Description

Technical Field

[0001] This utility model relates to the field of slip chain technology, and more specifically, to a slip chain belt and a slip chain. Background Technology

[0002] Slip chains, as commonly used connecting components in clothing and other fields, play an important role in people's daily lives.

[0003] In existing technologies, to enhance the stability and strength of the teeth on the fabric tape and reduce tooth installation misalignment, positioning through holes are typically formed directly on the fabric tape. These through holes are used to fix the teeth to the tape, ensuring uniform tooth distribution and stable installation. However, the aforementioned existing technologies have significant drawbacks. During sewing, the fabric tape shrinks, causing arching and deformation in the tooth area, affecting the garment's aesthetics.

[0004] In summary, how to avoid the problem of fabric tape shrinkage during sewing causing arching and deformation in the chain teeth area is a problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0005] In view of this, the purpose of this utility model is to provide a sliding chain belt and sliding chain that effectively changes the longitudinal elasticity and elongation of the sliding chain belt, thereby playing a role in preventing arching.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A sliding chain belt includes a pair of belt bodies arranged opposite each other. A reinforcing rib is arranged on the side of the belt bodies closest to each other. The belt bodies are provided with a chain tooth area and a sewing area in sequence along the width direction. The area close to the reinforcing rib is the chain tooth area. A plurality of mounting holes are provided in the chain tooth area along the length direction of the belt body. A female chain tooth connects the reinforcing rib of the pair of belt bodies and is installed in the chain tooth area. Each female chain tooth covers at least one of the mounting holes.

[0008] Preferably, at least one side of the sewing area of ​​a pair of belt bodies is provided with a plurality of through holes arranged in an array along the length direction of the belt body.

[0009] Preferably, the chain teeth formed by the multiple parent chain teeth are provided with anti-slip teeth at both ends, and the top of the anti-slip teeth is provided with a protrusion.

[0010] Preferably, the mounting hole and the through hole are specifically round holes, square holes, polygonal holes, irregular holes or elongated rectangular holes.

[0011] Preferably, the main body of the mother chain teeth is provided with a sliding channel.

[0012] Preferably, the ratio of the distance between the mounting hole and the reinforcing rib to the overall width of the belt body is in the range of 1 / 4 to 2 / 3.

[0013] Preferably, the fabric weave in the chain tooth area is a 2 / 2 warp-broken twill weave.

[0014] Preferably, the fabric weave of the sewing area is a 2 / 2 weft-weighted plain weave.

[0015] Preferably, a single mounting hole and / or a single through hole is formed by a strand around the ground.

[0016] A sliding chain includes a mother chain, the mother chain including mother chain teeth disposed on the chain tooth area of ​​the sliding chain belt, the mother chain teeth being injection molded in the chain tooth area, and the injection molding material penetrating the chain tooth area to form an anchor post.

[0017] The sliding chain belt provided by this utility model has several through holes arranged in an array along the length of the belt body in the middle section. The through holes effectively change the longitudinal elasticity and elongation of the sliding chain belt, and play a role in preventing arching in the chain tooth area.

[0018] The further solutions provided in this application can also achieve at least one of the following beneficial technical effects:

[0019] The use of a 2 / 2 warp-broken twill weave in the chain tooth area makes the structure of this area more stable and balanced, reduces the risk of deformation, and balances softness and strength.

[0020] The fabric structure in the sewing area adopts a 2 / 2 weft-weighted plain weave. Due to the increased weft float (2 consecutive floats), the fabric has better and softer stretch in the weft direction (lateral direction), which is conducive to the entry of sewing needles and can reduce sewing shrinkage.

[0021] The ratio of the distance between the mounting hole and the reinforcing rib to the overall width of the belt is optimized to be within the range of 1 / 4 to 2 / 3, so that the through hole does not affect the installation of the main chain teeth while ensuring the longitudinal elasticity and shrinkage of the belt.

[0033] The core of this utility model is to provide a sliding chain belt.

[0034] Another core aspect of this utility model is to provide a sliding chain, including a mother chain, which is disposed on the aforementioned sliding chain belt.

