Description

Technical Field

[0001] This utility model relates to the field of study desks, and more particularly to a study desk that prevents myopia. Background Technology

[0002] In recent years, myopia among teenagers has shown a serious trend of high incidence and younger age of onset, and has become an important public health problem affecting the physical and mental health of teenagers. There are many reasons for myopia among teenagers, among which poor study posture is one of the key factors. Reading and writing at close range for a long time, with the head too low and the eyes too close to the book, can easily lead to the occurrence and development of myopia.

[0003] A study desk for eye protection, disclosed in CN220308666U, includes a base, supporting legs, a desk structure, and an anti-myopia structure. The supporting legs are mounted on the base, and the desk structure is mounted on the supporting legs. This device supports the abdomen with a limiting ring one, while rotating a supporting rod two on a rotating seat to support the chest with the limiting ring two. Adjusting the position of the limiting ring two of the limiting ring one achieves anti-myopia. However, this device requires multiple components to support the abdomen and chest separately, resulting in a complex structure that is difficult to change shape to meet the limiting and support requirements for the chin area. Furthermore, the limiting components cannot be folded up after use, occupying space, making storage inconvenient, and affecting ease of use.

[0004] Therefore, it is necessary to design a myopia-preventing study desk that can adjust the position and angle of the bracket to limit the user's abdomen or chin, thereby preventing myopia, while also making it easy to fold up the bracket and telescopic rod, switch between different modes of use, and reduce the space occupied when not in use. Utility Model Content

[0005] To overcome the shortcomings of the current device, which requires multiple components to support the abdomen and chest, has a complex structure, is difficult to change shape to meet the requirements of limiting and supporting the chin, and cannot retract the limiting components after use, occupying space, being inconvenient to store, and affecting the ease of use, this utility model provides a myopia-preventing study table that can adjust the position and angle of the bracket to limit the user's abdomen or chin to prevent myopia, while also making it easy to retract the bracket and telescopic rod, facilitating switching between different forms of use, and reducing the space occupied when not in use.

[0006] An anti-myopia study desk includes a desktop, anti-collision strips, legs, a base, latches, trays, brackets, telescopic rods, sliders, limiting components, and fixing components. Anti-collision strips are connected to the outer side of the desktop. Legs are slidably connected to the lower sides of both the left and right sides of the desktop. A base is connected to the lower side of each leg, and latches are engaged with the desktop. Trays are slidably connected to both the left and right sides of the desktop.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] A type of anti-myopia study desk, such as Figures 1-5 As shown, the device includes a desktop 1, a bumper strip 2, legs 3, a base 4, a locking pin 5, a tray 6, a bracket 7, a telescopic rod 8, a slider 9, a limiting component, and a fixing component. The bumper strip 2 is connected to the outer side of the desktop 1. Legs 3 are slidably connected to the lower sides of both the left and right sides of the desktop 1. The lower side of each leg 3 is connected to a base 4. Each leg 3 is locked with a locking pin 5, which is engaged with the desktop 1. Each tray 6 is slidably connected to the left and right sides of the desktop 1. Each tray 6 has a handle on its front side for easy gripping and pulling. A slider 9 is slidably connected to the middle of the desktop 1. A telescopic rod 8 is rotatably connected to the slider 9. A bracket 7 is connected to the telescopic end of the telescopic rod 8. The bracket 7 is arc-shaped to fit the user's chin. A limiting component is provided on the telescopic rod 8 to fix the position of the bracket 7. A fixing component is provided between the telescopic rod 8 and the slider 9 to fix the angle of the telescopic rod 8.

[0022] like Figure 4As shown, the limiting component includes a first locking block 11 and a first spring 12. The first locking block 11 is slidably connected to the right side of the fixed end of the telescopic rod 8. The first locking block 11 engages with the telescopic end of the telescopic rod 8. The first spring 12 is connected between the first locking block 11 and the fixed end of the telescopic rod 8. It also includes a pull ring 10. The pull ring 10 is connected to the right side of the first locking block 11, which makes it easy to pull the first locking block 11 by hand.

[0023] like Figure 3 and Figure 5 As shown, the fixing component includes a second spring 13, a second locking block 14 and a gear 15. The left and right sides of the fixed end of the telescopic rod 8 are slidably connected to the second locking block 14. The second locking block 14 is connected to the left and right sides of the fixed end of the telescopic rod 8 by two second springs 13. The left and right sides of the slider 9 are connected to the gear 15. The second locking block 14 is engaged with the gear 15 on the same side.

[0024] When writing or studying, this device can be used. The base 4 is brought into contact with the ground. Then, depending on the user's height, the latch 5 is removed by hand. The tabletop 1 is then moved along the support leg 3 to a suitable height. The latch 5 is then engaged with the support leg 3 and the tabletop 1 for fixation. After fixing, the stool is moved to the front of the tabletop 1. The user sits on the stool and places the book on the tabletop 1. The tray 6 is then pulled to unfold. Depending on the situation, the bracket 7 is pulled to move the telescopic rod 8, which in turn moves the slider 9. Then, the user... Pulling ring 10 moves the first locking block 11, compressing the first spring 12, and then pulling the telescopic rod 8 to extend it. After extension, releasing pull ring 10 causes the first spring 12 to rebound, and the first locking block 11 moves back to its original position and engages with the fixed end of the telescopic rod 8 for fixation. Then, pushing bracket 7 and telescopic rod 8 to move back to their original positions causes slider 9 to move back to its original position. Subsequently, bracket 7 limits the user's abdomen, thereby restricting the distance between the user and the tabletop 1. Alternatively, the above operation can be repeated to move bracket 7 and telescopic rod 8 out, extend and fix telescopic rod 8, and then rotate telescopic rod 8 to cause the second locking block 11 to move back to its original position. After being repeatedly squeezed, block 14 resets and engages with gear 15. The second spring 13 rebounds after being squeezed, thus fixing the angle of the telescopic rod 8. This, in turn, supports the user's chin via bracket 7 and limits its movement, preventing myopia. Bracket 7 is arc-shaped. The user then places their hands on the tray 6 to correct their posture before starting to write. This allows for adjustment of the desktop height for studying while simultaneously correcting the user's posture by supporting their arms, reducing strain on the shoulders, neck, and arms, improving learning efficiency, preventing incorrect posture, and enhancing user comfort. After use, pull the first locking block 11 by the pull ring 10 to move it, the first spring 12 is squeezed, and then push the telescopic rod 8 to retract and return to its original position. Then release the pull ring 10, the first spring 12 rebounds, the first locking block 11 moves back to its original position and contacts the fixed end of the telescopic rod 8, and then push the bracket 7 and the telescopic rod 8 to move in the opposite direction to retract. This allows the position and angle of the bracket 7 to be adjusted to limit the user's abdomen or chin to prevent myopia, while also making it convenient to retract the bracket 7 and the telescopic rod 8, facilitating the switching between different modes of use and reducing the space occupied when not in use. Then push the tray 6 to move and retract it.
