Description
Technical field
The present invention relates to a kind of adjustable torsion rotary damper, particularly a kind of adjustable torsion rotary damper of the hinge axis while opening and closing for furniture, sanitary equipment etc.
Background technology
At present, the parts of some devices rotate around axle, and the lid of opening up and down as needed in furniture, lavatory lid etc., mainly adopt two kinds of structures: a kind of is directly with bearing pin, to connect, and can send the very large sound when opening, putting down, and the impact causing is large; Another kind is to adopt spring buffer, easily because of spring corrosion, cannot use again, and application life is short; For the problems referred to above Chinese patent 200920198690.0, designed a kind of snubber with blade, but this resistance that designs generation when having unlatching or resetting is identical, makes relatively to require great effort, the uncontrollable shortcoming of drag size in reseting procedure.
Summary of the invention
Identical for overcome the resistance producing that prior art exists in damping process, cause while resetting and relatively require great 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, the shell and the lid being connected with outer casing screw that comprise one end closure, 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 and the revealed section being connected with lid of inserting in shell, the inwall of the surface of the section of including of described the axis of the piston and described shell encloses an 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 upper through hole with radial arrangement that arranges of the described section of including, the axis of described through hole is parallel with the axis of described oil leaking hole; In described through hole, be provided with adjusting bolt, 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 in described screw hole, is provided with the adjustment screw of an adjustable oil leaking hole leakage of oil amount;
In the described section of including, be arranged with a piston bush that can move up and down along the described section of including, on described piston bush, be symmetrically arranged with the regulating tank matching 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, when the two ends of described adjusting bolt have resistance to produce when the lower end of regulating tank moves to lower end;
The lower end of described piston bush has the circumferential recess being radially arranged on circumference, is provided with the U-shaped sealing ring of annular in described circumferential recess.
Further, on the inside wall of described shell, be provided with a circle internal thread, on the lateral wall of described lid, be 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 coordinating with the inwall of described shell in described groove.
Further, between described the axis of the piston and the inwall of described shell, be provided with sealing ring.
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, the both sides of U-shaped sealing ring are subject to oily squeezing action and are contraction state, 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 open-shaped state of oily squeezing action and form hermetically-sealed construction with the inwall laminating of shell, so leakage of oil amount is smaller in this process, torsion is larger.On piston bush, move past in journey and make damper produce resistance, the slow successful that falls.
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: it is example explanation that the present invention of take is arranged on lavatory lid.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, open and outer casing inner wall gluing, sealing the both sides of U-shaped sealing ring, and the flow of damping oil is more and more less, and damping force is increasing, thereby reaches cushioning effect.
In reseting procedure, when the axis of the piston rotates, between the contraction of the both sides of U-shaped sealing ring and outer casing inner wall, leave space, oil can also flow through from gap from oily passage flows through, thereby has accelerated the rapid flow of resistance oil, does not have damping force to produce.
Beneficial effect of the present invention is embodied in: slow falling in process delayed and fallen successful, and more laborsaving when renovating reset, and damping force is adjustable.
