Fig. 1 only expresses the part of the lid 2 of ceramic wc flushing cistern 1.Thickness A is owing to the reason difference of manufacturing and material is very big in this lid 2.In Fig. 5, represented a flushing water case lid 2 ', its thickness A ' much bigger.There is not the flushing water casing of expression preferably to make with pottery equally in the drawings, and porose in the bottom, the fixedly adapter 69 of discharging valve 80 in the hole.The manipulation of discharging valve 80 is undertaken by manipulation device 90, and manipulation device has a shell 4, and shell 4 is fixed on and covers in 2 the hole 3.Switch 72 is arranged in shell 4, can be by it by selecting raising rod 49 or promoting two pull bars 48 and 49 simultaneously.Only promote a pull bar 49 and cause full flushing, cause partial flushing and promote two pull bars 48,49.
Discharging valve 80 has a float shell 64, and float 65 and the valve disc 67 that is fixed on the float are in this shell.Valve disc 67 also thereby with valve is closed by being placed on the valve seat 68 in Fig. 1.Float 65 is connected with pull bar 49 with level and radially-protruding arm 53 by the person in charge 66, extension 70.When pull bar 49 promoted, float 65 had been with valve disc 67 to promote and thereby open discharging valve 80 and wash entirely.Fixed bearing 56 on float shell 64, and another root standpipe 73 is fixed the cup 63 of opening above on standpipe 73 in this bearing.Cup 63 is filled water and is played counterweight in the known manner.Arm 54 is fixed on the standpipe 73, and arm 54 is connected with pull bar 48.When promoting standpipe 73, meanwhile with water-filled cup 63 and equally with arm 53 and float 65 liftings by arm 54.After the flushing that discharges water, wherein there is the cup 63 of water to be pressed on the float 65, and thereby causes closing in advance discharging valve 80 as counterweight.Therefore only wash with the part amount of flushing water.
Therefore, just pull bar 49 and arm 53 and the float 65 that is connected with arm 53 by standpipe 66 are raised under the situation of full flushing.Under the situation of partial flushing, also make pull bar 49 and thereby float 65 and counterweight lifting with cup 63 by pull bar 48.For raising rod 49, on the pin 31 of shell 4, adorn a bottom lever 40 by Fig. 1, an end of lever 40 acts on the pull bar 49, with its other end and following lever briquetting 20 engagements.The design of lever 40 is identical with second lever 39, and second lever 39 acts on the pull bar 48 and is contained in pivotally on the fulcrum post 30 of shell 4.Lever 39 is in upper end and 19 engagements of lever briquetting.Figure 23 and 24 expression levers 39, such as already mentioned, it can have identical design with lever 40.This double-arm lever 39 is established a carrying sleeve 41 that smooth hole 42 arranged.Hole 42 is used to install the fulcrum post 30 that is illustrated in Figure 20, and fulcrum post 30 detachably is fixed in the screwed hole 33 (Figure 19) of lower casing part 6.Last driving lever 43 is located at the below of the pusher dog 24 (Fig. 9) of upper lever briquetting 19.If upper lever briquetting 19 moves downward, then lever 39 is around fulcrum post 30 revolutions.The hook-shaped pusher dog 44 of bottom from below act on the top hook-shaped end 48A (Fig. 1) of pull bar 48.Pull bar 49 is raised when lever 39 revolutions.As shown in Figure 1, two levers 39 and 40 stacked up and down.Lever 40 is contained on the pin 31, is in fulcrum post 30 belows on the lower casing part 6 by Figure 29 pin 31.
Manipulation device 90 has a shell 4 as already mentioned like that, and shell 4 is fixed on and covers on 2.This shell 4 is made up of lower casing part 6 and upper housing portion 5.As shown in Figure 6, upper housing portion 5 comprises that a cup-shaped region 5b and one are formed in the narrower district of the cannula-like 5A of this district's downside, and the latter has external screw thread 5c and leads rib 21 by what Fig. 7 stretched out in the inboard.Press Fig. 7, the district 5b of figure is used for installing and guiding two buttons 7 and 8.
At the fixing pressing mechanism 11 of the downside of button 7, at the fixing pressing mechanism 15 of button 8 downsides.Press Fig. 2, button 7 is provided with less connecing pressure surface and be used for the triggering part flushing.Button 8 has bigger press surface, and is used for triggering flushing fully.Figure 10 to 15 is these two pressing mechanisms 11 and 15 of expression in detail.Two pressing mechanisms 11 and 15 are designed to shaft-like, guide in a through hole 5d movably with little gap in upper zone.Therefore, the cross section of through hole 5d is corresponding with the cross section of two pressing mechanisms 11 and 15.Pressing mechanism 15 has a through hole 17 in the head end 16 of bottom, and the afterbody 14 of a correspondence of pressing mechanism 11 is contained in the through hole 17 movably.The convex shoulder 11a of pressing mechanism 11 abuts on the convex shoulder 15a of pressing mechanism 15.If pressing mechanism 15 moves downward with ammonium button 8, then pressing mechanism 11 does not move.Otherwise if the pressing mechanism 11 on button 7 moves downward, then the engagement by convex shoulder 11a and convex shoulder 15a makes pressing mechanism 15 in company with motion.