[0035] Please refer to Figure 1 .

[0036] The sliding chain belt provided by this utility model includes a pair of belt bodies 1 arranged opposite each other. The belt bodies 1 are provided with a reinforcing rib 2 on the side closer to the other side. The belt body 1 is provided with a chain tooth area 8 and a sewing area 9 in sequence along the width direction. The area close to the reinforcing rib 2 is the chain tooth area 8. A plurality of mounting holes 3 are provided in the chain tooth area 8 along the length direction of the belt body 1. The female chain tooth 5 connects the reinforcing rib 2 of the pair of belt bodies 1 and is installed in the chain tooth area 8. Each female chain tooth 5 covers at least one mounting hole 3.

[0037] Specifically, there are two belt bodies 1 arranged opposite each other on the left and right. Each belt body 1 has a rib 2 on the side where they are close to each other. The area where the ribs 2 face each other is the inner side, and the area where the ribs 2 face away is the outer side. Several mounting holes 3 are arranged in an array along the length of the belt body 1 outside the ribs 2 and at the edge of the belt body 1. The mounting holes 3 and the ribs 2 are used to install and fix the teeth 5 of the mother chain, which effectively increases the stability of the teeth 5 of the mother chain on the belt body 1.

[0038] A pair of belt bodies 1 are provided with a chain tooth area 8 and a sewing area 9 along the width direction. The chain tooth area 8 is the side closer to the belt rib 2, while the sewing area 9 is the side away from the belt rib 2. The belt rib 2 and the mounting hole 3 are located within the chain tooth area, which effectively realizes functional zoning, thereby enabling the belt body 1 to take into account both rigidity and flexibility.

[0039] A pair of belt bodies 1 have a number of through holes 4 arranged in an array along the length of the belt body 1 at least one side of the sewing area 9.

[0040] Specifically, the belt body 1 is located outside the rib 2 and in the middle section of the belt body 1, with a number of through holes 4 arranged in an array along the length of the belt body 1. The array of through holes is provided on at least one of the belt bodies 1. The through holes 4 can be arranged in parallel with the mounting holes 3. At the same time, the arrangement of the through holes 4 can divide the belt body 1 into a chain tooth area 8 and a sewing area 9. The rib 2 and the mounting holes 3 are the chain tooth area, and the area of ​​the belt body 1 outside the through holes 4 is the sewing area 9. Thus, by setting these through holes 4, the longitudinal elasticity and elongation of the slip chain belt can be effectively changed, thereby playing a role in preventing arching.

[0041] The aforementioned slip chain belt has several through holes arranged in an array along the length of the belt body in the middle section. These through holes effectively change the longitudinal elasticity and elongation of the slip chain belt, thus preventing arching in the chain tooth area.

[0042] The sliding chain belt provided by this utility model will be described in more detail below with reference to the accompanying drawings and specific embodiments.

[0043] In one specific implementation, such as Figure 1 and Figure 2The mounting hole 3 and the through hole 4 are specifically round holes, square holes, polygonal holes, irregular holes or long rectangular holes.

[0044] Specifically, the shape of the mounting hole 3 and the through hole can be any shape, such as a round hole, a square hole, a polygonal hole, an irregular hole, or a long rectangular hole. In this application, it is preferred to be a long rectangular hole. This kind of long rectangular hole can be directly made by weaving, which achieves the purpose of tooth installation while making production more convenient and faster.

[0045] It should be noted that the sizes of mounting holes 3 and through holes 4 in the figure are not their actual sizes, but are enlarged to show the structural features.

[0046] Based on any of the above embodiments, refer to Figure 5 The fabric structure of the chain tooth area 8 is a 2 / 2 warp-broken twill weave.

[0047] Specifically, the strip between the rib and the mounting hole adopts a 2 / 2 warp-broken twill weave (i.e., 2 upper and 2 lower warp-broken twill weave), which makes the structure of this area more stable and balanced, reduces the risk of deformation, and balances flexibility and strength.

