Description

Technical Field

[0001] This utility model relates to the field of automotive oil pipe connector technology, specifically a quick-connect automotive oil pipe connector. Background Technology

[0002] In the automotive industry, the fuel line system is responsible for transporting critical fluids such as fuel and lubricating oil. The stability and sealing of its connections are crucial to the normal operation and safety of the vehicle. As a key component in fuel line connections, automotive fuel line fittings have always been a focus of industry research and improvement.

[0003] Traditional automotive fuel line connectors have several shortcomings in their connection methods. Common threaded connections rely solely on a simple threaded fit. During long-term vehicle operation, factors such as engine vibration, vehicle bumps, and internal pressure fluctuations within the fuel line can easily cause the connection between the fuel line and the connector to loosen. Once loosened, this not only leads to fuel leakage, affecting the normal operation of various vehicle systems, but also potentially poses safety hazards, such as a fire caused by leaked fuel igniting an open flame. In terms of sealing, traditional connectors have a relatively simple sealing structure, typically using only simple gaskets or sealant at the connection point. This sealing method is ill-suited to complex operating conditions, and its sealing performance gradually declines over time and with increased use, failing to effectively prevent fuel leakage. Utility Model Content

[0004] The purpose of this utility model is to provide a quick-connect automotive oil pipe connector, which solves the problem that the connection between the oil pipe and the connector is prone to loosening during long-term operation of the vehicle due to factors such as engine vibration, vehicle bumps, and internal pressure fluctuations of the oil pipe.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A quick-connect automotive oil pipe connector includes a body with a threaded groove inside; a sealing assembly for sealing the connection between the body and the oil pipe; and a fixing assembly for restricting the sealing assembly. The sealing assembly includes a fixing ring fixedly mounted on the surface of the body, a rotating ring rotatably connected inside the fixing ring, an arc-shaped groove on the surface of the rotating ring, a sliding rod slidably connected inside the arc-shaped groove, a connecting rod fixedly mounted outside the sliding rod, the connecting rod passing through the fixing ring, a connecting plate fixedly mounted on the surface of the connecting rod, and a sealing block fixedly mounted inside the connecting plate.

[0007] Preferably, a threaded ring is slidably connected to the surface of the body, and a limiting ring is fixedly installed on the surface of the threaded ring.

[0008] Preferably, a rotating shaft is rotatably connected to the surface of the main body, and a sliding rod is slidably connected inside the rotating shaft, with the sliding rod fixedly installed on the surface of the threaded ring.

[0009] Preferably, the fixing component includes: a limiting block, the limiting block being fixedly installed inside the fixing ring, the fixing block being fixedly installed inside the fixing ring, a slider being slidably connected inside the fixing block, and a plug rod being fixedly installed inside the slider, the plug rod being disposed inside the limiting block.

[0010] Preferably, a fixing spring is fixedly installed at the bottom of the slider, and the fixing spring is fixedly installed inside the fixing block.

[0011] Preferably, the surface of the fixing ring is provided with a groove, and the inside of the rotating shaft is provided with an annular groove.

[0012] Preferably, the surface of the sealing block is provided with a strip groove, and three sealing blocks are provided, all of which are arranged in a circular array with the center line of the fixing ring as the center.

[0013] By employing the above technical solution, this utility model provides a quick-connect automotive oil pipe connector. It possesses at least the following beneficial effects:

[0014] (1) By setting the sealing component, the oil pipe connection will resist the sliding of the threaded ring on the surface of the body. When the threaded ring slides, it will resist the sliding rod inside the rotating shaft, thereby driving the rotating shaft to rotate. When the rotating shaft rotates, it will pull the sliding rod to move closer to the surface of the rotating shaft. When the sliding rod moves, it will drive the connecting rod and the connecting plate to slide in the same direction. The sliding of the connecting plate will drive the movement of the sealing block, so that the sealing block is fixed on the surface of the limiting ring and seals the connection between the body and the oil pipe. This prevents the connection between the threaded body and the oil pipe from loosening under the long-term starting of the car, thus causing leakage. This improves the stability and sealing of the connection between the body and the oil pipe, enhances safety, and extends the service life of the components.

[0015] (2) By setting the fixing component, the slider needs to be manually pulled upward on the surface of the fixing block so that the slider drives the insertion rod to move upward. After the sealing component has sealed the connection between the body and the oil pipe, the slider can be manually released. At this time, the slider will be reset under the action of the fixing spring, so that the insertion rod is re-inserted into the inner side of the limiting block for fixing. This prevents the sealing component from being loosened or displaced due to the vibration caused by the car starting during use, thus improving the reliability of the sealing component and enhancing the stability of the sealing effect.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figure 1 - Figure 6 As shown, the present invention provides a technical solution: a quick-connect type automotive oil pipe connector, including a body 1, the body 1 having a threaded groove 2 inside;

[0026] It also includes a sealing assembly 3 for sealing the connection between the body 1 and the oil pipe;

[0027] Fixing component 4 is used to restrict sealing component 3;

