Oil filling pipe buffer for automobile oil tank

Abstract

According to an oil filling pipe buffer for an automobile oil tank, a through opening is formed in the middle of a base, a cover plate is hinged to the bottom of the base through a pin shaft, a springis installed on the pin shaft, two ends of the spring abut against the base and the cover plate respectively, and the through opening is sealed by the cover plate. The oil tank oil filling pipe buffer is fixed in an oil tank oil filling pipe; when an automobile is braked emergently or turns, the fuel oil in an oil tank only impacts the buffer and cannot impact an oil tank cover, and then the oilseepage phenomenon can be thoroughly avoided. When oil needs to be filled into the oil tank, the oil tank cover is opened, an oil filling gun stretches into the oil filling pipe, the cover plate is pushed inwards by the oil filling gun, the cover plate can be then overturned inwards; the oil filling gun can penetrate through the base to add oil, after oil adding is completed, the oil filling gun is pulled out, and the cover plate can be closed automatically.

Description

technical field [0001] The invention relates to a buffer device installed in a filling pipe of an automobile fuel tank. Background technique [0002] At present, the adopted mode of the closing of the fuel tank nozzle of the automobile fuel tank is: a fuel cap is installed at the nozzle of the fuel filler pipe, and its nozzle is closed by the cooperation of the fuel tank cap and the fuel filler pipe. In the prior art, only relying on the fuel tank cap to seal the filling pipe, the defect is: when the car brakes suddenly or turns, the fuel in the fuel tank will often impact the fuel tank cap, and the tightness of the cooperation between the fuel tank cap and the filling pipe is insufficient. Under the best conditions, there will often be fuel leakage, especially after repeated refueling, the fuel tank cap has been removed and installed from the fuel filler pipe many times, and after a certain amount of wear and tear, the fuel tank cap and the fuel filler pipe will experience ...

Problems solved by technology

In the prior art, only relying on the fuel tank cap to seal the filling pipe, the defect is: when the car brakes suddenly or turns, the fuel in the fuel tank will often impact the fuel tank cap, and the tightness of the cooperation between the fuel tank cap and the filling pipe is insufficient. Under the best conditions, there will often be fuel leakage, especially after repeated refueling, the fuel tank cap has been removed and installed from the fuel filler pipe many times, and after a certain amount of wear and tear, the fuel tank cap and the fuel filler pipe will experience oil leakage. will be more serious
