Abstract
The utility model relates to a kind of fastening structures of air bag rigidity package comprising fastening assembly, floating drum cabin, floating drum covering.The fastening assembly is made of pressed seat, bolt mounting base, bolt.The floating drum cabin, floating drum cabin are composite material thin wall part, and edge is equipped with hole location, for installing fastening assembly.The utility model can guarantee that helicopter emergency gas bag is not influenced by flight aerodynamic loading, it is able to satisfy the requirement of emergency gas bag emergency quick release again simultaneously, effective solution helicopter emergency gas bag technology packet problem, fills up China in the blank in emergency gas bag rigidity technology packet field.
Description
Technical field
The utility model relates to a kind of package mechanism, especially a kind of rigidity envelope for the inflation of emergency gas bag quick release
The fastening structure of packet.
Background technique
When helicopter flight at sea, if failure needs to force-land, emergency gas bag is needed to provide buoyancy for helicopter,
And then go to escape for the time that pilot provides abundance, lifesaving success rate is provided.Emergency gas bag is mounted on helicopter exposed area,
And situations such as there can be no deformations after carrying flight aerodynamic loading for the equipment of helicopter exposed area.Meanwhile by forced landing feelings
Shape requirement, helicopter emergency gas bag should in 5s inflation.Therefore a kind of package mechanism is needed, the flight of helicopter can be met
It is pneumatic to require, and it is able to achieve the requirement of the emergency quick start of emergency gas bag
Helicopter emergency gas bag is used for helicopter ditching, strives for disembark escape time and helicopter for crew
Complete machine recycling machine meeting.Helicopter emergency gas bag is mounted on helicopter exposed area, pneumatically requires to meet the flight of helicopter, because
A kind of this air bag rigidity package mechanism, the flight that can meet helicopter pneumatically requires, and is able to achieve the emergency starting of emergency gas bag
Requirement.
Utility model content
Purpose of utility model: the purpose of the utility model is to provide it is a kind of rigidity and can quick release starting air bag rigidity
The fastening structure of package, effectively solves that emergency gas bag flight is pneumatic and the technical problem of quick release.
Technical solution
A kind of fastening structure of air bag rigidity package, including bolt, bolt mounting base and pressed seat are provided；The bolt peace
Dress seat is fixed in engine body exterior or floating drum cabin, and the bolt mounting base is connect with bolt thread, in the bolt mounting base
It is provided with pressed seat, the pressed seat is provided with through hole, and the bolt mounting base also has compression side, and the bolt through hole is set
It sets；The compression side is used to the edge of air bag rigidity package being pressed on engine body exterior or floating drum cabin；
The pressed seat is elastic material, such as rubber etc..
The pressed seat can be squeezed by the effect of air bag expansion power in air bag rigidity package, is produced at least so that compressing side
Raw elastic deformation or elastic displacement, so that the edge of air bag rigidity package disengages the constraint of pressed seat.
Further, it is formed with cavity inside the compression side of the pressed seat, which can generate elastic deformation.
Further, the bolt mounting base is fixed in engine body exterior or the mounting hole of floating drum cabin, the pressed seat
Covering bolt mounting base is simultaneously pressed on mounting hole.
Further, the through hole is threaded hole, is also cooperated with bolt thread.
Further, the air bag rigidity package is floating drum covering, and the bolt mounting base is fixed in floating drum cabin.
Technical effect
The utility model can guarantee that helicopter emergency gas bag is not influenced by flight aerodynamic loading, while be able to satisfy emergency again
Air bag is met an urgent need the requirement of quick release, and effective solution helicopter emergency gas bag technology packet problem fills up China and meeting an urgent need
The blank in air bag rigidity technology packet field.
Detailed description of the invention
Fig. 1 is the structure sectional view of the utility model；
Fig. 2 is the general illustration after the utility model installation；
Wherein: 1- bolt mounting base, 2- pressed seat, 3- bolt, 4- engine body exterior or floating drum cabin, 5- air bag rigidly seal
Packet.
Specific embodiment
