Ceiling lamp with lifting and cable take-up and pay-off functions

Abstract

The invention discloses a ceiling lamp with lifting and cable take-up and pay-off functions. A clamping device is fixedly connected with the upper part of a lampshade; an expansion rod is arranged above the clamping device; a through hole is formed in the middle of each of the lampshade and the clamping device; a mounting plate is fixedly connected with the top of a loop bar; a circular hole is formed in each of four corners at the upper part of the mounting plate; a fixed bolt penetrates through the circular hole; the fixed bolt is fixedly connected with the top wall of a wall body through threads; a piston rod is arranged on the left side of the expansion rod; an air cylinder is glidingly connected with the upper part of the piston rod in a sealed manner; the mounting plate is fixedly connected with the upper end of the air cylinder; and the lower end of the piston rod is fixedly connected with the lower end of the expansion rod through a synchronizing rod. The ceiling lamp has the advantages that the lower end of the expansion rod is fixedly connected with the lampshade through the clamping device, the lampshade is convenient to dismount to change and maintain a bulb, the pistonrod is driven through pressure change in the air cylinder to expand longitudinally to further drive the synchronizing rod and the expansion rod to synchronically realize a longitudinal adjustment function, and a rotating cable take-up roll rotates to perform cable take-up and pay-off while the expansion rod performs height adjustment.
