Description

Technical Field

[0001] The present application relates to the technical field of zipper manufacturing, and particularly relates to a waterproof zipper. Background Art

[0002] A zipper mainly consists of a connecting band, teeth, and a slider. Generally, the connecting band is sewn onto materials such as clothing and tents, and the teeth are continuously and evenly arranged on the connecting band. The slider slides on the teeth to control the opening and closing of the zipper for convenient use. With the development of functionality in industries such as clothing, the demand for corresponding waterproof accessories has been increasing, and certain requirements have been placed on the waterproof performance of zippers.

[0003] However, most of the existing waterproof zippers only achieve waterproofing by covering a waterproof film layer at the connecting band, resulting in the waterproof zipper leaking water through the gaps between each tooth, and the waterproof effect is poor. Utility Model Content

[0004] Based on this, it is necessary to provide a waterproof zipper that can achieve high waterproof performance by improving the teeth and other parts of the zipper.

[0005] To solve the above technical problems, the present application provides the following technical solutions:

[0006] A waterproof zipper, the waterproof zipper at least includes:

[0007] A first connecting band;

[0008] A second connecting band that forms a gap with the first connecting band;

[0009] A plurality of first teeth, and the plurality of first teeth are arranged along the length direction of the first connecting band and connected to the first connecting band; each first tooth includes a first half and a second half, the first half and the second half are disposed on both sides of the first connecting band in the thickness direction, and along the length direction of the first connecting band, the first half and the second half are misaligned and form a first abutting surface;

[0010] A plurality of second teeth, and the plurality of second teeth are arranged along the length direction of the second connecting band and connected to the second connecting band and can mesh with each corresponding first tooth; each second tooth includes a third half and a fourth half, the third half and the fourth half are disposed on both sides of the second connecting band in the thickness direction, and along the length direction of the second connecting band, the third half and the fourth half are misaligned and form a second abutting surface;

[0011] Wherein, the first half body and the third half body are located on the first side of the first connecting band, and the second half body and the fourth half body are located on the second side of the first connecting band; and, along the length direction of the first connecting band, between the adjacent first chain teeth and second chain teeth, the first abutting surface and the second abutting surface are hermetically abutted at the gap.

[0012] It can be understood that this application provides a plurality of first chain teeth and a plurality of second chain teeth. The first half body and the second half body of the first chain teeth are arranged in a staggered manner to form a first abutting surface, and the third half body and the fourth half body of the second chain teeth are arranged in a staggered manner to form a second abutting surface. The first abutting surface and the second abutting surface are hermetically abutted at the gap formed between the first connecting band and the second connecting band, forming a fully enclosed connection between the first chain teeth and the second chain teeth, achieving the waterproof purpose of the waterproof zipper. This setting method seals the structure of the waterproof zipper, so that the gap formed by the staggering of the first half body and the second half body is hermetically blocked by the staggering of the third half body and the fourth half body, realizing the interlacing of the first chain teeth and the second chain teeth, enabling the entire zipper to have high waterproof performance, thereby improving the waterproof performance and sealing performance of the waterproof zipper.

[0013] In one embodiment, the first abutting surface and the second abutting surface are attached to each other in a surface-to-surface manner.

[0014] It can be understood that the surface-to-surface attachment manner between the two abutting surfaces makes there be no gap after the corresponding first chain teeth and second chain teeth are combined, and the attachment is closer, increasing the waterproof performance barrier.

[0015] In one embodiment, the first connecting band is provided with a first convex portion at the edge of the gap, and the end of the second chain tooth facing the first connecting band is provided with a first groove; after the first chain tooth and the second chain tooth are engaged, the first convex portion is hermetically snapped into the first groove.

[0016] It can be understood that the first convex portion of the first connecting band is hermetically snapped into the first groove of the second chain tooth, which can completely seal the connection gap between the first connecting band and the second chain tooth, so that the waterproof zipper has a waterproof function in the structure of the connecting band and the chain teeth, further ensuring the waterproof performance of the waterproof zipper.

[0017] In one embodiment, the second connecting band is provided with a second convex portion at the edge of the gap, and the end of the first chain tooth facing the second connecting band is provided with a second groove; after the first chain tooth and the second chain tooth are engaged, the second convex portion is hermetically snapped into the second groove.

[0018] It is understandable that the second convex part of the second connecting belt is hermetically clamped into the second groove of the first chain tooth, which can completely seal the connecting gap between the second connecting belt and the first chain tooth, so as to further endow the waterproof zipper with waterproof function in the structure of the connecting belt and the chain tooth, and improve the waterproof performance of the waterproof zipper.

