Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of zippers, and particularly relates to a rain-proof waterproof zipper, which is especially suitable for clothes, bags and other outdoor equipment that require high waterproof performance. BACKGROUND

[0002] In the current waterproof zipper technology, the initial waterproof performance is generally excellent, which can effectively prevent water penetration within a certain period of time, meeting the basic needs of users for waterproof function. The realization of such waterproof performance mainly depends on two key factors: one is the tight engagement design between the zipper teeth, and the other is the waterproof coating or waterproof structure of the outer layer. The tight engagement between the zipper teeth is realized through precise manufacturing process, so that there is almost no gap between the teeth, thereby effectively blocking the intrusion of water in the initial stage. At the same time, the waterproof coating or structure design of the outer layer further enhances the waterproof effect, for example, using high molecular material coating or film technology, so that a waterproof barrier is formed on the surface of the zipper to prevent water from penetrating from the outside. Such double waterproof mechanism performs well in the initial use stage of the zipper, which can cope with daily rain or humid environment.

[0003] However, as the use time goes on, the wear and tear problem between the zipper teeth gradually appears, which leads to a significant decline in waterproof performance, and even complete failure. Such wear and tear mainly comes from two aspects: one is that in the process of frequent opening and closing of the zipper, the friction between the teeth is inevitable, especially in high-intensity use scenarios such as outdoor sports equipment or travel bags, the opening and closing frequency of the zipper is higher, and the physical loss between the teeth is more obvious. Such friction will cause the teeth surface to gradually wear and tear, and the engagement between the teeth will no longer be tight, thus forming a small gap through which water can penetrate. The second is the influence of external environmental factors, such as rain, dust, sand and other small particulate matter that can enter the zipper teeth, further aggravating the wear and tear, and even causing the teeth surface to corrode or deform. The cumulative effect of such wear and tear and corrosion makes the waterproof performance of the zipper gradually decay, and eventually fails to meet the needs of users. Such performance decay not only reduces the practicability of the zipper, but also increases the maintenance cost and inconvenience of users, such as the need to frequently replace the zipper or perform additional waterproof treatment.

[0004] Moreover, existing waterproof zipper designs often focus too much on the waterproof structure of the outer layer, which to some extent limits the appearance design of the clothing or luggage. In order to achieve waterproof function, many waterproof zippers use thick waterproof coating or complex waterproof structure on the outer layer, such as multi-layer film or sealing strip design. These designs, although improving waterproof performance, also increase the volume and weight of the zipper, limiting its application on clothing or luggage. While pursuing waterproof performance, designers have to sacrifice part of the appearance beauty or design freedom. For example, in order to adapt to the thick structure of the waterproof zipper, the style of the clothing may need to be simplified, and the appearance design of the luggage may tend to be conservative, making it difficult to express fashion or individuality. This compromise in design not only affects the overall appearance of the product, but also may limit its application in high-end markets or fashion fields. For example, in high-end outdoor clothing or luxury luggage, consumers not only pay attention to functionality, but also pay attention to the design sense and brand value of the product, and the existing waterproof zipper design is difficult to meet the needs of these high-end markets.

[0005] In view of the above problems, it is of great practical significance and market value to develop a new type of rain-proof waterproof zipper. Content of the utility model

[0006] The purpose of the present application is to at least overcome the shortcomings of the prior art, and to provide a rain-proof waterproof zipper. The zipper solves the problem of decline in waterproof performance caused by long-term use of existing waterproof zippers by improving the structural design of the waterproof secondary belt, magnetic powder silica gel strip and glue layer, while taking into account the flexibility and aesthetics of the appearance design.

[0007] To achieve the above-mentioned purpose, the present application discloses a rain-proof waterproof zipper, comprising a first zipper tape and a second zipper tape, which are oppositely arranged and have zipper teeth arranged on the edges thereof. The zipper head cooperates with the zipper teeth on the first zipper tape and the second zipper tape to control the opening and closing operation of the zipper. A waterproof secondary belt made of waterproof cloth is arranged on the bottom of the first zipper tape. One side edge of the waterproof secondary belt is fixedly connected to the edge of the first zipper tape by hot pressing process, and the other side edge is provided with a first magnetic powder silica gel strip. Correspondingly, the second zipper tape is provided with a second magnetic powder silica gel strip with opposite magnetic poles to the first magnetic powder silica gel strip, and the waterproof secondary belt and the first zipper tape are tightly attached by magnetic force, thereby enhancing the waterproof performance of the zipper.

