Description

Technical Field

[0001] This utility model relates to the field of gasoline quality testing technology, and in particular to a gearbox oil receiving fixture. Background Technology

[0002] In the field of automotive manufacturing and quality inspection, the testing and evaluation of transmission fluid levels is a crucial step in ensuring the stability and reliability of the transmission system. According to evaluation standards such as the Vehicle Inspection Method, precise weighing and measurement are required before and after fluid filling and draining to obtain accurate data on fluid consumption or residue. However, in traditional operations, this generally relies on manual removal of the drain plug using tools and manual collection of fluid. This traditional method suffers from low efficiency, poor measurement accuracy, and high safety risks, severely hindering the development of inspection processes and failing to meet the demands of modern intelligent manufacturing for efficient, precise, and safe operations. Utility Model Content

[0003] The main purpose of this utility model is to propose a gearbox oil connection fixture, which aims to solve the problems of how to improve work efficiency, measurement accuracy and operational safety.

[0004] To achieve the above objectives, this utility model proposes a gearbox oil connection fixture, which includes:

[0005] An oil reservoir has an upward-facing cavity for collecting oil discharged from the transmission; the orthographic projection of the opening onto a plane perpendicular to a first direction completely covers the oil drain port of the transmission, and the opening is oriented toward the oil drain port.

[0006] The disassembly mechanism includes a connector and a bolt drive head. Both the bolt drive head and the oil reservoir are connected to the connector. The bolt drive head is located above the opening and is used to engage with the drain bolt.

[0007] A grip mechanism is provided, which is connected to the outer wall of the oil reservoir. The grip mechanism can drive the bolt drive head to rotate through the oil reservoir and the connector, so that the bolt drive head drives the drain bolt to rotate relative to the gearbox.

[0008] In one embodiment, the gearbox oil receiving fixture further includes a reinforcing frame, the reinforcing frame including a fixing frame located inside the cavity, and the connecting member and the cavity wall of the cavity being connected to the fixing frame.

[0009] In one embodiment, the fixing frame includes a plurality of radial reinforcing members, which are arranged at intervals along the circumference of the connector. The two ends of each radial reinforcing member are respectively connected to the connector and the cavity wall of the cavity. The plurality of radial reinforcing members include a first radial reinforcing member, a second radial reinforcing member, a third radial reinforcing member, and a fourth radial reinforcing member. The first radial reinforcing member and the third radial reinforcing member are respectively located on two sides of the connector that are opposite to each other along a second direction. The second radial reinforcing member and the fourth radial reinforcing member are respectively located on two sides of the connector that are opposite to each other along a third direction. The first direction, the second direction, and the third direction are perpendicular to each other.

[0010] In one embodiment, the fixing frame further includes a plurality of circumferential reinforcing members, which are arranged radially spaced along the connector. Each circumferential reinforcing member includes a plurality of reinforcing plates, which are arranged circumferentially spaced along the connector. Each reinforcing plate is located between two adjacent radial reinforcing members and is connected to two adjacent radial reinforcing members.

[0011] The plurality of circumferential reinforcing members include a first circumferential reinforcing member, a second circumferential reinforcing member, and a third circumferential reinforcing member. The first circumferential reinforcing member, the second circumferential reinforcing member, and the third circumferential reinforcing member are arranged at intervals in a direction away from the connecting member. The reinforcing plate of the first circumferential reinforcing member is connected to the outer wall of the connecting member on the side away from the second circumferential reinforcing member. The reinforcing plate of the third circumferential reinforcing member is connected to the cavity wall of the cavity on the side away from the second circumferential reinforcing member.

[0012] In one embodiment, the oil can includes a body and an annular flange extending upward from the top edge of the body. The body and the annular flange together enclose the cavity, and the upper edge of the annular flange forms the opening. Multiple fixing brackets are included, including a first fixing bracket and a second fixing bracket. Both the first and second fixing brackets are connected to the body. The first and second fixing brackets are arranged sequentially along the first direction away from the annular flange. The side of the first fixing bracket away from the second fixing bracket is a bearing surface capable of supporting the drain bolt. The bearing surface is lower than the upper edge of the annular flange, which restricts the horizontal displacement of the drain bolt. The connector and the handle mechanism are both connected to the body.

