[0003] After searching, the patent number is CN214670002U, and the name is a utility model of an adjustable fill light for online educational videos, including a base. Through research and analysis, it is found that although it has the advantage of multi-angle adjustment, it still has the following disadvantages to a certain extent.

[0004] For example, when adjusting the height, it is only adjusted through a simple telescopic rod, and the two rods cannot be positioned and fixed, resulting in instability after adjustment. In addition, it does not have the function of time reminder, which makes it difficult for teachers to better control the progress of the class. When the class time is up, they do not know, so that the class is delayed and affects the arrangement of other courses. In order to solve the above technical problems, we have designed an adjustable fill light for online educational videos. Utility Model Content

[0014] The utility model pulls the pulling plate to move the short rod and the resisting plate, so that the resisting plate is separated from the circular plate and the spring 2 for compression, and the slider is moved on the circular plate to move the target plate to the scale of the corresponding value. During online education classes, the operation of the servo motor is controlled to perform timing. The servo motor drives the rotation of the round block and the rubber ring, and then drives the rotation of the rubber ring, the circular plate and the pointer, thereby having the advantage of being able to provide time prompts to teachers, so that teachers can better control the progress of the class. As the pointer continues to rotate and contacts the target board, it indicates that the class time is over, avoiding class delays that affect the arrangement of other courses.

[0022] See also Figure 2 and Figure 3 The adjusting mechanism 2 includes a vertical cylinder 21, the bottom end of the vertical cylinder 21 is fixedly connected to the top of the battery base 1, the vertical rod 22 is slidably inserted into the inner cavity of the vertical cylinder 21, and a groove 23 is provided on the surface of the bottom end of the vertical rod 22. The inner wall of the groove 23 is fixedly connected with a spring 1 24. By setting the spring 1 24, the block 25 is better inserted into the card hole under the action of its elastic force, thereby limiting the position between the vertical cylinder 21 and the vertical rod 22. The left end of the spring 1 24 is fixedly connected with the card block 25, and the right side of the card block 25 is fixedly connected with a connecting rope 26. By setting the connecting rope 26, the card block 25 can be moved under the action of the pull ring 27, so that the card block 25 is separated from the card hole. The end of the connecting rope 26 away from the card block 25 passes through the top of the vertical rod 22 and is fixedly connected with the pull ring 27.

[0023] See also Figure 3 A guide block 28 is fixedly connected to the bottom of the right side of the vertical rod 22, and a guide groove 29 adapted to the guide block 28 is opened on the right side of the inner cavity of the vertical cylinder 21. By setting the guide block 28 and the guide groove 29, the vertical rod 22 is limited and guided when it moves up and down, so that the block 25 on the adjusted vertical rod 22 can be more accurately inserted into the block hole on the vertical cylinder 21 to prevent the vertical rod 22 from rotating when moving. A block hole adapted to the block 25 is opened on the left side of the vertical cylinder 21.

[0024] See also Figure 1 and Figure 4The driving mechanism 6 includes a rubber ring 63, and the circular ring 61 is rotatably sleeved on the surface of the circular plate 4. A ball 62 is provided between the inner surface of the circular ring 61 and the outer surface of the circular plate 4. By providing the ball 62, the circular plate 4 and the circular ring 61 are limited so that the circular ring 61 can rotate on the surface of the circular plate 4. The rubber ring 63 is fixedly sleeved on the surface of the circular ring 61. The bottom of the circular plate 4 is fixedly connected to a short plate 64, and the left side of the short plate 64 is fixedly connected to a servo motor 65. The rotating shaft of the servo motor 65 passes through the short plate 64 and is fixedly connected to a round block 66. The surface of the round block 66 is fixedly sleeved with a rubber ring 67. By providing the rubber ring 63 and the rubber ring 67, the circular ring 61 can rotate stably under the drive of the servo motor 65 to avoid slipping during rotation. The surface of the rubber ring 67 is in contact with the surface of the rubber ring 63.

[0025] See also Figure 4 and Figure 5 The target positioning mechanism 9 includes a slider 91. By setting the slider 91, a mounting position is provided for the target plate 96 and the short rod 92. At the same time, it can rotate on the right side of the circular plate 4. The slider 91 slides and is clamped on the surface of the circular plate 4. The right side of the slider 91 slides through a short rod 92. The left end of the short rod 92 is fixedly connected to a plate 93. The surface movable sleeve of the left end of the short rod 92 is provided with a spring 2 94. By setting the spring 2 94, the plate 93 is brought into contact with the surface of the circular plate 4 under the action of its elastic force, thereby positioning the slider 91 and the target plate 96. The two ends of the spring 2 94 are respectively fixedly connected to the surfaces of the plate 93 and the slider 91. The right end of the short rod 92 is fixedly connected to a pull plate 95. By setting the pull plate 95, pulling it facilitates the short rod 92 and the plate 93 to move, so that the plate 93 is separated from the surface of the circular plate 4. The bottom of the slider 91 is fixedly connected to the target plate 96.

[0026] See also Figure 1 and Figure 4 A mirror 11 is fixedly connected to the right side of the circular plate 4. By setting the mirror 11, it is convenient for teachers to examine their own instruments and maintain a good appearance. An annular T-slot adapted to the slider 91 is opened on the right side of the circular plate 4. By setting the annular T-slot, the slider 91 is limited and the slider 91 can rotate on the circular plate 4.

[0027] When in use, the connecting rope 26 is moved by pulling the pull ring 27, and then the block 25 is moved into the groove 23, and the spring 1 24 is compressed to make the block 25 disengage from the original card hole, and then the vertical rod 22 is pulled to move in the vertical tube 21. After adjustment, the pull ring 27 is loosened and the block 25 is moved in and out of the corresponding card hole under the action of the spring 1 24 rebounding, and the height adjustment and fixation are completed. The fill light angle of the fill light 5 can be adjusted under the action of the damping shaft. By pulling the pull plate 95, the short The rod 92 and the plate 93 move, so that the plate 93 is separated from the circular plate 4 and the spring 2 94 for compression, and the slider 91 is moved on the circular plate 4, so that the target plate 96 moves to the scale 8 of the corresponding value. During the online education class, the operation of the servo motor 65 is controlled for timing. The servo motor 65 drives the rotation of the round block 66 and the rubber ring 67, and then drives the rotation of the rubber ring 63, the circular plate 4 and the pointer 7. As the pointer 7 continues to rotate and contacts the target plate 96, it indicates that the class time is over.

[0028] To sum up: the adjustable fill light for online educational videos is coordinated through the battery base 1, adjustment mechanism 2, connecting plate 3, circular plate 4, fill light 5, drive mechanism 6, pointer 7, scale 8 and target positioning mechanism 9, which solves the problem that when adjusting the height, it is only adjusted by a simple telescopic rod, and the two rods cannot be positioned and fixed, resulting in instability after adjustment, and it does not have the function of time prompt, which makes it impossible for teachers to better control the progress of this class.