[0008] Further, the inner side of the waterproof auxiliary belt is provided with a glue layer, which is uniformly coated on the inner surface of the waterproof auxiliary belt through a hot melt process and forms a firm adhesion with the bottom of the first zipper belt. The material of the glue layer is hot melt glue, which has excellent waterproof performance and structural toughness, and can effectively resist external environmental erosion and physical wear and tear during long-term use. The thickness of the glue layer is 0.1-0.3mm, which ensures the waterproof performance and does not increase the overall thickness of the zipper. In addition, the glue layer also has a certain elasticity, which can adapt to the deformation of the waterproof auxiliary belt during the opening and closing of the zipper, preventing the glue layer from cracking or falling off.

[0009] Specifically, the material of the waterproof auxiliary belt is high-density waterproof cloth, and the surface is treated with a polyurethane coating, which has excellent waterproof performance and wear resistance. The width of the waterproof auxiliary belt is slightly larger than that of the first zipper belt to ensure that it can completely cover the gap between the zipper teeth and prevent water from penetrating. The first and second magnetic powder silica gel strips are respectively embedded in the edges of the waterproof auxiliary belt and the first zipper belt, and the two are tightly attached through magnetic force. The material of the magnetic powder silica gel strip is flexible silica gel, which is uniformly distributed with magnetic particles inside, which can provide stable magnetic force while ensuring flexibility.

[0010] Further, the magnetic force between the first and second magnetic powder silica gel strips not only realizes the rapid positioning and fixing of the waterproof auxiliary belt, but also ensures the tight contact between the waterproof auxiliary belt and the zipper belt during the opening and closing of the zipper, preventing water from penetrating between the zipper teeth. The magnetic poles of the first and second magnetic powder silica gel strips are oppositely arranged, so that they can automatically attract each other when they are close, forming a seamless connection. In addition, the surface of the magnetic powder silica gel strip is treated with anti-slip to enhance the friction between it and the waterproof auxiliary belt and the first zipper belt, preventing displacement during the opening and closing of the zipper.

[0011] The present application significantly improves the waterproof performance of the zipper through the synergistic effect of the waterproof auxiliary belt, the magnetic powder silica gel strip and the glue layer, especially in the case of long-term use and high-frequency opening and closing, which can effectively prevent the decrease of waterproof performance caused by wear between the zipper teeth. At the same time, on the basis of ensuring the waterproof performance, the structure design of the zipper is optimized, making its application in clothing or luggage more flexible, providing more possibilities for the appearance design of the product.

[0012] The above-listed advantages are not exhaustive of all advantages. Other potential advantages and detailed technical implementation methods will be further disclosed in the examples or other description parts of the present application. BRIEF DESCRIPTION OF DRAWINGS

[0022] Embodiment:

[0023] Referring to the accompanying drawings Figs. 1 to 3The embodiment discloses a rain-proof waterproof zipper structure, which comprises a first zipper tape 1, a second zipper tape 2, zipper teeth 3, a zipper head 4, a waterproof auxiliary tape 5, a first magnetic powder silica gel strip 6, a second magnetic powder silica gel strip 7 and a glue layer 8.

[0024] The first zipper tape 1 is oppositely arranged with the second zipper tape 2, and the edges of the two are respectively arranged with the zipper teeth 3.

[0025] The bottom of the first zipper tape 1 is provided with the waterproof auxiliary tape 5 made of waterproof cloth, one side edge of the waterproof auxiliary tape 5 is fixedly connected with the first zipper tape 1 through a hot pressing process, and the other side edge is provided with the first magnetic powder silica gel strip 6.

[0026] The second zipper tape 2 is provided with the second magnetic powder silica gel strip 7 opposite to the magnetic pole of the first magnetic powder silica gel strip 6, and the waterproof auxiliary tape 5 and the first zipper tape 1 are tightly attached through magnetic force.

