Gap between said dissectible pin and the dissectible pin hole is preferably 0.5mm.

The connection structure of the contact heel group in action tooth bar and the outgoing mechanism can be the structure of existing switch machine; And the present invention provides a kind of preferred connection structure to be: like Figure 15 and shown in Figure 16; Said action tooth bar 21 is gone up the action tooth bar cylindrical protrusions 211 that is provided with through it and is connected a batch (-type) startup board 44, passes through this batch (-type) startup board 44 again and is connected with contact heel group 43 in the outgoing mechanism.

Like Figure 15, Figure 16, Figure 17 and shown in Figure 180; The connection structure of said action tooth bar 21 and two contact heel groups is: the track providing the throw rod assembly to slide is on the indication rod frame slideway 451 on the indication rod frame 45 said batch (-type) startup board 44 to be set; This track is provided with a fracture, and this slideway is separated into indication rod frame left side slideway 4511 and the right slideway 4512 of indication rod frame; The indication rod frame is installed on the cabinet.Batch (-type) startup board 44 places on the slideway 451 movably.On indication rod frame 45, be provided with two groups of break groups: break group a 421 is oppositely arranged with break group b 422 becomes one group, and break group c 423 and break group d 424 are oppositely arranged and become one group.On the indication rod frame, pass through contact heel group left side castellated shaft 4321 and contact heel group hinged respectively left contact heel framves 4311 of right castellated shaft 4322 and right contact heel frame 4312; Two contact heel framves and castellated shaft are fixed; Contact heel winding point is set on two contact heel framves, is used for and the break set of bond.On two contact heel framves, correspondingly being provided with left wheel 43111 respectively contacts with batch (-type) startup board 44 with right roller 43112.This batch (-type) startup board 44 that be provided with two contact heel groups on said the roller high-order contact surface 445 and the isometric low level contact surface 446 in its both sides that contact; Three sections contact surfaces are connected through domatic 447; Make when roller on each said contact heel group places high-order contact surface 445 and a break set of bond of a pair of break group, combine with this another break group when placing low level contact surface 446 the break group.

The connection structure of said action tooth bar 21 and batch (-type) startup board 44 is: establish a batch (-type) startup board elongated slot 442 at the moving direction of said batch (-type) startup board 44 upper edge throw rods 31, a column type that sets firmly on the said action tooth bar 2 protruding 211 can be arranged in this elongated slot 442 along elongated slot movably; A near hinged respectively interlock plate 441 these batch (-type) startup board 44 the above elongated slot two ends; When said interlock plate 441 is on said track; The end of itself and said elongated slot 442 lays respectively at said protruding 211 both sides and blocks said protruding 211 two moving directions in elongated slot 442 to block said column type protruding 211, makes this batch (-type) startup board 44 and said action tooth bar 21 same moved further; When said interlock plate hung in said fracture, said protruding 211 can move in said elongated slot 442, and said batch (-type) startup board is no longer moved.

The length of the said elongated slot 442 of startup board 44 can be corresponding with the reciprocating travel of said action tooth bar 21.

The interrelation of the length of said fracture length, high-order contact surface 445 and low level contact surface 446 is: when the contact point of the said contact heel group of a side and said batch (-type) startup board from the low level contact surface after high-order contact surface; The said contact heel group of opposite side and the contact point of said batch (-type) startup board also are positioned on the high-order contact surface; Said interlock plate can drop to just now in the said fracture and remove the fixing to said convexity, and the said interlock plate of this side is still in said fracture; When the takeoff output spare on the driver train promoted said batch (-type) startup board to a reciprocating side point, the contact heel group of opposite side and the contact point of said batch (-type) startup board were positioned on the low level contact surface of this side.

