Abstract

The utility model discloses a novel spiral type autorotation anti-theft oil tank cover which comprises an oil tank cover outer ring. An inner fixed shell capable of rotating relatively is arranged in the oil tank cover outer ring. Outer threads are arranged below the inner fixed shell. An outer thread oiling filler is sleeved with a first sealing ring and is connected with a sealing ring pressure plate with inner threads. An oil tank opening fixing paw is placed in an oil tank opening. The oil tank opening fixing paw and the sealing ring pressure plate are fixed on the oil tank opening through oil tank opening threads. A second sealing ring is arranged between the oil tank opening fixing paw and the sealing ring press plate. The novel spiral type autorotation anti-theft oil tank cover has the advantages that sealing is adjusted through vertical movement of outer threads and inner threads of the sealing cover pressure plate, the height is adjusted through the oil tank opening pressure plate with inner threads and the oil tank opening fixing paw, and autorotation of the outer cover and autorotation of the inner fixing shell are realized through controlling a spring bolt to leave the outer threads.

Description

Novel screw type rotation Thfet-proof cover of fuel tank

Technical field

The utility model relates to a kind of Thfet-proof cover of fuel tank, relates to a kind of energy and is suitable for the Thfet-proof cover of fuel tank that the spiral of different reservoir ports and sealing rear fuel tank lid outer ring can rotations.

Background technique

I have applied for a Thfet-proof cover of fuel tank before, am also the Thfet-proof cover of fuel tank with enclosing cover rotation, and having a defect is exactly that reservoir port height differs, and what cause like this that reservoir port that a lot of specifications are different installs is not ideal.

Model utility content

For the deficiencies in the prior art, the spiral enclosing cover rotation Thfet-proof cover of fuel tank that the utility model provides a kind of energy regulating oil tank mouth height to differ.

To achieve these goals, technical solution adopted in the utility model is:

Novel screw type rotation Thfet-proof cover of fuel tank, comprise fuel tank cap outer ring, in fuel tank cap outer ring, be provided with and can be in relative rotation in fixing shell, interior fixing shell below is provided with outside thread oil filler, outside thread oil filler overcoat has the first seal ring, outside thread oil filler is connected with tapped seal ring pressing plate, the fixing claw of reservoir port is placed in reservoir port, by reservoir port screw, fixing reservoir port claw and seal ring pressing plate are fixed on reservoir port, and are provided with the second seal ring between the fixing claw of reservoir port and seal ring pressing plate; In be equipped with through hole in the middle of fixing shell, outside thread, spring top cover, and middle main shaft from upper end successively through through hole, bottom is through spring and spring top cover and nut, and middle main the tip of the axis is by cotter pin pinning; Between the fixing claw of the reservoir port pressing plate of internal thread and reservoir port, have through hole, and screw is from the fixing claw of reservoir port seal ring pressing plate upper end connection reservoir port, realizes reservoir port height and regulates; In fuel tank cap outer ring, there is fixing shell, there is through hole at the center of interior fixing shell, in through hole, be provided with lock core base, in lock core base, be provided with lock core, in lock core base, cross out two dead bolts, and on dead bolt, cover has latch bolt spring, by fuel tank cap key, insert in lock core, control dead bolt and stretch out or retract in the interior breach of fixing shell, fixing shell in pilferproof closure outer ring rotating drives, make relative the moving up and down of internal thread spiral of externally threaded screw thread and sealing cover pressing plate, realize sealing.

The lock core port of pilferproof closure outer ring is provided with capable of opening and closing dust cover.

The beneficial effects of the utility model: the adjusting moving up and down by the internal thread of outside thread and sealing cover pressing plate realizes sealing, regulate height with the reservoir port pressing plate of internal thread and the fixing claw of reservoir port, use to control after dead bolt leaves outside thread and realize enclosing cover and interior fixing shell rotation.

Embodiment

As depicted in figs. 1 and 2, novel screw type rotation Thfet-proof cover of fuel tank, comprise fuel tank cap outer ring 1, in fuel tank cap outer ring 1, be provided with and can be in relative rotation in fixing shell 2, interior fixing shell 2 belows are provided with outside thread 12, outside thread 12 thread jackets have the first seal ring 13, outside thread 12 outside threads are connected with tapped seal ring pressing plate 3, the fixing claw 4 of reservoir port is placed in reservoir port, use reservoir port screw 14 that fixing reservoir port claw and seal ring pressing plate 3 are fixed on reservoir port, and be provided with the second seal ring 15 between the fixing claw 4 of reservoir port and seal ring pressing plate 3; In be equipped with through hole in the middle of fixing shell 2, outside thread 12, spring top cover 17, and middle main shaft 11 from upper end successively through through hole, bottom is through spring 16 and spring top cover 17 and nut 18, and the end of middle main shaft 11 is by cotter pin 19 pinnings; Between the fixing claw 4 of the reservoir port pressing plate 3 of internal thread and reservoir port, have through hole, and screw 14 is from the fixing claw 4 of reservoir port seal ring pressing plate 3 upper ends connection reservoir port, realizes reservoir port height and regulates; In fuel tank cap outer ring 1, there is fixing shell 2, there is through hole at the center of interior fixing shell 2, in through hole, be provided with lock core base 8, in lock core base 8, be provided with lock core 7, in lock core base 8, cross out two dead bolts 10, and on dead bolt 10, cover has latch bolt spring 9, by fuel tank cap key 6, insert in lock core 7, controlling dead bolt 10 stretches out or retracts in the interior breach of fixing shell 2, pilferproof closure outer ring 1 is fixing shell 2 in rotating and driving, make relative the moving up and down of internal thread spiral of outside thread with the sealing cover pressing plate 3 of outside thread 12, realize sealing.When dead bolt 10 leaves outside thread 12, between fuel tank cap outer ring 1 and interior fixing shell 2, relatively rotate but depart from outside thread 12, even if thief has destroyed fuel tank cap outer ring 1 and fixing shell 2, also outside thread 12 and seal ring pressing plate 3 can not destroyed.

The lock core port of pilferproof closure outer ring 1 is provided with the dust cover 5 of energy left-right rotation, covers and can block dust, while unblanking, can left-right rotation open.

Can rotation after antitheft enclosing cover and interior fixing shell lock; Fixing claw energy regulating oil tank mouth height; Spiral design good seal performance.
