Description

Technical Field

[0001] The present application relates to the technical field of clothing sewing, and in particular to a chain link belt, a zipper, clothing, packaging and a tent. Background Art

[0002] A zipper is a connector that uses continuously arranged chain teeth to connect or separate items. It is widely used in clothing, bags, and tents. A zipper consists of a pair of toothed chain belts and a slider. The slider slides along the direction of the zipper tape to achieve the zipper's opening and closing functions.

[0003] The waterproof zipper in the prior art is designed to use an elastomeric resin to surround the tape, and then make a hole at the edge of the tape to implant the teeth. Although this method can achieve waterproof function and improve the horizontal pulling strength of the teeth to a certain extent, it will encounter some technical difficulties during implementation. For example, the size of the hole must be strictly controlled. If the hole diameter is too large, it may lead to the weakening of the tape structure; if the hole diameter is too small, it may affect the injection molding of the teeth, causing air holes or incomplete filling, which will directly affect the bite strength and overall durability of the zipper. In addition, in actual use, due to the horizontal pulling force, gaps may be generated at the holes of the zipper due to uneven force, which will not only affect the waterproof performance of the zipper, but also may cause premature damage to the zipper. In particular, when it is repeatedly used and subjected to large tension, the tape material at the edge of the hole may be deformed or broken, further reducing the reliability and service life of the zipper. Utility Model Content

[0004] The purpose of the present application is to provide a zipper belt, which can enhance the waterproof performance of the zipper and improve the horizontal pulling strength of the teeth by providing a cloth belt assembly with a waterproof layer covering the core layer, and providing a protruding structure in the implant area of ​​the cloth belt assembly and making the teeth fit therein, thereby avoiding the weakening of the cloth belt material caused by hole extraction and implantation and the gap problem that may occur during use, thereby improving the overall durability and reliability of the zipper. Another purpose of the present application is to provide a zipper, clothing, packaging and tent.

[0005] To achieve the above-mentioned purpose, the present application provides a chain tooth belt, comprising:

[0006] A cloth belt assembly, comprising a belt core layer and a waterproof layer completely covering the outside of the belt core layer, wherein the edge of the cloth belt assembly has a dental implant area with a raised structure;

[0007] A tooth assembly is arranged on the cloth belt assembly, and the tooth assembly includes teeth arranged along the implant area, and the interior of the teeth is embedded with the protruding structure.

[0008] In some embodiments, the dental implant area includes a first area located on the front side of the tape assembly and a second area located on the back side of the tape assembly;

[0009] The first region or the second region is provided with the protruding structure, and a single surface inside the tooth is engaged with the protruding structure; or,

[0010] The protruding structures are provided in both the first area and the second area, and the two surfaces inside the teeth are engaged with the protruding structures at corresponding positions.

[0011] In some embodiments, the cross-sectional shape of the protrusion structure is circular; or,

[0012] The cross-section of the protrusion structure is a square.

[0013] In some embodiments, the tooth comprises a head and a pair of roots connected to the head, the pair of roots are distributed on the front and back sides of the cloth belt assembly, and the roots are provided with a recessed structure engaged with the raised structure;

[0014] The thickness of the protruding structure is greater than 10% and not greater than 50% of the thickness of the root; and / or,

[0015] The recessed structure is located in the engagement structure where the root portion is combined with the tape assembly, and the area of ​​the end surface of the raised structure accounts for less than 50% of the area of ​​the engagement structure; and / or,

[0016] A set angle is formed between the height side surface of the protruding structure and the cloth belt assembly, and the set angle is within a closed interval of 95° to 100°.

[0017] In some embodiments, the protruding structure is formed on the implant area by die casting.

[0018] In some embodiments, the material of the core layer is resin; and / or,

[0019] The waterproof layer is made of transparent resin.

[0020] The present application also provides a zipper, comprising the above-mentioned chain element tape.

