Detailed ways

The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the implementations. example.

1-3, a plywood with high bonding strength includes a center layer 6, the upper and lower surfaces of the center layer 6 are respectively pasted with an upper plate layer 5 and a lower plate layer 7, the center layer 6, the upper plate layer 5 and the lower plate layer There are a plurality of second through holes 4 between the plate layers 7, and the distance between the adjacent second through holes 4 is 30-40cm, which can strengthen the relationship between the upper plate layer 5, the central layer 6 and the lower plate layer 7. The strength of the connection between the two, thereby improving the stability of the plywood.

A surface of the upper plate layer 5 and the lower plate layer 7 is provided with a first through hole 2 that communicates with the second through hole 4, and a connecting component 3 is installed between the first through hole 2 and the second through hole 4, and is connected to the second through hole 4. The assembly 3 includes a central shaft 34 located in the second through hole 4, and both ends of the central shaft 34 are provided with push grooves 33. The connecting assembly 3 also includes a sealing plate 31 located inside the first through hole 2. The extruding blocks 32 are fixedly installed on the sides, and the extruding blocks 32 are located inside the pushing grooves 33, and the structure is simple. It is squeezed and clamped with the lower board layer 7 to realize the effect of tightening the upper board layer 5, the center layer 6 and the lower board layer 7, and prevent the upper board layer 5, the center layer 6 and the lower board layer 7 from being separated from each other.

Limiting grooves 9 are provided on both sides of the upper board layer 5 and the lower board layer 7, and a U-shaped frame 8 is installed between the corresponding two limiting grooves 9. The U-shaped frame 8 is an integral molding structure with high structural strength. The use effect is good, and the connection is effectively strengthened.

The upper and lower parts of the inner side of the U-shaped frame 8 are fixedly installed with fixing blocks 81 , and the interior of the limiting groove 9 is provided with a fixing groove 91 . The fixing blocks 81 are located inside the fixing grooves 91 , and the upper and lower surfaces of the U-shaped frame 8 One surface of the layer 5 and the lower plate layer 7 is located on the same plane, which can further strengthen the connection strength between the upper plate layer 5, the center layer 6, and the lower plate layer 7, thereby preventing the upper plate layer 5, the center layer 6, the lower plate layer. The layers 7 are directly separated from each other.

A decorative layer 1 is attached to one side of the upper board layer 5 and the lower board layer 7 .

Working principle: When using, first stick the upper board layer 5, the center layer 6 and the lower board layer 7 together with glue, then process the second through hole 4 and the first through hole 2, and then insert the center shaft 34 into the second through hole.
