Background technology
Traditional piston and guide sleeve, mainly using metal material, when running into sealing and going wrong with other fortuitous events,
Piston is easy to directly produce CONTACT WITH FRICTION with cylinder barrel, so as to pull cylinder barrel；Guide sleeve contacts with piston rod direct friction, damage
Piston rod.Very big difficulty is brought to later period maintenance, also maintenance cost is greatly increased.
Utility model content
The utility model overcomes the shortcomings of the prior art, there is provided a kind of novel piston and guide sleeve structure, solution
Determine in colliery class jack and oil cylinder class product, because cylinder barrel directly contacts with piston, piston rod directly contacts with guide sleeve,
Produce cylinder barrel and pull the problem of being pulled with piston rod.
In order to solve the above-mentioned technical problem, the technical solution adopted in the utility model is：A kind of novel piston and guide sleeve
Structure, including cylinder barrel, piston, guide sleeve, cylinder cap and piston rod, the cylinder barrel are closed for one end, the structure of another end opening, institute
State cylinder barrel openend inner chamber and be fixedly installed guide sleeve, the openend end set of the cylinder barrel has cylinder cap, the piston activity
Be arranged on the inner chamber of cylinder barrel, the piston rod connects one end and is connected on piston, the other end of the piston rod through guide sleeve and
Cylinder cap is reached outside cylinder barrel, and the material of the piston and guide sleeve is PA6, or is PA66, or is PAll, or is PAl2, or
For PA46, or it is PA610, or is PA612, or is PAl010.
The first sealing ring is provided between piston and the inner cavity of cylinder wall, the section of first sealing ring is in convex,
It is corresponding to be inlaid in the Baltimore groove of piston face.
It is provided with the second sealing ring between the guide sleeve and piston rod, second sealing ring is flower bud shape sealing ring, institute
The matching of the second sealing ring is stated to be fixedly installed on guide sleeve.
It is respectively arranged with inlet and liquid outlet on the lateral wall of the cylinder barrel, the inlet and liquid outlet are and cylinder barrel
Inner chamber connects, and is located at the both sides of piston respectively.
The utility model has an advantageous effect in that compared with prior art：The utility model piston and guide sleeve are using new
Section bar material wear resistant nylon replaces traditional metal material, avoids cylinder barrel and pulls and is pulled with piston rod, reduce later period maintenance into
This, shortens maintenance cycle.
Brief description of the drawings
The utility model is described further below in conjunction with the accompanying drawings.
Fig. 1 is structural representation of the present utility model.
In figure：1 it is cylinder barrel, 2 be piston, 3 be guide sleeve, 4 be cylinder cap, 5 be piston rod, 6 be the first sealing ring, 7 is
