[0025] To make the above objects, features, and advantages of the present utility model more apparent and understandable, the following detailed description of the specific embodiments of the present utility model will be given with reference to the accompanying drawings of the specification.

[0026] Refer to Figures 1-4, which is the first embodiment of the present utility model, provides a highly stable double-layer thick-wall oil tank head, including a head body 1. An auxiliary plate 2 is fixedly connected to the bottom of the head body 1. The shape of the auxiliary plate 2 is an "annular" structure. When installing the head body 1, inserting the auxiliary plate 2 into the interior of the oil tank can align the head body 1 with one end of the oil tank, facilitating the welding work of the head body 1 and avoiding the situation of the head body 1 being skewed during the welding of the head body 1.

[0027] A reinforcement plate 3 is fixedly connected to the outer wall of the head body 1. An air groove 4 is formed on the front surface of the head body 1. A triangular steel frame 7 is fixedly connected to the inner wall of the air groove 4. Both the reinforcement plate 3 and the triangular steel frame 7 are made of very hard materials, which can effectively play a role in anti-collision.

[0028] A pressure regulating channel 5 is formed on the inner wall of the head body 1. A polytetrafluoroethylene layer 6 is fixedly connected to the inner wall of the pressure regulating channel 5. A through groove 8 is formed on the inner wall of the air groove 4. A magnetic plate 9 is fixedly connected to the inner wall of the through groove 8. A first ventilation hole 10 is formed at the bottom of the magnetic plate 9, which enables the magnetic plate 9 to be ventilated.

[0029] The inner wall of the through groove 8 is an inclined surface. A sealing plug 17 is slidably connected to the inner wall of the through groove 8. A magnetic block 18 is fixedly connected to the bottom of the sealing plug 17. Both the magnetic plate 9 and the magnetic block 18 have magnetism, and the magnetic block 18 attracts the magnetic plate 9. A groove 11 is formed on the inner wall of the reinforcement plate 3, and a second ventilation hole 12 is formed on the inner wall of the groove 11, which can play a role in ventilation.

[0030] During the use process, step one: when the pressure inside the oil tank becomes small, since the polytetrafluoroethylene layer 6 is a common elastic sealing material, the polytetrafluoroethylene layer 6 will bulge into the interior of the head body 1, and then compress the air inside the head body 1;

[0031] Step two: when the pressure inside the oil tank becomes large, the polytetrafluoroethylene layer 6 will bulge into the interior of the air groove 4. The air pressure inside the air groove 4 will squeeze the sealing plug 17, and the sealing plug 17 will move. Then, there will be a gap between the outer wall of the sealing plug 17 and the interior of the through groove 8. Then, air can escape through the second ventilation hole 12, making the interior space of the oil tank larger. Thus, it can be realized that during the use process of the head body 1, the internal air pressure can be adjusted according to the thermal expansion and contraction state of the oil in the oil tank.

[0032] Refer to Figures 1-4 , which is the second embodiment of the present utility model. A sliding rod 14 is fixedly connected to the top of the sealing plug 17. A limiting plate 15 is fixedly connected to the top of the sliding rod 14. A spring 16 is fixedly connected to the top of the sealing plug 17.

[0033] A chute 13 is provided on the inner wall of the groove 11, a sliding rod 14 is slidably sleeved with the chute 13, and one end of a spring 16 is fixedly connected to the inner wall of the groove 11.

[0034] During use, when the air pressure inside the oil tank is in a balanced state, the sealing plug 17 will be reset by the elastic force of the spring 16. Furthermore, the sealing plug 17 can block the first ventilation hole 10 again. Since both the magnetic plate 9 and the magnetic block 18 have magnetic force, when the sealing plug 17 approaches the magnetic plate 9, the magnetic block 18 and the magnetic plate 9 are attracted to each other through magnetic attraction. Furthermore, the sealing plug 17 can tightly block the through groove 8.

[0035] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and not to limit them. Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present invention can be modified or equivalently replaced without departing from the spirit and scope of the technical solutions of the present invention, and they should all be covered within the scope of the claims of the present invention.
