Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.
[0021] It should be noted that when a component is referred to as "fixed to," "placed," "equipped with," "provided with," "arranged on," or "connected to" another component, it can be directly on the other component or may have an intervening component. When a component is considered to be "connected" to another component, it can be directly connected to the other component or may have an intervening component present.
[0022] It should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.
[0023] Please refer to Figures 1-6 The contents are shown to better understand the specific structure of this utility model. A mobile oil filling device according to a preferred embodiment of this utility model is shown below. Figure 1 As shown, it includes a liquid storage unit 1 and a filling unit 2. Furthermore, the liquid storage unit 1 and the filling unit 2 are connected by a pipeline.
[0024] Specifically, the liquid storage unit 1 is positioned above the filling unit 2 and can be fixed to each other by welding using rigid metal tubes. This connection method facilitates the overall movement and portability of the filling device.
[0025] Specifically, they can also be connected by a flexible hose, which makes it easy to remove and put in the liquid storage unit 1 and the filling unit 2 separately.
[0026] In this embodiment, the filling unit 2 is connected to the filling port of the equipment oil tank through a pipeline.
[0027] Specifically, a rubber hose can be used for connection. Since the filling port of some equipment fuel tanks is deep inside the components, the hose can be used to guide the fuel from the filling device to the filling port of the equipment fuel tank, avoiding the need to lift the filling device next to the filling port for filling.
[0028] In this embodiment, as Figure 2 As shown, the filling unit 2 includes a housing 201, an active part 202, and a driven part 203, used to transport the oil from the storage unit 1 to the equipment oil tank. The active part 202 and the driven part 203 cooperate with each other and are both disposed inside the housing 201.
[0029] Specifically, the filling unit 2 is a mechanical pump structure, which can be, but is not limited to, a gear pump, vane pump, plunger pump, or rotor pump. This utility model adopts a gear pump structure, wherein the driving part 202 and the driven part 203 are a pair of meshing driving gears and driven gears, respectively.
[0030] Specifically, the gear pump utilizes the tiny gaps formed between the gears and the inner wall of the housing 201 and the end cover to ensure both free rotation of the gears and the formation of a sealed working chamber. The gear pump achieves oil suction and pressure through the meshing and disengagement of the gears. During the suction process, when the driving gear drives the driven gear to rotate in the direction shown in the diagram, the gear teeth in the left suction chamber 204 gradually disengage, increasing the inter-tooth volume and creating a partial vacuum. The oil in the storage unit 1 then enters the suction chamber 204 through the pipeline under atmospheric pressure, filling the inter-tooth space. During the pressure process, the oil-filled inter-tooth space is carried to the right pressure chamber 205 as the gears rotate, causing the gear teeth to gradually engage. The inter-tooth volume decreases, the oil is squeezed out, and discharged from the pressure port, then transported through the pipeline to the equipment's filling port. Reverse rotation allows for reverse flow of the oil.
[0031] In this embodiment, as Figure 3 As shown, the active unit 202 is connected to the manual operation unit 3 located outside the housing 201.
[0032] Specifically, the drive unit 202 can be a gear shaft extending to the outside of the housing 201. The manual operation unit 3 can be a handle structure, with one end fixedly connected to the outside of the drive unit 202, such as by welding or screw connection.
[0033] In practical implementation, this utility model, by setting up a liquid storage unit 1, enables the refueling device to carry the corresponding oil and move to refuel the equipment, facilitating smooth daily maintenance; by setting up a refueling unit 2, the active part 202 and the driven part 203 can quickly refuel the equipment, saving a lot of time and manpower compared to manually pouring the oil; the refueling unit 2 is connected to the liquid filling port of the oil tank through a pipeline, which can avoid the problem of inconvenient refueling operation due to the liquid filling port being deep inside the component; the manual operation part 3 allows for convenient manual operation of the refueling unit 2, solving the problem of time-consuming and laborious equipment maintenance in the field when there is no external power.
[0034] In some embodiments, such as Figure 4 As shown, the filling unit 2 is equipped with a liquid suction port 206 and a liquid discharge port 207. The liquid suction port 206 is connected to the liquid outlet of the liquid storage unit 1. The liquid discharge port 207 is connected to the liquid filling port of the equipment oil tank through a pipeline.
[0035] Specifically, the suction port 206 corresponds to the oil suction chamber 204, and the discharge port 207 corresponds to the oil pressure chamber 205. This facilitates the smooth addition of oil.
[0036] In some embodiments, such as Figure 5 As shown, a speed-increasing mechanism 4 is provided between the drive unit 202 and the manual operation unit 3. The speed-increasing mechanism 4 is used to reduce the transmission ratio between the manual operation unit 3 and the drive unit 202.
[0037] Specifically, the speed-increasing mechanism 4 can be made of materials such as aluminum alloy, stainless steel, or cast iron, and can employ a planetary gear mechanism, a single-stage or double-stage gear transmission mechanism. In this embodiment, as shown... Figure 6 As shown, a planetary gear mechanism is used.
