Description

Technical Field

[0001] The present invention relates to the technical field of sliding chains, and more particularly to a sliding chain. Background Art

[0002] Sliding chains are a common connection device widely used in clothing, luggage, tents, and other fields to open, close, and connect two components. A traditional sliding chain typically consists of a parent chain and a child chain. The parent chain consists of a parent chain tape and parent chain teeth mounted on it, with a sliding channel within the parent chain teeth. The child chain, on the other hand, consists of a child chain tape and child chain teeth. The sliding portion of the child chain teeth fits within the sliding channel of the parent chain teeth, enabling the child chain to slide on the parent chain.

[0003] In traditional zipper manufacturing, teeth are typically installed using direct punching. Specifically, holes are pre-punched in the zipper tape, and the teeth are then secured to the tape through these holes. While this installation method is simple, it has significant drawbacks in practice. Direct punching relies solely on holes to define the teeth, resulting in a weak connection. This design can easily cause the teeth to loosen or fall off with frequent use or external forces, shortening the zipper's lifespan.

[0004] Therefore, how to solve the problem of insufficient connection strength caused by installing the teeth by punching is an urgent problem to be solved by those skilled in the art. Summary of the Invention

[0033] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0034] In the present invention, unless otherwise expressly specified or limited, the terms "mounted," "connected," "connect," "fixed," etc. should be understood broadly. For example, they may refer to fixed, detachable, or integral connections; mechanical or electrical connections; direct or indirect connections through an intermediary; or internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in the present invention based on specific circumstances.

[0035] It should be noted that the directional words such as "left" and "right" below are defined based on the drawings in the specification.

[0036] The core of the present invention is to provide a sliding chain that can improve the connection strength of the sliding chain.

[0037] Please refer to Figure 1 、 Figure 2 and Figure 3 A sliding chain includes a sliding chain belt 1 and sliding chain teeth 2 arranged on the sliding chain belt 1. Two belt ribs 3 extending along the length direction of the sliding chain belt 1 are provided in the middle of the sliding chain belt 1 to increase the structural strength of the sliding chain belt 1, provide more stable support for the sliding chain teeth 2, and reduce the risk of the sliding chain teeth 2 loosening or falling off due to external force. A number of mounting holes 4 arranged in an array along the length direction of the sliding chain belt 1 are provided between the two belt ribs 3, so that the sliding chain teeth 2 can be evenly distributed on the sliding chain belt 1, ensuring the smooth operation and uniform force of the sliding chain, and improving the operation efficiency and reliability of the sliding chain.

[0038] The sliding chain teeth 2 are provided in the mounting holes 4, and the sliding chain teeth 2 are fixed to the sliding chain tape 1 through the mounting holes 4, ensuring the firmness of the sliding chain teeth 2. The sliding chain teeth 2 bite the belt ribs 3. The dual fixing method of the belt ribs 3 and the sliding chain teeth 2 biting the belt ribs 3 significantly enhances the connection strength between the sliding chain teeth 2 and the sliding chain tape 1, so that the sliding chain can maintain good structural stability during frequent use.

[0039] The sliding chain arranged in the above manner not only enhances the connection strength between the sliding chain teeth 2 and the sliding chain tape 1 , but also improves the installation accuracy and structural stability.

[0040] In a feasible embodiment, the sliding chain tape 1 includes a left belt body 11 and a right belt body 12, and a belt rib 3 is provided on the side adjacent to the left belt body 11 and the right belt body 12. The left belt body 11 and the right belt body 12 are connected by a connecting belt body 14 on the side where the belt rib 3 is provided. The connecting belt body 14 is provided with a plurality of mounting holes 4 arranged in an array along the length direction of the sliding chain tape 1.

[0041] It should be noted that the sliding chain tape 1 is designed to include a left belt body 11 and a right belt body 12. This split design makes the sliding chain tape 1 more flexible, facilitating optimization of different parts and improving overall performance. The design of the connecting belt body 14 allows the left and right belt bodies 11, 12 to be securely connected together to form a complete sliding chain tape 1. Specifically, the left and right belt bodies 11, 12 can be processed separately and then connected together via the connecting belt body 14. This ensures the overall stability of the sliding chain tape 1, improving production efficiency and product quality.

