Detailed implementation mode

[0025] Embodiment 1

[0026] As Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 6 and Figure 7 shown, a PVC composite partition board proposed in this embodiment includes:

[0027] A plurality of PVC composite boards 1, the PVC composite board 1 includes a substrate 14, a PVC foam layer 15, a heat preservation layer 16 and two flame-retardant sound insulation layers 13, and the substrate 14, the PVC foam layer 15, and the heat preservation layer 16 are all arranged between the two flame-retardant sound insulation layers 13; A plurality of connecting pieces 18 are connected between the two flame-retardant sound insulation layers 13; the cross-section of the connecting piece 18 is an "I"-shaped structure, and the arranged connecting piece 18 can improve the bonding stability between the layers of the PVC composite board 1, so that the PVC composite board 1 is not prone to the phenomenon of hollowing; A plurality of high-toughness metal plates 17 are arranged side by side on the inner side of the PVC composite board 1, and the arranged high-toughness metal plates 17 can increase the anti-deformation ability of the PVC composite board 1; A number of transparent anti-wear protrusions are arranged on the outer surface of the PVC composite board 1; Plug-in boards 3 are connected to the sides of the remaining plurality of PVC composite boards 1 except the PVC composite board 1 arranged on one side, and fitting grooves 101 that match the plug-in boards 3 are formed on the other sides of the plurality of PVC composite boards 1.

[0028] Both the upper and lower ends of the PVC composite board 1 are provided with square columns 2. A transmission shaft 7 is rotatably installed inside the square column 2. The transmission shaft 7 penetrates through both ends of the square column 2. Both ends of the transmission shaft 7 have magnetism, and the magnetism at both ends of the transmission shaft 7 attracts each other. This setting enables adjacent two PVC composite boards 1 to be adsorbed together before being fixed. One end of the transmission shaft 7 is connected with a cross-shaped block 12, and a cross-shaped groove b701 that fits with the cross-shaped block 12 is opened at the other end of the transmission shaft 7. A circular groove 201 is opened inside the square column 2, and a cam 8 is arranged inside the circular groove 201. The cam 8 is connected with the transmission shaft 7. An elastic limiting component is installed on the square column 2. The elastic limiting component includes a guide rod 9, a spring 10, and a hemispherical block 11. The guide rod 9 movably penetrates through the side of the square column 2. The inner end of the guide rod 9 is arranged inside the circular groove 201 and is connected with the hemispherical block 11. The spring 10 is sleeved on the guide rod 9. The guide rod 9 fits with the limiting groove. Limiting grooves are opened at both the upper and lower ends of the insertion plate 3. Locking bolts 4 are threadedly connected to both of the square columns 2 on one side, and a plurality of positioning grooves 702 are opened on both of the corresponding transmission shafts 7.

[0029] In this embodiment, a plurality of PVC composite boards 1 are combined and spliced into partition boards. When disassembling a plurality of PVC composite boards 1, first loosen the two locking bolts 4 to move the ends of the locking bolts 4 out of the corresponding positioning grooves 702, thereby releasing the limiting work on the transmission shaft 7. Subsequently, rotate the cross-shaped block 12 arranged on the side, which drives a plurality of transmission shafts 7 to rotate synchronously. As the convex point of the cam 8 separates from the hemispherical block 11, subsequently, under the elastic force of the spring 10, the guide rod 9 is driven to move, so that the guide rod 9 moves out of the limiting groove, thereby releasing the limiting work on a plurality of fitting insertion plates 3. Subsequently, a plurality of PVC composite boards 1 can be pulled in sequence, so that the fitting insertion plates 3 move out of the inside of the fitting groove 101, thereby releasing the limiting connection work of a plurality of PVC composite boards 1; when splicing a plurality of PVC composite boards 1, arrange a plurality of PVC composite boards 1 side by side, so that a plurality of fitting insertion plates 3 are respectively inserted into the corresponding fitting grooves 101. Subsequently, rotate the transmission shaft 7 so that the convex point of the cam 8 contacts the hemispherical block 11, forcing the end of the guide rod 9 to be inserted into the limiting groove, thereby completing the limiting connection work of a plurality of PVC composite boards 1.

When disassembling and assembling, the slotted block 12 on the side corresponding to the slotted hole a501 on the turntable 5 is aligned, so that the slotted block 12 is inserted into the slotted hole a501. Subsequently, the handle 6 is rotated, and by increasing the lever arm, it is possible to facilitate the driving of multiple transmission shafts 7.
