To sum up, the utility model discloses a following at least one useful technological effect:
1. the surface rubber layer and the air cushion layer are separated by the supporting layer, and the integral deformation resistance of the rubber blanket is improved by the supporting layer, so that the rubber blanket is not easy to collapse in the using process;
2. the connecting strength between the supporting layer and the surface adhesive layer is increased through the connecting piece, so that the supporting layer and the surface adhesive layer are not easy to crack;
3. the elastic force of the supporting sheet provides resilience force, so that the recovery speed of the rubber blanket after deformation is accelerated;
4. when the rubber blanket is deformed after being used for a long time, the rubber blanket can be restored to the original shape through the memory performance of the memory alloy.
Drawings
FIG. 1 is a schematic structural view of example 1;
FIG. 2 is a schematic structural view of example 2;
FIG. 3 is a schematic structural view of embodiment 3.
In the figure, 1, an air cushion layer; 2. a surface glue layer; 3. weaving a cloth layer; 4. a support layer; 5. a connecting member; 51. connecting sheets; 52. salient points; 6. a water-barrier film; 7. a support sheet; 8. a wire framework.
Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings.
Example 1:
referring to fig. 1, for the utility model discloses a rubber cloth, including air cushion layer 1 and surface glue layer 2, wherein surface glue layer 2 adopts antistatic rubber to form. A fabric layer 3 is adhered on the surface of the air cushion layer 1 opposite to the surface adhesive layer 2. A supporting layer 4 formed by elastic woven cloth is arranged between the air cushion layer 1 and the surface adhesive layer 2, and the supporting layer 4 is adhered and fixed on the air cushion layer 1. The thickness of the support layer 4 is smaller than the thickness of the air cushion layer 1.
Be located and be provided with flexible connecting piece 5 between face glue film 2 and the supporting layer 4, connecting piece 5 is fixed together through the viscose paste between face glue film 2 and the supporting layer 4 respectively. The connecting piece 5 comprises a flexible connecting piece 51 attached to the surface of the support layer 4, and the connecting piece 51 and the support layer 4 are fixed together through thread stitching. A plurality of salient points 52 which are integrally formed with the connecting sheet 51 are arranged on the surface of the connecting sheet 51, which is away from the support layer 4, and the salient points 52 are uniformly distributed on the surface of the connecting sheet 51. Adjacent bumps 52 are spaced apart.
