Description

Technical Field

[0001] This utility model relates to the field of oil changing equipment, and in particular to an oil receiving hopper. Background Technology

[0002] In the process of changing lubricating oil in industrial equipment or vehicles, the traditional operation relies on measuring the amount of lubricating oil with a measuring cup: first, the lubricating oil is poured into the measuring cup, then the opening of the measuring cup is manually sealed. An external air pressure device is used to increase the air pressure inside the measuring cup, causing the lubricating oil to be discharged from the measuring cup and injected into the equipment. After each oil filling, the measuring cup must be manually sealed, and after draining the oil, the sealing structure must be disassembled before oil can be filled again. The repeated sealing, unsealing, and venting operations are cumbersome, especially when changing oil in a large number of pieces of equipment, which consumes time and manpower, resulting in low oil changing efficiency. In some cases, poor sealing can even cause air pressure leakage and poor oil drainage, further affecting the work progress. Utility Model Content

[0007] As a further improvement to the above technical solution, a second sealing ring is also included. A second groove is provided on the sealing surface of the thrust head, and the second sealing ring is disposed in the second groove. When the sealing surface of the thrust head abuts against the lower end surface of the retaining ring, the second sealing ring is compressed and sealed between the sealing surface of the thrust head and the lower end surface of the retaining ring.

[0008] As a further improvement to the above technical solution, it also includes a dust cover and a hinge shaft. One end of the dust cover is hinged to the funnel via the hinge shaft, and the dust cover can rotate around the hinge shaft to cover or open the entrance of the funnel.

Obviously, the described embodiments are only a part of the embodiments of this utility model, not all of them.

Furthermore, all connections / linkages mentioned herein do not simply refer to direct contact between components, but rather to the ability to form a better connection structure by adding or reducing connecting accessories according to specific implementation conditions. The various technical features in this utility model can be combined interactively without contradicting each other.

[0020] In the process of changing lubricating oil in industrial equipment or vehicles, the traditional operation relies on measuring the amount of lubricating oil with a measuring cup: first, the lubricating oil is poured into the measuring cup, then the opening of the measuring cup is manually sealed. An external air pressure device is used to increase the air pressure inside the measuring cup, causing the lubricating oil to be discharged from the measuring cup and injected into the equipment. After each oil filling, the measuring cup must be manually sealed, and after draining the oil, the sealing structure must be disassembled before oil can be filled again. The repeated sealing, unsealing, and venting operations are cumbersome, especially when changing oil in a large number of pieces of equipment, which consumes time and manpower, resulting in low oil changing efficiency. In some cases, poor sealing can even cause air pressure leakage and poor oil drainage, further affecting the work progress.

[0021] Therefore, this utility model proposes an oil receiving hopper, referring to... Figure 1 and Figure 2 It includes a funnel 100, a thrust head 200, a retaining ring 300, a first adapter 400, and a second adapter 500. The first adapter 400 has a first channel, and its bottom has a connecting part 410 for sealing connection with the oil inlet of a measuring cup. The second adapter 500 is coaxially disposed on the top of the first adapter 400 and threadedly connected to it. The funnel 100 is fixedly disposed on the top of the second adapter 500, and the second adapter 500 has a connection part for sealing connection with the funnel. A second channel is connected to the internal space of the funnel 100. The lower end of the second channel is coaxially connected to the upper end of the first channel. The retaining ring 300 is disposed in the second channel near the end of the funnel 100. The retaining ring 300 is threadedly connected to the second adapter 500. The thrust head 200 is movably disposed in the second channel and located below the retaining ring 300. The thrust head 200 has a sealing surface 210 facing the retaining ring 300, and the sealing surface 210 is used to abut against the lower end face of the retaining ring 300. Specifically, the first adapter 400 has a first threaded hole at its top, and the second adapter 500 has a second external thread at its bottom. The first threaded hole and the second external thread are threadedly connected. The second adapter 500 has a second threaded hole at its top, and the retaining ring 300 has a first external thread on its outer wall. The second threaded hole and the first external thread are threadedly connected. Specifically, the first adapter 400 has a first threaded hole at its top, the second adapter 500 has a second external thread at its bottom, the first threaded hole and the second external thread are threadedly connected, the second adapter 500 has a second threaded hole at its top, the retaining ring 300 has a first external thread on its outer wall, and the second threaded hole and the first external thread are threadedly connected.

