Description

Technical Field

[0001] This utility model relates to the field of diesel engine repair and disassembly technology, and specifically to a diesel engine oil filter disassembly device. Background Technology

[0002] Diesel engine filters (oil filters) play a crucial role in the maintenance and upkeep of diesel engines. Their main function is to filter impurities and contaminants from diesel fuel, protecting engine components from damage. Regular replacement and removal of oil filters are essential for ensuring the normal operation of diesel engines. However, due to the varying sizes and structures of diesel engine filters, the removal process often presents challenges, especially when dealing with different models and brands of oil filters. The compatibility of removal tools and the efficiency of disassembly become pressing issues that need to be addressed.

[0003] Currently, there are several diesel engine oil filter removal tools available on the market. For example, patent CN210307553U discloses a special wrench for removing diesel engine filters, including a handle and a connected removal rod. This removal rod is designed to match the shape of the filter and can drive the filter through rotation to complete the removal operation. The advantages of this tool are that it avoids diesel fuel splashing inside the filter, requires less cleaning work during removal, and is relatively fast, making it suitable for standard diesel engine oil filters.

[0004] However, existing diesel engine oil filter removal tools have some defects and shortcomings, specifically in the following aspects:

[0005] Existing disassembly tools are typically designed for specific filter models, limiting their applicability. Diesel engine oil filters of different brands, models, and specifications may vary in size, shape, and installation method, making it difficult for existing disassembly tools to be universal. Therefore, for uncommon or special-specification diesel engine oil filters, existing tools are often ineffective, requiring users to purchase different sized disassembly tools, increasing costs and inconvenience.

[0006] While existing tools can effectively address the removal of some diesel engine oil filters, the procedures are cumbersome and inefficient in complex scenarios. This is especially true when dealing with oil filters that haven't been replaced for a long time or those deeply embedded in confined spaces; the removal process often takes considerable time and involves complex steps, increasing the difficulty and risk of error for manual operation. Furthermore, users of these tools need a certain level of technical knowledge and experience, and improper operation may damage the filter or other diesel engine components.

[0007] Current diesel engine oil filter removal tools often require complex designs to improve disassembly efficiency and compatibility, resulting in high production costs. Especially high-end custom tools, which are typically expensive and require precision components, undoubtedly increase the financial burden on users. For small repair shops or individual car owners, the excessively high cost prevents them from widely adopting these tools, reducing their market competitiveness.

[0008] Furthermore, since most existing disassembly tools rely on traditional mechanical rotational force for disassembly, improper operation may cause scratches or damage to the filter body, diesel engine oil pan, or other important components during the disassembly process. In addition, for filters that are stuck or adhered during disassembly, if the tool cannot effectively provide sufficient rotational or holding force, it may slip out, increasing the safety hazards during the disassembly process. Utility Model Content

[0009] The problem this invention aims to solve is that existing diesel engine oil filter removal tools suffer from poor compatibility, low removal efficiency, complex operation, high cost, and significant production difficulty, as well as the potential for damage to the filter or diesel engine components during disassembly. To address these issues, this invention provides a diesel engine oil filter removal device with enhanced compatibility. This device enables quick and easy disassembly of different types of oil filters, significantly improving disassembly efficiency, simplifying operation steps, reducing production costs, ensuring safety during disassembly, and preventing damage to the filter and other diesel engine components.

[0010] To address the aforementioned problems, this utility model provides a diesel engine oil filter removal device, including a handle component. The handle component has a detachable structure, and a manual rotating component is provided on the side end of the handle component. The manual rotating component is inserted along the side end of the handle component and threaded to the inner end. A locking component is sleeved on the manual rotating component at the joint of the side end of the handle component. The end of the manual rotating component away from the handle component is in surface contact with a chain-type adjustable locking component. The center of the chain-type adjustable locking component is wound around the diesel engine oil filter, and the extension end of the chain-type adjustable locking component is wound around the limiting groove of the handle component. By rotating the handle component, the chain-type adjustable locking component drives the diesel engine oil filter to rotate and be removed.

[0011] Preferably, the grip component includes a grip base, with an L-shaped limiting groove on the side end of the grip base that is identical to the upper end. A grip rod is fixedly mounted on the side end of the grip base, and a locking cover is provided at the end of the grip rod away from the grip base and is rotatably separated from it. The grip component has a detachable structure, making the disassembly device more flexible and convenient. The separate connection between the grip base and the grip rod can effectively ensure the fixation of the grip base and the grip rod, while facilitating installation and disassembly. The L-shaped limiting groove can effectively ensure the fixation of the extension end of the chain-type adjustable locking assembly.

