Problems solved by technology

In the prior art, the fuel tank cap with anti-theft function and the fuel tank pipe are usually in one-piece structure, and if the fuel tank cap is damaged, it will be very inconvenient to replace
At the same time, the traditional fuel tank cap needs to be customized according to the size of the fuel tank pipe in the manufacturing process, so the manufacturing cost of the fuel tank cap with anti-theft function is very high, and the adaptability to the fuel tank pipe of different fuel tanks is poor

Embodiment 1

[0029] Please refer to Figure 1 to Figure 5 A specific embodiment of an anti-theft fuel tank cap of the present invention is shown. In this embodiment, the anti-theft fuel tank cap includes: an annular locking ring 10 and a cap body 20 . Both the lock ring 10 and the cover body 20 are circular and made of metal materials, such as aluminum-magnesium alloy and stainless steel.

[0030] The lock ring 10 is formed by inserting two horizontally engaged semi-circular rings, and an external thread 101 is provided on the outer surface of the periphery of the lock ring 10, and the lock ring 10 faces the annular surface 144 of the cover body 20 There is a lock 13 on it. Specifically, the lock ring 10 is formed by horizontally engaging a semi-circular ring 11 and a semi-circular ring 12 . The lock ring 10 is formed with a through hole 100 .

[0031] ginseng figure 1 As shown, when the anti-theft fuel tank cap is assembled on the fuel tank pipe 30 , the lock ring 10 is clamped on th...

Embodiment 2

[0045] Please refer to Figure 1 to Figure 4 as well as Figure 6 Another specific implementation manner of an anti-theft fuel tank cap of the present invention is shown. The main difference between this embodiment and the first embodiment is that in this embodiment, the locking member 13 further includes: a power source 133 electrically connected to the driving power module 132 . Specifically, the power supply 133 includes an alkaline battery, a lithium battery, a lead-acid battery or a lithium iron phosphate battery, and is preferably a lithium battery. Adopting this technical scheme can omit the wire. For other specific technical solutions in this implementation manner, please refer to the description in Embodiment 1, which will not be repeated here.

Abstract

The invention discloses an anti-theft fuel tank cap. The anti-theft fuel tank cap comprises a ring-shaped lock ring and a cap body, wherein the lock ring is formed by two horizontally-meshed semi-rings through insertion, external threads are arranged on the outer side surface of the peripheral edge of the lock ring, and a locking component is arranged on a ring surface, facing towards the cap body, of the lock ring; a blocking component and internal threads matched with the external threads are arranged on the side surface of the inner wall of the cap body; and a through hole of the lock ring is blocked through the relative rotation of the cap body and the lock ring, and the blocking component is limited by the locking component. According to the anti-theft fuel tank cap, after being separated, the lock ring can be clamped to the neck of a fuel tank pipe and is fixed through a fastening component, and the cap is rotated towards one direction and is limited through the locking component and the blocking component arranged on the side surface of the inner wall of the cap body, so that the rotation of the cap body towards an opposite direction is prevented, the adaptability of the traditional fuel tank pipe in an assembling process is realized, the manufacturing cost of the anti-theft fuel tank cap is lowered, and the rapid dismounting and mounting are realized.

Description

technical field [0001] The invention relates to the technical field of fuel tank caps, in particular to an anti-theft fuel tank cap. Background technique [0002] In order to realize the anti-theft function, the traditional fuel tank cap usually adopts a mechanical lock structure. The oil tank cap is locked and opened by using the key and the mechanical lock to cooperate with each other. In the prior art, the fuel tank cap and the fuel tank pipe with the anti-theft function are usually of an integrated structure, and if the fuel tank cap is damaged, it will be very inconvenient to replace it. At the same time, the traditional fuel tank cap needs to be customized according to the size of the fuel tank pipe during the manufacturing process, so the manufacturing cost of the fuel tank cap with anti-theft function is very high, and the adaptability to the fuel tank pipes of different fuel tanks is poor. [0003] In view of this, it is necessary to improve the oil tank cap based...
