Abstract

The utility model discloses an anti-blocking device for an oil filling pipe of a gasoline car. The anti-blocking device for the oil filling pipe of the gasoline car comprises an oil filling pipe and an exhaust pipe, wherein an outlet of the exhaust pipe is communicated with an oil filling opening position of the oil filling pipe, and the exhaust pipe is provided with an expansion cavity. According to the anti-blocking device for the oil filling pipe of the gasoline car, the expansion cavity is arranged in the middle of the exhaust pipe, when the exhaust pipe goes into an oil body, the expansion cavity plays a buffering role, gas can pass through the expansion cavity smoothly, and the oil body is reserved in the expansion cavity. The oil body is prevented from spraying out of the exhaust pipe, and smooth flow of oil into an oil tank is ensured.

Description

A kind of oil filling pipe of gasoline motor car preventing clogging up device

Technical field

The utility model relates to the parts of gasoline car, relates in particular to a kind of oil filling pipe of gasoline motor car preventing clogging up device.

Background technology

Along with the development of gasoline car research and development manufacturing, gasoline car car load and each component capabilities are required further to improve, its quality and safety more and more come into one's own, and also day by day seem important for energy savings, minimizing exhaust emission simultaneously.Seek more reasonable, safer property, the high quality parts of tenable environment impact more, this is one of the applicant's content of endeavouring to study always.

Oil filling pipe of gasoline motor car of the prior art, for oil body enters fuel tank smoothly, freeing pipe is discharged the gas in the fuel tank, but sometimes because the oil in the fuel tank too much impacts in the freeing pipe, causes exhaust to have some setbacks, and the oil in the freeing pipe is sprayed from exhausr port.

Summary of the invention

Goal of the invention: the purpose of this utility model is for the deficiencies in the prior art, provide a kind of can the buffering exhaust pipe in oil body, prevent the oil filling pipe of gasoline motor car preventing clogging up device that oil body sprays from freeing pipe.

In order to realize the foregoing invention purpose, the technical scheme that the utility model adopts is:

A kind of oil filling pipe of gasoline motor car preventing clogging up device comprises fuel filler pipe and freeing pipe, and the outlet of described freeing pipe is connected with the oil filling port place of fuel filler pipe and communicates, and described freeing pipe is provided with expansion chamber.Expansion chamber is arranged on the middle part of freeing pipe, and when in the freeing pipe during oil-feed, expansion chamber plays buffer action, and gas is discharged smoothly, prevents that oil body from spraying from freeing pipe, guarantees that oil body adds fuel tank smoothly.

Freeing pipe is inserted at the two ends of described expansion chamber, is provided with the O RunddichtringO between expansion chamber and the freeing pipe, passes through locked clip device between expansion chamber and freeing pipe.

Freeing pipe is inserted at the two ends of described expansion chamber, is provided with the O RunddichtringO between expansion chamber and the freeing pipe, locks by hoop between expansion chamber and freeing pipe.

Described expansion chamber and freeing pipe are integral type.Adopt one-body moldedly, improved the rate of coming into force, reduced productive costs.

The utility model compared with prior art, its beneficial effect is: expansion chamber is arranged on the middle part of freeing pipe, when freeing pipe enters oil body, expansion chamber plays buffer action, and gas passes through smoothly, and oil body within it section retains, avoid oil body from freeing pipe, to spray, guaranteed oily smooth inflow fuel tank; Expansion chamber is connected with gas-distribution pipe by O RunddichtringO, clip or hoop, can make freeing pipe and expansion chamber adopt different materials processing, is convenient to expansion chamber and is processed into difformity with applicable different installing spaces; Expansion chamber and freeing pipe are integral type, adopt one-body moldedly, have improved the rate of coming into force, and have reduced productive costs.
