Background

The existing furniture products are often formed by mutually assembling a plurality of plates, and the plates are generally connected and fixed by screws in the assembling process of the furniture, so that the installation is troublesome. For example, taking a common cabinet structure as an example, when the existing cabinet is assembled, people often need to use a screwdriver to install and fix connecting pieces such as screws on the bottom plate, the four side plates and the cover plate, so that the bottom plate, the side plates and the cover plate are assembled together, the assembly is time-consuming and labor-consuming, the assembly efficiency is low, and accordingly, the screws are required to be unscrewed one by one when the cabinet is disassembled, and the assembly is inconvenient. Moreover, when the cabinet is fixed by screw connection, the bottom plate, the side plate and the cover plate of the cabinet are often required to be reserved with mounting holes, and the positions of the reserved mounting holes cannot deviate for accurate assembly, otherwise, the phenomenon of mounting in place or even incapable of mounting occurs. Some cabinets are also provided with embedded connectors in the reserved mounting holes, so that the embedded connectors are required to be mounted by adding subsequent production procedures after the board is formed, and the embedded connectors are often mounted by manual operation of workers, so that the working efficiency is low. Although the prior art also discloses a plug-in structure between two plates, the assembly efficiency is improved, but the occlusion degree of the plug-in structures is not high, the structure reliability and stability are required to be further improved, and in addition, the contact area of the plug-in positions of the two plates is not large enough, so that the waterproof performance is poor. In view of the foregoing, there is a need for further improvements in existing board connecting structures.

Preferably, the straight arm and the circumferential side face are perpendicular to each other.

Preferably, the crank arm is bent toward one side or both left and right sides of the direction in which the straight arm extends.

The crank arms may take a variety of different configurations, preferably the crank arms are S-shaped or Z-shaped or U-shaped or C-shaped or V-shaped or W-shaped.

In order to enable the first plate and the second plate to be mutually inserted in place, one end of the strip-shaped groove is provided with an opening, and the other end of the strip-shaped groove is closed.

Preferably, the strip-shaped groove is adjacent to the edge of the second plate material and is arranged along the length direction of the edge.

Further preferably, the first plate and the second plate are perpendicular to each other in a state that the first plate and the second plate are inserted into each other. Thus, the above-mentioned plug-in structure can be used between two adjacent plates of the rectangular box body.

Compared with the prior art, the utility model has the advantages that: the first plate and the second plate of the plate inserting structure adopt the inserting structure of the strip-shaped convex ribs and the strip-shaped grooves, the strip-shaped convex ribs are composed of straight arms and crank arms extending outwards from the outer ends of the straight arms, therefore, the contact surface of the strip-shaped convex ribs and the strip-shaped grooves can be increased, the occlusion degree is good, the structure is stable, the water-proof performance of inserting positions is improved, the first plate and the second plate are not required to be connected through connecting pieces when being inserted, the assembly is very convenient and quick, and in addition, the plate inserting structure is wide in application range and particularly suitable for connection between two adjacent side plates of a cabinet.

The strip-shaped ribs 11 and the strip-shaped grooves 21 which can be mutually spliced are respectively formed on the first plate 1 and the second plate 2, so that the first plate 1 and the second plate 2 can only relatively move along the splicing direction. The strip-shaped ribs 11 of the present embodiment are disposed on one of the circumferential side surfaces 12 of the first plate 1, the strip-shaped grooves 21 are disposed on the inner side wall of the second plate 2, and the strip-shaped grooves 21 are adjacent to the edge of the second plate 2 and are disposed along the length direction of the edge. The shape of the strip-shaped groove 21 is matched with that of the strip-shaped convex rib 11, one end of the strip-shaped groove 21 is opened, and the other end of the strip-shaped groove is closed, so that the first plate 1 and the second plate 2 can be conveniently inserted in place.

One of the circumferential side surfaces 12 of the first plate 1 extends outwards to form a straight arm 111, the straight arm 111 is perpendicular to the circumferential side surface 12, the outer end of the straight arm 111 extends outwards to form a crank arm, and the straight arm 111 and the crank arm form a strip-shaped convex rib 11 together. In this embodiment, the S-shaped crank 112 is used as the crank, and at this time, as shown in fig. 5, the S-shaped crank 112 is bent toward both left and right sides in the extending direction of the straight arm 111. After the strip-shaped convex ribs 11 adopt the S-shaped crank arms 112, the contact area between the strip-shaped convex ribs 11 and the strip-shaped grooves 21 is larger, so that on one hand, the engagement degree of the first plate 1 and the second plate 2 can be improved, the splicing structure is more stable and reliable, and on the other hand, along with the increase of the contact area, the waterproof effect of the splicing position of the first plate 1 and the second plate 2 is also facilitated.

In this embodiment, the first plate 1 is a bottom plate of a cabinet, the second plate 2 is a side plate of the cabinet, and when the first plate 1 and the second plate 2 are inserted into each other, the first plate 1 is placed horizontally, then the second plate 2 is placed in a vertical position, and the bar-shaped ribs 11 are inserted backward from the open ends of the bar-shaped grooves 21 until the rear ends of the bar-shaped ribs 11 abut against the closed ends of the bar-shaped grooves 21, so that the first plate 1 and the second plate 2 are inserted into each other.

The board plug-in structure can also be applied to plug-in cooperation between other adjacent boards of the cabinet, for example, the first board 1 is a right side board of the cabinet, the second board 2 is a front side board of the cabinet, and when the right side board and the front side board are assembled by adopting the plug-in structure, no connecting piece is needed, so that the installation is very convenient and quick, and correspondingly, the disassembly is also very convenient. Of course, the connection structure between the left side plate and the front side plate, and the connection structure between the left side plate and the rear side plate, and the connection structure between the right side plate and the rear side plate may also adopt the plate plugging structure in the present embodiment.
