Looking at the operation of the present invention as follows.

The oil damper according to the present invention is used by connecting and fixing the first connecting portion 120 and the second connecting portion 220 of the second rotating member 200 to the cover and the seat of the toilet bowl, respectively. .

7 and 8 are cross-sectional views showing an operating state of the present invention, Figure 7 is when the rotary object is lifted to the upper side in the state where the rotary oil damper is installed on the cover for the toilet is a rotating object, that is when to open the cover It shows the state that can be easily rotated without the resistance of the oil pressure, Figure 8 shows the state when the rotating object is rotated downward, showing a state in which the damping action by the oil pressure is performed, the first Since the operation of the rotating member 100 and the second rotating member 200 are made the same, a description will be made here by selecting the first rotating member 100.

As shown in FIG. 7, when the rotating object is rotated upward, the first rotating member 100 rotates with respect to the housing 1, and the oil filled in the housing 1 rotates of the first rotary compression 110. The pressurized piece 300 according to the pressurized by moving, so the pressurized oil is going to move to the other side through the pressurizing portion hole 320, and eventually the oil pushes the opening and closing member 400 to retreat while pressing the pressing portion hole ( The first rotating member 100 is rotated without deterioration by lowering the pressure by flowing out to the opposite side while continuously passing through the opening 320 and the opening / closing hole 430.

Here, the adjustment pin 420 is coupled to the pressing portion hole 320, the depth to which the control pin 420 is coupled with the retraction of the opening and closing member 400 is shallow, the pressing portion hole 320 It is made of a long hole there is no problem to pass a small amount of oil, but due to the retraction of the adjustment pin 420 can be passed through a larger amount of oil can be made easier rotation of the rotating member, and also the adjustment pin 420 ), The rapid movement of oil is controlled.

The rotation of the first rotating member 100 rotates as the pressing piece 300 contacts the stopper 7 of the housing 1.

On the contrary, when rotating the rotating object as shown in FIG. 8, the first rotating member 100 rotates in the opposite direction as in FIG. 7. Similarly, the first rotary compression 110 of the first rotating member 100 is rotated. The pressing piece 300 is moved by the rotation of the oil to press the oil, the oil is to act to move to the opposite side.

Thus, the opening and closing member 400 is pushed by the oil by the movement action of the oil rather close to the pressing piece 300 to block the pressing portion hole 320.

The pressurizing part hole 320 and the opening and closing part hole 430 forming the passage of oil are disposed to be offset from each other. When the opening and closing member 400 and the pressing piece 300 are in close contact with each other, the passage of the oil is blocked. Since only a small amount of oil is moved between the pressing piece 300 and the opening / closing member 400, the first rotating member 100 is slowly moved until the opening / closing member 400 contacts the stopper 110. It is rotated, and the cover of the toilet can be safely rotated downward without impact.
