[0019] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0020] See also Figure 1-3The present invention provides a technical solution: an anti-deformation sound-insulating PVC wood-plastic composite floor, comprising a PVC sheet 1, a through hole 2, a receiving hole 3, a spring 4, a moisture-absorbing layer 5, a vent hole 6, a sealing block 7, a sound-absorbing board 8, an extruded board 9, a keel 10, a connecting groove 11, a connecting block 12, an elastic pad 13 and an anti-slip layer 14, wherein the PVC sheet 1 is provided with a through hole 2 inside, and a receiving hole 3 is provided below the through hole 2, the through holes 2 are arranged in equal intervals in the PVC sheet 1, and the connection method between the PVC sheets 1 and the PVC sheets 1 is as follows: The PVC sheet 1 and the keel 10 form a mortise and tenon structure, and the air inside the through hole 2 is drained. The inside of the through hole 2 is a vacuum structure, so that the PVC sheet 1 has the function of heat preservation and heat insulation. A spring 4 is arranged below the receiving hole 3, and a moisture absorption layer 5 is arranged below the spring 4. The moisture absorption layer 5 and the PVC sheet 1 form a telescopic structure, and the PVC sheet 1 is connected to the moisture absorption layer 5 through the spring 4. The spring 4 can prevent the PVC sheet 1 from directly contacting the moisture absorption layer 5, and the spring 4 can make the PVC sheet 1 in a certain space. The air vent 6 is located on the outside of the spring 4, and a sealing block 7 is arranged inside the air vent 6. The air vent 6 passes through the PVC sheet 1, and there are two groups of air vents 6, and the connection between the air vent 6 and the sealing block 7 is a snap connection. The air vent 6 is used for ventilation and air permeability. The air vent 6 can prevent the indoor temperature from being too high and causing damage to the PVC sheet 1. The sound-absorbing board 8 is located on the lower surface of the moisture-absorbing layer 5, and an extruded board 9 is arranged inside the sound-absorbing board 8. The sound-absorbing board 8 has a "T"-shaped porous structure, and the sound-absorbing boards 8 are evenly spaced. Distributed on the lower surface of the moisture-absorbing layer 5, the sound-absorbing board 8 can absorb indoor sound to prevent external sound from entering the room or indoor sound from being transmitted to the outside. The keel 10 is located on the lower surface of the PVC board 1, and a connecting groove 11 is provided on the left side of the PVC board 1, and a connecting block 12 is provided on the right side of the PVC board 1. The connecting groove 11 is in a "U"-shaped structure, and the connecting groove 11 is connected to the connecting block 12 through an elastic pad 13, so that the PVC board 1 monomers are easy to install, and the anti-slip layer 14 is located on the upper surface of the PVC board 1.

[0021] Working principle: When using the anti-deformation sound-insulating PVC wood-plastic composite floor, firstly, the PVC sheet 1 is spliced ​​with the PVC sheet 1 by using the connection groove 11 and the connection block 12. An elastic pad 13 is arranged between the connection groove 11 and the connection block 12. The elastic pad 13 can leave space between the two PVC sheets 1 to prevent the PVC sheets 1 from being squeezed and deformed. The air inside the through hole 2 is evacuated by using a tool, and the through hole 2 becomes a vacuum structure, so that the PVC sheet 1 has the function of heat preservation and heat insulation. The spring 4 connects the PVC sheet 1 with the moisture absorption layer 5 to prevent the PVC sheet 1 from directly contacting with the moisture absorption layer 5 and preventing the PVC sheet 1 from being deformed when it encounters water. In addition, the spring 4 can provide the PVC sheet 1 with vertical space for movement. The sound-absorbing board 8 can isolate the sound from entering and outputting, and has the effect of sound insulation. The extruded board 9 has excellent thermal insulation, which can avoid the influence of outdoor temperature on the indoor temperature. Then, the PVC board 1 is connected to the keel 10 through the mortise and tenon structure, which reduces the use of glue and strengthens the stability of the connection. The anti-slip layer 14 is glued and connected to the PVC board 1. When the indoor temperature is too high, the sealing block 7 inside the air vent 6 is taken out, and the inside of the PVC board 1 is ventilated and heat-dissipated to avoid high temperature damage to the PVC board 1. The above is to complete a series of operations of the anti-deformation sound-insulating PVC wood-plastic composite floor.
