FIELD: transport.
SUBSTANCE: proposed lock comprises case accommodating bearing and support levers fitted therein on axles and support lever lock mechanism. Support lever lock mechanism consists of articulated system of levers to interact with bearing lever. Bearing level bore receiving axle and mating axle part features oval shape to allow translation of bearing lever relative to rotary axle under weight gravity. Said rotary axle is secured in casing while oval section of rotary axle has cylindrical cavity arranged perpendicular thereto to accommodate spring-loaded cup moving therein to interact with bearing lever. Support lever lock mechanism incorporates micro switch and electromagnetic trigger, interconnected and connected to onboard circuit, to interact with bearing and support levers, respectively. Additionally casing incorporates additional cargo availability signaling micro switch interacting with one of support lever lock mechanisms and electrically connected with onboard circuit.
EFFECT: higher safety of helicopter flight and reliable operation of lock.
