This is merely for the convenience of description and does not indicate or imply that the device or element must have a specific orientation, be constructed and operated in a specific orientation. Therefore, it cannot be understood as a limitation on the present invention.

[0035] In addition, it should be noted that in the description of the present invention, unless otherwise clearly specified and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For those skilled in the art, the specific meanings of the above terms in the present invention can be understood according to the specific circumstances.

[0036] like Figure 1-Figure 8 As shown, this embodiment proposes a multifunctional desk for displaying works, including telescopic legs 3 and supporting legs 1, the supporting legs 1 are approximately in an "L" shape, and acute angles are formed between the supporting legs 1, thereby improving the overall supporting effect, and this method can provide students with a larger activity space, effectively reduce the overall floor space, and facilitate placement.

[0037] A rubber pad 2 is connected to the lower surface of the supporting leg 1. On the one hand, the rubber pad 2 increases the friction and effectively reduces the horizontal movement of the supporting leg 1, thereby facilitating the use of the students. On the other hand, the setting of the rubber pad 2 can protect the ground when the supporting leg 1 is placed on the ground, which can effectively reduce the occurrence of ground damage caused by excessive overall weight.

[0038] A cavity is opened at the upper end of the supporting leg 1, and a slide rail is arranged in the cavity. The lower end of the telescopic leg 3 is located in the cavity and is slidably connected to the slide rail. The setting of the slide rail facilitates the sliding of the telescopic leg 3, and at the same time plays a guiding and limiting role for the sliding of the telescopic leg 3, thereby reducing the shaking of the telescopic leg 3.

[0039] The support leg 1 is threadedly connected with a plurality of bolts 17, which penetrate the outer wall of the support leg 1 and then enter the cavity, and then the bolts 17 can abut on the telescopic leg 3. The telescopic leg 3 is provided with a plurality of lifting grooves 18 that can accommodate the bolts 17. When the bolts 17 are screwed into the lifting grooves 18, the telescopic leg 3 can be limited at this time, and the relative locking work between the telescopic leg 3 and the support leg 1 can be realized.

[0040] The telescopic legs 3 are rotatably connected to a table top 8 and a support arm 7. There are two support arms 7, and the support walls 7 are located on both sides of the table top 8. The table top 8 and the support arm 7 can rotate independently, and the support arm 7 can rotate simultaneously with the table top 8.

[0041] The table top 8 can be in a horizontal state for daily use, the table top 8 can be rotated to an inclined state, in which case it can be used for students to take a nap, and the table top 8 can be rotated to a vertical state, in which case it can be used as a drawing board. It can have multiple functions at the same time, is suitable for use in different scenarios, and is highly practical.

[0042] The end of the support arm 7 away from the telescopic leg 3 is rotatably connected to the support sleeve 9. When an angle is formed between the table board 8 and the support arm 7, the support sleeve 9 can abut against the lower surface of the table board 8, and the support sleeve 9, the table board 8 and the support arm 7 form a triangular stable structure. The support arm 7 can cooperate with the table board 8 to support the table board 8, thereby effectively increasing the stability of the table board 8 in an inclined state, so as to facilitate students to take a nap.

[0043] The telescopic leg 3 is rotatably connected to a rotating shaft 4, which is fixedly connected to a supporting arm 7 and can rotate around the rotating shaft 4. The telescopic leg 3 is rotatably connected to a main shaft, which is fixedly connected to a table top 8 and can rotate around the main shaft. The rotating shaft 4 and the main shaft are independently arranged and their rotation does not interfere with each other.

[0044] One end of the support arm 7 close to the telescopic leg 3 is fixedly connected to the limit block 20. When the limit block 20 abuts against the telescopic leg 3, the support arm 7 is in a horizontal state. Due to the setting of the limit block 20, when the support arm 7 is in a horizontal state, since the limit block 20 has been in contact with the telescopic leg 3, the support arm 7 cannot continue to rotate downward, thereby supporting the table top 8.

[0045] The support arm 7 protrudes inward to form a clamping portion 22. When the table top 8 is in a horizontal state, the support arm 7 is in a horizontal state and supports the table top 8. The clamping portion 22 can support the lower surface of the table top 8. At this time, the clamping portion 22 and the lower surface of the table top 8 are in contact. Due to the limitation of the limit block 20, the support arm 7 cannot continue to rotate downward. Therefore, auxiliary support for the table top 8 can be achieved, so that the table top 8 can remain in a horizontal state, which is convenient for daily use.

[0046] The support sleeve 9 is threadedly connected with a screw rod 10, and a plurality of slots 11 are provided on the lower surface of the table top 8. The upper end of the screw rod 10 can be inserted into the slot 11. The length of the screw rod 10 screwed out of the support sleeve 9 can be adjusted according to the angle of the table top 8, so that the screw rod 10 can be inserted into the corresponding slot 11 to support the table top 8.

