The normal use of telescopic arm is rung, and repairs complexity, it is extremely inconvenient.
Utility model content
The purpose of this utility model is to propose a kind of telescopic steel pipe, and the telescopic steel pipe is stretched with the flexible of telescopic arm
Contracting, ensure that oil pipe both ends connect all the time, reduce pipeline arrangement, be easily installed maintenance, service life length.
Telescopic steel pipe described in the utility model, including telescoping tube and adjustment oil cylinder, telescoping tube include socket and hollow oil
Pipe, the inside of hollow oil pipe are provided with middle vestibule, and hollow oil pipe is stretched in socket, and hollow oil pipe external part is provided with close on socket
Seal guider；Adjustment oil cylinder includes cylinder barrel and piston rod, and piston rod stretches in cylinder barrel；The outside dimension of hollow oil pipe is equal to
The internal diameter size of oil cylinder is adjusted, the middle vestibule diameter dimension of hollow oil pipe is equal to the diameter of piston rod size of adjustment oil cylinder, socket
The internal rod chamber with adjusting oil cylinder is connected by connected pipes, is filled with the rod chamber of connected pipes, socket and adjustment oil cylinder
Fluid, the rodless cavity for adjusting oil cylinder lead to air；The socket of telescoping tube and the cylinder barrel of adjustment oil cylinder are fixed together, hollow oil pipe
Telescopic end is fixedly connected with piston rod head.
The fixing end of hollow oil pipe and piston rod is fixedly connected on the joint arm front end of telescopic arm one, the socket of telescoping tube and adjustment
The cylinder barrel of oil cylinder is fixedly connected on another joint arm rear end of telescopic arm.When telescopic arm is overhanging, drive telescoping tube hollow oil pipe and
It is synchronously protruding to adjust the piston rod of oil cylinder, the increase of telescoping tube internal volume, adjusts cylinder rod chamber volume reducing, both number
Be worth it is equal, adjustment cylinder rod chamber discharge fluid flowed to by connected pipes in telescoping tube, make the fluid in telescoping tube timely
Obtain supplement adjustment.
When telescopic arm is retracted, the hollow oil pipe and adjustment cylinder piston rod that drive telescoping tube are synchronously retracted inwards, are stretched
Pipe internal volume is reduced, and the volume increase of adjustment cylinder rod chamber, both numerical value is equal, and the fluid of discharge passes through connection in telescoping tube
Oil pipe is flowed in adjustment cylinder rod chamber, the fluid in telescoping tube is adjusted in time.Sealing guider can ensure to manage
Cylinder is oil-proof, and hollow oil pipe is not produced and rocked.
Preferably, described connected pipes one end connection socket, the end of other end connection adjustment cylinder rod chamber.
Possessed beneficial effect is the utility model compared with prior art：
The utility model is reasonable in design, and the telescopic steel pipe stretches with the flexible of telescopic arm, ensures oil pipe both ends
All the time connect, reduce pipeline arrangement, be easily installed maintenance, service life length.
