Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the protection scope of the present utility model.

[0023] The following gives specific embodiments.

[0024] Such as Figures 1 to 3As shown in the figure, an anti-collision EPS foam board according to an embodiment of the present utility model includes an EPS foam board body 1; two EPS foam board bodies 1 are symmetrically arranged; a connecting piece 2 is provided outside the EPS foam board body 1; a fixing bolt 3 is threadedly connected inside the connecting piece 2, and the fixing bolt 3 is threadedly connected at an internal position of the EPS foam board body 1; a plurality of sliding seats 4 are fixedly connected inside the EPS foam board body 1, and the sliding seats 4 are regularly arranged in a linear array inside the EPS foam board body 1; a sliding rod 5 is slidably connected inside the sliding seat 4, and one end of the sliding rod 5 contacts the inner side wall of another EPS foam board body 1; a return spring 6 is fixedly connected between the bottom of the sliding rod 5 and the inner side wall of the sliding seat 4; during operation, when the EPS foam board body 1 needs to be used, the two EPS foam board bodies 1 can be spliced together, and the two EPS foam board bodies 1 are fixed through the connecting piece 2 and the fixing bolt 3. After the fixing is completed, by arranging the sliding seat 4 and the sliding rod 5 between the two EPS foam board bodies 1, and buffering the impact received by the sliding rod 5 through the return spring 6, the anti-collision ability of the EPS foam board body 1 can be stronger. At the same time, hydraulic oil can be filled inside the sliding rod 5 to dampen and relieve the impact force received by the sliding seat 4, so that the anti-impact ability of the EPS foam board body 1 can be stronger. At the same time, by fixing the EPS foam board body 1 through the connecting piece 2 and the fixing bolt 3, the replacement of the EPS foam board body 1 can be more convenient.

[0025] As Figures 3 to 4 shown, a limiting block 7 is fixedly connected to the end of the sliding rod 5; the limiting block 7 is slidably connected at an internal position of the sliding rod 5; during operation, when the sliding rod 5 slides inside the sliding seat 4, by arranging the limiting block 7 at the end of the sliding rod 5 to block the sliding of the sliding rod 5, the sliding of the sliding rod 5 can be blocked, so that the situation where the sliding rod 5 is disengaged from the sliding seat 4 can be effectively avoided, and the effect of connecting the two EPS foam board bodies 1 by the sliding seat 4 and the sliding rod 5 can be better.

[0026] As Figure 2 shown, two support nets 8 are provided inside the EPS foam board body 1, and the two support nets 8 are respectively arranged at positions corresponding to the ends of the sliding seat 4 and the sliding rod 5; the side wall of the support net 8 contacts the inner side wall of the EPS foam board body 1; during operation, when the EPS foam board body 1 is supported by the sliding seat 4 and the sliding rod 5, by arranging the support nets 8 at the ends of the sliding seat 4 and the sliding rod 5, the contact area between the sliding seat 4, the sliding rod 5 and the EPS foam board body 1 can be larger, so that the effect of supporting the EPS foam board body 1 by the sliding seat 4 and the sliding rod 5 can be better, and the situation where the EPS foam board body 1 is deformed and sunken can be effectively avoided.

[0027] As Figure 4As shown, a plurality of liquid passing holes 9 are formed inside the limit block 7, and the liquid passing holes 9 are arranged regularly in a circumferential array inside the limit block 7; a blocking gasket 10 is fixedly connected inside the liquid passing hole 9, and the opening of the blocking gasket 10 corresponding to the bottom of the limit block 7 is smaller, and the opening corresponding to the top of the limit block 7 is larger; during operation, when the limit block 7 slides inside the sliding seat 4, by forming the liquid passing holes 9 inside the limit block 7 and arranging the blocking gasket 10 inside the liquid passing holes 9, when the impact force on the sliding rod 5 is too large, it is likely to cause the instantaneous pressure on the hydraulic oil inside the sliding seat 4 to be too large, making it easy for the hydraulic oil to cause deformation and damage inside the sliding seat 4.

