The invention provides a rotary buffer which comprises a shaft sleeve, a rotary shaft, an oil passing space, blades and an adjusting piece; the blades are rotatably matched with the tail end of the rotary shaft, the side edges of the blades are provided with fins, and the fins and a rotor wing plate are matched and switched between a closed state and an open state so that damping oil can flow. Limiting structures are arranged between the blades and the rotating shaft. The fins and the rotor wing plates are matched to be switched between the closed state and the open state, so that damping oilis driven to flow in a damping state or a non-damping state, the rotor wing plates and the fins are of an up-down structure, the overall thickness of the rotor wing plates is reduced, and the rotatable angle of the rotating shaft is increased; therefore, a larger opening angle of a closestool cover plate is realized. The adjusting piece can be matched with the blade structure to adjust the slow falling time of a buffer. Meanwhile, a damping oil circulation channel formed by the staggered mode of the fins and the rotor wing plates is larger, and rapid backflow of an oil way can be achieved.
Description
technical field [0001] The invention relates to the technical field of a hydraulic damper for a toilet cover, in particular to a rotary buffer. Background technique [0002] The toilet generally includes a ceramic base, a hinge device fixed on the ceramic base, and a cover plate hinged on the hinge device. The cover needs to be opened during the use of the toilet, and the cover is often closed when the toilet is not in use. At present, the toilet is equipped with a damper on the hinge device, and the cover plate is connected to the damper; when the cover plate falls with the hinge device as the center of rotation, the damper will allow the cover plate to decline slowly, which can prevent this. The dry smash falls on the ceramic seat. [0003] In the prior art, the damper applied to the cover plate is composed of a shaft center, a shaft sleeve, and a damping member located between the shaft center and the shaft sleeve. The damping oil is located in the cavity formed by the ...
