The specific embodiment
The a complete set of drainage fitting of representing among Fig. 1 has the draining valve 3 that comprises draining valve shell 4, and draining valve shell 4 is taken over a draining of stretching downwards at the end 31 that 7 places are fixed on wc flushing cistern container 30.This container 30 constitutes wc flushing cistern 1 with flushing water case lid 2, especially Tao Ci wc flushing cistern.
Draining valve 3 has a seal 5 as usual, and it can promote in order to discharge flushing by control button 9 seals 5 by being placed on the valve seat 6 in illustrated position.Preferably establish another second button here, so allow full flushing or partial flushing in the known manner.For promoting a counterweight and a seal 5 of not representing in the drawings, partial flushing loaded by this counterweight, so seal 5 is just closed draining valve 3 before wc flushing cistern 1 is emptied completely.For lift-off seal body 5, it is connected with pull bar 18 by lever 23 in the top, and another lever 22 that is used for partial flushing is connected with seal 5 indirectly by Figure 14.Two levers 22 and 23 are separately fixed on pull bar 18 or 17.
Establish a manipulation device 8 for raising rod 18 or 17, it is contained on the flushing water case lid 2.The shell of manipulation device 8 has a shell upper 8b and an outer casing underpart 8a.Outer casing underpart 8a has a base 14, but two have the lever 11 of two kinds of colors to be contained on the base 14 respectively limited-rotary.When pressing by this or another button 9, make this or another lever 11 revolutions by the push rod 10a of transfer 10, and meanwhile raising rod 17 or pull bar 18.As shown in figure 11, the axle journal 11a who extends laterally that is shaped on each of two levers 11 presses Figure 11 axle journal 11a and detachably is connected with pull bar 17 or 18.As shown in Figure 7, pull bar 18 has an elongated hole 18b, and elongated hole is located at that upper arm 18a goes up and transverse to the vertical axis extension of bar 18.It is identical with pull bar 18 that pull bar 17 is designed to minute surface mapping ground.
Two pull bars 17 and 18 rotatably are contained in the bindiny mechanism 16, press Figure 15 and 16, and there is mount pad part 27 in bindiny mechanism 16, and its horizontal-extending also has a groove 28, inserts the base 14 of the shell of having mentioned the front 8 in the groove.In order to support two pull bars 17 and 18, there is a transverse wall 32 in bindiny mechanism 16 by Figure 15 and 16, and it has two support holes 32a.Pull bar 17 and 18 passes these support holes 32a.
Bindiny mechanism 16 is contained in the hollow cylinder leader 20, presses Figure 14, and leader 20 is formed in draining valve shell 4 sides and vertically connects.Especially as can be seen, how bindiny mechanism 16 is placed in this leader 20 and vertically passes this leader by Fig. 1 and 2.
Bindiny mechanism 16 is shaped on brake tooth 29 as shown in the figure in its outside, and it and two pawl springs that are in the relative position spring are respectively in braking projection 21a place's engagement.These two braking projection 21a couple together bindiny mechanism 16 with leader 20, make to move up or down bindiny mechanism by drawing or pressing.But pawl spring 21 spring ground deflections here.They automatically again kayser at terminal location.Under the height and position of expectation, bindiny mechanism 16 can fixedly connected with leader 20 by rotation brake bar 19, and thereby fixedlys connected with draining valve shell 4.
In Fig. 3 to 6, represented rotation brake bar 19 in detail.As can be seen, rotation brake bar 19 has a turn-button 19a in the upper end, and a pinion 19b is shaped on the turn-button.With a certain distance from the pinion 19b convex shoulder 19d that is shaped, it has the opposed stopping projection 19e that extends radially.Below convex shoulder 19d, rotation brake bar 19 is shaped on breaker slot line 19c, and they only extend around the part circumference of rotation brake bar 19 to press Fig. 6.As can be seen, rotation brake bar 19 all is shaped on this breaker slot line 19c from convex shoulder 19d to the lower end.Therefore, here brake tooth is made smaller tooth pitch.In order to support rotation brake bar 19, mount pad part 27 has the reed 26 of the superincumbent spring that is shaped by Figure 15 and 17, and it radially fastens convex shoulder as shown in Figure 1 on convex shoulder 19d.Fix the rotation brake bar 19 that this kayser is lived thus vertically, and owing to projection (backstop) 19e is arranged so can rotate 180 ° approximately in limited ground.Especially as shown in figure 14, targeting part 20 and bindiny mechanism 16 constitute a passage 24, and passage 24 is made of with the similar wall 20b that is in relative position the semicircular wall 25 of cross section.On this wall 20b inboard, be formed with stopping projection 20a.At a position of rotation of rotation brake bar 19, stopping projection 20a is engaged in the breaker slot line 19c.Therefore, bindiny mechanism 16 is fixed on the height of adjusting, and thereby is fixed on the leader 20 by this rotation brake bar 19.At another position of rotation, stopping projection 20a and breaker slot line 19c do not mesh, so can move freely in passage 24 at this position rotation brake bar 19.
