Description

Technical Field

[0001] This utility model relates to the field of textile technology, and in particular to a trampoline cloth with an edge-reinforced structure. Background Technology

[0002] Trampoline fabric, also known as trampoline cloth, is the load-bearing component of a trampoline or jumping bed, mainly used to withstand the impact and tensile force when the user jumps. Trampoline fabrics are mostly made of high-strength synthetic fiber fabrics, commonly including polyester fiber, nylon, or a blend of both. They are made through woven processes such as plain weave and twill weave. Currently, the edges of trampoline fabrics often use single-layer folded seams to sew and fix multiple straps, thus providing connection points for the springs connecting the trampoline fabric to the trampoline frame. The single-layer fold relies solely on a single layer of fabric and seam to bear the tension of the straps, concentrating the stress at the needle holes and folded edges. After long-term stretching, they are prone to cracking from the needle holes or unraveling at the folded edges, especially in high-frequency use scenarios where the risk of breakage increases significantly, resulting in limited tensile strength. In addition, the existing trampoline fabric seams and fabric edges are directly exposed, making them prone to aging and brittle breakage. Utility Model Content

[0003] The purpose of this invention is to provide a trampoline cloth with an edge-reinforced structure, which can effectively solve the problems in the background art.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows: A trampoline fabric with an edge-reinforced structure includes a main fabric. The top and bottom of the main fabric are respectively fixedly connected with reinforcing covering edges along their outer contours. A wrapping flange is also fixedly connected to the outer contour of the main fabric between the two reinforcing covering edges. A pull strap is fixedly connected between the wrapping flange and the two reinforcing covering edges. A fixing piece is fixedly connected to one side of the pull strap. An anti-deformation rod is interlaced between the pull strap and the fixing piece. The main fabric also includes a base material. An anti-aging layer is provided on the outer surface of the base material. An environmental isolation inner layer is provided on the outer surface of the anti-aging layer. An environmental isolation middle layer is provided on the outer surface of the environmental isolation inner layer. An environmental isolation outer layer is provided on the outer surface of the environmental isolation middle layer.

[0005] As a further preferred embodiment of this utility model, the longitudinal section of the reinforcing cover edge is Z-shaped, which can be sewn to the main fabric and then sewn to the wrapping fold and the main fabric again to increase the thickness of the outer contour of the main fabric, thereby improving the tensile strength of the outer contour of the main fabric. The longitudinal section of the wrapping fold is U-shaped, which can wrap around the outer contour of the main fabric to protect the edge of the outer contour of the main fabric.

[0006] As a further preferred embodiment of this utility model, the anti-deformation rod is made of metal, which can prevent the bent part of the pull strap from being forced to move towards the middle and tighten after one end of the spring is connected to the inside of the pull strap, thereby increasing the oblique tension between the two ends of the pull strap and the reinforcing cover edge and the wrapping edge, thus reducing the possibility of tearing between the two ends of the pull strap and the reinforcing cover edge and the wrapping edge.

[0007] As a further preferred embodiment of this utility model, the anti-aging layer is an elastic polyurethane sponge skeleton covered with a fine polyester mesh on the outer surface of the substrate, thereby reducing the stress load on the substrate.

[0008] As a further preferred embodiment of this utility model, the inner environmental isolation layer is a hot melt adhesive layer, the middle environmental isolation layer is a fluorocarbon composite layer, and the outer environmental isolation layer is a UV-resistant modified polyurethane, which can provide the substrate with UV resistance and acid and alkali corrosion resistance.

[0009] Compared with the prior art, the present invention has the following beneficial effects: In this invention, the Z-shaped reinforced covering edge and the U-shaped wrapping edge at the edge of the main fabric work together to increase the thickness of the main fabric edge and the stability of the stitching, avoiding the problem of easy cracking of the single-layer folded seam edge. At the same time, the metal anti-deformation rod can prevent the pull strap from deforming under stress and reduce the risk of tearing when connected to the spring. In the layered structure of the main fabric, the anti-aging layer of the elastic polyurethane sponge skeleton can reduce the stress load on the substrate, and the multi-layer environmental isolation structure reduces the aging and brittle breakage of the seams and fabric edges through anti-UV and anti-corrosion design, thus extending the overall service life of the trampoline fabric.

