Description

Technical Field

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

[0002] A zipper is a fastener that uses a series of linked elements to connect or separate items. It is widely used on items such as clothing, bags, and tents. Generally, a zipper consists of a slider and a pull tab connected to the front end of the slider. The rear of the slider features two opening and closing ridges arranged in a herringbone pattern, and a connecting ridge running forward and backward in the middle of the front upper surface. The rear of the connecting ridge features a triangular body that matches the opening and closing ridges. During use, the two elements engage in two guide grooves formed by the opening and closing ridges and the triangular body. As the slider moves back and forth, the two elements lock together or separate. The front end of the pull tab is connected to the front end of the slider, making it easy for the user to grasp and pull the slider forward and backward. A common drawback is that the connection between the pull tab and the slider is loose, making it easy for the slider to move, especially side-to-side. In some cases, the slider can become stuck, making it inconvenient. To address this issue, many industry experts have made numerous improvements to the connection between the pull tab and the slider, but these improvements often result in complex assembly of the two. Summary of the Invention

[0003] The purpose of the present invention is to provide an anti-shaking splicing zipper slider assembly, which has the characteristics of not being easy to shake between components 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 connected to the front end of the slider,

[0005] The assembly further comprises a connecting piece and a connecting shaft;

[0006] The middle portion of the connecting piece protrudes downward to form a pivot portion, so that the connecting piece has a support portion located in front of the pivot portion and a hook portion located behind the pivot portion, and the middle portion of the pivot portion has a pivot hole. The hook portion is formed by extending backward and then downward from the upper portion of the rear side of the pivot portion, so that the lower portion of the hook portion 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 part of the two clamping plates has a mutually matching through hole.

[0008] The front portion of the pull tab is provided with a strip hole running through it 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 pivotal portion of the connecting piece is clamped in the clamping space, and the connecting shaft passes through the pivot hole and the two through holes so that the middle portion of the connecting piece is pivotally connected to the slider;

[0011] The middle portion of the tension rod is clamped between the accommodating space and the upper surface of the triangle, and the rear end portion 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 provided 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 larger than the sum of the thicknesses of all the hook bodies in the left-right direction.

[0016] Compared to existing technologies, the present invention offers advantages in that the components are less susceptible to shaking and are easier to assemble. By pivotally connecting the pull tab to the slider, securing the hook body within a strip-shaped hole and the traction bar within the accommodation space below the hook body, and making the width of the strip-shaped hole slightly larger than the width of the hook body, the present invention ensures the pull tab's free and flexible forward and backward swing, further limiting the pull tab's left-right shaking, resulting in greater stability. Furthermore, the components are primarily assembled through a snap-fit ​​connection, reducing assembly complexity and making it particularly suitable for automated production.

[0030] For ease of explanation, in the following embodiments, when the anti-sway spliced ​​zipper slider assembly is in use, the zipper slider's movement direction for closing the zipper chain is set forward, and the zipper slider's movement direction for opening the zipper chain is set backward. Therefore, the two sides of the zipper slider's movement direction are left and right.

[0031] For example, see Figure 1 and Figure 2 As shown: an anti-shake splicing zipper head assembly, including 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 slider assembly further includes a connecting piece 30 and a connecting shaft 40 .

[0034] Combine Figures 3 to 5 As shown, the connecting piece 30 is typically formed by stamping a metal sheet of constant thickness. A pivot portion 32 protrudes downward from the center of the connecting piece 30, thereby forming a support portion 31 in front of the pivot portion 32 and a hook portion 33 behind the pivot portion 32. A pivot hole 321 is defined in the center of the pivot portion 32. The hook portion 33 is formed by extending backward and then downward from the upper portion of the rear side of the pivot portion 32, thereby forming a downwardly open accommodation space S at the bottom of the hook portion 33. In other words, the accommodation space S is essentially a semicircular shape with an open bottom.

[0035] The rear upper surface of the slider 10 is symmetrically provided with a pair of opening and closing ridges 12 on either side. A connecting ridge 11 is provided in the middle of the front upper surface, running forward and backward. The rear portion of the connecting ridge 11 has a triangular body 111 that matches the opening and closing ridges 12. Typically, the rear end of the triangular body 111 extends between the two opening and closing ridges 12. When viewed from above, a herringbone-shaped groove is formed between the outer side of the triangular body 111 and the inner side of the two opening and closing ridges 12. The two chains of the zipper are respectively retained in one groove, and the two chains are opened or closed by pulling the slider 10 forward or backward. Furthermore, the front portion of the connecting ridge 11 has a pair of symmetrical clamping plates 112. A clamping space W running forward and backward is defined between the two clamping plates 112, and each clamping plate 112 has a mutually matching through-hole 1121 in the middle. Typically, when viewed from above, the clamping space W is a square strip that opens forward and backward.

[0036] The front portion of the pull tab 20 is provided with a strip hole 21 that passes through the pull tab 20 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 traction rib 211. Obviously, the strip hole 21 is generally square.

[0037] After assembly is in place:

[0038] The pivoting portion 32 of the connecting piece 30 is clamped within the clamping space W. At this point, the pivoting hole 321 and the through-holes 1121 on either side are aligned. The connecting shaft 40 passes through the pivoting hole 321 and the two through-holes 1121, thereby pivotally connecting the central portion of the connecting piece 30 to the slider 10. Simultaneously, the central portion of the tie rod 211 is clamped between the accommodating space S and the upper surface of the triangular body 111, and the rear end of the hook portion 33 is clamped within the strip-shaped hole 21. Obviously, with this approach, during assembly, the front portion of the pull tab 20 can be placed in the appropriate position first, and then the connecting piece 30 can be pivoted into place, greatly reducing the difficulty of assembly.

[0039] It should be noted that the distance between the rear end side of the hook portion 33 and the upper surface of the triangular body 111 should be limited to prevent the tie rod 211 from falling out of the accommodation space S. This is common sense and will not be elaborated on. In this embodiment, a compression spring 50 is further provided between the support portion 31 and the front upper surface of the connecting rib 11, thereby not only making the structure more compact but also effectively limiting the distance between the rear end side of the hook portion 33 and the upper surface of the triangular body 111.

[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. In this embodiment, the so-called "slightly larger" means that the width of the strip hole 21 in the left-right direction is as equal as possible to the thickness of the hook body 33 in the left-right direction 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] At least two connecting pieces 30 are arranged side by side (not shown). The width of the strip-shaped hole 21 in the left-right direction is slightly greater than the sum of the thicknesses of all the hook portions 33 in the left-right direction, and the width of the clamping space W in the left-right direction is slightly greater than the sum of the widths of all the connecting pieces 30. The concept of "slightly greater than" is the same as described above. This further reduces assembly difficulty and makes the pull tab 20 less likely to swing left or right. The elastic space between adjacent connecting pieces 30 further ensures a compact structure and flexible use. Of course, the pivotal portions 32 of all the connecting pieces 30 are stacked side by side and pivotally connected within the clamping space W, and the hook portions 33 of all the connecting pieces 30 are locked within the strip-shaped hole 21.

Any equivalent structure or equivalent process transformation made by using the contents of the present invention description and drawings, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