[0019] In one embodiment, sealant is provided in the first groove and / or the second groove.

[0020] It is understandable that providing sealant can further ensure the seal between the first groove and the first convex part, or between the second groove and the second convex part, without leaving gaps, thereby increasing the sealed waterproofness of the connection between the connecting belt and the chain tooth.

[0021] In one embodiment, the first connecting belt and the first convex part are integrally formed; and / or, the second connecting belt and the second convex part are integrally formed.

[0022] It is understandable that the integrally formed structure reduces the connection structure between the connecting belt and the convex part, thereby increasing the stability of this structure, ensuring that it is not easy to break and leave gaps between the connecting belt and the convex part, further increasing the waterproof performance of the waterproof zipper, and the integral processing can simplify the production line, thereby reducing its production and processing costs and saving costs.

[0023] In one embodiment, a waterproof film is provided on the surfaces of the first connecting belt and the second connecting belt.

[0024] It is understandable that the waterproof film has strong waterproof performance. Setting this structure on the surfaces of the first connecting belt and the second connecting belt can increase the waterproof performance of the connecting belt and further improve the waterproof ability of the waterproof zipper.

[0025] In one embodiment, the first chain tooth is connected to the first connecting belt by injection molding; the second chain tooth is connected to the second connecting belt by injection molding.

[0026] It is understandable that injection molding can manufacture relatively complex or delicate-shaped parts economically and efficiently. Connecting the first chain tooth and the first connecting belt, and the second chain tooth and the second connecting belt in this way can not only make the shapes of the chain tooth and the connecting belt completely match to ensure the seal at their connection, but also improve the production efficiency of this waterproof zipper and further save production costs.

[0027] In one embodiment, both the first chain tooth and the second chain tooth are made of plastic steel material.

[0028] It is understandable that the plastic-steel material has certain corrosion resistance and is relatively light in weight. When applied to the chain teeth, it can reduce the weight of the first chain teeth and the second chain teeth while increasing their structural strength.

[0029] In one embodiment, along the length direction of the first connecting belt, first engaging grooves are provided on both sides of the first chain teeth, and second engaging grooves are provided on both sides of the second chain teeth. A first engaging portion is provided on the first chain teeth, and a second engaging portion is provided on the second chain teeth.

[0030] The first engaging portion engages with the first engaging groove, and the second engaging portion engages with the second engaging groove.

[0031] It is understandable that the engaging portions and the engaging grooves engage with each other one by one, so that there are no gaps between multiple adjacent first chain teeth and between multiple adjacent second chain teeth, increasing the structural sealing performance and making the waterproof structure of the waterproof zipper more complete.

[0032] Compared with the prior art, the waterproof zipper described herein sets multiple first chain teeth and multiple second chain teeth. The first half body and the second half body of the first chain teeth are arranged in a staggered manner to form a first abutting surface, and the third half body and the fourth half body of the second chain teeth are arranged in a staggered manner to form a second abutting surface. The first abutting surface and the second abutting surface are hermetically abutted at the gap between the first connecting belt and the second connecting belt, forming a fully enclosed connection between the first chain teeth and the second chain teeth to achieve the waterproof purpose of the waterproof zipper. This setting method seals the structure of the waterproof zipper, so that the gap formed by the staggering of the first half body and the second half body is hermetically blocked by the staggering of the third half body and the fourth half body, realizing the interlacing of the first chain teeth and the second chain teeth, making the whole zipper have waterproof performance, and thus improving the waterproof performance and sealing performance of the waterproof zipper.

The term "and / or" used in the specification of this application includes any and all combinations of one or more of the related listed items.

[0047] Please refer to Figures 1 to 3 , this application provides a waterproof zipper 100, which is applied to articles such as clothing, luggage, shoes and hats, and is mainly used as an auxiliary component for slidingly opening or closing the articles. The connecting band and the tooth structure on the zipper are improved to increase its sealing and waterproof performance, so as to enhance the waterproof effect of the waterproof zipper.