[0012] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0013] like Figures 1-4As shown, the present invention provides a trampoline fabric with an edge-reinforced structure, comprising a main fabric 1, with reinforcing covering edges 2 fixedly connected to the top and bottom of the main fabric 1 along the outer contour, and a wrapping flange 3 fixedly connected to the outer contour of the main fabric 1 between the two reinforcing covering edges 2. A pull strap 4 is fixedly connected between the wrapping flange 3 and the two reinforcing covering edges 2, and a fixing piece 5 is fixedly connected to one side of the pull strap 4. An anti-deformation rod 6 is inserted between the pull strap 4 and the fixing piece 5. The main fabric 1 also includes a base material 7, with an anti-aging layer 8 on the outer surface of the base material 7, an environmental isolation inner layer 9 on the outer surface of the anti-aging layer 8, an environmental isolation middle layer 10 on the outer surface of the environmental isolation inner layer 9, and an environmental isolation outer layer 11 on the outer surface of the environmental isolation middle layer 10.

[0014] like Figures 2-3 As shown, the longitudinal section of the reinforcing cover edge 2 is Z-shaped. After the reinforcing cover edge 2 is sewn to the main fabric 1, it can be sewn again to the wrapping flange 3 and the main fabric 1, increasing the thickness of the outer contour of the main fabric 1 and thus improving the tensile strength of the outer contour of the main fabric 1. The longitudinal section of the wrapping flange 3 is U-shaped, which can wrap around the outer contour of the main fabric 1 to protect the edge of the outer contour of the main fabric 1. The anti-deformation rod 6 is made of metal, which can prevent the spring end from being connected to the pull strap 4 and causing the bent part of the pull strap 4 to be forced to move towards the middle and tighten, thereby increasing the diagonal tension of the two ends of the pull strap 4 and the reinforcing cover edge 2 and the wrapping flange 3, thus reducing the possibility of tearing of the two ends of the pull strap 4 and the reinforcing cover edge 2 and the wrapping flange 3.

[0015] like Figure 4 As shown, the anti-aging layer 8 is an elastic polyurethane sponge skeleton covered with a fine polyester mesh on the outer surface of the substrate 7, thereby reducing the stress load on the substrate 7. The environmental isolation inner layer 9 is a hot melt adhesive layer, the environmental isolation middle layer 10 is a fluorocarbon composite layer, and the environmental isolation outer layer 11 is a UV-resistant modified polyurethane, which can provide the substrate 7 with UV resistance and acid and alkali corrosion resistance.

[0016] It should be noted that this utility model is a trampoline cloth with an edge-reinforced structure. The main fabric 1 is the core load-bearing component. The reinforcing cover edge 2 of its edge has a Z-shaped longitudinal section, which can form a multi-layer stitched structure with the main fabric 1 and the wrapping fold 3. When the trampoline cloth is subjected to the tensile force generated by the user's jumping, the reinforcing cover edge 2 can increase the edge force-bearing area and distribute the tensile force to the multi-layer fabric, avoiding stress concentration at a single seam or needle hole. At the same time, the wrapping fold 3 has a U-shaped longitudinal section, which directly wraps the outer contour of the main fabric 1, which can isolate the external dust and moisture from direct contact with the edge of the main fabric 1. At the same time, it protects the edge fibers of the main fabric 1 from direct wear during the stretching process. In addition, during installation, the tensile force generated when the spring is connected will be transmitted to the pull strap 4. The anti-deformation rod 6, which is made of metal, is inserted between the pull strap 4 and the fixing piece 5. It can resist the force of the pull strap 4 bending part moving towards the middle and tightening, avoiding excessive diagonal tensile force between the two ends of the pull strap 4 and the reinforcing cover edge 2 and the wrapping fold 3, and reducing the risk of tearing. The substrate 7 of the main fabric 1 serves as the basic load-bearing layer. Its outer surface anti-aging layer 8 is an elastic polyurethane sponge skeleton covered with a fine polyester mesh. When a user jumps and impacts the main fabric 1, the anti-aging layer 8 can buffer the impact force through its own elasticity, reduce the stress load on the substrate 7, and extend the service life of the substrate 7. The environmental isolation inner layer 9 is a hot melt adhesive bonding layer, which can ensure that the anti-aging layer 8 and the environmental isolation middle layer 10 are tightly bonded to avoid interlayer separation. The environmental isolation middle layer 10 is a fluorocarbon composite layer, which can block external acid and alkali substances from corroding the internal structure. The environmental isolation outer layer 11 is a UV-resistant modified polyurethane, which can absorb and reflect ultraviolet rays, preventing long-term exposure of ultraviolet rays from causing aging and brittle fracture of the internal structure such as the substrate 7 and the anti-aging layer 8.