In the use, shown in figure 15, also be on the right endpoint of stroke at right locked position, the right roller 43112 on the right contact heel group places on the high-order contact surface 445 of batch (-type) startup board 44, and this contact heel group engages with break group d 424; At this moment, protruding 211 are positioned at the right-hand member of the elongated slot 442 on the batch (-type) startup board, and right interlock plate 4412 is connected as a single entity convexity 211 and batch (-type) startup board 44 with the right part of elongated slot 442 on slideway 451.At this moment, the left wheel 43111 on the left contact heel group places on the low level contact surface 446 of batch (-type) startup board 44, and left contact heel group engages with break group b 422.

During release, as shown in Figure 6, quadrant gear 22 begins to rotate counterclockwise; Action tooth bar 21 begins to be moved to the left the d1 distance, and the right-hand member of left groove contacts with left latch post 351, simultaneously; The left end of right groove 31b is corresponding with right latch post 352, and in this section miles of relative movement process, throw rod is not mobile; But action tooth bar 21 begins to move to left, and drives the batch (-type) startup board and moves to left; Left side contact heel group earlier along domatic from the low level contact surface to high-order contact surface, become contact promptly to break off and represent with break group a 421.The length of the distance of expression less than d1 is broken off in the motion of batch (-type) startup board, therefore, is to break off earlier and representes release again, meets the industry regulation of this area.

Then, as shown in Figure 6, the right-hand member of left groove promotes left latch post 351, and right latch post 352 is also come out from right breach, can be moved to the left with the action tooth bar, and the traction tongue moves.In this simultaneously, the fracture that right side interlock plate 4412 is come slideway 4512 falls, and protruding 211 continue to move to left in groove 442, and right interlock plate has been removed the incidence relation of convexity 211 with batch (-type) startup board 44, and batch (-type) startup board 44 stops to move.Meanwhile, as shown in Figure 5, the action tooth bar continues to move to left, and accomplishes the locking overall process.

Move to the left end of elongated slot 442 when convexity 211; Action tooth bar 21 has promoted left latch post and has got into left locking gap; Implement locking, then, promptly begin to promote the batch (-type) startup board and continue to move to left; And the moving plate 4411 of Left-wing Federation's this moment is come on the slideway 4511 from fracture, convexity 211 is constrained between moving plate of the Left-wing Federation and the groove left side make batch (-type) startup board and convexity become one again.And at this moment, the right roller 43112 on the right contact heel group is fallen on the low level contact surface, and right contact heel group changes into break group c 423 and engaging; At this moment; The promptly protruding left end point of coming stroke, and by conversion locking mechanism locking, and the circuit of the expression behind the locking has also just been connected.

Between conversion locking mechanism and the outgoing mechanism a mutual relation is arranged, that is:

The distance that moves to the corresponding said action tooth bar of high-order contact surface (21) on the low level contact surface; Difference corresponding to said groove length on the said action tooth bar (21) and said latch post diameter; Perhaps; Each end points of the reciprocating travel of said action tooth bar (21), on the end points of the reciprocating travel side of said throw rod assembly, growing one section, this segment distance is and makes the distance of contact heel group from moving to the said action tooth bar of high-order contact surface on the low level contact surface.

The difference of the length of the said groove on the distance that moves to the corresponding said action tooth bar of high-order contact surface on the said low level contact surface and the said action tooth bar and the diameter of said latch post is corresponding.

Distance between two locking gaps on the said track is the reciprocating travel of throw rod assembly, also is corresponding with the reciprocating travel of tongue or heart rail.And the reciprocating travel of action tooth bar 21 has increased a length respectively outside two end points of the reciprocating travel of throw rod assembly.When the throw rod assembly arrives locking gap; The roller of the contact heel group on the corresponding intermittently startup board, on the high-order contact surface and prepare to slide to the low level contact surface, the final stage of action tooth bar running stroke apart from the time; Roller slides into the low level contact surface, connects expression signal.Otherwise, will be when separating the locking state variation at the throw rod assembly from locking states, action tooth bar 21 moves a segment distance earlier; Make the contacts side surfaces latch post of the applied thrust on the groove, and the throw rod assembly moves not, moved but action tooth bar 21 drives intermittently startup board 44; Make the contact heel group from the low level contact surface to high-order contact surface; Promptly break off expression, then, action tooth bar 21 pushing action bar assembly just now begins to move.Promptly having realized connecting behind the first locking expression and county thus breaks off and separates locking after representing; Satisfy in switching process; Break off and represent that afterwards release again and locking provide the industry requirement of expression afterwards again; Throw rod and outgoing mechanism are organically combined, and throw rod is accomplished release-conversion-locking process, and the expression process is represented-provided in outgoing mechanism completion cut-out.