[0042] Among them, by opening a plurality of mounting holes 4 arranged in an array along the length direction of the sliding chain tape 1 on the connecting belt body 14, the installation of the sliding chain teeth 2 is facilitated, so that the sliding chain teeth 2 can be more firmly fixed on the sliding chain tape 1, further improving the connection strength and reliability of the sliding chain, and ensuring that the sliding chain teeth 2 can be accurately aligned during installation, thereby improving the installation accuracy and thus improving the overall performance of the sliding chain.

[0043] Furthermore, a rib 3 is provided on the side adjacent to the left and right belt bodies 11 and 12. This reinforces the structural strength of the sliding chain tape 1, improving its durability and reliability. The rib 3 can withstand greater tension and pressure, thereby extending the service life of the sliding chain tape 1. In particular, the area around the mounting hole 4 effectively prevents deformation or damage to the sliding chain tape 1 due to external forces during frequent use. Furthermore, the rib 3 provides more stable support for the sliding chain teeth 2, reducing the risk of loosening or falling off due to external forces, further enhancing the overall stability of the sliding chain.

[0044] In a feasible embodiment, a sewing area 13 is provided on the side of the left belt body 11 and the right belt body 12 away from the rib 3, and a plurality of through holes 5 arranged in an array along the length direction of the sliding chain tape 1 are provided between the sewing area 13 and the rib 3.

[0045] As can be appreciated, the design of the sewing area 13 allows the left and right belt bodies 11 and 12 to be securely connected to other components (such as clothing, backpacks, etc.) via sewing on the side away from the ribs 3, thereby enhancing the overall connection stability of the sliding chain. This also allows the sliding chain to adapt to a variety of applications, such as clothing, backpacks, and tents, improving its versatility and applicability. The provision of through-holes 5 in the sewing area 13 effectively modifies the longitudinal elasticity and expansion / contraction rate of the sliding chain tape 1, improving its adaptability and flexibility. It also provides a certain degree of anti-arching effect, making the sliding chain tape 1 smoother and more comfortable during use.

[0046] On the basis of the above embodiment, the left belt body 11 and the belt rib 3, the through hole 5, and the sewing area 13 are integrally formed by weaving, the right belt body 12 and the belt rib 3, the through hole 5, and the sewing area 13 are integrally formed by weaving, and the connecting belt body 14 and the mounting hole 4 are integrally formed by weaving.

[0047] It should be noted that through textile one-piece molding, the left belt body 11 forms an integral structure with the belt ribs 3, through-holes 5, and sewing area 13; the right belt body 12 forms an integral structure with the belt ribs 3, through-holes 5, and sewing area 13; and the connecting belt body 14 forms an integral structure with the mounting hole 4, thereby enhancing the structural integrity and stability of the sliding chain tape 1. One-piece molding reduces the joints between different components, reduces the risk of structural damage caused by wear or loosening at the joints, and improves the durability of the sliding chain. It also makes the appearance of the sliding chain tape 1 smoother and more beautiful, improving the overall appearance quality. The one-piece molding process reduces multiple steps in the production process, improves production efficiency, and reduces production costs.

[0048] More importantly, the connecting belt body 14 and the mounting hole 4 are integrally formed through textile weaving, while the through hole 5 and the corresponding left and right belt bodies 11 and 12 are integrally formed through textile weaving. This avoids the need for additional punching, thereby reducing the equipment, energy, and labor costs required for punching, lowering overall production costs. It also avoids structural damage to the fabric belt that could be caused by punching, maintaining the overall strength and durability of the fabric belt. Furthermore, this integral molding technology simplifies the production process, making it more continuous and automated, and contributing to large-scale, efficient production. Because the mounting hole 4 and the ribs 3 are integrally formed with the fabric belt, this design enhances the structural strength of the sliding chain fabric belt 1, making the chain more stable and reliable, and improving the product's load-bearing capacity.

[0049] Furthermore, the left belt body 11, the right belt body 12, and the connecting belt body 14 are integrally formed by weaving.

[0050] In other words, through textile one-piece molding, the left belt body 11, the right belt body 12, and the connecting belt body 14 form an integral structure, significantly enhancing the structural integrity and stability of the sliding chain tape 1. This design enables the sliding chain to maintain good structural stability during use, reducing the risk of deformation or damage due to external forces. One-piece molding reduces the joints between different components, reduces the risk of structural damage due to wear or loosening at the joints, and improves the durability of the sliding chain. The one-piece molding process reduces multiple steps in the production process, simplifies the production process, and improves production efficiency. One-piece molding makes the appearance of the sliding chain tape 1 smoother and more beautiful, reduces appearance defects caused by uneven seams, and improves the overall appearance quality of the product.

