21 and 22 earlier, this is two groups of coils; The head and tail of coil is connected with power panel 25.Because the direction difference of these two groups of coil powers, also different when the logical magnetic direction that is produced when going up electric current, when by power panel 25 energisings, just there is electric current to flow through in the coil.An iron core 27 is arranged in the coil, and one of this iron core is stretched in the coil, and the other end is connected with a connecting rod 30, and the other end of connecting rod 30 has tooth 33, and a circular protrusions 32 is arranged near the middle part of connecting rod.Track energising device for the path energising of the track for a train in base plate 1 front is arranged on the next door of connecting rod 30, it comprises an energising plate 40, a tripod iron plate 50 that is rotationally connected with these plate 40 centers is arranged above, an elongated slot 52 that cooperates with circular protrusions 32 is arranged on the pin sheet 51, when connecting rod 30 moves forward and backward, drive also movement therewith of pin sheet 51, having driven tripod iron plate 50 again simultaneously is that rotate in the axle center with center 54.Four angle end live wires of energising plate 40 pass rail base plate 1 and join with track path shown in Figure 1, so that switch on for path.For example, the electric wire on the

angle end

55,56 links to each other with the railway line of turnout C, A, and

angle end

57,58 then joins with the path of turnout C,

B.Angle end

55,56 and

angle end

57,58 join with the both positive and negative polarity of power supply respectively.Information for transfer operation person, moving of the mobile terminal 15 of the track switch 10 in control track front, transmission component also has a transmitting gear 60 to be installed in the next door of connecting rod 30 except connecting rod 30, and the tooth on this transmitting gear 60 just in time is meshed with tooth 33 on the connecting rod 30.The prominent axle 61 that an off-centre is arranged on gear 60, be used for lever 70 on elongated slot 71 match.The place near the other end of lever 70 also has a pivot slot 72, is used for and the fulcrum 73 that is fixed on the base plate 1 matches.End at push rod 70 is elastic steel wire 80, and the other end of this steel wire 80 is connected with the mobile terminal 15 of the track switch 10 in toy track front by the elongate slots 18 on the base plate 1.

3,4 explain operating principles in conjunction with the accompanying drawings more below.See Fig. 3 earlier, when being coil electricity, just have electric current to pass through in the coil, just produced magnetic field in the coil by energising plate 25.Under the effect of this magnetic field force, attracted iron core 27 to move to the direction of turnout A, B, driven connecting rod 30 simultaneously and also moved towards equidirectional.Because the tooth of connecting rod 30 front portions is meshed with the tooth on the transmitting gear 60, so gear 60 just rotates eccentric prominent axle 61 sides that forward near connecting rod 30 thereupon.Because the pivot slot 72 of push rod 70 is fixing on fulcrum 73, according to lever principle, the steel wire 80 of the other end of push rod 70 just court leaves a lateral movement of connecting rod 30, and makes the track switch mobile terminal 15 in the track front that is attached thereto also shift to same example again.From front elevation, just train travels on track B turnout.Simultaneously, backward under the migration, also along with move backward, drive tripod iron plate 50 is that fixing point rotates with axle center 54 to pin sheet 51 at connecting rod 30.Two pin sheets link to each other with the

angle end

55,56 of energising plate 40 in addition, because

angle end

55,56 joins by the path of electric wire with the B both sides, turnout in front, so the energising of the track of turnout B, train leaves for turnout C from turnout B, as Fig. 1, shown in 3 again.

Below we come the analysis operation person how to move the mobile terminal 15 on turnout 10 to a side again, and train is left on the main turnout C from turnout A.

Please see Figure 4, when opposite electric current for coil is logical by energising plate 25, just there is reversing the current to pass through in the coil, magnetic field force during fortune in the coil has promoted iron core 27 and connecting rod 30 moves to the direction of main turnout C, the tooth-like part of anything of connecting rod 30 front portions driven gear 60 again rotates, and makes eccentric prominent axle 61 forward the opposite side that leaves connecting rod 30 to.Again because push rod 70 is fixing on fulcrum 73, and the steel wire 80 of the other end of push rod 70 is just shifted to a side of connecting rod 30, and track switch 15 is in succession also together moved.From front elevation, just train travels on the A turnout of track.Simultaneously, under the effect that moves forward, pin sheet 51 is also along with moving forward at connecting rod 30, and driving tripod iron plate 50 is fixing point rotations that commutate with axle center 54, thereby two pin sheets link to each other with the

angle end

57,58 of the plate 40 of switching in addition.Owing to the turnout A of

angle end

57,58 by electric wire and rail front joins, so the energising of the track of turnout A, train leaves for main turnout C from turnout A, shown in Fig. 2,4 again.

Characteristics of the present utility model are owing to adopt the pinion unit flexible steel wire 80 of tool of unifying to move track switch 15, press a button even the operator has forgotten during to track switch at train vibration influence, have forgotten just and moved track switch that train can not overturn yet.For example, when track switch 10 was in position shown in Fig. 1,3, train left for the C turnout from the A turnout, and the operator has forgotten and moves turnout 15, because the elasticity of steel wire 80, the wheel of train forces track switch mobile terminal 15 to be moved towards E limit path, makes train be unlikely to overturn.In like manner, when track switch 10 was in position shown in Fig. 2,4, train left for the C main stem from the B turnout, is forgetting under the situation of moving mobile terminal, turnout 15, the wheel of train also can force track switch mobile terminal 15 to be moved towards the direction of arrow D, train is changed smoothly and does not overturn.

In addition, in order to overcome in the prior art, during owing to operation, the user connects push button for a long time, makes coil produce high temperature, and causes the situation of the control box fusing of plastic production to occur, and the utility model has adopted the control box that can power to be connected with electric current plate 25 in limited time.Ask for an interview Fig. 5 control box circuit diagram.Owing to adopted the capacitor C 1 and the C2 that can discharge in turn and charge, make also power supply (being shorter than 0.5 second) in limited time in turn of two output current P1 and P2, that is to say that in control box one group of electric current input is arranged, two groups of electric current outputs.Circuit is by C1, and the C2 charging of discharge is controlled electric current and exported.As pushing switch to another side, the C1 that has charged can discharge, and makes one group of output, and capacitor C 2 chargings, and when switch is pushed back, the electric charge that fills can be emitted and be made another group output.After electric current was connected, to the C1 charging, the C2 discharge of charging made wherein one group of electric current output services; As pushing switch to another side, to the C2 charging, charged C1 discharge, another group electric current output services.Charged capacitor discharge (being shorter than 0.5 second) to a certain degree the time, this group electric current promptly stops output, like this, avoids long and the high temperature and the danger that produce of conduction time, has overcome the problem of easy appearance of general traditional track switch.

Certainly, the switch apparatus of also available manual mode of operation track for a train, as load onto a manual toggle 100 on connecting rod 30, operator link moves forwards or backwards, and changes work thereby finish train.
