[0031] like Figure 1-7 As shown, the embodiment of the present application discloses an easy-to-adjust preschool education table, including a table top 10, a table leg assembly 20, and a control assembly 30. Two table leg assemblies 20 are arranged at intervals at the bottom of the table top 10. The two table leg assemblies 20 are controlled to extend and retract through a control assembly 30, so that the table top 10 can be raised and lowered. The operation is simple and convenient, and it ensures that the table top 10 always remains level.

[0032] Specifically, two table leg assemblies 20 are arranged on both sides of the table top 10 in the length direction. The table leg assembly 20 includes a base plate 21, which is used to contact the bottom surface. The length direction of the base plate 21 is perpendicular to the length direction of the table top 10. A first support tube 22 and a second support tube 23 are arranged on the base plate 21 at intervals along the length direction of the base plate 21. A support rod 24 is slidably arranged in the first support tube 22, so that the support rod 24 can slide along the first support tube 22. The top of the support rod 24 is connected to the table top 10, so that the support rod 24 and the table top 10 are raised and lowered synchronously. A threaded rod 25 is spirally arranged in the second support tube 23, so that when the threaded rod 25 is driven to rotate, the threaded rod 25 is raised and lowered along the second support tube 23. The top of the threaded rod 25 is rotatably mounted on the bottom surface of the table top 10. A first pulley 26 is mounted on the upper side of the threaded rod 25. A rotating shaft 27 is rotatably mounted on the bottom surface of the table top 10. A second pulley 271 and a driven pulley 272 are coaxially mounted on the rotating shaft 27. The second pulley 271 is connected to the first pulley 26 via a transmission belt 28, so that when the second pulley 271 rotates, the threaded rod 25 rotates. A rotating shaft 11 is rotatably mounted on the bottom surface of the table top 10. A driving pulley 12 is mounted on the rotating shaft 11. The driving pulley 12 engages with the two driven pulleys 272, so that when the driving pulley 12 rotates, the two driven pulleys 272 rotate, thereby driving the threaded rods 25 of the two leg assemblies 20 to rotate synchronously. Several connecting columns 13 are mounted on the bottom of the several connecting columns 13. A mounting plate 14 is mounted parallel to the table top 10. A control assembly 30 for controlling the rotation of the rotating shaft 11 is mounted on the mounting plate 14.

[0033] During setup, the mounting plate 14 has a circular opening extending through it. The control assembly 30 includes a turntable 31 that rotates within the circular opening. The turntable 31 is coaxially arranged and fixedly connected to the rotating shaft 11, so that rotation of the turntable 31 drives the rotating shaft 11. The circular opening is located near the edge of the mounting plate 14 to facilitate control of the turntable 31. A crank 32 is provided on the turntable 31 to facilitate rotation. Specifically, a receiving slot 33 is provided on the side of the turntable 31 facing away from the tabletop 10. A horizontally arranged hinge shaft 34 is disposed within the receiving slot 33. The length of the hinge shaft 34 is perpendicular to the length of the receiving slot 33. The crank 32 is hingedly connected to the turntable 31 via the hinge shaft 34, allowing it to rotate about the hinge shaft 34. When not in use, the crank 32 is retracted into the receiving slot 33 to prevent the protruding crank 32 from causing any bumps or collisions with children. A first magnet 35 is disposed at the bottom of the receiving slot 33, and a second magnet 36 is disposed on the crank handle 32 corresponding to the first magnet 35. After the crank handle 32 is rotated into the receiving slot 33, the first magnet 35 and the second magnet 36 attract each other, securing the crank handle 32. The end of the crank handle 32 away from the hinge axis 34 is spaced a certain distance from the adjacent and opposing wall of the receiving slot 33, making it easier for a person to remove the crank handle 32 from the receiving slot 33.

[0034] The turntable 31 is also provided with a fixing unit 40 for fixing the turntable 31 to the mounting plate 14. The fixing unit 40 includes a circular ring 41 provided on the turntable 31. A plurality of through holes 42 are circumferentially spaced apart on the circular ring 41. Screw holes 43 are provided on the table top 10. Screws are screwed into the screw holes 43 through the through holes 42 to fix the circular ring 41. A circular hole 44 is provided on the surface of the circular ring 41 away from the table top 10, corresponding to the through hole 42. The diameter of the circular hole 44 is larger than the diameter of the through hole 42, and the depth of the circular hole 44 is smaller than the depth of the through hole 42. When selecting a screw, a screw with a head thickness less than the depth of the circular hole 44 is selected. When the bolt is screwed into the screw hole 43, the head of the bolt is located in the circular hole 44, preventing the bolt head from extending too long and causing a bump to a child.

[0035] The four corners of the table top 10 and the mounting plate 14 are all rounded to prevent the corners of the table top 10 and the mounting plate 14 from bumping against young children. A panel 15 is provided between the edge of the lower surface of the table top 10 and the edge of the upper surface of the mounting plate 14 to shield the mechanism between the table top 10 and the mounting plate 14 to ensure aesthetics. An opening is provided on one side of the panel 15, and a drawer is slidably provided on the mounting plate 14 at the opening to avoid wasting excess space between the table top 10 and the mounting plate 14. In the specific setting, a threaded hole can be horizontally opened on the upper side of the first support tube 22, and a bolt can be screwed into the threaded hole. The bolt is screwed so that the end of the bolt abuts against the support rod 24, thereby fixing the support rod 24 and further ensuring the stability of the table top 10.

[0036] The operating principle of the easily adjustable preschool education table in this embodiment is as follows: when the height of the table top 10 needs to be adjusted, the crank handle 32 is first buckled out of the receiving groove 33, and then the crank handle 32 is rotated to rotate the disk, the rotating shaft 11, and the driving wheel 12, thereby driving the rotating shaft 11 and the second pulley 271 to rotate. Since the second pulley 271 is connected to the first pulley 26 by the transmission belt 28, the rotation of the second pulley 271 drives the first pulley 26 and the threaded rod 25 to rotate. Since the second support tube 23 is in a fixed state, the threaded rod 25 moves up and down in the second support tube 23, adjusting the table top 10 to the appropriate height. Then, the crank handle 32 is rotated back into the receiving groove 33, and the first magnet 35 and the second magnet 36 attract each other, fixing the crank handle 32. Then, a screw is screwed through the through hole 42 into the screw hole 43 to fix the ring 41, thereby fixing the turntable 31 and the table leg assembly 20. The control component 30 controls the lifting of the table leg components 20 on both sides at the same time, thereby controlling the lifting of the table top 10. The operation is simple and convenient, and ensures that the table top 10 always remains level.