[0012] Preferably, the outer edge of the handle rod side is provided with a threaded protrusion, and the inner edge of the locking cover is provided with a threaded positioning groove. The threaded protrusion and the threaded positioning groove are threadedly locked together. A threaded limiting cavity is opened at the center of the inner end of the locking cover. The threaded protrusion on the handle rod is threadedly locked together with the threaded positioning groove in the locking cover, which makes the fixing of the handle rod and the locking cover more secure and stable, avoiding loosening or slippage that may occur during disassembly, and improving the reliability and operational safety of the disassembly device.

[0013] Preferably, the manual rotating assembly includes a threaded screw, which passes sequentially through a clearance cavity at the center of the handle seat and the handle rod and extends forward to be threadedly fixed to the threaded limiting cavity groove of the locking cover. The threaded screw, through a precise threaded connection, provides a stable rotational torque and ensures a good fit between the manual rotating assembly and the handle component. The threaded limiting cavity groove in the locking cover initially limits and fixes the front end of the threaded screw, ensuring the overall stability of the device. A locking element fitted along the side joint of the manual rotating assembly with the handle component further locks and limits the center of the threaded screw, providing a double limiting and fixing function, thereby ensuring the overall stability of the threaded screw when the operator rotates the manual rotating assembly through the handle component.

[0014] Preferably, the other end of the threaded screw is fixedly connected to a sprocket, which is movably hinged to the inner end of the limiting support seat. The sprocket drives the chain-type adjustable locking assembly to efficiently rotate the motor filter. The transmission structure of the threaded screw and sprocket is more efficient and stable than traditional disassembly tools. The sprocket transmission structure makes the entire disassembly process smoother and reduces the wear of internal parts of the tool, thereby extending the service life of the device. In addition, the rotational torque provided during the disassembly process is more uniform, avoiding the risk of damage caused by excessive rotation.

[0015] Preferably, the limiting support seat has a U-shaped groove structure, and the extension end of the chain adjustable locking component limits the U-shaped groove of the support seat and contacts and connects with the sprocket surface. The structure of the U-shaped groove allows the chain to be firmly fixed on the support seat, preventing the chain from falling off or slipping during operation.

[0016] Preferably, the locking element is a locking nut.

[0017] Preferably, the chain-type adjustable locking assembly consists of multiple chains that are hinged to each other.

[0018] Compared with the prior art, the present invention achieves the following beneficial technical effects:

[0019] The disassembly device of this invention adopts an adjustable chain locking assembly, which can adapt to diesel engine oil filters of different specifications, shapes, and interfaces. The adjustable chain structure gives the device greater versatility and compatibility, avoiding the limitations of traditional tools that only support a single model, and reducing user costs.

[0020] This invention utilizes a rotating handle component to drive a chain-type adjustable locking assembly, enabling rapid and stable rotation and disassembly of the oil filter. Compared to existing tools, this device simplifies the operation steps, avoids cumbersome adjustment processes, and achieves a highly efficient and precise disassembly process. The disassembly time can be reduced to less than 5 seconds, thereby significantly improving work speed, greatly increasing disassembly efficiency, and reducing manual operation and maintenance time and costs.

[0021] This utility model features a simple and convenient structure, is easy to mass-produce, has low cost, and is intuitive to operate. Users do not need extensive technical knowledge to operate it easily, greatly reducing the risk of misoperation. Especially in confined or hard-to-reach spaces, the tool's flexibility and stability significantly reduce the possibility of operational errors, allowing users to easily complete disassembly work and improving operational safety and accuracy.

[0022] This invention combines a chain-type locking assembly with a rotary drive to ensure moderate force during disassembly, effectively avoiding damage to the oil filter and other diesel engine components caused by scratches or collisions during disassembly using traditional machinery. The precise control of the chain-type adjustable locking assembly makes the disassembly process gentler, avoiding jamming, slippage, or excessive force that may occur in traditional methods, thereby maximizing the safety and service life of the device.

Detailed Implementation

[0027] The present invention will be further explained below with reference to the accompanying drawings and embodiments.

[0028] Reference Figures 1 to 3 As shown, a diesel engine oil filter removal device includes a handle component 1, which is detachable. A manual rotating component 2 is provided on the side end of the handle component 1. The manual rotating component 2 passes through the side end of the handle component 1 and is threaded to the inner end. A locking component 3 is sleeved at the joint of the manual rotating component 2 along the side end of the handle component 1. The end of the manual rotating component 2 away from the handle component 1 is in surface contact with a chain-type adjustable locking component 4. The center of the chain-type adjustable locking component 4 is wound around the diesel engine oil filter 5. The extension end of the chain-type adjustable locking component 4 is wound around the limiting groove of the handle component 1. By rotating the handle component 1, the chain-type adjustable locking component 4 drives the diesel engine oil filter 5 to rotate and be removed.

[0029] The locking element 3 is a locking nut, and the chain-type adjustable locking assembly 4 consists of multiple chains that are hinged to each other.

