Description
Technical field
The utility model relates to that a kind of aircraft is conventional safeguards lid, particularly relates to a kind of fast aeration lid.
Background technology
The small-sized lid of system maintenance on the various aircraft in the past manufactured and designed at home, periphery adopts a circle plate nut to fix lid usually, its Problems existing be aircraft delivery use after daily attention in dismantle more inconvenient, all plate nuts must be pulled down when adopting this lid type of attachment to dismantle, safeguard in using and often dismantle, need the cost plenty of time and easily cause plate nut to lose efficacy and bolt loss.
Therefore, need to provide a kind of new technical scheme to solve the problems referred to above.
Utility model content
The utility model technical issues that need to address are to provide a kind of fast aeration lid.
For solving technical matters of the present utility model, the technical solution adopted in the utility model is:
A kind of fast aeration lid, this lid comprises box, lid cover plate, poker, hinge, left side pad, right pads and quick-detachable lock, box and lid cover plate composition box-like device, box-like device one end is connected and fixed by fastener by hinge and lid cover plate, hinge rotates around poker, left, right pads is positioned at poker both sides, left, right pads is fixed on lid cover plate, the box-like device other end connects lid cover plate combination by quick-detachable lock and forms, described box is connected to fix aboard by fastener with aircraft skin, described box center has through hole, this through hole connects mouth for installing inflation, described inflation connects mouth and is connected with gas conduit, fastener assembly is adopted inflation to be connect mouth is fixed on box bottom by one piece of connecting panel.
Further, described fastener is rivet.
Further, described fastener assembly comprises screw and plate nut.
Different from the lid that other most of aircrafts domestic enclose plate nut fixing by periphery one, the box-like device of this novel quick-release lid is sheet metal part, bottom box according to pipeline system need have through hole, can pass through and fixed system pipeline, one end of box has waist through hole, open for being arranged on cover plate place quick-detachable lock, the use of quick-release dead bolt time closed, box body is fixed respectively by several rivet interlacement laminating by four, the inside crimp of box-like device.
The beneficial effects of the utility model: the box-like device of this novel quick-release lid both can realize connecing the fixing of mouth to system pipeline inflation, can realize again the isolation with system greasy dirt and aircraft exterior dust etc. in body.
