The utility model relates to a bathroom wall hanging device which comprises a wall hanging body, two parallel straight plates are arranged at the lower end of the wall hanging body, sliding grooves extending longitudinally are formed in the opposite faces between the straight plates, the depth in the sliding grooves is gradually increased from bottom to top, and a liftable ball is installed between the sliding grooves. The surface of the sphere is an uneven
rough surface, and the
diameter of the sphere is larger than the distance between the two straight plates. An installation groove is formed in the outer side wall of a straight plate, the width of an outer side groove opening of the installation groove is smaller than the width of the inner side groove bottom, an
insertion opening of the installation groove is formed in the bottom end of the straight plate, an
insertion piece is inserted into the installation groove in a matched mode, and at least two round holes used for being matched with screws are formed in the
insertion piece. Compared with a traditional hook, the wall hanging device has the advantages that the fracture and deformation probability is greatly reduced, the wall hanging device does not need to depend on ultrahigh-
toughness materials, the use reliability is guaranteed, meanwhile, the material cost is reduced, the product
cost performance is improved, and market application and popularization are facilitated.
