[0022] Example 1, as Figure 1-5 As shown, a mine explosion-proof tunnel light with multi-angle adjustment includes a housing 1. Wiring pipes 3 for wiring are respectively provided on both sides of the housing 1. A base plate 4 is provided at the bottom of the inner wall of the housing 1. Several light-emitting diode chips are provided on the surface of the base plate 4. An explosion-proof glass 5 is provided at the bottom of the housing 1. A protective net 6 is fixedly connected to the bottom of the housing 1 below the explosion-proof glass 5. An adjustment device 2 is provided at the top of the housing 1 to adjust the angle after the housing 1 is installed.

[0023] Reference Figure 2-6As shown in this embodiment: the adjusting device 2 includes a circular block 21 and a cylinder 23. A circular rod 22 is fixedly connected to the top of the circular block 21, and a ball block 24 is fixedly connected to the top of the circular rod 22. The bottom end of the circular block 21 is fixedly connected to the top of the housing 1 by bolts. The ball block 24 is located inside the cylinder 23. A rubber ring with an opening smaller than the diameter of the ball block 24 is provided at the bottom end of the cylinder 23. A rod with a through hole is fixedly connected to the top of the cylinder 23, and the cylinder 23 can rotate at the bottom end of the rod. A grooved rod 26 is rotatably connected to one side of the cylinder 23. A sliding rod 27 is rotatably connected to one side of the top of the circular block 21. The sliding rod 27 slides on the inner wall of the grooved rod 26. A T-shaped rod 28 is fixedly connected to one side of the sliding rod 27. The T-shaped rod 28 is located on one side of the inner wall of the grooved rod 26. The outer surface of the T-shaped rod 28 is slidably connected to a pressure block 210. A second spring 29 is provided on one side of the pressure block 210. The two ends of the second spring 29 are fixedly connected to the end of the T-shaped rod 28 away from the slide bar 27 and the side of the pressure block 210, respectively. By setting the pressure block 210, when installing the tunnel light, fasteners are used to pass through the through hole on the outer surface of the top of the cylinder 23 and connect to the inner wall of the tunnel. After the connection is completed, the top of the housing 1 is connected to the round block 21 with bolts, and the round rod 22 is fixed to the housing 1. Then, the pressure block 210 on the outer surface of the T-shaped rod 28 can be pulled to slide away from the groove bar 26 on the outer surface of the T-shaped rod 28. Then, the housing 1 is pushed to drive the round rod 22 to rotate inside the cylinder 23 through the ball block 24 to adjust the distance between the housing 1 and the cylinder 23. The tilt angle is adjusted such that when the housing 1 rotates towards the grooved rod 26, the sliding rod 27 rotates at the top of the circular block 21, and the grooved rod 26 rotates on one side of the cylinder 23. Simultaneously, the sliding rod 27 slides along the inner wall of the grooved rod 26 towards the cylinder 23. When the housing 1 rotates away from the grooved rod 26, the sliding rod 27 rotates at the top of the circular block 21, and the grooved rod 26 rotates on one side of the cylinder 23. Simultaneously, the sliding rod 27 slides outwards along the inner wall of the grooved rod 26. After the angle adjustment is complete, releasing the pressure block 210 will push it towards the grooved rod 26 via the compressed second spring 29, pressing the pressure block 210 against the outer surface of the grooved rod 26 to limit the position of the sliding rod 27 inside the grooved rod 26 and the tilt angle between the housing 1 and the cylinder 23. Subsequently, the groove rod 26 can be pushed to control the cylinder 23 to rotate at the bottom end of the rod, adjusting the orientation angle of the rod 22 and the housing 1 as a whole. Finally, the connecting wire of the tunnel light is connected to the wiring pipe 3. When the tunnel light is working, the light-emitting diode chip on the substrate 4 is energized to produce light. The explosion-proof glass 5 and protective net 6 at the bottom of the housing 1 can effectively prevent the tunnel light from being hit or exploded due to internal circuit damage. By setting the adjustment device 2, the rod 22 with ball block 24 is installed at the top of the housing 1. The tunnel light is installed by means of the rod at the top of the cylinder 23. The ball block 24 rotates inside the cylinder 23 to adjust the tilt angle between the housing 1 and the cylinder 23. The orientation angle of the tunnel light is adjusted by rotating the cylinder 23.This allows for easy adjustment of the streetlights' illumination direction after installation, enhancing their flexibility and practicality.

