Specific embodiments

[0026] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model with reference to the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, rather than all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present utility model.

[0027] As Figures 1 to 4 shown, it relates to an explosion-proof signal lamp, including an explosion-proof signal lamp body 1. One end of the explosion-proof signal lamp body 1 is fixedly connected with a mounting base 3. The explosion-proof signal lamp body 1 and the mounting base 3 are fixed by bolts, which is convenient for disassembly and assembly. A guiding component is arranged above the mounting base 3. The guiding component includes a fixed seat 2, and the fixed seat 2 is located above the mounting base 3. Two guiding wheels 8 are rotatably connected to the inner walls of both sides of the fixed seat 2. Mounting plates are fixedly connected to both sides of the fixed seat 2, which is convenient for fixing the fixed seat 2 on an external building.

[0028] Below the mounting base 3 is provided with a housing 7. On one side inner wall of the housing 7, a winding wheel 13 and an unwinding wheel 12 are symmetrically and rotatably connected. The outer surfaces of the winding wheel 13 and the unwinding wheel 12 are jointly fixed with a winding auxiliary rope 5 around them. And the auxiliary rope 5 passes through the housing 7 and is connected with the guiding assembly. And the guiding wheel 8 abuts against the auxiliary rope 5. And the mounting base 3 is fixedly sleeved on the outer surface of the auxiliary rope 5. On the top of the housing 7, two through holes penetrating to the inside are symmetrically opened. And the through holes match the auxiliary rope 5. On one side of the top of the mounting base 3, a through hole penetrating to the bottom is opened. And the through hole matches the auxiliary rope 5. The positional relationship of the through hole is shown in Figure 2 to avoid affecting the movement of the mounting base 3.

[0029] A large belt pulley 16 is jointly rotatably connected between each of the winding wheel 13 and the unwinding wheel 12 and the housing 7. A regulating belt pulley is installed at the top end of the housing 7. A belt body 15 is jointly sleeved between the two large belt pulleys 16 and the regulating belt pulley. The regulating belt pulley includes a regulating bolt 9. And the regulating bolt 9 passes through the housing 7 and is rotatably connected therewith. An adjusting seat 11 is threadedly sleeved on the outer surface of the regulating bolt 9. On one side of the outer surface of the adjusting seat 11, a small belt pulley 14 is rotatably connected. And the small belt pulley 14 abuts against the belt body 15. On one side of the outer surface of the adjusting seat 11, a limiting block 10 is slidably connected. And the limiting block 10 is fixedly connected with the housing 7. By screwing the regulating bolt 9, the regulating bolt 9 drives the adjusting seat 11 and the small belt pulley 14 to move downward, making the belt body 15 loose. At this time, the two large belt pulleys 16 cannot rotate synchronously through the belt body 15.

[0030] On one side of the outer surface of the housing 7 is provided with a hand wheel 6. And the mounting shaft of the hand wheel 6 passes through the housing 7 and is fixedly connected with the adjacent large belt pulley 16. The setting of the hand wheel 6 facilitates driving the large belt pulley 16 connected thereto to rotate.

[0031] One end of the lamp holder of the explosion-proof signal lamp body 1 is threadedly connected with a lamp cover 4. Unscrewing the lamp cover 4 can facilitate the replacement of the signal lamp installed on the lamp holder of the explosion-proof signal lamp body 1.

[0032] Working principle: When it is necessary to adjust the use length of the auxiliary rope 5, turn the adjusting bolt 9. The adjusting bolt 9 drives the movable seat 11 and the small pulley 14 to move downward, making the belt body 15 loose. Then, drive the large pulley 16 connected thereto to rotate by the handwheel 6, thereby driving the winding wheel 13 to rotate counterclockwise to release the auxiliary rope 5 until the length reaches the required value. Then, reverse the adjusting bolt 9, and the adjusting bolt 9 drives the movable seat 11 and the small pulley 14 to move upward until the belt body 15 is tightened; when it is necessary to lower the explosion-proof signal lamp body 1, drive the handwheel 6 to rotate forward, and then drive the winding wheel 13 and the unwinding wheel 12 to rotate through the large pulley 16, the small pulley 14 and the belt body 15. The winding wheel 13 releases the auxiliary rope 5, and the unwinding wheel 12 winds up the auxiliary rope 5, thereby driving the mounting seat 3 to move downward. The mounting seat 3 drives the explosion-proof signal lamp body 1 to move downward until the height reaches the required value.
