Description

Technical Field

[0001] This utility model relates to the field of zipper technology, specifically a protective zipper. Background Technology

[0002] Zippers, as a common connector, are widely used in various products such as clothing, bags, and tents. They mainly consist of a chain strap, chain teeth, a zipper pull, and a zipper tab. Chain teeth are distributed along the inner edges of two parallel chain straps. The zipper pull is fitted onto the chain teeth and can slide along the chain strap. By pulling the zipper tab connected to the zipper pull, the zipper pull can be moved to engage or disengage the chain teeth on both sides, thereby opening and closing the product opening and bringing great convenience to people's lives.

[0003] However, current zippers have some problems in use. On the one hand, the chain teeth are directly exposed, making them prone to dust, moisture, and other debris, which can cause them to jam or corrode, affecting the normal use of the zipper. At the same time, the chain teeth are also prone to direct friction with other objects, causing wear and deformation, and shortening the zipper's lifespan. On the other hand, the pull tab is usually directly attached to the outside of the zipper pull and protrudes noticeably. During use or carrying, it is easy for it to snag or collide with other objects, potentially damaging the pull tab and causing the zipper to open unexpectedly, resulting in inconvenience. Utility Model Content

[0025] 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.

[0026] like Figure 1-3 As shown, this utility model provides a protective zipper that can effectively protect the chain teeth 2 and the pull tab 4. The protective zipper is mainly composed of two parallel chain straps 1, chain teeth 2, zipper head 3, pull tab 4, protective strip 5, disassembly component 6, and protective clip 7.

[0027] Chain strap 1, as the basic load-bearing part of the zipper, is made of fabric with a certain toughness and strength. The two chain straps 1 are placed in parallel to provide a stable foundation for the installation of subsequent components.

[0028] The chain teeth 2 are located on the inner edges of the two chain straps 1 and are staggered along the edges of the two chain straps 1. This staggered distribution is the key to the zipper's closing function, allowing the chain teeth 2 on both sides to mesh with each other under the sliding action of the slider 3, thereby closing the zipper. The chain teeth 2 are made of metal, which has high hardness and wear resistance, ensuring that the zipper is not easily damaged during long-term use.

[0029] The slider 3 is fitted onto the chain teeth 2 on both sides and can slide along the chain belt 1. The internal structure of the slider 3 matches the chain teeth 2, and when the slider 3 slides, it can drive the chain teeth 2 on both sides to engage or disengage. The slider 3 is made of alloy material, which has good strength and corrosion resistance.

[0030] Pull tab 4 is connected to the pull head 3, making it convenient for users to pull the pull head 3. Pull tab 4 is made of plastic, which is lightweight and has a certain degree of elasticity, making it comfortable to use.

[0031] The protective tape 5 extends along the length of the chain belt 1 to cover the chain teeth 2. Made of waterproof fabric, the protective tape 5 not only prevents dust and moisture from entering the chain teeth 2 but also avoids damage from direct friction between the chain teeth 2 and other objects. One side of the protective tape 5 is securely connected to one of the chain belts 1 via a sewn connection; this secure connection ensures that the protective tape 5 will not separate from the chain belt 1 during use. The other side of the protective tape 5 is detachably connected to another chain belt 1 via a disassembly assembly 6.

[0032] The disassembly assembly 6 includes a first hook and loop fastener 601 disposed on the protective belt 5 and a second hook and loop fastener 602 disposed on the chain belt 1 to cooperate with the first hook and loop fastener 601. Both the first hook and loop fastener 601 and the second hook and loop fastener 602 extend along the length of the chain belt 1. The hook and loop fastener connection method is simple to operate, and users can easily connect or disconnect the protective belt 5 from another chain belt 1, which facilitates cleaning or maintenance of the chain teeth 2.

[0033] The protective strip 5 is also provided with a protective clip 7 extending along the length of the chain 1 on the end face near the chain tooth 2. The protective clip 7 is made of silicone, which has good elasticity and flexibility, and is fixed to the protective strip 5 by sewing, so that the connection is firm.

[0034] The protective strip 7 has grooves 701 along its length that engage with the chain teeth 2 on both sides. Anti-slip surfaces 702 are provided on both sides of the grooves 701. The anti-slip surfaces 702 have a rough surface design, which increases the friction between the protective strip 7 and the chain teeth 2, making the engagement between the protective strip 7 and the chain teeth 2 more secure and less prone to relative slippage. When the pull head 3 slides and closes the chain teeth 2 on both sides, the protective strip 5 can cover the chain teeth 2 and engage with them through the grooves 701 on the protective strip 7, further enhancing the protective effect on the chain teeth 2.

[0035] The top of the zipper pull 3 has a receiving groove 301 for accommodating the pull tab 4. The two inner walls of the receiving groove 301 are symmetrically provided with rotating grooves 302. The pull tab 4 has protruding engaging parts 401 on both sides. The pull tab 4 is connected and flipped by engaging the engaging parts 401 with the rotating grooves 302. This connection method allows the pull tab 4 to flip relative to the zipper pull 3, making it convenient for users to adjust the angle of the pull tab 4 according to different usage habits and scenarios.

[0036] The end of the pull tab 4 away from the latch 401 is located in the receiving groove 301 and extends outward from the pull head 3. This design ensures that the pull tab 4 can be easily pulled by the user, and also prevents the pull tab 4 from protruding excessively when not in use and getting caught on other objects, thus providing a good protective effect for the entire pull tab 4.

[0037] When in use, to close the zipper, the user pulls the pull tab 4, causing the zipper head 3 to slide along the chain belt 1 in the closing direction. Under the action of the zipper head 3, the staggered chain teeth 2 on both sides mesh with each other, realizing the zipper closure. At this time, the side of the protective strip 5 with the first Velcro 601 is attached to the second Velcro 602 on the other chain belt 1, so that the protective strip 5 covers the chain teeth 2. At the same time, the slot 701 on the protective strip 7 engages with the closed chain teeth 2, and the anti-slip surface 702 increases the friction between the two, ensuring that the protective strip 5 firmly covers the chain teeth 2, effectively protecting the chain teeth 2.

[0038] When the zipper needs to be opened, first separate the first Velcro 601 and the second Velcro 602 on the protective strap 5, so that the protective strap 5 no longer covers the chain teeth 2. Then pull the pull tab 4, causing the zipper head 3 to slide along the chain strap 1 in the opening direction. Under the action of the zipper head 3, the interlocking chain teeth 2 separate, thus opening the zipper. Throughout the entire use, the pull tab 4 can be flipped within the rotating groove 302 of the zipper head 3 via the locking part 401, making it convenient for the user to operate.

[0039] Compared with traditional technology, the zipper provided by this technology adds a protective strip 5 to the chain belt 1 to cover the chain teeth 2. At the same time, the protective strip 5 is equipped with a protective strip 7 that engages with the chain teeth 2, which can fully protect the chain teeth 2, isolate dust, moisture, etc., and avoid friction-induced wear and deformation. The zipper head 3 is provided with a receiving groove 301 to accommodate the zipper pull 4. The receiving groove 301 can protect the zipper pull 4, reduce the excessive protrusion of the zipper pull 4, and reduce the risk of damage caused by collision.

[0040] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within this invention, and no reference numerals in the claims should be construed as limiting the scope of the claims.
