[0042] The following description, in conjunction with the embodiments of this utility model, includes appendices. Figures 1-6The technical solutions of the embodiments of the utility model are clearly and completely described, obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by the person skilled in the art without making creative labor belong to the range of the utility model protection.

[0043] Please refer to Figures 1-6 A mine explosion-proof and intrinsically safe sound and light signaler, including main body 1, main body 1 top is equipped with control panel 101, main body 1 inside one side is equipped with loudspeaker 105;

[0044] Main body 1 back is set up clamping groove 102, main body 1 both sides are connected through the shaft handle 2;

[0045] Through loudspeaker 105 can increase the alarm sound wave, through handle 2 can conveniently carry main body 1, through clamping groove 102 can reach the fixed limiting of handle 2.

[0046] Refer to Figure 1 And Figure 2 Clamping groove 102 inside rear inner wall is equipped with clamping plate 103, clamping plate 103 is half round setting, clamping groove 102 inside upper and lower edge is equipped with limiting plate 104 through spring, limiting plate 104 cross section is trapezoidal setting, handle 2's crossbar embeds the inside of clamping groove 102;

[0047] When not needing to use handle 2, handle 2 embeds the inside of clamping groove 102, the limiting plate 104 of this time due to spring retraction, when handle 2 embeds the inside of clamping groove 102, through clamping plate 103 the outer surface of handle 2 is clamped, and the spring of this time due to the rebounding force of itself drives limiting plate 104 reset, thereby handle 2 is blocked, avoids handle 2 to fall off.

[0048] Refer to Figure 4 Main body 1 front is located loudspeaker place top is equipped with bearing 106, bearing 106 one end is equipped with protection plate 107, protection plate 107 inboard is equipped with protection column 108, protection column 108 is rubber cylindrical, protection column 108 and main body 1 front hole are adapted;

[0049] When main body 1 is not alarming, the protection plate 107 of this time is attached to the front of main body 1, makes protection column 108 embeds to the inside of the front hole of main body 1, further avoids dust to enter the inside of main body 1 through hole, when main body 1 alarms, through loudspeaker 105 increases the sound wave of sound, and the sound wave can impact protection plate 107, makes protection plate 107 open through the factor of bearing 106, simultaneously makes protection column 108 away from the protection of hole, further carries out the alarm work.

[0050] Refer to Figure 6The inside of the main body 1 is provided with a C-shaped installation frame 3 in the hole, and the installation frame 3 comprises:

[0051] An installation groove 301 is arranged at the horizontal plate of the installation frame 3;

[0052] Limiting blocks 302 are arranged at both sides of the inside of the installation groove 301 through springs;

[0053] The limiting blocks 302 are arranged in a trapezoidal cross section;

[0054] The installation frame 3 further comprises:

[0055] An installation plate 303 is arranged in the middle of the inside of the installation groove 301;

[0056] A filter screen 304 is embedded in the inside of the installation groove 301;

[0057] The installation plate 303 is arranged in a convex cross section;

[0058] The installation frame 3 further comprises:

[0059] Limiting grooves 305 are arranged at both sides of the bottom of the filter screen 304, and the limiting grooves 305 are arranged in a trapezoidal cross section;

[0060] A butt joint plate 306 is arranged between the two limiting grooves 305 at the bottom of the filter screen 304, and the butt joint plate 306 is arranged in a concave cross section;

[0061] The filter screen 304 is embedded in the inside of the installation groove 301, at this time, the limiting blocks 302 rebound to the inside of the limiting grooves 305 due to the elastic force of the springs, and when the bottom of the filter screen 304 is embedded in the inside of the installation groove 301, the limiting blocks 302 are embedded in the inside of the butt joint plate 306 at this time, thereby positioning the filter screen 304 and avoiding the loosening of the filter screen 304;

[0062] Secondly, since the cross sections of the limiting blocks 302 and the limiting grooves 305 are both trapezoidal, when they are engaged, the filter screen 304 can be positioned, and through the convex arrangement of the installation plate 303 and the concave arrangement of the butt joint plate 306, when they are engaged, the positioning effect of the filter screen 304 can be further achieved, and the loosening of the filter screen 304 can be further avoided.

[0063] The utility model discloses an implementation principle is: first, when needing to carry main body 1, through handle 2 can carry main body 1 to lift, when not needing to carry handle 2, through embedding handle 2 in the inside of card slot 102 to fix the limiting of handle 2, when main body 1 is not alarming, the hole inside of the front of main body 1 is embedded in this protection column 108, avoid dust to enter, when main body 1 alarms. Alarm sound is enlarged through loudspeaker 105, makes the front of protection plate 107 to leave main body 1, and through filter screen 304 can effectively filter the air of outside, further avoid the entry of dust.

[0064] The above is only the preferred embodiment of the utility model and does not limit the utility model, and although the utility model is described in detail with reference to the foregoing embodiment, for those skilled in the art, the technical scheme recorded in the foregoing embodiment can still be modified, or some technical features can be replaced equivalently.
