DETAILED DESCRIPTION

The utility model is further described below in conjunction with the accompanying drawings.

Please refer to Figures 1 to 5. The utility model provides an embodiment: a honeycomb aluminum plate invisible connection structure, including a connecting piece 1, a connecting block 2 and a sleeve 3, the connecting piece 1 is fixed in the sleeve 3, the upper surface of the connecting block 2 is provided with a first inclined groove 4, the lower surface of the connecting block 2 is provided with a second inclined groove symmetrical to the first inclined groove 4, the first inclined groove 4 and the second inclined groove are provided with a limiting groove 5 that can be engaged with the connecting piece 1 on one side of the lowest part of the bottom of the groove, the connecting block 2 is provided with a first slot 8 on both sides of the upper surface, the bottom of the first slot is fixed with a first limiting card plate 10, and the outer surface of the sleeve 3 is provided with a limiting card. The honeycomb panel is provided with holes of the same size as the shaft sleeve 3 and the connecting block 2, and the shaft sleeve 3 and the connecting block 2 are respectively installed in the corresponding holes. The shaft sleeve 3 and the connecting block 2 are limited and fixed in the hole of the honeycomb panel by the limiting clamp on the shaft sleeve 3 and the limiting clamp plate on the connecting block 2. Then, the connecting member 1 and the connecting block 2 are fixed by sliding the telescopic head in the connecting member 1 from the inclined groove into the limiting clamp groove 5, so that the connection between the honeycomb panels can be achieved without fixing with screws or bolts.

Please continue to refer to FIG. 2 , in one embodiment of the present invention, the width of the first limit card plate 10 gradually increases from bottom to top. The width of the first limit card plate 10 gradually increases from bottom to top. The first limit card plate 10 is elastic and will not affect the placement into the corresponding hole. After being placed in, it will stretch due to the elasticity to limit and fix.

Please continue to refer to Figures 1 and 2. In one embodiment of the present invention, the bottom of the first slanted groove 4 gradually approaches the upper surface of the connecting block 2 from left to right, and the bottom of the second slanted groove gradually approaches the lower surface of the connecting block 2 from left to right. The first slanted groove 4 can guide the movement of the connecting member 1, making it more convenient to fix the connecting member 1 and the connecting block 2.

Please continue to refer to Figures 1 and 3. In one embodiment of the utility model, the position-limiting clamp includes a second slot 11 opened on both sides of the shaft sleeve 3, and an L-shaped second position-limiting clamp 12 is fixed on the inner side wall of the second slot 11.
