[specific embodiment]
Below in conjunction with accompanying drawing and embodiment of the present utility model, be described in further detail:
Referring to Fig. 1-5, the utility model is a kind of buffer that can make lavatory lid fast-descending, include stack shell 1 and axle core 2, described axle core 2 one end are contained in the inner chamber of stack shell 1, axle core 2 other ends stretch out outside stack shell 1, on axle core 2, be provided with the fin 3 tangent with stack shell 1 inwall, described axle core 2, between fin 3 and stack shell 1, surround for filling the oil pocket of damping oil, the arc oil unloading trough 5 that is provided with arc oil sealing surface 21 and communicates with oil pocket on axle core 2 outer walls between adjacent described fin 3, the corresponding central angle of described arc oil unloading trough 5 is greater than the corresponding central angle of arc oil sealing surface 21, at described stack shell 1 inwall, be provided with the oil sealing lug 4 that protrudes inwall, in described oil sealing lug 4 ends, be provided with the arc oil sealing portion 41 coordinating with arc oil sealing surface 21, when described axle core 2 turns to arc oil sealing surface 21 and contacts with arc oil sealing portion 41, between arc oil sealing surface 21 and arc oil sealing portion 41, form oil sealing surface, when described axle core 2 turns to arc oil unloading trough 5 and overlaps with arc oil sealing portion 41, between arc oil unloading trough 5 and arc oil sealing portion 41, form the passage for damping oil circulation.
The corresponding central angle of described arc oil unloading trough 5 is 3-4 times of arc oil sealing surface 21 corresponding central angles.Referring to Fig. 3, this product 100 is arranged on existing seat lavatory, and can make water closet cover-plate is since 95 ° of fast-descendings to just starting descending at slow speed with 15 °-20 ° of horizontal plane angles, has further shortened cover plate fall time.
The end that is positioned at axle core 2 in stack shell 1 is provided with the adjusting device 6 for the interval area of damping adjusting oil flow, adjusting device 6 comprises the adjusting nut 61 that is arranged on stack shell 1 opening part, on described stack shell 1 inwall, be provided with the internal thread coordinating with adjusting nut 61, between adjusting nut 61 and axle core 2 ends, being provided with can be along with adjusting nut 61 be along stack shell 1 inwall regulating block 62 in axial sliding, between regulating block 62 and axle core 2 ends, form gap, regulating block 62 outer walls and stack shell 1 inwall seal by sealing ring 7.In described axle core 2 ends, be provided with center plug 22, on described regulating block 62, be provided with the central recess 621 inserting for center plug 22.
On described axle core 2 other end outer walls, be provided with annular breach 23, on the stack shell 1 inwall position corresponding with annular breach 23, be provided with internal thread, in annular breach 23, be provided with the annular gland 8 being threaded with stack shell 1, the ring-shaped step clamping at the bottom of described annular gland 8 and annular breach 23 places is provided with the centre bore passing for axle core 2 on annular gland 8.
On described annular gland 8, be provided with the annular edge 81 with the 2 end clampings of axle core.
Between the bottom of annular gland 8 and the ring-shaped step at annular breach 23 places, be provided with annular gasket 9.
This uses novel operation principle as follows: when the cover plate in seat lavatory or seat ring are started by user, because blade 10 and the flow-guiding structure on stack shell and axle core cannot form oil sealing surface, the moment of torsion that damping oil forms on axle core is very little, and like this, cover plate or seat ring can be opened rapidly.
When the cover plate in seat lavatory or seat ring are put down by user, axle core 2 is driven and rotates counterclockwise, due to damping oil pressurized, the counter-pressure producing is adjacent to blade 10 and axle core, but, between arc oil unloading trough 5 and arc oil sealing portion 41, form the passage for damping oil circulation, make the axle core 2 can quick rotation under the effect of cover plate or seat ring gravity, when axle core forwards to fast, to make cover plate or seat ring and horizontal plane angle be 15 °-20 °, between arc oil sealing surface 21 and arc oil sealing portion 41, form oil sealing surface, damping oil under pressure, from each gap by pressurized chamber, flow to not pressurized chamber, now, because the gap gross area is little, on mandrel, produce large changing and rush moment of torsion, like this, cover plate or seat ring can fall lentamente.
When needing the cover plate in adjustment seat lavatory or seat ring falling speed, by the mobile interval area of rotation adjusting nut damping oil, be convenient to like this flow velocity of damping adjusting oil as required, realize cover plate or the seat ring falling speed in adjusting seat lavatory.
Above-described embodiment is only preferred embodiment of the present utility model; can not limit protection domain of the present utility model with this, the variation of any unsubstantiality that those skilled in the art does on basis of the present utility model and replacement all belong to protection domain of the present utility model.
