Technical field
The present invention relates to a kind of oil-stolen preventing device for oil tank of vehicle, particularly a kind of device for preventing oil-stealing that oil-draining locknut at the bottom of oil tank of vehicle is transformed.
Technical background
Recent years, along with the fierce growth of China's automobile consumption demand and the factor such as whole world crude oil is in short supply and International Crude Oil rises steadily, internal vapor, diesel-fuel price rapidly go up.The fuel oil larceny case of particularly large-scale transport, working truck occurs repeatedly, and criminal is therefrom sought exorbitant profit, and What is more, and some of them unprincipled fellow takes advantage of one's position and embezzles public funds, and acquires wealth unjustly greatly.It is short that it has crime time, and the crime cycle is not fixed, and the feature such as not easily to be arrested, make the related personnel such as car owner, driver suffer huge economic loss.
Analyze its modus operandi, most oil plant larceny case is mainly committed a crime by following aspect: 1, destroy oil circuit, transformation oil circuit.2, destroy fuel lid, use high speed oil pumper to steal.3, tank body of oil tank is destroyed.4, the oil-draining locknut crime of tank bottoms is turned on.
There are some anti-joyride devices for front 3 kinds of ways of committing offenses or system in the market.But the 4th kind is often ignored by people.Take this way of committing offenses of oil-draining locknut of turning on oil tank bottom to be characterized in: need not use speciality tool, simple, quick, crime time is short, is not easily therefore easily perceived by humans.And the existing anti-joyride device for the 4th kind of crime is also only install bright lock outward at oil-draining locknut, and structure is simple, and anti-theft effect is poor.
Summary of the invention
Goal of the invention of the present invention is the oil-draining locknut modus operandi for turning on tank bottoms, provides that a kind of structure is simple, reliable effect, guard against theft oil are effective and need not carry out the device for preventing oil-stealing acting on oil-draining locknut at the bottom of oil tank of vehicle of large transformation to former oil-draining locknut.
Technical scheme of the present invention is a kind of device for preventing oil-stealing acting on oil-draining locknut at the bottom of oil tank of vehicle, comprises magnet coil, reaction plate, lock collar, hitching post, stop bar and spring, it is characterized in that,
The center of described reaction plate has the female through hole of band, uniform at least 2 blind holes on the lower surface of reaction plate,
Described lock collar upper surface fixed installation hitching post, the axis of hitching post is vertical with lock collar upper surface, and lock collar lower surface is installed with the stop bar vertical with lock collar lower surface, and lock collar center has the through hole of diameter slightly larger than oil-draining locknut screw diameter,
" C " connected in star that the screw terminal of described oil-draining locknut has towards the surface of screw thread side,
Described reaction plate to utilize the coaming plate of its circumference to be fixed on to be arranged on the oil tank of vehicle plate inner surface at oil-draining locknut place and leaves gap with oil tank of vehicle plate inner surface, oil-draining locknut is tightened through the screw-internal thread fit on the through hole at lock collar center and the through hole at reaction plate center, hitching post inserts in magnet coil through the through hole that corresponding position on reaction plate has, lock collar upper surface has the blind hole of equal number with the blind hole corresponding position on reaction plate, one end of described spring is installed in the blind hole on the lower surface of reaction plate, the other end of spring is arranged in the blind hole on lock collar upper surface,
When magnet coil is not energized, lock collar is pressed on oil tank of vehicle plate inner surface by spring, and stop bar inserts in " C " connected in star on oil-draining locknut through the through hole that corresponding position on oil tank of vehicle base plate has,
When magnet coil is energized, hitching post is upwards mentioned, and stop bar departs from " C " connected in star on oil-draining locknut.
Further, the coaming plate full weld of described reaction plate circumference on oil tank of vehicle plate inner surface, hitching post and its through reaction plate on there is slipper seal the through hole that has of corresponding position.
The invention has the beneficial effects as follows the device for preventing oil-stealing acting on oil-draining locknut at the bottom of oil tank of vehicle of the present invention, only adopt several simple components and install simple and reliable, adopt universal electromagnetic coil reliable effect, when stop bar is stuck on oil-draining locknut, oil-draining locknut cannot be backed out, guard against theft oil is effective, and need not carry out large transformation to the structure of former oil-draining locknut, has very large economic benefit.

Detailed description of the invention:
Below in conjunction with embodiment and accompanying drawing, further detailed description is done to the present invention, but embodiments of the present invention are not limited thereto.
As shown in Figure 1-2, a kind of device for preventing oil-stealing acting on oil-draining locknut at the bottom of oil tank of vehicle of the present invention, comprises magnet coil 1, reaction plate 2, lock collar 3, hitching post 4, stop bar 5 and spring 6.
The center of described reaction plate 2 has the female through hole of band, uniform at least 2 blind holes on the lower surface of reaction plate 2.
