[0021] The utility model is further described in detail below in conjunction with the accompanying drawings and embodiments.

[0022] Reference Figures 1 to 6 This embodiment includes a mounting mechanism 1, a positioning mechanism 2 and a gas alarm body 3. The gas alarm body 3 is mounted on the side of the positioning mechanism 2, and the positioning mechanism 2 is mounted on the mounting mechanism 1.

[0023] The mounting mechanism 1 includes a mounting frame assembly 11 and an alarm light 12 fixedly connected to the lower end of the mounting frame assembly 11; the positioning mechanism 2 includes a slide assembly 21 and a positioning assembly 22 and a driving assembly 23 installed on the slide assembly 21, the slide assembly 21 is limited and slidably embedded in the mounting frame assembly 11, and the positioning assembly 22 fixes and limits the slide assembly 21; the gas alarm body 3 is fixedly mounted on the slide assembly 21.

[0024] The mounting frame assembly 11 includes a connecting rod 111 , the upper end of which is fixedly connected to a mounting frame body 112 , and the outer periphery of the connecting rod 111 has a plurality of linearly evenly distributed positioning slots 113 .

[0025] Specifically, the gas alarm body 3 is fixed on the slide assembly 21 after being penetrated by a screw, and the mounting frame assembly 11 is fixed on the predetermined top of the mine, and the gas alarm body 3, the alarm light 12 and the external host are connected to each other. When working, the gas alarm body 3 is responsible for detecting the concentration of specific gases in the air. When it is detected that the concentration of specific gases in the mine is too high, it is fed back to the host and controls the alarm light 12 to work. The alarm light 12 can remind the staff to evacuate quickly; when it is necessary to move the height of the gas alarm body 3, the positioning assembly 22 can be moved and separated from the mounting frame assembly 11 by pressing the drive assembly 23. At this time, the staff can conveniently adjust the position of the slide assembly 21 on the mounting frame assembly 11, so that it can adjust its own height according to the specific gas density. After releasing the drive assembly 23, the positioning assembly 22 is reset and embedded in the mounting frame assembly 11 again to fix the slide assembly 21.

[0026] The slide assembly 21 includes a slide body 211, a mounting plate 212, an L-shaped bracket 213, an axle rod 214 and a first handle 215. The mounting plate 212 has a large circular hole for the mounting frame assembly 11 to pass through. The mounting plate 212 is fixed to one side of the slide body 211. The L-shaped bracket 213 and the axle rod 214 fix the slide body 211 on one side relative to the mounting plate 212. The first handle 215 is located below the slide body 211. The L-shaped bracket 213 and the slide body 211 are penetrated by small circular holes through which the positioning assembly 22 passes. The small circular hole on the slide body 211 is connected to the large circular hole, and circular protrusions are provided on both sides of the axle rod 214.

[0027] The positioning assembly 22 includes a positioning rod 221, a spring 222 and a limiting ring 223. The limiting ring 223 is fixed on the outer circumference of the positioning rod 221. The spring 222 is sleeved on the outer circumference of the positioning rod 221. The positioning rod 221 is placed in the holes of the L-shaped bracket 213 and the slide body 211, and the spring 222 abuts against the L-shaped bracket 213 and the limiting ring 223 at the same time.

[0028] The driving assembly 23 includes a push plate 231 and a second handle 232 fixed below the push plate 231. One side of the push plate 231 also has a hole for the positioning rod 221 to pass through, and the other side has a through groove that is mutually engaged with the shaft rod 214. The shaft rod 214 has circular protrusions on both sides, and the corresponding side surfaces of the through groove have holes, so that the push plate 231 can rotate when it is engaged on the shaft rod 214.

[0029] Therefore, there are positioning components 22 and driving components 23 between the L-shaped bracket and the carriage body 211 bracket. Specifically, the hole on the push plate 231 is aligned with the small round hole of the L-shaped bracket and the carriage body 211 bracket. The positioning rod 221 is inserted into the hole under the condition of compressing the spring 222 to complete the engagement. At this time, the push plate 231 is rotated to push the limit ring 223 to move, thereby compressing the spring 222, so that the positioning rod 221 moves in a direction away from the mounting plate 212. Specifically, the connecting rod 111 is fixedly installed on the top of the mine through the mounting frame body 112, and the positioning rod 221 can be embedded in the positioning slot 113.

[0030] The implementation principle of a mine safety warning device in an embodiment of the utility model is:

[0031] Hold the first handle 215 and press the second handle 232, the second handle 232 will drive the push plate 231 to rotate around the shaft 214, the rotation of the push plate 231 will cause the limit ring 223 to drive the positioning rod 221 to disengage from the positioning slot 113, at this time the staff can easily move the slide body 211 on the mounting frame assembly 11, the limit ring 223 will also cause the spring 222 to be compressed when it moves, when the second handle 232 is released, the spring 222 will reset and cause the positioning rod 221 to embed into the designated positioning slot 113, thereby positioning the slide body 211.
