Embodiment
Please refer to Fig. 1, the utility model embodiment provides a kind of portable type aircraft (not shown), for deliver people or
Cargo.100 structure of gangway ladder door draw off gear in it is simple, can carry out turning on or off operation manually, easy to operate fast
Victory, time saving and energy saving, human cost is low, high safety, and long service life is practical and efficient, and cost performance is high.The portable type aircraft includes
Body (not shown) and gangway ladder door draw off gear 100.Gangway ladder door draw off gear 100 is installed on body, gangway ladder door draw off gear
100 can stretch out body, and be resisted against on ground, and in order to which occupant goes on or off the plane, gangway ladder door draw off gear 100 can also be retracted
Body to realize the sealing of body, and reduces occupied space, in order to which portable type aircraft executes aerial mission.
Gangway ladder door draw off gear 100 includes doorframe 110, gangway ladder door 120, handrail linkwork 130,140 and of buffer gear
Reel mechanism 150.Doorframe 110 is fixedly installed on body, and gangway ladder door 120 is installed on doorframe 110, and can be relative to doorframe
110 lower rotation, to turn on or off doorframe 110.Specifically, gangway ladder door 120 can be turned-out along the bottom of doorframe 110
Turn, to open doorframe 110；Gangway ladder door 120 can also be flipped up reset along the bottom of doorframe 110, to close doorframe 110.It helps
Hand linkwork 130 is hinged with doorframe 110 and gangway ladder door 120 respectively, to carry out when switching gangway ladder door 120 to gangway ladder door 120
Limit, so that gangway ladder door 120 is merely able to rotate along preset direction, and the energy when gangway ladder door 120 is opened of handrail linkwork 130
The effect for enough serving as handrail, is assisted in convenient for occupant, improves security performance.Buffer gear 140 is installed on doorframe 110, and and the side of a ship
Terraced door 120 connects, and buffer gear 140 can provide pulling force to gangway ladder door 120 when turning on or off gangway ladder door 120, with drop
Operating force when velocity of rotation and mitigation gangway ladder door 120 when low gangway ladder door 120 is opened are closed.Mechanism 150 is reeled to be installed on
It on doorframe 110, and is connect with gangway ladder door 120, gangway ladder door 120 can be pulled by reeling mechanism 150, so that gangway ladder door 120 is closed.
It is worth noting that, gangway ladder door 120 is pushed first, so that 120 phase of gangway ladder door when needing to open gangway ladder door 120
For doorframe 110 lower rotation to predeterminated position, subsequent gangway ladder door 120 flips outward under gravity, open doorframe
110, in the process, buffer gear 140 applies the pulling force opposite with rotation direction to gangway ladder door 120, reduces gangway ladder door 120
Velocity of rotation guarantees that gangway ladder door 120 is slowly opened until supporting with ground, to reduce impact force, extension gangway ladder door 120 makes
Use the service life.
When needing to close gangway ladder door 120, manual operation reels mechanism 150, so that gangway ladder door 120 is relative to doorframe 110
Bottom revolution until close doorframe 110, in the process, buffer gear 140 to gangway ladder door 120 apply it is identical as gyratory directions
Pulling force, the operating force of operator can either be mitigated, can also guarantee that mechanism 150 is unexpected to slip out of the hand even if reeling, and will not make
The case where opening rapidly at gangway ladder door 120 reduces human cost, improves security performance.
It should be noted that the quantity of handrail linkwork 130 is two, two handrail linkworks in the present embodiment
130 are relatively arranged on the two sides of gangway ladder door 120, and hinged with the two sides of doorframe 110 respectively, in order to which occupant assists in.Buffer
The quantity of structure 140 is two, and two buffer gears 140 are relatively arranged on the two sides of gangway ladder door 120, each buffer gear 140
Position is corresponding with the position of a handrail linkwork 130, to improve buffering effect.The quantity for reeling mechanism 150 is one,
The position for reeling mechanism 150 is corresponding with the position of one of handrail linkwork 130, it is only necessary to which a people can realize gangway ladder
The rotary closure of door 120.
Incorporated by reference to referring to Fig. 2, Fig. 3 and Fig. 4, handrail linkwork 130 includes the first handrail 131, the second handrail 132, branch
