Described slot 4 is the dovetail groove that end osculum is large.
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.
At stack shell 1 other end inwall, be provided with outer ring card platform 11, be provided with the interior annular snap platform 21 being connected on outer ring card platform 11 on axle core 2, outer ring card platform 11 seals by sealing ring 7 with axle core 2.
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.
Compared with prior art, the beneficial effects of the utility model are:
1, on the other axle outer core of described fin, have slot, in slot, be fitted with outer end its swing and seal or open the movable mounting of unloading port relatively, like this, because movable mounting is inserted into axle in-core, movable mounting is just not easy deviate from or misplace between stack shell and axle core, good product quality, stable work in work.
2, movable mounting is arranged on by fin, and movable mounting is driven and to be rotated by axle core, does not have mutual stressed between movable mounting and fin, therefore, movable mounting and fin are durable, all fracture, good product qualities of being not easy in the process of long-time use.
3, movable mounting is a sheet material, and floor and emptying breach need not be set, simple in structure, easy to process, durable.

[specific embodiment]
Below in conjunction with accompanying drawing and embodiment of the present utility model, be described in further detail:
Referring to Fig. 1-6, the utility model is a kind of rotary buffer easy to assembly, 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, on described fin 3, be provided with unloading port 31, on other axle core 2 outer walls of described fin 3, have slot 4, in slot 4, be fitted with outer end its swing and seal or open the movable mounting 5 of unloading port 31 relatively, when described axle core 2 clockwise rotates, it is movable that mounting 5 is separated with fin 3 makes unloading port 31 open-minded, when described axle core 2 rotates counterclockwise, movable mounting 5 withstands on fin 3 Shang Shi unloading ports 31 and is shut.
Described slot 4 is the dovetail groove that end osculum is large.
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.
At stack shell 1 other end inwall, be provided with outer ring card platform 11, be provided with the interior annular snap platform 21 being connected on outer ring card platform 11 on axle core 2, outer ring card platform 11 seals by sealing ring 7 with axle core 2.
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.
This uses novel operation principle as follows: when the cover plate in seat lavatory or seat ring are started by user, referring to Fig. 5-6, axle core 2 is driven and clockwise rotates, and due to damping oil pressurized, the counter-pressure of generation rotates counterclockwise movable mounting 5, movable mounting 5 is separated with fin 3, unloading port 31 is open-minded, and the damping oil in pressurized chamber flows in pressurized chambeies by unloading port 31, thereby makes the moment of torsion that forms on axle core very little, 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, referring to Fig. 3-4, axle core 2 is driven and rotates counterclockwise, due to damping oil pressurized, the counter-pressure of generation makes movable mounting 5 be adjacent to fin 3, and movable mounting 5 is shut unloading port 31, produce oil sealing plane, damping oil under pressure, flows to not pressurized chamber from each gap by 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.
