The interaction between the toilet cover and the hinge

The hinge for the toilet cover is a connecting shaft and a hinge base. The connecting shaft is made of metal and is a solid structure fixed on the hinge base; the cost is high and the installation is inconvenient. The quick disassembly and assembly mechanism of the toilet cover includes a cover plate provided with an upper cover and a seat ring. The cover plate is connected to a hinge base fixedly arranged on the toilet through a transmission sleeve. The hinge base is provided with a connecting column, and the left and right sides of the connecting column A guide rib or a guide groove is provided, a limit chute is provided on the circumference of the transmission sleeve corresponding to the connecting column or the guide groove, and a gap is provided on the limit chute corresponding to the guide rib or the connecting column.

The cross section of the connecting column shaft is round or square, and the middle ring is provided with a guide groove; the transmission sleeve is fixed or integrally provided with a locking ring, and the locking ring is provided with a limit chute corresponding to the guide groove on the circumference, and the limit chute is correspondingly connected The surface of the column is provided with a void, and the transmission sleeve is also provided with a chute corresponding to the surface of the connecting column, and the connecting column vertically penetrates into the transmission sleeve through the void. This structure is easy to loosen during the rotation of the cover plate, and at the same time, it has many shortcomings and needs to be improved.

The hinge body of the new toilet cover plate is connected with the cover plate by a hinge, the hinge base fixedly connected to the toilet, and the connecting shaft connecting the hinge body and the hinge base. The upper end of the connecting shaft is fixedly connected with the hinge body, and the lower end is plugged with the hinge base; the hinge base The middle slide is provided with a locking block, and the locking block is buckled with the lower end of the connecting shaft. The connecting shaft is a hollow shaft, and a key core for separating the locking block from the connecting shaft is sleeved in the shaft hole. The new hinge connecting shaft is arranged on the hinge body, and the locking block buckled and matched with the connecting shaft is arranged on the hinge base, which is convenient for production and installation.

At the same time, a key core is slid up and down in the connecting shaft. The lower end of the key core extends to the locking block, and the upper end of the key core extends to the outside of the hinge. When the hinge body and the hinge base need to be separated, just press the key core and move toward Pull up the hinge body to realize the separation of the two. This structure is simple and reasonable, easy to disassemble and assemble, and has a long service life.
