[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. 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.

[0020] The utility model provides Figure 1-3 The crack-resistant and pressure-resistant composite plastic structure shown comprises an anti-crack layer a1 and a pressure-resistant layer 2 installed on the anti-crack layer a1;

[0021] The lower outer wall of the pressure-resistant layer 2 is fixedly connected with a base layer 3;

[0022] The lower end outer wall of the base layer 3 is fixedly connected with an anti-crack layer b4. The anti-crack layer a1 and the anti-crack layer b4 are used to bear the tensile stress of the composite plastic under external pressure to prevent the composite plastic from cracking. The pressure-resistant layer 2 increases the pressure resistance of the composite plastic and increases the pressure resistance. The base layer 3 is the main body of the composite material and bears the loads of the anti-crack layer a1, the pressure-resistant layer 2 and the anti-crack layer b4.

[0023] A plurality of connecting blocks 5 are equidistantly arranged between the anti-crack layer a1, the anti-compression layer 2, the base layer 3 and the anti-crack layer b4 to connect the positions of the anti-crack layer a1, the anti-compression layer 2, the base layer 3 and the anti-crack layer b4. The upper and lower outer walls of the plurality of connecting blocks 5 are coated with adhesive 6 to assist in bonding the anti-crack layer a1, the anti-compression layer 2, the base layer 3 and the anti-crack layer b4 to the connecting blocks 5. When the anti-crack layer a1, the anti-compression layer 2, the base layer 3 and the anti-crack layer b4 are fixed by the adhesive, the anti-crack layer a1, the anti-compression layer 2, the base layer 3 and the anti-crack layer b4 are bonded to the anti-crack layer a1. A plurality of connecting blocks 5 are arranged between layer 2, base layer 3 and anti-crack layer b4, and adhesive 6 is coated on the upper and lower sides of the connecting blocks 5. When the anti-crack layer a1, the anti-pressure layer 2, the base layer 3 and the anti-crack layer b4 are pressed after being bonded together, the connecting blocks 5 and adhesive 6 fixed at the edges between the anti-crack layer a1, the anti-pressure layer 2, the base layer 3 and the anti-crack layer b4 can increase the connection strength at the edges between the anti-crack layer a1, the anti-pressure layer 2, the base layer 3 and the anti-crack layer b4, thereby reducing the risk of separation and detachment between the layers.

[0024] like Figure 3 As shown, the lower end outer walls of the anti-crack layer a1, the pressure-resistant layer 2 and the base layer 3 are all equidistantly provided with a plurality of upper grooves 7 opening downward, the pressure-resistant layer 2, the base layer 3 and the anti-crack layer b4 are all equidistantly provided with a plurality of lower grooves 8 opening upward for the connection block 5 to be snapped in, the lower end outer walls of the anti-crack layer a1, the pressure-resistant layer 2 and the base layer 3 are all equidistantly provided with a plurality of compensating gaps b10 opening downward, the pressure-resistant layer 2, the base layer 3 and the anti-crack layer b4 are all equidistantly provided with a plurality of compensating gaps a9 opening upward to reduce stress concentration caused by compression.

[0025] By providing the upper groove 7 and the lower groove 8, when placing the connecting block 5, the connecting block 5 can be placed in the gap between the upper groove 7 and the lower groove 8 for storage, and after the composite plastic is subjected to pressure, the compensating gap a9 and the compensating gap b10 can be used to reduce the stress concentration caused by the pressure, thereby avoiding the occurrence of gaps between the layers.

[0026] like Figure 3As shown, the vertical lengths of the multiple connecting blocks 5 are all smaller than the vertical lengths of the anti-crack layer a1, the anti-compression layer 2, the base layer 3 and the anti-crack layer b4, the adhesive 6 and the adhesive used between the anti-crack layer a1, the anti-compression layer 2, the base layer 3 and the anti-crack layer b4 are the same, all of which are plastic adhesives, and the multiple connecting blocks 5 are all made of polypropylene material, and the multiple connecting blocks 5 are the same size.

[0027] Using the same adhesive can ensure the stability of the connection between the layers after they are connected by the adhesive 6, while reducing the complexity of using different adhesives 6. The connecting block 5 made of polypropylene material can increase the stability after the connection when using the adhesive 6, and avoid the situation where different materials of plastics cannot be bonded.

[0028] like Figure 1 As shown, the anti-cracking layer a1 and the anti-cracking layer b4 are both made of polypropylene fibers, and the anti-pressure layer 2 is made of polyethylene material.

[0029] The anti-cracking layer a1 and the anti-cracking layer b4 composed of polypropylene fibers can increase the anti-cracking performance of the plastic surface layer, and the pressure-resistant layer 2 made of polyethylene material has higher pressure resistance and wear resistance.

[0030] The implementation principle of this embodiment is as follows: the anti-crack layer a1 and the anti-crack layer b4 bear the tensile stress of the composite plastic under external pressure to prevent the composite plastic from cracking; the anti-pressure layer 2 increases the compressive capacity of the composite plastic and increases the compressive performance; the base layer 3 is the main body of the composite material and bears the loads of the anti-crack layer a1, the anti-pressure layer 2 and the anti-crack layer b4; when the anti-crack layer a1, the anti-pressure layer 2, the base layer 3 and the anti-crack layer b4 are fixed by an adhesive, a plurality of connecting blocks 5 are arranged between the anti-crack layer a1, the anti-pressure layer 2, the base layer 3 and the anti-crack layer b4, and an adhesive 6 is coated on the upper and lower sides of the connecting blocks 5; when the anti-crack layer a1, the anti-pressure layer 2, the base layer 3 and the anti-crack layer b4 are adhered and pressed tightly, the connecting blocks 5 and the adhesive 6 fixed at the edges between the anti-crack layer a1, the anti-pressure layer 2, the base layer 3 and the anti-crack layer b4 can increase the connection strength at the edges between the anti-crack layer a1, the anti-pressure layer 2, the base layer 3 and the anti-crack layer b4, thereby reducing the risk of separation and detachment between the layers.

[0031] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention.
