Abstract
The invention discloses an automatic separator for night-vision goggles. The automatic separator comprises an electric detonator, a burning tube, a projection canister, a locking unit and goggle support arms. The electric detonator is mounted at one end of the burning tube; the other end of the burning tube is provided with a groove; one end of the projection canister is mounted in the burning tube; a sealed cavity is formed between the projection canister and the burning tube; the locking unit is mounted on the projection canister and is detachably fitted to the groove; the goggle support arms are mounted at the other end of the projection canister. When the electric detonator receives a start signal, the electric detonator detonates and generates high-pressure combustible gas in the sealed cavity, the high-pressure combustible gas pushes the projection canister to move out, under the thrust of the projection canister, the locking unit separates from the groove of the burning tube, and the projection canister drives the night-vision goggles to pop out to a preset position. The automatic separator has the advantages that after the start signal is received, a gunpowder device generates efficient thrust, and the night-vision goggles can be automatically separated instantly; adaptability is high.
