Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0028] Please refer to Figure 1 - Figure 6 As shown, the present utility model is an oil plug for an oil storage tank, including an oil plug body 1. The oil plug body 1 includes a head 101. A threaded section 102 is provided on the lower surface of the head 101. An installation groove 103 and a limiting groove 104 are opened on the upper surface of the head 101. One end of the installation groove 103 extends into the interior of the threaded section 102. An adjusting assembly 2 and a pressure relief assembly 3 are arranged inside the installation groove 103. A shielding assembly 4 is arranged on the upper surface of the head 101;

[0029] The adjusting assembly 2 includes a connecting block 201. A first spring 202 is installed on the lower surface of the connecting block 201, and the other end of the first spring 202 is installed on the inner bottom of the installation groove 103. A connecting plate 203 is hinged on the upper surface of the connecting block 201. A pin rod 204 is provided on the outer surface of the connecting plate 203. A guiding groove 105 is formed on the inner surface of the limiting groove 104, and the pin rod 204 is slidably connected to the inner surface of the guiding groove 105;

[0030] The shielding assembly 4 includes a cover body 401. A first connecting seat 402 is provided on the outer surface of the cover body 401. A second connecting rod 403 is provided on the inner top of the cover body 401. A limiting hole is formed on the upper surface of the connecting block 201, and the second connecting rod 403 is fitted and installed inside the limiting hole;

[0031] A limiting block 404 is provided on the lower surface of the first connecting seat 402. A second connecting seat 108 is provided on the outer surface of the head 101. An installation hole 109 is formed on the upper surface of the second connecting seat 108, and the limiting block 404 is fitted and installed inside the installation hole 109;

[0032] When installing the oil plug body 1, by removing the cover body 401 from the head 101, the limiting block 404 is disengaged from the installation hole 109. At the same time, the second connecting rod 403 cancels the fixation of the connecting block 201, so that the first spring 202 resumes its elasticity and pushes the connecting block 201 to move upward. When the connecting block 201 moves upward, the pin rod 204 slides in the guiding groove 105. At the same time, a part of the connecting plate 203 extends outward in the limiting groove 104. By installing the threaded section 102 into the oil inlet of the fuel tank and rotating the connecting plate 203 clockwise, the threaded section 102 is screwed into the oil inlet of the fuel tank to complete the installation of the oil plug body 1. After installing the oil plug body 1, pick up the cover body 401, align the first connecting seat 402 with the second connecting seat 108, and push the cover body 401 downward so that the limiting block 404 is fitted and installed inside the installation hole 109, and the second connecting rod 403 is fitted and installed inside the limiting hole of the connecting block 201. When the cover body 401 moves downward, the second connecting rod 403 will push the connecting block 201 to move downward in the installation groove 103, and the first spring 202 gradually contracts, so that the connecting plate 203 retracts into the installation groove 103;

[0033] A sealing groove 107 is formed on the lower surface of the head 101, and a sealing member 5 is fitted and installed inside the sealing groove 107;

[0034] During the screwing process of the oil plug body 1, the sealing member 5 will be continuously squeezed, so that the sealing member 5 seals the connection between the fuel tank and the oil plug body 1;

[0035] The pressure relief component 3 includes a plug body 301. A first connecting rod 302 is provided on the upper surface of the plug body 301.

An anti-disengagement block 303 is provided at the end of the first connecting rod 302 away from the plug body 301. A plurality of ventilation holes 106 are formed in the inner bottom of the installation groove 103. A second spring 304 is sleeved on the outer surface of the first connecting rod 302. One end of the second spring 304 is installed on the lower surface of the anti-disengagement block 303, and the other end of the second spring 304 is installed on the inner bottom of the installation groove 103;

[0036] When pressure relief is required in the fuel tank, by squeezing the anti-disengagement block 303 downward, the first connecting rod 302 provided on the lower surface of the anti-disengagement block 303 moves downward, thereby driving the plug body 301 to move downward. At the same time, the second spring 304 gradually contracts, so that the plug body 301 cancels the abutment with the threaded section 102, exposing the ventilation holes 106, and the gas flows to the outside through the ventilation holes 106, achieving the effect of reducing the pressure inside the fuel tank.
