Oil tank anti-theft system

Abstract

The invention discloses an oil tank anti-theft system, which includes a mechanical coded lock; the mechanical coded lock includes a key fixing seat, a connecting cover, a mechanical lock core and a chuck; a button is arranged at the top of the key fixing seat; the connecting cover, the mechanical lock core and the chuck are sequentially arranged in the key fixing seat and the mechanical lock coreis arranged on the chuck; the chuck extends into the oil filling port of the oil tank; the button includes a plurality of unlocking buttons, a plurality of code destroying buttons and a locking button; sequentially pressing the unlocking button according to the unlocking password sequence to drive the mechanical lock core to step out of the lock gradually; pressing any code destroying button and the locking button can drive the mechanical lock core to lock the oil filling port of the oil tank to limit the extraction of the key fixing seat. According to oil tank anti-theft system, the structureis ingenious. The mechanical lock is not easily damaged. The mechanical coded lock adopts mechanical transmission and the safety of the fuel in the oil tank is guaranteed. The design of the unlockingbutton and the destroying button avoids code being peeped. The password can be input in a false action and the password leakage is prevented.

Description

technical field [0001] The invention relates to a fuel tank anti-theft system. Background technique [0002] Since the second industrial revolution, the extensive use of gasoline engines and diesel engines has increased the production and demand of oil. Oil has become the most important raw material in modern industrial society, and its price is also rising. Nowadays, cars and trucks have become the main means of travel and transportation for people, and many criminals obtain ill-gotten gains by stealing gasoline or diesel through oil pipes. Through market research and literature search, most of the fuel tank caps currently on the market are ordinary key locks, outer covers, atomic locks and so on. A logistics company chooses ordinary locks on the market. Many lawbreakers use violent demolition methods to steal oil. Don't come out and wait for questions. The existing anti-theft fuel tank caps on the market have a low safety factor and cannot prevent violent removal and pr...
