Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0031] Reference Figure 1 - Figure 2The utility model provides an embodiment: a plywood with sound insulation performance, including plywood 1 and plywood 2 12, plywood 2 12 is slidably connected to the right side of plywood 1, plywood 1 and plywood 2 12 are fixedly connected to two mounting rods 2 on their left sides, the mounting rods 2 are used to conveniently connect the two plywoods, plywood 1 and plywood 2 12 are slidably connected to two insertion rods 4 on their right sides, the outer periphery of the insertion rod 4 is fixedly connected to a limiting plate 5, the top of the limiting plate 5 is fixedly connected to a compression spring 6, the insertion rod 4 The limit plate 5 is connected with the limit plate 5, and can drive the limit plate 5 to move together when the plug rod 4 moves, and the compression spring 6 is used to provide elastic support. When the limit plate 5 moves with the plug rod 4, the compression spring 6 will be squeezed, and when the plug rod 4 loses its active pulling force, the compression spring 6 will also correspondingly lose the squeezing force of the limit plate 5, thereby generating a thrust to push the limit plate 5 to move, and then the limit plate 5 can drive the plug rod 4 to move. A slot 8 is provided inside the mounting rod 2, and a limiting groove 7 is provided inside the plywood 1. The inner surface of the plywood 1 and the plywood 2 12 are connected to each other. The bottom of the plug rod 4 is embedded in the slot 8, and the bottom of the plug rod 4 is embedded in the slot 8 of the installation rod 2, so that the plug rod 4 can limit the installation rod 2, so that the installation rod 2 is located inside the plywood, thereby realizing the connection and cooperation between the two plywood boards, and the limiting plate 5 is slidably connected to the inside of the limiting groove 7, and the limiting groove 7 is used to accommodate the sliding of the limiting plate 5, the diameter of the limiting plate 5 is equal to the diameter of the limiting groove 7, and the length of the limiting groove 7 is the sliding range of the limiting plate 5, so that the plug rod 4 will not Slide out the interior of the plywood, and the two installation rods 2 on the left side of the plywood second 12 are slidably connected to the right side of the interior of the plywood one 1. The two installation rods 2 on the left side of the plywood second 12 are inserted into the interior of the plywood one 1, so that the plywood one 1 can be connected with the plywood two 12. The top of the insertion rod 4 is rotatably connected with the pull rod 3. The pull rod 3 is used for the operator to pull the insertion rod 4 to move, and grooves are provided on the surfaces of the plywood one 1 and the plywood two 12 for conveniently placing the pull rod 3, so that the pull rod 3 is concealed and will not be easily damaged.
[0032] Reference Figure 1 and Figure 3The sound insulation component includes two corrugated plates 9, which are respectively fixedly connected to the upper and lower sides of the inside of the plywood 1, and the two corrugated plates 9 are fixedly connected with sound-absorbing foams 10 on the opposite sides, and the two sound-absorbing foams 10 are fixedly connected with fiberboards 11 on the opposite sides. The corrugated plates 9 are made of polycarbonate material, and the corrugated plates 9 are made of polycarbonate material and have the function of dispersing and absorbing sound wave energy. Placing the corrugated plates 9 on the outermost side of the plywood 1 can achieve the effect of the first layer of sound wave dispersion.

After releasing the pull rod 3, the insertion rod 4 loses the active pulling force, so that the compression spring 6 will also lose the extrusion of the limit plate 5, and then a reset movement is generated. The reset movement of the compression spring 6 will generate a thrust to push the limit plate 5 to move, and then the insertion rod 4 is inserted into the slot 8 opened by the installation rod 2, so that the insertion rod 4 forms a limit on the installation rod 2, so that plywood 1 and plywood 2 12 are assembled and connected. When separating plywood 1 and plywood 2 12, it is only necessary to pull the insertion rod 4 to move the insertion rod 4 so that the insertion rod 4 slides out from the inside of the installation rod 2.
