Description
Technical field
The utility model relates to a kind of automotive oil tank, specifically a kind of automotive oil tank drain oil hermetically-sealed construction.
Background technology
At present the bottom of the automotive oil tank that generally uses has a drain oil, but has the hermetically-sealed construction of open and close at the drain oil place, and the regular drain oil of opening can be discharged the sump oil in the fuel tank.Constituting of existing fuel tank drain oil hermetically-sealed construction: the inboard of bottom half drain oil is fixed with nut, and a plug screw that passes drain oil connects with nut, is provided with grommet type seals and ring washer successively between the bottom half outside and plug screw.The shortcoming that existing this drain oil hermetically-sealed construction exists is: leak tightness is not good enough, behind the repeated use, oil leakage phenomenon is arranged.
The utility model content
The purpose of this utility model is to provide a kind of automotive oil tank drain oil hermetically-sealed construction, the good airproof performance of sealing structure, and behind the repeated use, still can the failure-free sealing.
For achieving the above object, the utility model adopts following scheme: automotive oil tank drain oil hermetically-sealed construction, the inboard of bottom half drain oil is fixed with nut, one plug screw that passes drain oil connects with nut, be provided with seal ring and packing ring successively between the bottom half outside and plug screw, the bottom of seal ring has boss, and the edge of packing ring has the upwards flange of bending, packing ring encases seal ring, and the boss on the seal ring is in the through hole of packing ring.
By such scheme as seen, in the automotive oil tank drain oil hermetically-sealed construction that the utility model provides, by seal ring being encased by packing ring, by plug screw packing ring and seal ring are clamped again, can make and form better seal between seal ring and the bottom half and between seal ring and the plug screw, even behind repeated use,, still can realize better seal to drain oil by closely cooperating between seal ring, packing ring and plug screw.
The utility model is rational in infrastructure, reliable, its good airproof performance, and long service life.
Description of drawings
Accompanying drawing is the structural representation of the utility model one embodiment.
The specific embodiment
Further specify the utility model below in conjunction with embodiment and accompanying drawing.
Referring to accompanying drawing
The automotive oil tank drain oil hermetically-sealed construction that the utility model provides is: the inboard of casing 1 bottom drain oil 1a is fixed with nut 2, one plug screw 5 that passes drain oil connects with nut 2, between casing 1 bottom outside and plug screw 5, be provided with seal ring 4 and packing ring 3 successively, the bottom of seal ring 4 has boss 4a, the edge of packing ring 3 has the upwards flange 3a of bending, packing ring 3 encases seal ring 4, and the boss 4a on the seal ring 4 is in the through hole of packing ring 3.By accompanying drawing as seen, after plug screw 5 screwed, compressing seal ring 4 and packing ring 3 can be realized the drain oil better seal is pulled down plug screw 5, can discharge sump oil in the casing 1 by drain oil 1a
In addition, seal ring 4 adopts oil proof rubbers, to the technical requirements of seal ring is: hardness HS80 ± 5, anti-gasoline, diesel fuel characteristics are good, high temperature resistant 200 ± 5 ℃.
