Description

Technical Field

[0001] The utility model relates to the technical field of refueling devices, in particular to a mobile hand-cranked refueling device. Background Art

[0002] With the development of the times and the advancement of technology, more and more people choose to travel in their spare time. Whether it is a long journey such as self-driving or yachting, the battery life of the travel tool cannot be ignored. Therefore, when the journey is long and it is impossible to refuel in the middle, you need to prepare a fuel tank in advance. When necessary, add the fuel in the storage tank to the fuel tank of the vehicle, which requires the use of a refueling device.

[0003] When the existing refueling device is in use, it is necessary to plug the refueling device into the oil storage tank, then extract the oil in the oil storage tank, and then transfer the extracted oil to the oil tank for pouring and refueling, finally completing the refueling work.

[0004] The existing refueling device needs to transfer the extracted gasoline through a small bucket or other tools after pumping out the gasoline. The refueling device cannot directly connect the oil storage tank and the oil tank, and the transfer in the middle may cause gasoline waste, which is more cumbersome to use. Utility Model Content

DETAILED DESCRIPTION

[0026] The technical solutions in the embodiments of the present invention will be described clearly and completely below with reference to the accompanying drawings in the embodiments of the present invention.

[0027] Example 1

[0028] Reference Figure 1 、 Figure 2 and Figure 3 , which is the first embodiment of the present utility model, provides a mobile hand-cranked refueling device, including a chassis 1, an extraction component 2 is provided inside the chassis 1, an oil inlet pipe 6 is provided on one side of the chassis 1, an oil outlet pipe 3 is provided on the side of the chassis 1 away from the oil inlet pipe 6, and a docking component 5 is provided at the end of the oil outlet pipe 3 away from the chassis 1, the extraction component 2 includes an inner cylinder 204 fixedly connected to the inside of the chassis 1, a rotating block 203 is movably connected inside the inner cylinder 204, one side of the rotating block 203 is fixedly connected to a connecting block 201, one end of the connecting block 201 passes through the chassis 1 and is fixedly connected to a rotating rod 202, two push plates 207 are slidably connected to the inside of the rotating block 203, a spring 206 is fixedly connected between the two push plates 207, and a movable rod 205 is inserted into the push plate 207.

[0029] Specifically, the center of rotation of the rotating block 203 is located directly below the center of the inner cylinder 204. The length of the two push plates 207 plus the outer length of the spring 206 is sufficient for the push plate 207 to keep one end away from the spring 206 in contact with the inner wall of the inner cylinder 204. The rotating rod 202 drives the rotating block 203 to rotate clockwise, the oil inlet pipe 6 is connected to the inner cylinder 204, and a cavity is left between the rotating block 203 and the inner cylinder 204.

[0030] The push plates 207 are limited by the movable rod 205 inserted therein, and the spring 206 keeps the two push plates 207 away from the end of the spring 206 and in contact with the inner wall of the inner cylinder 204. The rotation of the rotating cylinder drives the push plates 207 to rotate, and the interior of the inner cylinder 204 is divided into two cavities by the push plates 207 and the rotating block 203. As the rotating cylinder is driven by the rotating rod 202 to rotate clockwise through the rotating block 203, the cavity on the left side of the inner cylinder 204 gradually becomes larger, thereby reducing the pressure of the cavity on the right side, thereby sucking out the gasoline inside the oil storage tank through the oil inlet pipe 6 and the hose. As the rotating block 203 rotates, the cavity on the left side gradually rotates to the right side, and as the push plates 207 rotate, the cavity containing gasoline gradually becomes smaller, thereby driving the gasoline to be discharged through the oil outlet pipe 3.

[0031] Example 2

[0032] Reference Figure 1 and Figure 4 , which is the second embodiment of the present utility model, and is based on the previous embodiment. The docking assembly 5 includes a support block 504 fixedly connected to the end of the oil outlet pipe 3 away from the chassis 1, and an insert tube 502 is fixedly connected to the side of the support block 504 away from the oil outlet pipe 3. An insert tube 503 is inserted into the interior of the support block 504, and a docking rubber ring 501 is fixedly connected to the outer surface of the support block 504.

[0033] Specifically, a handle 4 is provided on the upper surface of the chassis 1 , the oil outlet pipe 3 is connected to a side of the inner cylinder 204 away from the oil inlet, and the plug-in pipe 503 is connected to the oil outlet pipe 3 .

[0034] Furthermore, the plug-in tube 503 is inserted into the oil inlet of the fuel tank, and the plug-in tube 503 and the oil inlet of the fuel tank are sealed by the plug-in tube 502, and the support block 504 is in contact with the oil inlet to provide support for the entire device. The oil inlet is covered by the docking rubber ring 501 to prevent dust or other impurities from entering the fuel tank. The material of the plug-in tube 502 is soft material, so that after the plug-in tube 503 is inserted into the oil inlet of the fuel tank, the gap between the oil inlet and the plug-in tube 503 can be sealed by the deformation of the plug-in tube 502.

[0035] Working principle: When the fuel tank needs to be refueled, the chassis 1 is extracted through the handle 4, and the oil inlet and the fuel tank are connected through a hose, and then the plug-in tube 503 is inserted into the oil inlet position of the fuel tank, and the plug-in tube 503 and the oil inlet position of the fuel tank are sealed through the plug-in tube 502, and the support block 504 is in contact with the oil inlet position to provide support for the entire device, and the oil inlet position is covered by the docking rubber ring 501 to prevent dust or other impurities from entering the fuel tank, and then the rotating rod 202 is rotated, and the rotating block 203 is driven to rotate through the connecting block 201, and the rotating block 203 drives the two internal push plates 207 to rotate, and the push plates 207 are limited by the movable rod 205 inserted inside, and the two push plates 207 are kept away from the inner wall of the inner cylinder 204 by the action of the spring 206. The push plate 207 is driven to rotate, and the interior of the inner cylinder 204 is divided into two cavities through the push plate 207 and the rotating block 203. As the rotating rod 202 drives the rotating cylinder to rotate clockwise through the rotating block 203, the cavity on the left side of the inner cylinder 204 gradually becomes larger, thereby driving the pressure of the cavity on the right side to decrease, thereby sucking out the gasoline inside the oil storage tank through the oil inlet pipe 6 and the hose. As the rotating block 203 rotates, the cavity on the left side gradually rotates to the right, and as the push plate 207 rotates, the cavity containing gasoline gradually becomes smaller, thereby driving the gasoline to be discharged through the oil outlet pipe 3, and then enter the fuel tank through the plug-in pipe 503. This reciprocating process finally realizes the refueling work, and the chassis 1 can be extracted for convenient refueling. By docking the docking component 5 with the fuel filling port of the fuel tank, the support block 504 provides support, which facilitates the extraction component 2 to extract gasoline.
