Description
Technical field
The present invention relates to a kind of adjustable torsion rotary damper, particularly a kind of adjustable torsion rotary damper of hinge axis when opening and closing for furniture, sanitary equipment etc.
Background technology
At present, the parts of some devices rotate around axle, the lid opened up and down as needed in furniture, lavatory lid etc., main adopt two kinds of structures: a kind of is directly use pinned connection, and can send the very large sound opening, when putting down, the impact caused is large; Another kind adopts spring buffer, and easily again cannot use because of spring corrosion, application life is short; Devise a kind of snubber with blade for the problems referred to above Chinese patent 200920198690.0, but the resistance produced when this design exists unlatching or resets is identical, makes in reseting procedure, compare effort, the uncontrollable shortcoming of drag size.
Summary of the invention
For the resistance produced in damping process overcoming prior art existence is identical, cause during reset and compare effort and the uncontrollable shortcoming of drag size, the invention provides a kind of adjustable torsion rotary damper.
The technical solution used in the present invention is:
Adjustable torsion rotary damper, comprise the shell that one end closes and the lid be connected with outer casing screw, the axis of the piston is arranged in described shell along the longitudinal axis, described the axis of the piston comprises the section of including inserted in shell and the revealed section be connected with lid, the surface of the section of including of described the axis of the piston and the inwall of described shell enclose the annular seal space that is full of damping oil, it is characterized in that:
The described section of including top has the oil leaking hole of radial arrangement, and the lower end end top center of the described section of including is provided with an oily passage, and described oily passage is connected with the center of the axis of oil leaking hole;
The described section of including is arranged the through hole with radial arrangement, the axis of described through hole and the axis being parallel of described oil leaking hole; Be provided with adjusting bolt in described through hole, described through hole is stretched out at the two ends of described adjusting bolt;
The upper end top axle of described revealed section is to being provided with screw hole, and described screw hole communicates with described oil leaking hole, and is provided with the adjustment screw of an adjustable oil leaking hole leakage of oil amount in described screw hole;
The described section of including is arranged with a piston bush that can move up and down along the described section of including, described piston bush is symmetrically arranged with the regulating tank matched with the two ends of described adjusting bolt; When the two ends of described adjusting bolt are displaced downwardly to lower end from the upper end of regulating tank, non-resistance produces, and has resistance to produce when the two ends of described adjusting bolt move to lower end from the lower end of regulating tank;
The lower end of described piston bush has the circumferential recess be radially arranged in circumferentially, is provided with the U-shaped sealing ring of annular in described circumferential recess.
Further, the inside wall of described shell is provided with a circle internal thread, the lateral wall of described lid is provided with the external screw thread suitable with described internal thread.
Further, the top of the described section of including is provided with groove, is provided with the sealing ring coordinated with the inwall of described shell in described groove.
Further, sealing ring is provided with between the inwall of described the axis of the piston and described shell.
Further, the position that described adjustment screw top and described screw hole fit is provided with sealing ring.
The effect of the U-shaped sealing ring of annular of the present invention: in the axis of the piston rotary course, when piston bush moves from top to bottom, it is contraction state that the both sides of U-shaped sealing ring are subject to oily squeezing action, so leakage of oil amount is larger in this process, torsionless produces; When piston bush moves from the bottom up, the both sides of U-shaped sealing ring are subject to the oily open-shaped state of squeezing action and fit with the inwall of shell forming hermetically-sealed construction, so leakage of oil amount is smaller in this process, torsion is larger.Piston bush moves past in journey and make damper produce resistance, delay and fall successful.
The leakage of oil amount of the adjustable oil leaking hole of adjustment screw of the present invention, thus in damping process the size of adjustable torsion.
Technical conceive of the present invention is: be arranged on explanation on lavatory lid for the present invention.During installation, lid is fixed on toilet, the revealed section of the axis of the piston is connected with lavatory lid.
In opening process, the gravity of lavatory lid is all applied on damping oil, and when the axis of the piston rotates, the both sides of U-shaped sealing ring are opened and outer casing inner wall gluing, sealing, and the flow of damping oil is more and more less, and damping force is increasing, thus reaches cushioning effect.
In reseting procedure, when the axis of the piston rotates, the both sides of U-shaped sealing ring are shunk and leave space between outer casing inner walls, and oil flows through outer can also flowing through from gap from oily passage, thus accelerates the quick flowing of resistance oil, does not have damping force to produce.
Beneficial effect of the present invention is embodied in: delay to fall in process to delay and fall successful, and more laborsaving when renovating reset, and damping force is adjustable.
