The two limiting rods 15 are located between the rectangular bar 18 and the fixed block 14 and are sleeved with a second spring 17. The top of the rectangular bar 18 is fixedly connected to one end of the fixed block 14 with a rack 19, and the bottom of the rotating plate 4 is fixedly connected to one side of the rack 19 with a missing gear 20, and the missing gear 20 is adapted to the rack 19, and the missing gear 20 is colinear with the rotation axis of the rotating plate 4. The limiting mechanism also includes a strip hole opened at one end of the rectangular bar 18 away from the fixed block 14, and a square rod 23 is slidably sleeved at one end of the rectangular bar 18 away from the fixed block 14, and the square rod 23 slides through The rectangular bar 18 is provided with a square hole adapted to the square rod 23. The square rod 23 is fixedly connected to a push plate 22 at one end of the strip hole, and a third spring 21 is fixedly connected to the other side of the push plate 22, and the other end of the third spring 21 is fixedly connected to the other end of the strip hole. The other end of the square rod 23 is fixedly connected to an inclined block 24. Through the setting of the limiting mechanism, the panel 704 will not be unstable due to the use of the teacher after it rises. The lecture table body 1 is located at the bottom inner side of the desktop 101 near the enclosure 2 and is rotatably connected to the rotating bar 10 through a bearing. Both sides of the top of the rotating bar 10 are fixedly connected to electric push rods 11. The bottom of the rotating plate 4 is fixedly connected to one side of the enclosure 2 with two vertical plates 12, and the bottoms of the two vertical plates 12 are rotatably connected to rotating blocks 13.The two rotating blocks 13 are fixedly connected to the top of the adjacent electric push rods 11, and the two electric push rods 11 are used to realize the unfolding and storage of the rotating plate 4.

[0021] In this embodiment, an L-shaped baffle 5 is fixedly connected to the bottom of the desktop 101, and storage drawers 3 are slidably mounted on both sides of the L-shaped baffle 5. Square holes matching the storage drawers 3 are opened on both sides of the L-shaped baffle 5. The storage drawers 3 are arranged to facilitate the storage of the teacher's teaching tools and lamps. A host cabinet is arranged on the inner side of the bottom of the desk body 1, which can be used to place the host and is provided with a cabinet door.

[0022] Working principle: A smart teaching table for a smart classroom. When the computer is not used, the rotating plate 4 is flush with the desktop 101 and can be used normally. The storage drawers 3 on both sides can be used by teachers to store teaching materials and other teaching tools. When the computer is needed, the two electric push rods 11 are started synchronously to extend the electric push rods 11. At this time, the rotating block 13 and the vertical plate 12 are used to gradually expand the rotating plate 4. After the rotating plate 4 is expanded by ninety degrees, the blocking rod 9 is separated from the lifting plate 703. Under the action of the first spring 702, the lifting plate 703 is raised until the panel 704 is flush with the desktop 101. At the same time, when the rotating plate 4 rotates, the missing gear 20 drives the rack 19 to move, so that the rectangular bar 18 brings the inclined block 24 to approach the lifting plate 703. As the rotating plate 4 rotates, until the missing gear 20 is separated from the rack 19, the rectangular bar 18 moves to the maximum distance. At this time, when the lifting plate 703 rises, when the lifting plate 703 is close to the inclined block 24, it pushes When the lifting plate 703 is lifted up to the top of the inclined block 24, the inclined block 24 is reset under the action of the third spring 21, so as to limit the lifting plate 703. When the teacher uses the keyboard 8 and the mouse, the lifting plate 703 and the panel 704 will not drop to the bottom of the desktop 101, and the panel 704 is always kept flush with the desktop 101. At the same time, when the rotating plate 4 rotates more than ninety degrees, the two electric push rods 11 can be controlled to control the angle of the rotating plate 4, so that it is convenient for the teacher to use. When the rotating plate 4 and the computer display screen 6 need to be stored, the two electric push rods 11 are started to retract, so that the rotating plate 4 is gradually reset. Due to the lack of gear 20 between the baffle rod 9 and the lifting plate 703, it first contacts with the rack 19, so that the rectangular bar 18 is reset with the inclined block 24. At this time, when the baffle rod 9 contacts the lifting plate 703, the lifting plate 703 and the panel 704 are pressed downward until they are reset to the original state.
