Description

Technical Field

[0001] The utility model relates to the technical field of explosion-proof lamps, in particular to an explosion-proof lamp for coal mines. Background Art

[0002] Coal mines are passages used to extract underground coal resources, one of the primary ways to obtain this vital energy source. Coal mine explosion-proof lamps are specifically designed for use in coal mines, where there is a risk of gas or coal dust explosions. Their design and manufacturing adhere to strict safety standards to prevent explosions caused by sparks from electrical equipment in potentially explosive gas or dust environments. These lamps typically utilize explosion-proof structures, capable of withstanding the pressure generated by internal explosions and preventing flames or sparks from propagating to the external environment, thereby protecting miners' lives and the integrity of mine facilities.

[0003] Currently, most coal mine explosion-proof lamps are installed at higher places in coal mines. When the tilt angle needs to be adjusted, workers are often required to use ladders or other tools to climb to the installation location of the explosion-proof lamp to make adjustments. Climbing operations are dangerous, and making adjustments at high places is troublesome and time-consuming. Utility Model Content

[0030] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0031] Figure 1 and Figure 2 All of them are schematic diagrams of the overall structure of the present invention. As shown in the figure, the coal mine explosion-proof lamp includes an explosion-proof lamp body 1, a support plate 5 and a movable rod 9. Two fixed bars 3 are symmetrically fixed to the outer wall of the explosion-proof lamp body 1 near the middle. A first hinge structure is provided on the outer wall of the explosion-proof lamp body 1 near the tail end. Two vertical bars 4 are symmetrically fixed at one end of the upper end face of the support plate 5. The top of the vertical bar 4 is hinged to the fixed bar 3. A second hinge structure is provided near the middle of the upper end face of the support plate 5. An external thread 16 is provided on the upper end of the outer wall of the movable rod 9, and a grip block 10 is installed at the bottom end of the movable rod 9. The outer wall of the grip block 10 is provided with anti-slip grooves, and the movable rod 9 is screwed through the second hinge structure, and the top of the movable rod 9 is connected to the first hinge structure through a bearing. Through the cooperation of the first hinge structure and the second hinge structure, the movable rod 9 is rotated to lift and lower, so as to realize the adjustment of the inclination angle of the explosion-proof lamp body 1.

[0032] The length of the movable rod 9 can be adjusted according to the actual installation height of the explosion-proof lamp body 1, so as to ensure that the staff standing in the coal mine can reach the grip block 10.

[0033] Among them, in the specific implementation of the present utility model, refer to Figure 1 and Figure 3 As shown, the first hinge structure includes:

[0034] Two first protruding plates 7, the two first protruding plates 7 are symmetrically fixed to the outer wall of the explosion-proof lamp body 1;

[0035] The first connecting block 13 is provided between the two first convex plates 7, and the top end of the movable rod 9 is connected to the bottom end of the first connecting block 13 through a bearing;

[0036] The shaft pin 14 is connected between the two first convex plates 7 and passes through the first connecting block 13 .

[0037] In the specific implementation of the present invention, see Figure 3 and Figure 4 As shown, the second hinge structure includes:

[0038] Two second protruding plates 8, the two second protruding plates 8 are symmetrically fixed to the upper end surface of the supporting plate 5;

[0039] The second connecting block 15 is hinged between the two second convex plates 8 , and the movable rod 9 is screwed through the second connecting block 15 .

[0040] A through hole 12 is formed on the upper end surface of the supporting plate 5 at the position of the second protruding plate 8 , and the movable rod 9 passes through the through hole 12 .

[0041] Through the above technical solution:

[0042] When the inclination angle of the explosion-proof lamp body 1 needs to be adjusted, the staff can use the grip block 10 with anti-slip grooves to rotate the movable rod 9;

[0043] When the movable rod 9 moves downward, the top of the movable rod 9 pulls the first connecting block 13 downward, so that the tail end of the explosion-proof lamp body 1 moves downward and the head end rises, and the upward angle of the explosion-proof lamp body 1 can be adjusted;

[0044] When the movable rod 9 moves upward, the top end of the movable rod 9 pushes the first connecting block 13 upward, so that the tail end of the explosion-proof lamp body 1 moves upward and the head end tilts downward, thereby adjusting the downward tilt angle of the explosion-proof lamp body 1.

[0045] As described above, whether the explosion-proof lamp body 1 is tilted upward or downward, the first connecting block 13 rotates between the two first protrusions 7, the second connecting block 15 rotates between the two second protrusions 8, and cooperates with the hinge between the fixing bar 3 and the vertical bar 4, so that the tilt angle of the explosion-proof lamp body 1 can be freely adjusted to avoid jamming.

[0046] Further, see Figure 1 and Figure 2 As shown, a mounting plate 6 is fixed to the rear end of the support plate 5 , and a mounting hole 11 is formed on the mounting plate 6 .

[0047] Specifically, the expansion bolts pass through the mounting holes 11 to fix the mounting plate 6 , thereby ensuring the stability of the installation of the explosion-proof lamp body 1 .

[0048] In addition, see Figure 1 and Figure 2 As shown, a transparent explosion-proof glass 2 is installed at the front end of the explosion-proof lamp body 1, and a sealing ring is provided at the connection between the transparent explosion-proof glass 2 and the explosion-proof lamp body 1.

[0049] Specifically, when dust from coal mining adheres to the outside of the transparent explosion-proof glass 2 and affects the lighting, the staff can directly use water to wash and wipe the outer wall of the transparent explosion-proof glass 2 to prevent the explosion-proof lamp body 1 from getting wet.
