Description
Technical Field
The utility model belongs to the technical field of the rubber seal technique and specifically relates to indicate an oil-resistant type sealing rubber circle is used to machinery.
Background
The rubber sealing ring is an elastic sealing structure which takes natural rubber as raw material. The natural rubber becomes soft when heated, becomes hard when cooled, becomes brittle, is difficult to form and easy to wear, is easy to dissolve in organic solvents such as gasoline and the like, has double bonds in molecules, is easy to perform addition reaction and is easy to age. Therefore, in the prior art, various synthetic rubbers have been developed to solve these problems by studying the properties of the rubber, but since the main component is still rubber, how to achieve better oil resistance is to be solved from the viewpoint of the structure thereof, and it is necessary to provide an oil-resistant sealing rubber ring to solve the above problems.
SUMMERY OF THE UTILITY MODEL
The to-be-solved technical problem of the utility model is to provide a machinery is with resistant oil type sealing rubber circle, grease proofing effectual, simple structure, it is sealed effectual.
In order to solve the technical problem, the utility model discloses a following technical scheme:
the utility model provides an oil-resistant type sealing rubber circle is used to machinery, includes the rubber circle body, the oil storage tank has been seted up respectively at the both ends of rubber circle body, the inside of rubber circle body is equipped with expansion block, the coating of oil storage tank inner wall has grease proofing coating.
Furthermore, a plurality of reinforcing columns are uniformly arranged in the oil storage tank at intervals.
Furthermore, one end of the reinforcing column is integrally connected with the bottom of the oil storage tank, and the other end face of the reinforcing column is as high as the tank wall of the oil storage tank.
Furthermore, the wall of the oil storage tank is subjected to rounding treatment, and an oil absorption gasket is attached to the chamfer.
Further, the expansion assembly comprises an annular cavity which is formed in the rubber ring body, and a plurality of metal spring wires are arranged in the annular cavity at intervals.
The utility model has the advantages that:
in an actual use situation, oil storage grooves are formed in two ends of the rubber ring body, an oil-proof coating is coated on the inner wall of each oil storage groove, the oil-proof coating takes butyl rubber as a film forming agent, and a vinyl resin mixed with a hydrophilic high polymer can form an oil-resistant film which is attached to the surface of rubber so that oil can be stored in the oil storage grooves; expansion assembly can make the rubber circle body have certain compressibility, and when the installation, extrusion rubber circle body makes its card go into the seal groove, then utilizes expansion assembly's resilience force to support the tight card at the seal groove with the rubber circle body, strengthens sealed effect. The utility model discloses grease proofing effectual, simple structure, it is sealed effectual.

Detailed Description
In order to facilitate understanding of those skilled in the art, the present invention will be further described with reference to the following examples and drawings, which are not intended to limit the present invention.
As shown in fig. 1-3, the utility model provides an oil-resistant type sealing rubber circle is used to machinery, including rubber circle body 1, oil storage tank 2 has been seted up respectively at the both ends of rubber circle body 1, the inside of rubber circle body 1 is equipped with expansion block 3, the coating of 2 inner walls of oil storage tank has grease proofing coating.
In the embodiment, the oil storage grooves 2 are formed in the two ends of the rubber ring body 1, the inner wall of each oil storage groove 2 is coated with the oil-proof coating, the oil-proof coating takes butyl rubber as a film forming agent, and the vinyl resin mixed with the hydrophilic high polymer can form an oil-resistant film with excellent performance and be attached to the surface of rubber, so that the oil in the oil storage grooves 2 can be resisted; expansion assembly 3 can make rubber circle body 1 have certain compressibility, and when the installation, extrusion rubber circle body 1 makes its card go into the seal groove, then utilizes expansion assembly 3's resilience force to support tight card at the seal groove with rubber circle body 1, strengthens sealed effect. This rubber circle is grease-proof effectual, simple structure, and is sealed effectual.
As shown in fig. 1, a plurality of reinforcing columns 21 are uniformly arranged in the oil storage tank 2 at intervals; in this embodiment, the reinforcing column 21 plays the effect of auxiliary stay mechanical seal groove, prevents that the cell wall of oil storage tank 2 from supporting the power and causing the serious condition of deformation of installation to take place inadequately, utilizes support column 21 interval support, does not influence the intensity of rubber circle when guaranteeing the normal oil storage of oil storage tank 2.
As shown in fig. 2, one end of the reinforcing column 21 is integrally connected with the bottom of the oil reservoir 2, and the other end surface of the reinforcing column 21 has the same height as the wall of the oil reservoir 2; in this embodiment, when production and processing, the reinforcing column 21 and the oil storage tank 2 adopt the integrative injection molding of unified mould with the rubber circle body 1, and the material is the same, and is not fragile.
As shown in fig. 1, the wall of the oil storage tank 2 is chamfered, and an oil absorption gasket 22 is attached to the chamfer; in this embodiment, in the cell wall of oil storage tank 2 was done the radius angle and is handled and more make things convenient for the greasy dirt to flow into oil storage tank 2 along the chamfer direction, chamfer department has attached oil absorption gasket 22, and oil absorption gasket 22 can adopt the oil absorption cotton to make, can just adsorb the collection with the greasy dirt when initial contact greasy dirt, in the oil storage tank 2 is flowed down to the chamfer in following the saturation back, and grease proofing effect is better.
As shown in fig. 3, the expansion assembly 3 includes an annular cavity 31 formed inside the rubber ring body 1, and a plurality of metal spring wires 32 are arranged at intervals in the annular cavity 31; in this embodiment, adopt thinner metal spring wire 32 integrative the pouring processing when processing rubber circle body 1, when using rubber circle body 1, apply certain effort to the both ends of rubber circle body 1, can compress rubber circle body 1 and inside metal spring wire 32, conveniently install it in the seal groove this moment, then utilize metal spring wire 32's resilience to enclose body 1 inflation chucking with whole rubber in the seal groove, the effectual dropping that prevents to strengthen the leakproofness.
All technical features in the embodiment can be subjected to appearance modification according to actual needs.
The above-mentioned embodiment is the utility model discloses the implementation scheme of preferred, in addition, the utility model discloses can also realize by other modes, any obvious replacement is all within the protection scope of the utility model under the prerequisite that does not deviate from this technical scheme design.
