[0047] symmetrically arranged first temperature adjusting assembly 6 and second temperature adjusting assembly 7, which have temperature displays.

[0048] In the embodiment, the synchronous driving assembly 1 can synchronously drive the first adjusting platform 2 and the second adjusting platform 3 to move towards each other or move reversely, so as to synchronously load and unload, wherein after synchronous loading, the temperature test can be realized by cooperating the first temperature adjusting assembly 6 and the second temperature adjusting assembly 7, and the multi-environment simulation assembly 5 can simulate different use environments, so as to improve the authenticity of the test and realize other performance tests of the infrared detector.

[0058] A rotating drum 62 is horizontally placed and rotatably mounted in a mounting base 61 about its central axis. An adjusting motor for driving the rotating drum's rotation is provided on one side of the mounting base 61.

[0059] Multiple circular arrays are arranged on the outer surface of the black box 63 on the rotating cylinder 62.

[0060] In practice, the rotation of the drive drum 62 can drive multiple black boxes 63 to be positioned sequentially at the bottom of the drive drum 62. Preferably, the black boxes 63 are detachably embedded in the outer surface of the drive drum, and can be replaced by disassembly.

In addition, the tilt angle of the support seat can be adjusted by extending and retracting the second telescopic cylinder 27, thereby changing the direction angle of the temperature test, improving the richness of the test and making the test closer to the real situation.
