Description
Technical field
The utility model belongs to technical field of fluid delivery, is specifically related to a kind of improvement of hydraulic oil supply system structure.
Background technique
Traditional hydraulic pressure oil feed line mainly contains hard metal pipe or flexible hose.
Hard metal pipe is fixed installation, its length of pipe is immutable, and flexible high pressure hose bends the length changing pipeline by pipeline, the change of size on pipeline radial cross section can be caused when flexible hose bends, need the reserved larger flexible hose curved space.
Therefore, hard metal pipe and flexible hose need to change length of pipe and on pipeline radial cross section the occasion of size-constrained system all inapplicable.
Summary of the invention
The utility model provides a kind of passive telescopic hydraulic oil feed line to overcome the deficiency of hard metal hydraulic pipe line and flexible hydraulic pipe line.
The utility model solves the technological scheme that its technical problem adopts: a kind of passive telescopic hydraulic oil feed line, be made up of fixed cylinder body and telescopic interior pipe, between cylinder body and interior pipe, guide ring is housed, interior pipe upper end is connected with transition head, cylinder head is equipped with in cylinder body upper end, O-ring seals is equipped with between interior pipe and transition head and between cylinder body and cylinder head, decontamination ring is equipped with on cylinder head top, the cushion pad be connected with cylinder head is provided with above decontamination ring, cylinder head is built with the support ring for supporting interior pipe, one-way sealing seal for sealed inner tube and two-way sealing ring are also housed in cylinder head, cylinder body lower end is connected with base by screw and snap ring, base bottom and sidepiece are respectively equipped with lower contact and plug.
The passive telescopic hydraulic oil feed line of described one, is provided with one or more transition spool piece between pipe and cylinder body in it.
The passive telescopic hydraulic oil feed line of described one, its multiple transition spool piece is coaxial nested encryptions structure.
The beneficial effects of the utility model are: the length of pipeline can change along pipeline axis, and on pipeline radial cross section size and conduit positions constant, need when being applicable to work to change length of pipe but the hydraulic equipment of size-constrained system on pipeline radial cross section, it is passive telescopic that length of pipe changes employing, without the need to active power source, length of pipe changes along pipeline axis, on pipeline radial cross section size and conduit positions constant, save installing space, configurable multiple standards pipe interface, compact structure, the characteristic such as easy for installation.
