Description
Technical field
This utility model relates to the opening and closing technical field of helicopter hatch door, especially relates to
And one open-and-close mechanism, lock and helicopter.
Background technology
Helicopter by body and lift (containing rotor and tail-rotor), power, transmission three is greatly mainly
The composition such as system and onboard flight equipment.Rotor is typically sent out by turboaxle motor or piston type
Motivation is driven by the machine driven system being made up of power transmission shaft and decelerator etc., it is possible to by
The counteracting force that blade tip jet produces drives.
Helicopter is substantially different from the another kind of aircraft of aircraft, its thrust, lift and
The realization handled all has bigger gap with aircraft.The outstanding feature of helicopter is to do
Constant motor-driven flies for low latitude (several meters), low speed (from the beginning of hovering) and heading
OK, particularly can be in little area place VTOL.Owing to these features make it have wide
Purposes and development prospect.Military aspect be widely used to air-to-ground attack, machine fall log in,
Weapon transport, logistics support, rescue of battlefield, reconnaissance patrol, commander's control, liaison,
Antisubmarine clearance, electronic countermeasure etc..Civilian aspect be applied to short-distance transport, medical aid,
Disaster relief lifesaving, emergency resuce, hanging device, geological prospecting, fire extinguishing of protecting a forest, aerophotography
Deng.
In prior art, the open-and-close mechanism of helicopter hatch door includes lock and lock box.Lock is arranged
On the doorframe of hatch door；Lock box is arranged on hatch door.Lock box include fixed plate, toothed wheel,
Torsion spring and rotating support arm；Breach is set in toothed wheel；Toothed wheel is connected to by axis of rotation

Breach coordinates, and hatch door is closed.User pulls steel wire rope, and rotating support arm rotates and toothed wheel
Departing from, toothed wheel rotates clockwise under the effect of torsion spring, and push out on lock convex
Rising until protruding parallel with breach, hatch door is opened.Drive while rotating support arm rotates and touch
Bar moves, and feeler lever touching microswitch, the signal that hatch door is opened by microswitch passes to drive
Sail room, complete opening of hatch door.When hatch door is closed, projection is pushed away by user towards breach
Dynamic, toothed wheel rotates counterclockwise, and rotating support arm rotates backward under the effect of torsion spring, and with
Toothed wheel card and, rotating support arm band movable feeler lever moves simultaneously, feeler lever depart from microswitch, micro-
Signal is passed to driving cabin by dynamic switch, completes the closedown of hatch door.
But, feeler lever of the prior art is connected with rotating support arm, the mistake that rotating support arm rotates
In journey, band movable feeler lever moves, so that feeler lever touches microswitch or removes microswitch,
This design structure is when hatch door is also not completely turned off, and feeler lever i.e. touches fine motion and opens
Closing, send shutdown signal, user cannot learn whether hatch door is closed tight or completely accurately
Opening, therefore, it is the most accurate that open-and-close mechanism of the prior art makes hatch door closed position control.
