The low pressure oil pocket 12 of chamber 11 or two is connected, corresponding, the cutoff hole 23 and the passage 22 that dams be provided with two and respectively with
The two low pressure oil pocket 12 or two high-voltage oil cavities 11 are connected.Specifically, the front end of rotating shaft 20 open up vertically four it is in the same size
And the bar v notch v described above of circumferentially spaced setting, four bar v notch vs and two high-voltage oil cavities 11 and two low pressure oils
The correspondence of chamber 12, and be correspondingly connected with high-voltage oil cavity 11 and low pressure oil pocket 12.
As shown in fig. 7, the damper that Fig. 7 depicts the present embodiment has the course of work schematic diagram of damping state, and now, resistance
Buddhist nun's oil pressure promotes plectrum 50 to swing the excessively oily passage close between rotating shaft 20 and plectrum 50, and damping oil is only capable of from by adjusting
The regulation passage of oil excessively that chamber 21, the passage 22 that dams, cutoff hole 23, flow channels 24 and flowing hole 25 are formed or other fixed oil
Passage flow, thus realize it is slowly excessively oily, it is slow excessively oil when produce damping buffering effect cause that lavatory lid can be covered slowly.
As shown in figure 8, Fig. 8 depicts the course of work schematic diagram of the damper undamped state of the present embodiment, damping oil
Pressure promotes plectrum 50 to swing the excessively oily passage open between rotating shaft 20 and plectrum 50, real so as to improve oily ability
Now quick excessively oily, lavatory lid can be started easily during quick oil excessively.
As shown in figure 9, damper is in complete current floe condition, it is complete that the regulating part 40 moves axially to the rear end of smooth section 42
The totally-enclosed cutoff hole 23 corresponding dam passage 22 and the corresponding flow channels 24 of flowing hole 25 so that
The regulation passage of oil excessively of governor motion of the present utility model is closed, it is impossible to excessively oily, and damping oil is only capable of by above-mentioned plectrum 50
The excessively oily passage of control carried out oil, and regulating part 40 only need to backward be adjusted to the rear end of smooth section 42 and fully pass over cutoff hole 23 i.e.
The regulation passage of oil excessively for being capable of achieving governor motion is completely enclosed, and effect of damming completely is good；
As shown in Figure 10, damper makes the regulating part 40 moved axially forward to smooth section in part current floe condition
42 open cutoff hole 23 corresponding dam passage 22 and the corresponding flow channels 24 of flowing hole 25, now, regulation
Chamber 21, the passage 22 that dams, cutoff hole 23, flow channels 24, flowing hole 25 are interconnected so that governor motion of the present utility model
Excessively oil regulation passage be in half-open position, can according to cross oil mass demand adjust cutoff hole 23 aperture size, so as to realize
Damping regulation.
Make the governing response of damping mechanism quick, sensitive using said structure, and dam control more precisely, act more flat
Surely, damping is more preferable, it is adaptable to which the ramp down time would of closet cover plate is precisely controlled, and simple structure is easy to operate, additionally, by
The correspondence position that is located at housing 10 inside can be provided only in rotating shaft 20 in regulation chamber 21, and regulating part 40 is stretched into from the front end of rotating shaft 20
Regulation chamber 21 is adjusted, and can so avoid regulation chamber 21 through the front and back end of rotating shaft 20 again using regulating part 40 from the rear end of rotating shaft 20
Stretching into the scheme that is adjusted of regulation chamber 21 can cause the problem of the intensity decreases of rotating shaft 20.

Be staggered setting axially back and forth, and the regulating part 40 is first partially opened when being moved back to front along the regulation chamber 21 or opened completely
Position flowing hole 25 rearward, then partially open or cutoff hole 23 that fully open position is forward, before being rested against by contraposition
The aperture regulation of cutoff hole 23 realizing the regulation of damping force, need exist for explanation be flowing hole 25 with cutoff hole 23 before and after phase
Mistake is set, and can be that front and rear setting of staggering completely is no staggeredly, and now, the regulating part 40 is moved axially along the regulation chamber 21
When first fully open position flowing hole 25 rearward, then partially open or cutoff hole 23 that fully open position is forward, also may be used
To be flowing hole 25 and cutoff hole 23 partly overlaps settings of staggering, now, the regulating part 40 is along the axially shifting of the regulation chamber 21
First partial open position flowing hole 25 rearward when dynamic, then the forward cutoff hole 23 of partial open position, then complete open position
Flowing hole 25 after resting against, the forward cutoff hole 23 in last fully open position, so can also realize the purpose of this utility model,
Here repeat no more.
The present embodiment is to realize unidirectional damping effect by setting the plectrum 50 that can be rotated on the inwall of housing 10, certainly
It is also possible that plectrum 50 is fixedly installed on the inwall of housing 10 to realize the effect of bidirectional damper, regulation of the present utility model
Mechanism is equally applicable to this kind of damper of form.
Described above has shown and described preferred embodiment of the present utility model, as previously described, it should be understood that this practicality is new
Type is not limited to form disclosed herein, is not to be taken as the exclusion to other embodiment, and can be used for various other groups
Close, change and environment, and can be in utility model contemplated scope described herein, by above-mentioned teaching or the technology of association area
Or knowledge is modified.And the change and change that those skilled in the art are carried out do not depart from spirit and scope of the present utility model, then
All should be in the protection domain of the utility model appended claims.
