Problems solved by technology
However, in practical applications, when the handle of the fuel filler cap is subjected to abnormal external forces, such as unintentionally driven by fingers or subjected to impact or impact, it will drive the valve body to loosen, resulting in leakage and environmental pollution and safety hazards. It will also cause OBD alarm

The invention discloses an impact preventing oil adding port cover. A valve body, a handle cover which is in buckle connection with the valve body, a ratchet wheel and a reset mechanism are included,wherein the ratchet wheel is arranged between the handle cover and the valve body and can achieve the idling function, and the reset mechanism is arranged on the ratchet wheel and drives the handle cover to reset. When the handle cover is stressed anticlockwise, the ratchet wheel does not drive the valve body to rotate, idling is achieved, and when stress disappears, the ratchet wheel drives the handle cover to recover to the initial state through the reset mechanism. When the anticlockwise rotation angle is larger than 90 degrees, the ratchet wheel drives the valve body to reversely rotate. The reset mechanism is additionally arranged on the ratchet wheel, when the handle cover is stressed anticlockwise, the handle cover idles by 90 degrees, the protection function is still achieved whenthe handle cover is subjected to abnormal external force, and after the external force disappears, through actions of a sliding block and a compression spring, the handle cover resets, and the seal state of a seal ring is kept. After the anticlockwise rotation angle is larger than 90 degrees, the ratchet wheel drives the valve body to reversely rotate. The whole operation is simple and fast, and convenience and practicability are achieved.
Description
technical field [0001] The invention relates to the technical field of automobile fuel, in particular to an anti-shock fuel filler cap. Background technique [0002] In the current fuel filler cap, the handle and the valve body are assembled and combined by buckles. When tightening, the handle drives the valve body to rotate clockwise. When the torque increases to the set force value, the ratchet and the cantilever move relative to each other, and the ratchet moves the cantilever to produce There is a sound; when the handle is disassembled, the handle is turned counterclockwise, the ratchet is stuck on the cantilever and no relative movement occurs, and the valve body is opened under the rotation of the handle. However, in practical applications, when the handle of the fuel filler cap is subjected to abnormal external forces, such as unintentionally driven by fingers or subjected to impact or impact, it will drive the valve body to loosen, resulting in leakage and environmen...
