Definitions

  • the present invention relates to a wall-mounted toilet, and more particularly to a wall-mounted toilet fixing device.
  • a wall-mounted toilet C is a toilet that is directly mounted to a mounting base W (the wall or water tank fixing bracket). The bottom of the toilet does not come into contact with the floor, thus saving the bathroom space.
  • the toilet is fixed to the mounting base through a fixing device.
  • a conventional wall-mounted toilet fixing device comprises a body 1', a screw sleeve 2' and a screw 3' fitted in the body 1'.
  • the screw sleeve 2' is provided with a concave surface 21'.