[0022] The funnel 100 provides initial guidance and converges the liquid into the subsequent channel; the second adapter 500 connects the funnel 100 and the first adapter 400 to ensure smooth flow of lubricating oil; the first adapter 400 connects the measuring cup and the second adapter 500 to provide a transmission channel for lubricating oil; the retaining ring 300 is located in the second channel near the end of the funnel 100 and is threadedly connected to the second adapter 500 to provide a mating surface for the thrust head 200; the thrust head 200 moves axially in the second channel, changing its position according to the air pressure in the measuring cup, and its sealing surface 210 can abut against the retaining ring 300 to block the second channel. With the cooperation of the thrust head 200 and the retaining ring 300, under pressure, the air pressure pushes the thrust head 200 to block the second channel, achieving airtight sealing of the measuring cup. When the measuring cup is depressurized, the thrust head 200 moves downward under gravity, disengaging from the retaining ring 300, allowing the liquid to flow smoothly through the funnel 100 through the second and first channels, and finally into the measuring cup. This makes it easy to install and use, eliminates cumbersome sealing and unsealing steps, shortens the oil change time for a single unit, reduces errors from traditional manual sealing, lowers the risk of air pressure leakage, and ensures smooth oil drainage.

[0023] In actual use, the oil is poured in through the inlet of the funnel 100. Under normal pouring conditions and with the measuring cup unpressurized, the thrust head 200 is positioned relatively low in the second channel due to its own gravity. The oil can flow into the measuring cup through the funnel 100, the second channel, and the first channel by gravity. When the measuring cup is pressurized, as the air pressure inside the measuring cup increases, the upward thrust generated by the air pressure acts on the thrust head 200, causing it to overcome its own gravity and move upward along the second channel until the sealing surface 210 of the thrust head 200 tightly abuts against the lower end face of the retaining ring 300. The fit between the two seals the second channel, achieving an airtight effect, preventing gas exchange, and ensuring the airtightness of the measuring cup.

[0024] Under the influence of gravity, the thrust head 200 may move excessively downwards, potentially even dislodging from its normal working channel, thus affecting the normal oil injection process. Therefore, in one embodiment, a washer 600 is included. The washer 600 is disposed between the first adapter 400 and the second adapter 500. The inner diameter of the washer 600 is smaller than the maximum outer diameter of the thrust head 200, used to limit the lower limit of the thrust head 200's downward movement. The washer 600 can limit the lower limit of the thrust head 200's downward movement, ensuring that the thrust head 200 always remains within a reasonable range of motion. This guarantees that it can normally disengage from the retaining ring 300 to allow oil to flow smoothly under no-pressure conditions, while preventing excessive downward movement that could lead to situations such as dislodging from the second channel or unnecessary collisions with other components. This helps maintain the overall structural and functional stability of the oil receiving hopper.

[0025] There are tiny gaps at the threaded connection surfaces of the first adapter 400 and the second adapter 500, which could allow internal gas and liquid to leak out. Therefore, in one embodiment, a first sealing ring 700 is also included. The bottom surface of the second adapter 500 has a first groove 510, and the first sealing ring 700 is disposed within the first groove 510. When the first adapter 400 and the second adapter 500 are threadedly connected, the first sealing ring 700 is compressed and sealed between the upper end face of the first adapter 400 and the lower end face of the second adapter 500. The compression of the first sealing ring 700 between the first adapter 400 and the second adapter 500 effectively fills the tiny gaps created by the threaded connection, preventing liquid or gas leakage from this area. Especially when the measuring cup is pressurized, it ensures stable internal air pressure and avoids airtightness failure due to leakage. By eliminating the leakage hazard at the connection 410, it reduces problems such as component corrosion and contamination caused by leakage, indirectly extending the service life of the oil receiving cup and reducing maintenance costs.

[0026] Since the metal contact surfaces of the thrust head 200 and the retaining ring 300 are difficult to fit completely, there will inevitably be tiny gaps. When the measuring cup is pressurized, gas may leak from these gaps. Therefore, in one embodiment, a second sealing ring 710 is also included. The sealing surface 210 of the thrust head 200 is provided with a second groove 220, and the second sealing ring 710 is disposed in the second groove 220. When the sealing surface 210 of the thrust head 200 abuts against the lower end surface of the retaining ring 300, the second sealing ring 710 is compressed and sealed between the sealing surface 210 of the thrust head 200 and the lower end surface of the retaining ring 300. The second sealing ring 710 is compressed between the thrust head 200 and the retaining ring 300, which can fill the tiny gap between the contact surfaces of the two, ensure a tight seal, effectively prevent gas from leaking from the second channel, and ensure the airtightness of the measuring cup when it is pressurized. Through the buffering compensation effect of the sealing ring, the processing requirements such as flatness and smoothness of the sealing surface 210 of the thrust head 200 and the lower end surface of the retaining ring 300 can be appropriately reduced, thereby reducing manufacturing costs while ensuring the sealing effect.

