Description

Technical Field

[0001] This utility model relates to the field of waterproof zipper technology, and in particular to a zipper pull and a waterproof zipper. Background Technology

[0002] In outdoor environments, ordinary zippers have gaps between the teeth and at the junction of the zipper pull and the zipper fabric, allowing water to easily seep in. This can cause clothing and items in bags to become damp, affecting usability and even causing damage. To address the waterproofing issue of ordinary zippers, early waterproof zippers often achieved basic waterproofing by coating the zipper fabric edges with a waterproof coating and ensuring the teeth meshed tightly. However, this method requires high precision in the manufacturing of the teeth, and the coating is prone to wear after prolonged use, leading to a decrease in waterproofing performance. Current waterproof zippers typically have a rubber sealing strip along the edge of the zipper strap. When the zipper is closed, the zipper pull presses against the rubber sealing strip, ensuring a tight seal and preventing water penetration.

[0003] However, existing zipper pulls still have the following drawbacks: the chain teeth on both sides at the core position are separated by the core, thus separating the center seam of the zipper fabric and creating a gap between it and the core. Water seepage still occurs at this gap, resulting in a significant decrease in the zipper's waterproof performance. Therefore, a zipper pull and waterproof zipper designed to solve the above problems are proposed. Utility Model Content

[0004] The purpose of this invention is to provide a zipper pull and a waterproof zipper, which solves the technical problem that in existing zipper pulls, the chain teeth on both sides at the base core position are separated by the base core, thereby separating the center seam of the chain fabric and forming a gap with the base core, resulting in water seepage at the gap position, which leads to a significant decrease in the waterproof performance of the zipper.

[0005] To achieve the above objectives, this utility model provides a zipper pull and a waterproof zipper. The zipper pull includes: a top plate and a bottom plate connected by a base core. An inner cavity is formed between the top plate and the bottom plate. The base core and the inner cavity form a tooth channel. A mating part is provided on the inner surface of the top plate, protruding downwards. The first end of the mating part extends to the outer peripheral side of the base core, and the second end of the mating part extends toward the front end of the top plate. When the zipper pull is closed, the bottom surface of the mating part is always in close contact with the adjacent edges of the left and right zipper fabrics.

[0006] Preferably, the sum of the thickness of the mating part, the thickness of the chain tooth, and the thickness of the chain cloth is less than or equal to the height of the inner cavity of the zipper pull.

[0007] Preferably, the thickness of the mating part is between 0.00 and 1.00 mm.

[0008] Preferably, the second end of the mating part does not extend to the front end face of the pull head plate.

[0009] Preferably, the end face of the second end of the mating part is flush with the front end face of the pull head plate.

[0010] Preferably, the second end of the mating part extends out of the front end face of the pull head plate.

[0011] Preferably, the width of the first end of the mating portion is greater than or equal to the width of the second end of the mating portion.

[0012] Preferably, the front end face of the base core connected to the upper plate of the pull-top is tapered, and the first end of the mating part extends to a position not exceeding the maximum width of the connection surface between the base core and the upper plate of the pull-top.

[0013] A zipper includes a zipper head as described in any of the above claims, and further includes two chain fabrics arranged side by side, with chain teeth provided on the edges of adjacent sides of the two chain fabrics, the zipper head being used to engage and disengage the chain teeth on both sides to realize the opening and closing of the zipper.

[0014] Preferably, a waterproof membrane is provided on the outer surface of the chain fabric.

