Preferably, described moving electrode downside is provided with a double contact switch, and described double contact switch includes main contacts and auxiliary contact, and the spacing between described auxiliary contact and the stationary electrode is less than the spacing between main contacts and the stationary electrode.
The beneficial effects of the utility model are:
Embodiment moving electrode of the present utility model is by adopting elasticity or adding the electric conducting material of elastic force, make moving electrode keep linking to each other with drive unit with the good curved locking bar of making by elastomeric material with moving electrode that contacts of stationary electrode less than the curved locking angle of 90 degree in free state, finish the on off state self-locking of moving electrode, reach the purpose of antidetonation, because the self-lock ability of moving electrode has also reduced the control requirement to drive motors.
Below in conjunction with accompanying drawing the utility model is described in further detail.
Description of drawings
Fig. 1 is first embodiment that the utility model provides.
Fig. 2 is second embodiment that the utility model provides.
Embodiment
First embodiment is with reference to figure 1, present embodiment includes direct current machine 3, the drive unit that worm screw 4 and the turbine 5 that cooperates are with it formed, and the moving electrode 2 that is attached thereto, and supporting with it stationary electrode 1, wherein, described moving electrode 2 is made by elastic conducting material, contact with stationary electrode 1 well in reset condition, the curved locking angle＜2 of the curved locking bar of moving electrode keep about 40 degree in reset condition, vertical rod 25 length of the curved locking bar of moving electrode are slightly larger than the maximum distance of the axle center of (1.1 times) turbine 5 to moving electrode 2, and the radius of the maximum distance of moving electrode 2 greater than turbine engage a gear 51 arrived in the axle center of turbine 5.
During concrete the action, engage a gear 51 on the drive unit turbine 5 is by curved locking bar push-and-pull moving electrode 2 actions of moving electrode, the curved locking angle＜2 maximums of curved locking bar during moving electrode 2 closures, turbine engage a gear 51 and turbine axle center are near level, produce cross force and very little upwards component, moving electrode 2 is disobeyed outer boundary strength by self elastic force with stationary electrode 1 good the contact; The curved locking angle＜2 of curved locking bar diminished when moving electrode 2 was opened, turbine engage a gear 51 is crossed turbine axle center vertical line left, to moving electrode 2 produce upwards, left bearing pressure, the downward elastic force of moving electrode 2 and the curved lock power of curved locking bar are selected in appropriate adjustment, make moving electrode 2 downward strength be not enough to overcome the curved lock power of curved locking bar, moving electrode 2 will be locked in this state and disobey outer boundary strength.
Second embodiment is with reference to figure 2, present embodiment includes direct current machine 3, driving gear set 4, the drive unit that output gear 5 is formed, and the moving electrode 2 that is attached thereto, and supporting with it stationary electrode 1, wherein, described moving electrode 2 is pushed down with stationary electrode 1 by shell fragment 6 in reset condition and is contacted well, the curved locking angle＜2 of the curved locking bar of moving electrode keep about 40 degree in reset condition, vertical rod 25 length of the curved locking bar of moving electrode are slightly larger than the maximum distance of the axle center of (1.1 times) output gear 5 to moving electrode 2, and the radius of the maximum distance of moving electrode 2 greater than output gear engage a gear 51 arrived in the axle center of output gear 5.