[0027] Long-term exposure of the funnel 100 inlet can lead to the accumulation of dust and impurities in the internal channel. When oil is injected, these contaminants can enter the measuring cup along with the oil, contaminating it. Therefore, in one embodiment, a dust cover 800 and a hinge shaft 810 are also included. One end of the dust cover 800 is hinged to the funnel 100 via the hinge shaft 810. The dust cover 800 can rotate around the hinge shaft 810 to cover or open the inlet of the funnel 100. When the oil receiving funnel is not in use, the dust cover 800 can cover the inlet of the funnel 100, effectively preventing dust, impurities, insects, and other foreign objects from entering the funnel 100 and its internal channel, ensuring the cleanliness of the oil flow path and preventing contaminants from contaminating the oil and affecting its quality. The flipping structure achieved by the hinge shaft 810 makes the opening and closing of the dust cover 800 simple and effortless, requiring no additional disassembly or storage. It can be quickly opened when in use and promptly closed when not in use, adapting to the needs of frequent use scenarios.

[0028] The dust cover 800, relying solely on gravity, may accidentally open due to slight impacts, vibrations, or tilting, allowing dust and impurities to enter the funnel 100 and disrupt its internal cleanliness. Therefore, in one embodiment, the inlet edge of the funnel 100 is provided with an arc-shaped protrusion 820, and the dust cover 800, near the funnel 100, has a fastening part 830 that engages with the arc-shaped protrusion 820. When the dust cover 800 covers the inlet of the funnel 100, the fastening part 830 engages with the arc-shaped protrusion 820. The engagement of the fastening part 830 and the arc-shaped protrusion 820 forms a mechanical lock, ensuring that it always tightly covers the inlet of the funnel 100, continuously providing dust and dirt protection. Even in environments with vibration or tilting, the fastening structure maintains the closed state of the dust cover 800, expanding the applicable environment range of the oil receiving funnel.

[0029] After the thrust head 200 moves upward, it may not be able to completely cover the inner hole, forming an annular gap at the edge through which gas can leak. Therefore, in one embodiment, the inner diameter of the retaining ring 300 is smaller than the maximum diameter of the sealing surface 210 of the thrust head 200. This smaller diameter ensures that after the thrust head 200 moves upward, the sealing surface 210 can completely cover the inner hole of the retaining ring 300, forming a comprehensive sealing coverage area and preventing leakage channels caused by incomplete coverage. This dimensional difference still provides a certain sealing redundancy, ensuring the effective contact area between the sealing surface 210 and the retaining ring 300, and maintaining basic sealing performance.

[0030] When the thrust head 200 moves within the second channel, it may experience eccentricity or offset, causing its sealing surface 210 to not accurately align with the lower end face of the retaining ring 300. Therefore, in one embodiment, the top of the thrust head 200 is provided with a guide portion 230, the outer diameter of which gradually decreases from bottom to top. The retaining ring 300 has a guide hole 310 at its center that mates with the guide portion 230. The gradually decreasing outer diameter of the guide portion 230, in conjunction with the guide hole 310 of the retaining ring 300, provides a precise guide path for the up-and-down movement of the thrust head 200, ensuring it always moves axially and avoiding lateral offset or eccentricity. The interaction between the guide portion 230 and the guide hole 310 reduces the possibility of unnecessary friction or collision between the thrust head 200 and other components during movement, allowing it to slide smoothly within the channel, effectively preventing jamming and improving operational smoothness and stability.

[0031] After prolonged use, the retaining ring 300 may become difficult to disassemble and assemble due to oil stains and micro-rust on the threads. Therefore, in one embodiment, the guide hole 310 is a box-shaped hole, which is used to mate with a box-shaped wrench. The multi-contact design of the box-shaped hole can effectively prevent the wrench from slipping, reducing the risk of component damage or operator hand injuries caused by slippage; while meeting the tool mating requirements, the central channel of the box-shaped hole can still effectively mate with the guide portion 230 of the thrust head 200, without affecting the axial movement accuracy of the thrust head 200, achieving dual use of one hole and simplifying the overall structure of the retaining ring 300.

[0032] Users may need to equip corresponding oil receiving hoppers for different sizes of measuring cups, leading to increased equipment procurement costs. Therefore, in one embodiment, the connecting part 410 is provided with a third external thread 420. The third external thread 420 can connect with the internal threads of different sizes of measuring cups, allowing one oil receiving hopper to be compatible with multiple measuring cups, reducing the number of special accessories and lowering the user's equipment investment costs; the thread engagement allows for quick connection with different measuring cups, improving the efficiency of oil changing and measuring operations, and is especially suitable for scenarios that require frequent measuring cup changes.

[0033] Preferably, a third sealing ring 440 is also included. The bottom surface of the connecting portion 410 is provided with a third groove 430, and the third sealing ring 440 is disposed within the third groove 430. When the connecting portion 410 is assembled and abuts against the measuring cup, the third sealing ring 440 is compressed and sealed between the connecting portion 410 and the top surface of the measuring cup. The compression of the third sealing ring 440 between the connecting portion 410 and the top surface of the measuring cup fills the tiny gaps at the contact surfaces and the leakage channels of the threaded connection. Regardless of whether the measuring cup is under normal pressure or pressurization, it effectively prevents liquid leakage or gas leakage, improving the overall sealing reliability.
