Fig. 1 is a schematic structural diagram of the present invention.
Fig. 2 is a circuit diagram of the present invention.
1. The automatic lifting device comprises a plate surface, 2 parts of a plate support, 3 parts of a support, 4 parts of a motor, 5 parts of an operation box, 6 parts of a lead screw, 7 parts of a sliding support rod, 8 parts of a lifting limit switch, 9 parts of a nut, 10 parts of a stop button, 11 parts of a lifting button, 12 parts of a descending button, 13 parts of a descending limit switch and 14 parts of a power supply jack.
Detailed Description
The invention will be further explained with reference to the drawings:
as shown in fig. 1, the lifting publicity board comprises a board surface 1, a board support 2, a lifting device and a support 3, wherein the upper surface of the board support 2 is provided with a board groove, the lower surface of the board support 2 is provided with a slideway, and a layout 1 is fixed on the board support 2; the lifting device comprises a motor 4, an operation box 5, a lead screw 6, a sliding support rod 7 and a nut 9, the nut 9 is fixedly connected with a support 3, the lower end of the lead screw 6 penetrates through the nut 9 and is in threaded connection with the nut 9, a motor 4 rotating shaft is connected to the upper end of the lead screw 6, the operation box 5 is arranged above the motor 4 and is connected with the lower surface of the plate support 2, a motor control loop is arranged in the operation box 5, the front surface of the operation box 5 is an operation panel, a stop button 10, a lifting button 11, a descending button 12 and a power jack 14 are installed on the operation panel, the lower end of the sliding support rod 7 is hinged to the support 3, a round ball is arranged at the upper end of the sliding support rod 7 and slides in a slide way of the support plate 2, and a lifting limit switch 8 and a descending limit switch 13 are installed.
A power supply plug is inserted into a power supply jack 14, when the publicity board needs to be lifted, a lifting button 11 is pressed, a motor 4 rotates in the forward direction, the motor 4 drives a screw rod 6 to rotate, the screw rod 6 drives a board surface 1 to lift under the reaction force of a nut 9, meanwhile, a ball at the upper end of a sliding support rod 7 slides in a sliding groove of a board support 2, the sliding support rod 7 performs corresponding position adjustment, after the board surface 1 is lifted to a required height, a stop button 10 is pressed, the motor 4 stops rotating, and the board surface 1 stops lifting; when the publicity board needs to descend, the descending button 12 is pressed, the motor 4 rotates reversely, the motor 4 drives the lead screw 6 to rotate reversely, the lead screw 6 drives the board surface 1 to descend under the reaction force of the nut 9, meanwhile, the ball at the upper end of the sliding support rod 7 slides in the sliding groove, the sliding support rod 7 performs corresponding position adjustment, the stop button 10 is pressed after the board surface 1 descends to the required height, the motor 4 stops rotating, and the board surface 1 stops descending. When the board surface 1 rises to the highest position, the ball at the upper end of the sliding support rod 7 touches the rising limit switch 8, the rising limit switch 8 is switched off, the motor 4 automatically stops, and the board surface 1 stops rising; when the board surface 1 descends to the lowest position, the ball at the upper end of the sliding support rod 7 touches the descending limit switch 13, the descending limit switch 13 is switched off, the motor 4 automatically stops, and the board surface 1 stops descending.
