Description
Technical field
It the utility model is related to vehicle technical field of hydraulic oil cylinder, and in particular to a kind of hydraulic oil with springlock
Cylinder.
Background technology
Hydraulic jack is a kind of using quite varied industrial automation arrangement, and its structure is usually to load to lead in cylinder barrel
To set, then the component such as piston and piston rod is installed in guide sleeve, however, guide sleeve is conducted oneself with dignity in transverse load and piston rod
Uneven wear is easily caused under effect, the sealing property in turn resulting in the hydraulic jack substantially reduces, or even causes hydraulic oil
Leakage, it is therefore desirable to provide a kind of hydraulic jack to overcome defect described in prior art.
Utility model content
Technical problem to be solved in the utility model is to be directed to above-mentioned the deficiencies in the prior art,
A kind of hydraulic jack with buffer-oriented set is provided.
To achieve the above object, the utility model provides following technical scheme：A kind of hydraulic pressure with buffer-oriented set
Oil cylinder, include the cylinder barrel and guide sleeve being contained in cylinder barrel, piston and piston rod, it is characterised in that：The guide sleeve
One end of cylinder barrel is anchored on, the piston moves along cylinder barrel bearing of trend, and described piston rod one end is connected to piston and promotes work
Plug motion, the piston rod pass through guide sleeve, and the guide sleeve is buffering end relative to the other end of connection cylinder barrel one end, described
Buffer unit is provided between buffering end and piston.
Using above-mentioned technical proposal, buffering end, Ran Hou are set relative to the other end of connection cylinder barrel one end in guide sleeve
Buffer unit is set between buffering end and piston, can play a part of increasing guide sleeve service life, in piston rod to guiding
When set is close, the buffer unit of setting can also play a part of buffering.
A kind of above-mentioned hydraulic jack with buffer-oriented set can be further arranged to：The buffer unit includes buffering
The cushion pad set is held, the piston rod is arranged with buffer spring close to one end of piston, and described buffer spring one end is welded in
Piston.
Using above-mentioned technical proposal, cushion pad is set at buffering end, then delayed in piston rod close to one end winding of piston
Rush spring, material is thus formed a buffer unit, can play when piston rod to reduced during one end motion of guide sleeve piston with
Mechanical friction between guide sleeve, and the buffer spring set can play a part of protecting piston.
A kind of above-mentioned hydraulic jack with buffer-oriented set can be further arranged to：The buffer spring external diameter is smaller
In internal diameter of cylinder.
Using above-mentioned technical proposal, buffer spring external diameter is less than internal diameter of cylinder, because when piston rod movement, if buffering
The external diameter of spring is big as internal diameter of cylinder, then is rubbed between buffer spring meeting and cylinder barrel, can damage inner wall of cylinder on the contrary.
A kind of above-mentioned hydraulic jack with buffer-oriented set can be further arranged to：Between the buffering end and cylinder barrel
Provided with gap, sealing ring is provided with the gap.
Using above-mentioned technical proposal, sealing ring is set in the gap between buffering end and cylinder barrel, buffering end can be improved
Sealing between cylinder barrel, and can prevent from buffering between end and cylinder barrel and mechanical friction occurs.
A kind of above-mentioned hydraulic jack with buffer-oriented set can be further arranged to：The cushion pad front end is provided with rubber
Rubber gasket, the rubber washer are made up of hydrogenation nitrile rubber.
Using above-mentioned technical proposal, hydrogenated nitrile-butadiene rubber has good oil resistance（To fuel oil, lubricating oil, aromatic series
Solvent resistance is good）；And due to its HI SA highly saturated structure, it is set to have good heat resistance, excellent chemically-resistant is rotten
Corrosion energy（There is good resistance to freon, acid, alkali）, excellent ozone resistance, higher incompressible permanent change
Shape performance；Hydrogenated nitrile-butadiene rubber also has high intensity simultaneously, high tear energy, the features such as anti-wear performance is excellent, is especially suitable for making
In the working environment of hydraulic jack.
A kind of above-mentioned hydraulic jack with buffer-oriented set can be further arranged to：The guide sleeve passes through some tight
Gu screw is anchored on cylinder barrel.
Using above-mentioned technical proposal, be directed to set by several trip bolts and be fixed on cylinder barrel one end, be connected firmly and
It is convenient to set.
The beneficial effects of the utility model are：By setting the buffer unit guiding between guide sleeve and piston rod
Will not be worn between set and piston rod long-term motion so that the sealing property of whole hydraulic jack is preferable, service life compared with
It is long.
The utility model is described in further detail with reference to the accompanying drawings and examples.
