Description

Technical Field

[0001] The invention relates to the technical field of automobile parts, in particular to an anti-theft oil tank for a truck. Background Art

[0002] As oil prices continue to soar, some criminals are willing to take risks to steal oil from car users. Since trucks often need to travel long distances and carry a large load, a larger fuel tank is needed to ensure normal transportation of the truck. Since the fuel tank is too large, it is often placed outside the vehicle body, which leads to criminals targeting the fuel tank of the truck. The value of the oil in a truck tank is often as high as thousands of yuan, which causes the driver to be nervous when sleeping at night or sleep directly next to the fuel tank. At present, the market often adds a lock structure to prevent criminals from stealing oil, but once the lock is pried open, the criminals can still steal the oil.

[0003] For example, the patent name is anti-theft fuel tank cover (patent number: 201220268031.1), which is set on the fuel tank and includes a fuel inlet, a lock body, an outer cover and a key, wherein an anti-pry step for installing the outer cover is set on the upper part of the inner wall of the fuel inlet, and the top of the anti-pry step is lower than the top of the fuel inlet. The outer cover presses the anti-pry step and is flush with or slightly concave to the top of the fuel inlet after installation; the key extends into the lock body through the unlocking hole on the outer cover, and controls the lock tongue to retract to open the fuel tank cover, and the lock tongue automatically extends back to lock the fuel tank cover through the set spring. The present invention has a simple structure, hides the fuel tank cover in the fuel inlet, effectively avoids the possibility of being easily pried open, and achieves the anti-theft effect. Although the invention has a certain anti-theft function, criminals can pry open the fuel tank cover by spending a certain amount of time and steal the gasoline in the fuel tank.

A spring 3 49 is arranged between the two telescopic plates 48. The spring 3 49 keeps the arc-shaped plates in an open state, and the two arc-shaped plates can be bent inward. Therefore, even if the lock body 4 is pried away by criminals, the driver can install the adapted lock body 4 into the barrel 5, and turn the key 7 to rotate the claw 44 to a specified position. After the claw 44 contacts the post 52 and turns inward to clamp the post 52, the key 7 can be turned again to open the sector plate 51 and the lock body 4. Even if the lock body 4 is pried away by criminals, the driver can still lock the fuel tank again. A plurality of parallel hemispherical bodies 6 are arranged on the two side surfaces of the box body 2, and a shell 1 is arranged on the outer side of the hemispherical bodies 6, and the shell 1 is fixedly connected to the box body 2, so that when an illegal person uses a drill to steal oil, the drill may be easily eccentric when it contacts the hemispherical bodies 6 after drilling into the shell 1, which increases the difficulty for the illegal person to use the drill to steal oil.

[0034] Working principle: When the truck anti-theft fuel tank is used, the driver installs the lock body 4 into the barrel body 5 and inserts the key 7 into the lock core 420. When the key 7 is inserted, the top block 43 is pressed downward, so that the top block 43 moves downward, so that the telescopic plate 48 moves outward, and the claw 44 on the telescopic plate 48 clamps the clamping column 52 on the rotating plate 53. At the same time, the sliding column 1 47 on the telescopic plate 48 enters the intersection of the linear sliding groove and the arc sliding groove of the sliding groove 3 417, and the key 7 is turned so that the notch 3 71 on the key 7 and the sliding column 2 415 on the guide rod 416 are locked. The guide plate 419 pulls the guide rod 416 and the slide column 417 along the arc-shaped slide groove of the slide groove 417, so that the telescopic plate 48 rotates at a certain angle and drives the rotation plate 53 to rotate, so that the fan-shaped plate 51 closes the barrel body 5, and the lock column 413 extends out of the shell 410 and inserts into the notch 54 on the barrel body 5 while turning the key 7, so that the lock body 4 is fixed on the barrel body 5. After the key 7 is pulled out, the top block 43 rises, and the guide plate 419 pulls the guide rod 416 back to the intersection of the arc-shaped slide groove and the linear slide groove in the slide groove 417, so that the slide column 47 follows the telescopic plate 48 to reset. When it is necessary to open the door, the driver inserts the key 7 into the lock cylinder 420 and turns the key 7 to retract the lock column 413, and turns the key 7 in the opposite direction again to drive the claw 44 to rotate to the clamping column 52, and clamps with the clamping column 52 again, and turns the key 7 in the opposite direction again to make the claw 44 drive the rotating plate 53 to rotate, so that the sector plate 51 is opened, and the key 7 can be pulled out to take out the lock body 4.
