Description

Technical Field

[0001] The utility model relates to the technical field of furniture, in particular to a mortise and tenon injection molding part suitable for assembling and connecting various furniture. Background Art

[0002] Existing furniture can be divided into two types: detachable and non-detachable. The detachable structure is for easy transportation and installation at home. Therefore, when assembling, adjacent parts need to be fixed by connectors. The connectors on the market have the following problems: 1. It is inconvenient to install because there are many screws and it is necessary to distinguish between left and right; 2. If hanging hardware is used, it is easy to make abnormal noises and shake, and there is a risk of falling off.

[0003] The existing Chinese patent with publication number CN217603096U discloses a connector and furniture using the same. The existing furniture connectors are complicated to assemble and have poor structural strength. The utility model includes a main part and a sub-part that are separated and detachable, the main part is provided with a main connection part with a limit groove, and the sub-part is provided with a sub-connection part with a limit block. When the main connection part and the sub-connection part are vertically stacked, the limit block is vertically inserted into the limit groove to limit the main part and the sub-part horizontally. The patent shows that a vertically through-hole 13 is provided on the main connection part 10, and a screw hole 14 open downward is provided on the sub-connection part 11. 13 is a through hole, and 14 is a screw hole, but the upper part 5 of the locking part and the butterfly-type screw handle are all full-threaded structures, which will result in: when the locking part or the butterfly-type screw handle is installed on the main connection part and the sub-connection part, the part of the through hole 13 is not tightly engaged by the thread. The screw hole 14 is open downward and closed at the top, which places strict requirements on the length of the screw on the locking piece or the upper part of the butterfly screw. Once the screw is too long due to tolerance, there is a risk of breaking the closed structure. There is also a situation where the bottom of the main connection part 10 cannot fit tightly with the locking piece after assembly. The above two problems may lead to poor strength of the furniture.

[0004] Therefore, the inventor believes that it is necessary to provide a mortise and tenon injection molded part suitable for the assembly and connection of various furniture, so as to improve the overall force strength of the assembled furniture through the plug-in cooperation of the mother part, the child part and the fastener. This can not only solve the problem of inconvenient installation of connecting parts on the market, but also can be assembled freely without distinguishing the installation direction.
