Abstract
The utility model relates to a hydraulic cylinder with a guide sleeve arranged outside. The hydraulic cylinder comprises a hydraulic cylinder body (1) with a rightward opening, a piston rod (2) is arranged in the hydraulic cylinder body (1), the left end of the piston rod (2) is connected with a piston (3), the right end of the piston rod (2) extends out of the hydraulic cylinder body (1), and a flange (4) is arranged at the right end of the hydraulic cylinder body (1). The hydraulic cylinder is characterized in that the right side of the flange (4) is connected with the guide sleeve (5). The hydraulic cylinder with the guide sleeve arranged outside has the advantages that maintenance can be performed without dismounting the hydraulic cylinder, and the operation is convenient.
Description
Technical field
The utility model relates to a kind of external guide sleeve oil cylinder, belongs to the oil cylinder technical field.
Background technique
Oil cylinder is oil hydraulic cylinder, and oil hydraulic cylinder is the straight line moving type executive component that the pressure reduction on ouput force and piston effective area and both sides thereof is directly proportional.The guide sleeve of tradition oil cylinder is integrated with flange plate, or in the inboard cylinder body of flange plate, when guide sleeve breaks down, the guide sleeve integral replacing that will be integrated with flange plate, be exactly to remove flange plate the guide sleeve in cylinder body is taken out and changes, these two kinds of structures all need to pull down oil cylinder when Maintenance and Repair to be processed, comparatively loaded down with trivial details.Therefore seeking does not a kind ofly need to pull down oil cylinder and gets final product Maintenance and Repair, and easy to operate oil cylinder is particularly important.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned deficiency, and providing a kind of does not need to pull down oil cylinder and get final product Maintenance and Repair, easy to operate external guide sleeve oil cylinder.
The purpose of this utility model is achieved in that
A kind of external guide sleeve oil cylinder, it comprises opening cylinder block to the right, be provided with piston rod in described cylinder block, the left end of described piston rod is connected with piston, the right-hand member of described piston rod stretches out the cylinder block outside, the right-hand member of described cylinder block is provided with flange plate, and the right side of described flange plate is connected with guide sleeve.
As a kind of preferred, the center, right side of described flange plate is provided with the groove of hoop, and the center, left side of described guide sleeve is provided with bulge loop, and described bulge loop is embedded in groove.
As a kind of preferred, be provided with two seals circle and one dust ring on the inwall of described guide sleeve.
Compared with prior art, the beneficial effects of the utility model are:
The utility model is because guide sleeve is positioned at the outside of flange plate, and removably connects with guide sleeve and flange plate, when guide sleeve breaks down, only need directly change and get final product from the outside guide sleeve of removing of oil cylinder.Therefore this external guide sleeve oil cylinder has does not need to pull down oil cylinder and gets final product Maintenance and Repair, easy to operate advantage.
The accompanying drawing explanation
The structural representation that Fig. 1 is the external guide sleeve oil cylinder of the utility model.
