Description

Is furnished with the oil filling port of extension pipe

Technical field

The utility model belongs to the technical field of improvement of fuel tank for automobile.

Background technology

The fuel tank of automobile at the design initial stage in order to not affect the assembling of other device or attractive in appearance, general design shorter, even if the oil filling port of high capacity waggon, by the impact that car body is huge in refueling process, stop at nozzle length just in time also relatively bothersome, meanwhile, because this body length of oil filling port is shorter, the oil pressure of nozzle is higher again, in initial moment of refueling, fuel fouling phenomenon will be produced, not only waste the energy, also cause danger factor.Once vehicle fuel quantity exhausts, when cannot travel to petrol service station, extension pipe also facilitates chaufeur oil drum to refuel.

Summary of the invention

The purpose of this utility model is by how original oil filling port improves, and inserts the oil filling port being furnished with extension pipe that extends oil filling port length in inside.

The utility model is made up of oil filling port and extension pipe, and it is inner that extension pipe inserts oil filling port;

At the spacing upper frame of extension pipe of the oriented inner process of the neck of oil filling port, there is the spacing underframe of the extension pipe caved inward bottom, and oil filling port sidewall has fuel tank refueling unit pore;

The extension pipe oil filling port place of extension pipe upper end has aduncate extension pipe to keep off oil box, the outer wall of extension pipe has the slideway that upper frame spacing with extension pipe is corresponding, slideway is divided into the spacing slideway of longitudinal extension pipe, extension pipe dismounting slideway with transverse direction and is communicated with the sideslip road of the spacing slideway of extension pipe, extension pipe dismounting slideway, the spacing slideway bottom of extension pipe is extension pipe pull lower limit card, and the spacing slideway top of extension pipe is extension pipe pull upper limit card;

In oil filling port interior lower end, extension pipe filter screen is installed.

The utility model structure is simple, easy to install.Owing to increasing an extension tube in original oil filling port, the oily length contacted with bottom is increased like this at refueling process, fuel fouling phenomenon can not be produced, when vehicle fuel quantity exhausts, when cannot travel to petrol service station, extension pipe also facilitates chaufeur oil drum to refuel, and extension tube can pull and push, namely can pull out, also can retraction, like this when not using and original oil filling port substantially completely the same, do not affect the assembling of other device of car or attractive in appearance.

Detailed description of the invention

The utility model is made up of oil filling port 2 and extension pipe 7, and it is inner that extension pipe 7 inserts oil filling port 2;

Oil filling port 2 is exactly the oil filling port on original car, and the utility model is to coordinate extension pipe 7 of the present utility model to transform on its original base.And extension pipe 7 is in order to reach the purpose of this utility model and effect carries out independent design.

At the spacing upper frame 1 of the extension pipe of the oriented inner process of the neck of oil filling port 2, there is the spacing underframe 3 of the extension pipe caved inward bottom, by having fuel tank refueling unit pore 4 on oil filling port 2 sidewall; Deflation hole 4 is conveniently discharged by the gas of fuel tank internal in refueling process.

Extension pipe oil filling port 6 place of extension pipe 7 upper end has aduncate extension pipe to keep off oil box 5, the outer wall of extension pipe 7 has the slideway corresponding with the spacing upper frame of extension pipe 1, slideway is divided into the spacing slideway of longitudinal extension pipe 8, extension pipe dismounting slideway 10 with transverse direction and is communicated with the sideslip road 12 of the spacing slideway 8 of extension pipe, extension pipe dismounting slideway 10, extension pipe spacing slideway 8 bottom is extension pipe pull lower limit card 9, and extension pipe spacing slideway 8 top is extension pipe pull upper limit card 11; Extension pipe pull lower limit card 9 and extension pipe pull upper limit card 11 carry out restriction extension pipe 7 up-and-down movement stroke.

Be provided with extension pipe filter screen 13 in oil filling port 2 interior lower end, extension pipe filter screen 13 enters fuel tank internal containing impurity in the oil preventing from adding.

During oiling, first extension pipe 7 is pulled out, due to non rotating extension pipe 7, so the spacing upper frame of extension pipe 1 only slides when reaching bottom extension pipe pull lower limit card 9 and blocks in the spacing slideway 8 of extension pipe, now nozzle is placed in extension pipe oil filling port 6 and refuels, due to the design of extension pipe gear oil box 5, when oil touches the wall of extension pipe oil filling port 6, even if can sputtering be produced, also can be extended pipe gear oil box 5 to block, be unlikely to be splashed to outside.After oil adds, extension pipe is retracted in oil filling port, now because extension pipe card is gone up by the existence of extension pipe pull upper limit card 11 in position.

When needs keep in repair separately oil filling port or extension pipe, as long as pull-out extension pipe 7, then extension pipe is rotated along sideslip road 12, pull on extension pipe, like this, extension pipe on oil filling port 2 spacing upper frame 1 successively along the spacing slideway 8 of extension pipe, sideslip road 12 and extension pipe dismounting slideway 10, finally can be extracted out from extension pipe dismounting slideway 10 bottom, is extracted out by extension pipe and namely can take out extension pipe.

The design of the spacing underframe 3 of extension pipe is after extension pipe 7 inserts oil filling port 2 inside, carries out spacing, in order to safer, be just provided with the spacing underframe 3 of this extension pipe although can be mated with the spacing upper frame of extension pipe 1 by extension pipe pull upper limit card 11.
