fig. 2 is another exploded perspective view of the fuel tank cap with the tightening prompting function according to the present embodiment.
Detailed Description
The fuel tank cap with tightening prompting function according to the present invention will be further described with reference to fig. 1 to 2.
The utility model provides a fuel tank cap with screw up prompt facility, characterized by: comprises 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, and a space for installing the rotary table 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 is provided with an upper limiting block 13, the outer side wall of the lower cover 5 is provided with two lower limiting blocks 52, and the upper limiting block 13 is positioned between the two lower limiting blocks 52 to limit the rotation angle of the upper cover 1 relative to the lower cover 5. The positioning chuck 4 is circumferentially limited and mounted in the lower cover 5, the inner side of the lower end of the rotary disc 2 is circumferentially provided with sounding ratchets 21, the positioning chuck 4 is provided with elastic sounding pawls 41, and the sounding ratchets 21 and the elastic sounding pawls 41 are matched to form a one-way rotating structure of the rotary disc 2, namely, the rotary disc can rotate relative to the positioning chuck in a clockwise direction and cannot rotate in an anticlockwise direction; after the sounding ratchet 21 is rotated relative to the elastic sounding pawl 41, the elastic sounding pawl 41 hits the sounding ratchet 21 to generate a warning sound. The upper cover is characterized in that a linkage ratchet 11 is arranged in the upper cover 1, a linkage pawl 23 is arranged on the rotary table 2, the linkage ratchet 11 is matched with the linkage pawl 23 to drive the rotary table 2 to rotate relative to the positioning chuck 4, the upper cover cannot rotate relative to the rotary table in the clockwise direction, and the upper cover can rotate relative to the rotary table in the counterclockwise direction. The spring 3 is arranged between the upper cover 1 and the positioning chuck 4 to drive the rotated upper cover 1 to reset.
In this embodiment, the distance between the two lower limit blocks 52 is only for the linkage ratchet 11 to rotate by one tooth position to generate an audible alarm sound.
A limiting strip 51 is arranged in the lower cover 5, and a limiting groove 44 matched with the limiting strip 51 is arranged on the outer side wall of the positioning chuck 4, so that the positioning chuck 4 is matched with the lower cover 5 in a circumferential limiting way.
The four resilient pawls 41 are formed on the circumferential side wall of the positioning clip 4 in a circumferentially uniform distribution.
Be equipped with first trough of belt registration arm 12 in the upper cover 1, be equipped with second trough of belt registration arm 43 in the location chuck 4, spring 3 installs in first trough of belt registration arm 12 and overlaps simultaneously on second trough of belt registration arm, and the upper end block of spring 3 is in the groove 121 of first trough of belt registration arm 12 simultaneously, and the lower extreme 31 block of spring 3 is in the inslot of second trough of belt registration arm 43.
The carousel 2 middle part is equipped with first direction 22 placed in the middle, be equipped with second direction 42 placed in the middle in the location chuck 4, first direction 22 placed in the middle cooperates with second direction 42 placed in the middle, realizes the stable rotation of carousel.
The link pawl 23 is in a horizontal state and has a wave-shaped structure, so that the structural strength of the link pawl 23 is improved.
When the upper cover 1 is screwed clockwise by hand, the linkage ratchet 11 on the inner surface of the upper cover 1 acts on the linkage pawl 23 on the rotary disc 2 to drive the rotary disc 2 to rotate clockwise synchronously, the rotary disc 2 drives the sounding ratchet 21 to slide over the elastic sounding pawl 41 on the positioning chuck 4, the elastic sounding pawl 41 jumps to impact the sounding ratchet 21 to generate a click prompt sound, after each jump of one tooth, the upper limit block 13 on the upper cover 1 abuts against the lower limit block 52 on the lower cover 5 to prevent the upper cover 1 from rotating continuously, and the click prompt sound which only jumps once is generated by each screwing is ensured.
After the upper cover 1 is released by hand, the upper cover 1 is driven by the spring 3 in a twisted state, the linkage ratchet 11 in the upper cover 1 overcomes the elastic resistance of the linkage pawl 23, slides over the head of the linkage pawl 23, the upper cover 1 returns anticlockwise, and after the linkage ratchet 11 in the upper cover 1 returns to a tooth position, the upper limit block 13 on the upper cover 1 abuts against the lower limit block 52 on the lower cover 5 to prevent the upper cover 1 from continuing to rotate, so that the upper cover 1 returns anticlockwise to the initial position of the lower cover 5.
