BRIEF DESCRIPTION OF THE DRAWINGS

[0012] Figure 1 It is a schematic diagram of the utility model. DETAILED DESCRIPTION

[0013] The following is a further description of the specific implementation of the present invention in conjunction with the accompanying drawings and embodiments. The following embodiments are only used to more clearly illustrate the technical solution of the present invention, and cannot be used to limit the protection scope of the present invention.

[0014] The technical solution specifically implemented in this utility model is:

[0015] like Figure 1 As shown, a green and environmentally friendly composite board comprises a support frame 1 and a filling core layer 2 arranged inside the support frame 1;

[0016] The two ends of the support frame 1 are respectively a first connecting surface 3 and a second connecting surface 4, the first connecting surface 3 is provided with a groove 5, the second connecting surface 4 is provided with two elastic plates 6 for being inserted into the groove 5, and the opposite outer sides of the two elastic plates 6 are respectively provided with a plurality of anti-falling teeth 7, and the two opposite groove walls of the groove 5 are respectively provided with a plurality of tooth grooves 8 corresponding to the anti-falling teeth 7, and the anti-falling teeth 7 are used to engage with the corresponding tooth grooves 8.

[0017] Furthermore, a positioning protrusion 9 is provided at the bottom of the groove 5 , and the positioning protrusion 9 is provided with a positioning hole 10 ; and the second connecting surface 4 is provided with a positioning column 11 for being inserted into the positioning hole 10 .

[0018] Furthermore, the second connection surface 4 is provided with two shielding plates 12 , the two elastic plates 6 are located between the two shielding plates, and the opposite outer sides of the two shielding plates 12 are flush with the two side surfaces of the support frame 1 .

[0019] Furthermore, two sides of the filling core layer 2 are respectively bonded to the inner wall of the support frame 1 through the formaldehyde-free adhesive layer 13 .

[0020] Furthermore, the filling core layer 2 is a heat insulation layer.

[0021] Furthermore, the support frame 1 is a metal frame.

[0022] When two adjacent composite sheets are spliced, the two elastic plates 6 of one of the composite sheets are inserted into the groove 5 of the other composite sheet. During this process, the anti-falling teeth 7 on the elastic plate 6 will be squeezed by the groove wall of the groove 5, causing the two elastic plates 6 to elastically deform inward. When the shielding plate 12 of one of the composite sheets abuts against the first connecting surface 3 of the other composite sheet, the elastic plate 6 is inserted into place. At this time, the elastic plate 6 will be elastically reset, so that the anti-falling teeth 7 are meshed with the corresponding tooth grooves 8, completing the stable connection of the two composite sheets. The shielding plate 12 is provided to shield the elastic plate 6 and to make the surface of the spliced ​​composite sheet smooth. In addition, during the splicing process of the two composite sheets, the positioning column 11 of one of the composite sheets will be drawn into the positioning hole 10 of the other composite sheet to achieve the positioning between the two composite sheets.

[0023] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principle of the present invention. These improvements and modifications should also be regarded as the protection scope of the present invention.
