[0049] It should be noted that the tie bars provided in this embodiment can be arranged along the inner circumference of the side wall 500. The tie bars can, on the basis of fixing the cover cloth 300 and the base cloth 400, also exert force on the side wall 500 to ensure the curvature of the side wall 500 after inflation; specifically, the main tie bars 100 and the auxiliary tie bars 200 are integrally formed by weaving weaving wires, the main tie bars 100 can be located vertically between the cover cloth 300 and the base cloth 400, the auxiliary tie bars 200 are inclined to the main tie bars 100, and the two ends of the auxiliary tie bars 200 are respectively connected to the main tie bars 100 and the side walls, that is, the auxiliary tie bars 200 can exert an oblique force on the side walls, and the auxiliary tie bars 200 can be used to transmit the curvature extension force of the side wall inflation to the main tie bars 100 and the cover cloth 300 and the base cloth 400 after inflation, thereby limiting the curvature of the side wall 500 when inflated, thereby ensuring the stability of the inflatable product.

When the side wall 500 and the cover cloth 300 are inflated, the curvature of the side is increased, causing the side wall 500 to protrude, resulting in unstable effect of the inflatable product.

[0051] On the basis of the above embodiments, further, in a preferred embodiment of the present invention, two auxiliary tension bars 200 are provided; the two auxiliary tension bars 200 are located on the same side of the main tension bar 100, and the two auxiliary tension bars 200 are symmetrically arranged with respect to the midline of the main tension bar 100, and the height of the main tension bar 100 is arranged corresponding to the height of the side wall 500, and the two auxiliary tension bars 200 are respectively connected to the side wall 500 to form a relatively balanced force on the side wall 500.

A densely woven area 101, namely the first patterned woven area 102, serves as the height side wall position of the main reinforcement 100. By utilizing a low weaving density, the weight of the main reinforcement 100 can be reduced and the air permeability can be improved while ensuring the toughness of the main reinforcement 100. Furthermore, by locally applying glue on the surface of the first densely woven area 101, the local glue is dried to form a first adhesive layer to form the main reinforcement 100. When the main reinforcement 100 needs to be installed on an inflatable product, it only needs to be welded and connected using the position of the first adhesive layer.

[0055] In a preferred embodiment of the present invention, the auxiliary tensioning rod 200 includes a second adhesive layer, a second densely woven area 201 and a second patterned woven area 202, the weaving density of the second patterned woven area 202 is lower than that of the second densely woven area 201; the second patterned woven area 202 is extended and arranged at the interweaving point of the first densely woven area 101 and the first patterned woven area 102, the second patterned woven area 202 is woven into one piece with the first densely woven area 101, the second patterned woven area 202 is arranged at an angle to the first patterned woven area 102, the second densely woven area 201 is woven into one piece with one end of the second patterned woven area 202 away from the first densely woven area 101, the second adhesive layer is connected to the second densely woven area 201, and the second densely woven area 201 is welded and connected to the side wall 500 through the second adhesive layer.

By utilizing the low weaving density, the weight of the auxiliary reinforcement 200 can be reduced and the air permeability can be improved while ensuring the strength of the auxiliary reinforcement 200. Furthermore, by locally applying glue on the surface of the second dense weaving area 201, the local glue is dried to form a second adhesive layer to form the auxiliary reinforcement 200. When the main reinforcement 100 needs to be installed on the inflatable product, it only needs to be welded and connected using the position of the second adhesive layer.