[0051] In the above case, the left belt body 11, the right belt body 12, the connecting belt body 14, the mounting hole 4 and the through hole 5 are all formed by interweaving a plurality of warp threads and weft threads.

[0052] It is understood that the interweaving of the warp and weft threads provides a sturdy structure that enables the sliding chain tape 1 to withstand greater tension and pressure, thereby enhancing the overall durability and reliability. By adjusting the density and interweaving pattern of the warp and weft threads, the elasticity and scalability of the sliding chain tape 1 can be controlled, making it better adapted to different usage conditions and environments. The interweaving of the warp and weft threads allows for complex patterns and structural designs, such as the shape, size, and position of the mounting holes 4 and through holes 5, to meet specific functional requirements. The use of textile technology allows for the efficient production of the sliding chain tape 1, as the interweaving of the warp and weft threads can be quickly completed using automated looms, thereby improving production efficiency and reducing costs.

[0053] Furthermore, both the warp and the weft are yarns.

[0054] It should be noted that the use of yarn provides greater flexibility, and yarns of different materials, thicknesses and properties can be selected as needed to adapt to different application scenarios and performance requirements. Yarns are usually lighter than metal wires or other hard materials, which helps to reduce the overall weight of the sliding chain tape 1, making it more suitable for products such as clothing and luggage where weight is a consideration. Yarn materials are usually soft and more comfortable when in contact with the skin. The structure formed by the interweaving of yarns naturally has good air permeability, which helps to improve the comfort of wearing or using, especially in warm or humid environments. Yarns are usually lower in cost than special materials, which helps to reduce production costs. Yarns are easy to process using standard textile machinery, which helps to simplify the production process and improve production efficiency.

[0055] Please refer to Figure 4 The fabric structure of the left belt body 11 and the right belt body 12 is a 1-upper-1-lower plain weave.

[0056] As can be understood, the warp and weft yarns in a 1-over-1-under plain weave interweave every other yarn, resulting in the most frequent yarn interweaving and the greatest buckling. This combination is the strongest and reduces lateral displacement of the ribs 3. The left and right belt bodies 11, 12, constructed using a 1-over-1-under plain weave, provide excellent structural stability, allowing them to withstand certain tension and pressure without deformation. The plain weave is relatively simple, amenable to large-scale production, and highly efficient, thus reducing manufacturing costs.

[0057] On the basis of the above embodiment, the fabric structure of the connecting belt body 14 is a 2-up 2-down twill structure.

[0058] It should be noted that the connecting belt 14 between the ribs 3 utilizes a 2-up, 2-down warp-broken twill weave, resulting in a more stable and balanced structure, reducing the risk of deformation and balancing flexibility and strength. This 2-up, 2-down twill weave provides a certain degree of elasticity, allowing the connecting belt 14 to better recover its original shape after being subjected to stress, helping to maintain the shape and function of the sliding chain tape 1. The twill weave, through the interweaving of additional warp or weft yarns, provides greater strength than a plain weave. This makes the connecting belt 14 more durable and able to withstand greater tension and compression. The twill weave's compact structure also provides improved wear resistance.

[0059] In the above embodiment, the fabric structure of the sewing area 13 is a 2-up 2-down weft double plain structure.

[0060] It is understandable that the sewing area 13 adopts a 2-up 2-down weft-double plain weave. The floating length of the weft yarn in the weft-double plain weave is increased, making the fabric more extensible in the weft direction (transverse direction) and softer, which is conducive to the insertion of the sewing needle during sewing, and improves the smoothness and efficiency of sewing. Due to the increased extensibility in the weft direction, the shrinkage rate of the fabric during sewing is reduced, which helps to maintain the flatness and appearance quality of the sewing area 13 and reduce wrinkles and unevenness. The weft-double plain weave structure is relatively tight, which can improve the wear resistance and tear resistance of the sewing area 13, making the sewing line more solid and extending the service life of the product. The longer floating length of the weft yarn increases the softness of the fabric, making the sliding chain tape 1 more comfortable when in contact with the skin or other materials, and improving the comfort of wearing or using.

