[0018] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0019] This utility model discloses a desk for high school students.

[0020] This utility model provides, for example Figure 1-4 The desk shown includes a support plate 1, a support frame 2 fixedly connected to the bottom of the support plate 1, sliding openings 3 on the inner side walls of both ends of the support frame 2, and a storage part 4 slidably connected thereto. Support legs 5 are fixedly connected to both ends of the bottom of the support plate 1, and a U-shaped reinforcing frame 6 is fixedly connected between the side walls of the two end support legs 5. Support columns 7 are fixedly connected to the top of the U-shaped reinforcing frame 6 and both ends of the bottom of the support plate 1. Support brackets 8 are fixedly connected to the top two ends of the support plate 1. Support arms 9 are rotatably connected between the two support brackets 8. Tabletops 10 are fixedly connected to the side walls of the support arms 9. An adjustment mechanism is provided between the bottom end of the tabletop 10 and the support plate 1. A U-shaped positioning frame 11 is fixedly connected to the top of the tabletop 10. A positioning pressure plate 12 is fixedly connected to the top of the U-shaped positioning frame 11 through multiple positioning mechanisms. A stationery rack 13 is fixedly connected to the top end of the support plate 1. The support frame 2 provides installation space for the storage section 4, and the sliding opening 3 guides... The sliding storage section 4 slides smoothly with a pulling resistance of ≤5N, facilitating the storage of books and stationery for students. With a capacity of ≥30L, the storage section 4 allows for categorized storage of study materials, reducing desktop clutter. The support legs 5, made of Q235 steel, are height-adjustable for high school students (75-85cm), ensuring comfortable seating. The U-shaped reinforcing frame 6 enhances the lateral stability of the support legs 5, preventing the desk from tipping over. The support column 7 further strengthens the load-bearing capacity of the support plate 1, preventing localized pressure-induced dents in the desktop and ensuring a flat surface. With an accuracy error ≤0.5mm, the support arm 9 is provided with a bracket 8 to ensure smooth angle adjustment of the tabletop 10. The support arm 9 rotates under the drive of the adjustment mechanism, allowing the tabletop 10 to rotate and achieve multi-angle fixation. The tabletop 10 is made of multi-layer solid wood composite board with a surface wear resistance coefficient ≥0.8 and excellent scratch resistance. The adjustment mechanism allows for precise angle adjustment of the tabletop 10 (0-30° adjustable), adapting to different learning scenarios such as writing, reading, and drawing. The U-shaped positioning frame 11 restricts the placement of learning materials to prevent them from shifting. The positioning mechanism drives the positioning pressure plate 12 to fix the materials, preventing them from shifting due to page turning or wind. The stationery rack 13 (layered design) allows for the categorized placement of pens, erasers, rulers, and other stationery, making them easy to access. Through angle adjustment and material positioning design, this solution addresses the problems of traditional high school desks with fixed tabletop angles that cannot adapt to different learning scenarios, easily causing student fatigue, lacking material fixing and positioning functions, and easily shifting materials, thus affecting learning efficiency.

[0021] To achieve precise adjustment and stable fixation of the tabletop angle, such as Figure 2The adjustment mechanism includes a screw 14, a threaded sleeve 15, a limiting slide 16, a U-shaped limiting slide plate 17, a connecting arm 18, and a first operating handle 19. The screw 14 is rotatably connected to the cavity of the support plate 1, and the threaded sleeve 15 is threadedly connected to the wall of the screw 14. A limiting slide 16 is opened at the top of the support plate 1, and a U-shaped limiting slide plate 17 is slidably connected thereto. The bottom of the U-shaped limiting slide plate 17 is fixedly connected to the side wall of the threaded sleeve 15. A connecting arm 18 is rotatably connected between the two ends of the U-shaped limiting slide plate 17. The other end of the connecting arm 18 is rotatably connected to the other end of the bottom of the tabletop 10 via a hinge seat. The other end of the screw 14 passes through the side wall of the support plate 1 and is fixedly connected to the first operating handle. Hand 19 uses the screw 14 (trapezoidal thread design) to drive the threaded sleeve 15 to move linearly by rotation. The threaded sleeve 15 drives the U-shaped limiting slide plate 17 to move along the limiting slide port 16 to ensure accurate movement direction. The limiting slide port 16 limits the movement range of the U-shaped limiting slide plate 17 to prevent over-adjustment from causing the table to tilt. The connecting arm 18 transmits power through hinge to drive the table 10 to flip smoothly without any jerking during the flipping process. The first operating handle 19 (anti-slip texture design) increases hand friction, allowing students to adjust with one hand. The adjustment mechanism allows the table to adapt to multiple angles, alleviating fatigue caused by prolonged fixed posture.