Pressing mechanism 11 and 19 engagements of upper lever briquetting, pressing mechanism 15 and following lever briquetting 20 engagements.For this reason, lever briquetting 11 and 15 has a thread segment 13 or 18 respectively in a thinner part district.In the internal thread 22 that thread segment 13 screw-in upper lever briquettings 19 are represented in Fig. 8.Internal thread 22 has the axial length more much bigger than thread segment 13, this especially as seen from Figure 5 situation.Thread segment 18 screws in the corresponding internal thread 22 of following lever briquetting 20.Lever briquetting 19 and 20 is preferably designed so that identical.Based on the top different reach of having mentioned, these two lever briquettings 19 and 20 can downwards and move upward, and meanwhile keep obtaining screw-threaded engagement.Distance between lever briquetting 19 and 20 and two buttons 7 and 8 thereby can in a limited scope, adjust.Because this adjustability, can with lid 2 or 2 ' thickness A or A ' adapt.This especially can compare Fig. 1 and 5 and find out.In the lid 2 of pressing Fig. 1, these two thread segments 13 and 18 are in respectively in the lower region of lever briquetting 19 and 20.The much bigger lid 2 of the thickness of pressing Fig. 5 ' in, these thread segments are in the upper zone of two lever briquettings 19 and 20.
On the surperficial 29a shown in two lever briquettings 19 and 20 are pressed against in Figure 19 by a compression spring 25 that is contained in lower casing part 6.For guiding lever briquetting 19 and 20 in the groove 29 of lower casing part 6, these lever briquettings have respectively that some extend laterally leads rib 19a (Fig. 9), and they insert in the corresponding guide groove 29b (Figure 19).When release button 7 or 8, lever briquetting 19 or 20 is always retracted position shown in Figure 1 again by spring 25.As especially as seen from Figure 22, groove 29 lateral openings.Two pusher dogs 24 stretch out from groove 29.Therefore these two lever briquettings, 19 and 20 removable and guidings in groove 29 un-rotatably.
Press Fig. 4, upper housing portion 5 is pre-assembled in by a nut 10 and covers on 2.Nut 10 has flange 9, and flange can abut in and cover on 2 the downside.Nut 10 play a part to cover 2 and discharging valve 80 between the kayser linkage.In order to connect upper housing portion 5 and lower casing part 6, the through hole 28 of a band internal thread 28a is arranged by Figure 19 latter.Therefore, spin mutually at these two housing parts 5 and 6 of confined state, meanwhile cannula-like zone 5a passes and covers 2 hole 3.Upper housing portion 5 abuts in and covers 2 upside, and lower casing part 6 goes up seamed edge 6a (Figure 19) with one and abuts in and cover 2 downside.Therefore shell 4 is fixedlyed connected with lid 2.It is different but two housing parts 5 can adapt for the thickness A with lid 2 with 6 spacing.Correspondingly, two pressing mechanisms 11 and 15 different depth ground screw in two lever briquettings 19 and 20.Compare two Fig. 1 and 5 and can be clear that this point.
In order to stablize discharging valve 80, on the lower casing part, plug the support 34 shown in Figure 16 to 18.Support 34 has two parallel and stretch limits 35 downwards, and they are formed on the baffle plate 36 of horizontal orientation.Baffle plate 36 has the mouth 38 of lateral open, and it is designed to correspond essentially to the flange 26 of lower casing part 6.Press Figure 19 to 21, flange 26 has a spur shape extension 32 at rear side, adorns a latch 27 that stretches out from downside on it.Latch 27 snaps in the breach of here can't see of strut rail 36.
Support 34 has three pins that protrude upward 37 on baffle plate 36, they abut in and cover 2 or 2 ' downside by Fig. 5.Therefore, support 34 is bearing in with spreading and covers on 2.Pass by visible lug 57 insertions in Figure 27 and 29 and fixing by a clamping device 45 respectively in order to make 80, two limits 35 of support 34 supporting discharging valves.Clamping device 45 respectively has two steady pins 46 and 47.If unclamp these pins, then support 34 can be infinitely along Height Adjustment.By pressing down the flushing water case lid, support 34 can be adaptive with the height of wc flushing cistern exactly.If reached appropriate position, just support 34 is fixed on the bearing 56 by two clamping devices 45.
Press Fig. 1, two pull bars 48 and 49 pass stacked guide member 55 up and down, and guide member 55 is fixed on the bearing 56.By means of clamping device 53, pull bar 49 detachably is connected with arm 53.By means of another clamping device 51 of same design, pull bar 48 equally detachably is connected with arm 54. Clamping device 50 and 51 unclamp and fixing realize by a turnover lever 52.If unclamp this two clamping devices 50 and 51, then two pull bars 48 and 49 can the stepless adjustment for the height that is adapted to wc flushing cistern.Therefore, discharging valve 80 and manipulation device 90 allow to be adapted to exactly the size of wc flushing cistern 1.Assembling can be implemented under the situation of instrument not having.
Establish a lid 60 on the float shell 64 for bearing 56 is fixed on, press Figure 28 and 36, lid 60 has two pivoted levers 62.These bar 62 kaysers are on the circumferential rib 64a shown in Fig. 1.Therefore, bearing 56 simply and detachably is fixed on the float shell 64.In addition, lid 60 is used for fixing standpipe 66.
