The left side of described I retainer rings is fixedly connected by screw with the gear shaft of drive gear.
The described side bonds yielding rubber of locked gear two；Locked gear is clamped at I together with two panels yielding rubber and consolidated
Determine between ring and II retainer rings, and two panels yielding rubber is adhesively fixed with I retainer rings with II retainer rings respectively.
The operation principle of the present invention：In the state that platform does not work or closes in stable, electromagnet does not work, and resets
Spring pulls locked rack to be engaged with locked gear, it is ensured that driver element output shaft can not be rotated, so that locked platform.In platform
When in running order (stable to open), work of electromagnet, powered motion iron core motion pulls link rotatable by circular shaft, so that
Locked rack is driven to rotate by rotating shaft, locked rack is opened with locked gear；Now driver element output shaft can be rotated, just
Often work.
Beneficial effects of the present invention：
The present invention reaches the effect of locked platform shafting by locked gear shaft, compared with direct locked platform shafting, this
Scheme has lightweight, the small advantage in required space.
The present invention fixes locked gear by yielding rubber, improves mechanism impact resistance, reduces locked gear
Size.Realize the opening of locked rack using lever principle and engage, reduce and back-moving spring is wanted with solenoid actuated power
Ask.
