Description

Technical Field

[0001] The present application relates to the field of infrared detectors, and in particular to a function testing device for infrared detectors. Background Art

[0002] An infrared detector is a detector that works by detecting infrared rays emitted by the human body. In the infrared detector, the thermoelectric element detects the presence or movement of the human body and converts the output signal of the thermoelectric element into a voltage signal. The voltage signal is then subjected to waveform analysis. Thus, the detection signal is output only when the waveform generated by the human body is detected through waveform analysis.

[0003] In the prior art, when testing infrared detectors outdoors, the test device needs to be placed on a fixing device to ensure the stability of the equipment during use. The fixing devices adapted for infrared detector test devices on the market today have complex structures, making the fixing devices of the infrared detector test devices very inconvenient to carry, which causes certain troubles to the work of outdoor workers.

[0004] The above information disclosed in the background technology is only used to increase the understanding of the background technology of the present application, and therefore, it may include information that does not constitute the prior art known to ordinary technicians in the field.

On the upper surface of the fixed plate 1, rubber clamps 11 are slidably connected with the sliders 12 and the screw rods 14 on both sides thereof, and the knobs 9 are connected with the screw rods 14, so that rotating the knobs 9 drives the screw rods 14 to rotate inside the slide groove 13, and the sliders 12 are connected through the slide groove 13, and then the sliders 12 are driven to slide along the inner wall of the slide groove 13 by the rotation of the screw rods 14, and the sliders 12 are connected with the rubber clamps 11 through the rubber clamps 11, so that the screw rods 14 are rotated to drive the rubber clamps 11 to move, thereby clamping the device by driving the two rubber clamps 11 to move toward each other, thereby achieving the effect of facilitating the clamping of the device.