[0013] In one embodiment, the kettle body includes an annular sidewall and a bottom plate, the bottom plate being connected to the annular sidewall, the top edge of the annular sidewall extending upward to form the annular flange, the bottom plate, the annular sidewall, and the annular flange together forming the cavity, the connector and the handle mechanism being respectively connected to the two sides of the bottom plate that are opposite to each other along the first direction, and the end of the connector away from the bottom plate extending out of the opening and connecting to the bolt drive head.

[0014] In one embodiment, the annular sidewall extends along the first direction and gradually widens in a direction away from the base plate; the annular flange is formed by the top edge of the annular sidewall continuing to extend along the widening direction.

[0015] And / or,

[0016] A flow guide nozzle communicating with the cavity is provided on the annular flange.

[0017] In one embodiment, the connector is detachably connected to the bolt drive head.

[0018] In one embodiment, the connector includes a connecting rod and a boss. Both the boss and the oil reservoir are connected to the connecting rod. The bolt drive head is provided with a groove and a protrusion. The boss engages with the groove to restrict the rotation of the connecting rod relative to the bolt drive head. The protrusion engages with a recess on the drain bolt to restrict the rotation of the drain bolt relative to the bolt drive head.

[0019] In one embodiment, the outer wall of the oil container is provided with a handle, and the number of handles is multiple, with the multiple handles arranged at intervals along the circumference of the oil container;

[0020] And / or,

[0021] The handle mechanism includes a connecting frame and a gripping member. The connecting frame is provided with a mounting cavity. The gripping member is located in the mounting cavity. The gripping member includes a first gripping rod and a second gripping rod connected to each other. The first gripping rod and the second gripping rod are arranged vertically. Both the first gripping rod and the second gripping rod are connected to the cavity wall of the mounting cavity. The connecting frame is connected to the bottom of the oil can.

[0022] And / or,

[0023] The oil can is a one-piece molded part, and the disassembly mechanism and the handle mechanism are both fixedly connected to the oil can.

[0024] In this embodiment of the invention, the gearbox oil receiving fixture includes an oil reservoir, a disassembly mechanism, and a handle mechanism. The oil reservoir has an upward-facing cavity, and the orthographic projection of the opening onto a plane perpendicular to the first direction completely covers the gearbox's drain port. The opening is oriented towards the drain port, ensuring that the oil flow path is perfectly aligned with the cavity, achieving complete oil reception. This effectively avoids the problems of spraying, splashing, or dripping caused by manual oil collection in traditional operations, ensuring the accuracy of oil weighing and meeting the measurement accuracy requirements of evaluation standards such as vehicle inspection methods. The disassembly mechanism includes a connector and a bolt drive head. Both the bolt drive head and the oil reservoir are connected to the connector. The bolt drive head is located above the opening and is used to engage with the drain bolt to transmit torque. This integrated design replaces traditional tools with only a single disassembly function, allowing drain bolt disassembly and oil collection to be completed in the same operation, significantly improving work efficiency. The single-unit operation time is significantly reduced from the original 600 seconds to approximately 60 seconds, effectively handling the inspection tasks of over a hundred units per month and significantly reducing cumulative working hours. The handle mechanism connects to the outer wall of the oil reservoir, enabling the bolt drive head and drain bolt to rotate relative to the gearbox via the oil reservoir and connector. The operator only needs to hold the handle mechanism to complete all actions, eliminating the need for close contact with the high-temperature oil or additional tool changes. This fundamentally isolates the risk of burns from hot oil splashes or container tipping during operation, improving operational safety. The method of using this fixture is as follows: First, use a special tool (such as a torque wrench) to pre-loosen the drain bolt to a certain extent to overcome its initial pre-tightening force. Then, align the bolt drive head of this fixture with the loosened drain bolt and secure it. The operator holds the handle mechanism and applies rotational force, causing the bolt drive head to continue loosening and finally removing the drain bolt via the oil reservoir and connector. Simultaneously, the oil flowing from the drain port falls directly into the lower cavity for collection. Finally, weigh the fixture after collecting the oil and, combined with the fixture's preset empty weight or initial weight, calculate the net weight of the collected oil. This oil volume data is used for subsequent measurement analysis and quality evaluation. This utility model integrates the oil can, disassembly mechanism, and handle mechanism into a single unit, enabling simultaneous disassembly of the drain bolt and collection of oil. This not only improves work efficiency but also effectively prevents oil leakage and environmental pollution through precise spatial alignment and gravity guidance, ensuring a clean, safe, and accurate oil collection process. Furthermore, the overall structure is reliably linked and easy to operate, enhancing the tool's versatility and practicality. It is suitable for rapid disassembly and assembly operations on various vehicle models, achieving safe, convenient, and efficient use of the fixture. This truly solves the pain points of low efficiency, large errors, and high risks inherent in traditional operations. Attached Figure Description

