The lighting unit tends to generate a large amount of heat when working, and the heat accumulation in the equipment can easily cause the equipment to overheat and cause short circuit and combustion, which requires staff to improve their equipment. Utility Model Content

[0005] Therefore, the technical problem to be solved by the utility model is to overcome the situation in the prior art that heat accumulation in an explosion-proof lamp in the equipment easily causes the equipment to overheat and thus short-circuit and burn, thereby providing an explosion-proof lamp.

DETAILED DESCRIPTION

[0026] The technical solution of the utility model will be described clearly and completely below in conjunction with the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0027] Reference Figure 1 , Figure 2 , Figure 5 and Figure 6As shown, an explosion-proof lighting fixture comprises: a top cover 1, guide cylinders 2 are fixedly connected to both sides of the inner wall of the top cover 1, exhaust fans 3 are fixedly connected to both sides of the inner wall of the guide cylinder 2, a connecting block 4 is fixedly connected to the top of the inner wall of the guide cylinder 2, a first thread groove 20 is provided on the inner wall of the connecting block 4, a lighting assembly 5 is threadedly connected to the surface of the first thread groove 20, heat dissipation grooves 6 are provided on both sides of the top cover 1, and first baffles 7 are fixedly connected to the tops of both sides of the top cover 1;

[0028] Before using the device, the lighting assembly 5 is installed in the connecting block 4 through the first threaded groove 20, and then the lighting assembly 5 and the exhaust fan 3 are powered on. The lighting assembly 5 generates heat when lighting, and the generated hot air rises due to its lightness. The exhaust fan 3 forms a negative pressure in the guide cylinder 2 by rotating. After the negative pressure is formed in the guide cylinder 2, the hot air at the bottom that has risen is sucked into the guide cylinder 2, and then the hot air in the guide cylinder 2 is discharged from the device through the heat dissipation groove 6 through the rotation of the exhaust fan 3, thereby achieving the effect of reducing the internal heat of the device. When the device is not in use, the first baffles 7 on both sides of the top cover 1 can block falling dust to prevent dust from entering the device through the heat dissipation groove 6.

[0029] Reference Figures 1 to 4 As shown, a second thread groove 8 is provided at the bottom of the surface of the top cover 1, a mounting ring 9 is threadedly connected to the surface of the second thread groove 8, and the bottom of the mounting ring 9 overlaps the bottom of the top cover 1, a protective frame 10 is fixedly connected to the surface of the mounting ring 9, a protective tube 11 is overlapped on the inner wall of the protective frame 10, and the top of the protective tube 11 overlaps the bottom of the mounting ring 9;

[0030] After installing the lighting assembly 5, the mounting ring 9 is rotated and installed to the bottom of the top cover 1 through the second threaded groove 8. The mounting ring 9 is fixed to fix the protective frame 10 and the protective tube 11. When the equipment is hit by some larger objects, the collision object first contacts the rear protective frame 10, and the protective frame 10 blocks the collision object. Since the material of the protective frame 10 is metal, the protective frame 10 can withstand a larger force, and then the protective tube 11 is used to block some small debris, thereby protecting the lighting assembly 5.

[0031] Reference Figure 1 , Figure 2 , Figure 5 , Figure 6 and Figure 7As shown, a rotation groove 12 is provided on both sides of the top of the top cover 1, and a mounting frame 13 is rotatably connected to the inner wall of the rotation groove 12, and the two sides of the bottom of the mounting frame 13 are overlapped on the two sides of the bottom of the top cover 1, and the two sides of the mounting frame 13 are overlapped with the hand wheel 14, and a threaded rod 15 is fixedly connected to one side of the hand wheel 14, and the surface of the threaded rod 15 is threadedly connected to the bottom of the inner wall of the mounting frame 13, and a limiting ring 16 is fixedly connected to the middle of the top of the mounting frame 13, and a cable 17 is fixedly connected to the top of the top cover 1, and the surface of the cable 17 is overlapped on the inner wall of the limiting ring 16, and the bottom of the surface of the top cover 1 is fixedly connected to a second baffle 18, and the bottom of the guide cylinder 2 is fixedly connected to a connecting cylinder 19;

[0032] When it is necessary to fix the lighting of the equipment, first place the top of the mounting frame 13 to the position where it needs to be fixed, and then use bolts to fix the mounting frame 13 to the position. The fixing of the mounting frame 13 fixes the top cover 1 at the bottom. After the top cover 1 is fixed, the entire equipment is fixed. When it is necessary to adjust the lighting angle of the equipment, first rotate the top cover 1 so that the top cover 1 rotates at the bottom of the mounting frame 13 through the rotating grooves 12 on both sides, so as to adjust the angles of the two, and then rotate the hand wheel 14. The rotation of the hand wheel 14 drives the threaded rod 15 on one side to rotate, and the rotation of the threaded rod 15 moves it into the rotating groove 12, thereby squeezing the inner wall of the rotating groove 12, thereby fixing the angle of the mounting frame 13 and the top cover 1, and the second baffle 18 can prevent dust from falling on the surface of the protective tube 11 and causing pollution to the surface of the protective tube 11.

[0033] Working principle: When it is necessary to fix the lighting of the equipment, first place the top of the mounting frame 13 to the position where it needs to be fixed, and then use bolts to fix the mounting frame 13 to the position. The fixing of the mounting frame 13 fixes the top cover 1 at the bottom, and then the lighting assembly 5 is installed in the connecting block 4 through the first thread groove 20. Finally, the mounting ring 9 is rotated and installed to the bottom of the top cover 1 through the second thread groove 8. The fixing of the mounting ring 9 fixes the protective frame 10 and the protective tube 11. The exhaust fan 3 forms a negative pressure in the guide tube 2 by rotating. After the negative pressure is formed in the guide tube 2, the hot air that has risen from the bottom is sucked into the guide tube 2, and then the hot air in the guide tube 2 is discharged from the equipment through the heat dissipation groove 6 by the rotation of the exhaust fan 3. The protective frame 10 and the protective tube 11 can protect the lighting assembly 5.

[0034] Obviously, the above embodiments are merely examples for the purpose of clear explanation, and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived from them are still within the scope of protection of the utility model creation.
