Description

Oil hydraulic cylinder

Technical field

The utility model relates to a kind of oil hydraulic cylinder.

Background technique

The stroke of common oil hydraulic cylinder and mounting point (the cylinder bottom earrings is to the centre distance of rod end earrings) are all fixed.The supporting that needs in the using process to be hinged with earrings must be a locality specific, for bearing position accurately occasion be difficult to satisfy the needs of mounting distance and stroke.

Summary of the invention

It is adjustable and be convenient to the oil hydraulic cylinder installing and use that the purpose of this utility model just provides a kind of outer stroke.

The technical solution of the utility model is achieved in that a kind of oil hydraulic cylinder, it mainly is made up of cylinder bottom piston, cylinder barrel, piston rod, cylinder head, earrings, wherein: the bar tail of piston rod links to each other with piston, the bar head is connected with earrings, cylinder barrel and cylinder bottom are weldingly connected, cylinder barrel end in addition is threaded with cylinder head, and piston rod assembly is contained in the cylinder assembly, is provided with to adjust cover between cylinder head and earrings.

The utility model has the advantages that: simple in structure, compact, make the stroke of oil hydraulic cylinder adjustable, be convenient to the I﹠M of oil hydraulic cylinder, operate steadily.

Description of drawings

Fig. 1 is a structural representation of the present utility model.

Embodiment

As shown in Figure 1, a kind of oil hydraulic cylinder, it mainly is made up of cylinder bottom 1, piston 2, cylinder barrel 3, piston rod 4, cylinder head 5, earrings 7, wherein: the bar tail of piston rod 4 links to each other with piston 2, the bar head is connected with earrings 7, and cylinder barrel 3 is weldingly connected with cylinder bottom 1, and cylinder barrel 3 end in addition is threaded with cylinder head 5, piston rod assembly is contained in the cylinder assembly, is provided with to adjust cover 6 between cylinder head 5 and earrings 7.Between piston 4 and cylinder bottom 1, be reserved with a segment distance as blank stroke, thus can be by changing the stroke that the axial length of adjusting cover 6 changes oil hydraulic cylinder, and the mounting point that the oil hydraulic cylinder release is returned is adjustable, is convenient to the I﹠M of oil hydraulic cylinder.
