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

Embodiment Construction

[0009] The present invention is further described below in conjunction with embodiment and accompanying drawing.

[0010] see figure 1 , figure 2

[0011] The oil tank fill pipe buffer provided by the present invention has a base 1, and the middle part of the base 1 is provided with an opening 1c. The bottom of the base 1 hinges the cover plate 2 through the pin shaft 3 in the following way: the bottom of the base 1 has a pair of bosses 1a, the bosses 1a are integrated with the base 1, the pin shaft 3 passes through the cover plate 2, and the pin shaft The two ends of 3 are fitted in the boss 1a. The pin shaft 3 is equipped with a spring 4, and the two ends of the spring 4 respectively abut against the base 1 and the cover plate 2, and under the action of the spring 4, the cover plate 2 closes the opening 1c.

[0012] see figure 1 , in order to facilitate the installation of this buffer in the oil tank filling pipe, there are more than two mounting holes 1b evenly distri...

Abstract

The invention relates to an oil filling pipe buffer for an automotive oil tank. A through hole is arranged in the middle of a base, the bottom of the base is articulated with a cover plate through a pin shaft which is provided with a spring, and both ends of the spring respectively abut on the base and the cover plate which is used for closing the through hole. The oil filling pipe buffer for the oil tank, which is provided by the invention, is fixed in an oil filling pipe of the oil tank, and fuel oil in the oil tank can only impact on the buffer without impacting the oil tank cover when an automobile immediately brakes or turns a corner so as to further thoroughly avoid an oil leakage phenomenon. When oil needs to fill in the oil tank, the oil tank cover is opened, an oil filling gun extends into the oil filling pipe, the cover plate is pushed inwards by the oil filling gun and turns inwards, the oil filling gun can penetrate through the base for filling oil; and after oil is filled, the oil filling gun is drawn back, and the cover plate can be automatically closed.

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 mode adopted for the closing of the fuel tank nozzle of the automobile fuel tank is: a fuel tank cap is installed at the nozzle of the fuel filler pipe, and its nozzle is sealed 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 exper...