[0061] As a preferred embodiment, the warp threads of the mounting hole 4 and the through hole 5 include: a ground warp group A 6 and a twisted warp group B 7, the ground warp group A 6 includes two first warp yarns, the twisted warp group B 7 includes two second warp yarns, the two second warp yarns are located between the two first warp yarns, and the second warp yarns are twisted with the adjacent first warp yarns every 4 wefts to form the mounting hole 4 and the through hole 5.

[0062] It should be noted that the connecting tape can be formed in a variety of ways, such as by threading directly through the ribs 3 of the left and right belt bodies 11, 12 to connect them together, or by using a perforated strip of tape with sutures, or by other structures or processes that can be used in conjunction with the left and right belt bodies 11, 12 (such as sewing, gluing, or weaving in). Preferably, the left and right belt bodies 11, 12 are connected by threading through the ribs 3 of the left and right belt bodies 11, 12, with the stitching being dense in some areas to form a strong, secure connection 14, and the stitching being widely spaced in some areas to form the mounting holes 4. This method of connecting the left and right belt bodies 11, 12 and forming the mounting holes 4 makes production simpler and more convenient.

[0063] In this embodiment, holes are preferably formed, i.e., the mounting holes 4 and through holes 5, by a yarn weaving method. The lateral width of the mounting hole 4 is determined by the initial distance between the hank warp group B 7 and the adjacent ground warp group A 6. This initial distance is increased by adjusting the reeding method. During reeding, the spacing between the hank warp group B 7 and the adjacent ground warp group A 6 is increased. Ground warp group A 1 is inserted into reed dent 1, and hank warp group B 7 is inserted into reed dent 3 (with one tooth left empty in between). When the hank warp group B 7 is twisted around the ground warp group A 1, the mounting hole 4 expands laterally due to the larger horizontal spacing. The larger the spacing, the wider the mounting hole 4 formed after twisting.

[0064] The weaving method for through hole 5 simply replaces the ribs 3 with ground warp group A 6 yarns. Specifically, the warp yarns are divided into ground warp group A 6 and thong warp group B 7. Ground warp group A 6 is threaded into a standard heald frame, while thong warp group B 7 is threaded into a thong heald frame. When weft 1 is woven, the thong heald is raised to its highest point, and the ground warp group A 1 is simultaneously raised. Thong warp group B 7 rotates 180° around ground warp group A 1, forming the edge of through hole 5. When weft 2 is woven, the ground warp group A 2 is raised, and the weft yarn passes through the fixed thong. When weft 3 is woven, the ground warp group A 1 is raised, and thong warp group B 7 is partially relaxed, expanding the hole. When weft 4 is woven, the ground warp group A 2 is raised, and thong warp group B 7 is partially relaxed, forming the bottom of through hole 5. This cycle completes, forming an elliptical hole every four picks. The higher the thong heald is raised, the greater the twist angle of the thong, and the narrower and longer through hole 5 becomes. The size of the hole is adjusted by controlling the weft density.

[0065] By precisely controlling the kinking points and frequency (twisting every four picks) of the second warp yarns (hank warp group B 7) with the first warp yarns (ground warp group A 6), the shape and size of the mounting holes 4 and through-holes 5 can be precisely controlled to meet specific design and functional requirements. The regular kinking pattern helps create evenly distributed holes. The specific configuration of the hank warp group B 7 and ground warp group A 6 provides additional structural stability, helping to maintain the shape of the holes and prevent deformation during use. By adjusting the kinking frequency and position of the second warp yarns with the first warp yarns, holes of varying shapes and sizes can be flexibly designed to suit different application scenarios.

[0066] The shape of the mounting hole 4 can be any shape, such as circular, square, polygonal, irregular, etc., preferably rectangular, and can be directly woven by weaving, which makes the tooth installation more convenient and faster. The shape of the through hole 5 can also be any shape, preferably rectangular, and the effect and weaving principle are similar to those of the mounting hole 4 described above.

[0067] In the above case, the ratio of the width of the mounting hole 4 to the width of the sliding chain teeth 2 is 1 / 5-4 / 5.