[0039] In the field of automotive manufacturing and quality inspection, the testing and evaluation of transmission fluid levels is a crucial step in ensuring the stability and reliability of the transmission system. According to evaluation standards such as the Vehicle Inspection Method, precise weighing and measurement are required before and after fluid filling and draining to obtain accurate data on fluid consumption or residue. However, in traditional operations, this generally relies on manual removal of the drain plug using tools and manual collection of fluid. This traditional method suffers from low efficiency, poor measurement accuracy, and high safety risks, severely hindering the development of inspection processes and failing to meet the demands of modern intelligent manufacturing for efficient, precise, and safe operations.

[0040] After careful examination, the applicant discovered the following issues: First, the current tools are merely single-function bolt drive heads, lacking oil-receiving capabilities. This necessitates manual handling of containers or direct pouring of oil during operations, easily leading to oil spraying, splashing, or dripping. This not only pollutes the work environment but also directly causes oil loss, affecting the accuracy of weighing results and ultimately reducing the reliability of test evaluation data. Second, due to the lack of dedicated auxiliary structures, the entire disassembly process relies entirely on manual force, making it time-consuming and labor-intensive. A single disassembly can take up to 600 seconds, resulting in a massive accumulated workload and extremely low overall efficiency for the monthly testing of 106 units. Furthermore, the gearbox maintains a high temperature even after operation, with its internal oil reaching high temperatures. The existing tools cannot effectively isolate the operator from the hot oil, posing a serious risk of burns to workers during bolt removal and oil collection due to indirect contact with the hot oil.

[0041] The main purpose of this utility model is to propose a gearbox oil connection fixture to solve the problems of how to improve work efficiency, measurement accuracy and operational safety.

[0042] Please see Figure 1 , Figure 3 , Figure 5 and Figure 6 In one embodiment of this utility model, the gearbox oil receiving fixture 100 includes an oil reservoir 1, a disassembly mechanism 2, and a handle mechanism 3. The oil reservoir 1 is provided with a cavity 13 with an opening 121 facing upwards. The cavity 13 is used to collect the oil discharged from the gearbox. The orthographic projection of the opening 121 on a plane perpendicular to the first direction completely covers the oil drain port of the gearbox, and the opening 121 is oriented towards the oil drain port. The disassembly mechanism 2 includes a connector 21 and a bolt drive head 22. The bolt drive head 22 and the oil reservoir 1 are both connected to the connector 21. The bolt drive head 22 is located above the opening 121 and is used to engage with the drain bolt. The handle mechanism 3 is connected to the outer wall of the oil reservoir 1. The handle mechanism 3 can drive the bolt drive head 22 to rotate through the oil reservoir 1 and the connector 21, so that the bolt drive head 22 drives the drain bolt to rotate relative to the gearbox.

