[0026] In order to further explain the technical means and effects adopted by the present invention to achieve the predetermined purpose of the utility model, the specific implementation method, structure, characteristics and effects of the present invention are described in detail below in combination with the accompanying drawings and preferred embodiments.

[0027] Embodiment 1

[0028] Please refer to Figure 1 to Figure 2 As shown, it shows the specific structure of the preferred embodiment 1 of the utility model, which is a cloth connecting edge.

[0029] The wrapping portion 13 and the inner rib 16 are bonded together to form a whole, and the first extension portion 14 and / or the second extension portion 15 overlap and then bond with the fabric 17. This design eliminates the need for a zipper and reduces manufacturing costs. After the elastic fabric connection edge is straightened, the first extension portion 14 and the second extension portion 15 are also straight, and the splicing edge of the fabric 17 is directly overlapped on the first extension portion 14 and / or the second extension portion 15, and then the fabric 17 and the fabric connection edge can be spliced ​​together by hot melting. Therefore, the fabric connection edge makes it easy to adjust the splicing edge, and the splicing of the fabric 17 is convenient, which is conducive to improving production efficiency.

[0030] The present application provides a fabric connecting edge, comprising a flexible connecting body 10, which is sticky after hot melting; after the connecting body 10 is hot melted to wrap the inner rib 16, a wrapping portion 13, a first extension portion 14, and a second extension portion 15 are formed on the connecting body 10, and the wrapping portion 13 is bonded to the inner rib 16; the first extension portion 14 and the second extension portion 15 extend from the wrapping portion 13 to the same side; wherein the inner rib 16 is an elastic rope or a spring. In this embodiment, the extension width of the first extension portion 14 and the second extension portion 15 is between 3-5 cm, and the width of the splicing edge of the fabric 17 can be equal to / slightly less than the extension width of the first extension portion 14 and the second extension portion 15. The splicing edge of the cloth 17 can be placed on any one of the first extension part 14 and the second extension part 15, or on the first extension part 14 and the second extension part 15 at the same time, and then the first extension part 14 and / or the second extension part 15 pass through the electric heating belt to heat-melt the splicing edge of the cloth 17 and the cloth connecting edge together, which has higher splicing efficiency. At the same time, after the elastic cloth connecting edge is straightened, the first extension part 14 and the second extension part 15 are also straight, which is convenient for workers to place the splicing edge of the cloth 17 on the first extension part 14 and / or the second extension part 15. The splicing edge adjustment is very convenient, which is conducive to improving production efficiency. The processing technology of the cloth connecting edge is as follows: 1. Put the connector 10 into the mold, and then close the mold for a part of the stroke. 2. Insert the inner rib 16 into the mold, and then the mold is electrically heated so that the wrapping part 13 wraps the inner rib 16. Among them, the first extension part 14 and the second extension part 15 can be partially bonded together when the mold is heated, or not bonded together at all, which is convenient for subsequent splicing of the cloth 17.

[0031] Preferably, the connector 10 includes the hot melt adhesive layer 11 and the toughness layer 12 bonded together. The hot melt adhesive layer 11 will melt after being heated, so that the inner side of the connector 10 has stickiness, and the toughness layer 12 has good toughness and has tear and puncture resistance. Therefore, the connector 10 has both toughness and stickiness. In this embodiment, the hot melt temperature of the elastic rope body is higher than the hot melt temperature of the connector 10. When the connector 10 is heated, when the hot melt adhesive layer 11 melts, the elastic rope body will not melt. This design can protect the elastic rope body and prevent the elastic rope body from being heated and its performance deteriorating.

[0032] Preferably, the toughness layer 12 is one of polyvinyl chloride fiber, polyethylene fiber, polypropylene fiber, tiger cotton, rayon, polyester, nylon, acrylic fiber, chlorofiber, vinylon, and cotton cloth. The toughness layer 12 in this embodiment is polyvinyl chloride fiber, which has good warmth retention, insulation, high chemical stability, and good wear resistance.

[0033] Preferably, the hot melt adhesive layer 11 is one of PVC adhesive film, EVA hot melt adhesive, PO hot melt adhesive, PUR hot melt adhesive, PA hot melt adhesive, TPU hot melt adhesive, and PE hot melt adhesive. The hot melt adhesive layer 11 in this embodiment is a PVC adhesive film, which can be made sticky by heating, so that the connector 10 can be hot-melted to wrap the inner rib 16 and bond the fabric 17.

[0034] Preferably, the elastic rope is one of nylon rope, glass fiber rope, synthetic fiber rope, plastic rope, steel wire rope and rubber rope. The elastic rope of this embodiment is a plastic rope, which has a certain elasticity and can straighten itself, making it convenient for workers to align the splicing edge of the cloth 17 with the first extension part 14 and / or the second extension part 15, thereby improving the production efficiency of workers.

[0035] When the inner rib 16 is a spring, the spring is cylindrical or strip-shaped. This shape is conducive to the connector 10 to wrap the inner rib 16 by hot melting, and the wrapping is more firm.

[0036] Embodiment 2

[0037] Please refer to Figures 6-7, the present application provides a fabric 17, including the fabric connection edge; the width W1 of the first extension part 14 is greater than the width W2 of the second extension part 15; the fabric 17 is heat-melted and bonded to the first extension part 14 and / or the second extension part 15. Of course, the first extension part 14 and the second extension part 15 can also be of equal width or unequal width. When the first extension part 14 and the second extension part 15 are of equal width, the first extension part 14 and the second extension part 15 clamp the splicing edge of the fabric 17, and at the same time fuse and bond with the splicing edge of the fabric 17. For example, the first extension part 14 and the second extension part 15 are of unequal length. For example, when the width of the first extension part 14 is greater than the width of the second extension part 15, the splicing edge of the fabric 17 directly overlaps the first extension part 14 and is heat-melted and bonded to the first extension part 14. When the cloth 17 is fixed, the fixing seat 18 is fixed at a preset position (such as a wall or a wooden board), and the cloth connecting edge on the cloth 17 is inserted into the mounting groove 19 of the fixing seat 18, which is very convenient.

[0038] Preferably, the fabric 17 is one of mesh, plastic, canvas, cotton, and non-woven fabric.

[0039] In summary, the design focus of the present invention is that the fabric connecting edge can replace the zipper, has a simple structure, is easy to manufacture, reduces the production cost of the fabric 17, and also improves the production efficiency of workers.
