Because the universal wheels are extended to move the device when the height of the desktop is lowered, The invention discloses a technical means, so when the height of the desktop is lowered to the lowest, the bottom of the connecting plate will contact the top of the supporting foot, and the wheel of the universal wheel will be fully extended at this time, so that the device can be pushed to move, and it is driven by a motor, so that it is more labor-saving when adjusting the height of the desktop. It effectively solves the problem that most of the existing technologies for adjusting the height of the home student desks proposed in the background technology are very labor-intensive and troublesome to adjust, and most of the home student desks in the existing technology are large in size and weight, and are very inconvenient to move. It requires multiple people to lift and move the student desk, which is troublesome and laborious. Therefore, it realizes the technical effect of easy operation, easy adjustment of the height of the desktop of the student desk, easy movement of the student desk, saving time and labor.
[0023] In this embodiment, the tops of both ends of the two supporting legs 6 are fixedly connected with the first protective box 10, and the two first protective boxes 10 on the same side are provided with a second slide groove 11 on the side close to each other, and the universal wheel 8 is arranged in the first protective box 10, and the second slide groove 11 is adapted to the connecting plate 7, and the connecting plate 7 is slidably connected to the first protective box 10.
[0024] In this embodiment, both ends of the connecting plate 7 are penetrated by limiting rods 12, the bottom of the limiting rods 12 is fixedly connected to the supporting foot 6, and the tops of both ends of the supporting foot 6 are respectively fixedly connected to the second protection box 13 and the third protection box 14.
[0025] In this embodiment, the two supporting legs 6 are fixedly connected to the same base plate 20 on the side close to each other, the top of the base plate 20 is fixedly connected to the fourth protective box 15, and the top of the fourth protective box 15 is fixedly connected to the fifth protective box 16.
[0026] In this embodiment, a motor 17 is disposed inside the fourth protective box 15 . The motor 17 is fixedly connected to the fourth protective box 15 . A screw rod 18 is fixedly connected to the output shaft of the motor 17 . The screw rod 18 is sleeved with a sleeve 19 .
[0027] In this embodiment, the top of the sleeve 19 is fixedly connected to the bottom of the table box 2, the motor 17 is electrically connected to the motor driver, the motor driver is electrically connected to the PLC control panel 21, and the PLC control panel 21 is installed on one of the second supporting legs 4.
[0028] Working principle: When using this device, if it is necessary to adjust the height of the desktop 1, the motor 17 can be started through the PLC control panel 21, and the output shaft of the motor 17 will drive the screw rod 18 to rotate, and the rotation of the screw rod 18 will drive the sleeve 19 to rise, and the rising of the sleeve 19 will drive the table box 2 to rise, and the rising of the table box 2 will drive the desktop 1 to rise, so as to increase the height of the desktop 1 to adapt to users with taller heights. When the desktop 1 rises, it will drive the first supporting leg 3 to rise. Through the cooperation of the first supporting leg 3 and the second supporting leg 4, the stability of the desktop 1 can be guaranteed and the desktop 1 will not deviate when it rises or falls. If it is necessary to lower the height of the desktop 1, the output shaft of the motor 17 can be reversed to lower the height of the desktop 1 to adapt to users with shorter heights. When it is necessary to move this device, the output shaft of the motor 17 can be continuously rotated in the opposite direction. When the bottom of the first supporting leg 3 contacts the connecting plate 7, the output shaft of the motor 17 can be continuously reversed, so that the bottom plate 20 can be relative to the connecting plate 7. When the connecting plate 7 rises, the bottom plate 20 will drive the supporting foot 6 to rise relative to the connecting plate 7, the supporting foot 6 will leave the ground, and the universal wheel 8 will move out of the slot 9. As the supporting foot 6 rises relative to the connecting plate 7, the first supporting leg 3, the second supporting leg 4, the table box 2, and the table top 1 will all rise relative to the connecting plate 7, causing the output shaft of the motor 17 to continue to reverse until the bottom of the connecting plate 7 contacts the top of the supporting foot 6. When the connecting plate 7 moves, the limit rod 12 is used to limit the connection plate 7 to ensure the stability of the connecting plate 7 during movement, so that the connecting plate 7 will not deviate during movement. After the bottom of the connecting plate 7 contacts the top of the supporting foot 6, the device will be completely raised, and the wheel part of the universal wheel 8 will be completely moved out of the slot 9, so that the device can be pushed to move the device to other positions. After the device is moved to a suitable position, the PLC control panel 21 is used to make the output shaft of the motor 17 rotate forward to retract the universal wheel 8, so that the bottom of the supporting foot 6 can contact the ground again.
