Problems solved by technology
[0002] At present, the existing automobile fuel tank lock is provided with an internal thread on the inner side of the cover edge of the lock cylinder, which has the problem of poor sealing performance during use, and there is a phenomenon of oil leakage when the automobile is running bumpy.
As the Chinese patent was authorized and announced on June 4, 2014, the authorized announcement number is a kind of anti-theft and anti-leakage fuel tank cap CN203623373U, which is simple in structure, easy to use, safe and firm, low in cost, stable in performance, and relatively tight. Well, it can effectively avoid the phenomenon of oil leakage and waste of oil during the bumpy driving of the car. It also discloses that there are three buckles on the fixing plate and the positioning buckles on the positioning plate at the bottom of the outer cover can make the connection between the outer cover and the fuel tank neck easier. Strong, but the anti-theft effect is relatively poor, giving criminals a chance to pry open the top cover to steal automobile oil

The invention discloses a 360° rotatable anti-theft fuel tank lock. The lock cylinder installation cylinder is inserted from the lock cylinder installation hole on the front of the upper cover and can be 360° rotatably installed on the upper cover. The lock cylinder is inserted into the lock cylinder through the first sealing pad. In the installation cylinder, an oil-proof baffle is installed at the bottom of the lock cylinder, and the lock cylinder and the oil-proof baffle are connected by a spring. On the cover, the second sealing gasket and the second positioning plate are placed in sequence on the first positioning plate. The oil leakage surface of the lock cylinder installation cylinder, the first positioning plate and the second positioning plate are all provided with corresponding installation holes. The mounting holes on the mounting cylinder, the first positioning plate and the second positioning plate are fixed on the fuel tank port through the connecting piece. The invention has the advantages of simple structure, convenient use, safety and firmness, low manufacturing cost and stable performance, effectively avoids oil seepage and waste of oil during bumpy driving, and has good sealing effect and anti-theft effect.
