Description

Technical Field

[0001] This utility model relates to the field of oil inlet pipe connection structure, specifically to a leak-proof connection structure for a turbocharger lubrication oil inlet pipe. Background Technology

[0002] The turbocharger lubrication inlet pipe connection structure is a key component that ensures the stable delivery of engine oil from the engine oil circuit to the turbocharger, achieving lubrication and cooling. Its design must take into account sealing performance, pressure resistance, vibration resistance, and ease of installation.

[0003] Traditional turbocharger lubrication inlet pipe connections mostly rely on threaded connections and simple sealing rings for sealing, which is ineffective in preventing leaks. The internal bearings and rotor shaft of the turbocharger rely on engine oil to form an oil film for lubrication and cooling. If the inlet pipe leaks, the bearings and rotor shaft will come into direct contact, causing the coefficient of friction to rise sharply and generate high temperatures. This can lead to melting of the metal surfaces and adhesive wear. In addition, leaked engine oil may drip onto high-temperature components and splash onto engine wiring harnesses and plastic parts, spreading the fire and endangering the safety of the entire vehicle.

[0004] Therefore, it is necessary to invent a leak-proof connection structure for the turbocharger lubrication inlet pipe to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide a leak-proof connection structure for the lubrication inlet pipe of a turbocharger. This is achieved by sleevering a high-temperature resistant connecting pipe over a high-temperature resistant guide tube, using two sets of sealing rings on the outside of the guide tube to enhance the seal. Then, rotating the rotating sleeve tightens the threads of the fixing sleeve on the outside of the high-temperature resistant connecting pipe. After the fixing sleeve is screwed into the rotating sleeve, the connecting sleeve is inserted into the mating sleeve, thereby compressing the compression block and the clamping block below. This causes the clamping block to press against the outside of the high-temperature resistant connecting pipe, positioned behind the sealing rings, thus strengthening the seal between the sealing rings and the high-temperature resistant connecting pipe. This also enhances the overall connection strength, thus solving the aforementioned problem. The background technology mentions that traditional turbocharger lubrication inlet pipe connection structures mostly rely on threaded connections and simple sealing rings for sealing, which has poor leak prevention effect. The internal bearings and rotor shaft of the turbocharger rely on the oil film formed by the engine oil for lubrication and cooling. If the oil inlet pipe leaks, the bearing and rotor shaft will come into direct contact, the coefficient of friction will increase sharply, and high temperature will be generated, causing the metal surface to melt and adhesive wear. At the same time, the leaked oil may drip onto the high-temperature components, and the leaked oil may splash onto the engine wiring harness and plastic parts, expanding the fire and endangering the safety of the entire vehicle.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a leak-proof connection structure for a turbocharger lubrication inlet pipe, including a connector for connecting the inlet pipe; A connector is installed at one end of the oil guide tube. A fixing block is fixedly connected to the outer end of the connector. A high-temperature resistant conduit is fixedly connected to the outer side of the fixing block. A sealing groove is opened on the outer side of the high-temperature resistant conduit. A sealing ring is embedded in the inside of the sealing groove. A rotating sleeve is rotatably connected to the outside of the high-temperature resistant conduit. A connecting sleeve is fixedly connected to the outside of the high-temperature resistant conduit. A sealing element is embedded on the inner side of the connecting sleeve. A high-temperature resistant connecting pipe is movably sleeved outside a high-temperature resistant conduit. A fixing sleeve is fixedly connected to the outside of the high-temperature resistant connecting pipe, and a mating sleeve is fixedly connected to the inside of the fixing sleeve. A pressing block is slidably connected inside the mating sleeve, and a clamping block is fixedly connected to the lower end of the pressing block, and the clamping block is in contact with the outer wall of the high-temperature resistant connecting pipe.

[0007] Preferably, a groove is provided on the outer rear end of the high-temperature resistant conduit, and the rear side of the rotating sleeve is located inside the groove.

[0008] Preferably, the rotating sleeve has an internal thread inside, and the mating sleeve has an external thread outside, and the rotating sleeve and the mating sleeve are threadedly connected.

[0009] Preferably, the inner side of the docking sleeve is provided with a docking groove, and the connecting sleeve is movably inserted into the inner side of the docking sleeve.

[0010] Preferably, the front side of the connecting sleeve is arc-shaped, the outer side of the extrusion block is at an angle, and the front side of the connecting sleeve abuts against the inner side of the extrusion block.

[0011] Preferably, a connecting block is fixedly connected to one side of the extrusion block, and a spring is fixedly connected to the lower part of the connecting block, with the spring located in the inner cavity of the mating sleeve.

[0012] The technical effects and advantages provided by this utility model in the above technical solution are as follows: This invention, through the arrangement of a high-temperature resistant conduit, sealing ring, rotating sleeve, high-temperature resistant connecting pipe, fixing sleeve, mating sleeve, extrusion block, and clamping block, not only improves stability but also enhances the leak-proof effect. By sleeved on the high-temperature resistant conduit, the sealing performance is enhanced by two sets of sealing rings on the outside of the high-temperature resistant conduit. Then, rotating the rotating sleeve causes the threads of the fixing sleeve on the outside of the high-temperature resistant connecting pipe to tighten. After the fixing sleeve is screwed into the rotating sleeve, the connecting sleeve is inserted into the mating sleeve, thereby compressing the extrusion block and the clamping block below. This causes the clamping block to press on the outside of the high-temperature resistant connecting pipe, located behind the sealing ring, thus enhancing the sealing performance between the sealing ring and the high-temperature resistant connecting pipe, and also strengthening the overall connection strength.