In order to rotate this rotation brake bar 19, be formed in pinion 19b and pinion 18d (as shown in Figs. 7-9) engagement that is formed on the pull bar 18 above it.Pinion 18d constitutes the additional sections 18c that a quadrant shape extends radially, and it is formed in below the elongated hole 18b.Another root pull bar 17 has such pinion 17d equally, it and pinion 18d engagement as shown in figure 11.If rotation brake bar 19 is around the rotation of its longitudinal axis, then two pull bars 17 and 18 revolutions.Throw off thus or set up leader 20 respectively with lever 22 and 23 be connected.
Two pull bars 17 and 18 have breaker slot line 18f respectively by Fig. 7 on the criss-cross bar 18e of cross section, press Figure 10, and the breaker slot line only extends along the part periphery.Two pull bars 17 and 18 pass lever 22 or 23 hole 22a or 23a as shown in figure 14 respectively.Hole 22a and 23a are designed to, and when at position of rotation shown in Figure 11, pull bar 18 or 17 because projection 22b or 23b are engaged in one of them breaker slot line 18f, makes lever 22 fixedly connected with pull bar 18 or 17 respectively with 23 respectively.Be in position shown in Figure 12 as if two pull bars 17 and 18, then above-mentioned kayser engagement is cancelled, and pull bar 17 and 18 can longitudinally freely move in hole 22a or 23a.
Two pull bars 17 and 18 and rotation brake bar 19 be designed to now, they are fixing simultaneously or can freely adjust.Pull bar of in Figure 11, representing 17 and 18 position, not only pull bar but also rotation brake bar 19 equal kaysers.Therefore bindiny mechanism 16 fixedlys connected with leader 20, and thereby fixedlys connected with draining valve shell 4.Meanwhile, lever 22 is fixedlyed connected with 18 with pull bar 17 with 23.Rotation brake bar 19, leader 20 and bindiny mechanism 16 constitute linkage 15 with housing parts 8a, and it couples together manipulation device 8 and draining valve 3.
The following describes assembling process:
Cover at 2 o'clock taking off, draining valve 3 is fixed in the known manner at the end 31 of wc flushing cistern container 30.Linkage 15 and outer casing underpart 8a here are fixed on the draining valve 3.Present two pull bars 17 and 18 are turned back to position represented among Figure 12, in this position, as explained above, pull bar 17 and 18 and bindiny mechanism 16 can be along highly mobile.But because two projection 21a, bindiny mechanism 16 temporarily is fixed on the leader 20.Now bindiny mechanism 16 is moved on to upper position.Then, load onto flushing water case lid 2.Outer casing underpart 8a and bindiny mechanism 16 is moved down by it finally loads onto until flushing water case lid 2 in this case.To cover 2 now and take away, two pull bars 17 and 18 will be turned back to position represented among Figure 11 by rotation brake bar 19.Lever 11 is in this position and two pull bars 17 and 18 couplings, and as top illustrated fixedly connected mechanism 16.In addition, these two levers 22 are fixedlyed connected with 18 with pull bar 17 with 23.Relay loam cake 2 now and load onto upper valve shell 8b.Assembled a complete set of drainage fitting thus.Can check by same simple mode.By turning round rotation brake bar 19 and correspondingly turning round pull bar 17 and 18, bindiny mechanism 16 can throw off again.So bindiny mechanism can freely vertically move again.Important point is, linkage and two pull bars 17 and 18 revolution can be undertaken by rotatablely moving in the upper end of bindiny mechanism 16 and simultaneously.Needn't insert wc flushing cistern dearly for this reason or handle each member.
The following describes embodiment by Figure 19 to 30.
Draining valve 101 is contained in the wc flushing cistern 102, equally preferably ceramic wc flushing cistern of wc flushing cistern and the casing that comprises the end 104 and lid 103 that a part expression is here arranged.The end 104, can be different with height H between the flushing water case lid 103.This draining valve 101 can adapt to different height H as following also will illustrating.
Draining valve 101 has a valve housing 105, and it is made up of the hollow cylinder housing parts 106 of bottom, so-called tank (Bassin) and superincumbent part 111.By can upper part 111 detachably being fixed on the following housing parts 106 rotating truck dead lever 112.One window 107 is arranged on the housing parts 106 below, and after valve body 109 promoted, flushing water can also finally can flow in the flush toilet by the flushing bend pipe that window 107 is not represented in taking over 108 inflow figure below valve disc 110.Taking over 108 places, draining valve 101 detachably is fixed on by the nut of not representing among the figure at the end 104.Fix a balance weight body 113 on valve body 109, it allows to implement in the known manner partial flushing.The overflow of flushing water is undertaken by bleed off pipe 114, and bleed off pipe 114 is parallel to valve body 109 and protrudes upward.It is also contemplated that a kind of form of implementation, wherein valve body 109 constitutes bleed off pipe simultaneously.