[0047] The main shaft is fixedly connected to a worm wheel 19, and the telescopic leg 3 is rotatably connected to a worm 5, and the worm 5 and the worm wheel 19 are meshed; the worm 5 is fixedly connected to a knob 6, and the upper end of the knob 6 passes through the telescopic leg 3. The worm 5 can be driven to rotate by the set knob 6, and the worm 5 can drive the table top 8 to rotate through the worm wheel 19. The self-locking property of the worm wheel and worm can realize self-locking of the table top 8 after rotation.

[0048] An iron sheet 21 is connected to one end of the support arm 7 away from the telescopic leg 3, and a magnet 12 that attracts the iron sheet 21 is connected to the lower surface of the table top 8. By setting the magnet 12 and the iron sheet 21, when the table top 8 rotates, the support arm 7 can be driven to rotate at the same time.

[0049] When the support arm 7 rotates with the table top 8, a gap for clamping is formed between the clamping portion 22 and the lower surface of the table top 8. At the same time, due to the limitation of the magnet 12, the gap can support both sides of the drawing paper. In order to facilitate clamping, the lower surface of the table top 8 and the upper surface of the clamping portion 22 can be provided with corresponding clamping pads. The clamping pads can increase the friction during clamping and improve the clamping effect.

[0050] A slide groove 14 is provided on the lower surface of the table top 8, and a fixing rod 15 is fixedly connected in the slide groove 14. The slide groove 14 also includes a pressing plate 16 which is sleeved on the fixing rod 15 and can slide and rotate on the fixing rod 15. The pressing plate 16 has a sliding hole, and the fixing rod 15 is inserted into the sliding hole. The pressing plate 16 can freely rotate or slide on the fixing rod 15, so as to facilitate clamping of different positions of drawing paper or display works.

[0051] A magnetic strip 13 that can attract the pressure plate 16 is arranged on one side of the slide groove 14. Several pressure plates 16 are arranged. In order to better facilitate the setting of the pressure plate 16, the fixing rod 15 can also be detachably connected to the slide groove 14, and the bolt connection between the fixing rod 15 and the slide groove 14 can be achieved by bolts. Different numbers of pressure plates 16 can be set according to actual needs.

[0052] The pressing plate 16 can be attracted to the magnetic strip 13, and the drawing paper can be clamped at this time. At the same time, the iron sheet 21 on the support arm 7 and the magnet 12 on the lower side of the table top 8 are attracted to each other. At this time, a gap for clamping the drawing paper or displaying the works on both sides is formed between the clamping portion 22 and the lower surface of the table top 8. Through the above arrangement, the side edges of the drawing paper or the work paper can be clamped, thereby effectively improving the fixing effect of the drawing paper and the display works without taking up too much space.

[0053] The specific working process is as follows: during daily use, the table top 8 is set horizontally, and the support arm 7 is set horizontally at the same time. At this time, the limit block 20 is in contact with the telescopic leg 3, and the support arm 7 cannot continue to rotate downward. The lower surface of the table top 8 is in contact with the upper surface of the clamping part 22. At this time, the support arm 7 realizes auxiliary support for the table top 8.

[0054] When students need to take a nap, they can rotate the knob 6, which drives the worm 5 to rotate, which drives the worm wheel 19 to rotate, and the worm wheel 19 drives the table board 8 to rotate, so as to set the tilt direction of the table board 8. Then, they can rotate the support sleeve 9 to keep the support sleeve 9 at a suitable angle, and screw the screw 10 outwards to make the screw 10 snap into the slot 11 on the lower surface of the table board 8. The support sleeve 9, the table board 8 and the support arm 7 form a triangular stable structure. The support arm 7 can cooperate with the table board 8 to support the table board 8, thereby effectively increasing the stability of the tilted state of the table board 8, making it convenient for students to take a nap.

[0055] When it is needed to be used as a drawing board or a work display board, the knob 6 is rotated, the knob 6 drives the worm 5 to rotate, the worm 5 drives the worm wheel 19 to rotate, the worm wheel 19 drives the table top 8 to rotate, and the table top 8 drives the support arm 7 to rotate at the same time through the magnet 12, so that the table top 8 is rotated to a vertical state, and the pressure plate 16 and the support arm 7 are rotated. The pressure plate 16 and the magnetic strip 13 cooperate to fix the upper end of the drawing paper or the display work, and the clamping part 22 and the lower surface of the table top 8 cooperate to fix the two sides of the drawing paper or the display work.

[0056] When the height of the table top 8 needs to be adjusted, the bolt 17 is loosened and the bolt 17 is screwed out of the lifting slot 18. At this time, the telescopic leg 3 can slide relative to the supporting leg 1 to adjust the height of the table top 8. After the adjustment is completed, the bolt 17 is tightened and screwed into the lifting slot 18 to achieve relative locking between the telescopic leg 3 and the supporting leg 1, thereby fixing the height of the table top 8.
