Description

Technical Field

[0001] The utility model relates to the field of zippers, in particular to a detachable zipper head. Background Art

[0002] Zippers are ubiquitous in our daily lives. Zippers are connectors that connect or separate items by opening and closing two continuous, but offset, chain teeth. They are widely used in clothing, bags, tents, shoes, and more.

[0003] The zipper's teeth open and close via the zipper pull, which is susceptible to damage after repeated and prolonged use. If the main product, such as clothing or luggage, is still in good condition and only the zipper pull is damaged, replacing the pull without discarding the main product is a cost-effective solution. However, replacing a zipper pull requires specialized tools such as a professional sewing machine, and often requires removing stitches for installation. This is not only inconvenient, but the new stitching can also degrade the original appearance.

[0004] In addition, existing detachable zipper pull products have one or more disadvantages, such as waste of materials, loose connection between the upper and lower plates, or the product cannot be used to encrypt anti-theft bags. Utility Model Content

[0005] In order to overcome the problems existing in the above-mentioned background technology, the utility model provides a detachable zipper pull.

[0006] The utility model adopts the following technical solutions:

[0007] A detachable zipper head comprises a pull tab and a slider, wherein the slider comprises a pull nose, a top plate, a bottom plate, and a chain splitter wedge connecting the top plate and the bottom plate; the chain splitter wedge is formed by tightly fitting a chain splitter column and a chain splitter cylinder, both of which have wedge-shaped cross sections and are tightly fitted to each other.

[0008] Preferably, the chain splitting column and the top plate are integrally formed, and the chain splitting cylinder and the bottom plate are integrally formed.

[0009] Preferably, after the chain splitting column and the chain splitting cylinder are sleeved, screws are passed through the non-threaded holes on the base plate and the threaded holes on the chain splitting column to further fix them.

[0010] Chain closing wings are provided on at least one of the top plate and the bottom plate, at an end away from the chain splitting wedge and on both sides of the interior of the slider.

[0011] In summary, the present utility model includes at least one of the following beneficial technical effects: 1. When the zipper head is damaged during use, if the damaged zipper head is a traditional zipper head, it can be directly damaged and removed. If the damaged zipper head is the zipper head of the present utility model, it can be removed by unscrewing the fixing screw. After removal, it can be easily replaced with the zipper head of the present utility model without the need for professional personnel and professional tools. 2. In terms of appearance, except for adding a screw in an inconspicuous place, the rest of the present utility model can be made to be exactly the same as the traditional zipper head. When the screw is placed on one side of the bottom plate or the split chain wedge is fixed with glue instead, on the one hand, it can make the appearance more imperceptible to users, and on the other hand, because it is not easy to disassemble, it can also be used in password suitcases and the like. 3. The types and amounts of production materials are equivalent to those of traditional zipper heads, without increasing material costs. 4. The structure of the split chain wedge can prevent the longitudinal and transverse deformation of the zipper head that may occur during use to the greatest extent, and it is not easy to damage the zipper head.

[0017] The following describes the specific embodiments of the present utility model with reference to the drawings.

[0018] As Figures 1 to 4 shown, a detachable zipper head includes a pull tab 1 and a zipper head 2. The zipper head 2 includes a pull nose 21, a top plate 22, a bottom plate 23, and a split chain wedge 3 connecting the top plate 22 and the bottom plate 23.

[0019] On at least one of the top plate 22 and the bottom plate 23, and at one end away from the split chain wedge 3, on both sides inside the zipper head 2, chain closing wings 222 are provided.

[0020] So far, the present utility model is almost indistinguishable from the traditional zipper head in terms of appearance and function.

[0021] The special feature of the present utility model lies in that the split chain wedge 3 is not integrally formed with the top and bottom plates like a traditional zipper head. Instead, it is formed by tightly sleeving two parts, namely a split chain column 221 and a split chain cylinder 231, which have the same wedge-shaped cross-section and are tightly fitted to each other, and then reinforced with screws 4. Among them, the split chain column 221 is integrally formed with the top plate 22, and the split chain cylinder 231 is integrally formed with the bottom plate 23.

[0022] In this way, it can not only prevent the relative up and down deformation of the top plate 22 and the bottom plate 23 during use, but also prevent the rotational misalignment of the top and bottom plates with the split chain wedge 3 as the axis, thus achieving a firm effect similar to that of a traditional zipper head. However, when the fixing screw 4 is removed, the top plate 22 and the bottom plate 23 can be easily separated, ultimately achieving the effect that ordinary people can easily replace the broken zipper heads on clothes, luggage, etc. without professional personnel and professional tools.

[0023] The above is only the specific implementation manner of the present utility model, but the design concept of the present utility model is not limited thereto. Any non-substantive modification made to the present utility model using this concept shall fall within the scope of infringement of the protection scope of the present utility model.
