DETAILED DESCRIPTION

[0026] like Figure 1 As shown, a table with vision restoration function includes a control table 10, and a drawer 11 is slidably connected to the front of the control table 10. The drawer 11 is used to place students' books, stationery, etc., and a handle 12 is fixedly connected to the front of the drawer 11; the top of the control table 10 is installed with a mechanism for protecting eyesight.

[0027] Preferably, the length of the handle 12 allows the user to maintain a suitable distance from the table after sitting down, thereby preventing the student from fitting closely to the desk and maintaining the student's sitting posture while doing homework.

[0028] refer to Figure 1 , 2 7. A flip groove 20 is provided at the rear side of the top of the control table 10, and a flip rod 21 is rotatably connected to the left and right sides of the inside of the flip groove 20, and a flip block 22 is fixedly connected to the surface of the flip rod 21, and a protective box 23 is fixedly connected to the top of the flip block 22, and a rotating rod 24 is rotatably connected to the left and right sides of the inside of the protective box 23, and an adjustable angle fixed block 25 is fixedly connected to the rotating rod 24, and an adjusting block 26 is fixedly connected to the top of the fixed block 25, and a rotating groove 27 is provided on the front of the adjusting block 26, and a bidirectional threaded rod 28 is rotatably connected to the left and right sides of the inside of the rotating groove 27, and a vision repair box 29 is threadedly connected to the left and right sides of the bidirectional threaded rod 28.

[0029] Preferably, the length of the vision repair box 29 is matched with the length of the rotating slot 27, so as to achieve the effect of guiding the vision repair box 29 when it moves, and the vision repair box 29 can emit far-red light from the front after power is turned on (the above is the prior art and will not be described in detail here). When in use, the angles of the fixed block 25 and the vision repair box 29 are adjusted according to the height of the user, and then the distance between the two vision repair boxes 29 is adjusted according to the distance between the user's eyes.

[0030] When in use, by rotating the bidirectional threaded rod 28, the bidirectional threaded rod 28 drives the two vision repair boxes 29 to move parallel to or away from each other until the two vision repair boxes 29 face the user's eyes. At the same time, the vision repair box 29 is started by an external power supply, and the vision repair box 29 emits red light to repair the user's eye tissue, thereby achieving the effect of protecting myopia.

[0031] Specifically, the protective box 23 has a one-way threaded rod 30 rotatably connected to the front and rear sides, and a moving block 31 is threadedly connected to the one-way threaded rod 30, and a tilting rod 32 is fixedly connected to the top of the moving block 31; a pair of clamping blocks 33 are fixedly connected to the rear side of the adjustment block 26, and the opposite sides of the pair of clamping blocks 33 are rotatably connected to the moving block 31 through a movable shaft. When in use, the one-way threaded rod 30 is manually rotated, and the one-way threaded rod 30 drives the moving block 31 to move. When the one-way threaded rod 30 rotates clockwise, it drives the moving block 31 to move forward, thereby driving the tilting rod 32 to move forward, so that the angle between the tilting rod 32 and the adjustment block 26 is smaller, and the adjustment block 26 and the vision repair box 29 are flipped forward. Similarly, the one-way threaded rod 30 is rotated in the opposite direction, which can drive the moving block 31 to move backward, so that the adjustment block 26 and the vision repair box 29 are flipped backward, thereby achieving the effect of adjusting the angle of the vision repair box 29.

[0032] During the use of the prevention and control table 10, since there are usually multiple reference books on the desktop, they will cover the entire desk. If the desk is to be placed with an eye protection lamp, there will be insufficient space, and the best position for placing the eye protection lamp coincides with the position of the protection box 23. In order to meet the needs of both, a flip mechanism is proposed.

[0033] refer to Figure 3 A foldable eye protection lamp 40 is fixedly connected to the bottom of the flip rod 21. When in use, the foldable eye protection lamp 40 and the protective box 23 are replaced by manipulating the flip rod 21, so that the foldable eye protection lamp 40 is flipped upward when the user is studying or writing, and the protective box 23 is flipped upward after writing or studying, and the vision repair box 29 is used for myopia protection.

[0034] Preferably, a ceiling light 70 is installed at the top left boundary of the control table 10. The ceiling light 70 is relatively high and the lamp head is adjustable. Together with the foldable eye protection lamp 40, it can effectively illuminate the surface of the desk, further increasing the user's comfort when reading.

[0035] refer to Figure 4 , 56. The control table 10 has active rods 50 rotatably connected to the front and rear sides of the left side inside. The two active rods 50 are fixedly connected to the first synchronous pulleys 51, and the outer sides of the two first synchronous pulleys 51 are meshed with first transmission belts 52 that can move in one direction; a driving groove 56 is opened at the left end of the top side of the interior of the control table 10, and the left end of the flip rod 21 extends to the left and is rotatably connected to the left and right sides of the driving groove 56. A second synchronous pulley 57 is fixedly connected to the flip rod 21, and the second synchronous pulley 57 is arranged inside the driving groove 56. The right side of the active rod 50 on the rear side is fixedly connected to the same second synchronous pulley 57, and the outer sides of the two second synchronous pulleys 57 are meshed with second transmission belts 55.