[0043] In the embodiments of this utility model, such as Figure 3As shown, the first direction is the vertical direction. The gearbox oil receiving fixture 100 includes an oil reservoir 1, a disassembly mechanism 2, and a handle mechanism 3. The oil reservoir 1 is provided with a cavity 13 with an opening 121 facing upwards. The orthographic projection of the opening 121 on a plane perpendicular to the first direction completely covers the oil drain port of the gearbox, and the opening 121 is oriented towards the oil drain port, thereby ensuring that the oil flow path is completely aligned with the cavity 13, achieving complete oil reception. This effectively avoids the problems of spraying, splashing, or dripping caused by manual oil receiving in traditional operations, ensuring the accuracy of oil weighing and meeting the measurement accuracy requirements of evaluation standards such as vehicle inspection methods. The disassembly mechanism 2 includes a connector 21 and a bolt drive head 22. Both the bolt drive head 22 and the oil reservoir 1 are connected to the connector 21. The bolt drive head 22 is located above the opening 121 and is used to engage with the drain bolt to transmit torque. This integrated linkage design replaces the traditional tool with only a single disassembly function, allowing the disassembly of the drain bolt and the collection of oil to be completed in the same operation, greatly improving work efficiency. The operation time of a single unit is significantly reduced from the original 600 seconds to about 60 seconds, effectively handling the inspection task of more than 100 units per month and significantly reducing the cumulative working hours. The handle mechanism 3 is connected to the outer wall of the oil reservoir 1 and can drive the bolt drive head 22 and the drain bolt to rotate relative to the gearbox through the oil reservoir 1 and the connector 21. The operator only needs to hold the handle mechanism 3 to complete all actions without close contact with high-temperature oil or additional tool changes, fundamentally isolating the risk of burns caused by hot oil splashes or container tipping during operation and improving operational safety. The method of using this fixture is as follows: First, use a special tool (such as a torque wrench) to loosen the drain bolt to a certain extent in order to overcome its initial preload; then, align the bolt drive head 22 of this fixture with the loosened drain bolt and clamp it in place. The operator holds the handle mechanism 3 and applies rotational force, which drives the bolt drive head 22 to continue to loosen and finally remove the drain bolt through the oil can 1 and the connecting piece 21. At the same time, the oil flowing out of the drain port falls directly into the lower cavity 13 for collection; finally, weigh the fixture after collecting the oil and calculate the net weight of the collected oil by combining the preset empty weight or initial weight of the fixture. This oil volume data is used for subsequent measurement analysis and quality evaluation.

[0044] The technical solution of this utility model integrates the oil can 1, the disassembly mechanism 2, and the handle mechanism 3 into one unit, realizing the simultaneous operation of oil drain bolt disassembly and oil collection. This not only improves work efficiency, but also effectively prevents oil leakage and environmental pollution by relying on precise spatial alignment and gravity guidance, ensuring that the oil collection process is clean, safe, and accurate. At the same time, the overall structure is reliable and easy to operate, improving the versatility and practicality of the tool. It is suitable for rapid disassembly and assembly operations of various vehicle models, realizing safe, convenient, and efficient use of the fixture, and truly solving the pain points of low efficiency, large errors, and high risks in traditional operations.

[0045] Please see Figure 2 and Figure 3 In one embodiment, the gearbox oil receiving fixture 100 further includes a reinforcing frame 4, which includes a fixing frame located within the cavity 13. Both the connecting member 21 and the cavity wall of the cavity 13 are connected to the fixing frame. Specifically, by setting the fixing frame inside the cavity 13 and simultaneously fixing it to both the connecting member 21 and the cavity wall of the cavity 13, a stable force transmission path is formed. This allows the torque generated during disassembly to be effectively transmitted from the connecting member 21 to the oil reservoir 1 via the fixing frame, avoiding stress concentration at local connection points and significantly improving the rigidity and load-bearing capacity of the overall structure. This design not only enhances the structural strength of the oil reservoir 1 at stress-bearing locations, preventing deformation or cracking due to repeated stress, but also ensures smooth and reliable disassembly operations, improving operational stability and safety. Simultaneously, this structure allows the oil reservoir 1 to adopt a lightweight design while maintaining strength, balancing practicality and manufacturing economy, further extending the fixture's service life, and making it suitable for high-frequency, high-intensity testing environments.

