[0030] With reference to Figure 1The inner wall of the desktop U-shaped light shield 25 is fixedly connected with a reading board 26 to provide a comfortable reading auxiliary platform for the user. The top of the desktop U-shaped light shield 25 is fixedly connected with a fixed plate five 27 to provide a convenient condition for the installation and rotation of the reading lamp 28, so as to ensure that the reading lamp 28 can be flexibly adjusted in the illumination angle according to the needs of the user. The top of the platform fixed plate five 27 is rotatably connected with the reading lamp 28 to provide illumination for the user when the light is insufficient.
[0031] Working principle: first, the slider 4 is stationary in the initial position of the slide of the fixed block 3, the locking block 11 tightly locks the sliding groove 6, and the interval control block 5 maintains a certain interval with the main desktop 1. When the user feels that the sitting position distance needs to be adjusted in height, press the button 9, the reset spring 29 at the bottom of the button 9 is compressed under the force, and the elastic potential energy is stored quickly. At the same time, the movable block 8 connected with the top of the button 9 rotates around the connecting shaft 7, driving the bottom locking block 11 to rotate synchronously, and unlocking the sliding groove 6. Then, the user pushes the interval control block 5, because the slider 4 is fixedly connected with it, the slider 4 moves along the sliding groove 6 in the slide of the fixed block 3, driving the interval control block 5 to move up and down, until the distance of two fists width is reached according to the height of the student, which can effectively prevent myopia and scoliosis and other problems. After adjusting to the right position, release the button 9, the reset spring 29 releases energy immediately, pushes the button 9 back to the original position, the movable block 8 returns to the initial angle, and the locking block 11 locks the sliding groove 6 again, locking the slider 4, to ensure that the interval control block 5 is fixed.
[0032] Then, the fixed plate two 12 is stably erected on the top of the main desktop 1, and a plurality of limiting grooves 14 are uniformly distributed on the outer walls of the two vertical limiting side plates 13. The writing board 17 is connected with the limiting block 19 through the fixed plate four 18, and the limiting block 19 can rotate flexibly in the fixed plate four 18 and fit with the limiting groove 14. When the user starts to write or draw and needs to change the writing posture for comfort, rotate the writing board 17, because the rotating shaft 16 is stably fixed in the fixed plate three 15, providing stable support for the rotation of the writing board 17, the writing board 17 can change the angle. During the rotation process, the limiting block 19 is clamped into different limiting grooves 14, so as to fix the required inclination angle of the writing board 17. For example, when writing a long text, the writing board 17 is adjusted to a slight inclination, and the wrist is naturally stretched, which can effectively relieve writing fatigue; when drawing a picture, the inclination angle of the writing board 17 is adjusted to be larger, which is convenient for line drawing, and can help the user to maintain the correct wrist and arm posture in all directions, preventing wrist injury and bad posture.
[0033] The control receiver 23 receives instructions from a remote controller, a control panel, and the like. The instructions cover the user's requirements for raising, lowering, or accurately positioning the desktop. Once the raising instruction is received, the control receiver 23 transmits a signal to the small hydraulic machine 30. The small hydraulic machine 30 serves as the core power source. With the advanced hydraulic technology, the internal precise hydraulic system is started immediately to generate a continuous and strong thrust. Since the top of the push rod 22 and the bottom of the movable leg 20, and the push rod 22 and the internal part of the small hydraulic machine 30 are tightly connected, the push rod 22 is accurately extended or retracted under the action of the thrust. The movable leg 20 is made of a hollow aluminum alloy pipe, which has both strength and lightness. The outer part of the movable leg 20 and the inner part of the fixed leg 21 are highly precisely matched, and the gap is very small. Under the action of the push rod 22, the movable leg 20 smoothly rises along the inner part of the fixed leg 21, and the main desktop 1 is slowly raised.
[0034] Conversely, when the lowering instruction is received, the small hydraulic machine 30 drives the push rod 22 to retract, and the movable leg 20 smoothly slides down in the fixed leg 21, and the height of the main desktop 1 is lowered. During the entire lifting process, the support plate 24 on the outside of the fixed leg 21 stably supports the user's feet, and ensures the stability of the desk during lifting.
[0035] Finally, it should be noted that the above description is only a preferred embodiment of the present application and is not intended to limit the present application. Although the present application 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 replacements to some technical features. Any modification, equivalent replacement, improvement, and the like made within the spirit and principles of the present application shall be included in the protection scope of the present application.
