The present invention relates to a buffer hinge. More particularly, the return spring is used to automatically open and close the door, and one end of the axis with a corresponding rotation is affixed with the buffer component with multiple convexes. The buffer component is positioned into the buffer container of the positioning component at one end of the positioning return spring. Moreover, the buffer container has multiple concaves for embedding the convexes of the buffer component. Therefore, when the angle for opening the door is larger, the return torque produced from the return spring has a greater increase. However, when the embedding number between the convexes and the concaves is relatively increased, the buffer resistance between the two is also larger. On the contrary, when the angle for closing the door is smaller, the return torque produced from the return spring has a smaller decrease. When the embedding number between the convexes and the concaves is relatively decreased, the buffer resistance between the two is also smaller. Therefore, the door does not act fast or slowly while opening and closing, and the impact between the door and the door socket will be minimized. |
