Abstract

The invention provides a lamp and a lifting device for the same. The lifting device is characterized by comprising a sleeve, a plurality of balls, a guide tube, a spring, an end cover and a hanger rod, wherein the guide tube is pressed towards a second port to move towards the second port, the balls move towards the inner sidewall of the sleeve to be scattered, and the hanger rod can move in an extension direction of the guide tube; when the guide tube is not pressed towards the second port, the guide tube is driven by the spring to move towards a first port, the balls move away from inner sidewall of the sleeve to be gathered under the extrusion of the inner sidewall of the sleeve, and the hanger rod is fixed by the gathering and extrusion of the balls.

Description

technical field [0001] The invention relates to the field of lamp design. Background technique [0002] The heights of commonly used hanging lamps are mostly non-adjustable, and the products have a fixed hanging height after manufacture. Some suspended lamps use an auxiliary remote control device to adjust the height of the suspended lamp, but this method has a complicated structure and high cost. Contents of the invention [0003] The invention provides a lifting device, which is characterized in that it comprises: a sleeve, the inner wall of the sleeve is conical and provided with a first open end and a second open end, wherein the first open end is smaller than the The second opening end; a plurality of balls; a guide cylinder, the extension direction of the guide cylinder is provided with a first through hole, and the outer wall of the guide cylinder is provided with a plurality of through holes for the balls to be placed, each The through hole is adapted to one of t...
