Description
Technical field
The utility model relates to a kind of cover plate Slow-falling device, applicable to lavatory lid.
Background technology
In the prior art, the cover plate of toilet (comprising seat ring and lid) is directly to be articulated on the toilet by pin, shown in Fig. 1,1A.Like this, when going to toilet, Chang Yin accidentally drops cover plate is hurtled down under the gravity effect, and cover plate and toilet bump, and send violent sound, if at night, and the anxiety that more has noise to wake from a dream with a start.
Summary of the invention
The purpose of this utility model is to provide a kind of cover plate Slow-falling device, to slow down the speed that cover plate falls, avoids making a noise.
To achieve these goals, solution of the present utility model:
A kind of cover plate Slow-falling device is made up of axle sleeve and axle core, and the two is airtight cooperation and forms annular seal space, is full of damping oil in the annular seal space; Form one in the axle sleeve with overhead gage; Form scraper plate on the axle core and stretch in the annular seal space, this scraper plate and its centre side are and closely cooperate existence one gap between the scraper plate outside and the sleeve lining; The direction that elastic doctor blade falls along cover plate, the place ahead are that moving type is between sleeve lining and the scraper plate outside and trailing edge is fixed on the scraper plate outside, Elastic Contact outside the elastic doctor blade and between the sleeve lining.
Be symmetrically formed two baffle plates in the above-mentioned axle sleeve, annular seal space is divided into two chambers by two baffle plates; Being symmetrically formed two scraper plates on the axle of axle core also stretches into respectively in two chambers.
Form a containing cavity in the above-mentioned axle sleeve vertically, this containing cavity by axle sleeve and axle on the core airtight cooperation of elastic doctor blade and be annular seal space; Jack is formed on the containing cavity bottom; The axle core is plugged in the containing cavity, and axle head passes jack and fixed by screw.The axle head of axle core also can pass jack, is plugged on the end cap, and fixes by screw.Axle sleeve is provided with sealing ring with the cooperation place of axle core, to guarantee airtight cooperation the between axle sleeve and spool core.
Above-mentioned elastic doctor blade is " L " font, and holddown groove is offered in the outside of scraper plate, one side being fixed in the holddown groove of elastic doctor blade, between the direction that the another side of elastic doctor blade falls along cover plate is extended and is in outside sleeve lining and the scraper plate.
The bottom of above-mentioned annular seal space forms an arc oil guide groove at the initial segment along the cover plate falling direction.The radian of this oil guide groove is 60-70 °.
Above-mentioned axle sleeve forms fixed strip outward, so that be fixed on the fixed head, so as to being fixed on the toilet.
Form fixed jack on the above-mentioned axle core, so that be fixed together with cover plate.
After adopting said structure, the utility model is made up of axle sleeve and axle core, is arranged on the articulated section of cover plate and toilet.During use, if accidentally drop accidentally, when cover plate stays under the gravity effect, meeting surrounds closed cavity because of sleeve, axle core and scraping blade, and produces very high oil pressure, and scraping blade and sleeve lining are close to, the damping oil constricted flow, thus the speed that cover plate falls slowed down, avoid making a noise.And when turning on the cover plate,, form the gap between elastic doctor blade and the sleeve lining because oil pressure makes the elastic doctor blade distortion, it is smooth and easy that damping oil flows, on turn over light.

Specific embodiment
As Fig. 2, cooperate shown in Fig. 3, the 3A, a kind of cover plate Slow-falling device that the utility model provides is made up of axle sleeve 1 and axle core 2.
Form a containing cavity 11 in the axle sleeve 1 vertically, be symmetrically formed two baffle plates 12 in this containing cavity 11 of axle sleeve 1, jack 13 is formed on containing cavity 11 bottoms, and containing cavity 11 bottoms form an arc oil guide groove 14 at the initial segment along cover plate 5 falling directions, and the radian of this oil guide groove 14 is about 60-70 °.The axle sleeve 1 outer fixed strip 15 that forms cooperates with stopper slot 31 by this fixed strip 15, and axle sleeve 1 fixedly is plugged on the fixed head 3, is fixed on toilet 4 by fixed head 3 again, makes axle sleeve 1 be fixed on the toilet 4 thereupon.
Axle core 2 is plugged in the containing cavity 11 of axle sleeve 1, and axle head passes jack 13, is plugged on the end cap 21 again, and is fixing by screw 22 then, a core 2 can be rotated in the containing cavity 11 of axle sleeve 1, but can not come off from containing cavity 11.Axle sleeve 1 is equipped with sealing ring R with the cooperation place of axle core 2 and the cooperation place of axle sleeve 1 and end cap 21, to guarantee that axle sleeve 1 cooperates with axle the airtight of core 2, and make containing cavity 11 be annular seal space by this airtight cooperation, be full of damping oil (the band point partly is damping oil among the figure) in the annular seal space.Be symmetrically formed two scraper plates 23 on the axle of axle core 2, be in respectively between two baffle plates 12, and the central side of scraper plate 23 and baffle plate 12 is and closely cooperates, like this, annular seal space is divided into two chambers by two baffle plates 12, two scraper plates 23 stretch into respectively in two chambers, have a gap between containing cavity 11 inwalls of scraper plate 23 outsides and axle sleeve 1, and holddown groove 231 is offered in the outside of scraper plate 23.Elastic doctor blade 24 is " L " font, direction along cover plate 5 whereabouts, the back of elastic doctor blade 24 is fixed in the holddown groove 231, the front of elastic doctor blade 24 is extended and is between containing cavity 11 inwalls and scraper plate 23 outsides of axle sleeve 1, and Elastic Contact between containing cavity 11 inwalls of elastic doctor blade 24 outsides and axle sleeve 1.Form fixed jack 25 on the axle core 2 in addition,, relend and help axle sleeve 1 and axle core 2 to cooperate, promptly make cover plate 5 be articulated on the toilet 4 so that be fixed together with cover plate 5.
When the utility model uses, shown in Fig. 4-8.
Initial period, as Fig. 4, cover plate 5 covers, and elastic doctor blade 24 is close to containing cavity 11 inwalls of axle sleeve 1.
On turn over the stage, as Fig. 5, turn on the cover plate 5 because the oil pressure that damping oil produces in the annular seal space makes elastic doctor blade 24 distortion, form the gap between containing cavity 11 inwalls of elastic doctor blade 24 and axle sleeve 1, damping oil can be smooth and easy mobile, turns over light on the cover plate 5.
Translate into a stage, as Fig. 6, translate into the position on the cover plate 5, elastic doctor blade 24 is close to again with containing cavity 11 inwalls of axle sleeve 1.
Fall the starting stage, as Fig. 7, cover plate 5 begins to fall, because these containing cavity 11 bottoms of axle sleeve 1 form an arc oil guide groove 14 at the initial segment along cover plate 5 falling directions, under the effect of this oil guide groove 14, though elastic doctor blade 24 is close to containing cavity 11 inwalls of axle sleeve 1, damping oil still can flow through by oil guide groove 14, damping oil still can smooth and easyly flow, and the 5 whereabouts starting stages of cover plate are light.
The whereabouts later stage, as Fig. 8, cover plate 5 continues to fall, because sleeve 1, axle core 2 and elastic doctor blade 24 surround closed cavity, damping oil in the closed cavity produces very high oil pressure, makes the elastic doctor blade 24 and containing cavity 11 inwalls of axle sleeve 1 be close to the damping oil constricted flow, cover plate 5 slowly falls, and avoids making a noise.
Need to prove: the number of baffle plate 12 and scraper plate 23 is the best with two, can also be one or three certainly, but the change of concrete number all should fall into this case category.
