Description

Technical Field

[0001] This utility model relates to the field of supplementary lighting devices, specifically an image acquisition supplementary lighting device for internet-based teaching. Background Technology

[0002] A supplementary lighting device is used to add diffused light to the shooting location during the shooting process. In live teaching and online classes, supplementary lighting is also needed to ensure that students can see the teaching content clearly. Some existing supplementary lighting devices are inconvenient to adjust during use. An existing authorized patent for an image acquisition supplementary lighting device for teaching based on the Internet (authorization announcement number CN202020837499.2) can independently adjust the height of the supplementary light, thus solving the problem of inconvenient adjustment.

[0003] However, during the adjustment process, the stability between the base and the fill light is poor, and the entire fill light device needs to be lifted up, which is quite laborious.

[0004] Therefore, we have made improvements to this by proposing an image acquisition and supplementary lighting device based on Internet teaching. Utility Model Content

[0022] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0023] Example: Figures 1 to 4 As shown, this utility model discloses an image acquisition supplementary lighting device for internet-based teaching, comprising a base 1, a support rod 5 fixedly mounted on the top surface of the base 1, and a mounting plate 6 fixedly mounted on the top surface of the support rod 5. The base 1 supports the support rod 5, and the support rod 5 supports the mounting plate 6. A threaded rod 7 is symmetrically rotatably mounted on the front of the mounting plate 6. A connecting block 10 is threadedly connected to the threaded rod 7. A mounting bracket 11 is mounted on the connecting block 10. A rotating shaft 12 is rotatably mounted on the mounting bracket 11. A connecting seat 17 is fixedly sleeved on the rotating shaft 12. A supplementary light 14 is fixedly mounted on the connecting seat 17. An existing controller is mounted on the side of the mounting plate 6. The supplementary light 14 is electrically connected to the controller. The supplementary light 14 is existing technology, and its internal structure and working principle will not be described in detail here.

[0024] When the threaded rod 7 rotates, the connecting block 10 on it moves, causing the mounting bracket 11 and the rotating shaft 12 on the mounting bracket 11 to move. This, in turn, moves the connecting seat 17 and the supplementary light 14, allowing the height of the supplementary light 14 to be adjusted. When the angle of the supplementary light 14 needs to be adjusted, the rotating shaft 12 can be rotated to rotate the connecting seat 17, which in turn rotates the supplementary light 14. The height and angle of the two supplementary lights 14 can be adjusted separately.

[0025] The two ends of the rotating shaft 12 are respectively provided with protrusions 18, and the protrusions 18 are provided with abutting blocks 16. One end of the abutting block 16 is provided with an adjusting screw 13. By rotating the adjusting screw 13, the abutting block 16 is moved away from the protrusions 18 when the angle of the supplementary light 14 is adjusted. After the angle of the supplementary light 14 is adjusted, the abutting block 16 is pressed against the protrusions 18 for limiting.

[0026] Multiple casters 2 are evenly arranged at the bottom of the base 1, and a chassis 20 is provided in the middle of the bottom surface of the base 1. The casters 2 facilitate the movement of the supplementary lighting device, and the chassis 20 can prevent the device from moving when using it for supplementary lighting, thereby enhancing stability.

[0027] The mounting plate 6 has symmetrical mounting grooves on its front side. The threaded rod 7 is rotatably mounted in the mounting groove, and the bottom end of the threaded rod 7 rotates through the mounting groove and extends to the bottom of the mounting plate 6. The bottom end of the threaded rod 7 is fixedly mounted with a handle 15, which can be manually rotated to drive the threaded rod 7 to rotate, thereby adjusting the height of the connecting block 10.

[0028] The mounting plate 6 has symmetrically provided sliding grooves 8 on the front and on both sides of the mounting slot. A slider 9 is slidably disposed in the sliding groove 8 and is fixedly connected to the mounting bracket 11. The mounting bracket 11 slides in the sliding groove 8 through the slider 9, which can play a guiding role.

[0029] Both ends of the rotating shaft 12 are rotatably connected to the inner wall of the mounting bracket 11, and grooves 19 are provided in the middle of both ends of the rotating shaft 12. Protrusions 18 are provided in the grooves 19, and the diameter of the protrusions 18 is smaller than the diameter of the grooves 19. Adjusting screws 13 are threaded to both ends of the mounting bracket 11, and a clamping block 16 is rotatably connected to the end of the adjusting screws 13. The clamping block 16 is rotatably connected to the inner wall of the grooves 19, and a rubber anti-slip sleeve (not shown in the figure) is provided on the side of the clamping block 16 facing the protrusions 18. This is prior art and will not be described in detail here. The thickness of the protrusions 18 and the clamping block 16 is smaller than the thickness of the grooves 19.

[0030] Rotating the adjusting screw 13 can move the abutment block 16. When the abutment block 16 presses against the surface of the protrusion 18, it can prevent the rotating shaft 12 from rotating. The rubber protective sleeve can increase the friction.

[0031] An adjusting screw 3 and a connecting rod 4 are respectively provided on the base 1 and on both sides of the support rod 5. The adjusting screw 3 is threadedly connected to the base 1, and the connecting rod 4 is slidably connected to the base 1. The bottom end of the adjusting screw 3 is rotatably connected to the top surface of the chassis 20, and the connecting rod 4 is fixedly connected to the top surface of the chassis 20. Rotating the adjusting screw 3 can move the chassis 20. While the chassis 20 is moving, the connecting rod 4 will slide along the base 1. A rubber anti-slip pad (not shown in the figure) is provided on the bottom surface of the chassis 20. The rubber anti-slip pad can increase the friction. The rubber anti-slip pad is existing technology and will not be described in detail here. When it is necessary to move the device, the rubber anti-slip pad is moved to the top of the ground. When it is not necessary to move, the rubber anti-slip pad is made to adhere to the ground.

[0032] During operation, the supplementary light 14 is mounted on the mounting plate 6 and supported by the support rod 5. The bottom of the support rod 5 is provided with a base 1. The base 1, support rod 5 and mounting plate 6 are located in the same plane, which enhances the stability during use. The bottom of the base 1 is provided with casters 2 for easy movement of the device. Two supplementary lights 14 are slidably mounted on the mounting plate 6 to enhance the supplementary lighting effect during use. The positions of the two supplementary lights 14 can be adjusted separately according to the rotation of the threaded rod 7.

[0033] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