Describedly move the length of tooth bar 21 upper grooves and the difference of latch post diameter just apart from d or d1 (like Fig. 4 or shown in Figure 6).This length apart from d or d1 can not be too short; Otherwise; Throw rod under locking states, run in the normal range vibration also feasible solution unblank to close, still, this length apart from d or d1 can not be oversize; Otherwise will make that the reciprocating travel of action tooth bar 21 is oversize, and make the oad of entire equipment increase.

When action tooth bar 21 moved in the elongated slot of batch (-type) startup board, also the throw rod through conversion locking mechanism drive tractive tongue or heart rail moved.Action tooth bar motion and the motionless process of batch (-type) startup board is the process that throw rod tractive tongue or heart rail move.When the convexity 211 of action on the tooth bar 21 arrives an intermittently end of the elongated slot of startup board, when beginning to promote it and moving, promptly corresponding throw rod has also reached an end basically; The tongue or the heart base of the rail have originally put in place; Then, through changing locking mechanism with the throw rod locking, subsequently; The contact heel group that is exactly this side is connected expression from high-order contact surface slideway low level contact surface.The end points of the reciprocating travel of action tooth bar has also arrived.Otherwise the action tooth bar returns from this end points, is exactly that drive startup board at intermittence moves immediately; Make this end the contact heel group from the low level to high-order contact surface, this is to break off expression, and the contact heel group of the other end is still on high-order contact surface; Also be to be in the state that breaks off expression, at this moment, the action tooth bar continues to move; Drive promptly that throw rod hauls tongue or heart rail moves to another position, at this moment, intermittently startup board is just no longer mobile.That is: in the elongated slot that the column type protruding 211 on the action tooth bar 21 is plugged on the batch (-type) startup board.When under throw rod and tongue or the non-locking states of heart rail, column type protruding 211 can move in elongated slot 442, and the batch (-type) startup board is motionless.The startup board that drives the action of contact heel group in this and the prior art is the difference that essence is arranged along with action piece omnidistance motion in whole stroke.

At the moving high-order contact surface of contact heel group roller is that energized provides when representing to the low level contact surface down, should be rapid, otherwise problem such as electric contact arcing can appear, if the contact heel group still slides from domatic, just there is potential safety hazard.For this reason; Like Figure 17 and shown in Figure 180, two said domatic next doors that are connected said high-order contact surface and low level contact surface on the said batch (-type) startup board 44 respectively are provided with a quick-acting slice 443, promptly left quick-acting slice 4431 and right quick-acting slice 4432; It is hinged or be arranged on movably on the said batch (-type) startup board 44; Corresponding each said quick-acting slice 443 is provided with a retracing spring 4441 and retracing spring 4442 on said batch (-type) startup board 44, and it is against corresponding quick-acting slice, and makes the part of this quick-acting slice lean out said domatic; Form domaticly with domatic parallel another of original batch (-type) startup board, and this is domatic more steep.The wheel of said left and right sides roller is wide corresponding with these two domatic width sums, can while and two domatic contacts.

Like this, when roller from high-order contact surface whereabouts during the low level contact surface, the more steep domatic quick downslide that can constitute from quick-acting slice; And when roller from the low level contact surface when high-order contact surface rises; The spring that the compressing quick-acting slice supports makes and contracts behind the quick-acting slice, and roller promptly rises along original domatic on the batch (-type) startup board 44 more slowly; Can reduce jam like this, make that motion is more smooth and easy.
