The utility model relates to the technical field of anti-
cheating equipment, in particular to a
cheating prevention and control terminal for computer test, which comprises a
signal shielding instrument body, a circulation net is arranged on the right side of the
signal shielding instrument body, a fixing plate is mounted on the right side of the circulation net, and a cooling fan is mounted in the fixing plate. A rotating shaft is arranged on the right side of the fixed plate; and the shielding plate is installed on the outer surface of the rotating shaft, and a
magnet is installed on the left side of the shielding plate. According to the utility model, the heat dissipation fan is started, external air is absorbed and enters the
signal shielding instrument body through the heat dissipation fan, then the external air enters the interior of the signal shielding instrument body through the circulation net, the signal shielding instrument body can be subjected to overall heat dissipation, after heat dissipation is finished, the rotating shaft is rotated again, and then the
magnet and the iron block are in contact with each other; therefore, the cooling fan can be shielded, and external impurities are prevented from entering the cooling fan.
