Abstract

The invention relates to a multi-stage push cylinder and aims to provide a bush piston type double-stroke push cylinder with output pressure increasing with increase of the number of cylinder sections. The multi-stage push cylinder comprises a plurality of cylinder shafts, a plurality of cylinder barrels, a plurality of pistons, a plurality of partitions, a plurality of air holes, a front cover, a rear cover and the like. The multi-stage push cylinder is divided into a plurality of mutually independent chambers by the partitions. The cylinder shafts and pistons are connected in cascade. A bush piston is disposed inside at least one cylinder barrel and can serve as a pressure piston and also a cylinder barrel for another piston. The cylinder shafts of the multi-stage push cylinder are shortened, so that materials are economized, and types of stored parts are reduced. Pressure of the multi-stage push cylinder can be selected according to actual uses, and the multi-stage push cylinder is reliable to operate, convenient to use and easy to produce.

Description

technical field [0001] The invention relates to the technical field of cylinders, in particular to a multi-stage push cylinder. Background technique [0002] At present, the cylinder on the market is a one-stage cylinder, and the output pressure cannot be adjusted. It is formed by cascading multiple cylinder barrels, with complex structure and large volume. Contents of the invention [0003] The object of the present invention is to provide a piston-piston type double-stroke push cylinder whose output pressure increases as the number of cylinder sections increases. [0004] The invention provides a multi-stage push cylinder, comprising: a cylinder shaft, a mandrel, a connecting shaft, a short shaft, a first piston, a second piston, a third piston, a fourth piston, a first cylinder barrel, and a second cylinder barrel , the third cylinder, steel balls, the first partition, the second partition, the first air hole, the second air hole, the third air hole, the fourth air hol...
