Wooden desk is a very common type of wooden table, which is widely loved by consumers due to its natural, environmentally friendly and beautiful characteristics. The surface of the wooden desk is usually connected with a bookshelf, and learning books and extracurricular books can be placed on the bookshelf.
[0003] The desktop of the wooden desk is often designed to be fixed and lacks flexibility. For students, this design is particularly inconvenient when reading. When they need to carefully read textbooks or reference materials, they often find that the books cannot be naturally inclined to adapt to the best reading angle. This causes them to have to hold the books for a long time, and their arms are prone to feel sore. Or they have to bend their backs and lower their heads to see the words clearly, and long-term bending may cause neck and vision problems. Therefore, this limitation of the wooden desk in use, especially for students who need to read a lot, indeed brings a lot of trouble and inconvenience. SUMMARY

[0026] When in use, the wooden table can be used to store study materials and extracurricular books via bookshelf 3, and can be used by students for studying via the tabletop 2.
[0027] Preferably, the desktop 5 forms a rotating structure with the tabletop 2 through the first hinge 4, and the center of the arc-shaped groove 9 is located on the central axis of the first hinge 4.
[0028] In practical use, when the desktop 5 is subjected to tension, it can rotate along the central axis of the first hinge 4, thereby adjusting the angle of the desktop 5 so that books can be placed on the desktop 5, making it convenient for students to read.
[0029] Preferably, the first screw 6, the screw sleeve 7, the rubber ring 8 and the arc-shaped sliding groove 9 are symmetrically arranged on both sides of the tabletop 5. The screw sleeve 7 and the first screw 6 are connected by a thread, and the screw sleeve 7 is slidably connected to the bookshelf 3 through the arc-shaped sliding groove 9.
[0030] In practical use, when the desktop 5 rotates, the first screw 6 can drive the screw sleeve 7 to slide inside the arc-shaped groove 9, which can maintain the stability of the desktop 5 rotation.
[0031] Preferably: a second hinge 10 is installed on the side surface of the tabletop 2, an extension plate 11 is connected to the side surface of the second hinge 10, a guide rail 12 is connected to the bottom side of the tabletop 2, a sliding sleeve 13 is sleeved on the surface of the guide rail 12, a connecting frame 14 is connected to the bottom side of the sliding sleeve 13, the connecting frame 14 extends through the side surface of the table leg 1, a bearing ring 15 is fitted on the side surface of the connecting frame 14, a threaded rod 16 is connected through the inside of the bearing ring 15, a movable leg 17 is connected to the end of the connecting frame 14, a caster wheel 18 is installed on the bottom side of the movable leg 17, and a threaded tube 19 is connected through the table leg 1 sleeved on the threaded rod 16.
[0032] Preferably, the extension plate 11 forms a flip structure with the tabletop 2 via the second hinge 10.
[0033] In practical use, when the extension plate 11 is subjected to tension, it can be flipped through the second hinge 10, thereby increasing the usable area of the wooden table through the flipped extension plate 11.
[0034] Preferably, the guide rail 12 and the sliding sleeve 13 are symmetrically arranged on both sides of the connecting frame 14, and the sliding sleeve 13 and the guide rail 12 are slidably connected.
[0035] In practical use, when the connecting frame 14 is subjected to a force, it can drive the sliding sleeve 13 to slide on the surface of the guide rail 12, which can limit the movement direction of the connecting frame 14.

[0038] Working principle: When using this wooden table, when a student needs to read, the screw sleeve 7 can be rotated first. When the screw sleeve 7 rotates on the surface of the first screw 6, it can move away from the tabletop 5. Then, the tabletop 5 can be pulled to rotate along the central axis of the first hinge 4. After the tabletop 5 rotates to a suitable angle, the screw sleeve 7 can be rotated in the opposite direction. When the screw sleeve 7 rotates in the opposite direction on the surface of the first screw 6, it can move closer to the tabletop 5. When the screw sleeve 7 drives the rubber ring 8 to move to the surface of the bookshelf 3, the position of the screw sleeve 7 can be fixed by the friction between the rubber ring 8 and the bookshelf 3. In this way, the position of the tabletop 5 is fixed by the screw sleeve 7 and the first screw 6, so that books can be placed on the tabletop 5 for reading.
[0039] When the wooden table needs to be used by multiple people, the threaded rod 16 can be rotated. When the threaded rod 16 rotates inside the threaded tube 19, it can move laterally. The lateral movement of the threaded rod 16 can drive the connecting frame 14 to move laterally through the bearing ring 15. The lateral movement of the connecting frame 14 can drive the casters 18 to roll away from the table legs 1 through the movable legs 17. Then the extension plate 11 can be pulled to flip it. When the extension plate 11 is flipped 180°, the usable area of the wooden table can be expanded, so that multiple people can use it at the same time.
[0040] Finally, it should be noted that the above are merely preferred embodiments of this utility model and are not intended to limit the utility model. Although the utility model 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 substitutions for some of the technical features.