[0021] The present application also provides a garment comprising the above-mentioned zipper.

[0022] The present application also provides a package, comprising the above-mentioned zipper.

[0023] The present application also provides a tent, comprising the above-mentioned zipper.

[0024] Compared with the above-mentioned background technology, the chain tooth belt provided in the present application mainly includes a cloth belt assembly and a tooth assembly. The cloth belt assembly is provided with a belt core layer and a waterproof layer completely covering the outside of the belt core layer, and the edge of the cloth belt assembly has an implant area with a raised structure; the tooth assembly is arranged on the cloth belt assembly, and the tooth assembly includes teeth arranged along the implant area, and the interior of the teeth is interlocked with the raised structure.

[0025] In the prior art, the implementation of waterproof zippers mainly relies on making holes on the edge of the tape and then implanting teeth, and enhancing the waterproof performance by coating with elastomeric resin. However, this method has some obvious defects, such as the problem of strict control of the hole size, the gap that may be generated at the hole, and the possible weakening of the tape material. These problems not only affect the waterproof performance of the zipper, but also reduce its overall durability and reliability. In response to these technical problems, the chain tooth belt technical solution provided by the present application has been innovatively improved. First, by providing a waterproof layer that completely covers the core layer of the tape assembly on the tape assembly, the waterproof performance of the zipper is fundamentally enhanced. Secondly, a raised structure is provided in the implantation area on the edge of the tape assembly, and these raised structures are interlocked with the inside of the teeth to form a mechanical combination. This combination method not only improves the flat pulling strength of the teeth, but also avoids the weakening of the tape material that may be caused by making holes because there is no need to make holes on the tape. In addition, due to the engagement of the raised structure with the teeth, the gap problem that may be caused by hole extraction and implantation is eliminated, which further improves the reliability of the zipper when it is repeatedly used and subjected to large pulling forces.

[0026] In combination with the above structure and process description, it can be seen that the link tooth belt has at least the following beneficial effects: the link tooth belt achieves enhanced waterproof performance of the zipper and improved flat pulling strength of the teeth by providing a cloth belt assembly with a waterproof layer covering the core layer, and providing a protruding structure in the implantation area of ​​the cloth belt assembly and allowing the inside of the teeth to engage with it, thereby avoiding the weakening of the cloth belt material due to hole extraction and implantation and the gap problem that may occur during use, thereby improving the overall durability and reliability of the zipper.

[0036] Tooth component 2, tooth 21, head 211, root 212, recessed structure 2121, and occlusal structure 2122. DETAILED DESCRIPTION

[0037] The horizontal pulling strength of the teeth refers to the maximum pulling force that the zipper teeth can withstand in the horizontal direction, which is an important indicator to measure the strength of the zipper.

[0038] However, clothing related to outdoor activities mostly uses waterproof zippers, including nylon reverse waterproof, plastic steel and metal waterproof zippers, but most of them are splash-proof. As customers increase their outdoor activities, the requirements for zipper waterproof function will become higher and higher. Waterproof zippers are used in rainproof, rainstorm-proof and water sports equipment. In addition to meeting the waterproof function, they also have high requirements for tooth flat pull.

[0039] In view of the defects of the existing waterproof zipper in the aforementioned background technology, the purpose of the present application is to provide a chain tooth belt, by providing a cloth belt assembly 1 with a waterproof layer 12 covering a core layer 11, providing a protruding structure 13 in the implantation area 101 of the cloth belt assembly 1, and making the inside of the tooth 21 in the tooth assembly 2 fit with the protruding structure 13. Such a structural design enables the tooth 21 to form an integral body with the protruding structure 13 on the cloth belt assembly 1, thereby enhancing the stability of the tooth 21 on the cloth belt assembly 1, improving the flat pulling strength of the tooth 21, and significantly enhancing the waterproof function of the zipper.

