Abstract: A quick-release and quick-installation hinge assembly includes a hinge to which a toilet lid is rotatably connected, a key plate fixed on a toilet bowl, and a limiting member. The hinge is fixedly provided with a hinge base fitted with the key plate. The hinge base and the key plate are in insertion fit in a lateral direction. The limiting member is provided with an inserting portion. The key plate is provided with an inserting hole that is in insertion fit with the inserting portion for position limitation. The inserting portion is fitted with the inserting hole for position limitation to prevent the hinge base and the key plate from being separated from each other in the lateral direction. The inserting portion penetrates through the inserting hole. The quick-release and quick-installation hinge assembly realizes a stable convenient connection structure between the hinge base of the hinge and the key plate.

Abstract: The disclosure discloses a toilet seat assembly installation structure convenient for disassembly and assembly, which comprises fixing members fixedly installed on a toilet seat; a hinge base including hinge portions and installation portions, the hinge portions hinging with a cover plate, the installation portions engaging with the fixing members; and snap-in connection members configured to detachably and position-limitedly installed on the installation portions along a vertical direction so that the snap-in connection members are fixedly engaged with the fixing members, or to detachably and position-limitedly installed on the fixing members along the vertical direction so that the snap-in connection members are fixedly engaged with the installation portions. The toilet seat assembly installation structure is easy to operate, can be dissembled and assembled by inserting/removing the hinge base into/from the fixing members, and is stable and reliable.

Abstract: A quick assembly and disassembly mechanism with a button lock for a toilet cover has a straight tube pivot joint, two stands and two pivot shafts. Each pivot shaft is disposed with pin holes in the radial direction. A lock bar disposed between the pivot shafts can slide side to side. The straight tube is disposed with an operation mechanism to drive the lock bar to slide. A spring is disposed inside the straight tube to reposition the lock bar. The lock bar is disposed with a lock catch and a lock piece with lock hole. The lock catch has an elastic body and a lock piece to limit the sliding of the lock bar and a pivot shaft, which is plugged to the end of the lock bar in sliding way. The lock piece in the end of the lock bar is disposed with a lock hole.
