Description

Technical Field

[0001] This utility model relates to the field of fuel dispensing technology, specifically a multi-functional metering refueling device. Background Technology

[0002] Multifunctional metering refueling equipment is a specialized device used in the fuel dispensing field for precise metering and delivery of fuels. This equipment can dispense various types of fuels, such as gasoline and diesel, in precise quantities. Its optimized connection structure ensures a stable and sealed refueling process. It is adaptable to various refueling scenarios, including vehicles and machinery, providing support for precise metering, safe delivery, and component maintenance. It is widely used in gas stations, logistics parks, construction sites, and other similar locations.

[0003] Traditional multi-functional metering refueling equipment has significant shortcomings in terms of maintenance of connecting components and leak prevention. Most equipment uses complex structures such as threaded or flanged connections for their connecting pipes, resulting in a single sealing method. After long-term use, oil seepage and leakage are prone to occur due to aging of the seals, leading to resource waste and safety hazards. When connecting components need to be replaced due to oil corrosion, multiple bolts or nuts must be removed using specialized tools such as wrenches, which is cumbersome and time-consuming, severely impacting maintenance efficiency. Furthermore, after replacing components, it is difficult to quickly restore a stable connection, easily leading to leaks again due to loose connections. This increases maintenance costs and fails to meet the requirements of "efficient maintenance and leak prevention" during refueling, making it difficult to guarantee the safety and continuity of refueling operations. Therefore, we propose a multi-functional metering refueling equipment. Utility Model Content

[0004] One of the technical problems this application aims to solve is that the existing oil refueling equipment has a complex connection structure, lacks sealing and the ability to quickly restore a stable connection, making it difficult to ensure the safety and continuity of refueling operations.

[0005] To address the aforementioned technical problems, this application provides a multifunctional metering refueling device, including a metering device. A display is located on one outer wall of the upper end of the metering device, and control buttons are located on both outer walls of the upper end of the metering device. A second connecting pipe is fixedly connected to one outer wall of the metering device. A groove is formed on one outer wall of the second connecting pipe, and a retaining ball is movably connected to one outer wall of the groove. A spring is movably connected to one outer wall of the groove. Multiple sealing grooves are formed on both sides of the inner wall of the second connecting pipe. A sleeve is movably connected to one outer wall of the second connecting pipe, and a limit ring is fixedly connected to one inner wall of the sleeve.

[0006] In some embodiments, a first connecting pipe is movably connected to one side of the inner wall of the second connecting pipe, and multiple sealing rings are fixedly connected to the outer walls on both sides of the first connecting pipe. A groove is provided on one side of the outer wall of the first connecting pipe, and an oil gun is fixedly connected to the outer wall of the first connecting pipe on the side away from the metering device. A connector is connected to the side of the metering device away from the oil gun, and a third connecting pipe is movably connected to the other side of the connector. An oil pump is connected to the side of the third connecting pipe away from the connector.

[0007] In some embodiments, the sealing ring on the outer wall of the first connecting pipe is connected to the sealing groove on the inner wall of the second connecting pipe.

[0008] In some embodiments, a limiting ring provided on one side of the inner wall of the sleeve is correspondingly connected to a sliding groove opened on one side of the outer wall of the second connecting pipe.

[0009] In some embodiments, a limiting ring provided on one side of the inner wall of the sleeve is located at the end of the spring near the retaining bead.

[0010] In some embodiments, a groove is formed on one side of the outer wall of the slide, and one side of the inner wall of the groove is movably connected to the retaining bead.

[0011] In some embodiments, the retaining beads provided on the sidewall of the slide are connected to the retaining grooves opened on the outer wall of one side of the first connecting pipe.

[0012] In some embodiments, a limiting ring provided on one side of the inner wall of the sleeve is correspondingly connected to a retaining bead provided on the outer wall of one side of the slide groove.

[0013] This utility model has at least the following beneficial effects: In use, this invention significantly optimizes the connection and maintenance process by optimizing the design of the first connecting pipe, second connecting pipe, sleeve, spring, retaining ball, sealing ring, and sealing groove, thus ensuring convenient maintenance and leak-proof sealing of the connecting components. When the first and second connecting pipes are connected, the multiple sealing rings on the outer wall of the first connecting pipe precisely fit with the sealing groove on the inner wall of the second connecting pipe, forming a multi-layered sealing structure. This effectively prevents oil leakage during refueling, reducing resource waste. When a component needs replacement due to corrosion from prolonged use, pushing the sleeve to one side causes it to slide along the outer wall of the second connecting pipe and compress the spring, disengaging the retaining ring from the retaining ball. After the retaining ball returns to its original position, the first connecting pipe can be easily pulled out for replacement. After replacement, the spring, through its reaction force, pushes the retaining ring back to its original position, causing the retaining ball to shift inward and lock the first connecting pipe, ensuring a secure connection. This convenient structure eliminates the need for complex tools, significantly shortening maintenance time and improving component replacement efficiency. In use, this invention leverages the coordinated efforts of the metering device, display, control buttons, oil pump, solenoid valve, and pulse device to ensure precise controllability and convenient data management during refueling operations. Users can select quantitative refueling, fixed-amount refueling, or free refueling modes and set parameters via the display. Upon receiving the command, the metering device controls the oil pump to start and the solenoid valve to open, while simultaneously receiving pulse signals from the pulse device in real time. When the refueling amount reaches the set value, the metering device immediately controls the solenoid valve to close and the oil pump to stop, achieving precise fuel cut-off and preventing over- or under-fueling. The display also shows the refueling amount, amount, and unit price in real time for easy and intuitive viewing. The metering device's built-in data storage module records the time, amount, and amount of each refueling transaction, supporting data export via USB and Bluetooth for compatibility with management systems, facilitating subsequent reconciliation and data statistics, and significantly improving the controllability and management efficiency of refueling operations.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0017] Example 1: Please refer to Figure 1-3This utility model provides a technical solution: a multi-functional metering refueling device, including a metering device 12, a display 13 on one outer wall of the upper end of the metering device 12, control buttons 14 on both outer walls of the upper end of the metering device 12, a second connecting pipe 5 fixedly connected to one outer wall of the metering device 12, a sliding groove 6 formed on one outer wall of the second connecting pipe 5, a retaining bead 7 movably connected to one outer wall of the sliding groove 6, a slot formed on one outer wall of the sliding groove 6, and one inner wall of the slot movably connected to the retaining bead 7, and one outer wall of the sliding groove 6 movably connected to the retaining bead 7. A spring 8 is connected to the second connecting pipe 5. Multiple sealing grooves 9 are opened on both sides of the inner wall of the second connecting pipe 5. A sleeve 10 is movably connected to one side of the outer wall of the second connecting pipe 5. A limiting ring 11 is fixedly connected to one side of the inner wall of the sleeve 10. The limiting ring 11 on one side of the inner wall of the sleeve 10 is correspondingly connected to the sliding groove 6 opened on one side of the outer wall of the second connecting pipe 5. The limiting ring 11 on one side of the inner wall of the sleeve 10 is located at the end of the spring 8 near the retaining bead 7. The limiting ring 11 on one side of the inner wall of the sleeve 10 is correspondingly connected to the retaining bead 7 on one side of the outer wall of the sliding groove 6.