[0040] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0041] In order to enable those skilled in the art to better understand the present application, the present application is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0042] Please refer to Figures 1 to 3 ,in, Figure 1 A schematic diagram of a chain link belt provided in an embodiment of the present application, Figure 2 A schematic diagram of a tooth and cloth belt assembly provided in an embodiment of the present application, Figure 3 A schematic diagram of a cloth belt assembly provided in an embodiment of the present application.

[0043] In the first specific embodiment, the link belt provided by the embodiment of the present application mainly includes a cloth belt assembly 1 and a tooth assembly 2, the cloth belt assembly 1 is provided with a core layer 11 and a waterproof layer 12 completely covering the outside of the core layer 11, and the edge of the cloth belt assembly 1 has an implant area 101 with a raised structure 13; the tooth assembly 2 is arranged on the cloth belt assembly 1, and the tooth assembly 2 includes teeth 21 arranged along the implant area 101, and the interior of the tooth 21 is interlocked with the raised structure 13.

[0044] In the prior art, the realization of waterproof zippers mainly relies on making holes at the edge of the tape and then implanting teeth, and enhancing the waterproof performance by coating with elastomeric resin. However, this method has some obvious defects, such as the strict control of the hole size, the possible gaps at the holes, and the possible weakening of the tape material. These problems not only affect the waterproof performance of the zipper, but also reduce its overall durability and reliability.

[0045] In response to these technical problems, the technical solution of the chain belt provided by the present application has been innovatively improved. First, by providing a waterproof layer 12 that completely covers the core layer 11 on the cloth belt assembly 1, the waterproof performance of the zipper is fundamentally enhanced. Secondly, a raised structure 13 is provided in the edge implant area 101 of the cloth belt assembly 1. These raised structures 13 are interlocked with the inside of the teeth 21 to form a mechanical combination. This combination not only improves the horizontal pulling strength of the teeth 21, but also avoids the weakening of the cloth belt material that may be caused by making holes because there is no need to make holes in the cloth belt. In addition, due to the interlocking of the raised structure 13 and the teeth 21, the gap problem that may be caused by making holes for implants is eliminated, which further improves the reliability of the zipper when it is repeatedly used and subjected to large tension.

[0046] In combination with the above structure and process description, it can be seen that the link tooth belt has at least the following beneficial effects: the link tooth belt is provided with a waterproof layer 12 to cover the cloth belt assembly 1 with a core layer 11, and a protruding structure 13 is provided in the implant area 101 of the cloth belt assembly 1 and the teeth 21 are embedded therein, thereby enhancing the waterproof performance of the zipper and improving the horizontal pulling strength of the teeth 21, avoiding the weakening of the cloth belt material due to hole extraction and implantation and the gap problem that may occur during use, thereby improving the overall durability and reliability of the zipper.

[0047] In some embodiments, the dental implant area 101 includes a first area located on the front side of the tape assembly 1 and a second area located on the back side of the tape assembly 1. Figure 3 As shown, the first area of ​​the dental implant area 101 and the second area of ​​the dental implant area 101 are located on two different sides of the cloth belt assembly 1, which can be called the front and back sides of the cloth belt assembly 1, or the front and reverse sides, which have the same meaning.

[0048] In some embodiments, the material of the core layer 11 is resin.

[0049] In some embodiments, the waterproof layer 12 is made of transparent resin.

[0050] like Figure 3 As shown, the tape core layer 11 can be regarded as a sandwich layer of the waterproof layer 12 in the length, width and thickness directions. The waterproof layer 12 uses a transparent resin with good softness to cover the tape core layer 11. This design not only strengthens the cloth tape, but also has the advantage of being environmentally friendly because the transparent resin does not need to be dyed. The tape core layer 11 uses the same resin as the traditional resin zipper.

[0051] In a specific embodiment, the dental implant area 101 is designed to include two parts: a first area located on the front side of the tape assembly 1 and a second area located on the back side. Such a design allows different implementation schemes to meet specific application requirements.

