For further perfect, on mounting panel, be rotatably connected to keeper, the upper end of keeper is provided with the Access Division of blocking driven wheel, and the lower end of keeper is provided with top and is pressed in the top splenium on banking stop.The centre of keeper is rotatably connected on mounting panel by torsion spring, after rotating shaft inwardly promotes, be subject to the twisting force of torsion spring to make the Access Division on keeper move up and be connected on driven wheel, driven wheel is fixed can not rotate, circuit breaker is in the time of control circuit like this, regulator cubicle door, in locking state, cannot be opened; And in the time that rotating shaft outwards promotes, banking stop outwards moves and pushes up the top splenium that is pressed in keeper lower end, make Access Division depart from driven wheel, rotating shaft and driven wheel are in transmission connection and drive transmission roller to rotate.
Housing outer bottom is provided with contact, and one end of contact is movably connected on housing, is connected with push rod on contact, and push rod stretches in housing, and transmission roller is provided with the projection that pushes up the bar that bears down on one.The effect of this contact is to press sensitive switch, and making current, and in the time that rotating shaft drives the rotation of transmission roller, the projection on transmission roller pushes up the bar that bears down on one, and contact making current is tested, and can test in the situation of opening cabinet door like this.
Banking stop is stuck in lower bayonet slot.Banking stop is along with rotational pin, bayonet lock rotate together with rotating shaft like this, produces wearing and tearing between avoiding mutually.
The effect that the utility model is useful is: the utility model reasonable in design; control the switch of the keying of regulator cubicle door and electric current; ensure current interruption in the time that regulator cubicle door is opened simultaneously; not only regulator cubicle is played to good control; and play a good protection; simple in structure firm, be conducive to extensive popularization.
