DETAILED DESCRIPTION

[0020] The technical scheme of the utility model will be further specifically described below by combining with the drawings, and the described embodiments are only part of the embodiments of the utility model, not all the embodiments.

[0021] Embodiment 1: refer to Figures 1 to 4The adjusting ring 6 is made of high-strength material, which not only can withstand high pressure, but also can maintain its performance in various harsh working environments without deformation or damage. The connection between the adjusting ring 6 and the oil injection needle 9 is still firm even under high pressure or frequent adjustment, reducing the possibility of loosening. The material and surface treatment of the oil injection needle 9 are carefully selected and treated to ensure stability and corrosion resistance during long-term operation, even under the chemical action of oil.

[0022] The embedded design between the limiting block 7, the limiting groove 8, and the buckle 2 is another important feature of the connection between the adjusting ring 6 and the oil injection needle 9. This design not only provides structural stability, but also allows fine adjustment during the adjustment process, enabling precise control of the position of the oil injection needle 9 within the adjusting ring 6. This precise control is crucial for fine adjustment of oil output, ensuring consistency and reliability of oil output. The limiting block 7 maintains a stable embedded state under different pressures, while the design of the limiting groove 8 and the buckle 2 ensures the fixation of the oil injection needle 9 within the adjusting ring 6, preventing displacement under pressure changes.

[0023] The inner groove 11 between the first protrusion 10 and the second protrusion 13 on one side of the bottom of the oil injection needle 9 is one of the designs to enhance the stability of the oil injection needle. This inner groove 11 provides an additional support point for the oil injection needle, enabling it to maintain stability under high pressure or vibration environment without position deviation due to external factors. The inner groove 11 disperses stress, reducing the possibility of fatigue damage of the oil injection needle 9 after long-term work, thereby prolonging its service life. The sealing ring 12 embedded in the inner groove 11 is a key component to prevent oil leakage. The sealing ring 12 is made of oil-resistant material, which can maintain good sealing performance under oil pressure, preventing oil leakage from the connection. The sealing ring 12 is tightly fitted to the viewer 5.

[0024] The inspector 5 is connected to the sliding cavity 3 formed inside the oil injection needle 9, which is precisely adjusted in the sliding cavity 3 to achieve precise control of oil output. The design of the sliding cavity 3 also takes into account the reduction of friction and wear to improve the response speed and service life of the adjusting mechanism. This design allows the oil injection needle 9 to move smoothly during adjustment, reducing wear caused by friction and improving the efficiency and durability of the entire adjusting mechanism. The anti-slip pattern 15 on the surface of the adjusting ring 6 improves the operator's grip and the strength of the adjusting ring structure. These anti-slip patterns 15 are designed with ergonomics in mind, allowing the operator to hold the adjusting ring 6 firmly and make precise adjustments even in oily or slippery environments. The vertical concave structure of the anti-slip pattern 15 not only increases the friction between the adjusting ring 6 and the operator to prevent slipping, but also enhances the structural strength of the adjusting ring 6, making it less likely to deform or damage when subjected to large torque.

[0025] Example 2: Reference Figures 1 to 4 This embodiment has the same main structure as Example 1, with some improvements to the adjusting structure of the oil feeder. The adjusting ring 6 is made of high-strength material that can withstand high pressure and maintain its performance in harsh environments, making it less likely to deform or damage. At the connection, a clamping slot is used to ensure that the connection between the adjusting ring 6 and the oil injection needle 9 remains secure even under high pressure or frequent adjustments, significantly reducing the risk of loosening. The oil injection needle 9, as a key component for precise oil feeding, has its material and surface treatment carefully selected and treated to maintain stability and corrosion resistance during long-term operation, even under the chemical action of oil.

[0026] The embedding design between the limiting block 7 on the upper part of the adjusting ring 6 and the limiting slot 8 and the buckle 2 on one side of the oil injection needle 9 is an important feature of the connection part. This design not only enhances the stability of the structure, but also allows for fine adjustment during the adjustment process, allowing the position of the oil injection needle 9 within the adjusting ring 6 to be precisely controlled, which is crucial for achieving fine adjustment of oil output and ensuring consistency and reliability of oil output. The design of the limiting block 7 takes into account the principles of mechanics, allowing it to maintain a stable embedding state under different pressures, while the design of the limiting slot 8 and the buckle 2 ensures the fixation of the oil injection needle 9 within the adjusting ring 6, preventing displacement under pressure changes.

