Description

The Water charging drainage means (MG100) of flush toilet that is used for drawout cubicle

The utility model relates to a kind of low-voltage drawer cabinet, the operating mechanism of especially relevant drawer.

There is following shortcoming in existing Water charging drainage means (MG100) of flush toilet as the disclosed structure of Chinese patent CN2266210Y: 1, advance in the assembly to comprise the multi-stage gear transmission, because the error of aspects such as installation in use easily produces mechanical breakdown, make drawer pull and push difficulty; 2, electric travel switch is adopted in the test locking, in case this switch is short-circuited, the test locking is promptly malfunctioning, is easy to generate misoperation.

The purpose of this utility model is to provide a kind of drawer to pull and push laborsaving and can not produces the Water charging drainage means (MG100) of flush toilet of misoperation.

In order to achieve the above object, the utility model adopts following technical scheme: a kind of Water charging drainage means (MG100) of flush toilet that is used for drawout cubicle, have the assembly of propelling, test locking assembly and be connected the locking assembly, advance assembly to have the cardan shaft in hole with lock, screw propulsion roller and positioning disk are housed on this cardan shaft, and positioning disk engages with the location fastener; Test locking assembly has the gear that is contained on the cardan shaft, with the rack-plate of gears engaged, be fixed in the backup plate and the position indicator board of the band groove on the rack-plate, the rotatable shift fork that leans with backup plate, with the block of shift fork interlock, and be contained in driving lever on the switch lever; Connect the locking assembly and have the connecting lever that is contained on the switch lever, the connecting lever support with connecting lever and the hinged connecting rod of connecting lever support, with the locking plate of rod hinge connection, has on the locking plate and the corresponding hole of the lockhole of cardan shaft.

After adopting said structure, owing to advance assembly to have the cardan shaft in hole with lock, can directly insert with operating grip like this and turn cardan shaft and screw propulsion roller in the lockhole, save the multi-stage gear transmission, avoid mechanical breakdown, it is convenient and strength-saving that drawer is pulled and pushed; Test locking assembly has adopted mechanical structure, does not adopt electric travel switch, so can not produce misoperation; Have the locking plate that switch lever links in the locking assembly owing to connecting again, but the lockhole of this locking plate open and close cardan shaft, thereby realize connecting blocking function, can not produce misoperation.

Below in conjunction with drawings and Examples the utility model is described in further detail.

Shown in Fig. 1～4, the Water charging drainage means (MG100) of flush toilet that is used for drawout cubicle of the present utility model, have the assembly of propelling, test locking assembly and be connected the locking assembly, advance assembly to have the cardan shaft 10 in hole 9 with lock, screw propulsion roller 6 and positioning disk 4 are housed on this cardan shaft 10, and positioning disk 4 engages with location fastener 5; Test locking assembly has the gear 8 that is contained in cardan shaft 10, rack-plate 7 with gear 8 engagements, be fixed in the backup plate 12 and the position indicator board 14 of the band groove 13 on the rack-plate 7, the rotatable shift fork 15 that leans with backup plate 12, with the block 2 of shift fork 15 interlock, and be contained in driving lever 3 on the switch lever 1; Connect the locking assembly and have the connecting lever 18 that is contained on the switch lever 1, connecting lever support 20, the connecting rod 16 hinged with connecting lever 18 and connecting lever support 20, the locking plate 17 hinged with connecting rod 16 has the lockhole 9 corresponding holes 11 with cardan shaft 10 on the locking plate 17.On the position indicator board 14 position mark is arranged, the relevant position of holding on the drawer panel 21 is provided with watch window.The position mark of present embodiment is: I, separate; II, test; III connects.

Shown in Fig. 2,3,4, have the projection 27 corresponding on the shift fork 15 with the groove 13 of backup plate 12, an end of shift fork 15 is hinged on the drawer substrate 25; The middle part of shift fork 15 and block 2 adopts slide-bar and chute connected modes, can be to have chute as shown in Figure 2 on shift fork 15, and have slide-bar on block 2, also can be to have slide-bar and have chute on shift fork 15 on block 2.The other end of shift fork 15 has on pole 24 and the pole 24 spring 23 is housed, and an end of this spring 23 is resisted against on the substrate 25, makes shift fork 15 be subjected to a power of pressing to backup plate 2 all the time, so that push up mutually with backup plate 12.Have the chute 26 of rack-plate 7 and the open slot 22 that moves for driving lever 3 on the drawer bottom surface.Cabinet is provided with the alignment pin 28 that is slidingly matched with screw propulsion roller 6.Certainly, alignment pin 28 also can adopt another kind of fixed form, also promptly is fixed on the travel(l)ing rest that main and auxiliary plug-in unit is housed of drawer, and at this moment, the installation direction of screw propulsion roller 6 need change 180 °.

Shown in Fig. 1,5,6, also be provided with the limiting block 19 of limiting rod 16 pivot angle degree on the connecting lever support 20.

As shown in Figure 7, residing to separate, test and be connected three positions corresponding with drawer respectively in the position that has 29, three draw-in grooves 29 of three draw-in grooves on the positioning disk 4, and location fastener 5 comprises card body 31 and the elastic chuck 30 that is fixed on the drawer.

When the utility model uses, as shown in Figure 2, when drawer is in the separation point position, the available action handle inserts the lockhole 9 of cardan shaft 10, and at this moment, shift fork 15 pushes up with the planar portions phase-splitting of backup plate 12, block 2 stretches to open slot 22, blocked the direction of advance of driving lever 3, thus can not rotating switch joystick 1, and promptly switch can not close a floodgate; As shown in Figure 3, turn cardan shaft 10 with operating grip, screw propulsion roller 6 is rotated to move ahead, at this moment, rack-plate 7 is driven by gear 8 and has been moved to the left a segment distance, but the planar section of backup plate 12 still pushes up mutually with shift fork 15, block 2 still stretches to open slot 22, blocked the direction of advance of driving lever 3, switch still can not close a floodgate, and drawer at this moment is in test position; As shown in Figure 4, be rotated further cardan shaft 10, rack-plate 7 makes the groove 13 of backup plate 12 aim at the projection 27 of shift fork 15, owing to be subjected to the effect of spring 23 again to left lateral, projection 27 enters groove 13, shift fork 15 is swung forward, drives block 2 indentation forwards, has abdicated the advance route of driving lever 3, the panel inspection hole shows link position simultaneously, and turn switch lever 1 and just can close a floodgate this moment.As shown in Figure 5, when switch is in gate-dividing state, hole 11 on the locking plate 17 overlaps with the lockhole 9 of cardan shaft 10, expose lockhole 9, operating grip can put in lockhole 9, the rotating operation handle, can carry out the axle of drawer and insert operation, as shown in Figure 6, when drawer is in link position, after switch closes a floodgate, the connecting lever 18 that is connected with switch lever 1 is pushed locking plate 17 to by connecting rod 16 right-hand, staggers with the lockhole 9 of cardan shaft 10 in the hole 11 of locking plate 17, and operating grip can't stretch into lockhole 9, this just can't pull and push drawer, thereby has realized connection (combined floodgate) locking.When operating grip is forgotten 9 li of the lockholes of cardan shaft 10, because operating grip has stopped that locking plate 17 moves, switch lever 1 can not be rotated, thereby can't close a floodgate, prevented misoperation because of the charged extraction of switch combined floodgate drawer.
