Abstract

The utility model discloses a grass gripping oil cylinder for a loading machine. The grass gripping oil cylinder for the loading machine is characterized in that one end of a cylinder barrel and a cylinder bottom are welded, the other end of the cylinder barrel and a guide sleeve are screwed by threads, a piston rod is sheathed in the cylinder barrel by the guide sleeve, a locking nut for fastening is arranged behind the piston, a sliding seal and a support ring are arranged at a piston outer groove, a first O-shaped ring is arranged in an inner groove, a dustproof ring, a piston rod seal ring, a support ring and axial stepped seal are arranged in a guide sleeve inner groove, and a second O-shaped ring is arranged in a guide sleeve outer groove. Through the arrangement, the grass gripping oil cylinder for the loading machine is compact in structure, good in sealing effect and reliable in working performance.

Description

A kind of loader is with grabbing careless oil cylinder

Technical field

The utility model relates to a kind of oil cylinder, is that a kind of loader is with grabbing careless oil cylinder specifically.

Background technique

Loader is with grabbing careless oil cylinder, and its volume is little, operating time work is long, and poor working environment requires it must possess good sealing and property durable in use.

Summary of the invention

The utility model has been designed and developed out compact structure for the specific (special) requirements of present loader, and the good loader of functional reliability is with grabbing careless oil cylinder.

The utility model is achieved through the following technical solutions:

Cylinder barrel one end and cylinder bottom welding, the other end and guide sleeve screw by screw thread, piston rod is linked in the cylinder barrel by guide sleeve, the end that piston rod inserts in the cylinder barrel is provided with piston, it is fastening to be provided with locking nut behind piston, in the piston outer channel slipper seal and support ring is installed, and internal channel is installed an O type circle, seal with ladder at guide sleeve internal channel installation dust ring, rod seal circle, support ring, axle, outer channel is installed the 2nd O type circle.

By above setting, the utility model compact structure, sealing effect is good, reliable working performance.

Description of drawings

Now the utility model is described in further detail by reference to the accompanying drawings.

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

Among the figure: 1, piston rod, 2, guide sleeve, 3 cylinder barrels, 4, piston, 5, locking nut, 6, cylinder bottom, the 7, first support ring, 8, slipper seal, the 9, the one O type circle, the 10, second support ring, 11, axle seals with ladder, and 12, the rod seal circle, the 13, the 2nd O type circle, 14, dust ring.

Embodiment

Cylinder barrel 3 one ends and cylinder bottom 6 welding, the other end and guide sleeve 2 screw by screw thread, piston rod 1 is linked in the cylinder barrel 3 by guide sleeve 2, the end that piston rod 1 inserts in the cylinder barrel 3 is provided with piston 4, it is fastening to be provided with locking nut 5 behind piston 4, in piston 4 outer channel slipper seal 8 and the first support ring 7 is installed, and internal channel is installed an O type circle 9, seal 11 at guide sleeve 2 internal channel installation dust ring 14, rod seal circle 12, the second support ring 10, axle with ladder, outer channel is installed the 2nd O type circle 13.By above setting, during overhanging and retraction, the first support ring 7 provides side direction bearing capacity, impact-absorbing to the utility model when piston rod 1; Slipper seal 8 anti impulsion loads have the high resistance extrusion capability, play the two way sealed effect; The impurity such as dust of dust ring 14 outside the lip scraping piston rod 1 in the external world is wiped oil-film removing towards the lip of oil cylinder medium; 12 liang of lips of rod seal circle are tight clamping piston bar under the pressure of high-pressure medium, plays main seal action; Axle plays the one-way sealing effect with ladder envelope 11, stops medium leakage in the oil cylinder; The 2nd O type circle 13 is the compressional deformation sealing under the fluid pressure effect, stops the interior medium of oil cylinder to be revealed by guide sleeve and cylinder barrel surface of contact.

Claims

1. a loader is with grabbing careless oil cylinder, it is characterized in that: cylinder barrel one end and cylinder bottom welding, the other end and guide sleeve screw by screw thread, piston rod is linked in the cylinder barrel by guide sleeve, and the end that piston rod inserts in the cylinder barrel is provided with piston, and it is fastening to be provided with locking nut behind piston, in the piston outer channel slipper seal and support ring are installed, internal channel is installed an O type circle, seals with ladder at guide sleeve internal channel installation dust ring, rod seal circle, support ring, axle, and outer channel is installed the 2nd O type circle.
