Description

Technical Field

[0001] The utility model relates to the technical field of anti-glare lamps, in particular to a rotatable anti-glare lamp. Background Technique

[0002] In daily life and work, we often encounter the problem of glare. Especially when using lighting equipment, glare is a strong light that may stimulate the eyes, causing visual discomfort or fatigue, and may even cause eye diseases. Therefore, anti-glare lamps are used. Anti-glare lamps mainly consist of a housing, anti-glare glass, and a light source lamp. The main function of the anti-glare lamp in preventing glare lies in the anti-glare glass. Its main purpose is to reduce or eliminate the impact of glare on people's vision, thereby providing a more comfortable and healthy lighting environment. Existing anti-glare lamps generally cannot adjust the angle and direction of the light irradiation after being fixedly installed, so the lighting effect is average. There are also those with a rotating structure to adjust the lighting direction, but after adjustment, they are generally locked only by the friction at the rotating part, and the locking effect is poor. The irradiation angle is likely to change during use, and the use effect is average. Content of the Utility Model

[0003] The technical problem to be solved by the utility model is to overcome the existing defects and provide a rotatable anti-glare lamp, which can lock the rotating structure through a tooth-shaped structure and simultaneously perform self-locking by spring pressing, ensuring that the angle of the lamp housing will not change after adjustment and having a good lighting effect, effectively solving the problems in the background technique.

[0004] To achieve the above purpose, the utility model provides the following technical solution: A rotatable anti-glare lamp, including a mounting base;

[0005] Mounting base: A support frame is rotatably connected to its lower end. A retaining ring is provided at the lower end of the support frame, and the retaining ring is located below the upper side wall of the support frame. A lamp housing is rotatably connected to the lower end of the support frame. A semi-circular plate is provided on the right side surface of the lamp housing, and evenly distributed tooth grooves are formed on the outer arc surface of the semi-circular plate. A sliding seat is slidably connected inside a sliding hole in the middle of the right end of the support frame. A tooth is provided on the lower surface of the sliding seat, and the tooth is movably clamped with the vertically corresponding tooth groove. A spring piece is provided on the upper side wall in the middle of the right end of the support frame, and the lower end of the spring piece is arranged in cooperation with the sliding seat. An LED lamp board is provided on the upper side wall of the lamp housing, and an anti-glare glass plate is provided at the lower end inside the lamp housing. The input end of the LED lamp board is electrically connected to the output end of an external control switch. It can lock the rotating structure through a tooth-shaped structure and simultaneously perform self-locking by spring pressing, ensuring that the angle of the lamp housing will not change after adjustment, being convenient for rotation and locking, easy to use, and having a good lighting effect.

[0006] Further, evenly distributed tooth-shaped strips are provided on the upper surface of the retaining ring, and a tooth surface ring is provided on the upper side wall of the support frame. The tooth-shaped strips are all arranged in cooperation with the tooth surface ring, facilitating the restriction of the rotation of the support frame.

[0007] Further, a spring is movably sleeved in the middle of the mounting base. The spring is located between the support frame and the upper side wall of the mounting base, providing a downward pressure to the support frame.

[0008] Further, stoppers are provided at the left ends of the front and rear side surfaces of the sliding seat. The stoppers are located on the left side of the right side wall of the support frame, and the stoppers prevent the sliding seat from falling off.

[0009] Further, a sliding column is slidably connected to the middle of the sliding seat. An L-shaped pressing plate is provided at the left end of the sliding column. The left side wall of the L-shaped pressing plate is arranged in cooperation with the left side surface of the semi-circular plate. The upper end of the L-shaped pressing plate is slidably connected to the sliding hole in the middle of the right end of the support frame, facilitating the pressing of the semi-circular plate.

[0010] Further, the right end of the sliding column extends out of the right side surface of the sliding seat and is threadedly connected with a plum blossom handle nut, facilitating the control of the pressing of the L-shaped pressing plate.

[0011] Further, a rubber pad is provided at the lower end of the left side wall of the L-shaped pressing plate, enhancing the friction for locking.

