Description
Technical field
This utility model relates to a kind of without fixed hinge formula quick-release lid, belongs to airplane hatch cover technical field.
Background technology
The system lid on various aircraft the most in the past manufactured and designed, periphery generally uses a circle plate nut solid
Determining lid, it there is problems of dismantling in the regular maintenance after aircraft delivery uses more inconvenient, uses this lid even
All of plate nut must be pulled down when connecing form dismounting, safeguard that in using, often dismounting needs take a significant amount of time and hold
Easily cause plate nut lost efficacy and lost, and use this kind can largely avoid these to ask without fixed hinge formula quick-release lid
Topic.
Utility model content
The purpose of this utility model is to provide a kind of without fixed hinge formula quick-release lid.
The utility model is achieved like this.A kind of without fixed hinge formula quick-release lid, including frame suitable for reading, cover plate, under
Mouth frame, cloud shape are locked and hinge, and frame suitable for reading, end opening frame are connected and fixed on aircraft by rivet and airframe, and cover plate is positioned at
Between frame suitable for reading and end opening frame, hinge is installed in one end of cover plate, by two hinges, cover plate is fixed on airframe, cover plate
The other end upper lock body of two cloud shapes lock is installed, the down lock body of two cloud shape locks is attached separately on frame suitable for reading, end opening frame.
Different from the lid that other most of aircrafts domestic are enclosed plate nut fixing by periphery one, this formula without fixed hinge
Quick-release lid is while being to be connected with cover plate by leaf of hinge, poker and several one side countersunk rivets, and one end is to be locked by 2 cloud shapes
Connect fixing.When dismounting uses, only need to rotate 45 ° counterclockwise opens Yun Xingsuo, and the cover plate of lid just can be opened, without
Tear several plate nut open whole lid to be disassembled, the maintainability of aircraft can be improved.
Accompanying drawing explanation
Fig. 1 is schematic diagram of the present utility model.
1. frames suitable for reading, 2. cover plate, 3. end opening frame, 4. cloud shape lock, 5. hinge in figure.
Detailed description of the invention
As it is shown in figure 1, it is a kind of without fixed hinge formula quick-release lid, including frame 1 suitable for reading, cover plate 2, end opening frame 3, cloud shape lock 4
With hinge 5, frame 1 suitable for reading, end opening frame 3 be connected and fixed on aircraft by rivet and airframe, and cover plate 2 is positioned at frame 1 suitable for reading
With between end opening frame 3, hinge 5 is installed in one end of cover plate 2, is fixed on airframe by 5 cover plates 2 of two hinges, cover plate 2
The other end upper lock body of two cloud shapes lock 4 is installed, the down lock body of two cloud shape locks 4 is attached separately on frame 1 suitable for reading, end opening frame 3.
Cover plate 2 determines quantity and the length of hinge according to lid size and requirement of strength.The regular maintenance of aircraft afterwards
In, only need to rotate 45 ° of cloud shape locks counterclockwise and can open lid, the system of aircraft is safeguarded.Then by cover plate 2 to hinge
5 direction, sides are opened, and whole lid i.e. can be opened, and are safeguarded system by the through hole between upper and lower mouth frame；Safeguarding
After end, only need to be by 2-in-1 for cover plate, the Guan Bi locked by cloud shape realizes the Guan Bi of whole lid.