Also promote balance weight body 113 for poppet body 109 and under the situation of partial flushing, establish two one control levers 125, they are fixed and are separately fixed in the top on one of two levers 134 with one of two levers 121 respectively in its lower end.In order to discharge flushing, can be by selecting lifting two one control levers 125 or only promoting one of them.For this reason, by selecting that the big button of representing among Figure 20 138 is moved downward, or two buttons 138 and 139 move downward simultaneously.
Button 138 and 139 is contained in the button shell 137 of manipulation device 141, and manipulation device 141 is contained in and covers on 103.In Figure 19, the action direction when arrow 140 expression buttons 138 and 139 should move downward for the release flushing.Button 138 and 139 can design arbitrarily.
Button 138 and 139 in the known manner with lever 134 mating reactions, lever 134 is contained in to be handled in the shell 135.Two levers 134 and two buttons 138 and 139 be connected and undertaken by the button pin that does not have expression among the figure.Button shell 137 is fixed together by being threaded and handling shell 135.Clamping piece 136 can carry out error compensation.As shown in the figure, button shell 137 is on the wc flushing cistern 103 upside 103b, and clamping piece 136 abuts on the downside 103a.
Handle shell 135 and lever 134 and be contained in the bindiny mechanism 150 of yoke shape or U-shaped, there are a bridge 129 and two connecting rods of separately making 117 in bindiny mechanism 150.In addition, two one control levers 125 are bearing on the bridge 129 movably.
Handling shell 135 has the flange of can't see on the figure in its lower end, and shell 135 is buckled in the groove 132 of expression in Figure 26 and 27 at the flange place.Therefore, handling shell 135 detachably is fixed on the bridge 129.
Two connecting rods 117 are designed to the rotation brake post, in their upper end the lever 119 that extends radially are arranged respectively, can make connecting rod 117 around its longitudinal axis revolution at the lever place.The tooth 120 that the bar of connecting rod 117 has the non-circular cross sections shown in Figure 26 b and many protrusions are arranged.As shown in the figure, tooth 120 is arranged relatively, and a regional 117a who does not have tooth is arranged between tooth.At connecting rod 117 corresponding position of rotation, tooth in lower region with pawl spring 123 engagements of the housing parts 111 on top, and in upper zone with brake tooth 149 engagements of bridge 129.Do not existed in this engagement of another position of rotation, so connecting rod 117 can be longitudinally moves with respect to the housing parts 111 on top.
The housing parts 111 on top is formed with two cover tubular lugs 115, and they respectively have a through hole 122 by Figure 24.Through hole 122 is designed to make connecting rod 117 can pass freely through these through hole 122 ground at a position of rotation and moves.Pawl spring 123 stretches into a braking projection 123a in the through hole 122 respectively as shown in figure 24.A position of rotation is braked projection 123a by meshing moving of locking connecting rods 117 with tooth 120 therein.As shown in figure 24, two lugs 115 are not along diameter but arrange at an angle alpha that each other this angle [alpha] is significantly less than 180 °.She Ji outstanding advantage is like this, above the housing parts 111 on top, exists bigger space to be used for pipeline and similar item except that connecting rod 117.Two one control levers 125 for example are located between two connecting rods 117 by Figure 21, thus obtain a kind of compactness and thereby need the structure in less space.
Two levers 119 are formed in the upper end of head 118, and head 118 outsides are smooth and cross section is circular as shown in the figure.A projection 148 is shaped below lever 119, projection radially protrude and with visible projection 147 in Figure 28 b and 146 mating reactions as described below: if lever 119 is in the position of representing with solid line among Figure 20, then connecting rod 117 can move in through hole vertically, thereby tooth 120 does not mesh with projection 123a.Therefore, at this position lever 119 radially to interior orientation.Projection 148 at this position kayser in projection 146 back.So above-mentioned position is locked, and lever 119 can only remove lock along clockwise direction in by the through hole 130 of Figure 28 b.Head 118 is by tooth 120 and tooth 149 engagements in through hole 130, and thereby connecting rod 117 fixing vertically in through hole 130.If lever 119 is turned back to the position that dots among Figure 20, then tooth 120 meshes with projection 123a and thereby makes connecting rod 117 fixing vertically at housing parts 111 places on top.Therefore in one of them position of two connecting rods 117, bindiny mechanism 150 can be infinitely along Height Adjustment, and in another position, the height of bindiny mechanism 150 is fixed.In this position that is fixed, connecting rod 117 is connected with tooth 151.In order to throw off, lever 119 turns round along counter-clockwise direction in Figure 20.These two gyratory directions are represented with four-headed arrow 145 in Figure 20.Along the counter-clockwise direction gyration time, lock vertically movably position, and kayser is lived fixing vertically position when gyration along clockwise direction.Therefore, disengagement and fixing by simple gyration realization, this gyration tool free can be implemented on lever 119 with hand.Can also find out without difficulty, be in a disengaged position or the permanent position actually.
