Hanging rack installation mechanism on wall surface

The invention discloses a hanging rack installation mechanism on a wall surface. The hanging rack installation mechanism comprises a hanging rack fixing seat, a wall surface fixing plate and an elastic buckle, wherein the wall surface fixing plate is movably connected with the hanging rack fixing seat, and the elastic buckle is matched on a wall surface fixing block; the wall surface fixing plate is fixed on the wall surface through a locking piece, a limiting buckle is arranged on the wall surface fixing plate, and the elastic buckle is matched in the position opposite to the limiting buckle; a sleeve seat which is buckled with the wall surface fixing plate is arranged on the back part of the hanging rack fixing seat. According to the hanging rack installation mechanism, a traditional installation mode that a hanging rack is directly locked on the hanging rack fixing seat is changed, the limiting buckle is arranged on the fixing plate and is matched with the elastic buckle, and the matching sleeve seat which is matched with the limiting buckle and the elastic buckle is arranged on the hanging rack fixing seat, so the functions of assembly and disassembly are realized; by using such a structure, the hanging rack fixing seat can be conveniently installed, removed and replaced; additionally, the hanging rack installation mechanism can be widely applied to support seats in different shapes and sizes, so as to be suitable for carrying out a standardization installation platform, and therefore, secondary damage to the wall surface due to replacement of the fixing plate can be avoided.