[0027] The inner groove 11 between the first protrusion 10 and the second protrusion 13 on the bottom side of the oil injection needle 9 is one of the designs to enhance the stability of the oil injection needle. This inner groove 11 provides an additional support point for the oil injection needle, allowing it to remain stable under high pressure or vibration environments without shifting position due to external factors. This design also helps to distribute stress and reduce fatigue damage that may occur after long periods of use, thereby extending the service life of the oil injection needle 9. The sealing ring 12 embedded in the inner groove 11 is a key component for preventing oil leakage. Made of oil-resistant material, the sealing ring 12 can maintain good sealing performance under oil pressure, preventing oil leakage from the connection. The sealing ring 12 tightly fits the viewer 5, ensuring the cleanliness and efficiency of the oiling process, avoiding environmental pollution and resource waste that may be caused by oil leakage.

[0028] The sliding cavity 3 formed inside the oil injection needle 9 and the viewer 5 allows the oil injection needle 9 to adjust its position within the sliding cavity 3, thereby achieving precise control over oil output. The design of the sliding cavity 3 also takes into account reducing friction and wear to improve the response speed and service life of the adjustment mechanism. This design allows the oil injection needle 9 to move smoothly during adjustment, reducing wear caused by friction and improving the overall efficiency and durability of the adjustment mechanism. The anti-slip pattern 15 on the surface of the adjustment ring 6 is designed to improve the operator's grip and the structural strength of the adjustment ring. These anti-slip patterns 15 are designed with ergonomics in mind, allowing the operator to hold the adjustment ring 6 firmly and accurately even in oily or slippery environments. The vertical inner concave structure of the anti-slip pattern 15 not only increases the friction between the adjustment ring 6 and the operator to prevent slipping, but also enhances the structural strength of the adjustment ring 6, making it less likely to deform or damage when subjected to large torques.

[0029] The top opening 16 at the bottom of the oil injection needle 9 is the core part that comes into contact with the oil, and its design is crucial as it directly affects the flow characteristics of the oil and the accuracy of the oiling. The shape of the top opening 16 is designed to be streamlined to reduce resistance when the oil flows out, ensuring that the oil can flow out uniformly and continuously. This design helps to avoid oil spraying or dripping, thereby ensuring the stability and reliability of the oil supply. The size of the top opening 16 is also precisely calculated to accommodate different oil viscosity and flow requirements, ensuring optimal oiling performance under various working conditions.

[0030] To enhance the sealing and durability of the top 16, a resilient member 14 is designed around its perimeter. The resilient member 14 is typically made of oil-resistant rubber or other high-performance elastic materials that have good oil resistance, temperature resistance, and aging resistance. These materials can form a sealing ring around the top 16, effectively preventing oil leakage. At the same time, the resilient member 14 can also absorb the impact caused by pressure changes or mechanical vibrations, protecting the top 16 from damage, extending the service life of the oil injection needle 9, and reducing maintenance costs.

[0031] The middle annular surface of the inspector 5 is designed as a stepped block 4. This design not only improves the matching accuracy with the adjusting ring 6, but also enhances the stability of the structure. The stepped shape of the stepped block 4 allows multiple positioning points to be formed on the adjusting ring 6, which can provide multiple preset positions during adjustment, making the adjustment of the oil injection needle 9 more accurate and convenient. This design allows the operator to quickly adjust the position of the oil injection needle 9 to adapt to different working conditions, improving work efficiency. The design of the stepped block 4 also helps to distribute the pressure on the inspector 5, enhancing its structural strength, ensuring stability during long-term operation, and reducing the risk of damage due to pressure concentration.

[0032] Example 3: Reference Figures 1 to 4 This embodiment has the same main structure as Examples 1 or 2, and is improved based on Examples 1 and 2. The adjusting ring 6 is made of high-strength material that can withstand extreme pressure and maintain its performance in harsh working conditions, without easily deforming or damaging. At the connection between the adjusting ring 6 and the oil injection needle 9, a precisely designed thread or clamping groove is used. This design ensures that the connection between the two remains firm even under high pressure or frequent adjustment, significantly reducing the risk of loosening. The oil injection needle 9, as a key component for precise oil feeding, has its material and surface treatment carefully selected and treated to maintain stability and corrosion resistance during long-term operation, even under the chemical action of oil.

