Be in operation, first switch lever 1 is in effect with the adjusting axle journal 8 of its regulating arm 7 with the adjustment sheet 56 of middle second contact spring 52 and is connected.Therefore, the regulating arm 7 of first switch lever 1 stretches between the adjustment sheet 55 and 56 of two contact springs 51 and 52.
Two of the biswitch arm 12 of second switch lever 2 vertical or axially outstanding downwards adjustings refer to that 13 and 14 are in operation and are in effect with the first and second two contact springs 51 in the outside and 53 adjustment sheet 55 and 57 and are connected.Therefore, be in operation, regulate and to refer to that 13 are provided with adjustment sheet 55 direct neighbor ground, and adjusting refers to that 14 are arranged between two adjustment sheets 56 and 57.
Under installment state, the regulating element 42 of first governor motion 41 of adjustment (adjusting) lever 35 stretches between two contact springs 51 and 52.In this installation site, the regulating element 44 of second governor motion 43 of adjustment (adjusting) lever 35 also with adjusting range 15 direct neighbors of second switch lever 2.
In Fig. 4 to 7, the principle of work and power to time switch of the present invention is elaborated below now.
Fig. 4 illustrates the vertical view of two switch levers 1 and 2, this two switch lever stationkeeping ground and being bearing in revolvably on the common axis of rotation 3.In addition, as seen from Figure 4, biswitch star-wheel 20 closely be arranged on these two switch levers 1 and 2 near.Here, the switch of first switch lever refers to that 5 are meshed with the switching ring gear tooth 22 that is shown in broken lines of biswitch star-wheel 20.On the contrary, the switch of first switch lever 2 refers to that 11 are meshed with the second switch gear ring tooth 24 of biswitch star-wheel 20.Here in Fig. 4, first switch lever 1 at it along shown in effective position of the switch that the direction of arrow 9 is shown.Opposite second switch lever 2 refers to shown in 11 its neutral positions of rabbeting in the switching ring gear tooth 24 at its switch.In this " position of the switch ", second switch lever 2 is in its neutral position.In addition, can see contact spring group 50 by Fig. 4, this contact spring group with its contact spring 51,52 and 53 or its adjustment sheet 55,56 and 57 be in interlocking position with two switch levers 1 and 2.
Adjustment (adjusting) lever 35 be set directly at these contact springs 51,52 and 53 near, described adjustment (adjusting) lever is in " 0 position " of its neutrality in Fig. 4.Here the bearing journal 36 above can seeing in Fig. 4, adjustment (adjusting) lever 35 can be in the mode of clamping around described bearing journal adjustment.The neutral position of adjustment (adjusting) lever 35 shown in Figure 4 here, the regulating element 44 of second governor motion 43 of adjustment (adjusting) lever abut in to regulate in the outside and refer on 13 the adjusting range 15.In addition, the adjustment sheet 55 of contact spring 51 also abuts in the inboard to regulate under the situation of pretension slightly and refers on 13.
As seen from Figure 4, first switch lever 1 because switch refers to that first switch lever is regulated axle journal 8 with it and abutted on the adjustment sheet 56 of contact spring 52 in the position of the switch of 5 the deflection that realizes of reclining.By the adjustment movement of first switch lever 1 finished in Fig. 4, the second middle contact spring 52 moves along the direction of arrow 63 thus.Be about to arrive or during up to " final position " of second contact spring 52 that arrives centre shown in Figure 4, two contact springs 51 in the outside and 53 refer to that via adjusting 13 and 14 remain in the position shown in Fig. 5 by second switch lever 2 under the situation of pretension.By direction " minimum " rotation (Fig. 4) of biswitch star-wheel 20 along arrow 27, switch lever 2 is discharged by switching ring gear tooth 24 impact types ground, and makes its switch refer to that 11 arrive the position between two switching ring gear teeth 24 shown in Figure 4 by the rotation opposite with arrow 9.Owing to refer to the switch motion of 2 this impact type by second switch, therefore its switch refers to that 13 also adjust on the contrary with arrow 62, and contact element 58 impact types of first contact spring 51 in outside ground and arrow 62 lift from the contact element 59 of second contact spring of centre on the contrary.Simultaneously, the adjusting of second switch lever 2 refer to 14 also impact type ground move on the contrary with arrow 64, thereby contact element 61 impact types of the 3rd contact spring 53 in outside ground enters with the contact element 60 of second contact spring 52 of centre and contacts.The second middle contact spring 52 is determined size with its adjustment sheet 56 here like this along the adjusting distance of the direction of arrow 63, that is, the adjustment sheet 57 of the 3rd contact spring 53 in the outside refers to that from the adjusting of second switch lever 2 14 lift.Guaranteed contact reliably between two contact elements 60 and 61 thus reliably.
This also means in addition, in the neutral position of adjustment (adjusting) lever 35, be provided with the automatic switchover of three contact springs 51,52 and 53 by biswitch star-wheel 20 and two switch levers 1 and 2 because adjustment (adjusting) lever 35 and two switch levers 1 with 2 and contact spring 51,52 and 53 be not in effect and be connected.