[0012] Compared with the prior art, the beneficial effects of the present utility model are as follows: The rotatable anti-glare lamp has the following advantages:

[0013] 1. Push the support frame upward. The support frame drives the tooth surface ring to move upward and separate from the tooth-shaped strip below. Then, the support frame can be rotated. The support frame drives the lamp housing to rotate around the circular tube at the lower end of the mounting base, thereby adjusting the direction of the light irradiation. After the adjustment is completed, release the support frame. The spring pushes the support frame downward, and the support frame drives the tooth surface ring to engage with the tooth-shaped strip on the upper surface of the retaining ring, thereby restricting the rotation of the support frame. The rotation structure can be locked through the tooth-shaped structure, and at the same time, self-locking is achieved through spring pressing, ensuring that the angle of the lamp housing will not change after adjustment. The rotational locking is convenient and user-friendly.

[0014] 2. When adjusting the angle, the sliding seat can be moved upward. The sliding seat drives the teeth to separate from the tooth grooves. The sliding seat compresses the spring plate upward. Then, the lamp housing can be tilted. The circular shafts at both ends of the lamp housing rotate relative to the circular holes at the lower end of the support frame. After the angle of the lamp housing is adjusted, release the sliding seat. The sliding seat drives the teeth to move downward under the action of the spring plate and is movably clamped with the tooth grooves, thereby locking the angle of the lamp housing through the semi-circular plate. Then, tighten the plum blossom handle nut. The plum blossom handle nut drives the L-shaped pressing plate to move to the right through the sliding column. The L-shaped pressing plate drives the rubber pad to squeeze the semi-circular plate tightly, further restricting the rotation of the semi-circular plate. At the same time, the sliding seat moves to the left and is tightly squeezed with the support frame, restricting the upward movement of the sliding seat, thereby achieving a good locking effect on the semi-circular plate. After the angle of the lamp housing is adjusted, the angle of the lamp housing can be double-locked, preventing the lamp housing from rotating under gravity and changing the irradiation angle, and having a good lighting effect.

[0022] Please refer to Figures 1-5 , this embodiment provides a technical solution: a rotatable anti-glare lamp, including a mounting base 1;

[0023] Mounting base 1: A support frame 2 is rotatably connected to its lower end. The mounting base 1 is installed at a fixed position. A retaining ring 3 is provided at the lower end of the support frame 2. The lower end of the support frame 2 is rotatably connected to a lamp housing 7. By rotating the support frame 2, the support frame 2 drives the lamp housing 7 to rotate around the circular tube at the lower end of the mounting base 1. A semi-circular plate 10 is provided on the right side surface of the lamp housing 7. Uniformly distributed tooth grooves 11 are formed on the outer arc surface of the semi-circular plate 10. A sliding seat 12 is slidably connected inside the sliding hole in the middle of the right end of the support frame 2. A tooth 13 is provided on the lower surface of the sliding seat 12. The tooth 13 is movably clamped with the vertically corresponding tooth groove 11. A spring piece 14 is provided on the upper side wall in the middle of the right end of the support frame 2. The lower end of the spring piece 14 is arranged in cooperation with the sliding seat 12. By moving the sliding seat 12 upward, the sliding seat 12 drives the tooth 13 to separate from the tooth groove 11, and the sliding seat 12 compresses the spring piece 14 upward. Then the lamp housing 7 can be rotated. The circular shafts at both ends of the lamp housing 7 rotate relative to the circular holes at the lower end of the support frame 2. After the angle of the lamp housing 7 is adjusted, release the sliding seat 12. The sliding seat 12 drives the tooth 13 to move downward under the action of the spring piece 14 and is movably clamped with the tooth groove 11, thereby locking the angle of the lamp housing 7 through the semi-circular plate 10. An LED lamp board 8 is provided on the upper side wall of the lamp housing 7. An anti-glare glass plate 9 is provided at the lower end inside the lamp housing 7. The input end of the LED lamp board 8 is electrically connected to the output end of an external control switch. The LED lamp board 8 is energized to emit light, and the light illuminates a specified position through the anti-glare glass plate 9. The surface of the anti-glare glass plate 9 has a microscopic concave-convex structure, which can cause the light to form diffuse reflection on the surface of the anti-glare glass plate 9 instead of specular reflection, thereby reducing the intensity of the reflected light and reducing the generation of glare. The retaining ring 3 is located below the upper side wall of the support frame 2. Uniformly distributed tooth-shaped strips 6 are provided on the upper surface of the retaining ring 3. A tooth surface ring 4 is provided on the upper side wall of the support frame 2. The tooth-shaped strips 6 are all arranged in cooperation with the tooth surface ring 4. By pushing the support frame 2 upward, the support frame 2 drives the tooth surface ring 4 to move upward and separate from the tooth-shaped strips 6 below. A spring 5 is movably sleeved in the middle of the mounting base 1. The spring 5 is located between the support frame 2 and the upper side wall of the mounting base 1. Release the support frame 2, and the spring 5 pushes the support frame 2 downward. The support frame 2 drives the tooth surface ring 4 to engage with the tooth-shaped strips 6 on the upper surface of the retaining ring 3, thereby restricting the rotation of the support frame 2. Blocks 19 are provided at the left ends of the front and rear side surfaces of the sliding seat 12. The blocks 19 are located on the left side of the right side wall of the support frame 2. The blocks 19 prevent the sliding seat 12 from falling off. A sliding column 15 is slidably connected to the middle of the sliding seat 12. An L-shaped pressing plate 16 is provided at the left end of the sliding column 15. The left side wall of the L-shaped pressing plate 16 is arranged in cooperation with the left side surface of the semi-circular plate 10. The upper end of the L-shaped pressing plate 16 is slidably connected to the sliding hole in the middle of the right end of the support frame 2. The right end of the sliding column 15 extends out of the right side surface of the sliding seat 12 and is threadedly connected with a plum blossom handle nut 17. A rubber pad 18 is provided at the lower end of the left side wall of the L-shaped pressing plate 16. By tightening the plum blossom handle nut 17, the plum blossom handle nut 17 drives the L-shaped pressing plate 16 to move to the right through the sliding column 15. The L-shaped pressing plate 16 drives the rubber pad 18 to squeeze the semi-circular plate 10 tightly, further restricting the rotation of the semi-circular plate 10. At the same time, the sliding seat 12 is squeezed tightly against the support frame 2 to the left, restricting the upward movement of the sliding seat 12.Furthermore, it has a good locking effect on the semi-circular plate 10.