[0048] Specifically, as Figures 1 to 6As shown, the waterproof zipper 100 at least includes a first connecting band 10, a second connecting band 20, a plurality of first teeth 30, and a plurality of second teeth 40. A gap 22 is formed between the second connecting band 20 and the first connecting band 10. Each first tooth 30 is arranged along the length direction y of the first connecting band 10 and connected to the first connecting band 10. Each first tooth 30 includes a first half 31 and a second half 32. The first half 31 and the second half 32 are disposed on both sides of the first connecting band 10 in the thickness direction z, and along the length direction y of the first connecting band 10, the first half 31 and the second half 32 are offset and form a first abutting surface 33. The plurality of second teeth 40 are arranged along the length direction y of the second connecting band 20 and connected to the second connecting band 20, and can mesh with each corresponding first tooth 30. Each second tooth 40 includes a third half 41 and a fourth half 42. The third half 41 and the fourth half 42 are disposed on both sides of the second connecting band 20 in the thickness direction z, and along the length direction y of the second connecting band 20, the third half 41 and the fourth half 42 are offset and form a second abutting surface 43. Among them, the first half 31 and the third half 41 are located on the first side of the first connecting band 10, and the second half 32 and the fourth half 42 are located on the second side of the first connecting band 10. And along the length direction y of the first connecting band 10, between adjacent first teeth 30 and second teeth 40, the first abutting surface 33 and the second abutting surface 43 are hermetically abutted at the gap 22.

[0049] It should be noted that in the prior art, the waterproof zipper 100 generally only covers a waterproof film layer at its connecting band to achieve the waterproof effect. However, gaps are generated when the teeth are engaged with the connecting band and when the teeth on both sides of the waterproof zipper 100 are engaged, causing the waterproof zipper 100 to leak water from its structural gaps, resulting in a poor waterproof effect. In this application, both the first teeth 30 and the second teeth 40 are divided into two halves. Among them, the first half 31 and the second half 32 of the first tooth 30 are offset and form a first abutting surface 33, and the third half 41 and the fourth half 42 of the second tooth 40 are offset and form a second abutting surface 43. The first abutting surface 33 and the second abutting surface 43 are hermetically abutted at the gap 22 formed between the first connecting band 10 and the second connecting band 20 to achieve the fully enclosed connection between the first tooth 30 and the second tooth 40, and achieve the waterproof purpose of the waterproof zipper 100. This setting method seals the structure of the waterproof zipper 100, so that the abutting surface formed by the offset of the first half 31 and the second half 32 is hermetically blocked by the abutting surface formed by the offset of the third half and the fourth half, thereby improving the waterproofness and sealing performance of the waterproof zipper 100 to obtain a waterproof zipper 100 with high waterproof performance.

[0050] Exemplarily, a waterproof film (not shown in the figure) is provided on the surfaces of the first connecting strip 10 and the second connecting strip 20 to increase the waterproof performance of the connecting strip through the waterproof film, thereby further enhancing the waterproof effect of the waterproof zipper 100. The waterproof film can be made of materials with waterproof effects such as neoprene, butyl rubber, and ethylene propylene diene monomer rubber. Of course, the waterproof film material is not limited to this, and the actual material composition can be determined according to specific usage situations.

[0051] Preferably, as Figure 1 and Figure 2 shown, a first convex portion 11 is provided at the edge of the first connecting strip 10 at the gap 22. After the first chain tooth 30 and the second chain tooth 40 are engaged, the first convex portion 11 can be hermetically clamped with the second chain tooth 40.

[0052] Here, the first convex portion 11 can be set in shapes such as spherical or triangular that can be adapted to be clamped with the second chain tooth 40 to seal the gap 22. In this embodiment, the first convex portion 11 is set as spherical. Of course, the shape presented by the first convex portion 11 is not limited to this, and it can be specifically determined according to actual usage requirements and usage scenarios.

[0053] In one embodiment, the first connecting strip 10 and the first convex portion 11 can be provided integrally. The integral processing and forming not only reduce the connection structure of the waterproof zipper 100, thereby making its structure more stable, but also the integral processing of the waterproof zipper 100 can simplify the production line, thereby reducing its production and processing costs and saving costs.

[0054] Furthermore, a second convex portion 21 is provided at the edge of the second connecting strip 20 at the gap 22. After the first chain tooth 30 and the second chain tooth 40 are engaged, the second convex portion 21 can be hermetically clamped with the first chain tooth 30.

[0055] Here, the second convex portion 21 can also be set in shapes such as spherical or triangular that can be adapted to be clamped with the first chain tooth 30 to seal the gap 22. In this embodiment, the second convex portion 21 is set as spherical. Of course, the shape presented by the second convex portion 21 is not limited to this, and it can be specifically determined according to actual usage requirements and usage scenarios.

