Abstract
The utility model relates to a lightly opened and heavily closed pivot device which comprises a pivot shaft, a fixed supporting frame, an electric element set and a fixed member, wherein a sleeve barrel is bent, folded and molded on one end of the fixed supporting frame, the lateral margin of the sleeve barrel is not connected with a fixed part, a notch is molded on the lateral margin of the sleeve barrel, the sleeve barrel is sheathed on the pivot shaft and the inner diameter of the sleeve barrel is smaller than the rod diameter of the pivot shaft. The electric element set is sheathed on the pivot shaft. The fixed member is sheathed and fixed on the tail end of the pivot shaft so as to clamp each element position; when the pivot shaft rotates, torque force can be generated because of the friction of the pivot shaft and the inner wall of the sleeve barrel; in this way, when the upper cover is relatively closed on a bottom seat, the notch of the fixed supporting frame can be closed, and thus, the sleeve barrel can generate resisting force; accordingly, the speed can be decelerated when the sleeve barrel is closed. When the upper cover is relatively opened on the bottom seat, the notch of the fixed supporting frame can be restored, the sleeve barrel can generate restoring force so as to accelerate opening speed, and thus, users need not exert additional force. The utility model utilizes the change of the self-torque force of the pivot device to achieve the aim controlling the speed when the upper cover is closed or opened.
