[0027] The quick-release assembly 6 is used for quickly replacing the suction cup 4 at the bottom of the sheet body 1 .
[0028] For further information, see Figure 1 , Figure 2 and Figure 3 In this embodiment, the quick-release assembly 6 includes a connecting shaft 601, a pressing block 602, a column 603, a first mushroom top 604 and a second mushroom top 605. The connecting shaft 601 is symmetrically slidably connected to the inside of the sleeve 5, the pressing block 602 is fixedly connected to the end of the connecting shaft 601 that is close to it, the column 603 is fixedly connected to the top of the suction cup 4, the first mushroom top 604 is fixedly connected to the top of the column 603, and the second mushroom top 605 is slidably connected to the outside of the column 603. By fitting the suction cup 4 to the bottom plate and placing the suction cup 4 inside The air inside is discharged outwardly, so that the connection between the sheet body 1 and the floor is realized, and its fixation is greatly improved. When the suction cup 4 needs to be replaced, the column 603 is moved toward the inside of the accommodating groove 3, so that the inclined surface of the pressing block 602 is in contact with the second mushroom top 605, and the column 603 is pulled out again, so that the pressing block 602 clamps the second mushroom top 605, and the second mushroom top 605 is connected to the first mushroom top 604 and merged into a sphere, so that the connecting shaft 601 slides to both sides, the clamping of the pressing block 602 is released, and the disassembly work is completed.
[0029] For further information, see Figure 1 , Figure 2 and Figure 3 In this embodiment, the end of the connecting shaft 601 that is away from the connecting shaft 601 extends to one end of the sleeve 5, and a spring 606 is sleeved on the outside of the connecting shaft 601. The pressing block 602 is designed with an inclined structure. The spring 606 is sleeved on the outside of the connecting shaft 601 and presses against the inner wall of the sleeve 5 to realize the sliding of the connecting shaft 601 in the sleeve 5.
[0030] For further information, see Figure 1 , Figure 2 and Figure 4 In this embodiment, a card slot 101 and a card block 102 are respectively provided on the outside of the sheet body 1 and the anti-slip layer 2, and the card slot 101 and the card block 102 are adapted for use. The card slot 101 connects the card blocks 102 to each other, thereby achieving splicing between multiple groups of sheet bodies 1.

The special-shaped groove 201 is designed in a wavy structure. The surface of the anti-slip layer 2 is coated with a fluorine-containing coating. Through the design of the special-shaped groove 201, the anti-slip layer 2 is divided into uneven surfaces, which increases the friction between the anti-slip layer 2 and the sole of the foot, thereby improving the anti-slip properties of the sheet body 1.

[0035] In this embodiment, the implementation scenario is specifically as follows: by fitting the suction cup 4 to the bottom plate and discharging the air inside the suction cup 4 to the outside, the connection between the sheet body 1 and the floor is achieved, so that its fixation is greatly improved. When the suction cup 4 needs to be replaced, the column 603 is moved toward the inside of the accommodating groove 3, so that the inclined surface of the pressing block 602 is in contact with the second mushroom top 605, and the column 603 is pulled out again, so that the pressing block 602 clamps the second mushroom top 605, and the second mushroom top 605 is connected to the first mushroom top 604 and merged into a sphere, so that the connecting shaft 601 slides to both sides, the clamping of the pressing block 602 is released, and the disassembly work is completed. The card blocks 102 are connected to each other through the card slots 101, so as to achieve multiple groups of sheet bodies. 1 is spliced together, and the anti-skid layer 2 is divided into uneven surfaces by the design of the special-shaped groove 201, so that the friction between the anti-skid layer 2 and the sole of the foot is increased, and the anti-skid property of the sheet body 1 is improved. When the interior of the placement groove 106 is eroded by the liquid, the liquid will flow into the interior of the expansion ball 107. At the same time, the expansion ball 107 will expand, thereby blocking the placement groove 106 to prevent the liquid from entering the lower layer of the sheet body 1 through the placement groove 106. The static electricity generated by friction can be effectively eliminated by the anti-static wire. The flame retardant layer 105 adopts a three-layer composite flame retardant inner layer with good tear strength, crispness and wrinkle resistance. Both aramid and vinylon have excellent flame retardant properties. At the same time, aramid and vinylon can play a synergistic effect, which is helpful to improve the flame retardant effect.