Two one control levers, 125 1 sides are shaped on tooth 128, and they can fix equally basically steplessly.The lever 126 that is shaped in the upper end, lever has a lateral slot 127.Control stick 125 inserts respectively in the non-circular hole 144 of the lever 121 shown in Figure 22 and 23.If lever 126 is in the position of representing with solid line among Figure 20, this moment, lever 126 was generally along radially inwardly stretching, so tooth 128 and braking projection 141 engagements of representing in Figure 23.Therefore control stick 125 is fixed in the through hole 143 vertically.If lever 126 is turned back to the position that dots among Figure 20, this moment, lever 126 was generally along tangentially protruding, so tooth 128 is cancelled and allows control stick 125 to move vertically in through hole 143 with the engagement of braking projection 143.Above-mentioned gyration is represented with four-headed arrow 133 in Figure 20.Groove 127 is used for inserting respectively the transmission arm 134a of lever 134 by Figure 20.If lever 126 is in the position of representing with solid line among Figure 20, then lever 134 shape sealing ground and control stick 125 engagements respectively.Because control stick 125 does not have tooth 128 in the zone of bridge 129 now, so control stick is unfixing vertically for maneuvering motion in the through hole 142 of bridge 129.Therefore this two one control lever 125 can be pressed by the gyration of lever 134 and select single or common lifting.Correspondingly, one of lever 121 or two levers 121 and thereby make valve body 109 or balance weight body 113 is promoted with valve body.Under first kind of situation, discharge full flushing, and release portion flushing under second kind of situation.Therefore, in the present embodiment can be by selecting full flushing or partial flushing.But also can imagine a kind of form of implementation, wherein only establish a lever 134 and also only establish an one control lever 125.
The following describes each step when this draining valve 10 of assembling.
Draining valve 101 is gone into water tank inside taking off flushing water case lid 103 fashionable dresses, and is fixed in the known manner at the bottom of the wc flushing cistern on 104.Two connecting rods 117 and two one control levers 125 insert in the through holes 130 and 144.Lever 119 and 126 thereby be in a position that makes the loosening guiding of connecting rod 117 and control stick 125 in the lower end.Connecting rod 117 is guided by pawl spring 123 self-lockings ground in through hole 122.Even therefore also need certain power just can make bindiny mechanism 150 along highly mobile at loosening state.When assembling, make bindiny mechanism 150 be in the uppermost position of representing among Figure 20 now.Manipulation shell 135 and lever 134 are preferably pre-installed and are prepared.But button 134 and button shell 137 here separate.If draining valve 101 has been fixed at the end 104, then on water tank, loads onto and cover 103.Here abut in to handle on the shell 135 bindiny mechanism 150 is moved down, correctly settle until the flushing water case lid by downside 103a.Again take flushing water case lid 103 now away, connecting rod 117 and control stick 125 be respectively in the revolution of lever 119 or 126 places, and thereby bindiny mechanism 150 is fixed on this height.Connecting rod 117 is fixedlyed connected with the housing parts 111 on top now, and control stick 125 is fixedlyed connected with lever 121.Therefore highly fixing also can the revolution of lever 134 is used for the check flushing.Load onto flushing water case lid 103 now once more, and button shell 137 can load onto or screw on button 138 and 139, abut on the flushing water case lid 103 upside 103b until this shell.Obviously, for the height of adjusting bindiny mechanism 150 without any need for instrument.Under the situation of needs, for example bindiny mechanism 150 can dismantle and readjust in case of necessity when checking.As can be seen, bindiny mechanism 150 can be adjusted on the very big height of difference.Because tooth 120 and 128 is very thin, be stepless basically so adjust.Therefore, can adjust very accurately with clamping piece 136, and as top illustrated, however this adjustment can be very simple and quick.Because connecting rod 117 and control stick 125 can be distinguished in the top revolution, so needn't insert in the wc flushing cistern dearly during assembling.Because all part can be made by pressure injection technology with plastics, so draining valve 101 is not corroded.This draining valve 101 is particularly useful for the wc flushing cistern of ceramic body and ceramic cap composition, makes the king-sized error that cause because produce here.