[0018] In this embodiment, a metering device 12 is designed, with a display 13 and control buttons 14 respectively installed on the upper outer wall of the metering device 12. The display 13 can record the amount of refueling. The user can select "fixed quantity refueling" (e.g., 50L), "fixed amount refueling" (e.g., 300 yuan) or "free refueling" through the display 13 and set parameters. After receiving the command, the metering device 12 controls the oil pump 17 to start and the solenoid valve (controlling the oil circuit opening and closing) to open. At the same time, it receives the pulse signal of the pulse device inside the metering device 12 in real time. When the refueling amount reaches the set value, it immediately controls the solenoid valve to close and the motor to stop. At this time, the display 13 displays the current refueling amount, amount, and unit price (some devices display oil temperature). The data storage module inside the metering device 12 records each refueling record (time, amount, amount), and supports data export via USB / Bluetooth (adapting to the management system). The data storage module and the pulse device can be connected by bolts or other means. Built into one side of the inner wall of the measuring device 12, the installation method and position are not described in detail since no modifications are required. A second connecting pipe 5 is fixedly connected to the outer wall of one side of the measuring device 12. A groove 6 is opened on the outer wall of one side of the second connecting pipe 5, and a sleeve 10 is movably connected to the outer wall of one side of the second connecting pipe 5. A limiting ring 11 is provided on one side of the inner wall of the sleeve 10 and is correspondingly connected to the groove 6 opened on the outer wall of one side of the second connecting pipe 5. The limiting ring 11 is fixedly connected to one end of the spring 8. Therefore, when the sleeve 10 is pushed to one side, the sleeve 10 will slide on the outer wall of one side of the second connecting pipe 5 and squeeze the spring 8. Conversely, the spring 8 will apply a pushing force to the limiting ring 11, so that the limiting ring 11 is correspondingly connected to the locking beads 7 of the annular array on the outer wall of the groove 6, thereby shifting the locking beads 7 inward. This allows them to engage with the first connecting pipe 2 provided on the inner wall of the second connecting pipe 5, ensuring that the device can be quickly replaced after long-term use and corrosion.

[0019] Example 2: Please refer to Figure 1-4 The first connecting pipe 2 is movably connected to one side of the inner wall of the second connecting pipe 5. Multiple sealing rings 3 are fixedly connected to both outer walls of the first connecting pipe 2. The sealing rings 3 on the outer wall of the first connecting pipe 2 are connected to the sealing grooves 9 opened on the inner wall of the second connecting pipe 5. A slot 4 is opened on one side of the outer wall of the first connecting pipe 2. The retaining beads 7 on the side wall of the slide groove 6 are connected to the slot 4 opened on one side of the outer wall of the first connecting pipe 2. An oil gun 1 is fixedly connected to the outer wall of the first connecting pipe 2 away from the metering device 12. A connector 15 is connected to the side of the metering device 12 away from the oil gun 1. A third connecting pipe 16 is movably connected to the other side of the connector 15. An oil pump 17 is connected to the side of the third connecting pipe 16 away from the connector 15.

[0020] In this embodiment, a first connecting pipe 2 is movably connected to one side of the inner wall of the second connecting pipe 5. Multiple sealing rings 3 are provided on both outer walls of the first connecting pipe 2, and the sealing rings 3 on the outer wall of the first connecting pipe 2 can be connected to the sealing grooves 9 opened on the inner wall of the second connecting pipe 5. Therefore, during the infusion process, the sealing rings 3 and the sealing grooves 9 will seal the infusion and prevent leakage, thus avoiding waste of resources. An oil gun 1 is fixedly connected to the other side of the first connecting pipe 2. Therefore, through the connection between the first connecting pipe 2 and the second connecting pipe 5, the oil gun 1 can be used for oil filling. On the other side of the metering device 12, a third connecting pipe 16 is connected to the third connecting pipe 16 via a connector 15. An oil pump 17 is fixedly connected to the other side of the third connecting pipe 16. The oil pump 17 can perform oil suction to ensure stable output during the oil filling operation.
