Description
Technical field
The utility model relates to fuel tank technical fields, and in particular to a kind of fuel oil box pouring orifice sealing device.
Background technique
Plastic fuel tank is because its is light-weight, will not get rusty, the development cycle is short, and it can effectively prevent oily infiltration, in fuel tank
Fuel tank explosion can be prevented when high temperature, have many advantages, such as better security and stability, thus plastic fuel tank gradually replaces metallic oil tank
Fuel oil box as automobile.
Oil filler position setting on its fuel oil box of different automobiles is not quite similar, the oil filler setting of some fuel oil boxes
On the side wall of fuel tank.It is generally covered with trim outside the fuel tank cap of vehicle fuel fuel tank, fuel tank cap passes through rope and trim
Connection.When refueling to fuel oil box, fuel tank cap is removed, fuel tank cap is hung on trim by rope.It uses for a long time, rope
May fracture, fuel tank cap is separated with trim when oiling, thus be may cause Oil supplier and is forgotten to cover fuel tank cap.Fuel tank cap
Do not cover and may cause following problem: (1) in vehicle traveling process, especially road bump when, oil in fuel tank may be from adding
It is overflowed in hydraulic fluid port；(2) sealed between trim and automobile bad, extraneous dust or a small amount of rainwater may by oil filler into
Enter in fuel tank, to influence the quality of fuel oil.
Utility model content
The utility model is intended to provide a kind of sealing device, at the oil filler for plastics fuel oil box, can prevent fuel tank
Interior oil is overflowed from oil filler.
In order to achieve the above objectives, the utility model adopts the following technical solution: fuel oil box pouring orifice sealing device,
The side of plastic fuel tank is equipped with oil filling pipe, and one end of oil filling pipe is located in plastic fuel tank, and the other end of oil filling pipe is located at plastic oil
Outside case, oil filling pipe is located at one end outside plastic fuel tank equipped with oil filler；The sealing element one of sealing oil filler is equipped in oil filling pipe, it should
Sealing element one includes several fan-shaped sealing flaps, and sealing flap is end to end to surround annular, each sealing flap and oiling inside pipe wall
Between be installed with pressure spring, and each sealing flap can be rotated relative to oiling inside pipe wall to the direction far from oil filler.
In above-mentioned technical proposal, when oil filler does not cover fuel tank cap, which can be sealed oil filler, prevent
Only the fuel oil in fuel tank is overflowed from oil filler；Prevent extraneous dust or a small amount of rainwater from entering fuel tank by oil filler simultaneously
It is interior, improve safety.Sealing element one is surround by several fan-shaped sealing flaps and is formed, when being thus inserted into refueling nozzle, each sealing
Valve is separated to open oil filler, and being arranged does not influence normally to refuel after the sealing device.Pressure spring after extracting refueling nozzle for making to seal
Valve resets.
Further, sealing flap is made of corrosion resistant rubber material, and sealing flap is additionally provided with sector far from one end of oil filler
Support frame, the support frame and pressure spring are affixed.
Rubber material is softer, and support force is bad, when automobile bumpiness severity, liquid level of fuel oil in fuel tank to the impact force of sealing flap more
Greatly, fuel oil may be from light percolation between two sealing flaps；The support force that sealing flap can be improved after support frame is set, avoids firing
Oil permeates from oil filler.
Further, the sealing element two of annular is additionally provided between sealing element one and oiling inside pipe wall, sealing element two, which is fixed in, to be added
On tube inner wall, sealing element one and sealing element two are affixed, and sealing element two is equipped with seal section, close on sealing element two when oiling
The outer wall forming face for sealing section and refueling nozzle seals.
Since sealing element one is made of the sealing flap of several sectors, after being inserted into refueling nozzle, each sealing flap separation, Mei Gemi
There is gap between sphragis and sealing flap, so that refueling nozzle is only capable of and forms linear sealing at the periphery of sealing element one.Sealing element is set
After two, when oiling, the outer wall forming face of seal section and refueling nozzle on sealing element two is sealed, and thus improves refueling nozzle in oil filler
The sealing effect at place.
Further, sealing element two is whole is made of rubber material, and seal section is obliquely installed, and big end is located at the one of oil filler
End.
A kind of structure of sealing element two, as seen from the outside inward, seal section is in the shape of a trumpet for such structure, so that sealing element
Two to far from oil filler direction rotation after can be in close contact with the outside wall surface of refueling nozzle, forming face seal.
Further, sealing element two includes the support ring being fixed on oiling inside pipe wall, and support frame turns with the support ring
Dynamic connection；Support ring is equipped with rubber layer, and seal section is located in rubber layer and the seal section is parallel to the center line of oil filling pipe and sets
It sets.
Another structure of sealing element two is supported compared with sealing element two is full rubber structure by setting support ring
Rubber layer avoids the bending deformation of sealing element two, to improve the service life of sealing element two.
Further, the baffle being made of two semicircular sub- baffles, sub- baffle and oil filling pipe pipe are additionally provided in oil filling pipe
Wall rotation connection, is equipped with sealing element three made of rubber between the periphery and oiling inside pipe wall of sub- baffle, sealing element three is affixed
On sub- baffle；The side of support frame is aligned with sealing flap, and to be aligned side, the another side of support frame is embedded in sealing
In valve；The end face of sub- baffle is rotatably connected to connecting rod, and the other end of connecting rod is rotatablely connected with side is aligned；When oiling,
Two sub- baffles are back-to-back.
After being inserted into refueling nozzle, while refueling nozzle makes each sealing flap separate and rotate, make sub- flapper, is refueled with opening
Mouthful, make sub- flapper without additional power.The structure that baffle prevents liquid level of fuel oil in fuel tank overflow as first again, sealing element one
As the structure of the second weight anti-overflow, the structure of the double-deck anti-overflow, anti-overflow effect is more preferable, and reliability is higher.Otherwise sealing element
One as first prevents external dust and rainwater from entering the structure in fuel tank again, and baffle prevents external dust and rain as second again
Water enters the structure in fuel tank.
Further, sub- baffle with a thickness of 0.5mm~2mm.The thickness of sub- baffle is smaller, to the flow velocity of oiling substantially without shadow
It rings.
Further, the quantity of sealing flap is four, and sealing flap is in arc-shaped close to the end face of oil filler；When oiling, four
The end face of sealing flap is integrally rounded.Keep the outer wall compactness of sealing flap and refueling nozzle higher.
