In locking process, bearing pin roof pressure dead bolt and the slippage of traction iron core lower end that is fixed on towed electromagnet is in the tongue mouth, and elastic locking mechanism locks dead bolt.In the dropout process, remove locking through handling elastic locking mechanism, and under the effect of dead bolt resetting device, dead bolt resets to dead bolt.
Wherein, the dead bolt resetting device comprises torsion spring, and torsion spring is installed on the dead bolt axle, and torsion spring one end is fixed on the dead bolt, and an end is stuck on the fixed magnet of towed electromagnet.Adopt torsion spring, it is simple in structure, and is easy to maintenance.
The preferred elastomeric locking mechanism comprises the dropout pull bar, and the dropout pull bar is fixed on the pull rod shaft, and the dropout pull bar is provided with extension spring and pull bar resetting device.
Wherein the pull bar resetting device can comprise release electromagnet for automatic frame mode, and dropout pull bar one end and release electromagnet are hinged.Also can comprise manual trip level for manual frame mode, manual trip level is installed on the base, and manual trip level inner end and dropout pull bar one end flexibly connect.
The traction iron core of towed electromagnet upper end can be fixed on the bottom of travel(l)ing rest through link plate among the present invention.Convenient installation, good integrity.
Compared with prior art, the present invention has following beneficial effect:
1, because the center of travel(l)ing rest bottom is equipped with the traction iron core of tractive electromagnet, and in the lower end of traction iron core snap close and tripping mechanism are set, have formed electromagnet center lock button mechanism, not only realized the center snap close, in light weight, reliability is high; And realized not having the operation of pressure, not power consumption, noiselessness.
2, owing to adopted dropout pull bar and the measure of dead bolt two-stage lever in the latching device, tripping force reduces greatly, is easy to realize no-voltage trip.
