Description

Technical Field

[0001] This utility model relates to zipper structures, and more specifically, to a zipper with a detachable pull tab. Background Technology

[0002] Zippers are a common component in daily life. A zipper consists of teeth, a slider, and top and bottom stops (front and back stops) or locking mechanisms. The teeth are the key component, directly determining the zipper's lateral pulling strength. Generally, a zipper has two straps, each with a row of teeth, arranged alternately. The slider grips the teeth on both sides, and by sliding along the loop, the teeth can be engaged or disengaged. The slider typically includes a slider tab and a slider body. The slider body has two inlets and one outlet. The slider body includes an upper plate and a lower plate. The upper plate has a nose for connecting the slider tab and is connected to the lower plate by a support core.

[0003] Existing zipper pulls all have a perforation at one end to allow the zipper nose to pass through. One end of the zipper nose is fixed to the upper plate, and the other end is close to the top surface of the upper plate to prevent the zipper pull from coming out. The zipper pulls are generally thin and are used frequently, so the damage rate of the zipper pulls on the zipper pull head is relatively high. And the existing zipper nose structure makes it inconvenient to replace the zipper pulls.

[0004] Therefore, a new solution is needed to address this problem. Utility Model Content

[0005] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a zipper with a detachable pull tab.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a zipper with a detachable pull tab, including a pull tab, a zipper head body and a zipper nose, one end of the pull tab is provided with a through hole for accommodating the zipper nose to pass through, the zipper nose includes a fixing part fixed to the zipper head body and a rotating part arranged in an L shape, one end of the rotating part and the fixing part are rotatably connected to form a gap for accommodating the pull tab to detach from the zipper nose.

[0007] The present invention is further configured such that: the top surface of the pull head body is provided with two positioning protrusions that respectively abut against the left and right sides of the rotating part; the rotating part rotates and disengages from the two positioning protrusions by deforming the positioning protrusions.

[0008] The present invention is further configured such that the top surface of the positioning protrusion is provided with an arc surface.

[0009] The present invention is further configured such that: the end face of the rotating part is provided with a rotating shaft, the fixed part is provided with a rotating hole for accommodating the rotating shaft to pass through, and the end of the rotating shaft facing away from the rotating part is provided with a limiting member that abuts against the fixed part and is used to restrict the rotating shaft from disengaging from the rotating hole.

[0010] The present invention is further configured such that: the limiting member includes a plurality of metal sheets, one end of the metal sheet is fixed to the rotating shaft, and the metal sheet is bent and deformed away from the rotating shaft and abuts against the fixed part.

[0011] The present invention is further configured such that: a groove is provided inward on the side of the fixing part facing away from the rotating part, the inner wall of the groove is connected to the rotating hole, and the limiting member is located in the groove.

[0012] The present invention is further configured such that: an elastic gasket is provided between the rotating part and the fixed part and is compressed by both.

[0013] The present invention is further configured such that the pull tab, the pull head body, and the pull nose are all made of stainless steel.

[0014] In summary, this utility model has the following beneficial effects: When the pull tab is damaged, by rotating the rotating part, one end of the rotating part rotates away from the pull head body, forming a gap between the end of the rotating part and the pull head body to accommodate the pull tab coming out. This allows the rotating part to disengage from the perforation, separating the pull tab from the pull head body, and then a new pull tab can be inserted. In the case of a damaged or lost pull tab, a new pull tab can be directly inserted. Finally, by rotating the rotating part, one end of the rotating part rotates towards the pull head body. By reducing the distance between the end of the rotating part and the pull head body, the pull tab is prevented from detaching from the pull nose, thus completing the fixation of the new pull tab, making pull tab replacement simple and convenient.

[0020] The present invention will now be described in detail with reference to the accompanying drawings and embodiments. Example

[0021] A zipper with a detachable pull tab, such as Figure 1, Figure 3 and Figure 4 As shown, the zipper includes a stainless steel pull tab 1, a zipper head body 2, and a zipper nose. Stainless steel is corrosion-resistant, which improves the lifespan of the zipper head. One end of the pull tab 1 has a through-hole for the zipper nose to pass through; the through-hole has a rectangular cross-section. The zipper nose includes a fixing part 3 welded to the zipper head body 2 and an L-shaped rotating part 4. The fixing part 3 is also L-shaped. One end of the rotating part 4 is rotatably connected to the fixing part 3 to form a gap for the pull tab 1 to detach from the zipper nose. When the pull tab 1 is damaged, rotating the rotating part 4 allows it to detach from the zipper nose. A gap is formed between the end of the rotating part 4 and the zipper head 2 to accommodate the pull tab 1 to come out, so that the rotating part 4 can disengage from the perforation, realizing the separation of the pull tab 1 and the zipper head 2. Then, a new pull tab 1 can be inserted. If the pull tab 1 is damaged or lost, a new pull tab 1 can be directly inserted. Finally, the rotating part 4 is rotated so that one end of the rotating part 4 is close to the zipper head 2. By reducing the distance between the end of the rotating part 4 and the zipper head 2, the pull tab 1 is restricted from detaching from the zipper nose, thus completing the fixation of the new pull tab 1, making the replacement of the pull tab 1 simple and convenient.

