An anti-theft device for oil tank cap of engineering machinery

Abstract

The invention relates to the technical field of anti-theft oil tank caps, and discloses an anti-theft device for oil tank caps of construction machinery, which includes an oil inlet pipe, an upper cover is arranged above the oil inlet pipe, and a first protective net is arranged under the oil inlet pipe , and the lower part of the oil inlet pipeline is located inside the first protective net and is provided with a second protective net, and the upper surface of the upper cover is located on the inner side of the fixed ring and is provided with a lock cylinder. The present invention is provided with a lock core, and through the engaging connection between the locking block on the lock core and the connecting groove, the upper cover and the oil inlet pipeline can be firmly engaged together to prevent the oil tank from being stolen. Filter the fuel tank to prevent large particles from entering the fuel tank accidentally. At the same time, through the staggered arrangement of circular through holes and diamond-shaped through holes on the two-layer protective net, it can prevent fuel thieves from extending the fuel pipe into the fuel tank, thereby further improving the fuel tank. The anti-theft function of the cover.

Description

technical field [0001] The invention relates to the field of oil tank cap anti-theft technology, in particular to an anti-theft device for an engineering machinery oil tank cap. Background technique [0002] Anti-theft fuel tank refers to a new type of fuel tank that completely solves the problem of fuel theft when the fuel tank cap is damaged, and the oil suction pipe cannot enter the fuel tank, and the fuel filler port cannot be damaged with hard objects, and the oil in the fuel tank is extracted. Composed of tank body, fuel filler, fuel tank cap and additional oil pipe, it is generally widely used in the field of industrial automobiles, and the effect of anti-stealing oil can be achieved by adding an anti-theft device to the fuel tank cap. [0003] However, the general structure of the anti-theft device for the fuel tank cap on the market is relatively simple, and it cannot achieve a complete anti-theft effect. There is no lock cylinder, and it is impossible to actively c...

AI Technical Summary

Problems solved by technology

[0003] However, the general structure of the anti-theft device for the fuel tank cap on the market is relatively simple, and it cannot achieve a complete anti-theft effect. There is no lock cylinder, and it is impossible to actively control the closure of the fuel tank cap by engaging the block on the lock cylinder with the connecting groove. function, which reduces the anti-theft effect. Without double-layer protective nets, the anti-theft effect cannot be further improved, and the oil pipes of oil thieves cannot be isolated through the staggered circular through holes and diamond-shaped through holes arranged on the protective net, which may easily lead to thieves. The oiler steals the oil tank through the oil pipe. Therefore, those skilled in the art provide an anti-theft device for the oil tank cap of construction machinery to solve the problems raised in the above-mentioned background technology
