Rack protection mouse hole security detector

Abstract

The invention discloses a rack protective type rat hole security check instrument which comprises a proof stick and an observation screen. The proof stick comprises a first branch stick and a second branch stick. The inner diameter of the first branch stick is identical to the outer diameter of the second branch stick. An axial sawtooth strip is arranged on the peripheral wall of the second branch stick. A strip-shaped notch matched with the sawtooth strip is formed in the first branch stick. A motor is arranged on the first branch stick. A tooth disc is fixed to a motor shaft of the motor and clamped with the sawtooth strip. An infrared camera is covered with a transparent cover. The proof stick is covered with a sawtooth strip protective cover. The rack protective type rat hole security check instrument has the advantages that device stretch and retraction are achieved through the sawtooth strip and the motor, the sawtooth strip is covered with the protective cover so that soil can be prevented from entering the sawtooth strip, and the infrared camera is waterproof due to the adoption of the transparent cover, so that when stained, a probe end is convenient to clean.

Description

technical field [0001] The invention relates to an infrared thermometer, in particular to a rack-protected rathole security detector. Background technique [0002] Infrared security detectors generally include a detection rod (1), such as figure 1 , figure 2 , one end of the detection rod (1) is provided with an infrared camera (3), the signal output of the infrared camera (3) is connected to the observation screen (2), and the observation screen (2) is provided with an A / D converter (201 ), a processor (202) and a display screen (203), the signal output terminal of the infrared camera (3) is connected to the processor (202) through the A / D converter (201), and the processor (202) processes the signal Finally, the output is displayed on the display screen (203), so that the staff can hold the detection rod (1) and extend the infrared camera (3) to places that are difficult for human eyes to reach, such as tall buildings, tree holes, rat holes, etc., but the existing The ...
