Problems solved by technology
[0002] At present, most of the existing domestic airborne equipment is fixed by screws, and the locking and pre-tightening force required by the airborne equipment is provided by the spring washers attached to the screws. However, when the aircraft works for a long time, the screws and the attached spring washers will fall off due to various vibrations and shocks, and fall into the interior of the aircraft, which may cause serious consequences such as short circuit or falling off of the equipment.
[0003] At present, there are also quick locks from American DFCI company in China. This kind of quick lock also forms an inseparable whole with the airborne equipment. It is easy to use, easy to operate, and can effectively prevent the screws from falling off. However, the procurement cycle of this kind of quick lock is long. , expensive; not widely accepted by the domestic market

The invention discloses a fast locking device of airborne equipment. The fast locking device comprises a fast lock, a pin (1) and a layer board base (2). The pin (1) is provided with an external thread. The fast lock is composed of a shell (3), a rotor (4) and a spring (5). The shell (3) is internally provided with a cavity (6). The head end of the rotor (4) penetrates through a second through hole (8) and passes through the cavity (6) to abut against the top of the cavity (6), and the tail part of the rotor (4) is provided with a threaded hole (9) connected with the pin (1). The spring (5) is arranged on the rotor (4) in a sleeved mode and arranged in the cavity (6). One end of the shell (3) of the fast lock penetrates through a riveting hole (10) and is connected to the riveting hole (10) in a riveting mode. The layer board base (2) is provided with two U-shaped clamping grooves (13) matched with the pin (1). The fast locking device has the advantages of being compact in structure, reasonable in price, fast in installation, easy to machine, high in reliability and large in pretightening force.