[0030] The grip component 1 includes a grip base 101. The grip base 101 has an L-shaped limiting groove 102 on its side end, which is the same as the upper end. A grip rod 103 is fixedly provided on the side end of the grip base 101. A locking cover 104 is provided on the end of the grip rod 103 away from the grip base 101 and is rotatably separated from it. The grip component 1 has a detachable structure, which makes the disassembly device more flexible and convenient. The separation connection between the grip base 101 and the grip rod 103 can effectively ensure the fixation of the grip base 101 and the grip rod 103, and at the same time facilitates installation and disassembly. The L-shaped limiting groove 102 can effectively ensure the fixation of the extension end of the chain adjustable locking assembly 4.

[0031] The outer edge of the handle rod 103 is provided with a threaded protrusion 105, and the inner edge of the locking cover 104 is provided with a threaded positioning groove 106. The threaded protrusion 105 and the threaded positioning groove 106 are threadedly locked together. The center of the inner end of the locking cover 104 is provided with a threaded limiting cavity 107. The threaded protrusion 105 on the handle rod 103 and the threaded positioning groove 106 in the locking cover 104 are threadedly locked together, making the fixation of the handle rod and the locking cover more secure and stable, avoiding the loosening or slippage that may occur during disassembly, and improving the reliability and operational safety of the disassembly device.

[0032] The manual rotating assembly 2 includes a threaded screw 201. The threaded screw 201 passes sequentially through the clearance cavity opened at the center of the handle seat 101 and the handle rod 103 and extends forward to be threadedly fixed to the threaded limiting cavity 107 of the locking cover 104. The threaded screw 201, through a precise threaded connection, can provide a stable rotational torque and ensure a good fit between the manual rotating assembly 2 and the handle component 1. The threaded limiting cavity 107 in the locking cover 104 can initially limit and fix the front end of the threaded screw 201, ensuring the overall stability of the device. The locking member 3, which is sleeved at the side end of the manual rotating assembly 2 along the handle component 1, can lock and limit the center of the threaded screw 201 again, playing a double limiting and fixing role, thereby ensuring the overall stability of the threaded screw 201 when the operator rotates the manual rotating assembly 2 through the handle component 1.

[0033] The other end of the threaded screw 201 is fixedly connected to a sprocket 202, which is movably hinged to the inner end of the limiting support 203. The sprocket drives the chain-type adjustable locking assembly 4 to efficiently rotate the motor filter. The transmission structure of the threaded screw 201 and the sprocket 202 is more efficient and stable than traditional disassembly tools. The sprocket transmission structure makes the entire disassembly process smoother and reduces the wear of internal parts of the tool, thereby extending the service life of the device. In addition, the rotational torque provided during the disassembly process is more uniform, avoiding the risk of damage caused by excessive rotation.

[0034] The limiting support 203 has a U-shaped groove structure. The extension end of the chain adjustable locking component 4 limits the U-shaped groove of the supporting support 203 and is in contact with the sprocket 202. The U-shaped groove structure allows the chain to be firmly fixed on the support, preventing the chain from falling off or slipping during operation.

[0035] To facilitate understanding of the above technical solutions of this utility model, the following detailed description of the above technical solutions of this utility model is provided through specific usage methods.

[0036] The specific working process is as follows: First, the operator installs and disassembles the device, puts the threaded screw 201 of the manual rotating component 2 onto the locking part 3, and then passes it through the handle rod 103 of the handle component 1 and the relief cavity at the center of the handle seat 101 in sequence. The front end of the threaded screw 201 is threadedly fixed to the threaded limiting cavity groove 107 of the locking cover seat 104. Then, the other end of the handle rod 103 is rotated and fixedly connected to the locking cover seat 104 through the threaded protrusion 105 and the threaded positioning groove 106. Then, the locking part 3 is tightened in the opposite direction. Next, the operator adjusts the chain length of the locking end of the chain adjustable locking component 4 according to the specifications and shape of the diesel engine oil filter 5 to ensure that the chain can tightly wrap around the outside of the diesel engine oil filter 5. Then, the chain of the extended section of the adjustable locking component 4 is passed through the limiting support seat 203 and connected to the sprocket 202. Finally, the chain of the extended section is wound around the L-shaped limiting groove 102 to complete the installation. In use, the operator rotates the handle component 1 in the opposite direction. Rotating the handle component 1 drives the threaded screw 201 and sprocket 202 in the manual rotating assembly 2, thereby driving the chain-type adjustable locking assembly 4 to generate a reverse rotational force. The chain-type adjustable locking assembly 4 transmits rotational torque, causing the diesel engine oil filter 5 to rotate counterclockwise. The diesel engine oil filter 5 gradually loosens, allowing it to be smoothly removed from its mounting position on the diesel engine. Because the chain tightly locks the outer wall of the oil filter, the entire removal process is very smooth, preventing slippage or damage due to excessive rotation.
