Problems solved by technology
[0002] I applied for an anti-theft fuel tank cap before, which is also an anti-theft fuel tank cap with an outer cover that rotates. One defect is that the height of the fuel tank port is different, which leads to the unsatisfactory installation of many fuel tank ports with different specifications.

The invention discloses a novel spiral self-rotation anti-theft oil tank cover, which comprises an oil tank cover outer ring, wherein an inner fixed shell capable of rotating relatively is arranged in the oil tank cover outer ring; external threads are formed below the inner fixed shell; a first sealing ring is sleeved outside an external thread oil filling port; the external thread oil filling port is connected with a sealing ring pressure plate which is provided with internal threads; an oil tank port fixing claw is placed into an oil tank port; the oil tank port fixing claw and the sealing ring pressure plate are fixed on the oil tank port through oil tank port screws; a second sealing ring is arranged between the oil tank port fixing claw and the sealing ring pressure plate. The novel spiral self-rotation anti-theft oil tank cover has the beneficial effects that sealing is realized by adjusting in a way of moving the external threads and the internal threads of the sealing cover pressure plate up and down, the height is adjusted by using an oil tank port pressure plate with internal threads and the oil tank port fixing claw, and a control spring bolt is separated from the external threads, so that self-rotation of an outer cover and the inner fixed shell is realized.
Description
technical field [0001] The invention relates to an anti-theft fuel tank cap, in particular to a screw-type anti-theft fuel tank cap applicable to different fuel tank ports, and the outer ring of the sealed fuel tank cap can rotate by itself. Background technique [0002] I applied for an anti-theft fuel tank cap before, which is also an anti-theft fuel tank cap with an outer cover that rotates on its own. One defect is that the height of the fuel tank port is different, which leads to unsatisfactory installation of many fuel tank ports with different specifications. Contents of the invention [0003] Aiming at the deficiencies of the prior art, the present invention provides a screw-type outer cover that can adjust the height of the fuel tank opening to prevent theft from theft. [0004] In order to achieve the above object, the technical scheme that the present invention takes is: [0005] The new spiral self-rotating anti-theft fuel tank cap includes the outer ring of t...
