Problems solved by technology

In various reports, it is often seen that thieves steal fuel from large trucks when they are parked overnight. The next day, they find that the fuel tank has been emptied, which not only causes economic losses to the owners, but also affects normal work.
[0003] Existing anti-theft methods generally improve the fuel tank itself, that is, add corresponding anti-theft functions to fuel tanks that have not been filled with fuel or newly produced fuel tanks, which causes some car owners who still use old-fashioned fuel tanks without anti-theft functions. Had to replace the fuel tank, causing unnecessary economic losses

Abstract

The invention relates to an anti-theft oil tank which comprises an anti-theft filter drum, wherein a plurality of oil passing holes are formed in the bottom wall or the side wall at the lower end of the anti-theft filter drum; a first ring flange connected with an oil tank cap is arranged at the top of the anti-theft filter drum; a second ring flange fixed with an oil tank port is arranged below the first ring flange; the anti-theft filter drum is inserted in the oil tank; and the second ring flange and the oil tank port are fixed by a ring lock hoop and are locked by permanent locking pieces. The anti-theft oil tank has the beneficial effects that the anti-theft oil tank has a simple structure and is low in cost; and oil stealers can be prevented from inserting oil stealing suckers in the oil liquid and the oil liquid can be prevented from being stolen only by installing an anti-theft filter screen on the basis of an original oil tank, without changing the original oil tank.

Description

technical field [0001] The invention relates to a fuel tank, in particular to an anti-theft fuel tank. Background technique [0002] At present, the fuel tanks of large vehicles or large equipment are provided with filling ports, and the filling ports have a lid that can be tightened. During normal operation, the fuel tank can be refueled by unscrewing the fuel tank cap. Oil can also be sucked out from the tank at the same time. In various reports, it is often seen that when a large freight vehicle is parked overnight, thieves steal fuel, and the fuel tank is found to be empty the next day, which not only causes economic losses to the owner, but also affects normal work. [0003] Existing anti-theft methods generally improve the fuel tank itself, that is, add corresponding anti-theft functions to fuel tanks that have not been filled with fuel or newly produced fuel tanks, which causes some car owners who still use old-fashioned fuel tanks without anti-theft functions.
