[0028] Please refer to Figures 1 to 4 As shown, it shows the specific structure of a preferred embodiment of the utility model, including a cover base 10, a cover plate 20 and a lock head 30.

[0029] The cover seat 10 is a die-casting part, and the cover seat 10 is annular and has a refueling hole 11. In this embodiment, a positioning boss 12 is integrally extended downward from the bottom surface of one side of the cover seat 10, and the positioning boss 12 is used for positioning and assembling with the oil tank. The outer surface of the positioning boss 12 is concavely provided with a receiving groove 101, and the receiving groove 101 is provided with an axial hole 102. In addition, a plurality of fixing holes 103 are opened on the cover seat 10, and the plurality of fixing holes 103 are arranged at intervals so that the cover seat 10 and the oil tank can be fixedly installed. In addition, a positioning groove 104 is concavely provided on the other side surface of the cover seat 10.

[0030] The cover plate 20 is also a die-casting part. One side of the cover plate 20 is hinged to the cover seat 10. The cover plate 20 can be turned upside down relative to the cover seat 10. The cover plate 20 is turned upside down to open or close the refueling hole 11. In this embodiment, a mounting portion 21 extends from one side of the cover plate 20. The mounting portion 21 is located in the receiving groove 101. A shaft portion 201 extends from both sides of the mounting portion 21. The shaft portion 201 is hinged to the shaft hole 102. The structure is simple and the installation is stable. In addition, a positioning piece 22 extends from the other side of the cover plate 20. In the closed state, the positioning piece 22 is embedded in the positioning groove 104, so that the cover plate 20 and the cover seat 10 are firmly covered. In addition, a plurality of reinforcing ribs 23 are formed on the inner side surface of the cover plate 20 to make the structural strength of the cover plate 20 better.

[0031] The lock head 30 is disposed on the other side of the cover plate 20, and the inner end of the lock head 30 has a rotating buckle 31, which rotates back and forth to lock or unlock with the cover base 10. In this embodiment, the rotating buckle 31 is fixed to the inner end of the lock head 30 by a screw 32.

[0032] The method of using this embodiment is described in detail as follows:

[0033] When in use, the cover base 10 is fixed on the fuel tank opening of the fuel tank. In the original state, the cover plate 20 covers the fuel filling hole 11, and the rotating buckle 31 is locked with the inner side of the cover base 10. When the fuel filling hole 11 needs to be opened, a key is inserted into the lock 30 and the key is turned so that the rotating buckle 31 rotates and contacts the lock between the cover base 10. Then, the key is pulled upward to make the cover plate 20 flip upward relative to the cover base 10, thereby opening the fuel filling hole 11. At this time, the fuel tank can be refueled through the fuel filling hole 11. After refueling, the cover plate 20 is flipped downward relative to the cover base 10 so that the cover plate 20 covers the fuel filling hole 11, and then the key is turned in the opposite direction so that the rotating buckle 31 is locked with the inner side of the cover base 10, and finally the key is pulled out.

[0034] The design focus of the utility model is: by using die-casting for both the cover seat and the cover plate, the structural strength of the product is greatly enhanced and not easy to be damaged, and a lock is provided in combination, the lock drives the rotating buckle plate to rotate back and forth to lock or unlock with the cover seat, ensuring that the product is not easy to be lost / stolen when not in use, effectively reducing the risk of oil theft in the car, and bringing convenience to use.

[0035] The technical principle of the present invention is described above in combination with specific embodiments. These descriptions are only for explaining the principle of the present invention and cannot be interpreted as limiting the protection scope of the present invention in any way. Based on the explanations here, technicians in this field can think of other specific implementation methods of the present invention without creative work, and these methods will fall within the protection scope of the present invention.
