Abstract

The application relates to the technical field of bathroom hardware installation, in particular to an installation and fixing structure, which comprises an installation main body, a fixing pin assembly and a fixing seat. The body is arranged at the inner side of the installation main body and can rotate relative to the installation main body, the periphery of the body is provided with a lug with a guide inclined plane, and the lug pushes the fixing pin to extend out radially by rotating the body. The fixing seat is buckled on the periphery of the installation main body, and a first annular groove is formed in the inner wall of the accommodating cavity of the fixing seat and used for accommodating the extending fixing pin to realize axial locking. In addition, the physical non-return is realized by embedding a stop block in the mounting groove of the body bulge and abutting against the side wall of the guide groove of the mounting main body. The application can eliminate part gaps by a rotary driving radial locking mode, improve connection stability and safety and effectively prevent loosening.