[0068] It is understood that the ratio of the width of the mounting hole 4 to the width of the sprocket teeth 2 is 1 / 5-4 / 5. This range ensures the strength of the sprocket teeth 2 on the fabric tape, effectively engages the ribs 3, and keeps the sprocket teeth 2 from being too large. If the ratio of the width of the mounting hole 4 to the width of the sprocket teeth 2 is less than 1 / 5, the mounting hole 4 may be too small, affecting the strength of the sprocket teeth 2 on the fabric tape. If the ratio of the width of the mounting hole 4 to the width of the sprocket teeth 2 is greater than 4 / 5, the spacing between the mounting holes 4 is too large, and either the sprocket teeth 2 cannot effectively engage the ribs 3, or the sprocket teeth 2 may be too large, affecting normal use and aesthetics.

[0069] Maintaining an appropriate ratio between the width of the mounting hole 4 and the width of the chain tooth 2 ensures a strong connection between the chain tooth 2 and the fabric tape, helping to prevent the chain tooth 2 from falling off the fabric tape when stressed, thereby improving the overall durability of the chain. A properly wide mounting hole 4 allows the chain tooth 2 to effectively engage the rib 3, thereby improving the stability and reliability of the chain. Limiting the ratio of the mounting hole 4 to the width of the chain tooth 2 prevents the chain tooth 2 from being too large, which helps maintain the compactness and aesthetics of the chain while preventing the chain tooth 2 from being too large and affecting its proper operation.

[0070] In the above embodiment, the ratio of the vertical distance between the through hole 5 on the left belt body 11 and the rib 3 on the left belt body 11 to the width of the left belt body 11 is 1 / 4-2 / 3, and the ratio of the vertical distance between the through hole 5 on the right belt body 12 and the rib 3 on the right belt body 12 to the width of the right belt body 12 is 1 / 4-2 / 3.

[0071] It should be noted that within this range, the through holes 5 do not affect the installation of the sliding chain teeth 2 while also ensuring the longitudinal elasticity and contraction of the belt body. By controlling the vertical distance between the through holes 5 and the ribs 3, the stability of the sliding chain teeth 2 during installation can be ensured, and the problem of the sliding chain teeth 2 being displaced or not being firmly installed due to the presence of the through holes 5 can be avoided. The presence of the through holes 5 will affect the contractility of the belt body. The appropriate vertical distance ensures the longitudinal elasticity of the belt body, allowing the sliding chain fabric tape 1 to adapt to different tensions and pressures, improving its durability and reliability. Within the ratio range of 1 / 4-2 / 3, the sliding chain fabric tape 1 can better adapt to different application scenarios and needs, whether in environments with high strength requirements or in situations that require flexible adjustment.

[0072] Among them, the above-mentioned sliding chain tape 1 can be applied to the sub-chain of the sliding chain, and can also be applied to the main chain. Connecting columns are formed on the teeth of the sub-chain or the main chain. The connecting columns pass through the mounting holes 4 to connect the inner and outer parts of the teeth. The tooth offset is reduced by the connecting columns and the mounting holes 4, and the connection strength and stability of the teeth on the tape are increased.

[0073] In the above embodiment, one sliding chain tooth 2 is injection-molded into at least two of the mounting holes 4 .

[0074] It should be noted that the sliding chain teeth 2 preferably pass through 2-4 mounting holes 4 at the same time, so that the sliding chain teeth 2 can maintain a sufficiently strong connection with the cloth belt, while the connection holes will not be too dense or too wide to affect the cloth belt production and the injection molding installation of the sliding chain teeth 2.

[0075] Furthermore, stops 8 are provided at both ends of the sliding chain. The stops 8 are wider than the width of the sliding chain teeth 2. When the sub-chain teeth 21 are pulled into contact with the stops 8, the stops 8 will block the sub-chain teeth 21, preventing the sub-chain from separating from the main chain. In addition to the mounting holes 4 and the ribs 3 serving as mounting structures for the stops 8, the through-holes 5 in the middle of the belt body can also serve as mounting holes 4 for the stops 8. That is, both sides of the stops 8 can extend to the through-holes 5, and corresponding connecting columns are formed on the stops 8 to pass through the through-holes 5 to connect the parts of the stops 8 located on the inner and outer surfaces of the belt body. In addition to changing the longitudinal elasticity and expansion ratio of the sliding chain tape 1 to prevent arching, the through-holes 5 can also enhance the connection strength between the stops 8 and the belt body when required. Among them, the mounting holes 4 and the ribs 3 can not only serve as the mounting structure of the sliding chain teeth 2 and the stopper 8, but other injection-molded structures on the sliding chain can also use the mounting holes 4 and the ribs 3 as mounting structures to achieve installation and fixation on the cloth belt, with a wider range of adaptability.