[0046] Please see Figure 3 and Figure 4 In one embodiment, the fixing frame includes a plurality of radial reinforcing members, which are arranged at intervals along the circumference of the connecting member 21. The two ends of each radial reinforcing member are respectively connected to the connecting member 21 and the cavity wall of the cavity 13. The plurality of radial reinforcing members include a first radial reinforcing member 4111, a second radial reinforcing member 4112, a third radial reinforcing member 4113, and a fourth radial reinforcing member 4114. The first radial reinforcing member 4111 and the third radial reinforcing member 4113 are respectively located on opposite sides of the connecting member 21 along a second direction, and the second radial reinforcing member 4112 and the fourth radial reinforcing member 4114 are respectively located on opposite sides of the connecting member 21 along a third direction. The first direction, the second direction, and the third direction are perpendicular to each other. Specifically, as shown... Figure 3 As shown, the second direction is the left-right direction, and the third direction is the front-back direction. By setting a cross-shaped symmetrical radial reinforcement structure, the torque borne by the connector 21 when rotating to disassemble the drain bolt can be evenly transmitted to the cavity wall of the oil reservoir 1 through the reinforcements in the four directions, achieving multi-directional support and load distribution, effectively avoiding structural deformation, loosening of connections, or local cracking caused by unilateral force or uneven loading. This design significantly improves the torsional stiffness of the connection and the overall structural stability, ensuring a smooth and reliable disassembly process, preventing the bolt drive head 22 from disengaging from the drain bolt, and improving force transmission efficiency and operational feel. In addition, the symmetrically arranged radial reinforcements are beneficial for mold forming and mass production, balancing structural strength and manufacturing economy, and are suitable for high-intensity, high-frequency gearbox testing operations, further improving the durability and practicality of the fixture.

[0047] Please see Figure 3 and Figure 4In one embodiment, the fixing frame further includes a plurality of circumferential reinforcing members, which are arranged radially spaced along the connector 21. Each circumferential reinforcing member includes a plurality of reinforcing plates 41151, which are arranged circumferentially spaced along the connector 21. Each reinforcing plate 41151 is located between two adjacent radial reinforcing members and is connected to two adjacent radial reinforcing members. The plurality of circumferential reinforcing members include a first circumferential reinforcing member 4115, a second circumferential reinforcing member 4116, and a third circumferential reinforcing member 4117. The first circumferential reinforcing member 4115, the second circumferential reinforcing member 4116, and the third circumferential reinforcing member 4117 are arranged spaced apart in a direction away from the connector 21. The reinforcing plate 41151 of the first circumferential reinforcing member 4115 is located away from the second circumferential reinforcing member 4116. One side of the first circumferential reinforcement 4117 is connected to the outer wall of the connector 21, and the side of the reinforcing plate 41151 of the third circumferential reinforcement 4117 away from the second circumferential reinforcement 4116 is connected to the cavity wall of the cavity 13. Specifically, multiple circumferential reinforcements and multiple radial reinforcements form a grid-like support structure. Among them, the side of all the reinforcing plates 41151 of the first circumferential reinforcement 4115 away from the second circumferential reinforcement 4116 is connected to the outer wall of the connector 21 to enhance the circumferential fixing strength of the connector 21. The side of all the reinforcing plates 41151 of the third circumferential reinforcement 4117 away from the second circumferential reinforcement 4116 is connected to the cavity wall of the cavity 13 to achieve a firm connection between the fixing frame and the cavity wall of the oil can 1. The second circumferential reinforcement 4116 is located in the middle position to further improve the stability of the middle section of the radial reinforcement. This composite reinforcement structure not only enables efficient torque transfer from connector 21 to the cavity wall via multiple paths, significantly improving the overall torsional stiffness and load-bearing capacity, but also effectively suppresses lateral buckling or deformation of the radial reinforcement during stress, preventing structural failure due to localized stress concentration. This design greatly enhances the overall stability and durability of the fixture, ensuring reliable connection and smooth operation during disassembly. It is particularly suitable for high-frequency, high-torque gearbox testing scenarios, while also considering lightweight construction and manufacturing feasibility, further improving the practicality and reliability of the fixture.

