[0015] After adopting the above structure, the grooves provided on the desk surface of the utility model can be used to place stationery such as pens, rulers, erasers, etc., so that the stationery will not slide off when the desk surface is used in a tilted state.
[0016] The working principle of the desk table tilt angle adjustment device of the present invention is as follows: when the desk table needs to be adjusted to a tilted state, the adjusting handle is lifted up to drive the L-shaped rotating limit plate to rotate, so that the L-shaped rotating limit plate is disengaged from the hook portion below the ㄣ-shaped fixed limiting plate, and then the table panel is tilted by pressing down the rear end or lifting the front end of the table panel, and the table panel is rotated through the hinge. When the hinge is rotated to the tilted limit portion close to the book pocket, the adjusting handle is released at this time, and the restoring force of the torsion spring drives the L-shaped rotating limit plate to rotate, so that the bottom of the L-shaped rotating limit plate is vertically and horizontally supported on the flat support portion in the middle of the ㄣ-shaped fixed limiting plate, and the side surface of the bottom of the L-shaped rotating limit plate is pressed against the side surface above the fixed limiting plate by the restoring force of the torsion spring, so that it will not move, and the supporting structure is prevented from loosening, so that the desk can be used in the tilted state as stably as in the flat state. When the desk surface needs to be adjusted back to a flat state, the adjustment handle is similarly lifted to drive the L-shaped rotating limit plate to rotate, so that the L-shaped rotating limit plate leaves the flat support portion in the middle of the U-shaped fixed limit plate. Then, by pressing down on the front end of the table panel, the table panel and the book pocket are supported horizontally and flatly. Finally, the adjustment handle is released, and the restoring force of the torsion spring drives the L-shaped rotating limit plate to rotate, so that the L-shaped rotating limit plate is hooked tightly to the hook portion below the U-shaped fixed limit plate, and is not easy to loosen or move, restoring the normal flatness of the desk surface. The adjustment handle of the utility model uses the same action to adjust the tilt angle and flatness angle of the desk surface, and the adjustment operation is simple, convenient, and quick.

[0033] The present invention will be further described below with reference to the accompanying drawings.
[0034] See Figures 1 to 4 As shown, the technical solution adopted in this specific embodiment is:
[0035] A device for adjusting the tilt angle of a desk table top comprises a desk frame 1, a book pocket 2, a desk panel 3, and a tilt adjustment component. The book pocket 2 has a rotating groove 21 and a limiting groove 22 on both sides and is fixed to the bottom of the top of the desk frame 1. The two sides below the middle and rear ends of the desk panel 3 are connected to the desk frame 1 for positioning and rotation through hinges 10, and the two sides below the middle and front ends are connected to the book pocket 2 for tilting and limiting. The tilt adjustment component comprises a rotating bracket 4, a rotating shaft 5, a rotating limiting piece 6, a fixed limiting piece 7, and an adjusting handle 8. The rotating bracket 4 is fixed below the desk panel 3 and is rotatably connected to the rotating shaft 5. Rotating limiting pieces 6 are fixed at both ends of the rotating shaft 5. The fixed limiting piece 7 is provided with a hook portion and a plane support portion and is fixed in the limiting groove 22 of the book pocket 2. The adjusting handle 8 is fixed at the end of the rotating shaft 5. The rotating limiting piece 6 is rotated by rotating the adjusting handle 8, and cooperates with the hook portion or the plane support portion of the fixed limiting piece 7 to make the desk panel flat or tilted. The desk in this embodiment utilizes the aforementioned tilt adjustment assembly's rotating stopper 6 and fixed stopper 7 to adjust the tabletop 3 to either level or tilt it, facilitating reading and writing for children while reducing strain on the neck, back, and eyes, improving learning efficiency, and helping them maintain a correct sitting posture and prevent health issues associated with poor posture (such as scoliosis). The tilt angle adjustment device of this utility model features a simple and compact structure, saving space for book pockets. The tilt adjustment is quick and easy, positioning and assembly are efficient, and the tilt support structure is stable.
