[0013] Technical effects and advantages of the utility model:

[0014] 1. In the actual operation of the utility model, when the rubber pad is subjected to pressure as a whole, the second natural rubber layer and the polyurethane rubber layer will rebound due to the characteristics of their own materials.

DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the embodiments of the utility model to clarify the technical solutions in the embodiments of the utility model; it is completely described. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of them. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] The utility model provides Figure 1-Figure 3 A highly sealing heat-resistant rubber pad structure shown in the figure includes a first natural rubber layer 8 and a reinforcing plate 13. The reinforcing plate 13 is arranged directly below the first natural rubber layer 8. A gap is arranged between the reinforcing plate 13 and the first natural rubber layer 8. A plurality of first fixing boxes 6 and a plurality of second fixing boxes 9 are fixedly connected to the opposite sides of the reinforcing plate 13 and the first natural rubber layer 8, respectively. The positions of the first fixing boxes 6 and the second fixing boxes 9 correspond to each other. A groove is provided on the opposite sides of the first fixing boxes 6 and the second fixing boxes 9. An elastic hose 10 is fixed inside the groove of the first fixing box 6. A reset spring 12 is connected inside the elastic hose 10. The bottom end of the elastic hose 10 is engaged in the groove of the second fixing box 9. Through holes 11 are provided on both sides of the second fixing box 9. The outer sides of the first natural rubber layer 8 and the reinforcing plate 13 are connected to a wear-resistant outer package 2. An air hole 4 is provided on one side of the wear-resistant outer package 2. A connecting port 5 is extended out from the other side of the wear-resistant outer package 2. The air hole 4 and the connecting port 5 are both connected to the gap.

[0022] The first natural rubber layer 8 and the reinforcing plate 13 are respectively sealed and connected with the polyurethane rubber layer 7 and the second natural rubber layer 14 on the side away from each other through an environmentally friendly hot-melt film.

[0023] The top of the polyurethane rubber layer 7 is connected to the wear-resistant layer 1, and the bottom of the second natural rubber layer 14 is connected to the bottom layer 15. The outer sides of the wear-resistant layer 1, the bottom layer 15 and the wear-resistant outer package 2 are all provided with heat-resistant layers.

[0024] The top of the wear-resistant layer 1 is fixedly connected with a plurality of anti-skid pads 3. The bottom end of the bottom layer 15 is provided with anti-skid grooves.

[0025] In this embodiment, when a heat-resistant rubber pad is used, the bottom layer 15 uses a wear-resistant material. Through the setting of the bottom layer 15, the wear resistance of the bottom can be greatly improved, and the anti-slip pattern can greatly increase the grip of the wear-resistant bottom layer 15, thereby improving the overall anti-slip performance. Through the characteristics of the first natural rubber layer 8 and the polyurethane rubber layer 7, it can have the characteristics of tear resistance, ozone resistance, aging resistance, wear resistance and drought resistance. Since the outer sides of the wear-resistant layer 1, the bottom layer 15 and the wear-resistant outer package 2 are all provided with a heat-resistant layer, the overall rubber pad can have a heat-resistant effect.

[0026] The lengths of the top and bottom ends of the wear-resistant outer package 2 are flush with the wear-resistant layer 1 and the bottom layer 15 respectively, and can wrap the outer side of the entire rubber pad.

[0027] In the actual operation of the present invention, when the rubber pad is subjected to pressure as a whole, the second natural rubber layer 14 and the polyurethane rubber layer 7 will rebound due to the characteristics of their own materials, and at the same time, the squeezing force will squeeze the second fixing box 9 through the elastic hose 10 at the bottom of the first fixing box 6. The elastic hose 10 itself is elastic and cooperates with the use of the return spring 12. The elastic force of the entire rubber pad can be increased, and when the main body of the rubber pad is squeezed, it plays a buffering role.

[0028] In addition, when the elastic hose 10 is squeezed, the air flow in the gap will move, and through the cooperation of the air hole 4 and the through hole 11, the gas can be discharged to the outside, so as to prevent the rubber pad from being affected by the internal space and air flow of the heat, and the accumulation of water vapor in the gap. The air hole 4 of a rubber pad can be connected with the connection port 5 of another rubber pad, so that it is convenient for personnel to splice and align multiple rubber pads.

[0029] Working principle: In the actual operation of the utility model, when the rubber pad is subjected to pressure as a whole, the second natural rubber layer 14 and the polyurethane rubber layer 7 will rebound due to the characteristics of their own materials, and at the same time, the squeezing force will squeeze the second fixing box 9 through the elastic hose 10 at the bottom of the first fixing box 6. The elastic hose 10 itself is elastic and cooperates with the use of the return spring 12. The elastic force of the entire rubber pad can be increased, and when the main body of the rubber pad is squeezed, it plays a buffering role.

[0030] In addition, when the elastic hose 10 is squeezed, the air flow in the gap will move, and through the cooperation of the air hole 4 and the through hole 11, the gas can be discharged to the outside, so as to prevent the rubber pad from being affected by the internal space and air flow due to the heat, and the accumulation of water vapor in the gap. The air hole 4 of one rubber pad can be matched and connected with the connection port 5 of another rubber pad, so that personnel can easily splice and align multiple rubber pads.

[0031] In this embodiment, when a heat-resistant rubber pad is used, the bottom layer 15 uses a wear-resistant material. Through the setting of the bottom layer 15, the wear resistance of the bottom can be greatly improved, and the anti-slip pattern can greatly increase the grip of the wear-resistant bottom layer 15, thereby improving the overall anti-slip performance. Through the characteristics of the first natural rubber layer 8 and the polyurethane rubber layer 7, it can have the characteristics of tear resistance, ozone resistance, aging resistance, wear resistance and drought resistance. Since the outer sides of the wear-resistant layer 1, the bottom layer 15 and the wear-resistant outer package 2 are all provided with a heat-resistant layer, the overall rubber pad can have a heat-resistant effect.