[0015] Compared with the above-mentioned background technology, the zipper pull provided by this utility model has the following beneficial effects: a mating part is provided with a downward protrusion on the inner surface of the zipper pull plate. When the zipper pull is pulled or closed, the bottom surface of the mating part is always in close contact with the adjacent edges of the left and right chain fabrics. This allows the bottom surface of the mating part to be in close contact with the area of ​​the chain fabrics around the mating gap, so that the circumferential direction of the mating gap is fully wrapped and sealed to block the path of water seepage from the mating gap and effectively improve the waterproof performance of the zipper.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] To enable those skilled in the art to better understand the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0028] like Figure 1 , Figure 2 and Figure 3As shown, to achieve the above objectives, this utility model provides a zipper pull, comprising: a zipper pull upper plate 101 and a zipper pull lower plate 102 connected together by a base core 104. The bottom surface of the zipper pull upper plate 101 and the top surface of the zipper pull lower plate 102 are parallel. A zipper pull inner cavity 103 is formed between the zipper pull upper plate 101 and the zipper pull lower plate 102. The base core 104 and the zipper pull inner cavity 103 form a zipper tooth 4 channel. The zipper pull inner cavity 103 is used for the passage of the zipper tooth 4. A mating part 105 is provided at the top of the zipper pull inner cavity 103. The bottom surface of the mating part 105 is simultaneously in close contact with the outer surfaces of the two chain fabrics 3. Even if the chain teeth 4 on both sides of the zipper pull 1 base core 104 are separated by the base core 104, forming a fitting gap 301 between the chain cloth 3 and the base core 104, by providing a fitting part 105 that protrudes downward on the inner surface of the zipper pull plate 101, when the zipper pull 1 is pulled, the bottom surface of the fitting part 105 is always in close contact with the adjacent edges of the left and right chain cloths 3, so that the bottom surface of the fitting part 105 can be in close contact with the area of ​​the chain cloth 3 located around the fitting gap 301, so that the circumferential direction of the fitting gap 301 is fully wrapped and sealed to block the path of water seepage from the fitting gap 301, effectively improving the waterproof performance of the zipper. It should be noted that the bottom surface of the mating part 105 protrudes from the bottom surface of the top plate 101 of the zipper pull, so that the mating part 105 can be more accurately aligned with the surrounding area of ​​the mating gap 301 on the chain cloth 3, compensating for any possible gaps between the bottom surface of the top plate 101 of the zipper pull and the outer surface of the chain cloth 3, so that the mating part 105 and the chain cloth 3 form a stable and tight fit, ensuring the waterproof performance of the zipper.

[0029] In some specific embodiments, the first end of the mating part 105 extends to the outer peripheral side of the base core 104, and the second end of the mating part 105 extends toward the front end of the zipper head plate 101. The base core 104 is the core component inside the zipper head 1 that mates with the chain teeth 4. Its outer peripheral side is the key contact area when the chain teeth 4 are engaged. By extending the first end of the mating part 105 to the outer peripheral side of the base core 104, the mating part 105 and the base core 104 form a seamless whole, thereby avoiding the formation of new gaps at the joint between the mating part 105 and the base core 104. This improves the all-round wrapping seal of the mating gap 301, reduces the risk of moisture seeping in from the joint gap, and ensures the overall waterproof effect of the zipper. On the other hand, since the mating part 105 and the base core 104 form a seamless whole, the stable structure of the base core 104 itself can provide a stable support effect for the first end of the mating part 105, avoiding problems such as frequent sliding of the pull head 1, shaking, displacement or even breakage of the mating part 105 due to insufficient support, and effectively improving the structural stability and durability of the mating part 105.

[0030] It should be noted that when the zipper pull 1 is at various positions along the length of the zipper, the mating part 105 is always in close contact with the area around the mating gap 301 of the zipper fabric 3. The mating part 105 is not only in close contact with the area around the mating gap 301 of the zipper fabric 3 when the zipper pull 1 moves to the top stop of the zipper and the top stop of the zipper (not shown in the figure) enters the inner cavity 103 of the zipper pull, thereby ensuring the local waterproof performance at the location of the zipper pull 1.

[0031] like Figure 5 As shown, in some embodiments of this utility model, the sum of the thickness of the mating part 105, the thickness of the chain tooth 4, and the thickness of the chain cloth 3 is less than or equal to the height of the inner cavity 103 of the zipper head. This allows for a reasonable assembly space to be reserved for the sliding of the zipper head 1, preventing the chain tooth 4, chain cloth 3, and mating part 105 from being squeezed or jammed due to the thickness of the chain tooth 4, chain cloth 3, and mating part 105 exceeding the height of the inner cavity 103 of the zipper head. This ensures the smoothness of the zipper head 1 when sliding, avoids situations such as clothing being pulled due to zipper jamming, and effectively improves the user experience of the zipper.