[0038] The planetary gear mechanism includes a sun gear 401, planet gears 402, a planet carrier 403, and a ring gear 404. In this embodiment, the ring gear 404 is fixed, the planet carrier 403 is the input, and the sun gear 401 is the output. The ring gear 404 is fixed to the housing 201 (this can be achieved by providing a blind hole 9 in the housing 201 and a protruding positioning pin 405 on the side of the ring gear 404 near the housing 201; the positioning pin 405 engages with the blind hole 9 to fix the ring gear 404). The sun gear 401 is connected to the driving unit 202, and the planet carrier 403 is connected to the manual operation unit 3. The working principle is that manually rotating the manual operation unit 3 drives the planet carrier 403-planet gear-sun gear 401-driving unit 202 to rotate, while the ring gear 404 remains fixed. The transmission ratio between the manual operation unit 3 and the drive unit 202 is the ratio of the number of teeth of the sun gear 401 to the number of teeth of the ring gear 404 (according to the transmission ratio formula of the planetary gear mechanism). Since the diameter of the ring gear 404 is larger than the diameter of the sun gear 401, and the number of teeth is also larger than that of the sun gear 401, the transmission ratio is less than 1, which can increase the speed.
[0039] In practice, setting up speed-increasing mechanism 4 can improve the refueling speed and further provide favorable conditions for equipment maintenance.
[0040] In this embodiment, as Figure 1 and Figure 3 As shown, the active unit 202 and the manual operation unit 3 are detachably connected; the speed-increasing mechanism 4 is also detachably connected to both the manual operation unit 3 and the active unit 202. Specifically, a connecting part 5 is provided on the portion of the active unit 202 extending outside the housing 201. The connecting part 5 is used for connection and positioning with the manual operation unit 3 and the speed-increasing mechanism 4.
[0041] Specifically, the connecting part 5 can be, but is not limited to, a gear meshing mechanism, a snap-fit mechanism, a spring positioning mechanism, or a magnetic attraction mechanism. In this embodiment, a magnetic attraction positioning mechanism is used.
[0042] Specifically, such as Figure 1 , Figure 3 and Figure 5As shown, a permanent magnet square-headed shaft is installed outside the active part 202. The manual operation part 3 and the speed-increasing mechanism 4 are also made of iron at the connection points with the rotating part, and corresponding square holes 10 are provided. The square-headed shaft is inserted into the square hole 10, which can both rotate and achieve positioning through magnetic attraction.
[0043] Furthermore, such as Figure 5 and Figure 6 As shown, a connecting part 5 with the same structure is provided at the position where the speed-increasing mechanism 4 is connected to the manual operation unit 3, which can realize a detachable connection with the manual operation unit 3.
[0044] In practice, a connecting part 5 is provided to enable detachable connection between the active part 202, the manual operation part 3, and the speed-increasing mechanism 4, facilitating the selection of whether speed-increasing refueling is needed under different conditions (such as when there is a lot of oil). This provides more convenient conditions for equipment maintenance.
[0045] In some embodiments, the dispensing device also includes a drive unit (not shown). The drive unit is detachably connected to the active unit 202.
[0046] Specifically, the drive unit can be an electric motor structure, such as an electric motor equipped with a rechargeable battery.
[0047] Specifically, the output shaft of the electric motor can be made into a square hole 10 structure that can cooperate with the connecting part 5.
[0048] In practice, when field conditions permit, electric refueling can be used, providing more options for equipment maintenance and further facilitating its operation.
[0049] In some implementations, such as Figure 1 As shown, the dispensing device also includes a support 6. The support 6 is located at the lower part of the dispensing unit 2 and is used to support the dispensing unit 2 and the liquid storage unit 1.
[0050] Specifically, the bracket 6 can be made of materials such as aluminum alloy, stainless steel, or cast iron, and can be fixedly connected to the lower part of the housing 201 of the dispensing unit 2 by bolts or welding, providing a stable support for the dispensing device.
[0051] In some implementations, such as Figure 1 As shown, the refueling device also includes an oil tank 7. The oil tank 7 is located at the bottom of the refueling device and is used to collect leaked oil.
[0052] Specifically, the oil tank 7 can be made of materials such as aluminum alloy, stainless steel, or cast iron. The bracket 6 can be placed directly inside the oil tank 7, or it can be fixedly connected by screws and welding.
[0053] In this embodiment, as Figure 1As shown, a traveling mechanism 8 is provided at the lower part of the oil tank 7. The traveling mechanism 8 is used to improve the mobility of the filling device.
[0054] Specifically, the walking mechanism 8 can be a roller structure made of metal, rubber or plastic, and is set at the four corners of the oil tank 7.
[0055] In practice, the oil tank 7 is installed to collect leaked oil and prevent environmental pollution. The walking mechanism 8 improves the mobility and maneuverability of the refueling device, providing more convenient conditions for equipment maintenance in the field.
[0056] In some embodiments, the liquid storage unit 1 has a barrel-shaped or funnel-shaped structure with an opening at the upper end and a liquid outlet at the lower end.
[0057] Specifically, during maintenance, oil can be poured into the reservoir unit 1 while simultaneously adding oil, acting as a funnel. Alternatively, it can be made into a barrel-shaped structure to store a certain amount of oil, facilitating mobile refilling of equipment. The reservoir unit 1 can be made of materials such as aluminum alloy, stainless steel, or cast iron.
[0058] Specifically, the storage unit 1 can be replaced with an oil pipe structure. Using an oil pipe, the suction port 206 can be directly connected to a larger capacity oil tank or drum, making it suitable for filling large oil tanks.
[0059] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention.

[0060] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
