Problems solved by technology
[0004] The purpose of the present invention is to provide an inflatable mesh high-frequency voltage drawstring structure to solve the force direction position of the drawstring connecting the pad surface and the bottom of the air mattress proposed in the above background technology when it is in use. It is 90 degrees, the force point is concentrated on the right angle, and the pull belt is easy to break due to force

Embodiment
[0023] see Figure 1 to Figure 4 , the present invention provides a technical solution: an inflatable mesh high-frequency voltage drawstring structure, the drawstring 9 is located inside the mattress body, and the mattress body includes a first cushion surface 1, a second cushion surface 2, and a surrounding cushion surface 3, The drawstring 9 is located between the opposing surfaces of the first cushion surface 1 and the second cushion surface 2, and when the drawstring 9 is subjected to forces at different angles from the first cushion surface 1 and the second cushion surface 2, the degree of bifurcation of the drawstring 9 is different , to disperse the applied force, reduce the applied force on the drawstring 9, and prolong the service life of the air mattress. The outside of the middle position of the drawstring 9 is provided with a restraint cover 10, and the second pad surface 2 deviates from the first The surface of the pad surface 1 is provided with a protective mecha...

The invention discloses a high-frequency voltage drawstring structure of an inflatable sandwich net. The drawstrings are positioned in the mattress body; the mattress body comprises a first mattress surface, a second mattress surface and a surrounding mattress surface; the drawstrings are positioned between the opposite surfaces of the first mattress surface and the second mattress surface; a binding sleeve is arranged on the outer side of the middle position of each drawstring, a protection mechanism is arranged on the surface, deviating from the first mattress surface, of the second mattresssurface, the protection mechanism comprises a damp-proof layer and a protection layer, a first bonding layer is arranged on the surface of the damp-proof layer, and a second bonding layer is arrangedon the surface of the protection layer; through the designed drawstrings, when the drawstrings are subjected to different angle acting forces of the first mattress surface and the second mattress surface, due to the fact that the bifurcation degrees of the drawstrings are different, the acting force borne by the drawstrings is dispersed, the acting force borne by the drawstrings is reduced, the service life of the inflatable mattress is prolonged, and through the designed protective layer, when the inflatable mattress is used outdoors, the situation that the mattress is punctured by sharp objects or contaminated and wetted, and consequently the cleaning frequency and time are increased is avoided.
Description
technical field [0001] The invention belongs to the technical field of drawstrings, and in particular relates to a drawstring structure with inflatable clamping net and high frequency voltage. Background technique [0002] At present, the air mattress is more and more popular and popular due to its advantages of convenient portability, easy collection and good comfort. It can not only be used as a spare mattress, but also can be used when camping in the wild. The traditional Inflatable mattresses generally use straight pull straps, S-shaped pull straps, etc., and the air mattress and the pull straps are welded and welded by high-frequency voltage. The high-voltage wave voltage welding has the least damage to the pull straps and the air mattress. After inflating, there will be a vertical pulling force on the dough sheet and the back sheet, and the force will be more concentrated at the seam connecting the draw tape and the dough sheet or the back sheet, which will easily caus...