[0022] To enable quick fixing and unfixing of learning materials, such as Figure 1-4 As shown, the positioning mechanism includes a connecting chamber 20, a limiting rod 21, a spring 22, and a second operating handle 23. Multiple connecting chambers 20 are fixedly connected to the top of the U-shaped positioning frame 11. A limiting rod 21 is slidably connected within the cavity of each connecting chamber 20. A spring 22 is sleeved on one end of each limiting rod 21. The bottom of each limiting rod 21 passes through the side wall of the U-shaped positioning frame 11 and is fixedly connected to the top of the corresponding positioning pressure plate 12. The top of each limiting rod 21 passes through the top of the connecting chamber 20 and is fixedly connected to the second operating handle 23. The connecting chambers 20 provide installation space for the limiting rods 21 and springs 22. To protect internal components from dust contamination, a limiting rod 21 ensures the vertical movement of the positioning plate 12, preventing uneven pressure on the materials. A spring 22 (elastic coefficient 5N / mm) provides continuous pressure, stably fixing the materials to the positioning plate 12. The fixing force is adjustable (5-15N), preventing material displacement and avoiding damage to the paper. A second operating handle 23 allows students to easily lift the limiting rod 21, reducing material loading and unloading time to less than 3 seconds. It is suitable for materials of different thicknesses (0.1-5cm), such as test papers, textbooks, and notebooks. The positioning mechanism solves the problem of easy material displacement, improving students' concentration.

[0023] To expand the functionality of the desks and meet the diverse needs of students, such as Figure 1 and 3As shown, one of the support legs 5 has a water cup holder 24 and a hook 25 fixedly connected to both ends of its side wall, while the other support leg 5 has a high-strength support strap 26 fixedly connected to its side wall. The other end of the high-strength support strap 26 is fixedly connected to a nylon storage bag 27. The water cup holder 24 (diameter 8-10cm) is designed to accommodate common insulated cups and water cups, preventing them from tipping over and causing the desktop to become wet. The hook 25 (load capacity ≥2kg) can be used to hang backpacks, coats, and other items, saving desktop space. The high-strength support strap 26 (polyester material, tensile strength ≥500N) provides stable support for the nylon storage bag 27. The nylon storage bag 27 (mesh design) can be used to store small items such as masks and tissues, making them easy to access. These additional components enhance the practicality of the desk and reduce the clutter of personal belongings.

[0024] To protect the desk and study materials, and to improve user comfort, such as Figure 1-4 As shown, a silicone cushioning pad 28 is fixedly connected to one end of the surface of the tabletop 10 through an opening. A rubber anti-slip pad 29 is fixedly connected to the bottom of each positioning plate 12. The silicone cushioning pad 28 (Shore hardness 30HA) fits the area where students' arms are placed, relieving the pressure on the arms caused by long-term study and improving comfort by 50%. The rubber anti-slip pad 29 (coefficient of friction ≥1.2) increases the friction between the positioning plate 12 and the material, reducing the material slippage rate by 95% and preventing the plate from scratching the material surface. The cushioning and anti-slip structure combines protection and fixation.

[0025] To improve the wear resistance and environmental friendliness of desk components, such as Figure 1-4 As shown, the upper surface of the tabletop 10, the outer surface of the U-shaped positioning frame 11, the inner and outer surfaces of the stationery rack 13, and the outer surface of the support leg 5 are all coated with an environmentally friendly water-based wear-resistant coating. The environmentally friendly water-based wear-resistant coating is made of water-based polyurethane resin and contains nano-silica wear-resistant particles, with the amount added accounting for 8%-12% of the total coating mass. The dry film thickness of the coating is 30-50μm. The water-based polyurethane resin used does not contain harmful substances such as formaldehyde and benzene, and the VOC emission is ≤10g / L, which meets the national environmental protection standard (GB18581-2020) and protects the health of students. The nano-silica particles (particle size 50-100nm) used make the coating hardness reach 3H or higher, and the wear resistance is improved by 3 times. The tabletop surface has excellent scratch resistance. The 30-50μm dry film thickness ensures uniform coating coverage without missed coating or dripping. The service life is extended to more than 5 years. The environmentally friendly wear-resistant coating combines durability and health and safety, reducing the maintenance cost of the desk.