In addition, Fig. 5 illustrates two switch levers 1 and 2 can be realized automatic switchover on function second switch position.As seen, the switch of first switch lever 1 refers to that 5 are arranged between two adjacent switching ring gear teeth 22 of biswitch star-wheel 20, and is not in thus in the position of the switch of deflection among the figure.Opposite second switch lever 2 refers to that via its switch 11 directions along arrow 9 rotate in the position of its deflection, as shown in Figure 5 around turning axle 3 by a switching ring gear tooth 24.In the position of the switch of the deflection of second switch lever 2, the second switch lever refers to that by its adjusting 14 outwards push the 3rd contact spring 53 in the outside along the direction of arrow 64, at this moment, regulates and refers to that 14 are connected with adjustment sheet 57 effects of contact spring 53 for this purpose.
Refer to that 13 also move during along the direction rotation of arrow 9 together at second switch lever 2 owing to regulate, first contact spring in the outside is also along the direction deflection simultaneously of arrow 62.Because first switch lever 1 is in its " invalid " position, first switch lever is not in the adjustment sheet 56 of second contact spring 52 of centre with its adjusting axle journal 8 in the second switch position shown in Figure 6 of whole device and engages.This is because because the adjustment movement of second switch lever 2, second switch spring 52 passes through it towards the contact element 59 of first contact spring 51 and being pushed by the direction along arrow 63 with the contacted contact element 58 of this contact element of first contact spring.Realize reliable electrical contact between two contact elements 58 and 59 thus, and also realized the reliable electrical contact between two contact springs 51 and 52 thus.Because adjustment (adjusting) lever 35 is in its neutral intermediate switch position equally in Fig. 5, can be owing to adjustment (adjusting) lever 35 influences in switching process shown in Figure 5.Here can see in Fig. 5 that in this second switch position of contact spring 50, two contact springs 52 and two contact elements 60 and 61 of 53 have certain distance each other, do not electrically contact thereby do not exist here.
Fig. 6 illustrates the connection arrangement form of effective first position of the switch that is in adjustment (adjusting) lever 35 in the Figure 4 and 5.Here adjustment (adjusting) lever 35 rotates a predetermined anglec of rotation on the contrary with arrow 45.As shown in Figure 6, in described first position of the switch, the regulating element 42 of first governor motion 41 of adjustment (adjusting) lever 35 is in second contact spring 52 of centre and engages.The second middle contact spring 52 since the adjustment movement of regulating element 42 along the direction deflection of arrow 63, thereby the contact element 60 of the second middle contact spring 52 enters with the contact element 61 of the 3rd contact spring 53 in the outside and contacts.
Here regulate distance and determine size like this, that is, the adjustment sheet 57 of the 3rd contact spring 53 outside making refers to lift reliably on 14 from the adjusting of second switch lever 2.This means that in this position of the switch of adjustment (adjusting) lever 35, the adjustment movement of second switch lever 2 can not produce any effect to the 3rd contact spring 53 in the outside.Realized the lasting contact closure between two contact elements 60 and 61 of two contact springs 52 and 53 thus.In addition, size is determined in this deflection along arrow 63 of the second middle contact spring 52 like this, that is, make two contact elements 58 respect to one another and 59 of two contact springs 51 and 52 have reliable distance each other equally.
Thus, even in the inflection point of the direction along arrow 9 shown in Figure 6 of second switch lever 2, also prevent these two contact elements 58 and 59 contact reliably.In other words, in this first position of the switch of adjustment (adjusting) lever 35, with its oneself with respect to the position of the switch of contact spring 51,52 and 53 irrespectively, two switch levers 1 and 2 can not be realized switching function.
Fig. 7 illustrates the situation of switchgear in a position of the switch of adjustment (adjusting) lever 35 among Fig. 4,5 and 6, and in this position of the switch, adjustment (adjusting) lever enters the second switch position along the direction of the arrow 45 predetermined anglec of rotation of moving.Can see that in described second switch position, second switch lever 2 refers to that by its adjusting 13 adjusting range 15 is by the direction deflection along arrow 9 of the regulating element 44 of second governor motion 43 of adjustment (adjusting) lever 35.Here this deflection is obviously greater than the deflection of switch lever among Fig. 52.Therefore, switch refers to that 11 also lift from switch star-wheel 20 or switching ring gear tooth 24 significantly.In this position of the switch of adjustment (adjusting) lever 35, refer to that by adjusting 13 move such degree with first contact spring 51 in the outside along the direction of arrow 62, make and between two contact elements 58 and 59, realize contact reliably.In addition, the 3rd contact spring 53 in the outside be deflected to such size, that is, two contact elements 60 of second contact spring 52 in the middle of making and the 3rd spring 53 in the outside and 61 no longer are in contact with one another.This refers to that by the adjusting of adjustment disk 57 by second switch lever 2 14 deflections that take place realize.The size of deflection described here is selected like this, makes the switch lever 1 of winning no longer can regulate axle journal 8 with it and is connected with second adjustment sheet 56 of opening spring 52 effect of entering of centre.
Can see that in the second switch position of adjustment (adjusting) lever 35, as shown in Figure 7, biswitch star-wheel 20 can not apply any on-off action to switch lever 1 and 2.Thus, in the described second switch position of adjustment (adjusting) lever 35, guaranteed the connection that contact spring group 50 is lasting reliably.
