Problems solved by technology

[0002] The fuel inlet device of the vehicle usually realizes the fuel supply to the vehicle through the connection of the oil pipe and the fuel tank. When the fuel tank cap on the fuel tank is closed, since the existing fuel tank cap is not provided with a non-return device, when the vehicle is running, the vehicle’s Vibration will loosen the rotation direction of the fuel tank cap, especially in bad road conditions, the stability is extremely poor. On the other hand, the current fuel tank cap also lacks the design to prevent excessive rotation, which makes it inconvenient to open the fuel tank cap

Abstract

The invention discloses a fuel tank cap. The fuel tank cap comprises a fuel pipe connector and a fuel tank cap body. A fuel pipe is connected to the bottom of the fuel pipe connector, the fuel pipe connector is provided with a fuel inlet channel, a connection surface is arranged at the top end of the fuel pipe connector, and a fixing groove surrounding the fuel pipe connector by one circle is formed in the outer wall of the fuel pipe connector. The fuel tank cap body comprises a fixing part, a holding part is arranged at the top of the fixing part, the fixing part is arranged on the bottom of the fuel tank cap body and provided with a limiting device, the limiting device comprises a packing block and an anti-rotation block, the packing block and the anti-rotation block are connected, the anti-rotation block is trapezoid and provided with an abutting surface connected to the packing block, and the abutting surface is connected to an inclination surface. According to the invention, the stability of the fuel tank cap is improved effectively, the fuel tank cap is prevented from sliding due to loosening, and the phenomenon that it becomes more difficult to open the fuel tank cap because the fuel tank cap is excessively rotated is prevented.

Description

technical field [0001] The invention relates to a fuel tank cap, in particular to an anti-loosening fuel tank cap. Background technique [0002] The fuel inlet device of the vehicle usually realizes the fuel supply to the vehicle through the connection of the oil pipe and the fuel tank. When the fuel tank cap on the fuel tank is closed, since the existing fuel tank cap is not provided with a non-return device, when the vehicle is running, the vehicle’s Vibration will loosen the direction of rotation of the fuel tank cap, especially in bad road conditions, the stability is extremely poor. On the other hand, the current fuel tank cap also lacks the design to prevent excessive rotation, which makes it inconvenient to open the fuel tank cap. [0003] Therefore those skilled in the art devote themselves to developing a kind of anti-loosening oil tank. Contents of the invention [0004] In view of the above-mentioned defects in the prior art, the technical problem to be solved ...
