Detailed Description

The present invention will be further described with reference to the accompanying drawings and the following detailed description.

Example (b):

referring to fig. 1 and 2, the electric lifting lamp pole of the present embodiment includes a fixing rod 2, a lifting rod 9 inserted and assembled in an inner cavity of the fixing rod 2, and a lifting driving mechanism for driving the lifting rod 9 to move up and down in the inner cavity of the fixing rod 2. The dead lever 2 is 258mm x 4000 mm's square tube, and its bottom mounting has ring flange 1, ring flange 1 is 500mm x 500 mm's square ring flange to evenly be provided with 4 bolt mounting holes 16. The lifting rod 9 is a square tube with the size of 200mm multiplied by 3000 mm.

The lifting driving mechanism comprises a motor 15, a lead screw 6 and a lifting guide rail 10. And a lifting driving mechanism bracket 3 is fixed on the inner wall of the lower end of the fixed rod 2. The motor 15 is a speed reducing motor, is arranged in the inner cavity at the lower end of the fixing rod 2 and is fixedly arranged on the lifting driving mechanism bracket 3.

The lifting guide rail 10 is a U-shaped channel steel and is inserted into the inner cavity of the lifting rod 9, the bottom end of the U-shaped channel steel is fixed on the top surface of the lifting driving mechanism support 3, the top end of the U-shaped channel steel is fixed with a lead screw fixing seat 8, and the lower end of the U-shaped channel steel is fixed with a lead screw supporting seat 4. The lead screw 6 is positioned in the lifting guide rail 10, the top end of the lead screw is assembled on a lead screw fixing seat 8 at the top end of the lifting guide rail 10 through a bearing, the lower end of the lead screw is assembled in a lead screw supporting seat 4 through a bearing, and the bottom end of the lead screw is in transmission connection with a main shaft of a motor 15 through a coupler 14. A screw nut 13 is assembled on the screw 6 in a threaded manner, as shown in fig. 2, a hinge shaft 12 is fixed on one side of the screw nut 13, and the other side of the screw nut is clamped in the lifting guide rail 10; two symmetrical hinge seats 11 are fixed on the inner wall of the bottom port of the lifting rod 9, and two ends of the hinge shaft 12 are respectively hinged with the hinge seats 11.