[0036] When in use, the first transmission belt 52 that only moves backward in one direction drives the two first synchronous pulleys 51 to rotate clockwise, thereby driving the two active rods 50 to rotate in the same direction, thereby driving the second synchronous pulleys 57 to rotate in the same direction, and the second transmission belt 55 and the two second synchronous pulleys 57 cooperate to drive the flip rod 21 to rotate. In this way, the positions of the folding eye protection lamp 40 and the protection box 23 are exchanged.

[0037] Specifically, a group of driving teeth 53 is fixedly connected to the outer surface of the first transmission belt 52, and the left and right sides of the driving gear 53 are designed with arc-shaped teeth; a positioning block 60 is fixedly connected to the front side of the drawer 11, and a support plate 61 is fixedly connected to the right side of the front of the positioning block 60, and a positioning rod 62 is fixedly connected to the bottom left side of the front of the positioning block 60, and a fixed point block 63 is rotatably connected to the surface of the positioning rod 62, and the left bottom of the fixed point block 63 is an arc that fits the right side surface of the driving tooth 53.

[0038] Preferably, a support spring 64 is fixedly connected to the left side of the support plate 61, and the left side of the support spring 64 is fixedly connected to the positioning rod 62; a stop block 65 is fixedly connected to the bottom of the left side of the support plate 61. When the drawer 11 is pulled out to the right, the drawer 11 drives the positioning block 60 to move in the same direction, and at the same time drives the fixed point block 63 to pass over the driving teeth 53. Since the two sides of the driving teeth 53 are designed in an arc shape, when the fixed point block 63 moves to the right, the right side of the fixed point block 63 contacts the arc surface of the driving teeth 53, and the contact force causes the fixed point block 63 to flip to the left, driving the support spring 64 to stretch. When the fixed point block 63 passes over one driving tooth 53, the support spring 64 retracts and drives the fixed point block 63 to rotate in the opposite direction and embed between the two driving teeth 53. When the drawer 11 is pushed to the left, the drawer 11 drives the positioning block 60 and the fixed block 63 to move to the left. Since the fixed block 63 is embedded between two adjacent driving teeth 53 and the left side of the fixed block 63 is in contact with the right side surface of the driving tooth 53, the contact force causes the fixed block 63 to move to the right. After the fixed block 63 flips to the right and abuts against the abutment block 65, it cannot flip to the right. The leftward pushing force of the fixed block 63 drives the first transmission belt 52 to move.

[0039] Before the user reads and writes, the drawer 11 is pulled to the right to take out books and stationery. When the drawer 11 is pushed back to the left after taking out the stationery, the folding eye protection lamp 40 can be flipped to the top, and the opening of the folding eye protection lamp 40 can simulate natural light, provide stable and non-stroboscopic light, reduce stimulation to the eyes, and thus help to reduce eye fatigue after long-term reading, writing or other tasks that require concentration. Secondly, the folding eye protection lamp 40 can improve the visual effect. High-quality eye protection lamps provide high color rendering and color authenticity, making pictures and text clearer, which helps to improve the efficiency of reading and learning. When the user finishes reading, the drawer 11 is pulled to the right again, and the stationery and books are placed back in the drawer 11. When the drawer 11 is pushed back, the protective box 23 can be flipped to the top, and finally the eyes are repaired through the vision repair box 29. The above process not only allows users to develop good reading habits, but also the device occupies less space on the surface of the prevention and control table 10, and there is a larger area to place the corresponding reference books.

[0040] The working principle of the present invention is: by manually rotating the one-way threaded rod 30, the one-way threaded rod 30 drives the moving block 31 to move, and when the one-way threaded rod 30 rotates clockwise, it drives the moving block 31 to move forward, thereby driving the tilting rod 32 to move forward, so that the angle between the tilting rod 32 and the adjustment block 26 is smaller, and the adjustment block 26 and the vision repair box 29 are turned forward. Similarly, rotating the one-way threaded rod 30 in the opposite direction can drive the moving block 31 to move backward, so that the adjustment block 26 and the vision repair box 29 are turned backward, thereby achieving the effect of adjusting the angle of the vision repair box 29.

[0041] Then, the angles of the fixing block 25 and the vision repair box 29 are adjusted according to the height of the user, and then the distance between the two vision repair boxes 29 is adjusted according to the distance between the user's eyes. Finally, the vision repair box 29 is started by an external power supply, and the vision repair box 29 emits far-infrared light from the front to repair the user's eye tissue.

[0042] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments, and the above embodiments and descriptions are only for explaining the principles of the present invention. Without departing from the spirit and scope of the present invention, the present invention may have various changes and improvements, and these changes and improvements all fall within the scope of the present invention to be protected.
