper surface of the triangle, and the rear end of the hook body is clamped in the strip hole.

[0012] The width of the strip-shaped hole in the left-right direction is slightly greater than the thickness of the hook body in the left-right direction.

[0013] A compression spring is arranged between the support portion and the front upper surface of the connecting edge.

[0014] There are at least two connecting pieces arranged side by side.

[0015] The width of the strip-shaped hole in the left-right direction is slightly greater than the sum of the thicknesses of all the hook body parts in the left-right direction.

[0016] Compared with the prior art, the present invention has the advantages that the components are not easy to shake and are easy to assemble. The anti-shake spliced ​​zipper head assembly of the present invention ensures the freedom and flexibility of the pull tab to swing forward and backward by pivoting the pull tab on the slider, making the hook body stuck in the bar hole, the tie rod stuck in the accommodation space below the hook body, and making the width of the bar hole slightly larger than the width of the hook body, and further limits the swing amplitude of the pull tab in the left and right directions, which is relatively stable. Moreover, the components are mainly assembled by snap-fitting, which reduces the difficulty of assembly and is particularly suitable for automated production. BRIEF DESCRIPTION OF THE DRAWINGS

[0030] For the convenience of explanation, in the following embodiments, when the anti-sway splicing zipper head assembly is in use, the movement direction of the zipper head that closes the zipper chain is set to the front, and the movement direction of the zipper head that opens the zipper chain is set to the rear. Therefore, the two sides of the movement direction of the zipper head are the left and the right.

[0031] For example, see Figure 1 and Figure 2 As shown: an anti-shake spliced ​​zipper head assembly includes a slider 10 and a pull tab 20 whose front end is connected to the front end or front part of the slider 10.

[0032] Further speaking:

[0033] The anti-shake splicing zipper head assembly further includes a connecting piece 30 and a connecting shaft 40 .

[0034] Combination Figures 3 to 5 As shown, the connecting piece 30 is usually formed by stamping a metal sheet with a constant thickness. The middle part thereof protrudes downward to form a pivoting portion 32, so that the connecting piece 30 has a support portion 31 located in front of the pivoting portion 32 and a hook body portion 33 located behind the pivoting portion 32. The middle part of the pivoting portion 32 has a pivot hole 321. The hook body portion 33 is formed by the upper part of the rear side edge of the pivoting portion 32 extending backward first and then extending downward, so that the lower part of the hook body portion 33 forms a receiving space S with an opening facing downward, or in other words, the receiving space S is substantially a semicircular shape with an opening at the lower part.

[0035] The rear upper surface of the slider 10 is provided with a pair of opening and closing edges 12 symmetrically on the left and right sides, and a connecting edge 11 is provided in the middle of the front upper surface in a forward and backward direction. The rear of the connecting edge 11 has a triangular body 111 that matches the opening and closing edge 12. Usually, the rear end of the triangular body 111 extends between the two opening and closing edges 12. Looking from top to bottom, a "human"-shaped groove is formed between the outer side surface of the triangular body 111 and the inner side surface of the two opening and closing edges 12. The two chains of the zipper are respectively stuck in a groove, and the opening or closing of the two chains is achieved by pulling the slider 10 forward or backward. At the same time, the front of the connecting edge 11 has a pair of clamping plates 112 symmetrically, and a clamping space W running forward and backward is provided between the two clamping plates 112. The middle parts of the two clamping plates 112 each have a mutually matching through hole 1121. Usually, looking from top to bottom, the clamping space W is a strip-shaped square that opens forward and backward.

[0036] The front part of the pull tab 20 is provided with a strip hole 21 which passes through from top to bottom, so that the front end of the pull tab 20 is located in front of the pull hole 21 and has a tensioning rib 211. Obviously, the strip hole 21 is generally square.

[0037] After assembly:

[0038] The pivoting portion 32 of the connecting piece 30 is clamped in the clamping space W. At this time, the pivoting hole 321 and the through holes 1121 on both sides are aligned, and the connecting shaft 40 passes through the pivoting hole 321 and the two through holes 1121 so that the middle part of the connecting piece 30 is pivoted to the slider 10. At the same time, the middle part of the tie rod 211 is clamped between the accommodating space S and the upper surface of the triangle 111, and the rear end of the hook body 33 is clamped in the strip hole 21. Obviously, after adopting this method, when assembling, the front part of the pull tab 20 can be placed in a suitable position first, and then the connecting piece 30 can be pivoted in place, which greatly reduces the difficulty of assembly.

[0039] It should be noted that the distance between the rear end side of the hook body 33 and the upper surface of the triangle 111 should be limited so that the tie rod 211 will not fall out of the accommodation space S. This is common sense and will not be repeated. In this embodiment, a compression spring 50 is provided between the support portion 31 and the front upper surface of the connecting ridge 11, so that the structure is not only more compact, but also the distance between the rear end side of the hook body 33 and the upper surface of the triangle 111 is better limited.

[0040] Optimized:

[0041] The width of the strip hole 21 in the left-right direction is slightly larger than the thickness of the hook body 33 in the left-right direction. The so-called "slightly larger" in this embodiment means that the width of the strip hole 21 in the left-right direction is as equal to the thickness of the hook body 33 in the left-right direction as possible while ensuring that the pull tab 20 is relatively flexible and can swing back and forth. For example, the width of the strip hole 21 in the left-right direction does not exceed 10% of the thickness of the hook body 33 in the left-right direction. In this way, the pull tab 20 is not easy to swing left and right. For the same reason, the width of the clamping space W in the left-right direction is slightly larger than the width of the connecting piece 30. For example, the width of the clamping space W in the left-right direction does not exceed 10% of the width of the connecting piece 30.

[0042] Further optimization:

[0043] There are at least two connecting pieces 30 arranged side by side (not shown in the figure). At this time, the width of the strip hole 21 in the left-right direction is slightly larger than the sum of the thicknesses of all the hook body parts 33 in the left-right direction, and the width of the clamping space W in the left-right direction is slightly larger than the sum of the widths of all the connecting pieces 30. The concept of "slightly larger than" is the same as described above. In this way, the difficulty of assembly can be further reduced, and the pull tab 20 is less likely to swing left and right, and there is an elastic space between adjacent connecting pieces 30, which further ensures the compactness of the structure and the flexibility of use. Of course, the pivoting parts 32 of all the connecting pieces 30 are stacked side by side and pivoted in the clamping space W, and the hook body parts 33 of all the connecting pieces 30 are stuck in the strip hole 21.

[0044] The above description is only a preferred embodiment of the present invention, and does not limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made by using the contents of the present invention specification and drawings, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
