Two sets of vertical blocks are fixed to the top wall of the inner cavity of the fitting slot. The lower ends of the two sets of vertical blocks are provided with embedding slots.

[0007] Furthermore, the outer wall of the boss ring abuts against the inner wall of the fitting slot.

[0008] Furthermore, both sets of the first strong magnetic blocks are fixed to the bottom wall of the inner cavity of the connecting slot, and the first strong magnetic blocks penetrate through the interior of the through hole and are fixed thereto.

[0009] Furthermore, the top ends of both sets of the second strong magnetic blocks are fixed to the top wall of the embedded slot cavity.

[0010] Furthermore, the two sets of first strong magnetic blocks correspond to the two sets of second strong magnetic blocks, and the distance between the first strong magnetic blocks and the second strong magnetic blocks is 0.5 mm.

[0011] Furthermore, the hinge seat is installed on the right side of the top of the fixing ring, the hinge groove is opened on the right side of the lower end of the cover plate, the hinge seat is located inside the hinge groove and is hinged to it, the four L-shaped mounting plates are evenly fixed around the fixing ring on opposite sides, and the four mounting holes are opened on opposite sides of the four L-shaped mounting plates.

[0012] Furthermore, the top of the cover plate is spherical, and the left side wall of the cover plate has an opening groove for opening.

[0013] Compared with the prior art, the technical solution of this application has the following beneficial effects:

Detailed Implementation

[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0022] Please see Figures 1 to 5 The oil tank cover in this embodiment is not prone to leakage, including an oil tank cover body 1. The oil tank cover body 1 includes a fixing ring 11, a cover plate 12, four L-shaped mounting plates 13, four mounting holes 14, a hinge seat 15 and a hinge groove 16. A sealing structure is provided between the fixing ring 11 and the cover plate 12.

[0023] Furthermore, the hinge seat 15 is installed on the right side of the top of the fixing ring 11, and the hinge groove 16 is opened on the right side of the lower end of the cover plate 12. The hinge seat 15 is located inside the hinge groove 16 and is hinged to it so that the fixing ring 11 and the cover plate 12 can be connected together. The four L-shaped mounting plates 13 are evenly fixed around the fixing ring 11 on opposite sides. The four mounting holes 14 are opened on opposite sides of the four L-shaped mounting plates 13 so that the tank cover body 1 composed of the fixing ring 11 and the cover plate 12 can be installed and fixed with external equipment.

[0024] Please see Figures 1 to 5 The sealing structure in this embodiment includes a boss ring 21 fixed to the top of the fixing ring 11. Two first strong magnetic blocks 22 are provided at the front and rear ends of the top of the boss ring 21. A second strong magnetic block 28 is provided at the top of the two sets of first strong magnetic blocks 22. The sealing structure also includes two connecting slots 23 opened on the front and rear sides of the top of the fixing ring 11. Two through holes 24 are opened at the front and rear ends of the top of the boss ring 21. The sealing structure also includes a fitting slot 25 opened at the lower end of the cover plate 12. Two sets of vertical blocks 26 are fixed to the top wall of the inner cavity of the fitting slot 25. An embedding slot 27 is opened at the lower end of the two sets of vertical blocks 26.

[0025] The outer wall of the boss ring 21 abuts against the inner wall of the fitting slot 25, which can block the gap between the fixing ring 11 and the cover plate 12, making it difficult for external water to enter through the gap, thus effectively improving the waterproof effect.

[0026] In addition, both sets of first strong magnetic blocks 22 are fixed to the bottom wall of the inner cavity of the connecting slot 23. The first strong magnetic block 22 passes through the interior of the through hole 24 and is fixed thereto. The first strong magnetic block 22 is fixed in the fixing ring 11 through the connecting slot 23 and can pass through the interior of the boss ring 21 through the through hole 24 so that it can be magnetically attracted to the second strong magnetic block 28.

[0027] Meanwhile, the tops of the two sets of second strong magnetic blocks 28 are fixed to the top wall of the cavity of the embedded slot 27, so that the second strong magnetic blocks 28 can be embedded in the vertical block 26 so that they can be fixed on the cover plate 12.

[0028] Furthermore, the two sets of first strong magnetic blocks 22 correspond to the two sets of second strong magnetic blocks 28. The fixing ring 11 and the cover plate 12 can be fixed together by the two sets of first strong magnetic blocks 22 and the two sets of second strong magnetic blocks 28, so that the cover plate 12 is not easy to jump up or be shaken open during vehicle operation. The distance between the first strong magnetic blocks 22 and the second strong magnetic blocks 28 is 0.5MM, which always ensures that there is an adsorption force between the cover plate 12 and the fixing ring 11, so as to ensure that they are in a sealed state and that water is not easy to seep in.

[0029] In addition, the top of the cover plate 12 is spherical, so that when water drips onto the cover plate 12, the water can slide off the cover plate 12 due to the shape of the top, and water is not easy to accumulate. The left side wall of the cover plate 12 is provided with an opening groove 17 for opening, which facilitates opening the fuel tank cover body 1.

[0030] Furthermore, the fixing ring 11, cover plate 12, L-shaped mounting plate 13, boss ring 21 and vertical block 26 are all made of 6-series aluminum alloy, which can effectively improve service life and is not easy to age or become brittle. The top surface of the cover plate 12 is sandblasted and oxidized, which is not easy to fade and is corrosion resistant, thus extending its service life.

[0031] The working principle of the above embodiments is as follows:

[0032] In use, the boss ring 21 and the fitting groove 25 can block the gap between the fixing ring 11 and the cover plate 12, thus preventing external water from easily seeping into the fuel tank cover body 1. The fixing ring 11 and the cover plate 12 are fixed together by strong magnetic attraction through two sets of first strong magnetic attraction blocks 22 and two sets of second strong magnetic attraction blocks 28, so as to ensure that they are in a sealed state and that water is not easy to seep in. This can effectively improve the waterproofness of the fuel tank cover body 1. Furthermore, the top of the cover plate 12 is spherical, so when water drips onto the cover plate 12, the water can slide off the cover plate 12 due to the shape of the top, and water is not easy to accumulate.
