The present invention relates to a lightweight, high-rigidity multi-section cylindrical vacuum bottle and a preparation method thereof, designed to address the technical problems of existing similar products such as difficulty in reusing the outer casing, poor environmental performance, high packaging cost, and room for improvement in material production processes. The key point is that the outer diameter of the large ring of the vacuum bottle is provided with an alumina pump sleeve corresponding to the shape of the large ring. The lower outer wall of the outer sleeve of the large ring is provided with equidistantly distributed anti-rotation ribs, and the upper outer wall of the outer sleeve of the large ring between the anti-rotation ribs is provided with glue storage grooves. The glue storage grooves at the stepped positions are provided with through holes. The upper outer wall of the outer sleeve of the alumina pump sleeve is provided with stamped fastening ribs. The inner diameter of the mouth of the outer cover is fastened and fixed to the fastening ribs of the alumina pump sleeve through arc-shaped ribs. The inner diameter at the fastening ribs of the alumina pump sleeve is a dispensing ring. The anti-rotation ribs of the large ring correspond to the inner wall ribs of the alumina pump sleeve. The top sleeve opening of the alumina pump sleeve is provided with an inward flange, which fastens the top ring opening of the large ring.
