Display supporting device

Abstract

The invention discloses a display supporting device. The display supporting device comprises a circular straight tube and a sliding lifting mechanism mounted in the circular straight tube; the slidinglifting mechanism comprises a coil spring mechanism and at least one sliding member; the sliding members are fixed to the side surface of the coil spring mechanism; the outer sides of the sliding members abut against the inner wall of the circular straight tube; the sliding members slide up and down along the inner wall after being stressed, and predetermined frictional force is formed between the sliding members and the inner wall; the side wall of the circular straight tube is provided with a linear sliding guiding hole; one side of the coil spring mechanism is provided with a protrusion portion; and the protrusion portion extends out of the sliding guiding hole and is used for being connected with a display connecting member and limiting the stroke of the sliding lifting mechanism. Through the closing property of the circular straight tube, the sliding lifting structure in the straight tube is not deformed due to external force, so that the whole lifting process is smoothed while the overall stability is improved.

Description

technical field [0001] The invention relates to the technical field of support devices, in particular to a display support device. Background technique [0002] At present, the lifting support structure of household electronic displays or commercial electronic displays is generally a non-closed open structure, and the lifting structure will use bearings, slide rails or cylinders to realize the lifting function. This kind of non-closed supporting lifting structure, under the action of gravity of the display, the lifting mechanism of the supporting mechanism is stressed along the direction of the opening. Since the supporting structure is not closed, the opening size will become larger after the force is applied and produce bending deformation. As a result, after the product has been used for a period of time, the stability of the supporting structure is poor, and the sliding up and down is not smooth. At the same time, the cost price of bearings, slide rails and cylinders is...

Problems solved by technology

This kind of non-closed supporting lifting structure, under the action of gravity of the display, the lifting mechanism of the supporting mechanism is stressed along the direction of the opening. Since the supporting structure is not closed, the opening size will become larger after the force is applied and produce bending deformation. As a result, after the product has been used for a period of time, the stability of the supporting structure is poor, and the up and down sliding is not smooth, etc.

At the same time, the cost price of bearings, slide rails and cylinders is too high, and the product profit margin is reduced