[0076] It should be noted that, in order to ensure the meshing of the teeth and the limitation of the tape, the teeth of conventional zippers or zippers can usually only be formed on the side edges of the tape, which results in the conventional sliding chain or zipper having to be matched with tapes on both sides, which makes the overall sliding chain wider. The sliding chain teeth 2 of the present application are formed in the mounting hole 4 in the middle of the tape, and the matching structure of the sub-chain and the main chain is arranged perpendicular to the thickness direction of the tape. Therefore, the width of the sliding chain tape 1 can be the width of the tape on one side of the conventional zipper tape. The overall width of the sliding chain is smaller, and it is more compact and concealed after being sewn on clothing. At the same time, when the sliding chain teeth 2 are formed, there is no need to place the two tapes on both sides and then injection-mold the teeth like a conventional sliding chain. It is only necessary to place the sliding chain tape 1 and then injection-mold the teeth. There is no need to align the tapes on both sides, place them for stabilization, etc., making production more convenient and efficient. The sliding chain teeth 2 are passed through the mounting hole 4 by injection molding and are simultaneously molded on the inner and outer surfaces of the tape, achieving a strong connection of the sliding chain teeth 2 on the tape. At the same time, the left and right sides of the sliding chain teeth 2 can respectively engage with the belt ribs 3 of the left belt body 11 and the right belt body 12, further increasing the strength and stability of the sliding chain teeth 2 on the cloth belt.

[0077] Please refer to Figure 5The sliding chain teeth 2 include sub-chain teeth 21 and mother chain teeth 22. A sliding chain typically includes a mother chain and a sub-chain that can slide within the mother chain. The sub-chain includes a sub-chain tape and sub-chain teeth 21 disposed on the sub-chain tape. The sub-chain teeth 21 include a first base 211, a sliding portion 212, and a first connecting post 213 for connecting the first base 211 and the sliding portion 212. The mother chain includes a mother chain tape and mother chain teeth 22 disposed on the mother chain tape. The mother chain teeth 22 include a second base 221, a meshing portion 222, and a second connecting post 223 for connecting the second base 221 and the meshing portion 222. The meshing portion 222 is provided with a slideway 2221 for the sliding portion 212 to slide. The sliding portion 212 slides along the slideway 2221 of the mother chain teeth 22, enabling the sub-chain to slide on the mother chain. The slideway 2221 provides a precise sliding path for the sliding portion 212, ensuring precise alignment between the sub-chain teeth 21 and the main chain teeth 22 during engagement and disengagement. This reduces jamming and wear caused by misalignment, significantly improving the chain's meshing stability. The first connecting post 213 of the sub-chain tooth 21 and the second connecting post 223 of the main chain tooth 22 connect the base and the sliding or meshing portion, respectively, enhancing the overall strength and rigidity of the teeth. During use, the teeth are better able to withstand external forces, reducing the risk of deformation and damage, and extending the service life of the chain.

[0078] It should be noted that the sliding chain teeth 2 preferably pass through 2-4 mounting holes 4 simultaneously, so that the sliding chain teeth 2 can maintain a sufficiently strong connection with the tape while preventing the connection holes from being too dense or too wide, which would affect tape production and the injection molding installation of the sliding chain teeth 2. In other words, a sub-chain tooth 21 may have multiple first connecting posts 213, and the multiple first connecting posts 213 are distributed in multiple mounting holes 4. Similarly, a mother chain tooth 22 may have multiple second connecting posts 223, and the multiple second connecting posts 223 are distributed in multiple mounting holes 4.

[0079] In summary, the sliding chain provided by the present invention has a mounting hole 4 and a rib 3 formed in the middle of the sliding chain tape 1, and the mounting hole 4 and the rib 3 are used to improve the connection strength between the sliding chain teeth 2 and the tape. The through hole 5 in the middle of the left belt body 11 and the right belt body 12 plays a role in changing the longitudinal elasticity and expansion rate of the sliding chain tape 1 to prevent arching. The overall width of the tape is narrower than that of a conventional sliding chain. Moreover, the rib 3, the mounting hole 4, the through hole 5 and the sliding chain tape 1 are formed at the same time by a textile integrated molding method, without the need for additional punching steps, reducing the production process, reducing the production cost and process complexity, and improving the overall strength and durability of the sliding chain tape 1.
