Embodiment Construction
[0018] The present invention will be further described in detail below in conjunction with the embodiments and the accompanying drawings, but the embodiments of the present invention are not limited thereto.
[0019] Such as Figure 1-2 As shown, a kind of anti-theft oil device of the present invention acting on the oil discharge screw at the bottom of the vehicle fuel tank includes an electromagnetic coil 1, a fixed disc 2, a lock disc 3, a bolt post 4, a stop bar 5 and a spring 6.
[0020] The center of the fixed disk 2 is provided with a through hole with an internal thread, and at least two blind holes are evenly distributed on the lower surface of the fixed disk 2 .
[0021] The upper surface of the lock disc 3 is fixedly installed with a bolt column 4, the axis of the bolt column 4 is perpendicular to the upper surface of the lock disc 3, and the lower surface of the lock disc 3 is fixedly installed with a stop rod 5 perpendicular to the lower surface of the lock disc 3,...

The invention relates to an oil drainage screw device for preventing vehicle fuel oil from being stolen. The oil drainage screw device comprises an electromagnetic coil (1), a fixing disc (2), a locking disc (3), a bolting column (4), a stop rod (5) and a spring (6), and is characterized in that when the electromagnetic coil (1) is not powered on, the locking disc (3) is pressed on the inner surface of a bottom plate of a vehicle oil tank by the spring (6), and the stop rod (5) penetrates through a through hole formed in a corresponding position of the bottom plate of the vehicle oil tank to be inserted into a C-shaped groove in an oil drainage screw; when the electromagnetic coil (1) is powered on, the bolting column (4) is lifted up, and the stop rod (5) is separated from the C-shaped groove in the oil drainage screw. According to the oil drainage screw device acting on the oil drainage screw at the bottom of the vehicle oil tank, only several simple components are adopted, so that installation is easy and reliable; effect is reliable due to the adoption of the universal electromagnetic coil, the oil drainage screw cannot be screwed off when clamped by the stop rod, and the oil theft preventing effect is good; besides, the structure of the existing oil drainage screw does not need to be modified greatly, and therefore great economic benefits can be achieved.
Description
technical field [0001] The invention relates to an anti-theft oil device for a vehicle fuel tank, in particular to an anti-theft oil device for modifying the oil discharge screw at the bottom of the vehicle fuel tank. technical background [0002] In recent years, with the rapid growth of my country's automobile consumption demand, the shortage of crude oil in the world and the continuous rise of international crude oil prices, domestic gasoline and diesel prices have risen rapidly. In particular, fuel theft cases of large-scale transportation and operating vehicles have occurred frequently, and criminals have made huge profits from them. What's more, some criminals have used their positions to fill their own pockets and make a lot of ill-gotten wealth. It has the characteristics of short committing time, irregular committing cycle, and not easy to be caught, which causes huge economic losses to car owners, drivers and other related personnel. [0003] Analyzing its modus o...
