[0027] 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.

[0028] This utility model provides, for example Figures 1-5 The illustrated study desk with a multi-angle rotating desktop includes:

[0029] Two sets of support legs 1, a desktop body 2, and a table hole frame 3. The table hole frame 3 is installed between the two sets of support legs 1, and the desktop body 2 is installed above the table hole frame 3 and the support legs 1.

[0030] The desktop body 2 includes a first panel 21 and a second panel 22. A fixed base 4 is fixed to the top of the support leg 1. The second panel 22 is fixed to the top of the fixed base 4. A movable support block 5 is movably arranged above the fixed base 4. A movable plate 6 is fixed to one side of the movable support block 5. The end of the movable plate 6 away from the movable support block 5 extends into the inner cavity of the fixed base 4. The first panel 21 is located above the movable support block 5. A support rod 7 is movably connected to the bottom of the first panel 21 through a mounting seat. The end of the support rod 7 away from the first panel 21 is rotatably connected to the fixed base 4.

[0031] A limit adjustment component 8 is provided between the movable plate 6 and the fixed base 4;

[0032] The movable support block 5 is equipped with a deflection limiting component 9 that restricts the flipping of the first panel 21;

[0033] By lifting the first panel 21 upwards, the first panel 21 is flipped around the movable support block 5. Then, under the support and traction of the support rod 7, the movable support block 5 and the movable plate 6 slide on the fixed seat 4, allowing for multi-angle adjustment of the first panel 21. After adjusting to a suitable angle, the limiting bolt 81 is tightened to limit and fix the movable plate 6 to the fixed seat 4. This effectively prevents the first panel 21 from collapsing under pressure, ensuring the safety and stability of the study table. At the same time, the limiting bolt 81 is placed below the fixed seats 4 on both sides for convenient operation by students.

[0034] Among them, such as Figure 2-4 As shown:

[0035] The limit adjustment assembly 8 includes two sets of limit bolts 81. The bottom of the fixed seat 4 has a through slot 82, and the movable plate 6 has two sets of threaded holes 83. The limit bolts 81 pass through the slot 82 from the bottom of the fixed seat 4 and are threadedly connected to the threaded holes 83. The limit bolts 81 pass through the slot 82 from the bottom of the fixed seat 4 and are connected to the movable plate 6 through the threaded holes 83. After tightening the limit bolts 81, the movable plate 6 and the fixed seat 4 can be locked to prevent the movable plate 6 from sliding on the fixed seat 4.

[0036] Furthermore, such as Figure 5 As shown:

[0037] The deflection limiting component 9 includes an arc-shaped groove 91 formed inside the movable support block 5. An arc-shaped component 92 is slidably disposed in the inner cavity of the arc-shaped groove 91. The top of the arc-shaped component 92 passes through the arc-shaped groove 91 and is fixed to the bottom of the first panel 21. Limiting grooves 93 are formed on both sides of the arc-shaped groove 91. Limiting sliders 94 are fixed on both sides of the arc-shaped component 92 and slidably disposed in the limiting grooves 93. By sliding the arc-shaped component 92 in the arc-shaped groove 91, the first panel 21 can be flipped on the top of the movable support block 5. At the same time, the limiting sliders 94 slide in the limiting grooves 93 to limit the angle of the first panel 21 flipping and prevent the arc-shaped component 92 from moving out of the arc-shaped groove 91, thereby improving the stability of the first panel 21.

[0038] Preferred, such as Figure 4 As shown:

[0039] The bottom of the movable plate 6 is provided with a first tooth 10, and the side of the fixed seat 4 that is in contact with the movable plate 6 is provided with a second tooth 11 that meshes with the first tooth 10. Through the cooperation of the first tooth 10 and the second tooth 11, the movable plate 6 and the fixed seat 4 can be stably limited, preventing the movable plate 6 and the fixed seat 4 from sliding again, which would cause the first panel 21 to change its flip angle.

[0040] It is worth noting that, such as Figure 5 As shown:

[0041] A traction spring 12 is fixed at the bottom of the inner cavity of the arc groove 91. The movable end of the traction spring 12 is fixedly connected to the end of the arc part 92 away from the first panel 21. The traction spring 12 facilitates the traction of the arc part 92 and restricts the arc part 92 from moving out of the arc groove 91.

[0042] In a further preferred embodiment, such as Figure 2 As shown:

[0043] A baffle plate 13 is fixed to the outer wall of the fixed base 4. The top of the baffle plate 13 is attached to the bottom of the first panel 21 and the second panel 22. The baffle plate 13 can cover the gap between the movable support block 5 and the fixed base 4 to prevent students from accidentally inserting their fingers and causing pinching. At the same time, the first panel 21 and the second panel 22 provide support to maintain the stability of the desktop body 2.

[0044] In addition, such as Figure 1 As shown:

[0045] The top of the second panel 22 is provided with a groove 14, and the top of the first panel 21 is hinged with a book support 15. The groove 14 facilitates the storage of some learning tools that are prone to rolling, preventing them from falling off the desktop body 2. At the same time, the book support 15 can be folded off the first panel 21 to support the books and prevent the books from being unstable on the first panel 21 when it is tilted.

[0046] In this embodiment, as Figure 1-2 As shown:

[0047] Two sets of connecting rods 16 are fixed between the two sets of support legs 1. The table hole frame 3 is located on top of one set of connecting rods 16. The connection rods 16 increase the stability of the two sets of support legs 1 and support the table hole frame 3.

[0048] In practical use, when it is necessary to flip the desktop of the study desk at a certain angle, first loosen the limiting bolts 81 from both sides, then lift the rear of the first panel 21 upwards. At the same time as the first panel 21 is lifted, the first panel 21 drives the support rod 7 to deflect together, and the arc-shaped part 92 slides in the arc-shaped groove 91. Then the arc-shaped part 92 drives the movable support block 5 to slide backwards on the top of the fixed base 4. Then the movable support block 5 drives the movable plate 6 to move backwards together. After the first panel 21 is adjusted to a suitable angle, the student then tightens the limiting bolts 81 from both sides in sequence, so that the movable plate 6 and the fixed base 4 are fixed by the first tooth 10 and the second tooth 11 to complete the angle adjustment of the first panel 21. After adjustment, the structure of the study desk remains stable.

[0049] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