[0016] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0017] This utility model provides, for example Figure 1-6 The present invention provides a leak-proof connection structure for a turbocharger lubrication inlet pipe, including a connector 1 for connecting the inlet pipe; Connector 1 is installed at one end of oil guide pipe 2. A fixing block 3 is fixedly connected to the outer end of connector 1. A high-temperature resistant conduit 4 is fixedly connected to the outer side of fixing block 3. A sealing groove 5 is opened on the outer side of the high-temperature resistant conduit 4. A sealing ring 6 is embedded inside the sealing groove 5. A rotating sleeve 8 is rotatably connected to the outer side of the high-temperature resistant conduit 4. A connecting sleeve 10 is fixedly connected to the outer side of the high-temperature resistant conduit 4. A sealing element 11 is embedded on the inner side of the connecting sleeve 10. The high-temperature resistant connecting pipe 12 is movably sleeved outside the high-temperature resistant conduit 4. A fixed sleeve 13 is fixedly connected to the outside of the high-temperature resistant connecting pipe 12, and a mating sleeve 14 is fixedly connected to the inside of the fixed sleeve 13. A pressing block 17 is slidably connected inside the mating sleeve 14. A clamping block 20 is fixedly connected to the lower end of the pressing block 17 and contacts the outer wall of the high-temperature resistant connecting pipe 12. By sleeved on the high-temperature resistant connecting pipe 12 outside the high-temperature resistant conduit 4, the sealing performance is enhanced by the two sets of sealing rings 6 outside the high-temperature resistant conduit 4. Then, the rotating sleeve 8 is rotated to drive the fixed sleeve 13 outside the high-temperature resistant connecting pipe 12 to be threaded and tightened. After the fixed sleeve 13 is screwed into the rotating sleeve 8, the connecting sleeve 10 is inserted into the mating sleeve 14, thereby pressing the pressing block 17 and the clamping block 20 below, so that the clamping block 20 is pressed on the outside of the high-temperature resistant connecting pipe 12 and located behind the sealing ring 6, thereby enhancing the sealing performance between the sealing ring 6 and the high-temperature resistant connecting pipe 12, and also enhancing the overall connection strength.

[0018] like Figure 3 As shown, a groove 7 is provided on the outer side of the rear end of the high-temperature resistant conduit 4. The rear side of the rotating sleeve 8 is located inside the groove 7. The rotating sleeve 8 is limited to rotating within the groove 7 on the outer side of the high-temperature resistant conduit 4, so that the rotating sleeve 8 is threadedly connected to the mating sleeve 14.

[0019] like Figure 3 and Figure 5 As shown, the rotating sleeve 8 has an internal thread 9 inside, and the mating sleeve 14 has an external thread 15 outside. The rotating sleeve 8 and the mating sleeve 14 are threadedly connected. When the mating sleeve 14 is attached to the front side of the rotating sleeve 8, rotating the rotating sleeve 8 will cause the mating sleeve 14 to be tightened into the rotating sleeve 8, thereby strengthening the connection between the rotating sleeve 8 and the high-temperature resistant connecting pipe 12.

[0020] like Figure 4 and Figure 5 As shown, the inner side of the docking sleeve 14 is provided with a docking groove 16. The connecting sleeve 10 is movably inserted into the inner side of the docking sleeve 14. When the docking sleeve 14 is threaded into the rotating sleeve 8, the connecting sleeve 10 outside the high temperature resistant conduit 4 is inserted into the docking groove 16 inside the docking sleeve 14, thereby squeezing the squeezing block 17 and pushing the clamping block 20.

[0021] like Figure 5 and Figure 6 As shown, the front side of the connecting sleeve 10 is arc-shaped, and the outer side of the extrusion block 17 is beveled. The front side of the connecting sleeve 10 abuts against the inner side of the extrusion block 17. Because the front side of the connecting sleeve 10 is arc-shaped, it can push the beveled outer side of the extrusion block 17, so that the extrusion block 17 pushes the clamping block 20 below to press against the outside of the high-temperature resistant connecting pipe 12, thereby enhancing the sealing and stability.

[0022] like Figure 5 and Figure 6As shown, a connecting block 18 is fixedly connected to one side of the extrusion block 17, and a spring 19 is fixedly connected to the lower part of the connecting block 18. The spring 19 is located in the inner cavity of the mating sleeve 14. When the extrusion block 17 loses the front extrusion of the connecting sleeve 10, the spring 19 below the connecting block 18 rebounds and pulls the clamping block 20 back into the interior of the mating sleeve 14.

[0023] The working principle of this practical application is as follows: First, two sets of sealing rings 6 are placed inside the sealing groove 5 outside the high-temperature resistant conduit 4. Then, the high-temperature resistant connecting pipe 12 is placed outside the high-temperature resistant conduit 4. Next, when the mating sleeve 14 is attached to the front side of the rotating sleeve 8, the rotating sleeve 8 is rotated, thereby driving the mating sleeve 14 to tighten into the interior of the rotating sleeve 8, thus strengthening the connection between the rotating sleeve 8 and the high-temperature resistant connecting pipe 12. When the thread of the mating sleeve 14 enters the rotating sleeve 8, the connecting sleeve 10 outside the high-temperature resistant conduit 4 is inserted into the mating groove 16 inside the mating sleeve 14. Because the front side of the connecting sleeve 10 is arc-shaped, it can push the outer angle of the extrusion block 17, allowing the extrusion block 17 to push the clamping block 20 below to press against the outside of the high-temperature resistant connecting pipe 12, thereby strengthening the sealing and stability between the high-temperature resistant conduit 4 and the high-temperature resistant connecting pipe 12. In this way, the use process of the anti-leakage connection structure of the turbocharger lubrication inlet pipe is completed.

[0024] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