[0028] As Figures 3 to 4 shown, a plurality of guide grooves 11 are formed on the side wall of the limit block 7; the guide grooves 11 are arranged regularly in a circumferential array inside the limit block 7; a plurality of guide blocks 12 are fixedly connected inside the sliding seat 4; the guide blocks 12 and the guide grooves 11 are arranged in correspondence; during operation, when the limit block 7 slides inside the sliding seat 4, by restricting the sliding of the guide block 12 in the guide groove 11, it is possible to make the limit block 7 less inclined when sliding, making the sliding of the limit block 7 more stable.

[0029] As Figure 5 shown, a pushing block 13 is slidably connected inside the support net 8; a fixing spring 14 is fixedly connected to the bottom of the pushing block 13; the bottom end of the fixing spring 14 is fixedly connected to the inner side wall of the support net 8; during operation, when the support net 8 is squeezed by the fixing bolt 3 to fix the EPS foam board body 1, by arranging the fixing spring 14 inside the support net 8 to push the pushing block 13, it is possible to make the pressure between the threads of the fixing bolt 3 and the connecting piece 2 greater, making the frictional force between the fixing bolt 3 and the connecting piece 2 greater, so that the fixing effect of the fixing bolt 3 on the connecting piece 2 and the EPS foam board body 1 is better.

[0030] During operation, when the EPS foam board body 1 needs to be used, two EPS foam board bodies 1 can be spliced together, and the two EPS foam board bodies 1 are fixed by the connecting piece 2 and the fixing bolt 3. After the fixing is completed, by arranging the sliding seat 4 and the sliding rod 5 between the two EPS foam board bodies 1 and buffering the impact on the sliding rod 5 through the return spring 6, the anti-collision ability of the EPS foam board body 1 can be made stronger. At the same time, hydraulic oil can be filled inside the sliding rod 5 to reduce the impact force on the sliding seat 4, so that the anti-impact ability of the EPS foam board body 1 can be made stronger. At the same time, by fixing the EPS foam board body 1 with the connecting piece 2 and the fixing bolt 3, the replacement of the EPS foam board body 1 can be made more convenient.

[0031] When the sliding rod 5 slides inside the sliding seat 4, by providing a limit block 7 at the end of the sliding rod 5 to block the sliding of the sliding rod 5, the sliding of the sliding rod 5 can be blocked, thereby effectively avoiding the situation where the sliding rod 5 disengages from the sliding seat 4, and enabling the sliding seat 4 and the sliding rod 5 to better connect the two EPS foam plates 1.

[0032] When the EPS foam plate 1 is supported by the sliding seat 4 and the sliding rod 5, by providing a support mesh 8 at the ends of the sliding seat 4 and the sliding rod 5, the contact area between the sliding seat 4, the sliding rod 5 and the EPS foam plate 1 can be made larger, thereby enabling the sliding seat 4 and the sliding rod 5 to better support the EPS foam plate 1, and effectively avoiding the situation where the EPS foam plate 1 is deformed and dented.

[0033] When the limit block 7 slides inside the sliding seat 4, by providing a liquid passage hole 9 inside the limit block 7 and a blocking gasket 10 inside the liquid passage hole 9, when the impact force on the sliding rod 5 is too large, it is likely to cause the instantaneous pressure on the hydraulic oil inside the sliding seat 4 to be too large, making the hydraulic oil likely to cause deformation and damage inside the sliding seat 4.

[0034] When the limit block 7 slides inside the sliding seat 4, by restricting the sliding of the limit block 7 in the guide groove 11 through the guide block 12, the situation where the limit block 7 is inclined less during sliding can be made, making the sliding of the limit block 7 more stable.

[0035] When the support mesh 8 is squeezed by the fixing bolt 3 to fix the EPS foam plate 1, by providing a fixing spring 14 inside the support mesh 8 to push the push block 13, the pressure between the threads of the fixing bolt 3 and the connecting piece 2 can be made larger, making the frictional force between the fixing bolt 3 and the connecting piece 2 larger, thereby enabling the fixing bolt 3 to better fix the connecting piece 2 and the EPS foam plate 1.