[0022] Specifically, such as Figure 1 , Figure 3 and Figure 4 As shown, the top surface of the slider body 2 is integrally formed with two positioning protrusions 5 that respectively abut against the left and right sides of the rotating part 4. The rotating part 4 rotates and disengages from the two positioning protrusions 5 by deforming the positioning protrusions 5. Since both the slider body 2 and the positioning protrusions 5 are made of stainless steel, they are elastic and can deform and recover. When force is applied to rotate the rotating part 4, the side of the rotating part 4 abuts against the positioning protrusions 5. When a large force is applied, the slider body 2 and the positioning protrusions 5 can be slightly deformed, thereby rotating the rotating part 4 out of the space between the two positioning protrusions 5, which facilitates the installation or removal of the slider 1. The top surface of the slider body 2 A recess is provided between the two positioning protrusions 5 to prevent the pull head 2 from interfering with the rotating part 4, making the rotation of the rotating part 4 smoother. The reset process of the rotating part 4 is the same as the above process. The deformation of the positioning protrusions 5 makes the rotating part 4 rotate between the two positioning protrusions 5. The rotation of the rotating part 4 can be restricted by the two positioning protrusions 5, keeping the pull tab 1 and the pull nose in a connected state. Furthermore, the top surface of the positioning protrusions 5 is provided with an arc surface 6, which can play a guiding role, making it easier for the rotating part 4 to rotate out between the two positioning protrusions 5, and facilitating the disassembly and assembly of the pull tab 1.

[0023] like Figure 1 , Figure 2 and Figure 3As shown, the end face of the rotating part 4 is provided with a rotating shaft 7. The rotating part 4 and the fixed part 3 rotate relative to each other about the axis of the rotating shaft. The fixed part 3 is provided with a circular rotating hole 8 for accommodating the rotating shaft 7. The end of the rotating shaft 7 facing away from the rotating part 4 is provided with a limiting member that abuts against the fixed part 3 and is used to prevent the rotating shaft 7 from disengaging from the rotating hole 8. When the rotating part 4 and the fixed part 3 rotate relative to each other, the rotating shaft 7 rotates within the rotating hole 8. The limiting member can prevent the rotating shaft 7 from disengaging from the rotating hole 8, thereby keeping the rotating part 4 and the fixed part 3 in a connected state. Specifically, the limiting member includes several metal pieces 9. One end of the metal piece 9 is integrally formed with the rotating shaft 7. The rotating shaft 7 is tubular. After the end face of the rotating shaft 7 is cut to form several notches, metal sheets 9 can be formed between adjacent notches. After the rotating shaft 7 and several metal sheets 9 are passed through the rotating hole 8, the metal sheets 9 bend and deform away from the rotating shaft 7 and abut against the fixing part 3. Thus, the rotating shaft 7 can be restricted from coming out by the metal sheets 9. The production and assembly are relatively simple and convenient. The fixing part 3 has a groove 10 inward on the side away from the rotating part 4. The inner wall of the groove 10 is connected to the rotating hole 8. The limiting member is located in the groove 10. The groove 10 can accommodate the limiting member and the end of the rotating shaft 7, thus protecting the limiting member and the rotating shaft 7, and thus preventing the rotating part 4 and the fixing part 3 from separating.

[0024] like Figure 1 , Figure 2 and Figure 3 As shown, a flexible gasket 11 is provided between the rotating part 4 and the fixed part 3 and is squeezed by both. Specifically, the gasket 11 is made of plastic. A circular hole is opened in the center of the gasket 11 to accommodate the rotating shaft 7. The end faces of the gasket 11 and the rotating part 4 are bonded and fixed. When the rotating part 4 and the fixed part 3 are assembled, the gasket 11 is clamped by both and can produce slight deformation. This can prevent the assembly gap between the rotating part 4 and the fixed part 3 from occurring, which would cause the rotating part 4 to loosen.

All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
