Description

TECHNICAL FIELD

[0001] The present disclosure relates to the technical field of toilets, in particular to a hinged structure structure for a toilet cover plate.

[0002] A hinged structure for a toilet cover plate is known from document CN 107 348 892 A.

BACKGROUND

[0003] At present, the hinge shaft assembly used for the hinge between the cover plate and the toilet on the market includes an oil core which is inserted and matched with the seat hinge and the seat hinge. In the prior art, the oil core and the seat hinge are separated. For example, the Chinese patent discloses (Publication No.: CN201767898U) a hinge structure of the toilet cover plate, and the specification specifically discloses the following contents: Referring FIG. 1-FIG. 9, the hinge structure of the toilet cover plate includes a cover plate connected with the toilet through a hinge. The hinge includes a hinge body (equivalent to a seat hinge) and a mounting seat respectively connected with the cover plate and the toilet. The top surface of the mounting seat is provided with a connection column, which is inserted and connected with the hinge body. The cover plate includes a bottom ring and a face cover. The left and right sides of the rear edge of the bottom ring are connected with hinges through springs, and the rear end of the hinge is provided with a damper (equivalent to oil core) connection groove, which is connected with the face cover through the damper. This kind of split structure mainly has the following defects:

1. The seat hinge and oil core are separated, so that their connection will lead to large coaxiality error of hinge shaft assembly;

2. The hinge shaft assembly also includes a return spring, which not only increases the production cost of the product, but also increases the assembly difficulty of the hinge shaft assembly.

[0004] In addition, when the traditional damper is installed to the seat ring, it also needs to add some parts to cooperate with them, such as gland, nut, anti-skid washer, decorative ring, snap ring and other parts, but this part will lengthen the overall appearance size of the hinge shaft, resulting in poor swing stability of the cover plate.