[0065] In this embodiment, when the auxiliary reinforcing bars 200 are woven in a multi-segment manner, each auxiliary reinforcing bar 200 includes a second pattern weaving area 202 and a second dense weaving area 201, that is, the first dense weaving area 101 of the main reinforcing bar 100 is used as the starting point, and the intersection point between the fabric welding surface and the first pattern weaving area 102 is used as the first branch line, and the first pattern weaving area 102 is woven with the first branch line respectively, and at the same time, multiple sections of the second pattern weaving area 202 are independently woven, and the multiple sections of the second pattern weaving area 202 extend along different inclined directions. The second dense weaving area 201 is continued to be woven at the end of each section of the second pattern weaving area 202, so as to complete multiple auxiliary reinforcing bars in the half area of ​​the midline of the main reinforcing bar 100. 200 is weaved; the end of the first pattern weaving area 102 after weaving is used as the second branch line, and the second branch line is used to weave the first dense weaving area 101 respectively, that is, the weaving of two sections of the first dense weaving area 101 and the main reinforcement 100 clamping the middle first pattern weaving area 102 is completed, and at the same time, multiple sections of the second pattern weaving area 202 are independently woven to complete the symmetrical arrangement of multiple sections of the second pattern weaving area 202, and the second dense weaving area 201 is continued to be woven at the end of each section of the second pattern weaving area 202 to complete the weaving of multiple auxiliary reinforcements 200 in the other half of the midline of the main reinforcement 100. Finally, a main reinforcement 100 and multiple auxiliary reinforcements 200 are formed by weaving the reinforcement weaving lines.

[0066] The present embodiment provides a manufacturing process based on the tensioning rod, comprising the following steps: weaving the first dense woven area 101 of the first section according to a preset size, dividing the first dense woven area 101 of the first section into two sections for weaving, so as to weave the first pattern woven area 102 with the same width at both ends along the ends of the first dense woven area 101, wherein the weaving density of the first pattern woven area 102 is lower than that of the first dense woven area 101; combining the ends of the two sections of the first pattern woven area 102 into one to weave the first dense woven area 101 of the second section; cutting the first pattern woven area 102 of any section in the middle, hot pressing half of the welding film 203 on the cutting edge, and hot pressing the other half of the welding film 203 on the side wall 500; and locally applying glue to the surface of each section of the first dense woven area 101.

[0067] In this embodiment, as a method of weaving the reinforcing bar in a split-into-two manner, the auxiliary reinforcing bar 200 no longer weaves the second dense weaving area 201, that is, the first dense weaving area 101 of the main reinforcing bar 100 is used as the starting point, and the end of the first dense weaving area 101 is used as the fabric welding surface. The width of the fabric welding surface can be determined according to the pattern of the surface, and the intersection point of the fabric welding surface and the first pattern weaving area 102 is used as the first branch line, and the first branch line is used to weave two first branches of the same width. The warp and weft densities of the two first pattern weaving areas 102 can be different. The two ends of the first pattern weaving areas 102 are combined into one to weave the first dense weaving area 101. At this time, any one of the two first pattern weaving areas 102 is cut along the center line to form two completely identical second pattern weaving areas 202. At this time, half of the welding film 203 is hot-pressed along the cutting edge, and the other half of the welding film 203 is hot-pressed on the side wall 500 of the inflatable bed to complete the fixation of the auxiliary tensioning rod 200.

[0068] Optionally, the welding film 203 is a double-sided weldable film, which may be TPU or PVC.

[0069] It should be noted that the main reinforcement 100 provided in this embodiment is a C-shaped reinforcement. Regarding the manufacturing process of the C-shaped reinforcement: two sections of the first densely woven areas 101 and one section of the first flower-shaped woven area 102 are used as a stage of the door width cycle, that is, the two sections of the first densely woven areas 101 are used as the two ends of the main reinforcement 100, and the one section of the first flower-shaped woven area 102 is used as the height side wall of the main reinforcement 100. The two sections of the first densely woven areas 101 can be bent relative to the first flower-shaped woven area 102, that is, after the two sections of the first densely woven areas 101 are respectively connected with the cover cloth 300 and the base cloth 400, the first flower-shaped woven area 102 just forms the height side wall of the main reinforcement 100. By using a low weaving density, the weight of the main reinforcement 100 can be reduced and the breathability can be improved.

[0070] Optionally, the structures of the first pattern weaving area 102 and the second pattern weaving area 202 can be multiple, for example: the first is to form a weaving area by a grid structure without manufacturing a pattern, and the grid can be square or diamond; the second is to form a unit pattern by weaving dense lines, and the unit array, symmetry, rotation and other patterns are arranged in an orderly or free arrangement to form a pattern, and the reinforcement line is added in combination with the pattern according to the stress conditions; the third is that for regular patterns, each group or several groups can be directly hollowed out, and the hollowed-out edges are densely packed with weaving lines, i.e. reinforcement ribs, and the number of reinforcement rib groups is not less than the number of patterns; by setting the weaving of the first pattern weaving area 102 and the second pattern weaving area 202, by increasing the density of the weaving lines, increasing the reinforcement ribs and the pattern area, increasing the toughness of the main reinforcement 100 and the auxiliary reinforcement 200, and hollowing out any shape at appropriate positions to reduce the weight and air permeability of the main reinforcement 100 and the auxiliary reinforcement 200.

