[specific embodiment]

Be described in further detail below in conjunction with accompanying drawing and embodiment of the present invention:

Referring to Fig. 1-6, the present invention is a kind of rotary buffer, includes stack shell 1 and axle core 2; On stack shell 1 inwall, be provided with protruding shim 3, axle core 2 one ends are contained in stack shell 1 inner chamber and afterwards and between the stack shell 1 form annular seal space, and axle core 2 other ends stretch out outside the stack shell 1; On axle core 2, also be provided with fin 4; Between fin 4 and stack shell 1, be provided with blade 5, fin 4, blade 5 and shim 3 are divided into not pressurized chamber 20 and pressurized chamber 30 with stack shell 1 inner chamber, and 20 all are not equipped with damping oil with pressurized chamber 30 in pressurized chamber; On fin 4, be provided with a plurality of emptying breach 6; Between emptying breach 6, be provided with fixture block 61, blade 5 includes arc mainboard 51 and is arranged on arc mainboard 51 oil sealing floor 52 on one side, on arc mainboard 51, is provided with the slide opening 511 that a plurality of confession fixture blocks 61 insert successively; Slide opening 511 makes fixture block in slide opening 511, to slide greater than fixture block 61; Be provided with the envelope notch part that covers on corresponding emptying breach 6 between two adjacent slide openings 511 on the arc mainboard 51, when said axle core 2 clockwise rotated, fin 4 separates with oil sealing floor 52 made formation Oil Guide passage 7 between blade 5 and the fin 4; When said axle core 2 rotated counterclockwise, oil sealing floor 52 withstood on the fin 4 of a core 2 the Oil Guide passage is shut.

Shim 3 is two, and they are distributed on stack shell 1 inwall symmetrically; Two shims 3 are divided into two chambeies with stack shell 1 inner chamber; Fin 4 also is two, and they also are distributed on a core 2 outer walls symmetrically, and blade 5 also is two; Arc mainboard 51 outer walls and stack shell 1 inwall of blade 5 are tangent, and said fin 4, blade 5 and shim 3 are divided into 2 not pressurized chamber and 2 pressurized chambeies with stack shell 1 inner chamber.

Be provided with dividing plate 8 at stack shell 1 middle part; The both sides that on dividing plate 8, are positioned at shim 3 be respectively equipped be communicated with not pressurized chamber, pressurized chamber to discharge orifice 9; Be provided with and the oil storage pipeline 10 that discharge orifice 9 is communicated with in stack shell 1 other end inside, in oil storage pipeline 10, be inserted with the regulating part 11 of removable adjusting oil storage pipeline 10 oil storage volumes.

Oil storage pipeline 10 is symmetricly set in the stack shell 1; Said regulating part 11 includes base plate 110; Be provided with two at base plate 110 two ends and can corresponding be inserted into two inserting columns 111 in the oil storage pipeline 10; Be provided with jack 112 at base plate 110 middle parts, the adjustment screw 13 of passing jack 112 and being threaded with dividing plate 8 be housed in base plate 110 ends.On inserting column 111, be provided with cannelure 113, between this cannelure 113 and oil storage pipeline 10 inwalls sealing ring 115 be housed.

The novel operation principle of this use is following: when the cover plate in seat lavatory or the seat ring person of being used start; Axle core 2 is driven to clockwise rotate; The fixture block 61 of fin 4 carries out axial rotation in emptying breach 6; Fin 4 separates with oil sealing floor 52 makes between blade 5 and the fin 4 and to constitute Oil Guide passage 7 that at this moment, the damping oils in the pressurized chamber 20 can flow in the pressurized chambeies 30 through Oil Guide passage 7; Perhaps through discharge orifice 9, oil storage pipeline 10 are flowed in the pressurized chamber 30.When the cover plate in seat lavatory or the seat ring person of being used put down, axle core 2 was driven and is rotated counterclockwise, and blade 5 receives the pressure of damping oil; Thereby oil sealing floor 52 withstands on the fin 4 of a core 2 the Oil Guide passage is shut; Be not communicated with between pressurized chamber 20 and the pressurized chamber 30, the damping oil in the pressurized chamber 30 can't flow into not in the pressurized chamber 20 through Oil Guide passage 7, and can only be through discharge orifice 9, oil storage pipeline 10 being flowed into not in the pressurized chamber 20; Because discharge orifice 9 relative Oil Guide passages 7 are much smaller; Therefore, damping oil flow into not from flowing into pressurized chamber 30 that the speed in pressurized chamber 20 also will compare slowly, can make that like this cover plate in a lavatory or seat ring fall lentamente.

When needs are regulated cover plate or the seat ring falling speed in seat lavatory; Can adjust the length of inserting column in the oil storage pipeline of regulating part through the rotation adjusting screw; Regulate oil storage oil in storage volume; Be convenient to regulate as required the flow velocity of damping oil like this, realize the cover plate or the seat ring falling speed in adjustment seat lavatory.
