BRIEF DESCRIPTION OF DRAWINGS

[0009] The utility model will be further explained in detail in combination with the drawings and specific embodiments.

[0010] Figure 1 It is a structural schematic view of the utility model.

[0011] Figure 2 It is Figure 1 It is an enlarged view of A in the middle. EMBODIMENT

[0012] For example, Figure 1A novel refueling port sealing structure is shown, comprising a refueling guide pipe 3, an outer valve body 1, an annular support seat 11, a valve core 6, an outer cover 2, and an inner cover 13. One end of the refueling guide pipe is connected to the refueling port. One end of the outer valve body is slidably connected to the outer wall of the refueling guide pipe via a sliding seat. The annular support seat is disposed on the outer wall of the refueling guide pipe behind the outer valve body and is integrally connected to it. The other end of the refueling guide pipe extends into the outer valve body. The other end of the outer valve body is detachably connected to the outer cover. The end of the refueling guide pipe extending into the outer valve body is detachably connected to the inner cover. The inner cover is provided with a pull handle. The valve core is piston-type connected between the outer wall of the refueling guide pipe and the inner wall of the outer valve body. An oil inlet hole 7 is opened on the side wall of the refueling guide pipe. The oil inlet hole is sealed by the valve core. A first spring 8 is provided between the valve core and the outer valve body. The outer valve body is connected to the annular support seat via a second spring 9. When refueling is needed, first remove the outer cover, then press the outer valve to extend the refueling tube. At this point, remove the inner cover, then release the outer valve and insert the refueling nozzle into the refueling tube for refueling. When not in use, the refueling tube automatically retracts into the outer valve, which protects both the tube and the inner cover. Furthermore, when refueling outdoors, where a dedicated refueling nozzle is unavailable, a straight object can be inserted into the outer valve to open the inlet hole by squeezing, allowing refueling to be poured out. Gasoline can flow directly into the tank through the refueling tube or through the inlet hole, increasing usability and reducing unnecessary gasoline waste.

[0013] like Figure 1 The annular support shown has a threaded through hole, into which an adjusting bolt 12 is connected. The adjusting bolt passes through the threaded through hole and is movably connected to the adjusting plate 10. The adjusting plate is annular, and its inner diameter matches the outer diameter of the refueling guide pipe. The adjusting plate can slide along the refueling guide pipe. The outer valve body is connected to the adjusting plate via a second spring. This invention allows for adjustment of the initial spring force of the second spring through this structure.

[0014] like Figure 1 The outer cover shown has a first pull ring structure, and the outer wall of the outer valve body has a second pull ring structure. The first pull ring structure is connected to the second pull ring structure by a rope. This structure effectively prevents the outer cover from being accidentally lost, thus increasing its practicality.

[0015] like Figure 1 and Figure 2The inner cover body is provided with an annular protruding part for sealing the oiling guide pipe, the annular protruding part extends into the oiling guide pipe from the port of the oiling guide pipe, and an elastic clamping mechanism is further arranged between the annular protruding part and the oiling guide pipe, the elastic clamping mechanism comprises a semispherical clamping groove arranged on the inner wall of the oiling guide pipe, a connecting hole arranged on the outer wall of the annular protruding part, a spherical clamping head 14 and a third spring 15, the spherical clamping head is connected in the connecting hole through the third spring, and the spherical clamping head is clamped into the semispherical clamping groove under the action of the third spring. The design has the advantages of simple structure, easy manufacturing and high efficiency.
