In summary, in the connecting device provided in this embodiment, through the combination of the buckle 13 on the first connecting member 1 and the sliding slot 23 and the fastening hole 24 on the second connecting member 2, the buckle 13 is inserted from the sliding slot 23 and slides along the length direction (the horizontal direction shown in fig. 3) of the sliding slot 23, so as to slide and fasten in the fastening hole 24; the buckle 13 clamped in the clamping hole 24 is limited by the elastic limiting sheet 3, so that the buckle 13 is prevented from automatically sliding back into the chute 23, namely, the buckle 13 and the chute 23 are arranged and connected by clamping, and the installation can be realized without tools during installation, so that the tools are not needed; meanwhile, the elastic limiting piece 3 can prevent the first connecting piece from sliding back and falling off, so that the purposes of easy installation and no self-falling off are achieved, and the installation firmness is ensured; during the dismantlement, strike with instruments such as hammers and treat the connecting piece, under appropriate effort, the spacing piece of elasticity 3 elastic deformation is to stretching forward the bending, and buckle 13 can return and slide to in the spout 23 to can slide between two treating the connecting piece and drop, realize can carrying out the purpose of dismantling under certain exogenic action, solve current furniture panel and connect the problem that can't dismantle or drop easily. In addition, the connecting device also has the following technical effects:

firstly, the first connecting piece 1 and the second connecting piece 2 in the connecting device do not limit the thickness of the piece to be connected when the piece is a plate, as long as the thickness is larger than the thickness of the corresponding first connecting piece 1 and second connecting piece 2, compared with the prior art, the plate with different thicknesses has different assembly and disassembly precision, so that the application range of the connecting device is expanded by adopting different connecting pieces;

the second connecting piece 1, the first connecting piece 2 and the second connecting piece are respectively embedded in the two pieces to be connected, so that the fully-concealed installation is realized, and the installation attractiveness is improved;

thirdly, the furniture board can be applied to furniture boards or bathroom boards, and the furniture with a three-dimensional structure can be disassembled into the boards, so that the transportation is convenient, and the transportation cost is reduced;

the fourth connecting piece 1 and the second connecting piece 2 can be pre-installed on the piece to be connected, and the furniture does not need to be positioned and fixed again when being assembled, so that tool-free installation and disassembly can be realized;

fifth, the longitudinal section of the second connecting piece 2 perpendicular to the second exposed surface 22 is of an inverted trapezoidal structure, and the cross section of the second connecting piece 2 perpendicular to the second exposed surface 22 is of an inverted trapezoidal structure, so that when the second connecting piece 2 is pre-embedded to a second to-be-connected piece, the second to-be-connected piece is pushed into the sinking groove, scraps formed when the second to-be-connected piece is grooved are extruded inside, the surface of the second to-be-connected piece 2 is ensured to be clean, and the attractiveness is further improved;

sixth, first connecting portion 32, the slope gradient of spacing portion 33 is different, especially, the angle of inclination of first connecting portion 32 is less than the angle of inclination of spacing portion 33, first connecting portion 32's compressive force is less, make the deformation effort of pushing down less, it is easier and laborsaving to make buckle 13 insert down in place and slide to the card in-hole 24, the spacing power that spacing portion 33 produced is great, spacing power to buckle 13 who lies in card in-hole 24 is great, make buckle 13 be difficult to return by oneself and slide and withdraw from, both drop when further avoiding using, and spacing portion 33 slope sets up and has guaranteed again can realize the backsliding of buckle 13 under the exogenic action, can realize the deformation of spacing portion 33 through external force when dismantling promptly and realize dismantling in order to withdraw from.

Invisible connection structure of plates:

the embodiment also provides a plate invisible connecting structure; this stealthy connection structure of panel includes: two plates; wherein, the two plates are connected through the connecting device; that is to say, the two pieces to be connected are both plates, so that the connection between the two plates is realized through the connecting device. The specific implementation process of the connection device may be as described above, and this embodiment is not described herein again.

Due to the fact that the connecting device has the effect, the plate connecting structure with the connecting device also has the corresponding technical effect.

Furniture:

the embodiment also provides furniture; the furniture is provided with the invisible connecting structure for the plates. The specific implementation process of the invisible plate connecting structure can be described by referring to the above description, and the detailed description is omitted here.

Because the invisible connecting structure of the board has the effects, the furniture with the invisible connecting structure of the board also has corresponding technical effects.

Of course, the connecting device and the invisible plate connecting structure can be applied to furniture, bathroom cabinets and other practical fields.
