[0023] The technical solutions in the embodiments of the present utility model are clearly and completely described below in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present utility model, rather than all the embodiments.

[0024] See also Figure 1-4 The special hinge for ultra-thin toilet lids of the utility model can be used for the connection and installation of ultra-thin toilet lids.

[0025] In the present disclosure, Figure 1-3 As shown, the special hinge for the ultra-thin toilet cover includes: a lower connecting seat 100, including a seat body 101 and a mounting portion 103 arranged on the upper side of the seat body 101, a threaded hole 102 is arranged on the bottom side of the seat body 101, a mounting hole 104 penetrating the mounting portion 103 is arranged on the mounting portion 103, a limiting platform 105 is arranged at one end of the mounting hole 104, and a limiting groove 106 extending from an end away from the limiting platform 105 to an end close to the limiting platform 105 is arranged in the mounting hole 104; a damper 200, including a shaft body 201 and a rotating shaft 203 rotatable on the shaft body 201, a limiting protrusion 202 is arranged on one side of the shaft body 201, and the direction end of the rotating shaft 203 of the damper 200 is inserted into the mounting hole 104 from the end away from the limiting platform 105. , the end of the rotating shaft 203 protrudes out of the mounting hole 104, and the end of the shaft body 201 abuts against the limit platform 105, the end of the shaft body 201 away from the rotating shaft 203 protrudes toward the end of the mounting hole 104 away from the limit platform 105, and the limit protrusion 202 is embedded in the limit groove 106; the connecting ear 300 includes a connecting plate 301 and a connecting part 302, and the connecting part 302 is provided with a limited plug hole 305, and the limited plug hole 305 can be inserted into the rotating shaft 203 to rotate with the rotating shaft 203; the connecting ear 2 400 includes a connecting plate 2 401 and a connecting part 2 402, and the connecting part 2 402 is provided with a circular sleeve hole 406, and the sleeve hole 406 is inserted into the shaft body 201 so that the connecting ear 2 400 can rotate around the shaft body 201.

[0026] The lower connecting seat 100 is used to connect the toilet base, the connecting ear 1 300 is used to connect the toilet cover plate, and the connecting ear 2 400 is used to connect the toilet seat. The installation thickness is the distance between the upper surfaces of the connecting ear 1 300 and the connecting ear 2 400 when the connecting ear 1 300 and the connecting ear 2 400 are parallel to each other, which is usually smaller than the installation portion 103 and can be less than 10 mm.

[0027] from Figure 2 and Figure 3 It can be seen that the special hinge for the ultra-thin toilet lid is a detachable assembly structure. Usually, one toilet lid is provided with two special hinges for the ultra-thin toilet lid. After installation, the two connecting ears 2 are located inside the two connecting ears 1 300. Since the positions of the two connecting ears 1 300 are fixed by the toilet lid cover plate, and the positions of the connecting ears 2 are fixed by the two toilet rings, the special hinge for the ultra-thin toilet lid can be assembled reliably.

[0028] When the special hinge for the ultra-thin toilet seat is installed and used, the opening and closing of the toilet seat cover is controlled by the damper 200, which has a damping effect. The toilet seat can rotate freely between the toilet seat cover and the toilet base.

[0029] In the disclosed embodiment, the limiting platform 105 is an annular protruding structure protruding toward the axis direction of the mounting hole 104. Figure 1 As shown, to ensure the aesthetics and applicability of the design structure, the connecting plate 1 301 is tangent to the side of the connecting portion 1 302 away from the seat body 101 ; the connecting plate 2 401 is tangent to the side of the connecting portion 2 402 close to the seat body 101 .

[0030] In the disclosed embodiment, usually, the lower connecting seat 100, the connecting part 1 302, and the connecting part 2 402 are made of stainless steel to reduce the difficulty of manufacturing the accessories and reduce the manufacturing cost.

[0031] The connecting part 1 302 is provided with a non-circular groove 1 303, a support block 1 304 is embedded in the groove 1 303, and a limit socket 305 is provided on the support block 1 304. The socket can be used as follows Figure 2 As shown, the end of the rotating shaft 203 is a quadrilateral (square hole), and the limiting plug hole 305 is a quadrilateral adapted to the end of the rotating shaft 203. Further, an annular gasket 306 is provided at the end of the supporting block 1 304. When the supporting block 1 304 is embedded in the groove 1 303 and the limiting plug hole 305 is sleeved on the rotating shaft 203, the annular gasket 1 306 is supported between the connecting portion 1 302 and the mounting portion 103.

[0032] The second connecting portion 402 is provided with a second circular groove 403, in which a second supporting block 404 is embedded, and a sleeve hole 406 is provided on the second supporting block 404. Further, a second annular gasket 405 is provided at the end of the second supporting block 404, and when the second supporting block 404 is embedded in the second groove 403 and the sleeve hole 406 is sleeved on the shaft body 201, the second annular gasket 405 is supported between the second connecting portion 402 and the mounting portion 103.

[0033] Among them, in view of the high strength of nylon material and the fact that there is no abnormal sound when rubbing against stainless steel material, the support block 1 304 and the support block 2 404 are both made of nylon material.

[0034] To enhance the aesthetic, black nylon is used.

[0035] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto.
