INSTALLATION STRUCTURE OF COVER PLATE OF SEAT TOILET

摘要

An installation structure of a cover plate of a seat toilet, comprising a panel (1), a base plate (2) and a fast-installation mechanism and characterized in that the fast-installation mechanism comprises at least one panel hinge (10) fixed on the panel and on the rear portion of the base plate, a base plate hinge (8) and a rotating connection piece connected to the panel and the base plate in a rotating and hinged mode. The rotating connection piece comprises a hinge seat (6) and a damper (9), and a decoration cover (3), a positioning switch (4) and a threaded clamping ring (5) are installed at the upper end of the hinge seat (6) in sequence. An elastic threaded arm (5.2) used for being connected to the upper portion of a fixed threaded rod (7) in a threaded mode is arranged inside the threaded clamping ring (5), and fixation and looseness of the fast-installation mechanism and the fixed threaded rod (7) are achieved by rotating the positioning switch (4) and transmitting the threaded clamping ring (5). Threads on the lower portion of the fixed threaded rod (7) penetrate through ceramic (14) and are provided with a nut component composed of a spacer (11), a nut inner sleeve (12) and a nut outer sleeve (13). A section of the nut outer sleeve (13) is of a concave shape, and two ends of the nut outer sleeve are communicated with each other. The nut inner sleeve (12) is placed inside the nut outer sleeve (13) and is limited at a free end of the nut outer sleeve (13) in a matched mode by the spacer (11). The installation structure of the cover plate of the seat toilet is simple in structure, reliable in function and convenient to operate.
