Abstract
The utility model relates to a horizon hydraulic cylinder sealing element which is applicant for avoiding hydraulic-oil leakage along the cylinder rod surface, which comprises a ring (1) with an H-type cross section, an inner O-type ring and an outer O-type ring, a plurality of oil leakage holes (5) are penned on the middle portion of the lateral side of the ring (1) with an H-type cross section, an inner O-type ring block (7) is provided in the inner side of the external end thereof, and an outer O-type ring block (9) is provide on the outer side of the external end thereof. The inner O-type ring is equipped in the inner O-type ring block (7) and the outer O-type ring is equipped in the outer O-type ring block (9). The utility model has the advantages of simple structure, and only changing of the inner and outer O- type rings is needed.
Description
Affiliated technical field
The utility model relates to a kind of Sealing of horizontal hydraulic cylinder, is applied to prevent that hydraulic oil from leaking along piston rod surface.
Background technique
For the oil hydraulic cylinder of the horizontal positioned work of, reciprocating in the horizontal direction with the piston rod that piston connects together.In order to prevent the leakage of hydraulic oil, need be at guide sleeve with piston rod bonding crack arranged outside packing, stop hydraulic oil along piston face to external leakage.Mostly packing is to adopt polytetrafluoroethylmaterial material to make, and becomes circular, tightly is enclosed within the piston rod outside, snaps in the cylinder body annular groove fixing.Because leakage phenomenon often appears in wearing and tearing very soon.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned the deficiencies in the prior art part, and a kind of Sealing of postponing the horizontal hydraulic cylinder of leakage phenomenon time of occurrence is provided, and it is placed in the packing middle part and uses, and that is to say that its inside and outside both sides all are packings.
The purpose of this utility model can reach like this, and a kind of Sealing of horizontal hydraulic cylinder is characterized in that by the transverse section being that the annulus of I-shaped, interior O shape are enclosed, outer O shape circle is formed; The middle part, side of I-shaped annulus has some oil leaking holes, and O shape circle draw-in groove, the outside, outer end had outer O shape circle draw-in groove in the inboard, outer end had; Among the O shape circle draw-in groove, outer O shape circle placed among the outer O shape circle draw-in groove in interior O shape circle placed.
The utility model has following advantage compared to existing technology:
1, simple in structure;
2, only need to change inside and outside O shape circle.
Description of drawings
Fig. 1 is the utility model I-shaped annulus embodiment's a plan view
1 is the I-shaped annulus among the figure, the 3rd, fixedly use screw.
Fig. 2 is that the A-A of Fig. 1 is to sectional view
5 is oil leaking holes among the figure, the 3rd, and fix and use screw, the 7th, interior O shape circle draw-in groove, the 9th, outer O shape circle draw-in groove
Fig. 3 is that the B-B of Fig. 2 is to sectional view
5 is oil leaking holes among the figure
Embodiment
The utility model is further described below in conjunction with accompanying drawing.A kind of Sealing of horizontal hydraulic cylinder, it has the annulus that the transverse section is an I-shaped (1), and the middle part, side of I-shaped annulus (1) has some oil leaking holes (5), and O shape circle draw-in groove (7), the outside, outer end had outer O shape circle draw-in groove (9) in the inboard, outer end had; Among the O shape circle draw-in groove (7), an outer O shape circle placed among the outer O shape circle draw-in groove (9) in O shape circle placed in one.
During use, I-shaped annulus (1) is enclosed within the piston rod outside, makes the piston rod transverse horizontal pass annulus (1) inside, and the piston rod outer surface contacts with the interior O shape circle in the O shape circle draw-in groove (7) in placing.Outer O shape circle in the outer O shape circle draw-in groove (9) then closely contacts with cylinder body.I-shaped annulus (1) can be fixed on the packing of interior edge face one side by the screw on the interior edge face (3).The exterior edge face of I-shaped annulus (1) then closely contacts with the packing of exterior edge face side.So I-shaped annulus (1) is clipped in wherein by the packing of inside and outside both sides, the three is being pressed with cylinder body by the gland of cylinder body and is keeping one.Open an oil duct on the cylinder body, lead to the minimum oil leaking hole (5) at middle part, I-shaped annulus (1) side from low to high, the oil duct the other end then leads to the leakage of oil trap.When piston rod moved reciprocatingly, because inside and outside O shape circle is stuck by inside and outside O shape circle draw-in groove (7,9) respectively, two O shapes circle can not be damaged because of following piston rod movement.Simultaneously, inner side panel root have a little leakage of oil the time, also can flow out and be collected from the oil leaking hole (5) of lowest part, outwards do not flow out directly along piston rod surface thereby do not have leakage of oil.Have only when the leakage of oil flow greatly to can not just having leakage of oil and flow to the external world when oil duct in time flow away along piston rod surface.So just avoided in the prior art one to have a little leakage of oil to flow to extraneous shortcoming, postponed the time that leakage phenomenon occurs from piston rod surface.
