Tank cover of fuel tank

Abstract

The invention belongs to the technical field of automobile parts, and particularly relates to a tank cover of a fuel tank. The tank cover comprises a shell; and a rotation module is arranged at the top of the shell. By arranging the rotation module on the shell of the tank cover, a rotary rod and a guiding rod in the rotation module apply torque force to the tank cover when being mutually matched,the difficulty of taking down and mounting the tank cover is greatly lowered, meanwhile the tightening effect of the tank cover is enhanced, and engine oil leakage caused by infirm mounting of the tank cover is reduced; and by setting the shape of a limiting block, the limiting block and a clamping groove are mutually matched, on the one hand, torque force to the top of the shell during rotationof the rotary rod is increased, on the other hand, the acting area of the rotary rod on the shell is increased, local damage caused to the shell by concentrated acting force of the rotary rod on the shell is reduced, and thus the screwing-out effect of the rotary rod on the tank cover is enhanced.

Description

technical field [0001] The invention belongs to the technical field of auto parts, in particular to a fuel tank cover. Background technique [0002] The fuel tank cap is a sealing part used to cover the filler port of the fuel tank. When refueling, the tank cap needs to be removed. After refueling, the tank cap needs to be installed and locked at the fuel filler port to seal the fuel tank. Avoid fuel leakage; when refueling the fuel tank, because the fuel tank cover is closely matched with the fuel tank shell, the staff often need to twist the tank cover time-consuming and laboriously to take it out, and when twisting the fuel tank When the tank cover is used, the hands of the staff are often stained with oil due to work, which makes the hands of the staff slip when twisting the tank cover, making it more difficult to take out the fuel tank cover, and after the fuel tank refueling work is completed , the tank cap needs to be manually screwed into the fuel tank cap opening. ...

[0002] The fuel tank cap is a sealing part used to cover the filler port of the fuel tank. When refueling, the tank cap needs to be removed. After refueling, the tank cap needs to be installed and locked at the fuel filler port to seal the fuel tank. Avoid fuel leakage; when refueling the fuel tank, because the fuel tank cover is closely matched with the fuel tank shell, the staff often need to twist the tank cover time-consuming and laboriously to take it out, and when twisting the fuel tank When the tank cover is used, the hands of the staff are often stained with oil due to work, which makes the hands of the staff slip when twisting the tank cover, making it more difficult to take out the fuel tank cover, and after the fuel tank refueling work is completed , the tank cap needs to be manually screwed into the fuel tank cap opening. Due to the limited strength of the operator, it is difficult to tighten the tank cap into the fuel tank, making it difficult for the tank cap to better seal the oil inside the fuel tank. This can easily lead to problems such as oil leakage inside the fuel tank
