Abstract
The utility model relates to a broadband sealing ring with monosomic hydraulic pressure column, which is characterized in that: a sealing cavity which can effectively block emulsion liquid is formed through the broadband sealing ring for the piston head for the cylinder barrel and the movable column; outer seal band is broadened at the inner diameter of the cylinder barrel and the seal part of the sealing ring; a sealable broadened concave part is arranged at the sealing ring at the joint part of the piston head and the sealing ring and can be integrated with the piston head into an inner sealing band surface. The utility model has the advantages of forming broadband sealing toward the cylinder wall and the sealing surface for the piston head after pressured, not affecting the column speed if unloaded, having obvious sealing result, prolonging using cycle, having simple structure, economy and practical using and being an ideal sealing ring with monosomic hydraulic column.
Description
Affiliated technical field
The utility model relates to a kind of hydraulic prop O-ring seal device.
Background technique
At present, known hydraulic prop structure is made up of Y shape O-ring seal, piston head, oil cylinder, but Y shape cushion rubber external sealed band is narrow, and life cycle is short, and the maintenance expenses height easily leaks and produces, and causes uneasy golden hidden danger easily.
Summary of the invention
Narrow for existing Y shape O-ring seal external sealed band for oral administration, life cycle is short, easy deficiency of leaking, and the utility model provides a kind of broadband O-ring seal, and this broadband O-ring seal can not only solve the problem of leakage, and simple in structure, and is economical and practical.
The technological scheme that its technical problem that solves the utility model adopts is: the piston head on the cylinder barrel and the post of living is the airtight chamber that forms effective shutoff emulsified liquid by the broadband O-ring seal, internal diameter and O-ring seal sealing part at cylinder barrel have been widened the external sealed band, be provided with sealable again with protrusion piston head place and O-ring seal joint, widen, recess can block with piston head all-in-one-piece inner seal band, the pressurization back is to cylinder wall, the sealing surface of piston head forms the broadband sealing, unloading does not influence prop drawing speed, and the prolongation life cycle, make sealing effect reach more reliable purpose.
The beneficial effects of the utility model are: just tumble in the broadband O-ring seal on piston head, it is simple in structure, and is economical and practical.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is the schematic representation of hydraulic prop of the present utility model broadband O-ring seal.
Embodiment
The O-ring seal of widening external sealed band (1) (4) of a vulcanization forming fuses with the piston head of hydraulic prop styletable head alive in Fig. 1, make the recess (2) that can match with the piston head projection at the internal diameter of broadband O-ring seal (4), be provided with again with O-ring seal (4) at the internal diameter of sealing circle (4) and imitate sealing all-in-one-piece inner seal band (3) in the recess (2) of vulcanization forming and with piston head simultaneously, during use, after the pressurization of hydraulic prop cylinder internal emulsification liquid, the external sealed band (1) of broadband O-ring seal (4) reliably is affixed to the purpose that oil cylinder inner wall reaches strong sealing.
Claims (1)
1, a kind of hydraulic prop broadband O-ring seal, piston head on the cylinder barrel and the post of living is the airtight chamber that forms effective shutoff emulsified liquid by broadband O-ring seal (4), it is characterized in that having widened external sealed band (1) at the internal diameter of cylinder barrel and the sealing part of O-ring seal (4), with piston head place and O-ring seal (4) joint also be provided with sealable, the recess of widening (2) can block with piston head all-in-one-piece inner seal band (3).
