Detailed Description
In order to more clearly illustrate the technical solutions of the embodiments of the present invention, the drawings used in the description of the embodiments will be briefly described below, and it is obvious that the drawings in the description below are only some embodiments of the present invention, and it is obvious for those skilled in the art that other obvious modifications can be obtained without inventive efforts.
As shown in fig. 1-2, a structural schematic diagram of an electric lifting table includes a table top 1, table legs 5 and a support rod 2, the table legs 5 are equipped with a lifting mechanism, one end of the support rod 2 is hinged on the table top 1, the other end is hinged in the middle of the table legs 5, the upper end of the table legs 5 is movably connected with the table top 1, and the lifting mechanism drives the upper end of the table legs 5 to move along the table top 1.
In fig. 1-2, the lower end of the tabletop 1 is provided with a lifting mechanism, the lifting mechanism comprises a lifting switch 5, a motor 7 and a bidirectional screw nut 9 driven by a rotating shaft of the motor 7 to operate together, two sides of a cross bar 4 are connected with table legs 5, the table legs 5 are connected with a support rod 2, a connecting rod 3 is arranged between the table legs 5, and the lifting mechanism comprises a lifting switch 6 and a motor 7. The supporting rods 2 are arranged at four corners of the bottom surface of the desktop 1 and connected with the desktop 1 through the hinged seats. The number of the cross rods 4 is 2, and the cross rods are parallel to the left table side and the right table side. The number of the motors 7 is two, and synchronous belts 8 are arranged at the rotating shaft positions of the two motors. The two motor rotating shafts are respectively connected with a bidirectional screw rod nut 9, and the cross rod is provided with a notch through which the bidirectional screw rod nut can pass.
In the structure, the cross rod 4 is provided with a notch through which the bidirectional screw rod nut 9 can pass, and the notch is connected with nuts at two ends of the screw rod. When the motor 7 runs, the nuts at the two ends of the screw rod move and drive the cross rod 4 to move along with the nut.
In the structure, a circuit connecting pipeline 10 is arranged between the motor 7 and the lifting switch, and the operation of the motor 7 is controlled by the lifting switch. A synchronous belt 8 is arranged between rotating shafts of the motor 7, and after the switch is pressed down, the motor 7 moves and drives the bidirectional screw rod nut 9 to move synchronously.