[0052] In some embodiments, the first region or the second region is provided with a protruding structure 13 , and a single surface inside the tooth 21 is engaged with the protruding structure 13 .

[0053] In this embodiment, only one of the first area or the second area is provided with the protruding structure 13. This design means that only one side of the interior of the tooth 21 is engaged with the protruding structure 13. Such a single-sided engagement may be used in application scenarios that do not require excessively high horizontal pulling strength, or in certain specific designs, the single-sided engagement is sufficient to provide the required connection strength and stability.

[0054] In some other embodiments, both the first region and the second region are provided with protruding structures 13 , and the double surfaces inside the teeth 21 are engaged with the protruding structures 13 at corresponding positions.

[0055] In this embodiment, in order to enhance the strength and stability of the connection, the first area and the second area are both provided with a protruding structure 13. In this case, the inner double sides of the teeth 21 will be correspondingly engaged with the protruding structures 13 in the two areas. The double-sided engagement design is suitable for application scenarios requiring higher flat pulling strength and higher strength, providing a more secure connection, ensuring that the zipper can still maintain its structural integrity and functional effectiveness when subjected to a large pulling force.

[0056] Please refer to Figure 4 and Figure 5 , Figure 4 This is a structural diagram of a chain link belt provided in the first embodiment of the present application. Figure 5 A structural diagram of a link belt provided for the second embodiment of the present application.

[0057] In some embodiments, Figure 4 As shown, the cross-sectional shape of the protruding structure 13 is circular. Optionally, the protruding structure 13 is a truncated cone.

[0058] In this embodiment, the cross-section of the protrusion structure 13 is designed to be circular, which can provide uniform stress distribution. When the teeth 21 are engaged with these protrusion structures, local stress concentration can be reduced, thereby reducing material fatigue and potential damage risks. In addition, the circular design may also help simplify the manufacturing process because the circular cross-section is easier to obtain through mold processing.

[0059] In some embodiments, Figure 5 As shown, the cross-sectional shape of the protruding structure 13 is a square. Optionally, the protruding structure 13 is a square platform.

[0060] In this embodiment, the cross-section of the protrusion structure 13 is designed to be square, which provides a different mechanical property. They may provide a larger contact area when they are engaged, which can increase the friction between the teeth 21 and the protrusion structure 13, thereby improving the stability and strength of the connection. The square design may also provide better adaptability in certain specific structural designs, such as when specific alignment or directionality is required.

[0061] Preferably, the cross-sectional shape of the raised structure 13 is square and is close to the shape of the tooth 21. After the tooth 21 is implanted, it is most reasonable for the tooth 21 to wrap the raised structure 13. The tooth 21 and the raised structure 13 form a whole, and the horizontal pulling strength will be maximized.

[0062] In some embodiments, the protruding structure 13 is formed on the dental implant area 101 by die casting.

[0063] In this embodiment, the protruding structure 13 is formed by die casting, which allows the protruding structure required by the design to be accurately manufactured on the implant area 101, ensuring that the size and shape of each protruding structure meet the specification requirements. Die casting is an efficient production technology that can not only improve production efficiency, but also improve product consistency and reliability. In addition, by replacing or adjusting the mold, the design of the protruding structure 13 can be easily changed to adapt to different application scenarios and performance requirements.

[0064] As an option, the protruding structures 13 are die-casted on both the front and back sides of the tape assembly 1, namely the first area and the second area of ​​the dental implant area 101, and the protruding structures 13 on both sides are symmetrical.

[0065] Please refer to Figure 6 , Figure 6 This is an exploded view of the teeth and fabric belt assembly provided in an embodiment of the present application.

[0066] In some embodiments, Figure 4 and Figure 5 As shown, the tooth 21 includes a head 211 and a pair of roots 212 connected to the head 211. Figure 6 As shown, a pair of roots 212 are distributed on the front and back sides of the tape assembly 1 , and the roots 212 are provided with a recessed structure 2121 engaged with the raised structure 13 .