[0033] The embedding design between the limiting block 7 on the upper part of the adjusting ring 6 and the limiting groove 8 on one side of the oil injection needle 9 and the buckle 2 is an important feature of the connection part. This design not only enhances the stability of the structure, but also allows fine adjustment during adjustment, so that the position of the oil injection needle 9 in the adjusting ring 6 can be accurately controlled, which is crucial for fine adjustment of oil output, ensuring the consistency and reliability of oil output. The design of the limiting block 7 takes into account the mechanical principle, which can maintain a stable embedding state under different pressures, while the design of the limiting groove 8 and the buckle 2 ensures the fixation of the oil injection needle 9 in the adjusting ring 6, preventing displacement when the pressure changes.

[0034] The inner groove 11 between the first protrusion 10 and the second protrusion 13 on the bottom side of the oil injection needle 9 is one of the designs to enhance the stability of the oil injection needle. This inner groove 11 provides an additional support point for the oil injection needle, allowing it to remain stable under high pressure or vibration environments without shifting position due to external factors. This design also helps to distribute stress and reduce fatigue damage that may occur after long periods of use, thereby extending the service life of the oil injection needle 9. The sealing ring 12 embedded in the inner groove 11 is a key component for preventing oil leakage. Made of oil-resistant material, the sealing ring 12 can maintain good sealing performance under oil pressure, preventing oil leakage from the connection. The sealing ring 12 tightly fits the viewer 5, ensuring the cleanliness and efficiency of the oiling process and avoiding environmental pollution and resource waste that may be caused by oil leakage.

[0035] The sliding cavity 3 formed inside the oil injection needle 9 and the viewer 5 allows the oil injection needle 9 to make precise position adjustments within the sliding cavity 3, thereby achieving precise control over oil output. The design of the sliding cavity 3 also takes into account reducing friction and wear to improve the response speed and service life of the adjustment mechanism. This design allows the oil injection needle 9 to move smoothly during adjustment, reducing wear caused by friction and improving the overall efficiency and durability of the adjustment mechanism. The anti-slip pattern 15 on the surface of the adjustment ring 6 is designed to improve the operator's grip and the structural strength of the adjustment ring. These anti-slip patterns 15 are designed with ergonomics in mind, allowing the operator to hold the adjustment ring 6 firmly even in oily or slippery environments, making precise adjustment operations possible. The vertical inner concave structure of the anti-slip pattern 15 not only increases the friction between the adjustment ring 6 and the operator, preventing slipping, but also enhances the structural strength of the adjustment ring 6, making it less prone to deformation or damage when subjected to large torques.

[0036] The vertical pattern 1 on the upper end of the oil injection needle 9 not only provides a good visual effect, but also increases the friction between the oil injection needle 9 and the adjustment ring 6, making the oil injection needle 9 less likely to slip during adjustment and improving the accuracy of adjustment. The design of the vertical pattern 1 also helps the operator better grasp the oil injection needle 9, allowing them to hold it firmly even in oily or slippery environments. The buckle 2 below the vertical pattern 1 serves to fix the position of the vertical pattern 1, ensuring the stability of the oil injection needle 9 during adjustment. The design of the buckle 2 takes into account the need for quick disassembly and installation, making it easier to maintain and replace the oil injection needle 9. The vertical pattern 1 closely fits the upper end of the adjustment ring 6, and this close fitting design helps to improve the mechanical strength and adjustment accuracy of the entire structure, ensuring that the oil injection needle 9 can maintain precise positioning even in high-pressure environments.

[0037] The surface of the adjusting ring 6 is designed with anti-slip patterns 15, which are vertical concave structures. These anti-slip patterns 15 not only increase the friction between the adjusting ring 6 and the operator, preventing slipping during operation, but also enhance the structural strength of the adjusting ring 6. The design of the anti-slip patterns 15 takes into account ergonomics, allowing the operator to hold the adjusting ring 6 firmly and perform precise adjustment operations even in oily or slippery environments. This design helps to improve the safety of the operation and reduce the risk of accidents caused by slipping. In addition, the concave structure of the anti-slip patterns 15 also reduces the accumulation of dirt and oil, making it easier to clean and maintain, and improving the service life and maintenance convenience of the adjusting ring 6. The concave structure design also helps to distribute the pressure on the adjusting ring 6, enhancing its structural strength and ensuring stability during long-term operation.
