Detailed Description

The technical solution of the present utility model is further described below, but the scope of the claimed utility model is not limited to the above.

As shown in fig. 1 to 2, the utility model provides a mine compressed air self-rescue device, which comprises a box body 1 and a switching sleeve 2, wherein a plurality of oxygen supply pipes 3 and breathing masks 4 are arranged in the box body 1, the breathing masks 4 are fixedly connected with one ends of oxygen taking pipes 5, the other ends of the oxygen taking pipes 5 are fixedly connected with switching pistons 6, one ends of the switching sleeve 2 are fixedly connected with the oxygen supply pipes 3, the switching pistons 6 are sleeved in the switching sleeve 2, and the oxygen taking pipes 5 penetrate through the other ends of the switching sleeve 2.

By adopting the technical scheme, when the respiratory mask is taken by the danger-avoidance personnel, the operation force of the danger-avoidance personnel is transmitted to the switching piston through the respiratory mask and the oxygen taking pipe, so that the switching piston slides along the length direction of the switching sleeve, the oxygen taking pipe can be pulled out by a corresponding distance, the conditions that the structures such as the respiratory mask, the air pipe and the air valve are damaged or broken due to overlarge pulling impact force caused by no gaps among all connecting members are avoided, and the normal use of the self-rescue device is ensured.