[0048] It should be noted that the number of radial and circumferential reinforcing members is not strictly limited and can be flexibly set according to the actual structural strength requirements, load size, and manufacturing process. Multiple radial reinforcing members can be arranged at intervals along the circumference of the connector 21 to uniformly transfer the torque borne by the connector 21 to the cavity wall of the cavity 13, improving the overall torsional stiffness. Multiple circumferential reinforcing members can also be arranged at intervals along the circumference, intersecting and connecting with each radial reinforcing member to form a grid-like support structure, further enhancing the overall stability of the fixing frame. In this embodiment, four radial reinforcing members are preferably arranged in a cross-shaped symmetrical distribution on both sides of the connector 21; three circumferential reinforcing members are preferably arranged sequentially in a direction away from the connector 21 to achieve multi-level force transmission and structural reinforcement. However, it should be understood that the number of radial reinforcing members can be three, four, five, or more, and the number of circumferential reinforcing members can also be set to three or more as needed, as long as the structural connection and force transmission requirements between the connector 21 and the cavity wall are met, they all fall within the protection scope of this utility model.

[0049] Please see Figure 3In one embodiment, the oil pot 1 includes a pot body 11 and an annular flange 12 extending upward from the top edge of the pot body 11. The pot body 11 and the annular flange 12 together enclose a cavity 13, and the upper edge of the annular flange 12 forms an opening 121. Multiple fixing brackets are provided, including a first fixing bracket 411 and a second fixing bracket 412. Both the first fixing bracket 411 and the second fixing bracket 412 are connected to the pot body 11. The first fixing bracket 411 and the second fixing bracket 412 are arranged sequentially along a first direction away from the annular flange 12. The side of the first fixing bracket 411 away from the second fixing bracket 412... The bearing surface 4118 is designed to support the drain bolt. The bearing surface 4118 is lower than the upper edge of the annular flange 12, which restricts the horizontal displacement of the drain bolt. Both the connector 21 and the handle mechanism 3 are connected to the vessel body 11. Specifically, the bearing surface 4118 on the first fixing bracket 411 is lower than the upper edge of the annular flange 12, allowing the drain bolt to be stably supported within the cavity 13 after disassembly, preventing it from falling or being lost. Simultaneously, the annular flange 12 surrounds the drain bolt horizontally, restricting its lateral displacement and preventing displacement or slippage due to vibration or tilting. Both the connector 21 and the handle mechanism 3 are connected to the vessel body 11. Rotating the connector 21 via the handle mechanism 3 completes the disassembly of the drain bolt and the collection of waste oil. Through this design, the fixing bracket not only enhances the structural strength of the oil vessel 1 and transmits torque but also supports the disassembled bolt, achieving integrated operation of bolt removal, oil collection, and drain bolt storage. This structure effectively avoids the safety hazards of manually handling high-temperature bolts in traditional operations, improves the convenience and safety of operation, and facilitates subsequent cleaning and management. It is particularly suitable for high-frequency, high-safety-requirement transmission oil level testing scenarios, significantly improving overall operational efficiency and standardization.

