Abstract
The utility model discloses a high strength plastics oil tank, personally experience sth. Part of the body and locate jar pump body at body top, its characterized in that including open jar of top: the round slot has been seted up at the top of the jar body, the ditch inslot is equipped with the sealing washer, sealing washer interference fit is between the slot and the pump body, the slot undercut forms a plurality of spacing holes, be equipped with the spacing boss with spacing hole matched with on the sealing washer. The utility model discloses structural strength height, anti falling and anticollision nature preferred, sealed effectual beneficial effect have.
Description
Technical field
The utility model relates to a kind of oil tank, specifically a kind of highstrenghtpiston's oil tank.
Background technique
The long-pending oil tank of current onboard hydraulic system uses aluminum casting mostly, is connected with the pump housing by screw.There is the defect such as pore, burning into sand hard spot in this kind of structure, the problem that sealing is poor simultaneously, cost is high.Patent CN203453153U discloses a kind of plastic oil tank, adopts asymmetrical thread pore structure, is convenient to assemble centering, thus improves sealing.But when colliding, screw and tapped hole easily occurring gap, causing leaking oil condition and occurring, therefore anti-fall with crashworthiness not good.
Model utility content
The purpose of this utility model is the deficiency existed to solve above-mentioned background technology, proposes that a kind of structural strength is high, anti-falls highstrenghtpiston's oil tank that is better with crashworthiness, good sealing effect.
In order to realize above object, a kind of highstrenghtpiston's oil tank that the utility model provides, comprise the tank body of open-topped and be located at the pump housing at tank body top, it is characterized in that: the top of described tank body offers a circle groove, seal ring is provided with in described groove, described seal ring interference fit is between groove and the pump housing, and described groove is recessed to form multiple spacing hole downwards, and described seal ring is provided with the positive stop lug boss matched with spacing hole.
As preferred version of the present utility model, described tank body is cube, and the position of the corresponding tank body edges and corners of described groove is recessed to form spacing hole downwards, and described seal ring is provided with the positive stop lug boss matched with spacing hole.
Further, the junction surface of described tank body and the pump housing is provided with multiple tapped hole, is provided with from top to bottom through the screw of the pump housing in the described pump housing, and described tank body and the pump housing close fixing by screw and corresponding threaded holes.
Closer, described seal ring extends the annular boss enclosed around tapped hole outer one.
Again further, at least one waling is provided with between two of the described tank body mutual inwalls opposed.
The beneficial effects of the utility model: one, by setting up the structure of seal ring between tank body and the pump housing, improve overall tightness; Its two, matched with the positive stop lug boss of seal ring by the spacing hole of groove, make seal ring collide time be not easy, improve structural strength; Its three, seal ring extends the annular boss enclosed around tapped hole outer one, makes seal ring also can wrap screw, further increase sealing, the possibility of leakage of oil occurs when reducing collision.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is ring structure schematic diagram;
Fig. 3 is tank body side view;
Fig. 4 is tank body plan view;
In figure: tank body 1, groove 1.1, spacing hole 1.2, tapped hole 1.3, seal ring 2, positive stop lug boss 2.1, annular boss 2.2, the pump housing 3, screw 4, waling 5.
Embodiment
Below in conjunction with drawings and Examples, the utility model is described in further detail.
Embodiment: as shown in Figures 1 to 4, a kind of highstrenghtpiston's oil tank, comprises the tank body 1 of open-topped and is located at the pump housing 3 at tank body 1 top.Described tank body 1 is cube, and the top of tank body 1 offers a circle groove 1.1, is provided with seal ring 2 in groove 1.1, and seal ring 2 interference fit is between groove 1.1 and the pump housing 3.The position of groove 1.1 corresponding tank body 1 edges and corners is recessed to form spacing hole 1.2 downwards, and described seal ring 2 is provided with the positive stop lug boss 2.1 matched with spacing hole 1.2.
Tank body 1 is provided with multiple tapped hole 1.3 with the junction surface of the pump housing 3, and be provided with in the pump housing 3 from top to bottom through the screw 4 of the pump housing 3, described tank body 1 and the pump housing 3 match fixing by screw 4 and tapped hole 1.3.Seal ring 2 extends the annular boss 2.2 around tapped hole 1.3 outer one circle.Two walings 5 are provided with between two inwalls mutually opposed of tank body 1.
The utility model, by setting up the structure of seal ring 2 between tank body 1 and the pump housing 3, improves overall tightness.Matched with the positive stop lug boss 2.1 of seal ring 2 by the spacing hole 1.2 of groove 1.1, making seal ring 2 be not easy when colliding, improve structural strength, making this highstrenghtpiston oil tank to be inverted installation, internal pressurization fuel feeding simultaneously.Seal ring 2 extends the annular boss 2.2 enclosed around tapped hole outer one, make seal ring 2 also can wrap screw 4, further increase sealing, the possibility of leakage of oil occurs when reducing collision.Waling 5 further enhances tank body 1 structural strength, reduces tank body 1 when colliding and the possibility of deformation occurs.
The above is only preferred embodiment of the present utility model, not does any pro forma restriction to the utility model structure.Every above embodiment is done according to technical spirit of the present utility model any simple modification, equivalent variations and modification, all still belong in the scope of the technical solution of the utility model.
