Abstract
The present invention relates to a burglarproof device and especially a burglarproof cover device of an oil box. The device is provided with a burglarproof cylinder, the bottom of which is provided with a plurality of close distributed oil inlet holes. The lateral side of the burglarproof cylinder is also provided with a plurality of accessory oil inlet holes. An upper layer of the oil inlet holes at the bottom of the burglarproof cylinder is also provided with a burglarproof net. A fixing ring is arranged at an opening above the burglarproof cylinder. The fixing ring is fixedly connected with the oil box, and screw threads of the fixing ring are screwed with the burglarproof cover, which is embedded inside a concave cavity. The burglarproof cover is provided with a lock and a manually screwing convex block. The beneficial effects of the present invention are the simple structure and effective prevention of the occurrence of the accident that the fuel in the oil box is stolen.
Description
Technical field
The present invention relates to a kind of anti-joyride device, especially a kind of oil box theft-proof cap device.
Background technology
Present truck, general no anti-joyride device on its fuel tank, or just on fuel tank flap, establish a common lock, its anti-theft effect is relatively poor, therefore, parks when truck, after the driver leaves, the stolen accident of fuel oil in the fuel tank takes place easily.The oil stealer carries out stolen by oil pipe with the outside sucking-off of the fuel oil in the case.Establish a common lock on the fuel tank flap, though can play certain antitheft effect, it is easy to by general tamper tool, so its anti-theft effect is still not good.
Summary of the invention
In order to overcome the deficiencies in the prior art, reduce the generation of oil tank fuel robbery accident conscientiously, the invention provides a kind of oil box theft-proof cap device.
The technical solution adopted for the present invention to solve the technical problems is: a kind of oil box theft-proof cap device, has antitheft tube, offer the fuel feed hole of a plurality of tight distribution in the bottom of antitheft tube, opening part above antitheft tube is provided with mounting ring, mounting ring is captiveed joint with fuel tank, and screw thread is installed with pilfer proof closure on mounting ring.By fuel feed hole is set, fuel oil can inject fuel tank through fuel feed hole when on the one hand guaranteeing to refuel, and on the other hand, having prevented that the oil stealer from can directly stretch into oil pipe in the fuel oil in the fuel tank carries out stolen, played good insulating effect, thereby prevented that fuel oil is stolen by suction pipe in the case.
In order to stop the oil pipe that the oil stealer adopts littler caliber, oil pipe is passed the possibility that fuel feed hole stretches into fuel tank, further: the bottom of described antitheft tube also is lined with anti-theft net.
When consideration is refueled to fuel tank, when the flow that enters antitheft tube when fuel oil enters the flow of fuel tank greater than fuel oil by fuel feed hole, fuel oil can outwards overflow from antitheft nozzle, thereby cause fuel loss, potential safety hazard occurs, further: the side of described antitheft tube also offers a plurality of auxiliary fuel feed holes, when the fuel oil in the antitheft tube can not in time enter in the fuel tank by end filler port, can expand the oil-feed path by auxiliary fuel feed hole oil-feed.
In order better to reach anti-theft effect, farthest reduce the oil stealer oil pipe is stretched into antitheft possibility, further: mounting ring is provided with cavity, and pilfer proof closure buries and is contained in the cavity, and pilfer proof closure is provided with lock in addition.When pilfer proof closure after tightening on the mounting ring, key is inserted lockhole, key is stretched out dead bolt, blocks mounting ring, the pilfer proof closure spin-up that just can not make progress is again opened, because the existence of cavity has prevented by utilizing instrument to pry open the possibility of pilfer proof closure by force.
For the sealing property after improving pilfer proof closure and covering, further: in the cavity of mounting ring, offer draw-in groove, be provided with seal ring in the draw-in groove, when pilfer proof closure after tightening on the mounting ring, the bottom surface and the seal ring of pilfer proof closure fit tightly, and make isolation in the fuel tank well.
Open or tighten pilfer proof closure for convenience, further: hand is set twists projection on pilfer proof closure.
The invention has the beneficial effects as follows: simple in structure, prevented the generation of the fuel oil robbery accident of fuel tank effectively.

The specific embodiment
A kind of oil box theft-proof cap device as shown in Figure 1 has antitheft tube 1, offers the fuel feed hole 2 of a plurality of tight distribution in the bottom of antitheft tube 1, and the side of antitheft tube 1 also offers a plurality of auxiliary fuel feed holes 6, and these holes can be regularly arranged, with the aesthetic property of intensifier.The perforate gross area of fuel feed hole 2 is the bigger the better in theory, and to increase the speed of passing through of fuel oil, the upper strata of the fuel feed hole 2 of antitheft tube 1 bottom also is lined with anti-theft net 5.Opening part above antitheft tube 1 is provided with mounting ring 3, mounting ring 3 is captiveed joint with fuel tank 12, be screwed into from mounting ring 3 sides as available flat head screw, the end sections of flat head screw is stretched in the oral area outer wall of fuel tank 12, simultaneously, guarantee the joint face excellent sealing performance between mounting ring 3 and the fuel tank 12, screw thread is installed with pilfer proof closure 4 on mounting ring 3, pilfer proof closure 4 is provided with lock 8 and hand is twisted projection 9, the plane is provided with lockhole on pilfer proof closure 4, and bottom surface is provided with dead bolt, and hand is twisted projection 9 can be just many positive polygon prisms for structure, be convenient on the one hand hand and twist, instrument such as metal plate hand also easy to use is screwed on the other hand.Mounting ring 3 is provided with cavity 7, and after pilfer proof closure 4 and mounting ring 3 were tightened, pilfer proof closure 4 buried and is contained in the cavity 7, offers draw-in groove 10 in cavity 7, is provided with seal ring 11 in the draw-in groove 10, and seal ring 11 can be selected oil resistant O type circle for use.Whole oil box theft-proof cap device adopts the hydrogen alumina based material to make, and is in light weight, and firm, can not get rusty.
During oiling, key is inserted the lockhole of lock 8, screw key, dead bolt rotates thereupon, and dead bolt is retracted into pilfer proof closure 4 bottom surfaces from the state that stretches out pilfer proof closure 4 bottom surfaces and fasten mounting ring 3 inner ring lower edges, and this moment, pilfer proof closure 4 just can be turned on.After backing out pilfer proof closure 4, just can in fuel tank 12, refuel from the opening of mounting ring 3, fuel oil enters in the fuel tank 12 by fuel feed hole 2 and auxiliary fuel feed hole 6.After oiling finishes, the pilfer proof closure 4 of screwing on again, screw key snaps onto mounting ring 3 inner ring lower edges again with dead bolt and locks, and pilfer proof closure 4 can not be back-outed again.
