Description

Technical Field

[0001] The utility model relates to the technical field of lubricating oil conduits, and in particular to a lubricating oil conduit. Background Art

[0002] The lubricating oil duct is an indispensable part of the lubrication system. Its main function is to transport the lubricating oil from the oil storage device to various lubrication points of mechanical equipment. These lubrication points may be bearings, gears, chains and other parts that need lubrication. Through the lubricating oil duct, it can be ensured that the lubricating oil is transported to these parts in a stable and continuous manner, providing sufficient lubrication for the equipment, reducing wear and friction, and thus extending the service life of the equipment.

[0003] The existing device has some disadvantages during use, for example: the existing lubricating oil conduit does not have a backflow prevention device. If the lubricating oil flows back in the conduit, it will bring impurities, pollutants or wear particles back to the oil storage container, causing the entire lubrication system to be contaminated. The backflow of lubricating oil will also cause the pressure in the conduit to be unstable, affecting the normal operation and lubrication effect of the equipment. Utility Model Content

[0004] The utility model aims to provide a lubricating oil conduit to solve the problem of lubricating oil backflow in the prior art.

[0005] The utility model provides the following technical solution: a lubricating oil conduit, comprising a conduit, wherein four support rods are fixedly sleeved on the inner side of the conduit, a sliding block is fixedly connected between the four support rods, a closing block is fixedly connected to the bottom ends of the four support rods, a valve body is fixedly connected to the top ends of the four support rods, a valve core is slidably sleeved on the valve body, the valve core is used to seal the valve body, a sliding rod is fixedly connected to the bottom end of the valve core, an end of the sliding rod away from the valve core passes through the sliding block and the closing block and is slidably connected to the sliding block and the closing block, and a closing assembly is provided on the closing block.

[0006] In the above scheme, when the lubricating oil starts to flow through the conduit and the pressure gradually increases, this pressure acts on the valve core, and the pressure of the lubricating oil pushes the valve core to move downward. As the valve core moves downward, it gradually leaves the flow channel of the valve body, allowing the lubricating oil to pass through. When the valve core moves downward, the sliding rod also slides down. As the sliding rod slides down, the closing assembly opens to allow the lubricating oil to pass through.

[0007] As a preferred embodiment of the above technical solution, the closing component includes a circulation groove distributed in an annular manner on the closing block, a closing cover is provided on the closing block, the closing cover is used to seal the circulation groove, a sliding hole is provided in the center of the closing cover, the closing cover is slidably connected to the sliding block through the sliding hole, an annular slider is fixedly connected to the bottom end of the closing cover, an annular sliding groove adapted to the size of the annular slider is provided in an annular manner at the top end of the closing block, the closing cover is rotatably connected to the closing block through the annular slider, and a rotating component is provided on the closing cover.

[0008] In the above scheme, the downward movement of the sliding rod causes the rotating assembly to drive the closing cover to rotate. As the closing cover rotates, the originally closed flow groove gradually opens to allow the lubricating oil to pass through. The sliding and rotation of the annular slider in the annular groove ensure that the closing cover can perform these movements smoothly.

[0009] As a preferred embodiment of the above technical solution, the rotating assembly includes two rotating grooves opened on the outer side of the bottom of the sliding rod, and two rotating sliders adapted to the size of the two rotating grooves are fixedly connected to the inner side of the sliding hole, and the two rotating sliders are respectively slidably connected to the corresponding two rotating grooves.

[0010] In the above scheme, as the sliding rod slides down, the two rotating sliders slide in the corresponding rotating slots respectively. Due to the shape design of the rotating slots, the sliding movement of the sliding rod will be converted into the rotational movement of the rotating sliders. This rotational movement is transmitted to the closing cover through the rotating sliders, causing the closing cover to rotate relative to the closing block. As the closing cover rotates, the originally closed flow groove gradually opens, allowing the lubricating oil to pass through.

[0011] As a preferred embodiment of the above technical solution, a spring is sleeved on the outer side of the sliding rod, and two ends of the spring correspond to and are fixedly connected to the bottom end of the valve core and the top end of the sliding block respectively.

[0012] In the above scheme, the spring can act as a buffer between the valve core and the sliding block, reducing the impact and damage to the entire device caused by sudden changes in lubricating oil pressure. When the lubricating oil stops flowing, the spring can restore the closing cover and the valve core to their initial positions through its own elastic force.

[0013] As a preferred embodiment of the above technical solution, a filter screen is fixedly connected to the top of the valve body.

[0014] In the above solution, the design of the filter screen can prevent impurities from entering the valve, thereby avoiding the influence of impurities on the sealing performance of the valve.

[0015] As a preferred embodiment of the above technical solution, the bottom end of the sliding rod is fixedly connected to a limiting block.

[0016] In the above solution, the limit block can accurately limit the moving range of the sliding rod to prevent it from exceeding the preset stroke, thereby ensuring the stability and reliability of the entire system.

[0017] Compared with the prior art, the beneficial effects of the utility model are:

[0018] In the utility model, the designs of the valve core and the closing cover both take sealing into consideration. The valve core can fit tightly against the valve body in the closed state to form a first seal, while the closing cover forms a second seal by its precise rotation and cooperation with the flow groove. This double sealing design ensures the unidirectional flow of the lubricating oil in the conduit and prevents the backflow of the lubricating oil, which is crucial for maintaining the stability of the conduit and preventing contamination.