[0027] Further, the waterproof auxiliary tape 5 is made of high-density waterproof cloth, and the surface of the waterproof auxiliary tape 5 is treated by a polyurethane coating process, so that the waterproof auxiliary tape 5 has excellent waterproof performance and wear resistance.

[0028] The width of the waterproof auxiliary tape 5 is slightly larger than the width of the first zipper tape 1, so that the waterproof auxiliary tape 5 can completely cover the gap between the zipper teeth 3 and prevent water from penetrating.

[0029] The first magnetic powder silica gel strip 6 and the second magnetic powder silica gel strip 7 are respectively embedded in the edges of the waterproof auxiliary tape 5 and the first zipper tape 1, and the two are tightly attached through magnetic force.

[0030] The material of the magnetic powder silica gel strip is flexible silica gel, and the magnetic particles are uniformly distributed in the flexible silica gel, so that the flexible silica gel can provide stable magnetic force while ensuring flexibility.

[0031] The magnetic poles of the first magnetic powder silica gel strip 6 and the second magnetic powder silica gel strip 7 are oppositely arranged, so that the two can be automatically attracted when they are close to each other, forming a seamless connection.

[0032] Specifically, the material of the glue layer 8 is hot melt glue, which is uniformly coated on the inner surface of the waterproof auxiliary tape 5 through a hot melting process, and is firmly bonded with the bottom of the first zipper tape 1.

[0033] The thickness of the glue layer 8 is 0.1-0.3 mm, which ensures the waterproof performance and does not increase the overall thickness of the zipper. The glue layer 8 also has a certain elasticity, which can adapt to the deformation of the waterproof secondary belt 5 during the opening and closing of the zipper, preventing the glue layer 8 from cracking or falling off. The hot melt adhesive has excellent bonding performance and can maintain stability in high temperature and humid environments, ensuring that the waterproof performance of the zipper does not decrease during long-term use.

[0034] For example, in outdoor sports clothing or travel bags, this rain-proof zipper can effectively prevent rainwater from penetrating and protect the internal items from getting wet. During the opening and closing process, the zipper head 4 ensures that water cannot penetrate between the zipper teeth 3 by engaging the zipper teeth 3 and tightly fitting the waterproof secondary belt 5. The high-density waterproof cloth and polyurethane coating treatment of the waterproof secondary belt 5 enable it to maintain excellent waterproof performance in harsh environments. The magnetic cooperation of the first and second magnetic silicone strips 6 and 7 allows the waterproof secondary belt 5 to be quickly positioned and fixed, ensuring that the waterproof secondary belt 5 and the zipper belt 1 are in close contact during the opening and closing process. The hot melt adhesive material and uniform coating process of the glue layer 8 further enhance the structural toughness and waterproof performance of the waterproof secondary belt 5, allowing it to remain stable even in long-term use and high-frequency opening and closing.

[0035] To further improve the effect, the design of this rain-proof zipper also considers the appearance and design flexibility. The width and thickness of the waterproof secondary belt 5 are optimized to ensure waterproof performance without limiting the appearance design of the clothing or bag. The flexible material and anti-slip treatment of the magnetic silicone strips make the zipper smoother during opening and closing, while avoiding wear caused by friction. The hot melt adhesive material and uniform coating process of the glue layer 8 not only improve waterproof performance but also enhance the overall structural strength of the zipper, allowing it to remain stable during long-term use.

[0036] Compared with the prior art, this rain-proof zipper significantly improves the waterproof performance of the zipper through the cooperation of the waterproof secondary belt 5, magnetic silicone strips 6 and 7, and glue layer 8, especially in long-term use and high-frequency opening and closing, effectively preventing a decrease in waterproof performance caused by wear between the zipper teeth 3. At the same time, this technical solution optimizes the structural design of the zipper while ensuring waterproof performance, making it more flexible in clothing or bag applications and providing more possibilities for product appearance design.

[0037] It should be noted that parts not disclosed in detail in this embodiment, such as the specific shape of the zipper teeth 3, the internal structure of the zipper head 4, and the specific parameters of the hot pressing process, are all known to those skilled in the art or existing technology and do not need to be described in detail in this embodiment.
