An alarm device for an escape hatch is composed of an emergency handle (1), a lock shaft (3) and a support assembly (5). A spring bolt (2) is fixedly installed in the middle of the lock shaft (3). The emergency handle (1) is fixedly connected to the top end of the lock shaft (3). The lock shaft (3) is movably connected to the support assembly (5). A lock groove (6) is formed in the support assembly (5). The alarm device is characterized in that a microswitch (4) is fixedly installed on the support assembly (5), installed on one side of the lock shaft (3) and located below the spring bolt (2), and the emergency handle (1) is pulled to drive the lock shaft (3) to rotate so that the spring bolt (2) can enter the lock groove (6) and press down the microswitch (4). The alarm device is simple in structure and convenient and rapid to install, an automobile driver can quite visually recognize whether the escape hatch is opened or closed through a signal lamp, and potential safety hazards during driving are eliminated.