DETAILED DESCRIPTION

[0026] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0027] Example 1

[0028] like Figure 1-Figure 6As shown, the utility model provides a technical solution: a lubricating oil conduit, including a conduit 10, four support rods 11 are fixedly sleeved inside the conduit 10, a sliding block 12 is fixedly connected between the four support rods 11, a closing block 13 is fixedly connected to the bottom ends of the four support rods 11, a valve body 14 is fixedly connected to the top ends of the four support rods 11, a valve core 15 is slidably sleeved on the valve body 14, the valve core 15 is used to block the valve body 14, a sliding rod 16 is fixedly connected to the bottom end of the valve core 15, and an end of the sliding rod 16 away from the valve core 15 passes through the sliding block 12 and the closing block 13 and slides between the sliding block 12 and the closing block 13 Dynamic connection, a closing assembly is arranged on the closing block 13. During specific use, the conduit 10 is used to connect the oil storage device and various lubrication points, and is a channel for the flow of lubricating oil. When the lubricating oil starts to flow through the conduit 10 and the pressure gradually increases, the pressure acts on the valve core 15. The pressure of the lubricating oil pushes the valve core 15 to move downward. As the valve core 15 moves downward, it gradually leaves the flow channel of the valve body 14, allowing the lubricating oil to pass through. When the valve core 15 moves downward, the sliding rod 16 also slides down. As the sliding rod 16 slides down, the closing assembly opens to allow the lubricating oil to pass through.

[0029] As an implementation method in this embodiment, Figure 2 and Figure 3 As shown, the closing component includes a circulation groove 20 distributed in an annular manner and opened on the closing block 13, and a closing cover 21 is arranged on the closing block 13. The closing cover 21 is used to block the circulation groove 20. A sliding hole 22 is opened in the center of the closing cover 21, and the closing cover 21 is slidably connected to the sliding block 12 through the sliding hole 22. The bottom end of the closing cover 21 is fixedly connected with an annular slider 23, and the top end of the closing block 13 is opened in an annular groove 24 adapted to the size of the annular slider 23. The closing cover 21 is rotatably connected to the closing block 13 through the annular slider 23. A rotating component is arranged on the closing cover 21. During specific use, the rotating component drives the closing cover 21 to rotate by the downward movement of the sliding rod 16. As the closing cover 21 rotates, the originally closed circulation groove 20 gradually opens to allow lubricating oil to pass through. The sliding and rotation of the annular slider 23 in the annular groove 24 ensure that the closing cover 21 can perform these movements smoothly.

[0030] As an implementation method in this embodiment, Figure 2 , Figure 3 and Figure 4As shown, the rotating assembly includes two rotating grooves 30 opened on the outer side of the bottom of the sliding rod 16, and two rotating sliders 31 adapted to the size of the two rotating grooves 30 are fixedly connected to the inner side of the sliding hole 22. The two rotating sliders 31 are respectively slidably connected with the corresponding two rotating grooves 30. During specific use, as the sliding rod 16 slides down, the two rotating sliders 31 slide in the corresponding rotating grooves 30 respectively. Due to the shape design of the rotating grooves 30, the sliding movement of the sliding rod 16 will be converted into the rotational movement of the rotating slider 31. This rotational movement is transmitted to the closing cover 21 through the rotating slider 31, so that the closing cover 21 rotates relative to the closing block 13. As the closing cover 21 rotates, the originally closed flow groove 20 gradually opens, allowing the lubricating oil to pass through.

[0031] As an implementation method in this embodiment, Figure 2 and Figure 3 As shown, a spring 40 is sleeved on the outer side of the sliding rod 16, and the two ends of the spring 40 correspond to the bottom end of the valve core 15 and the top end of the sliding block 12 for fixed connection respectively. During specific use, the spring 40 can play a buffering role between the valve core 15 and the sliding block 12, reducing the impact and damage to the overall device caused by the sudden change of the lubricating oil pressure. When the lubricating oil stops flowing, the spring 40 can restore the closing cover 21 and the valve core 15 to the initial position through its own elastic force.

[0032] As an implementation method in this embodiment, Figure 2 and Figure 3 As shown, a filter screen 50 is fixedly connected to the top of the valve body 14. During specific use, the design of the filter screen 50 can prevent impurities from entering the valve, thereby avoiding the influence of impurities on the sealing performance of the valve.

[0033] As an implementation method in this embodiment, Figure 2 and Figure 3 As shown, the bottom end of the sliding rod 16 is fixedly connected to a limit block 60. During specific use, the limit block 60 can accurately limit the movement range of the sliding rod 16 to prevent it from exceeding a preset stroke, thereby ensuring the stability and reliability of the entire system.

[0034] Working principle: When the lubricating oil starts to flow through the conduit 10, its pressure gradually increases. This increased pressure acts on the valve core 15, pushing the valve core 15 to move downward. As the valve core 15 moves downward, it gradually leaves the flow channel of the valve body 14, allowing the lubricating oil to pass through. When the valve core 15 moves downward, the sliding rod 16 connected to it also slides down. As the sliding rod 16 slides down, the two rotating sliders 31 slide in the corresponding rotating slide grooves 30 respectively. Due to the shape design of the rotating slide grooves 30, the downward movement of the sliding rod 16 is converted into a rotating slider The rotational movement of the valve core 15 and the sliding block 12 is transmitted to the closing cover 21 through the rotating slider 31, so that the closing cover 21 rotates relative to the closing block 13. As the closing cover 21 rotates, the originally closed flow groove 20 gradually opens to allow the lubricating oil to pass through. The spring 40 acts as a buffer between the valve core 15 and the sliding block 12 to reduce the impact and damage to the entire device caused by the sudden change of the lubricating oil pressure. When the lubricating oil stops flowing, the spring 40 can restore the closing cover 21 and the valve core 15 to the initial position through its own elastic force to ensure the sealing of the system.

[0035] The above embodiments are only used to illustrate the technical solution of the present invention, but not to limit it.
