Segmented sLow descent hinge

Abstract

The invention discLoses a segmented sLow descent hinge which comprises a sheLL and a rotating piece which can rotate reLativeLy. A circuLar hoLe is formed in the sheLL, the rotating piece comprises aconnecting portion and a rotating shaft inserted into the sheLL, the sheLL and the rotating piece are matched to form a cLosed space, a bLocking portion is arranged inside the sheLL, an extending portion is arranged in the radiaL direction of the rotating shaft, a fan annuLar Limiting bLock is arranged on the extending portion, the outer peripheraL face of the fan annuLar Limiting bLock is attached to the sheLL, a groove is formed in the axiaL direction of the fan annuLar Limiting bLock, a first runner is arranged at one side of the groove, the groove and the extending portion are nested, a concave portion is arranged on the extending portion, a second runner is arranged on the concave portion, a third runner is arranged on the rotating shaft, the first runner, the second runner and the third runner are communicated, a spLice piece is arranged inside the concave portion, and underfiLLing Liquid is injected into the sheLL. The segmented sLow descent hinge can be rapidLy opened and rapidLy descend, and can achieve segmented sLow descent. The segmented sLow descent hinge can be rapidLy opened in one direction, and achieve sLow descent in the other direction.

Description

technical field [0001] The invention belongs to the technical field of hinges, in particular to a segmented slow-down hinge, which is especially suitable for being used as a toilet lid hinge, and also suitable for being used as a hinge for various box lids. Background technique [0002] The toilet lid needs to be able to turn up quickly when it is turned up, and when it is turned over, in order to prevent it from falling to make a loud noise or to prevent the toilet lid from breaking, a slow-down structure is generally provided in the hinge, and the existing toilet lid hinge Generally, the slow falling of the toilet lid is realized by setting mechanical structures such as torsion springs, but the existing hinge structure is relatively complicated, the processing cost is high, and it is difficult to be suitable for toilet lids of different weights. And the existing slow-falling hinges generally open quickly throughout the whole process when the toilet lid is opened, and slowl...

[0002] The toilet lid needs to be able to turn up quickly when it is turned up, and when it is turned over, in order to prevent it from falling to make a loud noise or to prevent the toilet lid from breaking, a slow-down structure is generally provided in the hinge, and the existing toilet lid hinge Generally, the slow fall of the toilet lid is realized by setting mechanical structures such as torsion springs, but the existing hinge structure is relatively complicated, and the processing cost is high, so it is difficult to apply to toilet lids of different weights.

And the existing slow-falling hinges generally open quickly throughout the whole process when the toilet lid is opened, and slowly drop throughout the whole process when the toilet lid is lowered. Generally speaking, it is not necessary to slowly lower the whole process when the toilet lid is closed, as long as it is about to touch the toilet. Just lower it, otherwise the closing time is too long. When using the toilet, you should normally flush the water after closing the toilet lid to prevent the bacteria in the toilet from entering the ambient air, and the toilet lid is installed with a slow-down hinge that closes for too long. will waste some time
