Description

Technical Field

[0001] The utility model relates to the technical field of anti-theft fuel tanks, in particular to an anti-theft fuel tank for a diesel vehicle. Background Art

[0002] At present, motor vehicles have become a relatively popular means of travel in today's society. The fuel tank is a container on a motor vehicle for storing fuel, usually suspended at the bottom of a large vehicle near the front wheels. The fuel tank must have a sufficiently large volume to ensure that the vehicle can travel a sufficient distance.

[0003] At present, the fuel tank caps on the market are basically locked with locks to prevent theft. Such a method is not only cumbersome for users during use, but also requires taking out the key to unlock the lock, and it cannot truly achieve the anti-theft effect. Thieves can easily pry open the lock and insert a hose into the fuel tank through the fuel tank inlet to steal the fuel in the fuel tank. Content of the Utility Model

[0004] (1) Technical Problems to be Solved

[0005] In view of the deficiencies of the prior art, the utility model provides an anti-theft fuel tank for a diesel vehicle. Its advantages are that the oil leakage groove and oil leakage hole are provided to facilitate the injection of diesel into the fuel tank body through the fuel filling pipe. The outer shell is provided to protect the outside of the fuel tank body. The baffle is provided to block the fuel filling pipe. When the baffle is intervened by external force from thieves, the baffle slides downward along the inner wall of the fuel filling pipe, so that the baffle presses down the first spring and the hinge rod. The hinge rod rotates around the hinge point and pushes the block, so that the block slides along the inner wall of the oil leakage groove and stretches the second spring, so that the block blocks the oil leakage hole, preventing thieves from inserting the oil suction pipe into the fuel tank body and improving the anti-theft performance of the fuel tank body.

[0006] (2) Technical Solutions

[0007] To achieve the above object, the utility model provides the following technical solutions: an anti-theft fuel tank for a diesel vehicle, including an outer shell. The bottom inner wall of the outer shell is fixedly connected with a fuel tank body. The top of the outer shell is provided with an oil inlet, and an oil tank cap is arranged on the oil inlet. A fuel filling pipe is fixedly connected between the oil inlet and the fuel tank body. The bottom end of the fuel filling pipe is hermetically arranged and extends into the interior of the fuel tank body. An oil leakage groove is opened on the inner wall of the fuel filling pipe, and an oil leakage hole is opened on the inner wall of the oil leakage groove. A protection mechanism is arranged in the fuel filling pipe;

[0008] The protection mechanism includes: a stop block and a first spring. The stop block is slidably connected to the inner wall of the oil leakage groove. The first spring is fixedly connected to the bottom inner wall of the fuel filling pipe. The top end of the first spring is fixedly connected to a baffle, and the outer wall of the baffle is slidably connected to the inner wall of the fuel filling pipe. The bottom of the baffle is hinged with a hinge rod, and the bottom end of the hinge rod is hinged to the top of the stop block. Through the provided oil leakage groove and oil leakage holes, diesel can be conveniently injected into the fuel tank body through the fuel filling pipe. Through the provided outer shell, the outside of the fuel tank body can be protected. Through the provided baffle, the fuel filling pipe can be blocked. And when an external force is applied by a thief to the baffle, the baffle slides downward along the inner wall of the fuel filling pipe, so that the baffle presses down the first spring and the hinge rod. The hinge rod rotates around the hinge point and pushes the stop block, so that the stop block slides along the inner wall of the oil leakage groove and stretches the second spring, so that the stop block blocks the oil leakage hole, preventing the thief from inserting the oil suction pipe into the fuel tank body and improving the anti-theft performance of the fuel tank body.

[0009] Preferably, the oil leakage groove is arranged in an "L" shape, and the oil leakage hole is opened at the bottom inner wall of the oil leakage groove.

[0010] Preferably, a sliding groove is opened on the inner wall of the oil leakage groove, and both the front and rear sides of the stop block are slidably connected to the sliding groove.

[0011] Preferably, a second spring is fixedly connected to the right side of the stop block, and the other end of the second spring is fixedly connected to the inner wall of the oil leakage groove. When the stop block moves under force, the second spring can be stretched. On the contrary, under the action of its own elastic force, the second spring can drive the stop block to reset, thus opening the oil leakage hole.

[0012] Preferably, the number of the oil leakage grooves, oil leakage holes, stop blocks, hinge rods and second springs is four groups, and they are arranged in an equidistant circle.

[0013] Preferably, a filtering mechanism is arranged in the fuel filling pipe. The filtering mechanism includes: a mounting ring, which is fixedly connected to the inner wall of the fuel filling pipe. A fixing ring is fixedly installed on the top of the mounting ring, and a net bag is fixedly connected to the inner wall of the fixing ring. Through the provided net bag, sundries can be prevented from entering the fuel tank body, and it can also prevent the thief from inserting the oil suction pipe into the fuel filling pipe, further improving the anti-theft performance of the fuel tank body.

[0014] (III) Beneficial effects

[0015] Compared with the prior art, the present utility model provides an anti-theft fuel tank for a diesel vehicle, which has the following beneficial effects:

[0016] 1. The anti-theft fuel tank for a diesel vehicle facilitates the injection of diesel into the fuel tank body through the provided oil leakage groove and oil leakage holes. The outer shell can protect the outside of the fuel tank body, and the baffle can block the fuel filling pipe. When the baffle is intervened by external force from thieves, the baffle slides down along the inner wall of the fuel filling pipe, thus pressing down the first spring and the hinge rod. The hinge rod rotates around the hinge point and pushes the stopper, so that the stopper slides along the inner wall of the oil leakage groove and stretches the second spring, thereby blocking the oil leakage hole with the stopper, preventing thieves from inserting the oil suction pipe into the fuel tank body and improving the anti-theft performance of the fuel tank body.

[0017] 2. The anti-theft fuel tank for a diesel vehicle can prevent sundries from entering the fuel tank body through the provided net pocket and also prevent thieves from inserting the oil suction pipe into the fuel filling pipe, further improving the anti-theft performance of the fuel tank body.