[0024] The working principle of a rotatable anti-glare lamp provided by the present utility model is as follows: When in use, the mounting base 1 is installed at a fixed position, and then the direction and angle of the light irradiation can be adjusted according to the usage requirements. When adjusting the angle, the slide seat 12 can be moved upward. The slide seat 12 drives the tooth 13 to separate from the tooth groove 11. The slide seat 12 compresses the spring piece 14 upward, and then the lamp housing 7 can be rotated. The round shafts at both ends of the lamp housing 7 rotate relative to the round holes at the lower end of the support frame 2. After the angle of the lamp housing 7 is adjusted, the slide seat 12 is released. Under the action of the spring piece 14, the slide seat 12 drives the tooth 13 to move downward and engage with the tooth groove 11 movably, thereby locking the angle of the lamp housing 7 through the semi-circular plate 10. Then, the plum blossom handle nut 17 is tightened. The plum blossom handle nut 17 drives the L pressing plate 16 to move rightward through the sliding column 15. The L pressing plate 16 drives the rubber pad 18 to squeeze the semi-circular plate 10 tightly, further restricting the rotation of the semi-circular plate 10. At the same time, the slide seat 12 is squeezed tightly against the support frame 2 to the left, restricting the upward movement of the slide seat 12, and further having a good locking effect on the semi-circular plate 10. After the angle is adjusted, the support frame 2 can be pushed upward. The support frame 2 drives the tooth surface ring 4 to move upward and separate from the tooth-shaped strip 6 below. Then, the support frame 2 can be rotated. The support frame 2 drives the lamp housing 7 to rotate around the round tube at the lower end of the mounting base 1, thereby adjusting the direction of the light irradiation. After the adjustment is completed, the support frame 2 is released. The spring 5 pushes the support frame 2 downward. The support frame 2 drives the tooth surface ring 4 to engage with the tooth-shaped strip 6 on the upper surface of the retaining ring 3, thereby restricting the rotation of the support frame 2 and ensuring good self-locking after the angle of the lamp housing 7 is adjusted. When in use, an external control switch is adjusted, and the LED lamp board 8 is energized to emit light. The light illuminates a specified position through the anti-glare glass plate 9. The surface of the anti-glare glass plate 9 has a microscopic concave-convex structure, which can cause the light to form diffuse reflection on the surface of the anti-glare glass plate 9 instead of specular reflection, thereby reducing the intensity of the reflected light and reducing the generation of glare.
