High-precision compact double-slide-rail integrated I-shaped structure continuous zooming mechanism

The invention discloses a high-precision compact double-slide-rail integrated H-shaped structure continuous zooming mechanism, which comprises a lens barrel and a zoom lens, the lens barrel comprises annular pieces arranged on the two sides of the lens barrel and two groups of slide rails connected between the two annular pieces, the two side walls of the two groups of slide rails are movably connected with slide plates, and the slide plates are movably connected with the zoom lens. A lens supporting frame is connected between the two sliding plates, the zoom lens is installed in the lens supporting frame, and rollers are further connected to the lens barrel and matched with the sliding plates. Compared with the prior art, the high-precision double-slide-rail varifocal optical lens transmission mechanism provided by the invention has the advantages that the transmission of the varifocal optical lens is more stable, the transmission precision is high, the varifocal optical lens transmission mechanism can adapt