[0048] Furthermore, a single mounting hole 3 and / or a single through hole 4 is formed by twisting the reed wire around the ground wire. Taking mounting hole 3 as an example, the lateral width of mounting hole 3 is determined by the initial distance between the twisted wire B and the adjacent ground wire A. The initial distance is increased by adjusting the reed threading method. During reed threading, the spacing between the number of reed teeth of the twisted wire B and the adjacent ground wire A is increased. The ground wire A1 is threaded into reed tooth 1, and the twisted wire B is threaded into reed tooth 3 (with one tooth left empty in the middle). When the twisted wire B twists around the ground wire A1, due to the large horizontal spacing, the mounting hole expands laterally. The larger the spacing, the wider the mounting hole formed after twisting.

[0049] The method for manufacturing the hole array of the above-mentioned mounting hole 3 specifically includes the following steps:

[0050] S1. Warp grouping: Ground warp (Group A) goes through ordinary heald frames, and twisted warp (Group B) goes through twisted heald frames;

[0051] S2, Hole Formation Cycle (4 wefts / hole):

[0052] Latitude 1: Raise the heddle to the highest point + raise the ground meridian A1 → rotate the heddle B around A1 by 180° (forming the hole edge);

[0053] Weft 2: Ground warp A2 lifting → weft yarn fixing knot point;

[0054] Latitude 3: Earth meridian A1 is raised + twisting meridian B part is relaxed → hole expansion;

[0055] Latitude 4: Earth Meridian A2 lifting + Twisting Meridian B loosening → Hole shaping;

[0056] S3, Aperture Control:

[0057] Increased heddle lifting height → increased warp twist angle → narrower and longer hole;

[0058] Increased weft density leads to decreased hole size.

[0059] Specifically, in step S1, regarding the grouping requirements, the ground warp (Group A) passes through a standard heald frame, responsible for the basic structure, while the twill warp (Group B) passes through a dedicated hole in the twill heald frame. Furthermore, the warp density ratio of the ground warp (Group A) to the twill warp (Group B) is approximately 3:1 to ensure the stability of the holes. This step S1, by separating the functional yarns, prevents deformation of the ground warp during twisting, maintaining the balance of the 2 / 2 warp-broken twill weave in the chain tooth area.

[0060] In step S2, the rotation angle in weft 1 forces the release of warp tension, forming the initial shape of the hole. The weft yarn intervenes to fix the knot, and the rotation angle must be ≥150° to close the hole edge and avoid burrs. In weft 2, the weft yarn can be high-strength polyester yarn with a tension ≥50cN to prevent the knot from loosening and ensure that the hole does not deform during extension. In weft 3, the warp tension is relaxed to reduce the warp tension, and the weft yarn thrust promotes the increase of the hole width. The expansion rate is controlled by the initial spacing of the warp. In weft 4, the loom temperature is maintained at 60-80°C (heat setting process) to ensure that the hole does not deform during subsequent injection molding.

[0061] In step S3, the hole length is increased according to the increase in height, which can effectively improve the tensile strength; by adjusting the weft density, the shrinkage rate of the hole can be adjusted. High density can be used to generate holes in the sewing area, and low density can be used to generate holes in the chain tooth area.

[0062] refer to Figure 6 It should be noted that the through hole 4 and the outer edge of the belt body 1 (i.e., the sewing area 9) also adopt a 2 / 2 warp-broken twill weave (i.e., 2 upper and 2 lower warp-broken twill weave), which effectively reduces the deformation of the through hole 4. The shape of the through hole 4 can also be any shape, preferably a long rectangular hole, and the effect and weaving principle are similar to those of the mounting hole 3 mentioned above.

[0063] Based on any of the above embodiments, the fabric structure of the sewing area 9 is a 2 / 2 weft-ply plain weave.

[0064] Specifically, sewing area 9 adopts a 2 / 2 weft-flat weave, i.e. (2 up 2 down weft-flat weave). Due to the increased weft float (2 consecutive floats), the fabric has better and softer stretch in the weft direction (lateral direction), which is conducive to the insertion of sewing needles and thus reduces the sewing shrinkage rate.

