Abstract
The utility model provides an oil filtering device. An oil pipe connecting part is arranged at one end of an oil filter joint, a filter element constituted by a framework and a filter screen is arranged at the other end of the oil filter joint, an annular boss is arranged at the middle part of the oil filter joint, an annular groove is arranged on the side surface facing towards the filter screen of the annular box on the oil filter joint and a seal ring is fixed in the annular groove, so that the seal ring can not deform or move due to various external factors during long-term working and the oil filtering device disclosed by the utility model has the advantages of stable sealing property and the like.
Description
Technical field
The utility model belongs to technical field of engines, refers in particular to a kind of oil-filtering apparatus.
Background technology
At present; Various servicing units are arranged in the fuel system, and like oil pipe, carburetor etc., wherein the effect of oil-filtering apparatus is to filter to be mixed in the impurity in the fuel oil; The particulate contamination that contains in the hydraulic oil; Can cause the obstruction of engine fuel system, the system works reliability is greatly reduced, therefore the operate as normal that oil-filtering apparatus can guarantee system is installed; Sealing when other device is connected in oil-filtering apparatus and the fuel system is very important; The sealing ring of existing oil-filtering apparatus is to be set directly between oil-filtering apparatus and other device, oil-filtering apparatus is connected the back with other device since work for a long time or the dynamics that compresses during connection can cause sealing ring mobile, be out of shape, cause the instability of sealing.
Summary of the invention
The purpose of the utility model provides the stable oil-filtering apparatus of a kind of sealing.
The purpose of the utility model is achieved in that
A kind of oil-filtering apparatus; One end of oil filter joint is provided with oil pipe connecting portion, the other end and is provided with filter core, the middle part that band is made up of skeleton and filter screen and is provided with annular boss, it is characterized in that the annular boss that said oil is filtered on the joint is provided with annular groove towards the side of filter screen.
The cross section of above-mentioned annular groove is rectangular configuration or semicircular structure or half elliptic structure.
Be provided with O-ring seal in the above-mentioned annular groove.
The utility model compared with prior art has following beneficial effect:
The boss of the utility model is provided with annular groove, and sealing ring is fixed in the annular groove, makes sealing ring not producing distortion or mobile because of the various factors in the external world in the work for a long time, has stable sealing.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Among the figure: 1, oil filter joint; 11, connecting portion; 12, annular boss; 121, annular groove; 2 filter cores; 21, skeleton; 22, filter screen.
The specific embodiment
The utility model is further described with specific embodiment below in conjunction with accompanying drawing, referring to Fig. 1;
A kind of oil-filtering apparatus; One end of oil filter joint 1 is provided with oil pipe connecting portion 11, the other end and is provided with filter core 2, the middle part that band is made up of skeleton 21 and filter screen 22 and is provided with annular boss 12, and it is characterized in that: the annular boss 12 that said oil is filtered on the joint 1 is provided with annular groove 121 towards the side of filter screen 22.
The cross section of above-mentioned annular groove 121 is rectangular configuration or semicircular structure or half elliptic structure.
Be provided with O-ring seal in the above-mentioned annular groove 121.
Because the said structure of oil-filtering apparatus makes to the utlity model has advantages such as sealing is stable.
The foregoing description is merely the preferred embodiment of the utility model, is not the protection domain that limits the utility model according to this, so: the equivalence that all structures according to the utility model, shape, principle are done changes, and all should be covered by within the protection domain of the utility model.
