The utility model aims at providing a can solve the fixed problem of installation and easy dismounting's of fire-extinguishing bottle under narrow and small space stationary vane aircraft fire-extinguishing bottle installation device.
In order to achieve the above purpose, the utility model adopts the following technical scheme: a fixed wing aircraft fire-extinguishing bottle mounting device comprises a fixing piece, a belt-shaped piece and a quick-release device; the fixing piece is used for installing and fixing the belt-shaped piece on the airplane frame; the belt-shaped piece is used for containing a fire extinguishing bottle; the quick release device is arranged at the free end of the belt and used for opening or tightening the belt.
Preferably, the fixing piece is a bracket and a rivet; the support is fixed on the airplane frame through a rivet.
Preferably, the belt-shaped members are a plurality of belt straps connected through triangular rings and are connected and fixed with the support through rivets.
Preferably, the quick-release device comprises a connecting piece, a quick-release nut and a screw rod; the connecting piece is fixed at the free end part of the belt-shaped piece and is provided with a through hole for the screw rod to pass through, and the quick-release nut is matched with the screw rod and is screwed at the end part of the screw rod.
Preferably, the quick-release nut is a butterfly nut.
Preferably, the free ends are two pairs and are adjacently arranged.
The working principle is as follows: adopt the area of band to take the lock form of unloading soon to fix circular fire-extinguishing bottle on the aircraft frame outside the fire district reliable and stable, when the fire-extinguishing bottle was dismantled, only need to twist off the quick-release nut on the band, the fire-extinguishing bottle just can down be dismantled, when the fire-extinguishing bottle was installed, only need open the band, the fire-extinguishing bottle just can be installed toward the aircraft, can solve the fixed problem of installation of fire-extinguishing bottle under the narrow and small space and satisfy convenient quick installation and dismouting requirement, this band form has light in weight's advantage simultaneously.
Compared with the prior art, the utility model has the advantages of as follows:
1. the problem of the installation of fire-extinguishing bottle under the narrow and small space is fixed and satisfy convenient quick installation and dismouting requirement, this band form has light in weight's advantage simultaneously.
2. Manpower and time are saved for maintenance of the aircraft.
Drawings
FIG. 1 is a schematic structural diagram of an embodiment of the present invention;
in the figure, 1, a bracket; 2. wrapping belts; 3. a triangular ring; 4. quickly disassembling the nut; 5. a screw.
Detailed Description
The present invention will be described in detail with reference to the accompanying drawing 1: as shown in fig. 1, the fixed-wing aircraft fire-extinguishing bottle mounting device comprises a bracket 1, a belt 2, a triangular ring 3, a quick-release nut 4 and a screw rod 5; the support 1 is fixed on the airplane frame through rivets; the belt 2 is provided with a plurality of belts, which are connected and fixed through the triangular rings 3 to form a circle for containing a round fire-extinguishing bottle, the free ends of the belt 2 are connected and fixed through a quick-release device so as to be convenient for the installation and the disassembly of the fire-extinguishing bottle, and the round structure formed by the belt 2 is fixed on the bracket 1 through rivets; the quick-release device is used for opening or tightening the wrapping tape 2 and comprises a connecting piece, a quick-release nut 4 and a screw rod 5; the connecting piece is fixed at the free end of the belting 2 and is provided with a through hole for the screw rod 5 to pass through, the through hole is arranged oppositely, and the quick-release nut 4 is matched with the screw rod 5 and is screwed at the end part of the screw rod.
In order to facilitate the installation and the disassembly of the fire extinguishing bottle, the free ends of the wrapping belts 2 are arranged into two pairs, the two pairs are arranged adjacently and are close to the lower part, and the opening is larger, so that the fire extinguishing bottle is more favorable for the installation from bottom to top and the downward disassembly.
The installation process of the fire extinguishing bottle of the certain tandem double-seat fixed wing aircraft is as follows:
