Description

TECHNICAL FIELD

[0001] The utility model relates to furniture technical field, especially a wooden mortise and tenon bookcase. BACKGROUND

[0002] As an important part of home life, bookcases not only have storage functions, but also play a role in decorating space. With the improvement of people's living standards, the design and quality requirements of bookcases are getting higher and higher, both aesthetic and practical, and also need to meet the standards of environmental protection and durability. Traditional bookcases are mostly connected by screws, nails or adhesives, although these connection methods are simple and easy to produce, but there are some problems. Screws and nails often cause damage to wood, leading to wood cracking, loosening and other conditions, affecting the service life; adhesives are prone to failure in environments with large temperature and humidity changes, and may release harmful substances, affecting environmental health. Therefore, the traditional manufacturing process cannot meet the modern home's demand for environmental protection, durability, aesthetics and other aspects.

[0003] As part of traditional woodworking techniques, the mortise and tenon process is a connection method that does not rely on metal parts or glue, which can fully preserve the natural texture of wood and has high structural stability and aesthetics. However, the traditional mortise and tenon process requires skilled handcraft, and the processing efficiency is low, which is difficult to meet the requirements of modern production. In addition, the traditional mortise and tenon structure has limitations in flexibility and disassembly, especially in bookcases, a type of home product, users' individualized needs for the size, shape and layout of bookcases are increasing.

[0004] Therefore, there is an urgent need for an improved wooden bookcase that not only inherits the advantages of the mortise and tenon process, but also solves the problems of low processing efficiency and inflexible connection in traditional processes, improves the modularity and disassembly convenience of bookcases, and can meet the diversified needs of modern homes for function and design.

The base board has positioning bosses at its four corners, and each positioning boss has three slots arranged in an L-shape for inserting a first insert rod. The middle slot, furthest from the corner of the base board, is the first slot, and the other two slots are second slots. A third slot is located near the corner of the base board, and a second insert rod is inserted into the third slot. Side panels, insert plates, and fixing plates are symmetrically arranged on the left and right sides of the base board. Each side panel includes a first side panel located inside the positioning boss on the same side, and a second side panel inserted between the first and second slots of the positioning boss on the same side. The side panel, and the third side panel located outside the positioning boss on the same side, the insert plate is perpendicular to the side panel, located between the first slot and the second slot, and is inserted and connected to the side panel on the same side. The fixing plate is located above the side panel and the insert plate, and is provided with a first insertion hole and a second insertion hole for the first insertion rod and the second insertion rod to be inserted. The lower plate is provided with a first groove for the fixing plate to be inserted and connected. Two drawers are arranged in the space between the first side panels. The four corners of the lower plate are connected to the middle plate through the first support frame. The middle plate is connected to the top plate through the second support frame. The adjacent first support frames and the adjacent second support frames form a partition for placing books. The panel of the top plate forms a display stand.

[0007] Furthermore, the third side plate has L-shaped notches at both ends, and the insert plate has a vertical groove near the outer end, and the two are snapped together.

[0008] Furthermore, the lower panel has a cross-shaped groove at its center, into which a support plate is inserted and connected. The upper end of the support plate rests against the back of the middle panel, and the support plate and the first support frame form a partition for placing books.

[0009] Furthermore, the second insert extends through into the first support frame, with its upper end abutting against the back of the middle layer plate.

[0010] Furthermore, the middle layer has a central support column, the upper end of which rests against the back of the upper layer.

[0011] Furthermore, the interiors of the first support frame and the second support frame are vertically connected, and they are connected to the adjacent plates by slots and / or protrusions.

[0012] Furthermore, both the first support frame and the second support frame include two vertical inner side plates and two outer side plates that extend outward from bottom to top. The middle layer plate and the upper layer plate gradually extend and expand outward relative to the lower layer plate.
