Motor vehicle fuel burglarproof sleeve

Abstract

The invention relates to a motor vehicle fuel burglarproof sleeve for preventing absorbing and stealing fuel from a fuel injection port of a motor vehicle fuel tank. The sleeve is made of a cylindrical steel pipe with slightly smaller diameter than the fuel injection port of the motor vehicle fuel tank, the space in the pipe is divided into a larger cylinder and a smaller cylinder through a rectangle steelplate, the bottom of the larger cylinder is sealed by the steelplate, sponge with the height of 30 cm is matted at the bottom, a fuel-spill aperture is arranged at a nozzle part, and the fuelis decompressed through the sponge, then reflows to the nozzle from the bottom and flows into the fuel tank through the fuel-spill aperture when the fuel is filled. The bottoms of the smaller spaces are communicated with the fuel tank, a buoy scale is placed inside, and the fuel can be filled into the fuel tank according to the graduation shown on the scale when the fuel is filled. A burglarproof sleeve is welded in the fuel injection port of the motor vehicle fuel tank and then becomes the motor vehicle fuel burglarproof sleeve. The structures of the fuel tank and a fuel tank cover of the sleeve do not need to be changed so as to achieve the purpose of preventing absorbing and stealing the fuel from the fuel injection port; and under the condition of fuel gauge failure of a motor vehicle, the motor vehicle fuel burglarproof sleeve can also perform a function of indicating the fuel storage capacity of the fuel tank.

Description

Technical field: [0001] The invention is a device which is welded in the oil filling port of the fuel tank of the motor vehicle and prevents the fuel from being sucked by the tubular object. Background technique: [0002] Motor vehicle is an indispensable tool in people's production and life. Due to the weak anti-theft measures and poor anti-theft performance of the fuel tank of motor vehicles, the oil filling port of the fuel tank is only locked with ordinary locks. Suck theft. Invention content: [0003] In order to overcome the problem that the oil in the fuel tank of the motor vehicle is easily stolen by the tubular object, the invention provides a fuel anti-theft sleeve for the motor vehicle; the anti-theft sleeve solves the problem of stealing fuel through the oil filling port of the fuel tank with the oil suction pipe; The automatic buoy gauge in the anti-theft sleeve also indicates the fuel level in the fuel tank in the event of a motor vehicle fuel failure.