[0067] As an option, continuing to take the example that both the first area and the second area of ​​the dental implant area 101 are provided with a protruding structure 13 , a pair of roots 212 are both provided with a recessed structure 2121 that is engaged with the protruding structure 13 .

[0068] In some embodiments, the thickness of the protruding structure 13 is greater than 10% and not greater than 50% of the thickness of the root portion. This design ensures that the engagement between the protruding structure 13 and the root portion 212 is both firm and stable, which helps to improve the overall durability and adaptability of the chain element tape.

[0069] In some embodiments, the recessed structure 2121 is located in the engagement structure 2122 where the root 212 is combined with the tape assembly 1, and the area of ​​the end surface of the protruding structure 13 accounts for less than 50% of the area of ​​the engagement structure 2122. Such a design helps to provide a tight engagement relationship while maintaining a suitable size ratio between the root 212 and the protruding structure 13, which helps to improve the overall durability and adaptability of the chain tooth tape.

[0070] In some embodiments, a set angle 1301 is formed between the height side surface of the protruding structure 13 and the tape assembly 1 , and the set angle 1301 is within a closed interval of 95° to 100°.

[0071] In this embodiment, if Figure 6As shown, ∠A is the angle formed by the height side of the protruding structure 13 and the cloth belt assembly 1. On the one hand, reducing the degree of ∠A can optimize the interlocking effect between the protruding structure 13 and the tooth 21. On the other hand, increasing the degree of ∠A helps to reduce the complexity of the manufacturing process. Therefore, the optimal value range of ∠A is 95° to 100°, and the corresponding demoulding angle is 5° to 10°.

[0072] The present application also provides a zipper, comprising a slider and the above-mentioned chain tooth tape.

[0073] The zipper includes the above-mentioned chain element tape and should have all the beneficial effects of the above-mentioned chain element tape; the zipper is specifically an airtight and waterproof zipper.

[0074] The present application is to use a waterproof layer 12 to cover a tape assembly 1 with a core layer 11, and to set a dental implant area 101 at the edge of the tape assembly 1. A protruding structure 13 is die-cast in the dental implant area 101 in advance. The protruding structure 13 is higher than the front and back sides of the tape assembly 1. The protruding structures are arranged according to a certain rule. The distance between the centers of the protruding structures 13 and the protruding structures 13 is the same as the distance between the centers of the teeth 21 and the teeth 21. During dental implantation, the tape assembly 1 is positioned, and the teeth 21 are aligned with the protruding structure 13 for dental implantation, so that a pair of roots 212 of the teeth 21 are integrated with the protruding structures 13 on the front and back sides of the tape assembly 1. The protruding structures 13 arranged after dental implantation act as the tape ribs, and the strength of the teeth 21 when pulled horizontally is increased, and the two sides of the tape can be squeezed together. After the teeth 21 and the tape assembly 1 are pulled horizontally, the gap is greatly reduced, or even eliminated, and the airtight and waterproof effect is better.

[0075] The present application also provides a kind of clothing, packaging and tent, all of which include the above-mentioned zipper and should have all the beneficial effects of the above-mentioned chain tooth belt, which will not be described in detail here.

[0076] Exemplarily, the clothing is light clothing, such as sun protection clothing, skin clothing, light down jackets, etc.

[0077] It should be noted that many of the components mentioned in this application are universal standard parts or components known to those skilled in the art, and their structures and principles can be learned by those skilled in the art through technical manuals or through conventional experimental methods.

[0078] It should be noted that, in this specification, relational terms such as first and second are merely used to distinguish one entity from other entities, but do not necessarily require or imply any actual relationship or order between these entities.

[0079] The above is a detailed introduction to the chain element belt, zipper, clothing, packaging and tent provided by the present application.
