[0002] A multifunctional desk is a desk that is designed to integrate multiple functions and can adapt to different learning and work needs. This type of desk goes beyond the traditional single purpose of learning or writing, and through innovative design, it increases flexibility, convenience and practicality.

[0003] Existing multifunctional desks for students are usually provided with a rotating desktop for placing drawing paper for drawing. However, the current rotating desktop cannot be expanded. When the drawing paper is large, it tends to occupy a large area, which is not convenient for placing works that need to be referenced. It is not convenient to use and is relatively inconvenient.

[0004] Therefore, it is necessary to design a multifunctional desk for students that can quickly expand the rotating desktop, place drawing papers of different sizes, and place reference works on the expanded desktop to improve the practicality of the device. Utility Model Content

[0005] In order to overcome the shortcomings of existing multifunctional desks for students, the current rotating desktop cannot be expanded, it is easy to occupy a large area when the drawing paper is large, it is not convenient to place the works that need to be referenced, it is not convenient to use, and it is relatively inconvenient, the utility model provides a multifunctional desk for students that can quickly expand the rotating desktop, which is convenient for placing drawing papers of different sizes and can conveniently place reference works on the expanded desktop, thereby improving the practicality of the device.

[0006] The technical solution of the utility model is: a multifunctional desk for students, including supporting feet, a storage box, a first supporting frame, a rotating table top, a second supporting frame and a rotating shaft, the upper and middle parts of the supporting feet are connected to the storage box, the supporting feet are connected to the first supporting frame, the first supporting frame is connected to the storage box, the rear part of the first supporting frame is rotatably connected to the rotating shaft, the rotating table top is connected to the rotating shaft, the lower part of the rotating table top is rotatably connected to the second supporting frame, and the second supporting frame is clamped with the first supporting frame.

[0007] Preferably, two front and rear anti-slip pads are provided on the lower sides of the left and right parts of the support frame.

[0008] Preferably, a placement plate is rotatably provided on the rotating table top.

[0009] As a preferred embodiment, an extended desktop is also included, and both left and right parts of the rotating desktop are rotatably connected to the extended desktop.

[0010] Preferably, it also includes a connecting block, a sliding frame, a limiting frame, a guide rod and a telescopic spring. The lower part of the rotating desktop is rotatably connected to the left and right connecting blocks, the outer parts of the connecting blocks are rotatably connected to the sliding frames, the sliding frames are slidably connected to the adjacent extended desktops, the sliding frames are connected to the guide rods, the front and rear parts of the guide rods are slidably connected to the limiting frames, the limiting frames are clamped with the adjacent extended desktops, and the limiting frames are connected to the sliding frames with telescopic springs.

[0011] Preferably, the limiting frames are all L-shaped.

[0012] The beneficial effect of the utility model is that the utility model rotates the expansion desktop upward, drives the sliding frame to move inward, drives the connecting block to rotate, and when the expansion desktop is flush with the rotating desktop, drives the limiting frame to move outward, so that the limiting frame and the expansion desktop are snapped together, so that the rotating desktop can be quickly expanded, it is convenient to place drawing papers of different sizes, and it is convenient to place reference works on the expansion desktop, thereby improving the practicality of the device.

DETAILED DESCRIPTION

[0018] The utility model is further described below in conjunction with the accompanying drawings and specific implementation methods.

[0019] A multifunctional desk for students, such as Figure 1-Figure 4As shown, it includes a support leg 1, a storage box 2, a first support frame 3, a rotating desktop 4, a second support frame 5, a rotating shaft 6, an expansion desktop 7, a connecting block 8, a sliding frame 9, a limiting frame 10, a guide rod 11 and a telescopic spring 12. The lower sides of the left and right parts of the support frame are provided with two front and rear anti-skid pads for anti-skid. The upper and middle parts of the support leg 1 are connected to the storage box 2, the support leg 1 is connected to the first support frame 3, the first support frame 3 is connected to the storage box 2, the rear of the first support frame 3 is rotatably connected to the rotating shaft 6, the rotating desktop 4 is connected to the rotating shaft 6, the rotating desktop 4 is rotatably provided with a placement plate for placing items, and the lower part of the rotating desktop 4 A second support frame 5 is rotatably connected, and the second support frame 5 is clamped with the first support frame 3. The left and right parts of the rotating desktop 4 are rotatably connected with the extended desktop 7. The lower part of the rotating desktop 4 is rotatably connected with two left and right connecting blocks 8. The outside of the connecting blocks 8 are rotatably connected with sliding frames 9. The sliding frames 9 are slidably connected to the adjacent extended desktops 7. The sliding frames 9 are connected with guide rods 11. The front and rear parts of the guide rods 11 are slidably connected with limiting frames 10. The limiting frames 10 are all L-shaped for easy clamping. The limiting frames 10 are clamped with the adjacent extended desktops 7. A telescopic spring 12 is connected between the limiting frames 10 and the sliding frames 9.

[0020] At this time, the telescopic spring 12 is in a contracted state. When using the device, first place the supporting foot 1 on the ground, then place the books in the storage box 2, and use the anti-skid pad to prevent slipping. When you need to paint, you can rotate the rotating table top 4 to drive the rotating shaft 6 to rotate on the first supporting frame 3, and then rotate the second supporting frame 5 downward so that the second supporting frame 5 is engaged with the first supporting frame 3 to support the rotating table top 4. Then, rotate the expansion table top 7 upward to drive the sliding frame 9 to move inward and drive the connecting block 8 to rotate. When the expansion table top 7 is flush with the rotating table top 4, the telescopic spring 12 is restored to drive the limiting frame 10 to move outward so that the limiting frame 10 is engaged with the expansion table top 7 to engage the sliding frame 9. The second support frame 5 is rotated so that the second support frame 5 is no longer engaged with the first support frame 3, and then the rotating table top 4 is rotated downward to drive the rotating shaft 6 to rotate, so as to level the rotating table top 4, and then the limiting frame 10 is moved inward, the telescopic spring 12 is squeezed and contracted, and then the extended table top 7 is rotated downward to make the sliding frame 9 move outward, so that the connecting block 8 is rotated to store the extended table top 7.

[0021] The above description is only an example of the implementation of the present invention and is not intended to limit the present invention. Any equivalent replacement made within the principle of the present invention shall be included in the protection scope of the present invention. The contents not elaborated in the present invention belong to the existing technology known to the technicians in this professional field.
