Correspondingly, a reinforcing plate 14 is bonded to the inner wall of the bonding plate 11, and the reinforcing plate 14 is a polyvinyl chloride elastic plate. Through the design of the PVC, the mounting plate 3 and the reinforcing plate 14 in the bonding plate 11, since the reinforcing plate 14 is made of a polyvinyl chloride elastic plate, it has a certain anti-bending and anti-folding effect, which is convenient for increasing the overall structure of the PVC plate 1. At the same time, by utilizing the setting of a plurality of plastic reinforcing rods 13, the internal structure of the entire plate can be supported and stressed when the entire plate is squeezed and bent to avoid excessive bending and causing the plate to break.

[0033] In this embodiment, Figure 1 and Figure 3 As shown, a plurality of holes are provided on the outer wall of the PVC board 1, and the plurality of holes are horizontally distributed at equal intervals, and the plurality of holes are of different sizes. A wear-resistant coating is applied on the outer wall of the PVC board 1.

The outer wall of the sealing ring 253 is slidingly matched with the inner wall of the sealing chamber 25. The two sides of the rear end of the sealing ring 253 are respectively fixedly connected to two groups of connecting rods 252. With the continuous forward movement of the mounting plate 3, the mounting plate 3 pushes the hinge 22 to contract. Since the hinge 22 is arranged in a parallelogram structure, the rear end of the hinge 22 is arranged through the connecting plate 251 and the connecting rod 252, and the sealing ring 253 is pushed forward and inserted into the sealing block 7 to fill the gap between the sealing block 7 and the sealing chamber 25 to prevent foreign matter from penetrating into the interior of the plug-in board 2 and causing corrosion of the internal structure.

[0036] In this embodiment, Figure 2 and Figure 6 As shown, slots are provided on the outer walls at both ends of the plug board 2, and elastic clips 4 are fixed on both ends of the outer wall of the mounting plate 3, and two groups of elastic clips 4 are arranged one-to-one with the two groups of slots, and the elastic clips 4 are snap-connected with the slots. As the mounting plate 3 is continuously inserted into the plug board 2, the elastic clips 4 move to the front of the slots, and the bottom ends of the elastic clips 4 are squeezed and moved downward, causing the elastic clips 4 to be inserted into the slots, so that the mounting plate 3 and the plug board 2 can be fixed together.

[0037] In this embodiment, Figure 2 and Figure 6 As shown, a plug-in block 5 is fixed on the outer wall of one side of the mounting plate 3, a protrusion 6 is fixed at the front end of the plug-in block 5, a sealing block 7 is horizontally arranged below the plug-in block 5, and the rear end of the sealing block 7 is fixedly connected to the outer wall of the mounting plate 3, and the outer contour of the sealing block 7 matches the inner contour of the sealing ring 253, so that the combination of the sealing block 7 and the sealing ring 253 can not only increase the connection effect between the mounting plate 3 and the plug-in board 2, but also increase the sealing performance, thereby preventing external water stains from penetrating into the plug-in board 2, causing corrosion and aging of internal components, and resulting in an unstable connection structure.

[0038] In this embodiment, Figures 1 to 6 As shown, a production process of high-strength PVC folding-resistant board is characterized in that it includes the following steps:

[0039] S1, mixing: select PVC plasticizer, stabilizer, lubricant, send the raw materials into a mixer to fully mix the materials, send the mixed materials into a heating furnace to heat and melt, send the hot melt into an injection molding machine, cool and mold through a mold to obtain a PVC board 1, a bonding board 11 and a mounting board 3;

[0040] S2, processing: placing the PVC board 1 and the laminated board 11 in a cutting machine, cutting them to size and performing secondary processing, and then cutting the surface of the laminated board 11 to form a placement groove 12 for placing the reinforcing rod 13;

[0041] S3, select a plurality of reinforcing rods 13 made of plastic material, place the plurality of reinforcing rods 13 one by one in the interior of the placement groove 12, and inject molten plastic into the placement groove 12 to completely fix the reinforcing rods 13 to the inner wall of the bonding plate 11;

[0042] S4, assembly: placing the assembled laminated board 11 on a hot press, and selecting a reinforcing plate 14 of a polyvinyl chloride elastic sheet to place at the bottom of the laminated board 11, and tightly bonding them by the hot press, and then placing another set of laminated boards 11 under the reinforcing plate 14 and performing hot pressing and bonding again, so as to fix the reinforcing plate 14 inside the laminated board 11, and performing the same operation on the PVC board 1;

[0043] S5, assembly: the hot press is used again to heat-press and bond the assembled PVC board 1 and the laminated board 11 together, a slide groove is drilled on the entire assembled board by an external punching machine, and the sliding block at the rear end of the plug-in board 2 is manually inserted into the entire board by the installation tool to complete the production of the entire board.

[0044] It should be noted that a production process of a high-strength PVC folding-resistant board, when working, through the design of the reinforcing plate 14 in the PVC board 1, the mounting plate 3 and the bonding plate 11, because the reinforcing plate 14 is set with a polyvinyl chloride elastic plate, it has a certain anti-bending and anti-bending effect, which is convenient for increasing the overall structure of the PVC board 1, and at the same time, by using the setting of a plurality of plastic reinforcing rods 13, when the entire board is squeezed and bent, the internal structure of the entire board can be supported and stressed to avoid excessive bending and causing the board to break, and a plurality of holes of different sizes are opened on the outer wall of the PVC board 1, so that when the wear-resistant coating is sprayed, the wear-resistant coating can be well attached to the surface of the PVC board 1, and the setting of the wear-resistant coating can reduce the wear of the PVC board 1 by external friction, and avoid changes in the structure of the PVC board 1;

[0045] Secondly, the staff can manually insert the plug board 2 by sliding, fix the plug board 2 on the PVC board 1, and manually insert another set of PVC boards 1, that is, the mounting board 3, into the adjustment chamber 21 and the sealing chamber 25 on the entire PVC board 1, so that the plug block 5 on the mounting board 3 drives the protrusion 6 to move forward, and the protrusion 6 is inserted into the limiting groove 24 to limit the position of the mounting board 3. Then, with the continuous forward movement of the mounting board 3, the elastic buckle 4 is inserted into the card slot for fixing;

[0046] As described above, with the continuous forward movement of the mounting plate 3, the mounting plate 3 pushes the hinge 22 to contract. Since the hinge 22 is arranged in a parallelogram structure, the rear end of the hinge 22 is caused to move forward through the setting of the connecting plate 251 and the connecting rod 252, and pushes the sealing ring 253 to move forward and insert it into the sealing block 7 to fill the gap between the sealing block 7 and the sealing chamber 25, so that the sealing ring 253 can not only increase the connection effect between the mounting plate 3 and the plug-in board 2, but also increase the sealing performance, thereby preventing external water stains from penetrating into the plug-in board 2, causing corrosion and aging of internal components, and resulting in an unstable connection structure.
