Technical Field
[0001] The utility model relates to the technical field of plate assembly, in particular to a firmly biting crabapple corner connection structure and a cabinet body. Background Art
[0002] The Begonia Corner is a unique craft in architectural decoration and furniture making, mainly used to make the external corners appear softer. It uses a 45-degree angle-collaring method, but when cutting, it does not completely cut to the glaze surface, but leaves a gap of 2-3 mm to make the external corner part more rounded. The Begonia Corner not only enhances durability and facilitates the construction of beautiful seams, but also improves the overall aesthetics. It is an exquisite choice for decoration. In wooden furniture, whether it is the corner of the wall panel, or the joint between the cabinet drawer and the side panel, or the cabinet door and the side panel, the Begonia Corner craft can be widely used.
[0003] The 45° bevel splicing method is to make a 45° bevel cut on one end of two wooden boards respectively, and the cross-section formed is a right-angle trapezoidal shape. When the two cut surfaces are spliced together, a crabapple angle is naturally formed at the outer corner; the single-board milling type is to only mill a single board, so that the inner side of the board does not need to be edge-sealed, and the joint after splicing forms a crabapple angle. For example, the patent document with announcement number CN220024543U adopts the bevel cutting process; the slot method is to process grooves on two wooden boards respectively, and the part beside the groove is a convex block. When the two wooden boards are spliced vertically, the convex block on the inner side of the right angle of the wooden board is embedded in the groove of the other wooden board. After the wooden boards are spliced, glue or angle codes are usually used to further strengthen the fixation of the two wooden boards. However, in actual applications, the spliced wooden furniture processed by these three methods still has varying degrees of instability.
[0004] Therefore, it is urgent to provide a crabapple corner connection structure and a cabinet with a firm bite to solve the above technical problems. Summary of the invention

[0011] By providing a plurality of mutually matching convex parts, concave parts and concave grooves on the two wooden boards, the bite force between the two boards after splicing can be effectively enhanced. The first wooden board presents an F-shaped outline, and the second wooden board presents a concave outline.
[0012] As a further optimization of the above solution, the bottom widths of the first groove and the second groove are the same.