[0032] It should be noted that by precisely controlling the thickness dimensions of the chain teeth 4, the chain fabric 3, and the mating part 105, abnormal friction and compression between the chain teeth 4 and the inner cavity 103 of the zipper pull, and between the chain fabric 3 and the mating part 105, abnormal friction and compression between the chain teeth 4 and the inner cavity 103 of the zipper pull, and between the chain fabric 3 and the mating part 105 can be reduced. This prevents the chain teeth 4 from deforming or breaking, and also avoids damage, fuzzing, and surface structure damage to the chain fabric 3 due to excessive compression, thereby reducing the wear rate of the zipper and extending the overall service life of the zipper. On the other hand, it ensures that the mating part 105 always maintains an optimal fit with the chain fabric 3, avoiding the sealing performance between the mating part 105 and the chain fabric 3 due to compression and misalignment. This further ensures that the zipper can maintain smooth opening and closing and continue to provide reliable waterproofing during long-term use, effectively improving the stability of the zipper's waterproof performance.

[0033] like Figure 4 As shown, in some embodiments of this utility model, the thickness of the mating part 105 is limited to between 0.00-1.00 mm. This ensures that the mating part 105 has sufficient structural strength, preventing breakage or deformation during the sliding and frequent opening and closing of the slider 1 due to excessive thinness, thus ensuring the structural stability of the mating part 105. At the same time, it does not excessively occupy the space of the slider's inner cavity 103, preventing increased resistance or jamming during the sliding of the slider 1 due to excessive thickness of the mating part 105, and does not affect the smoothness of the slider 1 during sliding as before. On the other hand, improving the precise control of the thickness of the mating part 105 does not require significant changes to the original structure of the slider 1, effectively reducing the difficulty of adjusting the production mold and the manufacturing cost.

[0034] like Figure 6As shown, in the first embodiment of this utility model, the second end of the mating part 105 does not extend to the front end face of the top plate 101 of the zipper pull. While ensuring that the bottom surface of the mating part 105 can be tightly attached to the area around the mating gap 301 of the chain cloth 3, so that the circumferential direction of the mating gap 301 is fully wrapped and sealed, the length of the mating part 105 is minimized as much as possible to reduce the contact resistance between the mating part 105 and the chain cloth 3 during the sliding of the zipper pull 1, and to ensure a smooth feel when the zipper pull 1 slides.

[0035] like Figure 7 As shown, in the second embodiment of this utility model, the end face of the second end of the mating part 105 is flush with the front face of the top plate 101 of the zipper pull, so that the mating part 105 and the front end of the zipper pull 1 form a flush end face. This prevents the mating part 105 from protruding from the front face of the top plate 101 of the zipper pull and colliding or scraping with the chain teeth 4 that are dynamically engaged and disengaged during the opening and closing process. At the same time, it also prevents the mating part 105 from retracting and causing the front end of the top plate 101 of the zipper pull to become concave, thus hindering the chain teeth 4 from smoothly entering the inner cavity 103 of the zipper pull. This ensures that the chain teeth 4 can accurately and smoothly complete the engagement and disengagement actions, ensuring a smooth feel when the zipper pull 1 slides. Moreover, the flush end face between the mating part 105 and the front end of the top plate 101 of the zipper pull makes the overall appearance of the zipper pull 1 more regular and concise, effectively improving the aesthetics of the zipper.

[0036] like Figure 8 As shown, in the third embodiment of this utility model, the second end of the mating part 105 extends out of the front end face of the zipper head plate 101. This allows for pre-fitting with the chain fabric 3 that is about to enter the zipper head cavity 103. Before the chain teeth 4 fully engage, the area surrounding the mating gap 301 on the chain fabric 3 is pre-protected, preventing rainwater, water mist, and other moisture from adhering to the seam of the chain fabric 3 and entering the zipper head 1 with the chain teeth 4, effectively improving the zipper's waterproof performance. Furthermore, the extended mating part 105 provides a guiding effect on the chain teeth 4 and chain fabric 3 about to enter the zipper head 1, helping the chain teeth 4 maintain the correct posture before entering the zipper head cavity 103, avoiding misalignment due to chain tooth 4 deviation, indirectly ensuring the smooth sliding of the zipper head 1, making the zipper opening and closing operation smoother.

[0037] It should be noted that, in the specific design, three design options were selected based on actual conditions: the second end of the mating part 105 does not extend to the front end face of the zipper top plate 101; the end face of the second end of the mating part 105 is flush with the front end face of the zipper top plate 101; and the second end of the mating part 105 extends beyond the front end face of the zipper top plate 101. These options are designed to adapt to different clothing products and thus accurately match the different performance requirements of various types of clothing products for zippers.

