Abstract

The invention discloses a rotary damper capable of adjusting torque force. A sealing cavity full of damping oil is defined by the surface of a containing section of a piston shaft and the inner wall of an outer shell, the upper portion of the containing section is provided with an oil leakage hole distributed in the radial direction, an oil channel is formed in the center of the top of the lower end of the containing section, and the oil channel is communicated with the center of the axis of the oil leakage hole; the containing section is provided with a radial through hole, an adjusting bolt is arranged in the through hole, a screw hole is axially formed in the top of the upper end of an exposed section, and an adjusting screw capable of adjusting oil leakage amount of the oil leakage hole is arranged in the screw hole; the containing section is sleeved with a piston sleeve capable of moving along the containing section vertically; when the two ends of the adjusting bolt move downward from the upper end to the lower end of an adjusting groove, no resistance is generated, and when the two ends of the adjusting bolt move upward from the lower end of the adjusting groove to the upper end of the adjusting groove, resistance is generated. According to the rotary damper, torque force can be adjusted and labor is saved in reset.

Description

technical field [0001] The invention relates to an adjustable torsional rotation damper, in particular to an adjustable torsional rotation damper used for hinge shafts when furniture and sanitary ware are opened and closed. Background technique [0002] At present, the parts of some devices rotate around the axis, such as the lids and toilet covers in furniture that need to be opened up and down. Very loud sound, the impact that causes is big; Another kind adopts spring to buffer, and easily can't be used because of spring corrosion again, and service life is short; Chinese patent 200920198690. The design has the disadvantages that the resistance generated when opening or resetting is the same, which makes the resetting process laborious and the resistance cannot be adjusted. Contents of the invention [0003] In order to overcome the disadvantages of the prior art that the resistance produced during the damping process is the same, resulting in laborious reset and the re...
