Abstract
The invention discloses a novel self-rotation anti-theft oil tank cover which comprises an anti-theft oil tank cover outer ring. An inner fixing shell is arranged in the anti-theft oil tank cover outer ring, the outer side edge of the inner fixing shell is connected with the inner side edge of the anti-theft oil tank cover outer ring in a close-fit mode, a lock cylinder is arranged between the anti-theft oil tank cover outer ring and the inner fixing shell, a key opening in the upper portion of the key cylinder aligns at a central hole in the anti-theft oil tank cover outer ring, the lock cylinder is arranged in a lock cylinder base, and the lock cylinder is in transmission connection with a spring bolt. The novel self-rotation anti-theft oil tank cover has the advantages that after an oil tank cover is locked, the anti-theft outer ring can conduct self rotation, and role in preventing the oil tank cover from being stolen and pried is played.
Description
Technical field
The present invention relates to a kind of fuel tank cap, particularly a kind of Thfet-proof cover of fuel tank.

Summary of the invention
For the deficiencies in the prior art, the invention provides a kind of Novel autorotation Thfet-proof cover of fuel tank.
To achieve these goals, the technical solution used in the present invention is:
The Novel autorotation Thfet-proof cover of fuel tank, comprise the Thfet-proof cover of fuel tank outer ring, be provided with interior set casing in the Thfet-proof cover of fuel tank outer ring, and the outer edge of interior set casing is connected with the inside edge close-fitting of Thfet-proof cover of fuel tank outer ring, be provided with lock core between Thfet-proof cover of fuel tank outer ring and interior set casing, the top key mouth of lock core is aimed at the center hole of Thfet-proof cover of fuel tank outer ring, lock core is positioned at lock core base, lock core is connected with dead bolt, and be connected with two latch bolt springs between dead bolt and lock core base, two latch bolt springs lay respectively at the both sides of dead bolt, be provided with through hole in the middle of interior set casing, bolt axis is passed down through from the top of interior set casing, be installed with the seal ring supporting plate under bolt axis, be fixedly connected with bolt-fixing board in the upper surface of seal ring supporting plate, bolt-fixing board is that sidewall is established basin shape jaggy, the lower surface outer ring of seal ring supporting plate is provided with seal ring, the lower surface of seal ring supporting plate is provided with at least two locating columns, on locating column, cover has claw iron plate, the periphery of claw iron plate is provided with at least two claws corresponding with the breach of tank filler, the below of claw iron plate, the upper cover of bolt axis has spring, there is spring top cover on top, spring below, and the centre of spring top cover is provided with through hole, and bolt axis is through middle through hole, finally pass through nut, split washer is fixed, open lock core, dead bolt reaches in the breach of bolt-fixing board, and band dynamic seal ring supporting plate, rotate together, thereby make the rotation of claw iron plate, the claw of claw iron plate turns to the locked position of tank filler, and while closing lock core, dead bolt is retracted from the indentation, there of bolt-fixing board, thereby, rotate together with interior set casing the Thfet-proof cover of fuel tank outer ring, breaks away from the motion of seal ring supporting plate, forms rotation.
The Thfet-proof cover of fuel tank outer ring is connected with dust cover by pivot pin.
Interior set casing lower surface is provided with some projections.
Beneficial effect of the present invention: the antitheft outer ring of this fuel tank cap can rotation after pinning.Interior fixedly shell is fixed in outer pilfer band.Main shaft is fixedly arranged in the middle of shell, lock, lock core, dead bolt fixedly are installed in shell.On lock, there are two springs to catch on dead bolt, control the dead bolt effect.Below shell, be fixedly circle supporting plate sealing together and two stationary axle bolt-fixing boards, built-in seal ring is tamping oil filler, claw iron plate is arranged below supporting plate, and claw catches on tank filler.Install the claw back, spring, spring cover, nut, split washer.This fuel tank cap is pinned rear defence and is stolen outer ring meeting rotation, plays the anti-theft pick-proof effect.
