Description
Technical Field
The utility model relates to a mortise and tenon joint structure especially relates to a cylinder right angle joggle structure.
Background
The ancient Chinese building is built by main components such as upright posts, cross beams, purlins and the like in a structural mode that timber and tiles are used as main building materials and a wood frame structure is used as a main structural mode, and joints among the components are matched by mortise and tenon joints to form a frame with high elasticity. The tenon-and-mortise work is a concave-convex combination connection mode adopted on two wood members, and the protruding part is called a tenon (or tenon); the concave part is called as mortise (or mortise, mortise), and the tenon and the mortise are occluded to play a role in connection. This is the main structure mode of ancient Chinese buildings, furniture and other wooden appliances. The tenon-and-mortise structure is the combination of tenon and mortise, is the ingenious combination of more and less, high and low, long and short between the wood pieces, and can effectively limit the twisting of the wood pieces to all directions. The most basic mortise and tenon structure is composed of two components, wherein a tenon of one component is inserted into a mortise of the other component, so that the two components are connected and fixed. The part of the tenon extending into the mortise is called the tenon, and the rest part is called the shoulder. The tenon-and-mortise structure is widely applied to buildings and furniture, and shows the close relationship between the furniture and the buildings. After the tenon-and-mortise structure is applied to house construction, although each component is thinner, the tenon-and-mortise structure can bear huge pressure on the whole. The structure is not strong in the individual but combined with each other to support each other, and the structure becomes the basic mode of the offspring building and the middle furniture.
At present, most furniture such as existing chairs and tables are fixedly connected by hardware or welding and the like, and the connection mode is convenient to install and does not need to spend a large amount of time on wood to process connection parts such as tenons and the like. However, the desk, chair and furniture which are fixedly connected by using hardware and the like have the problems that the shapes of parts of connecting pieces are easy to distort and deform along with the lapse of the using time and the strength, so that the parts of the structures of the desk, chair and furniture are staggered, for example, the parts of the structures are distorted and deformed by connecting iron nails and hinges, and the relative rotation is caused between the connecting structures; secondly, the metal connecting piece is easy to corrode and oxidize, so that the connecting structure is scattered due to corrosion and fatigue of the connected metal of the desk, chair and furniture; therefore, aiming at the problems, the existing tenon-and-mortise structure technical foundation in China is combined, and if the tenon-and-mortise structure technical foundation can be better applied to the manufacture of the existing furniture, the tenon-and-mortise structure has great prospect.