[0038] In some embodiments of this utility model, the width of the first end of the mating part 105 is greater than or equal to the width of the second end of the mating part 105. By designing the mating part 105 as a structure with gradually changing or equal width, it is easy to achieve smooth separation between the mating part 105 and the mold, reduce demolding difficulty, and reduce production defects such as edge damage, deformation, and material shortage of the mating part 105 caused by improper demolding, thereby improving the pass rate of the pull head 1 and accelerating demolding efficiency.

[0039] The front end face of the base core 104 connecting to the top plate 101 of the slider is tapered, which provides smooth guidance for the chain teeth 4 to enter the inner cavity 103 of the slider, reduces the resistance when the chain teeth 4 enter the chain tooth 4 channel, and avoids the chain teeth 4 from being blocked due to the excessively wide extension of the mating part 105, thus assisting the chain teeth 4 to complete the meshing action accurately and smoothly. In addition, the first end of the mating part 105 extends to a position that does not exceed the maximum width of the connection surface between the base core 104 and the top plate 101 of the slider, which ensures that the mating part 105 and the front end face of the base core 104 and the top plate 101 of the slider form a continuous transition structure, avoiding interference or rubbing between the mating part 105 and the chain teeth 4 during the guiding process due to the excessive extension of the mating part 105 beyond the width of the connection surface. This allows the mating part 105 to accurately align with the outer peripheral side of the base core 104, ensuring a seamless fit at the joint, thereby further improving the wrap-around sealing effect of the mating gap 301.

[0040] In addition to the rotor structure described above, this utility model also provides a waterproof zipper that includes the rotor structure disclosed in the above embodiments, and further includes two chain fabrics 3 arranged in parallel. The edges of the two chain fabrics 3 adjacent to each other are provided with chain teeth 4. The zipper head 1 is used to engage and disengage the chain teeth 4 on both sides to realize the opening and closing of the zipper. It should be noted that the waterproof zipper in this utility model is preferably a reverse-mounted zipper.

[0041] In some embodiments of this utility model, the upper stop ends of the two chain cloths 3 are respectively provided with upper stops. After the two upper stops enter the inner cavity 103 of the zipper head, they are interlocked with each other, so that water will not seep into the inner side of the zipper from the connection position of the two upper stops. At the same time, the mating part 105 is in close contact with the mating gap 301, further ensuring that water cannot seep in from the position where the zipper head 1 is combined with the chain teeth 4 and the upper stops, effectively improving the overall waterproof performance of the zipper.

[0042] In some embodiments of this utility model, a waterproof membrane 5 is provided on the outer surface of the zipper fabric 3. The waterproof membrane 5 serves as an auxiliary waterproof structure to block water penetration. When the zipper is closed, the mating part 105 simultaneously presses the waterproof membrane 5 and fits it tightly, further improving the waterproof performance of the zipper. Specifically, the waterproof membrane 5 on the outer surface of the zipper fabric 3 acts as the first waterproof barrier, intercepting most of the water in advance and initially preventing water from penetrating into the interior of the zipper fabric 3 and the mating gap 301. Moreover, utilizing the seepage-proof properties of the waterproof membrane 5, it works in conjunction with the mating part 105 to form a wrap-around seal on the mating gap 301, further enhancing the waterproof effect of the zipper.

[0043] It should be noted that the chain teeth 4 are integrally formed or sewn onto the inner side of the chain fabric 3 to ensure that when the zipper is closed, the two chain fabrics 3 can seal the chain teeth 4 on their inner sides, preventing water from entering the inner side of the zipper from the gap between the chain teeth 4 on both sides, so as to achieve the best waterproof effect.

[0044] In summary, by providing a mating part 105 at the top of the inner cavity 103 of the zipper pull, the bottom surface of the mating part 105 can closely adhere to the area of ​​the chain fabric 3 located around the mating gap 301, so that the circumferential direction of the mating gap 301 is fully wrapped and sealed to block the path of moisture seeping in from the mating gap 301, effectively improving the waterproof performance of the zipper.

[0045] It should be noted that in this specification, relational terms such as first and second are used only to distinguish one entity from several other entities, and do not necessarily require or imply any such actual relationship or order between these entities.

[0046] This article uses specific examples to illustrate the principles and implementation methods of this utility model. The descriptions of the above embodiments are only for the purpose of helping to understand the method and core ideas of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made to this utility model without departing from the principles of this utility model, and these improvements and modifications also fall within the protection scope of this utility model.
