Specific embodiments
[0024] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. 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.
[0025] Please refer to Figures 1-5 , an anti-theft component for a fuel tank, including a mounting structure for fixedly installing at the fuel tank opening and driving lifting, and further including an adjustment structure disposed below the mounting structure for six-point synchronous lifting to adjust the plugging depth, and a plugging structure for plugging the inlet and capable of being unfolded downward to increase the plugging depth is installed on the adjustment structure.
[0026] In this embodiment: The mounting structure includes a mounting ring 101, a fixing ring 102 is disposed below the mounting ring 101, a motor 103 is disposed inside the fixing ring 102, a driving wheel 104 is installed below the motor 103, the fixing ring 102 is bolted to the mounting ring 101, the mounting ring 101 is adapted to the fuel tank inlet and can be fixed inside the fuel tank inlet, and the present component is installed at the fuel tank inlet through the mounting ring 101, and the fixing ring 102 supports the motor 103 to drive the driving wheel 104 to rotate to adjust the plugging depth;
[0027] In this embodiment, the adjustment structure includes a support ring 201, on which a toothed ring 202 is arranged. Six transmission wheels 204 are meshed inside the toothed ring 202. A lead screw 203 is installed inside the transmission wheel 204. Below the support ring 201, a lifting ring 206 is arranged. The lifting ring 206 is threadedly connected to the lead screw 203. A lower leakage net 207 is installed inside the lifting ring 206. Below the lifting ring 206, a limiting ring 205 is arranged. The lead screw 203 is rotatably connected to the support ring 201 and the limiting ring 205. The driving wheel 104 meshes with the toothed ring 202 to rotate. The toothed ring 202 then meshes with six transmission wheels 204 to drive six lead screws 203 to rotate under the support of the support ring 201, thereby pushing the lifting ring 206 to drive the lower leakage net 207 to move downward to the position of the limiting ring 205, changing the plugging depth.
[0028] In this embodiment, the plugging structure includes six first folding rods 301 arranged evenly. At the top of the first folding rod 301, a first hinge seat 302 is arranged. Below the first folding rod 301, a second folding rod 303 is arranged. At the bottom of the second folding rod 303, a second hinge seat 304 is arranged. A connecting seat 305 is installed between the first folding rod 301 and the second folding rod 303. A side leakage net 306 is arranged between adjacent two groups of the first folding rod 301 and the second folding rod 303. The adjacent first folding rod 301 and the second folding rod 303 are respectively hinged to the connecting seat 305. The side leakage net 306 is a soft net made of 206 stainless steel. During the downward movement of the lifting ring 206, the lifting ring 206 drives the second folding rod 303 to move downward through the second hinge seat 304. The second folding rod 303 then pulls the bottom of the first folding rod 301 to rotate downward around the first hinge seat 302 through the connecting seat 305, flattening the side leakage net 306 downward, increasing the plugging depth, so that the fuel gun can smoothly extend into the fuel tank for refueling.
[0029] Working principle: The installation ring 101 is adapted to the fuel tank inlet and is fixed inside the fuel tank inlet. This component is installed at the fuel tank inlet through the installation ring 101. The fuel tank inlet is plugged by the side leakage net 306 and the lower leakage net 207 to prevent external pipelines from extending into the fuel tank to steal oil. When refueling is needed, the fixed ring 102 supports the motor 103 to drive the driving wheel 104 to mesh with the toothed ring 202 to rotate. The toothed ring 202 then meshes with six transmission wheels 204 to synchronously drive six lead screws 203 to rotate under the support of the support ring 201, thereby pushing the lifting ring 206 to drive the lower leakage net 207 to move downward to the position of the limiting ring 205 from six points simultaneously. During this process, the lifting ring 206 drives the second folding rod 303 to move downward through the second hinge seat 304. The second folding rod 303 then pulls the bottom of the first folding rod 301 to rotate downward around the first hinge seat 302 through the connecting seat 305, flattening the side leakage net 306 downward, increasing the plugging depth, so that the fuel gun can smoothly extend into the fuel tank for refueling.
[0030] Although the embodiments of the present invention have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