[0050] Please see Figure 3In one embodiment, the kettle body 11 includes an annular sidewall 111 and a bottom plate 112. The bottom plate 112 is connected to the annular sidewall 111. The top edge of the annular sidewall 111 extends upward to form an annular flange 12. The bottom plate 112, the annular sidewall 111, and the annular flange 12 together enclose a cavity 13. The connector 21 and the grip mechanism 3 are respectively connected to the two sides of the bottom plate 112 that are opposite to each other along the first direction. The end of the connector 21 away from the bottom plate 112 extends out of the opening 121 and is connected to the bolt drive head 22. Specifically, the connector 21 and the grip mechanism 3 are respectively connected to the two sides of the bottom plate 112 that are opposite to each other along the first direction to form a structure with the bottom plate 112 as the connection base. This not only improves the stability of the overall assembly, but also makes the grip operation and torque output more balanced and reliable. The end of the connector 21 furthest from the base plate 112 extends upward and protrudes from the opening 121 of the cavity 13, connecting to the bolt drive head 22. This efficiently transmits the rotational force applied by the grip mechanism 3 through the oil reservoir 1 and the connector 21 to the bolt drive head 22, achieving stable disassembly of the drain bolt. This structural design highly integrates the disassembly mechanism 2 with the oil receiving structure, and the power transmission path is clear and the force distribution is uniform, effectively avoiding shaking or disengagement during operation. Simultaneously, the grip mechanism 3 is located on the outer wall of the base plate 112, without intruding into the cavity 13, improving safety and facilitating cleaning and maintenance. This structure, through a reasonable structural layout, achieves synergistic optimization of the fixture in terms of strength, stability, ease of operation, and functionality, making it suitable for high-frequency, high-precision gearbox oil level detection operations.

[0051] Please see Figure 3 In one embodiment, the annular sidewall 111 extends along a first direction and gradually widens in a direction away from the base plate 112; the annular flange 12 extends from the top edge of the annular sidewall 111 along the widening direction; and / or, a guide nozzle 122 communicating with the cavity 13 is provided on the annular flange 12; specifically, the annular sidewall 111 forms a trumpet-shaped structure that is larger at the top and smaller at the bottom, which helps to expand the coverage of the opening 121 over the drain port, guides the oil and the removed drain bolts to fall smoothly into the cavity 13, and effectively prevents splashing, dripping or jamming. The annular flange 12 extends from the top edge of the annular sidewall 111 along the widening direction and smoothly transitions with the annular sidewall 111, forming a continuously widened inner wall profile, which not only enhances the overall integrity and aesthetics of the structure, but also avoids the problems of oil residue or bolt jamming caused by steps or narrowing, and improves the reliability and ease of cleaning of the fixture. In addition, the annular flange 12 is provided with a guide nozzle 122 that communicates with the cavity 13. This can be used to orderly discharge the oil after the oil collection is completed, reducing the risk of spillage caused by manual dumping. This further expands the functionality of the fixture in the entire process of oil collection, storage and transfer, and meets the requirements of vehicle inspection method and other evaluation standards for measurement accuracy and operation standardization.

[0052] Please see Figure 5 and Figure 6 In one embodiment, the connector 21 and the bolt drive head 22 are detachably connected. Specifically, this design allows the bolt drive head 22 to be flexibly replaced according to actual operational needs to adapt to different types or specifications of transmission drain plugs, significantly improving the versatility and applicability of the fixture. When the drive head becomes worn, deformed, or stuck due to long-term use, it can be directly removed from the connector 21 and replaced with a new part, without the need to replace the entire fixture, effectively reducing maintenance costs and resource waste. At the same time, the detachable connection method supports the use of standardized interfaces, facilitating compatibility with general manual or power tools, further enhancing the flexibility and convenience of operations. In addition, this structure facilitates the individual cleaning and maintenance of the drive head, preventing oil accumulation from affecting connection reliability. By achieving modular separation of the connector 21 and the bolt drive head 22, this embodiment not only meets the testing needs of multiple vehicle models and specifications but also promotes the development of fixtures towards standardization, maintainability, and low cost, making it particularly suitable for high-frequency, multi-variety transmission oil level testing scenarios.

