Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail.
As shown in Fig. 1～4, the utility model comprises switching mechanism panel 2, switch knob 5 and earthed switch handle 8, and described earthed switch handle 8 is positioned at switch knob 5 belows.Wherein, described switching mechanism panel 2 is groove shape, and both sides cell wall all outside groove bending form the fixedly platform of use.In the groove of switching mechanism panel 2, be provided with switch knob slideway 1 and earthed switch slideway 12.
Described switch knob 5 comprises the locking plate for pulling and is arranged on the base 4 that also can move along described switch knob slideway 1 in the groove of switching mechanism panel 2, and described base 4 is in the process moving along switch knob slideway 1, and the locking plate of described switch knob 5 remains the state perpendicular to the groove inside bottom surface of switching mechanism panel 2.In the base 4 of switch knob 5, be relatively set with two square platforms, the switch tentacle of killer switch 3 is inserted in the space between described two square platforms, like this, when switch knob 5 is left behind or pushed to, just can drive the switch tentacle closure or openness between described two square platforms.
Described earthed switch handle 8 comprises the locking plate for pulling and is arranged on the base 9 that also can move along described earthed switch slideway 12 in the groove of switching mechanism panel 2, and described base 9 is in the process moving along earthed switch slideway 12, and the locking plate of described earthed switch handle 8 remains the state perpendicular to the groove inside bottom surface of switching mechanism panel 2.In the base 9 of earthed switch handle 8, be provided with fixed axis 13, interlock 7 is installed on fixed axis 13.Base 9 outside lower surfaces at earthed switch handle 8 are welded with earthing 11, and when earthed switch handle 8 is left behind, earthing 11 contacts with ground wire.
In the groove of described switching mechanism panel 2, between the base 4 of switch knob 5 and the base 9 of earthed switch handle 8, be provided with a transverse slat, described transverse slat is provided with for holding the magnet 6 of switch knob 5, in the lower end of switching mechanism panel 2, is also provided with magnet 6, for holding earthed switch handle 8.Between the groove inside bottom surface of switching mechanism panel 2 and the base of switch knob 5 and earthed switch handle 8, be provided with interlock plate 10, on this interlock plate 10, have the slotted hole that the locking plate for described switch knob 5 and earthed switch handle 8 passes.This interlock plate 10 hangs on the locking plate of switch knob 5, and this makes this interlock plate 10 can leaving behind or push to and move between the groove inside bottom surface of switching mechanism panel 2 and the base of switch knob 5 and earthed switch handle 8 along with switch knob 5; When switch knob 5 and earthed switch handle 8 are left behind simultaneously or push to simultaneously, slotted hole length on interlock plate 10 just in time makes the locking plate of described switch knob 5 pass from the top of described slotted hole, make locking plate the passing bottom from described slotted hole of described earthed switch handle 8, this has guaranteed when earthed switch handle 8 is left behind, the position that switch knob 5 can not be in being brought to.
When switch knob 5 and earthed switch handle 8 are left behind simultaneously, the magnet 6 on switching mechanism panel 2 holds respectively switch knob 5 and earthed switch handle 8.If earthed switch handle 8 is not brought to, switch knob 5 can not pushed to easily, because due to the effect of interlock plate 10, now needs very large power to overcome to hold the magnetic force of the magnet 6 of earthed switch handle 8 and switch knob 5 simultaneously.After having overhauled, should first earthed switch handle 8 be pushed to separatedly with ground wire, switch knob 5 just can be pushed at an easy rate.
When switch knob 5 is pushed to, if earthed switch handle 8 is brought to, blocking lever 16 through the sidewall of base 9 and the cell wall of switching mechanism panel 2 of earthed switch handle 8, as shown in Figure 5, makes earthed switch handle 8 in locking state simultaneously.Only have when switch knob 5 is left behind, the described blocking lever 15 of depressing is owing to being depressed and retracting by switch knob 5, and drive locking plate 14 to rotate, and then drive blocking lever 16 to extract out from the cell wall of switching mechanism panel 2, but blocking lever 16 still passes the sidewall of the base 9 of described earthed switch handle 8, as shown in Figure 6, now, earthed switch handle 8 just can move in the groove of switching mechanism panel 2.When earthed switch handle 8 is pushed to again, if switch knob 5 is also brought to, due to the reset response of spring 17, blocking lever 16 passes again the sidewall of base 9 and the cell wall of switching mechanism panel 2 of earthed switch handle 8 simultaneously so.
Operation principle of the present utility model is:
As shown in Fig. 7～8, operating personnel, when maintenance, should first be left behind switch knob 5 in a minute position, and the earthed switch handle 8 of simultaneously leaving behind, in co-bit, makes the earthing 11 on earthed switch handle 8 contact with ground wire, to guarantee operating personnel's safety.Due to interlock plate 10 and magnet 6 effects, if earthed switch handle 8 is not pushed to, switch knob 5 can not pushed to easily, has effectively prevented that switch knob 5 from, owing to surprisingly encountering and being brought to energising, further guaranteeing operating personnel's safety.During normal operation, earthed switch handle 8 is pushed in a minute position, due to the effect of interlock 7, by locked, only have when switch knob 5 and leaves behind when dividing position, and earthed switch handle 8 just can be left behind.
