Buckle type connecting structure of solid wood or raw wood furniture

Abstract

The invention discloses a buckle type connecting structure of solid wood or raw wood furniture. The buckle type connecting structure comprises a first furniture sheet material, a second furniture sheet material and a connecting piece which are connected correspondingly, wherein the connecting piece consists of two parts, namely a buckling plate and buckling screws; each buckling screw comprises a bolt and an embedded nut; the buckling plate comprises two fixed parts positioned at two ends, and a convex connecting part positioned in the middle; a clamping groove is formed in the connecting part, and is arranged in an inclined slope manner; the height is gradually decreased from the inlet end to the buckling end by taking the plane of the two fixed parts as basic reference. The buckle type connecting structure ensures the high-grade quality of solid wood and raw wood furniture, and is simple in structure and convenient to install, use and detach, thus the labor intensity is alleviated and the labor cost is reduced, the problems of great processing difficulty and low production efficiency in the traditional process are solved, the limitation of bearing capacity and stability for the three-in-one connecting piece is broken through, and a foundation is laid for realizing factory scale production of solid wood and raw wood furniture.

Description

technical field [0001] The invention relates to a connecting device for furniture. Background technique [0002] With the improvement of people's living standards, the level of furniture demand is also increasing. Solid wood finger joint boards, log splicing boards, log materials and other high-quality raw materials are more and more popular among the public. However, most of the high-end solid wood and log furniture on the market are made according to traditional techniques, and the parts are usually connected by mortise and tenon structure, which is slow, technically difficult, labor costs are too high, and more glue is used for bonding, which is not environmentally friendly. It is inconvenient to disassemble and assemble, and it is easy to cause damage to the furniture during the transportation process. It is difficult to meet the requirements of firmness and durability when making small pieces. [0003] Although the three-in-one connector (also known as the eccentric co...

AI Technical Summary

Problems solved by technology

However, most of the high-end solid wood and log furniture on the market are made according to traditional techniques. The parts are usually connected by mortise and tenon structure. The speed is slow, the technology is difficult, the labor cost is too high, and most of them are glued together, which is not environmentally friendly.

It is inconvenient to disassemble and assemble, and it is easy to cause damage to the furniture during the transportation process. It is difficult to meet the requirements of firmness and durability when making small pieces.

[0003] Although the three-in-one connector (also known as the eccentric connector) can replace the mortise and tenon structure in the traditional process, but: ①The three-in-one connector is generally only suitable for board combinations of recycled materials such as medium density boards, high density boards, and particle boards. Board / board connection in furniture: Recycled material boards have extremely poor elasticity due to their bonded structure, especially when the side is stressed, it is very easy to break, and the nail holding force is small

The wood hardness of solid wood and logs is relatively high, which is 3 to 5 times the hardness of recycled materials, and the stress is large; when the three-in-one connector is used on solid wood and log furniture, the eccentric wheel with a tight rotating belt is easy to slide and reverse, and it will loosen and fall off , resulting in loose board / board connection, especially after repeated disassembly and assembly, which seriously affects the firmness and stability of the connection

[0004] ② For furniture using three-in-one connectors, the nuts of the eccentric wheels at the joints must be exposed. It is acceptable to use it in panel furniture, but it is used on high-grade solid wood and log furniture. The exposed nuts completely destroy the quality of the finished product. , greatly reducing the grade or grade of finished products

[0005] ③ Three-in-one connectors have high requirements for installation and production, and the finished product cannot be assembled if the error exceeds ±0.1mm, and it is prone to problems such as uneven installation force of the finished plate

[0006] ④ Recycled material board has no obvious directionality and is evenly stressed

However, solid wood and logs have obvious directionality, and they can only be drilled in the direction of the wood grain in a blink of an eye. Using three-in-one connectors to make furniture is easy to deform

Moreover, the use of three-in-one connectors can only be painted after the installation is completed, and the moisture absorption channel of the wood cannot be closed in time, causing the wood to easily absorb moisture and expand and deform
