Description

Technical Field

[0001] The utility model relates to the technical field of connection structures, in particular to a detachable mortise and tenon structure. Background Art

[0002] The mortise and tenon structure is a combination of tenons and mortises. It is an ingenious combination of more and less, high and low, long and short between wooden pieces, which can effectively limit the twisting of wooden pieces in all directions. The most basic mortise and tenon structure consists of two components, one of which has a tenon inserted into the mortise of the other, so that the two components are connected and fixed. The part of the tenon that extends into the mortise is called the tongue, and the rest is called the shoulder. The mortise and tenon structure is widely used in construction and also in furniture. In the field of furniture, various types of cabinets belong to one category. Cabinets are appliances for storing documents, etc. They are square or rectangular, generally made of wood or iron, and can store items. The mortise-in-mortise structure is often used in cabinets, and the cabinets are quickly and firmly installed together through the mortise-in-mortise structure.

[0003] Currently, the existing detachable mortise and tenon structure mostly uses the mortise and tenon structure to splice cabinets to increase its scope of use, but it is not convenient to adjust the angle of the spliced ​​cabinets to adapt to various environments, and the practicality is low.