[0053] Please see Figure 5 and Figure 6In one embodiment, the connector 21 includes a connecting rod 211 and a boss 212. Both the boss 212 and the oil reservoir 1 are connected to the connecting rod 211. The bolt drive head 22 is provided with a slot 221 and a protrusion 222. The boss 212 engages with the slot 221 to restrict the rotation of the connecting rod 211 relative to the bolt drive head 22. The protrusion 222 engages with the recess on the drain bolt to restrict the rotation of the drain bolt relative to the bolt drive head 22. Specifically, the boss 212 and the oil reservoir 1 are both connected to the connecting rod 211 to form a stable force transmission structure. The bolt drive head 22 is provided with a slot 221 and a protrusion 222. The protrusion 212 engages with the slot 221 to achieve a torsional connection between the connecting rod 211 and the bolt drive head 22, effectively limiting the relative rotation between the two during disassembly and ensuring that the rotational torque is efficiently and stably transmitted from the connecting rod 211 to the bolt drive head 22. The protrusion 222 engages with the recessed hole (such as an internal hexagonal hole or a special locking hole) on the head of the drain bolt to limit the relative rotation between the drain bolt and the bolt drive head 22, thereby achieving reliable driving of the bolt. This double-locking structure not only ensures the complete power transmission chain from the handle to the drain bolt, but also improves the stability of the connection and the safety of operation. At the same time, the locking design supports the quick installation and removal of the bolt drive head 22, making it easy to replace different models of drive heads according to the specifications of the drain bolt, thus improving the versatility and operational flexibility of the fixture. This compact structure and direct force transmission make it particularly suitable for high-frequency, high-reliability transmission fluid level detection scenarios, balancing functionality, maintainability, and ease of operation. In this embodiment, the bolt drive head 22 can utilize a hexagonal key sleeve from existing structures, which can engage with the recessed hole of the drain bolt for quick installation and reliable transmission.

[0054] According to one embodiment of the present invention, the connector 21 and the bolt drive head 22 can be detachably connected by means of threaded connection or snap-fit ​​connection.

The first gripping rod 321 and the second gripping rod 322 are arranged vertically, and both the first gripping rod 321 and the second gripping rod 322 are connected to the cavity wall of the mounting cavity 311. The connecting frame 31 is connected to the bottom of the oil container 1; and / or, the oil container 1 is a one-piece molded part, and the disassembly mechanism 2 and the grip mechanism 3 are both fixedly connected to the oil container 1; specifically, the multiple handles 5 are arranged at intervals along the circumference of the oil container 1, providing the operator with multiple angles and postures for gripping, which is especially suitable for working conditions where space is limited or where two hands are required to work together, significantly improving the flexibility and stability of operation. The connecting frame 31 of the grip mechanism 3 is connected to the bottom of the oil reservoir 1, allowing the gripping force to be evenly transmitted to the entire fixture through the bottom, avoiding uneven loading and improving stability and maneuverability during disassembly. The first gripping rod 321 and the second gripping rod 322 are vertically arranged to form a cross-shaped structure. This cross-shaped grip design is ergonomic, supports multi-directional force application, facilitates precise control of rotational movements, and prevents slippage or disengagement. The oil reservoir 1 is a one-piece molded component with good structural integrity and sealing performance, effectively preventing leakage during oil connection. Both the disassembly mechanism 2 and the grip mechanism 3 are fixedly connected to the oil reservoir 1, forming a highly integrated modular structure. This not only improves overall rigidity and reliability but also simplifies the assembly process, which is beneficial for mass production and quality control. Through the above design, this embodiment achieves synergistic optimization in terms of ease of operation, structural stability, manufacturing economy, and safety. It is particularly suitable for high-frequency, high-standard gearbox oil level detection operations, fully demonstrating the core innovative value of the fixture in terms of safety, convenience, and efficiency.
