The positioning groove 13 is located at the upper end of the closing groove 12. The closing plug 2 is slidably arranged in the closing groove 12 and can be adapted to be inserted into and pass through the positioning groove 13. The surface of the closing block 1 is provided with an arc-shaped sliding groove 121 communicated with the closing groove 12. The surface of the closing plug 2 is fixedly provided with a sliding rod 21. The sliding rod 21 is adapted to be slidably arranged in the sliding groove 121. The closing block 1 is provided with a mounting block 4 and a mounting bolt 41. The mounting bolt 41 is used to mount the mounting block 4 on the closing block 1. The mounting block 4 is L-shaped. The bottom wall of the mounting block 4 is integrally provided with a stopper 42 inserted into the positioning groove 13. The bottom wall of the stopper 42 is flush with the inner top wall of the closing groove 12 and can be against the outer wall of the closing plug 2. The closing block 1 is provided with a locking assembly 3 for locking the closing plug 2. When refueling, the contact locking assembly 3 is locked, and the sliding rod 21 is pushed to drive the closing plug 2 so that the closing plug 2 is separated from the positioning groove 13 and enters the closing groove 12. At this time, the closing plug 2 no longer closes the refueling pipe 11, and the refueling gun is inserted into the refueling pipe 11 for refueling. At this time, the closing plug 2 is located in the closing groove 12 and is against the inner wall of the closing groove 12, which reduces the possibility of the closing plug 2 being lost, thereby reducing damage and reducing the cost of reconfiguring the closing plug 2.

[0033] To improve the convenience of use, refer to Figure 2 and Figure 3The locking assembly 3 includes a locking support rod 33, a locking rod 31 and a locking spring 32. A locking groove 131 is provided on the inner wall of the positioning groove 13, the locking rod 31 is adapted and slidably arranged in the locking groove 131, the locking spring 32 is arranged in the locking groove 131, and the locking spring 32 is fixedly connected to the inner wall of the locking groove 131 and the side wall of the locking rod 31. A locking support groove 132 identical to the locking groove 131 is provided on the surface of the closing block 1, the locking support rod 33 is slidably arranged in the locking support groove 132 and is fixedly connected to the locking rod 31. A fixing groove 311 is provided at one end of the locking rod 31 away from the locking spring 32, into which the sliding rod 21 can be adapted and inserted.

Push the sliding rod 21 to move and drive the closing plug 2 to separate from the positioning groove 13 and enter the closing groove 12, thereby opening the refueling port and inserting the refueling gun into the refueling pipe 11 for refueling. Because the magnetic block is adsorbed, the locking rod 31 is located in the locking groove 131 and will not affect refueling. After refueling, push the sliding rod 21 to drive the closing plug 2 into the positioning groove 13 and close the refueling pipe 11. At this time, push the locking support rod 33 to separate the first magnetic block 133 and the second magnetic block 331. The locking spring 32 recovers and pushes the locking rod 31 to move so that the sliding rod 21 is inserted into the fixed groove 311, completing the locking. It is simple and convenient to use.

[0034] To improve the sealing performance, refer to Figure 2 The closing block 1 is provided with a circular sealing groove 14 connecting the refueling pipe 11 and the positioning groove 13.

By inserting the sealing block 22 into the sealing groove 14 and pressing the sealing pad 221 against the inner wall of the sealing groove 14, the sealing performance is improved, the possibility of gasoline or gasoline volatiles leaking through the refueling port is reduced, and the safety performance is improved.

[0035] The implementation principle of the fuel filler port sealing device for automobiles in the embodiment of the present application is as follows: when refueling is required, the locking support rod 33 is pushed until the first magnetic block 133 attracts the second magnetic block 331. During this process, the locking rod 31 moves and compresses the locking spring 32, and the sliding rod 21 is separated from the fixed groove 311. At this time, the sliding rod 21 is pulled to drive the closing plug 2 to move until the outer wall of the closing plug 2 abuts against the stopper 42. During this process, the sealing block 22 is separated from the sealing groove 14. At this time, the sliding rod 21 is pushed to drive the closing plug 2 to move out of the positioning groove 13 and into the closing groove 12, and move along the closing groove 12 under the action of gravity. At this time, the closing plug 2 The refueling pipe 11 is no longer sealed, and refueling can be carried out; when refueling is completed, the sliding rod 21 in the sliding groove 121 is pushed to drive the closing plug 2 to move into the positioning groove 13, and the closing plug 2 is pressed so that the sealing block 22 is inserted into the sealing groove 14 and the sealing pad 221 is pressed against the inner wall of the sealing groove 14, thereby closing the refueling pipe 11. At this time, the locking support rod 33 is pushed to separate the first magnetic block 133 from the second magnetic block 331, and the locking spring 32 is restored to push the locking rod 31 to move and press against the outer wall of the closing plug 2, and the sliding rod 21 is adapted to be inserted into the fixed groove 311 to complete the locking. At this time, the closing plug 2 closes the refueling pipe 11. By setting the closing groove 12, the closing plug 2 is in the closing groove 12 during refueling and will not be separated from the closing block 1, thereby reducing the possibility of the closing plug 2 being lost after being disassembled during the refueling process, thereby reducing damage and reducing the cost of reconfiguring the closing plug 2.

[0036] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
