As shown in Figure 3, the toggle switch 6 of this programme is installed in housing 7 sides of timer, the installation site is corresponding with reel cage 2 positions of timer inside, toggle switch 6 comprises and is positioned at stirring limit 601 and being positioned at the control limit 602 of housing 7 inside of housing 7 outsides, stir limit 601 and be connected limit 602 by brace 603 connections, the distance of stirring between limit 601 and the control limit 602 is identical with the thickness of housing 7, the length on control limit 602 is greater than the length of stirring limit 601, be provided with three grooves 606 in the inboard of housing 7, termination and groove 606 corresponding faces on control limit 602 arrange an arc projection 605 corresponding with groove shapes, the arc projections 605 that are stuck on toggle switch 6 its control limits 602 behind the housing 7 snap in the groove 606, make control limit 602 mobile between three grooves 606 by promoting to stir limit 601, realize the control of three kinds of operating states of timer.Control limit 602 is positioned on the side of housing 7, position near reel cage 2 is provided with two along the fixture block 604 of controlling the limit axially-aligned and keeping at a certain distance away, 602 opposite sides are provided with the fore-set 610 that turns clockwise for promoting pressing lever 202 on the control limit, pressing lever 202 at this programme mid cradle 2 can not directly contact with the contact 101 of sensitive switch 1, even reel cage 2 is timed an inserted sheet 501 and stirs and also do not reach contact 101, this programme has overlapped a slide block 607 that can move up and down along pressing lever 202 at the pressing lever 202 of reel cage 2, one side of slide block 607 is with the U-shaped groove, slip 607 utilizes the activity of U-shaped groove to be placed on the pressing lever 202, pressing lever 202 only has could be by lower contact 101 by slide block 604, one side of slide block 607 is provided with outstanding edge 608, edge 608 is stuck between two fixture blocks 604 on control limit 602, when toggle switch 6 moved, two fixture blocks 604 can haul edge 608 band movable sliders 607 and move at pressing lever 202.The front end of pressing lever 202 is provided with an outstanding skewback 609 with fore-set 610 corresponding sides, and the top of fore-set 610 is corresponding with skewback 609 inclined planes domatic 611.
Fixing slide 607 fixture block 604 can be replaced by a cylinder, the hollow circular-tube of edge 608 usefulness on sliding simultaneously replaces, and pipe is inserted the movable fixedly slip of cylinder, and slide block 607 is moved with toggle switch 6.In addition, slide block also can adopt the structure of Intermediate Gray through hole, as long as and poke rod between do not produce friction can.
Under said structure, for three grooves 606 on the housing 7, toggle switch 6 is realized the switching of three kinds of operating states of timer, is followed successively by from top to bottom long logical state, definition status and three kinds of working methods of long off status, and wherein the specific works process of each state is as follows;
One, long logical state:
Shown in Fig. 3,4, the arc projection that this moment, toggle switch was controlled on the limit is stuck in that groove of the top in the timer housing, pulling slide block in control limit moves to the top of pressing lever, in this process, fore-set on the control limit contacts with the skewback on pressing lever top gradually, pressing lever is turned clockwise under the domatic promotion of fore-set, and when the arc projection on the control limit snapped in the groove, fore-set also promoted pressing lever and presses the contact on the sensitive switch and keep down state.On this angle, drive link on the reel cage has also broken away from the track of timing point inserted sheet, even be provided with the timing point inserted sheet on the graduated circle like this, does not also affect reel cage, and sensitive switch also keeps down state always, and this state is fit to the timer not timing but the situation of load one direct power supply that connects.Pressing lever top among Fig. 4 is without skewback, but utilizes the mode of adjusting the fore-set height with pressing lever jack-up.
Two, definition status:
Shown in Fig. 3,5, the arc projection that this moment, toggle switch was controlled on the limit is stuck in that middle in timer housing groove, pulling slide block in control limit moves to the middle part of pressing lever, slide block is corresponding with the contact position of sensitive switch, pressing lever turned clockwise and drove simultaneously the contact of slipper push sensitive switch, and then realizes the break-make of electric current when the drive link on the timing point inserted sheet promotion reel cage this moment, under this state, timer can be realized normal load current break-make control.The front end of pressing lever can reduce the height of fore-set like this with skewback among Fig. 5.
Three, grow off status:
Such as Fig. 3, shown in 6, arc projection on this moment toggle switch control limit is stuck in the timer housing in that groove of below, pulling slide block in control limit moves to the end of pressing lever, pressing lever has certain swinging distance in the inside of slide block, slide block also has certain thickness simultaneously, pressing lever was pressed slide block at sensitive switch and was not contacted with the contact this moment, and the thickness of slide block is not so that pressing lever reaches the contact of sensitive switch yet, therefore when toggle switch is positioned at this position, timer just is in out-of-work state, and the load of connection also just is in off-position always.In Fig. 6, what slide block on the pressing lever adopted is that the through hole cover is inserted in the mode on the pressing lever, and the employing hollow circular-tube that is connected on slide block and control limit is enclosed within structure on the cylinder.
Timer is when long logical state, fore-set on the control limit is to contact and mutual the promotion by the inclined-plane with the skewback of pressing lever between the two, after the control limit arrives clamped position, skewback on the pressing lever also can apply a skew force that makes control limit rollback to fore-set always, after long-time, the arc projection just may withdraw from from groove, or timer also may withdraw from from groove at the situation arc lower projection that collides with, timer also just can not keep long logical state again, and the existence of this skew force, some junctions are disconnected or split, when overcoming this problem, usually adopt the methods such as clamping effect that strengthen the material diameter or strengthen arc projection and groove in the prior art, but comparatively speaking, the increase diameter can bring the trouble in the manufacturing, can bring the inconvenience of stirring and strengthen the clamping effect.
For above-mentioned situation, this programme is made a plane with the angle on skewback 609 hypotenuses and base, and this plane is parallel with pressing lever 202, simultaneously the top of fore-set 610 domatic 611 and the point that side intersects is also made the plane.When the inclined-plane of fore-set contact with the inclined-plane of skewback and mutually slide into the arc projection snap in recessed in after, both planes can fit together, under this state, it is exactly orthogonal active force between pressing lever and the fore-set, so not only stablized engaging of arc projection and groove, and the elastic deformation of whole toggle switch, the useful life of having improved toggle switch have been reduced.
Contact excessively naturally in order to make between slide block and the contact in addition, the top of contact is set to arc, and slide block also is made as radian near the angle of reel cage and relative one side with the contact, and both are when contacting like this, and slide block can be taken advantage of a situation the contact is pressed.
