  • the plug pin and the blind hole are mounted by interference fit, resulting in inconvenient installation or disassembly of the toilet seat on the ceramic toilet bowl.
  • a fixed shaft used for pivoting a toilet seat is axially or radially mounted with a locking buckle to lock and unlock an plug pin, so that the toilet seat can be assembled and disassembled easily.
  • One end of the fixed shaft, not having a buffer is axially provided with the locking buckle.
  • the buffer and the locking buckle are installed at both ends of the fixed shaft, respectively.
  • the locking buckle and the buffer are not at the same side of the fixed shaft on the plug pin.
  • the present disclosure provides a rotary quick-dismounting hinge and a toilet seat having the hinge.
  • the hinge is assembled and disassembled by turning the toilet seat to a predetermined angle, so that the toilet seat can be assembled to and disassembled from a ceramic toilet bowl easily and conveniently.
  • An end face of a support completely bears the pressure of the toilet seat.
  • the torsion generated by turning the toilet seat down slowly is jointly supported by the support and an plug pin on the support.
  • the longitudinal connection strength between a shaft and the support is greater.
  • the assembly of the present disclosure and an upper cover shaft sleeve can be more flexible and convenient.
  • a rotary quick-dismounting hinge is provided.
  • the rotary quick-dismounting hinge comprises a support and a shaft.
