[0029] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the utility model.

[0030] Embodiment one:

[0031] As shown in the technical solutions shown in Figure 1 , Figure 3 , Figure 4 , Figure 5 and Figure 6 , in order to solve the problem that the traditional plastic hollow plate is prone to breaking after being stressed due to its own strength problem when in use, thereby affecting the service life of the hollow plate itself, the multi-layer composite high-strength plastic hollow plate discloses a reinforcing mechanism, which comprises a first air-permeable plate 3, a heat preservation layer 1 is arranged above the first air-permeable plate 3, a reinforcing rod 6 is installed at one end between the two first air-permeable plates 3, a reinforcing mechanism for increasing strength is arranged at one end between the two first air-permeable plates 3, the reinforcing mechanism comprises a support frame 5, the support frame 5 is arranged on one side between the reinforcing rods 6, the cross section of the support frame 5 is in the shape of an inverted "V", and the left and right sides of the support frame 5 are connected with the side of the reinforcing rod 6, cavities 7 are arranged in the inner sides of the reinforcing rod 6 and the support frame 5, and the reinforcing rod 6 and the support frame 5 are intermittently arranged relative to each other.

[0032] In this example, by adding the reinforcing rod 6 to the inside of the second air-permeable plate 4, the strength of the hollow plate when in use is increased after the combination between the two second air-permeable plates 4 and the reinforcing rod 6. The breaking of the plate material when in use due to stress can be avoided by increasing the strength of the hollow plate. The core role of the support frame 5 and the reinforcing rod 6 is to enhance the strength and rigidity of the plastic hollow plate. Due to the structural characteristics of the hollow plate, its strength and rigidity may be relatively weak, especially when subjected to external force, it is prone to deformation. Through the mutual cooperation of the support frame 5 and the reinforcing rod 6, the bending strength and torsional strength of the plate material can be effectively improved, so that it can withstand greater external force without deformation.

[0033] Embodiment two:

[0034] As shown in the technical solutions shown in Figure 1 , Figure 2 , Figure 3 andFigure 4 The technical scheme shown is to solve the problem of poor air permeability of the hollow plate during use: the multi-layer composite high-strength plastic hollow plate discloses an air permeation mechanism, a second air permeation plate 4 is arranged above the first air permeation plate 3, and the surfaces of the first air permeation plate 3 and the second air permeation plate 4 are provided with air permeation mechanisms for air exhaust, the air permeation mechanism comprises a first air permeation hole 9, and the first air permeation hole 9 is arranged on the surface of the first air permeation plate 3, the surface of the second air permeation plate 4 is provided with a second air permeation hole 10, the positions of the first air permeation hole 9 and the second air permeation hole 10 are staggered with each other, the second air permeation hole 10 is arranged above the support frame 5 and the reinforcing rod 6, and the second air permeation hole 10 is in communication with the cavity 7.

[0035] In this example, the first air permeation hole 9 and the second air permeation hole 10 arranged on the surfaces of the first air permeation plate 3 and the second air permeation plate 4 can assist the hollow plate in air exchange and air permeation, and the staggered arrangement of the first air permeation hole 9 and the second air permeation hole 10 can increase the air flow channel, thereby ensuring the efficiency of the whole during air permeation. The hollow structure of the plastic hollow plate allows a large number of air channels to exist inside, which allows air to flow inside the plate, thereby improving the air permeability of the plate. When there is a pressure difference between the external air and the internal air of the plate, air will exchange through these channels to achieve the effect of air permeation. The air permeability of the plastic hollow plate can maintain good ventilation inside the packaging, avoiding the influence of long-term sealing on product quality.

[0036] Embodiment three:

[0037] As shown in Figure 1 and Figure 4 The technical scheme shown is to solve the problem of wear on the surface of the hollow plate after long-term use: the multi-layer composite high-strength plastic hollow plate discloses a wear-resistant mechanism, the surface of the heat preservation layer 1 is provided with a wear-resistant strip 2, and the bottom end of the first air permeation plate 3 is provided with a wear-resistant layer 8. The cross section of the wear-resistant strip 2 is semicircular, and the wear-resistant strips 2 are arranged at equal intervals on the surface of the heat preservation layer 1.

[0038] In this example, by arranging separate heat preservation layers 1 and wear-resistant layers 8 on the surfaces of the two first air permeation plates 3, the heat preservation layer 1 can increase the heat preservation performance, avoiding the influence of the air permeation mechanism on the heat preservation performance of the hollow plate. The wear-resistant strips 2 on the surface of the heat preservation layer 1 can increase the wear resistance of the heat preservation layer 1 during use, preventing the surface of the heat preservation layer 1 from being worn due to long-term use. The wear-resistant layer 8 can protect the bottom end of the first air permeation plate 3 below, preventing the bottom end of the first air permeation plate 3 from being affected by wear due to long-term friction.

[0039] Although the embodiments of the present application have been shown and described, it is to be understood that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present application, the scope of which is defined by the appended claims and their equivalents.