[0056] In one embodiment, the second connecting strip 20 and the second convex portion 21 can be provided integrally. The integral structure setting reduces the connection structure between the connecting strip and the convex portion, thereby increasing the stability of this structure, ensuring that the connection between the connecting strip and the convex portion is not easily broken to leave a gap, further increasing the waterproof performance of the waterproof zipper 100, and the integral setting can save the production cost of this structure, further reducing the production cost of the waterproof zipper.

[0057] As Figures 4 to 6As shown, preferably, the first chain tooth 30 is made of plastic-steel material and is connected to the first connecting belt 10 by injection molding. Here, the plastic-steel material has certain corrosion resistance and is light in weight, so that while the weight of the first chain tooth 30 is reduced, its structural strength is increased; and the connection by injection molding also makes the shape of the first chain tooth 30 perfectly adapted to the first connecting belt 10, ensuring the tightness at the connection between the two, and this method can improve production efficiency and save costs such as labor costs. Of course, this is not limited, and the material of the first chain tooth 30 can also be selected according to actual situations.

[0058] Exemplarily, the first abutting surface 33 and the second abutting surface 43 are attached to each other in a surface-to-surface manner, so that there is no gap after the corresponding first chain tooth 30 and second chain tooth 40 are connected, so that the waterproof zipper 100 has a waterproof function in terms of structure, increasing its waterproof barrier.

[0059] Further, one end of the first chain tooth 30 facing the second connecting belt 20 is provided with a second groove 34; after the first chain tooth 30 and the second chain tooth 40 are engaged, the second convex portion 21 is hermetically snapped into the second groove 34. In this way, the connection gap between the second connecting belt 20 and the first chain tooth 30 is completely sealed, so that the waterproof zipper 100 has a waterproof function in terms of the structure of the connecting belt and the chain teeth, so as to improve the waterproof performance of the waterproof zipper 100.

[0060] Here, sealant can be provided in the second groove 34 to ensure that there is no gap between the second groove 34 and the second convex portion 21, further increasing the sealed waterproof performance of the connection between the connecting belt and the chain teeth.

[0061] In an embodiment, along the length direction y of the first connecting belt 10, first engaging grooves 35 are provided on both sides of the first chain tooth 30, and a first engaging portion 36 is provided on the first chain tooth 30, and the first engaging portion 36 is engaged with the first engaging grooves 35 to realize the sealed connection between multiple adjacent first chain teeth 30.

[0062] Please continue to refer to Figures 4 to 6 , the second chain tooth 40 is connected to the second connecting belt 20 by injection molding. The injection molding method can manufacture relatively complex or delicate-shaped parts and is economical and efficient. This method ensures the tightness at the connection between the second chain tooth 40 and the second connecting belt 20 and improves the production efficiency of the waterproof zipper, saving production costs.

[0063] Preferably, the second chain tooth 40 is made of plastic-steel material to enhance its structural strength and reduce its weight for convenient use.

[0064] Furthermore, a first groove 44 is formed at one end of the second chain tooth 40 facing the first connecting belt 10; after the second chain tooth 40 and the first chain tooth 30 are engaged, the first convex portion 11 can be hermetically snapped into the first groove 44, so as to further completely seal the connection gap between the first connecting belt 10 and the second chain tooth 40, enabling the waterproof zipper 100 to have high waterproof performance in terms of the structure of the connecting belt and the chain teeth.

[0065] Here, a sealant is provided in the first groove 44, thus further enhancing the sealed waterproof performance of the connection between the first connecting belt 10 and the second chain tooth 40.

[0066] Furthermore, second engaging grooves 45 are provided on both sides of the second chain tooth 40, and a second engaging portion 46 is also provided on the second chain tooth 40. The second engaging grooves 45 and the second engaging portion 46 are engaged to achieve the sealed connection between multiple adjacent second chain teeth 40, enhancing the sealing performance of the single-sided chain tooth structure on the waterproof zipper 100.

[0067] The technical features of the above-described embodiments can be combined arbitrarily. For the sake of brevity of description, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered as the scope described in this specification.

[0068] The above-described embodiments merely represent several implementation manners of the present application. The description is relatively specific and detailed, but it should not be construed as a limitation to the scope of the patent application. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present application, several modifications and improvements can still be made, and these all belong to the protection scope of the present application. Therefore, the patent protection scope of the present application shall be subject to the appended claims.
