The invention discloses an anti-loosening mechanism, a point switch air cylinder and a point switch. The anti-loosening mechanism comprises an outer anti-loosening plate, an inner anti-loosening plate, a fastening bolt, a cotter pin and a spring washer. The front end and the rear end of the outer anti-loosening plate are each provided with an inner anti-loosening plate. The top of a vertically distributed fastening bolt is arranged in the center of each inner anti-loosening plate; a cotter pin is horizontally arranged on the top of the fastening bolt and the inner anti-loosening plate in a penetrating mode. A spring washer is sleeved on the outer side of a screw rod of the fastening bolt; the fastening bolt is used for fixedly connecting the fixed part located outside with an external mounting platform on which the fixed part needs to be mounted; and the spring washer is positioned between the fastening bolt and the mounting surface of the fixed part. According to the anti-loosening device, the anti-loosening function can be conveniently and reliably achieved on fastening bolts on various devices such as a point switch, the good anti-loosening effect is achieved, the requirements of users are met, and the anti-loosening device has great practical significance.
