[specific embodiment]
Be described in further detail below in conjunction with accompanying drawing and embodiment of the present utility model:
Referring to Fig. 1-6, the utility model is a kind of rotary buffer, include stack shell 1 and axle core 2, on stack shell 1 inwall, be provided with the shim 3 of projection, 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, 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, in that damping oil all is not equipped with in pressurized chamber 20 and pressurized chamber 30, 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, is provided with a plurality of slide openings 511 that insert successively for fixture blocks 61 on arc mainboard 51, slide opening 511 make fixture block 61 in slide opening 511, to slide greater than fixture block 61, axle core 2 is when clockwise rotating, fin 4 separate with oil sealing floor 52 make blade 5 with and fin 4 between formation Oil Guide passage 7; Axle core 2 is when rotating counterclockwise, and oil sealing floor 52 withstands on the fin 4 of a core 2 the Oil Guide passage is shut, and is not communicated with between pressurized chamber 20 and the pressurized chamber 30.
Shim 3 is two, and they are distributed on stack shell 1 inwall symmetrically, and 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 fin 4, blade 5 and shim 3 are divided into 2 not pressurized chamber 20 and 2 pressurized chambeies 30 again 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 channel sized.
The novel operation principle of this use is as follows: when the cover plate in seat lavatory or seat ring are started by the user, 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 to make between blade 5 and the fin 4 and to constitute Oil Guide passage 7, at this moment, pressurized chamber 20 interior damping oils can not flow in the pressurized chambeies 30 by Oil Guide passage 7; Perhaps by discharge orifice 9, oil storage pipeline 10 are flowed in the pressurized chamber 30.When the cover plate in seat lavatory or seat ring are put down by the user, axle core 2 is driven and is rotated counterclockwise, blade 5 is subjected to 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, damping oil in the pressurized chamber 30 can't flow into not in the pressurized chamber 20 by Oil Guide passage 7, and can only pass through discharge orifice 9, oil storage pipeline 10 flows 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 cover plate that needs the adjustment seat lavatory or seat ring falling speed, can adjust the length of inserting column in the oil storage pipeline of regulating part by the rotation adjustment screw, regulate oil storage oil in storage volume, be convenient to regulate as required the flow velocity of damping oil like this, realize adjusting the cover plate or the seat ring falling speed in seat lavatory.
