Abstract
The utility model belongs to the improvement of a hydraulic oil cylinder. The improvement of a hydraulic oil cylinder aims at improving a hydraulic oil cylinder into a multi-cavity oil cylinder. The structural size of the hydraulic oil cylinder in a circumference direction can not be increased under the working condition that pressure is unchanging, the numbers of the pistons of the hydraulic oil cylinder are increased in order to increase the working area of the hydraulic oil cylinder, and thereby, the working pressure of the hydraulic oil cylinder is enhanced for many times. The multi-cavity oil cylinder has convenient manufacture, easy assemblage, and low cost.
Description
The utility model belongs to the improvement to hydraulic jack.
Have only an oil pocket in the common hydraulic jack, under the hydraulic pressure of certain pressure intensity, because piston area is certain, the working pressure of generation is certain.The purpose of this utility model is to improve hydraulic jack, under the constant operating conditions of pressure, does not increase the physical dimension of oil cylinder circumferencial direction, and the number of pistons by increasing oil cylinder so that increase the work area of oil cylinder, thereby significantly improve the working pressure of oil cylinder.
The utility model mainly is in cylinder block inside cylinder sleeve to be housed, and several reinforcement pistons are housed in the cylinder sleeve from bottom to up, by several dividing plates space in the oil cylinder is divided into several cavitys between each reinforcement piston.Each reinforcement piston can move up and down in the dividing plate pilot hole, and a working piston is equipped with in the oil cylinder the top.Also be provided with seal ring and sealing cover on the oil cylinder.
Accompanying drawing is a Multiple cavity oil cylinder structure cross-sectional schematic.
Cylinder sleeve (2) is equipped with in cylinder block (1) inside, and several reinforcement pistons (3) are housed in the cylinder sleeve from bottom to up, by several dividing plates (4) space in the oil cylinder is divided into several little spaces between each reinforcement piston.Each reinforcement piston can move up and down in dividing plate pilot hole (5).A working piston (6) is equipped with in the oil cylinder top.Seal ring (7) and sealing cover (8) also are equipped with in oil cylinder top.
The utility model is easily manufactured, is easy to assembling, and is with low cost, is widely used.
Claims (3)
