After oil sealing rib 102 in the fuel reserve tank ladle body and rotating shaft 50, slide block 40 cooperate, damping oil is divided into a1, a2, four zones of b1, b2.
When lavatory flap plate begins to fall, the inner case of buffer device as shown in figure 10, rotating shaft 50 is moved counterclockwise, this moment, slide block 40 was the spacing rib of the slide block on the clamping shaft 50 under the pressure of the damping oil shown in the arrow 90, formed sealing.Simultaneously, again because the effect of the pressure regulation groove 403 of slide block 40 1 sides, the damping oil 90 of pressurized can be pushed slide block 40 toward the outside direction of axis, makes slide block 40 be adjacent to the inwall of fuel reserve tank 10, and 90 of damping oils can not flow through from slide block 40.At this moment, b1 district and b2 district are confined area, and a1 district and a2 district are stress-free oil back region.The boss end of locking nut 20 and rotating shaft 50 end faces leave gap (seeing damping oil shown in Figure 9 90 present positions), extruded damping oil 90 is through the groove 101 in the containing cavity of fuel reserve tank 10, flow in the gap of locking nut 20 and rotating shaft 50, flow to a1, a2 zone through the gap again.Therefore, as long as control oil return speed, promptly can be controlled in the rotating speed (being the time that lavatory flap plate falls slowly) of certain moment of torsion lower rotary shaft 50 by the size of regulating the oil return gap.The gap is more little, and then the damping oil of process is just few more in the unit interval, and the time that falls slowly of lavatory flap plate is just long more.The gap is big more, and then the damping oil of process is just many more in the unit interval, and under the situation that the damping oil capacity equates, the time that falls slowly of lavatory flap plate is just short more.
In the flap plate dropping process of lavatory, the effect that oil groove 501 plays the balance fall time is crossed in the gradual change in the rotating shaft 50.Being set as follows of oil groove 501 crossed in this gradual change: the cover plate closing process is to make the process of rotation around rotating shaft 50, spend to the process of 0 degree from 90, the moment of torsion that cover plate countershaft 50 applies is increasing, gradual change in the rotating shaft 50 of the utility model design is crossed oil groove 501 and is narrowed down gradually in this process, the flow of unit interval internal damping oil is gradually few, the resistance that rotating shaft 50 is subjected to damping oil is gradually big, becomes big difference thereby offset cover plate moment relatively, therefore makes that the speed of cover plate dropping process is more even.
Relative, the inner case of buffer device as shown in figure 11, slide block 40 meetings damped oily 90 extruding along clockwise direction, this moment, slide block 40 can form a unobstructed passage with rotating shaft 50 places, damping oil 90 can very fast refluxing, so can produce moment of torsion hardly, the feasible lavatory needed power of flap plate of raising is littler.
The buffer device that the utility model provides, four grooves and a pair of oil sealing rib are set in the containing cavity of fuel reserve tank, it is with after slide block and rotating shaft match, form four unique drainback passages, make product when producing and install, need only guarantee the axiality of fuel reserve tank and rotating shaft, just play sealing and the effect of regulating as for locking nut, it is coaxial to make excessive demands fuel reserve tank, rotating shaft and locking nut three, and this design has reduced the required precision of Mould Machining and production process.And the utility model also designs on slide block the pressure regulation groove, makes slide block be adjacent to fuel reserve tank in rotation process, with the enhanced leaktightness effect.In addition, also be provided with in the rotating shaft and monosymmetricly cross oil groove by wide to narrow gradual change, the speed that lavatory flap plate is fallen in the process slowly is more even.The buffer device that the utility model provides may be used in the lavatory, can realize the effect that falls slowly of lavatory flap plate, has simple in structure, working stability, the time advantage easy to adjust that falls slowly.