[0065] In one specific embodiment provided in this application, the reinforcing ribs 2 of the two belt bodies 1 are connected by a sewing thread.

[0066] Specifically, the connecting components can take many forms, such as the stitches passing directly through the reinforcing ribs 2 of the left and right belt bodies 1 to connect the left and right belt bodies 1 together, or connecting the left and right belt bodies 1 by a perforated strip and stitches, or other structures or processes that can work with the belt bodies 1 (such as sewing, gluing, weaving, etc.) to connect the two belt bodies 1 together.

[0067] The preferred design connects the left and right belt bodies 1 together via stitches passing through the reinforcing ribs 2. In some areas, the stitches are denser to form a strong, high-strength connection, while in other areas the stitches are spaced further apart, forming the aforementioned mounting holes 3. This method of connecting the belt bodies 1 and forming the mounting holes 3 simplifies production. The left and right belt bodies 1 can be produced as normal fabric belts, and the connection between them can be achieved simply through sewing equipment. Production is also more flexible; manufacturers can modify the sliding chain by selecting appropriate belt bodies 1, stitches, or adjusting the spacing between the belt bodies and the mounting holes as needed.

[0068] Based on any of the above embodiments, the ratio of the distance between the mounting hole 3 and the rib 2 to the overall width of the belt 1 is in the range of 1 / 4 to 2 / 3.

[0069] Specifically, the distance between the mounting hole 3 and the reinforcing rib 2 is preferably 1 / 4 to 2 / 3 of the overall width of the belt body 1. Within this range, the through hole 4 does not affect the installation of the main chain teeth 5 while ensuring the longitudinal elasticity and shrinkage of the belt body 1.

[0070] The slip chain belt provided in this application improves the tensile strength by more than 40% through double-hole anchoring of the chain teeth and material interlocking; reduces the seam shrinkage rate by 30% through the high-rigidity isolation strip of the outer hole; improves the sewing yield by 25% through the optimization of the extensibility of the weft-overlap flat weave of the fabric edge; and improves the flatness of the chain teeth and eliminates arching through the stress isolation design.

[0071] Please refer to Figure 1

[0072] The slip chain provided in this application includes a main chain and a sub-chain. The main chain includes main chain teeth 5 disposed in the chain tooth area of ​​the slip chain belt. The main chain teeth 5 are injection molded in the chain tooth area 8, and the injection molding material penetrates the chain tooth area 8 and forms an anchor post. At the same time, the main chain teeth 5 cover the reinforcing rib 2, further increasing the strength and stability of the main chain teeth 5 on the slip chain belt.

[0073] like Figure 1-4As shown, the chain teeth 5 of the main chain are provided with anti-slip teeth 7 at both ends. The top of the anti-slip teeth 7 is provided with a protrusion. The main body of the main chain teeth 5 is provided with a sliding channel 6, which facilitates the back-and-forth sliding of the sub-chain to achieve a sliding effect. At the same time, when the sub-chain teeth are pulled to contact the anti-slip teeth 7, the anti-slip teeth 7 will block the sub-chain teeth and prevent the sub-chain from detaching from the main chain. The sliding belt is provided with ribs 2 next to the mounting holes 3, located on the left and right edges of the belt, for fixing with the sliding belt teeth (main chain teeth 5, anti-slip teeth 7) to prevent the teeth from falling out.

[0074] It should be noted that the mounting hole 3 and the rib 2 can not only serve as the mounting structure for the main chain teeth 5 and the anti-slip teeth 7, but also for other injection-molded structures on the slip chain, making them suitable for mounting and fixing on the fabric belt, thus expanding the range of applications.

[0075] Based on any of the above embodiments, refer to Figure 1 The teeth 5 of the mother chain at least completely cover one mounting hole 3, thereby forming a complete anchor pile connection between the positive and negative chain teeth.

[0076] This application also provides a garment including the aforementioned slip chain. The other structures of the garment are the same as those in the prior art, and will not be described in detail here.

[0077] The various embodiments in this specification are described in a progressive manner, with each embodiment focusing on the differences from other embodiments. The same or similar parts between the various embodiments can be referred to each other.
