[0002] A parking fuel generator is a portable or stationary power generation device, mainly used to provide electricity when the vehicle is stopped. Gasoline is a common fuel with a wide range of uses. However, adding gasoline to a parking fuel generator often requires manual addition, which is inconvenient. Therefore, a gasoline extraction device is needed.

[0003] Existing methods require users to manually fill a container with gasoline when adding fuel to a parking fuel generator, which is inconvenient. Connecting the extension tube to extract gasoline is also cumbersome, inefficient, and provides a poor refueling experience. Furthermore, the extension tube is difficult to disassemble. This new device simplifies the installation of the extension tube, is easy to operate, and automatically extracts gasoline, resulting in a better refueling experience for users and convenient disassembly of the extension tube. Utility Model Content

[0005] To achieve the above objectives, a gasoline extraction device for a parking fuel generator is provided, comprising: a chassis, a fixing box, a hexagonal flange nut, and a fuel tank. A gasoline interface is provided on the inner wall of the fixing box, and a reinforcing ring is provided on the outside of the gasoline interface. The side of the reinforcing ring is fixedly connected to the inner wall of the fixing box. Two collars are movably connected inside the reinforcing ring, and electric push rods are fixedly connected inside each of the two collars. A splicing ring is fixedly connected to the output end of each of the two electric push rods. A second metal contact piece is fixedly connected to the side of the fixing box, and a first metal contact piece is slidably connected to the outside of the gasoline interface. Multiple first springs are fixedly connected to the side of the fixing box, and one end of each of the multiple first springs is fixedly connected to the side of the first metal contact piece. A third metal contact piece is fixedly connected to the inner surface of the reinforcing ring. This facilitates pipe insertion by operators, allows for automatic fixing, and increases the convenience of refueling for users.

[0006] The reinforcing ring is fixedly connected to a second spring, and the end of the second spring is fixedly connected to a push block. The reinforcing ring is slidably connected to an insertion rod. The end of the insertion rod away from the push block is slidably connected to the inside of the collar, and the inner wall of the push block is slidably connected to the other end of the insertion rod, which facilitates the unloading of the inserted pipe.

[0007] According to the aforementioned gasoline extraction device for a parking fuel generator, a hexagonal flange nut is installed on the side of the generator housing. The generator housing is connected to a gasoline pump via the hexagonal flange nut. The output end of the gasoline pump is fixedly connected to a gasoline pipe (first type). The end of the gasoline pipe (first type) away from the gasoline pump is connected to the lower surface of the fuel tank. The input end of the gasoline pump is fixedly connected to a gasoline pipe (second type). The side of the generator housing is fixedly connected to the side of the gasoline extraction interface fixing box. A gasoline extraction switch is provided on the inner side wall of the gasoline extraction interface fixing box. The side of the gasoline interface is fixedly connected to the end of the gasoline pipe (second type) away from the gasoline pump. This device can automatically extract gasoline, reducing manual labor and improving the user's refueling experience.

[0008] According to the aforementioned gasoline extraction device for a parking fuel generator, the side of the generator casing is fixedly connected to the side of the fuel tank, and the upper surface of the fuel tank is provided with a fuel inlet. The fuel tank stores gasoline, which facilitates the operation of the device.

[0009] According to the aforementioned gasoline extraction device for a parking fuel generator, two splicing rings are symmetrically arranged, and the two splicing rings are the same in shape and size. The splicing rings can be used to increase the firmness when the gasoline interface is connected to other pipes.

[0010] According to the aforementioned gasoline pumping device for a parking fuel generator, the gasoline pump is equipped with fixing bolts that match the hexagonal flange nut, and the side of the splicing ring is slidably connected to the inner wall of the reinforcing ring, which facilitates the installation and disassembly of the gasoline pump and improves the convenience of the device.

[0011] According to the aforementioned gasoline extraction device for a parking fuel generator, the push block has an inclined surface inside, and the end of the insertion rod has an inclined surface that matches the push block, which facilitates the disassembly and installation of the electric push rod.

[0012] According to the aforementioned gasoline extraction device for a parking fuel generator, the splicing ring is arc-shaped, and the arc of the splicing ring matches the arc of the gasoline interface to maintain a fit and facilitate better fixation.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. During refueling, the user attaches the extension tube to the gasoline inlet. The extension tube pushes the first metal contact piece to contact the second metal contact piece, thereby causing the electric push rod to push the splicing ring to reinforce the connection between the extension tube and the gasoline inlet. After the extension tube is pulled out, the first spring pushes the first metal contact piece to contact the third metal contact piece, thereby controlling the electric push rod to retract. This automatically reinforces the connection between the extension tube and the gasoline inlet, reduces leakage, is easy to install, and improves the user's refueling experience.

[0015] 2. When it is necessary to disassemble the extension tube, press the push block. The inclined surface inside the push block cooperates with the inclined surface of the upper part of the insertion rod to push the insertion rod to move, thereby releasing the restriction of the insertion rod on the electric push rod, and thus releasing the electric push rod from fixing the extension tube. This facilitates the disassembly of the extension tube, has high working efficiency, good device convenience, and simple structure. The elasticity of the second spring pushes the push block to rise, and the inclined surface of the push block pushes the insertion rod to move, which can automatically fix the electric push rod and facilitate cyclic fixing.
