[0016] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0017] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.

[0018] Example

[0019] Reference Figure 1-4 This embodiment of the present invention provides an anti-loosening structure for a fuel tank door opening cable assembly, comprising: The fuel tank mechanism 100 includes a fuel tank 110, an oil inlet 120 fixedly installed on the surface of the fuel tank 110, and a fuel tank cover 130 hinged to the surface of the fuel tank 110 and used to close the oil inlet 120. The anti-loosening mechanism 200 includes a snap-fit ​​component 210 for snapping the fuel tank cap 130, and an anti-loosening component 220 for preventing the fuel tank cap 130 from becoming loose.

[0020] The snap-fit ​​component 210 is used to snap the fuel tank cap 130 in place, thereby improving the closing stability of the fuel tank cap 130 at the top of the fuel inlet 120. The anti-loosening component 220 is used to prevent the fuel tank cap 130 from coming loose from the top of the fuel inlet 120 under vibration, thus preventing it from affecting the normal use of the fuel tank 110.

[0021] Specifically, the snap-fit ​​component 210 includes an inner box 211 fixedly installed on the inner wall of the oil inlet 120, a snap-fit ​​block 212 elastically installed inside the inner box 211, and a mating block 213 fixedly installed on the surface of the fuel tank cap 130 and used in conjunction with the snap-fit ​​block 212 to snap and limit the engagement of the fuel tank cap 130.

[0022] The spring 215 is used to press the transmission rod 216, which in turn pushes the locking block 212 to maintain its movement, so that the locking block 212 and the docking block 213 lock together, thereby locking and limiting the oil tank cap 130 and improving the closing stability of the oil tank cap 130 at the top of the oil inlet 120.

[0023] Furthermore, the snap-fit ​​component 210 also includes an outer casing 214 fixedly installed on the outside of the oil inlet 120, two snap-fit ​​springs 215 fixedly installed inside the outer casing 214, and a transmission rod 216 fixedly installed between the snap-fit ​​block 212 and the snap-fit ​​springs 215.

[0024] Preferably, the transmission rod 216 and the snap-fit ​​spring 215 are fixedly connected by a connecting rod, and an anti-loosening rod 217 is fixedly installed on one side of the connecting plate.

[0025] Furthermore, the anti-loosening component 220 includes a baffle 221 fixedly installed on the surface of the fuel tank cap 130, a threaded block 222 threadedly installed on the baffle 221 and used to abut against the end of the anti-loosening rod 217, and a torsion plate 223 fixedly installed on the surface of the threaded block 222.

[0026] The baffle 221 and the threaded block 222 are used to abut and limit the end of the anti-loosening rod 217, preventing the anti-loosening rod 217 from shifting and causing the locking block 212 and the mating block 213 to loosen.

[0027] Specifically, the surface of the baffle 221 is provided with a threaded groove 224, and the threaded block 222 is threadedly installed inside the threaded groove 224.

[0028] The threaded groove 224 is used to connect the threaded block 222 to the threaded block 222, thereby facilitating the threaded block 222 to abut and limit the end of the anti-loosening rod 217 and prevent it from loosening.

[0029] Furthermore, a connecting groove is provided between the baffle 221 and the outer casing 214, and the transmission rod 216 passes through the connecting groove.

[0030] The connecting groove is used to limit the movement of the transmission rod 216, thereby improving the stability of the movement of the transmission rod 216.

[0031] In use, the snap-fit ​​spring 215 presses the transmission rod 216, which in turn pushes the snap-fit ​​block 212 to maintain its movement, so that the snap-fit ​​block 212 and the docking block 213 snap into each other, thereby snapping and limiting the oil tank cap 130. The engagement between the baffle 221 and the threaded block 222 provides abutment and limit to the end of the anti-loosening rod 217, preventing the anti-loosening rod 217 from shifting and causing loosening between the locking block 212 and the mating block 213.

[0032] In summary, the snap-fit ​​component 210 is used to snap the fuel tank cap 130 in place, thereby improving the closing stability of the fuel tank cap 130 at the top of the fuel inlet 120. The anti-loosening component 220 is used to prevent the fuel tank cap 130 from coming loose from the top of the fuel inlet 120 under vibration, thus preventing it from affecting the normal use of the fuel tank 110.
