[0031] Working principle and use process of the utility model: In the actual application process of the explosion-proof device of the coal mine underground detection robot, it is first necessary to adjust the interval width between the first explosion-proof middle shell 1 and the second explosion-proof middle shell 2 according to the chassis width of the detection robot used, so that the interval width between the first explosion-proof middle shell 1 and the second explosion-proof middle shell 2 can meet the use requirements of the chassis width of different types of detection robots;

[0032] In the specific adjustment process, the connecting threaded rod 11 is rotated by the knob 12 to cooperate with the guide rod 10, so that the second sliding connecting plate 7 moves relative to the first sliding connecting plate 6 under the action of the thread drive, and in the process of sliding between the first sliding connecting plate 6 and the second sliding connecting plate 7, the fitting connection between the guide block 9 and the guide groove 8 is used to ensure the sliding accuracy of the second sliding connecting plate 7 and avoid the phenomenon of deviation.
