Abstract
The utility model discloses an oil-filling pipe for an automobile oil tank. The oil-filling pipe comprises an oil-filling pipe body. One side of the oil-filling pipe body is connected with an air ventilation pipe. The oil-filling pipe is characterized in that an oil cup arranged in the oil-filling pipe body is arranged on a pipe opening of the air ventilation pipe, the bottom of the oil cup is provided with a center through hole matched with an oil-filling gun, and the diameter of the center through hole is smaller than the diameter of an inner hole in the oil-filling pipe body. The oil cup is arranged on the original oil-filling pipe, the oil cup is arranged above the air ventilation pipe, the oil cup can fix a position of the oil-filling gun when oil is filled, and prevents the arrangement position of the oil-filling gun from getting too close to the air ventilation pipe of the oil-filling pipe, influencing ventilation of the air ventilation pipe, and leading to frequent breakage of the gun during oil-filling process. When the oil is filled, as the oil-flow speed in the oil-filling pipe is fast, phenomena of oil splashing and spraying probably occur, and the oil cup above the air ventilation pipe can effectively prevent the oil from splashing outside the oil-filling pipe.
Description
Technical field
The utility model relates to the automotive oil tank structure.
Background technology
Fuel filler pipe on the fuel tank of vehicle fuel system is with the parts of fuel delivery in the fuel tank when being used for fuel filling.Smooth and easy when fuel filler cap need guarantee fuel filling, when fuel filling speed is (30 ~ 60) L/min, the phenomenon that fuel oil does not have and outwards sprays.Complicated for realizing the structure that the existing fuel filler pipe of above function adopts; Like the patent No. 201020680057.8 disclosed " the anti-outer device that spatters of motor vehicle oil tank fuel filler pipe "; It is above the fuel filler pipe Center Vent tube, to increase parts such as oil proof rubber elastic body, sleeve pipe, guide hole, conduit; Fuel oil splashes in and has increased more part on the former fuel filler pipe when preventing to refuel, and the complex structure cost is high." a kind of fuel filler pipe " of the patent No. 201020594595.5 is above the fuel filler pipe Center Vent tube, to increase baffle, aditus laryngis assembly etc. for realizing this function, need squeeze out inside hemispherical projections on the fuel filler pipe, increased part Fabrication procedure, and cost is higher.
The utility model content
The technical matters that the utility model will solve provides the fuel filler pipe on a kind of automotive oil tank, and with simple structure, fuel oil improves the purpose of fuel filling smoothness from the oil filling port ejection when being able to prevent fuel filling.
The technical scheme of the utility model is following:
Fuel filler pipe on a kind of automotive oil tank, it has the fuel filler pipe body, is connected with breather pipe in a side of fuel filler pipe body; In the fuel filler pipe body, be provided with lubricating cup, said lubricating cup is positioned at the mouth of pipe top of breather pipe, and the central through hole that cooperates with nozzle is arranged at the lubricating cup bottom, and the diameter of central through hole is less than the diameter of fuel filler pipe body endoporus.
On the cup end of said lubricating cup or the sidewall air extractor vent is arranged, the cup-shaped of lubricating cup dwindled from top to bottom gradually, and air extractor vent is opened on the inclined-plane of lubricating cup by the sidewall of bottom.
Said lubricating cup adopts and the integrated structure of fuel filler pipe body, or an independent cup, is welded in the fuel filler pipe body.
The utility model has increased lubricating cup on former fuel filler pipe basis; Lubricating cup is positioned at breather pipe top, and the fixing nozzle position of placing of lubricating cup prevents that breather pipe is too near on nozzle placement location and the fuel filler pipe during fuel filling; Influence the breather pipe ventilation, the frequent rifle of jumping when causing fuel filling.When fuel filling, because fuel flow rate is big in the fuel filler pipe, phenomenons such as fuel oil splashes, oil spout possibly appear, the lubricating cup of breather pipe top can also prevent effectively that fuel oil is splashed to outside the fuel filler pipe.
Therefore, compared with prior art, the utility model fuel filler pipe can prevent effectively that fuel oil from splashing, being ejected into outside the fuel filler pipe, improve to refuel smoothness, and structure, makes simply, and cost is low.
Description of drawings
Fig. 1 is the utility model fuel filler pipe structural representation
Fig. 2 is the utility model fuel filler pipe cutaway view
Fig. 3 is a lubricating cup scheme drawing in the utility model fuel filler pipe
Fig. 4 is that the utility model fuel filler pipe cooperates scheme drawing with lubricating cup.
Among the figure, the 1st, breather pipe, the 2nd, lubricating cup, the 3rd, fuel filler pipe, the 4th, nozzle.2-1 is the lubricating cup air extractor vent, and 2-2 lubricating cup central through hole, 2-3 are the lubricating cup outer walls, and 2-4 is the lubricating cup inclined-plane; 3-1 is the fuel filler pipe inclined-plane.
The specific embodiment
Below in conjunction with the accompanying drawing and the specific embodiment the utility model is done further explain:
Referring to Fig. 1, with Fig. 2, this fuel filler pipe has fuel filler pipe body 3, is connected with breather pipe 1 in a side of fuel filler pipe body, in the fuel filler pipe body, is provided with lubricating cup 2.The same with existing structure, fuel filler pipe 3 is to become diameter tube, and its diameter becomes stepped appearance to change from the fuel filler pipe oral area, and maximum gauge is b, and the diameter c of lubricating cup outer wall 2-3 is identical with size b.Lubricating cup is put into fuel filler pipe, and through fuel filler pipe inclined-plane 3-1 on the fuel filler pipe 3,2-3 cooperates with the lubricating cup outer wall, and the restriction lubricating cup is put into the degree of depth, guarantees that lubricating cup is higher than the mouth of pipe of breather pipe 1.The cup-shaped of lubricating cup 2 dwindled from top to bottom gradually, and the central through hole 2-2 that cooperates with nozzle is arranged at the lubricating cup bottom, and air extractor vent 2-1 is arranged on the sidewall.After lubricating cup 2 was in place in fuel filler pipe 3, lubricating cup outer wall inclined-plane 2-4 and fuel filler pipe inwall inclined-plane 3-1 were angled the angle of e, guaranteed that lubricating cup air extractor vent 2-1 can not blocked by fuel filler pipe inclined-plane 3-1.Lubricating cup is through welding manner and fuel filler pipe fixation.
During fuel filling, nozzle 4 is put into the central through hole 2-2 of lubricating cup, and the lubricating cup central through hole is big than nozzle.Can limit nozzle 4 through the lubricating cup central through hole and in fuel filler pipe 3, arbitrarily rock, guarantee between nozzle and the breather pipe apart from a, prevent to cause refueling and have some setbacks because of nozzle stops up breather pipe.Ventilation smoothness when 4 air extractor vent 2-1 on the lubricating cup 2 can guarantee fuel filling simultaneously.
During fuel filling, the fuel oil major part of splashing is blocked by lubricating cup 2, can from fuel filler pipe 3, not sputter, and influences the safety of fuel filling.Owing on the lubricating cup 2 air extractor vent 2-1 is arranged; The fuel oil that splashes also possibly sputtered from fuel filler pipe 3 by this place; Therefore with lubricating cup air extractor vent 2-1 open lubricating cup 2 lean on the bottom sidewall the inclined-plane on; Reduce lubricating cup air extractor vent 2-1 and project to the area of conter on the fuel filler pipe line of centers vertical surface, thereby reduce fuel oil is splashed to fuel filler pipe 3 outsides from lubricating cup air extractor vent 2-1 probability.