[0024] Reference Figure 2-6 As shown in this embodiment: a screw 212 is fixedly connected to one side of the slide rod 27, and a threaded ring 213 is threadedly connected to the outer surface of the screw 212. After pushing the housing 1 to rotate and causing the slide rod 27 to slide on the inner wall of the groove rod 26 to adjust the tilt angle between the housing 1 and the cylinder 23, the threaded ring 213 can also be rotated to move the threaded ring 213 in the direction of the outer surface of the screw 212 towards the groove rod 26, pressing one side of the threaded ring 213 against the outer surface of the groove rod 26, further restricting and fixing the position of the slide rod 27 inside the groove rod 26 and the angle between the housing 1 and the cylinder 23. A U-shaped block 211 is fixedly connected to one side of the pressure block 210. Two arc-shaped grooves are provided at one end of the U-shaped block 211. By pinching the two arc-shaped grooves at the end of the U-shaped block 211 away from the pressure block 210, it is easier to pull the U-shaped block 211 to control the pressure block 210 to move on the outer surface of the T-shaped rod 28.

[0025] Reference Figure 2-6 As shown in this embodiment: a number of rubber protrusions 214 are fixedly connected to the outer surface of the groove rod 26 near the pressure block 210. The protrusions 214 are arranged linearly on the outer surface of the groove rod 26. By setting the rubber protrusions 214, the friction between the pressure block 210 and the outer surface of the groove rod 26 when the pressure block 210 is pressed on the outer surface of the groove rod 26 can be increased, thereby improving the stability of the position of the slide rod 27 when the pressure block 210 is pressed on the surface of the groove rod 26.

[0026] Reference Figure 2-6As shown in this embodiment: The cylinder 23 is equipped with a buffer assembly 25 inside, which can buffer the vibration of the ball block 24 inside the cylinder 23 when the entire tunnel light shakes. The buffer assembly 25 includes a slider 252, a rubber block 253 fixedly connected to one side of the slider 252, and a first spring 251 provided on the side of the slider 252 away from the rubber block 253. The upper and lower ends of the first spring 251 are fixedly connected to the top of the cylinder 23 and the top of the slider 252, respectively. When the ball block 24 is inside the cylinder 23, the slider 252 is pushed by the first spring 251, causing the rubber block 253 on one side of the slider 252 to press against the outer surface of the ball block 24. When it is necessary to control the rotation of the ball block 24... The round rod 22 can be pressed towards the cylinder 23 to facilitate the rotation of the ball block 24. When small vibrations occur inside the tunnel due to the handling of items or other scenarios, the first spring 251 pushes the rubber block 253 at the bottom of the slider 252 to press against the outer surface of the ball block 24 to minimize the displacement of the ball block 24 inside the round rod 22. The bottom end of the rubber block 253 has an arc-shaped groove, and the inner wall shape of the arc-shaped groove matches the shape of the outer edge of the ball block 24. By setting the arc-shaped groove at the bottom end of the rubber block 253, the contact between the ball block 24 and the bottom end of the rubber block 253 is also tight when the round rod 22 is tilted, thus improving the effect of the buffer device.

[0027] Working principle: When installing the tunnel light, fasteners are used to connect to the inner wall of the tunnel by passing through the through hole on the outer surface of the top rod of the cylinder 23. After the connection is completed, the top of the housing 1 is connected to the round block 21 with bolts, and the round rod 22 is fixed to the housing 1. Then, the pressure block 210 on the outer surface of the T-shaped rod 28 can be pulled to slide away from the groove rod 26 on the outer surface of the T-shaped rod 28. Then, the round rod 22 is pressed to push the housing 1, which drives the round rod 22 to rotate inside the cylinder 23 through the ball block 24 to adjust the tilt angle between the housing 1 and the cylinder 23. When the housing 1 rotates towards the groove rod 26, the sliding rod 27 will rotate at the top of the round block 21, and the groove rod 26 will rotate on one side of the cylinder 23. At the same time, the sliding rod 27 will slide towards the cylinder 23 on the inner wall of the groove rod 26. When the housing 1 rotates away from the groove rod 26, the sliding rod 27 will slide towards the top of the round block 21. When the end rotates, the groove rod 26 will rotate on one side of the cylinder 23, while the slide rod 27 will slide outward on the inner wall of the groove rod 26. After the angle adjustment is completed, the pressure block 210 is released and the compressed second spring 29 will push the pressure block 210 to move towards the groove rod 26, pressing the pressure block 210 against the outer surface of the groove rod 26 to limit the position of the slide rod 27 inside the groove rod 26 and the tilt angle between the housing 1 and the cylinder 23. Then, the groove rod 26 can be pushed to control the cylinder 23 to rotate at the bottom of the rod body to adjust the orientation angle of the rod 22 and the housing 1 as a whole. Finally, the connection wire of the tunnel light is connected to the wiring pipe 3. When the tunnel light is working, the light-emitting diode chip on the substrate 4 is powered on to produce light. The explosion-proof glass 5 and the protective net 6 at the bottom of the housing 1 can effectively prevent the tunnel light from being hit or the internal circuit from being damaged and exploding.