[0036] In this embodiment, the tilt adjustment assembly further includes a torsion spring 9, which is sleeved onto the rotating shaft 5 and cooperates with the adjustment handle 8 to automatically reset. This embodiment utilizes the restoring force of the torsion spring 9 to securely hook and support the rotating stopper 6 on the fixed stopper 7, preventing it from loosening or shifting. The adjustment handle 8 automatically resets after adjusting the flatness or tilt angle of the tabletop 3, eliminating the need for manual adjustment and making adjustments simple and convenient.
[0037] In this specific embodiment, the rotating limit piece 6 is generally L-shaped, and the fixed limit piece 7 is generally U-shaped. In this specific embodiment, the tabletop 3 can be adjusted to a flat state by hooking the L-shaped rotating limit piece 6 on the hook portion below the U-shaped fixed limit piece 7, so that the desk surface will not shake during use. In this specific embodiment, the tabletop 3 can also be adjusted to an inclined state by rotating the L-shaped rotating limit piece 6 so that its bottom is supported on the flat support portion in the middle of the U-shaped fixed limit piece 7, so that the inclined state of the desk is as stable as the flat state.
[0038] In this embodiment, the book pocket 2 is provided with tilt limiters 23 on both sides of the rear end. The tilt limiters 23 of the book pocket 2 in this embodiment can limit the rotation angle of the hinge 10, thereby limiting the tilt angle of the table panel 3, making it convenient to press down or lift the table panel 3 to adjust the tilt angle of the desk, and preventing the desk panel 3 from tilting excessively.
[0039] In this embodiment, a circular groove and a rectangular groove are provided on the table panel 3. The grooves provided on the desk surface of this embodiment can be used to place stationery such as pens, rulers, erasers, etc., so that the stationery will not slide off when the desk surface is used in an inclined state.
[0040] The working principle of this specific embodiment is as follows: when the desk surface needs to be adjusted to an inclined state, the adjusting handle 8 is lifted to drive the L-shaped rotating limit plate 6 to rotate, so that the L-shaped rotating limit plate 6 disengages the hook portion below the ㄣshaped fixed limiting plate 7, and then the table panel 3 is tilted by pressing down the rear end or lifting the front end of the table panel 3. The table panel 3 rotates through the hinge 10. When the hinge 10 rotates to the inclined limit portion 23 close to the book pocket 2, the adjusting handle 8 is released at this time, and the restoring force of the torsion spring 9 drives the L-shaped rotating limit plate 6 to rotate, so that the bottom of the L-shaped rotating limit plate 6 is vertically and horizontally supported on the flat support portion in the middle of the ㄣshaped fixed limiting plate 7, and the side surface of the bottom 6 of the L-shaped rotating limit plate is pressed against the side surface above the fixed limiting plate 7 by the restoring force of the torsion spring, so that it will not move, avoiding the loosening of the supporting structure, thereby achieving the same stability of using the desk in the inclined state as in the flat state. When the desk surface needs to be adjusted back to a flat state, the adjusting handle 8 is similarly lifted to drive the L-shaped rotating limit plate 6 to rotate, so that the L-shaped rotating limit plate 6 leaves the flat support portion in the middle of the U-shaped fixed limit plate 7. Then, by pressing down on the front end of the table panel 3, the table panel 3 and the book pocket 2 are supported horizontally and flatly. Finally, the adjusting handle 8 is released, and the restoring force of the torsion spring 9 drives the L-shaped rotating limit plate 6 to rotate, so that the L-shaped rotating limit plate 6 is hooked tightly to the hook portion below the U-shaped fixed limit plate 7, and is not easy to loosen or move, restoring the desk surface to normal flat use. The adjusting handle 8 of the utility model adopts the same action to adjust the inclination angle and flatness angle of the desk surface, and the adjustment operation is simple, convenient and fast.
