Abstract
The invention discloses a sealing mechanism for an oil return hole of an oil tank. The sealing mechanism comprises the oil tank, wherein the oil tank is provided with the oil return hole and an oil return pipe; and the sealing mechanism is arranged between the oil return pipe and the oil return hole. The sealing mechanism is characterized by comprising a base, wherein the lower end of the base extends into the oil return hole. A sealing body is arranged on the base, and the diameter of an inner cavity of the sealing body is adapted with the external diameter of the oil return pipe. The longitudinal middle outer circle of the sealing body is provided with a radial boss of which the cross section is polygonal, and the section of sealing body located under the radial boss extends into the base. An upper conical gap is formed between the upper end of the sealing body and the oil return pipe, and a conical sleeve is arranged in the conical gap. A locking cover is arranged above the conical sleeve, a through hole adapted with the external diameter of the oil return pipe is formed in the top center of the locking cover, the diameter of the inner circle of the locking cover is adapted with that of the outer circle of the section of sealing body located above the radial boss, and the incircle of the locking cover and the radial boss are screwed together in a sealing state. By using the sealing mechanism, rainwater or sewages do not easily enter an oil return tank, so that oil liquid in the oil tank can be prevented from being polluted.
Description
Technical field
The present invention relates to a kind of sealing mechanism.Specifically, it is used to enter between the spill port on fuel tank top board and oil return pipe
The sealing mechanism that row seals.
Background technology
At present, the spill port on fuel tank top board and the sealing between oil return pipe are all to use a rubber cutting ferrule to realize, and see
Fig. 1.Although using rubber cutting ferrule can realize the sealing between spill port and oil return pipe, but owing to rubber cutting ferrule is by glue goods,
Time one is long, and the most aging, elasticity will lose efficacy, thus loses sealing function so that rainwater or dirt are easily accessible oil sump tank,
Fluid in oil sump tank is polluted.
Summary of the invention
The problem to be solved in the present invention is to provide a kind of tank drainback hole sealing mechanism.Use this sealing mechanism, rainwater
Or dirt is not easily accessible oil sump tank, can avoid the fluid in fuel tank is polluted.
The problems referred to above that the invention solves the problems that are realized by techniques below scheme:
The tank drainback hole sealing mechanism of the present invention includes fuel tank, fuel tank top board has spill port, has oil return pipe in spill port, returns
Sealing mechanism is had between oil pipe and spill port.Being characterized in that described sealing mechanism includes base, this base is circular tube shaped, and its lower end is stretched
Enter spill port and the two between in seal shape weld together.Having seal, described seal on base is tubulose, and its inner chamber is straight
Footpath is suitable with oil return pipe external diameter.It is polygonal for having, on the middle cylindrical of seal, the cross section being easy to coordinate with spanner
Radially boss, coordinates in sealing in radially that section of seal under boss stretches into base and between the two.Described seal upper end
And there is up big and down small conical gap between oil return pipe, the taper sheath having up big and down small cylindrical to be taper in conical gap,
The length of taper sheath is more than conical gap.Locking cover, locking Zhao Zhaoding center is had to have and oil return pipe external diameter above taper sheath
Suitable through hole, in locking cover, the cylindrical of that section of seal on circular diameter and radially boss is suitable, locking cover inner circle
All there is screw thread on the cylindrical of that section of seal above and on radial direction boss, be screwed together in sealing shape between the two.
Further improvement of the present invention scheme is, radially that section of seal cylindrical under boss for cone and has outer spiral shell
Stricture of vagina, the inner circle of base is up big and down small cone and has female thread, and radially that section of seal under boss is by outside described
Screw thread and female thread screw in the inner circle of base.
Further improvement of the present invention scheme is, taper sheath and locking cover cover top between have compact heap, compact heap has with
The centre bore that oil return pipe is adaptive, centre bore surrounding has downward chimb, and the lateral surface of this downward chimb is up big and down small cone；
The inside edge, upper end of described taper sheath has chamfering, described downward chimb to stretch in this chamfering.
The further improvement project of the present invention is, the cover top medial surface of described locking cover is up-small and down-big taper surface.
As can be seen from the above scheme, in close in stretching into base due to that section of seal under radial direction boss and between the two
Envelope coordinates.There is up big and down small conical gap between described seal upper end and oil return pipe, have up big and down small in conical gap
The taper sheath that cylindrical is taper, the length of taper sheath be more than conical gap.Locking cover, the cover of locking cover is had above taper sheath
There is the through hole suitable with oil return pipe external diameter at center, top, outside that section of seal on the interior circular diameter of locking cover and radially boss
Circle is suitable, and the cylindrical of that section of seal in locking cover inner circle and on radial direction boss all has screw thread, in sealing between the two
Shape is screwed together.By tightening locking cover, in taper sheath lower end wedging conical gap can be made, make return duct cylindrical and sealing
Gapless between body, so that rainwater or dirt are not easily accessible fuel tank, it is to avoid the fluid in oil sump tank is brought pollution.
Again due to that section of seal cylindrical under radial direction boss for cone and have external screw thread, the inner circle of base be upper greatly
Under little cone and have female thread, radially that section of seal under boss screws in base by described external screw thread and female thread
Inner circle in.By screwing seal, can make between that section of seal under radial direction boss and base inner circle more and more tightr.This
Sample, can eliminate rainwater further or dirt enters fuel tank, it is to avoid the fluid in fuel tank is brought pollution.
Further, since have compact heap between the cover top of taper sheath and locking cover, compact heap has adaptive with oil return pipe in
Central hole, centre bore surrounding has downward chimb, and the lateral surface of this downward chimb is up big and down small cone；Described taper sheath upper
End inside edge has chamfering, described downward chimb to stretch in this chamfering.By tightening locking cover, the wedging of downward chimb lower end can be made to fall
In angle, make gapless between return duct cylindrical and seal, thus further obviate rainwater or dirt enters fuel tank, it is to avoid be right
Fluid in fuel tank brings pollution.
Accompanying drawing explanation
Fig. 1 is the tank drainback hole sealing mechanism schematic diagram of the present invention.
