Small structure of uncooled infrared gun aiming movement assembly

The utility model relates to the technical field of machine core assemblies, in particular to a small structure of an uncooled infrared gun aiming machine core assembly, which is used for solving theproblems of larger stress and poor stability of an infrared detector in the shooting process of the existing infrared gun aiming machine core assembly. The utility model comprises an infrared detectorand a movement housing, the infrared detector is connected with the movement housing through a cover plate cap, a PCB circuit board assembly is arranged in the movement housing, a force transmissionblock is arranged between the PCB circuit board assembly and the infrared detector, and the force transmission block contacts with the infrared detector and is connected in the movement housing. According to the utility model, the force applied to the infrared detector can be transmitted to the movement shell through the force transmission block; therefore, the force applied to the infrared detector is smaller, the infrared
