Embodiment Construction
[0018] combine Figure 1 to Figure 2 The fuel tank cap with the function of prompting for tightening of the present invention will be further described.
[0019] A fuel tank cap with a tightening prompt function is characterized in that it includes an upper cover 1 , a spring 3 , a turntable 2 , a positioning chuck 4 and a lower cover 5 . The upper cover 1 is covered on the upper opening of the lower cover 5 and can rotate relative to the lower cover 5 , while a space for the turntable 2 and the positioning chuck 4 is formed between the upper cover 1 and the lower cover 5 . The inner wall of the upper cover 1 has an upper limit block 13, and the outer wall of the lower cover 5 has two lower limit blocks 52, and the upper limit block 13 is located between the two lower limit blocks 52 to limit the relative position of the upper cover 1. The angle of rotation of the lower cover 5. The positioning chuck 4 is installed in the lower cover 5 in a circumferential limit, and the inn...

The invention discloses an oil tank cover with a tightening prompt function. The oil tank cover comprises an upper cover, a spring, a turntable, a positioning chuck and a lower cover; wherein the upper cover covers the upper opening of the lower cover, an upper limiting block is arranged in the upper cover, and a lower limiting block matched with the upper limiting block is arranged on the lower cover; the positioning chuck is peripherally limited and mounted in the lower cover, the lower end of the turntable is provided with sounding ratchets, the positioning chuck is provided with an elastic sounding pawl, the sounding ratchets and the elastic sounding pawl are matched to form a one-way rotating structure of the turntable, and after the sounding ratchets rotate relative to the elastic sounding pawl, the elastic sounding pawl impacts the sounding ratchets to generate a warning tone; a linkage ratchet is arranged in the upper cover, a linkage pawl is arranged on the turntable, and the linkage ratchet is matched with the linkage pawl; and the spring is arranged between the upper cover and the positioning chuck. The oil tank cap screwing prompting device has a screwing prompting function, so that after the oil tank cap is screwed in place, a clicked prompt sound is generated and the oil tank cap cannot be screwed continuously; therefore, it is conveniently known that the oil tank cap is in a screwed state.
Description
technical field [0001] The invention relates to the technical field of fuel tank accessories, and more specifically relates to a fuel tank cap. Background technique [0002] The fuel tank cap of the car is the cover of the fuel tank used to store gasoline on the car. At present, all the fuel tank caps on the market have the function of tightening the sound, that is, in the process of tightening the fuel tank cap after refueling, after a certain angle of rotation, the fuel tank cap will emit a sound to indicate that the fuel tank cap has been tightened. [0003] During the tightening process of the traditional fuel tank cap, the beeping sound can be continuously emitted. Even after tightening, if the fuel tank cap is tightened, the beeping sound will continue to be emitted. Therefore, when some operators tighten the fuel tank cap, they don't know how many noises it takes to lock it, which causes the operator to continue to twist the fuel tank cap.