[0071] The present embodiment provides a manufacturing process based on the tensioning rod, comprising the following steps: sequentially weaving a first section of a first dense woven area 101, a first pattern woven area 102, and a second section of the first dense woven area 101 according to preset dimensions, wherein the weaving density of the first pattern woven area 102 is lower than that of the first dense woven area 101; sequentially weaving a second pattern woven area 202 and a second dense woven area 201 according to preset dimensions, wherein the weaving density of the second pattern woven area 202 is lower than that of the second dense woven area 201; and respectively welding or sewing the two second pattern woven areas 202 to the first section of the first dense woven area 101 and the second section of the first dense woven area 101 at symmetrical positions.

[0072] In the present embodiment, a main tension reinforcement 100 is formed by separately weaving to form two sections of first dense woven areas 101 and one section of first pattern woven area 102 arranged at intervals, and an auxiliary tension reinforcement 200 is formed by separately weaving to form one section of second dense woven area 201 and one section of second pattern woven area 202. The second pattern woven areas 202 of the two auxiliary tension reinforcements 200 are fixedly connected by welding or sewing the symmetrical positions of the two sections of the first dense woven areas 101. That is, the main tension reinforcement 100 and the auxiliary tension reinforcement 200 are formed by separate weaving, and the tension reinforcement is formed by welding or sewing.

[0073] An inflatable product provided in this embodiment includes a cover cloth 300, a base cloth 400, a side wall 500 and a tension rod; the side wall 500 is arranged circumferentially along the edge of the cover cloth 300, and the side wall 500 is respectively connected to the cover cloth 300 and the base cloth 400, and an inflatable space for accommodating the tension rod is formed between the cover cloth 300, the side wall 500 and the base cloth 400; the main tension rod 100 is located between the cover cloth 300 and the base cloth 400, and adhesive layers are arranged at intervals along the two side surfaces of the main tension rod 100, and the main tension rod 100 is respectively connected to the cover cloth 300 and the base cloth 400 through the adhesive layers on both sides through a hot melt process; the auxiliary tension rod 200 is located on a side close to the side wall 500, and one end of the auxiliary tension rod 200 extends out of the main tension rod 100 and is connected to the two ends of the side wall 500 toward the cover cloth 300 and the base cloth 400, so as to limit the curvature of the side wall 500 through the cover cloth 300 and the base cloth 400.

[0074] In the present embodiment, by using the tie bars in the application of the inflatable mattress, the cover cloth 300 and the base cloth 400 can both be made of TPU coated fabrics, which are environmentally friendly and wear-resistant and suitable for a variety of outdoor environments; by arranging tie bars between the cover cloth 300 and the base cloth 400 near the side wall 500, for the square structure inflatable mattress, four tie bars can be provided, and the four tie bars correspond to the four side walls 500 respectively, and the opposite sides of the main tie bars 100 are hot-melt connected with the cover cloth 300 and the base cloth 400 through the local glue coating position, so that the welding point of the air bed is concave downward after inflation, and conversely, other places bulge upward, so that the surface of the inflatable mattress forms a multi-layer surface. The auxiliary reinforcement 200 has a flower pattern and acts as a supporting column at the same time. The two ends of the auxiliary reinforcement 200 are respectively connected to the main reinforcement 100 and the side wall, that is, the auxiliary reinforcement 200 can exert an oblique force on the side wall. The auxiliary reinforcement 200 can transmit the arc extension force of the inflated side wall to the main reinforcement 100 and the inflated cover cloth 300 and the base cloth 400, thereby limiting the arc extended by the inflated side wall 500. By providing an air valve on the inflatable mattress, the technical effects of fast inflation and deflation and convenient carrying are achieved; through the practical application of the reinforcement, the reinforcement has the effect of light weight and ventilation, which ensures faster inflation and deflation and improves efficiency.