[0028] First, the sealing assembly 3 includes: a fixing ring 31, which is fixedly installed on the surface of the body 1. A rotating ring 32 is rotatably connected inside the fixing ring 31. An arc-shaped groove 320 is opened on the surface of the rotating ring 32. A sliding rod 33 is slidably connected inside the arc-shaped groove 320. A connecting rod 34 is fixedly installed on the outside of the sliding rod 33. The connecting rod 34 passes through the fixing ring 31. A connecting plate 35 is fixedly installed on the surface of the connecting rod 34. A sealing block 36 is fixedly installed inside the connecting plate 35. By fixing the limiting ring 38 with the sealing block 36, it is possible to prevent the body 1 from loosening when connected to the oil pipe screw, and it is also possible to seal the connection between the body 1 and the oil pipe.

[0029] Secondly, a threaded ring 37 is slidably connected to the surface of the main body 1, a limiting ring 38 is fixedly installed on the surface of the threaded ring 37, a rotating shaft 39 is rotatably connected to the surface of the main body 1, a sliding rod 310 is slidably connected inside the rotating shaft 39, and the sliding rod 310 is fixedly installed on the surface of the threaded ring 37. When the rotating shaft 39 rotates, it can drive the rotating ring 32 inside the fixed ring 31 to rotate.

[0030] Furthermore, the fixing component 4 includes: a limiting block 41, which is fixedly installed inside the fixing ring 31; a fixing block 42 is fixedly installed inside the fixing ring 31; a slider 43 is slidably connected inside the fixing block 42; and a plug rod 44 is fixedly installed inside the slider 43. The plug rod 44 is located inside the limiting block 41. The plug rod 44 can be restricted by multiple sets of limiting blocks 41 to prevent accidental rotation of the rotating ring 32.

[0031] Furthermore, a fixing spring 46 is fixedly installed at the bottom of the slider 43. The fixing spring 46 is fixedly installed inside the fixing block 42. The fixing spring 46 at the bottom of the slider 43 can achieve the effect of resetting after the slider 43 has finished sliding.

[0032] Finally, the surface of the fixing ring 31 has a groove 3100, which facilitates connection with the fixing block 42. The inside of the rotating shaft 39 has an annular groove 390, which allows the rotating shaft 39 to rotate when the sliding rod 310 slides. The surface of the sealing block 36 has a strip groove 360, which allows the limiting ring 38 to be fixed. There are three sealing blocks 36, and the three sealing blocks 36 are arranged in a circular array with the center line of the fixing ring 31 as the center. The three sealing blocks 36 can be used to make the surface of the connection between the body 1 and the oil pipe match when the sealing blocks 36 are movably spliced.

[0033] In use, the quick-connect automotive oil pipe connector of this utility model aligns the oil pipe with one end of the body 1. Utilizing the threaded groove 2 inside the body 1, the oil pipe is initially connected to the body 1 via a threaded connection. This threaded connection method ensures a relatively stable connection between the oil pipe and the body 1, and facilitates installation and disassembly. During connection, the oil pipe first engages with the threaded ring 37, and during connection, the threaded ring 37 slides against the surface of the body 1. As the threaded ring 37 slides, it abuts against the sliding rod 310, which slides within the annular groove 390 inside the rotating shaft 39, thereby causing the rotating shaft 39 to rotate inside the fixed ring 31. When the rotating shaft 39 rotates, it pulls the sliding rod 33 closer to the fixed ring 31 through the arc-shaped groove 320 on its surface. The surface of the rotating shaft 39 moves, and when the slide rod 33 moves, it will drive the connecting rod 34 and the connecting plate 35 to slide in the same direction as the slide rod 33. When the threaded ring 37 slides, it will also drive the limiting ring 38 to slide. When the limiting ring 38 slides, the sliding of the connecting plate 35 will drive the sealing block 36 to move, so that the sealing block 36 is fixed to the surface of the limiting ring 38 through the inner groove 360, and seals the connection between the body 1 and the oil pipe. This prevents the threaded connection between the body 1 and the oil pipe from loosening under long-term starting of the car, thus preventing leakage. This improves the stability and sealing of the connection between the body 1 and the oil pipe, enhances safety, and extends the service life of the components.

[0034] When the rotation of the shaft 39 drives the rotating ring 32 to rotate, the slider 43 needs to be manually pulled upward on the surface of the fixed block 42 first, so that the slider 43 drives the insertion rod 44 to move upward. When the insertion rod 44 moves upward, the restriction block 41 will release the restriction on the insertion rod 44. After the sealing assembly 3 has sealed the connection between the body 1 and the oil pipe, the slider 43 can be manually released. At this time, the slider 43 will be reset under the action of the fixed spring 46, so that the insertion rod 44 is re-inserted into the inner side of the restriction block 41 for fixation. This prevents the sealing assembly 3 from loosening and displacing due to the vibration caused by the car starting during use, thus improving the reliability of the sealing assembly 3 and enhancing the stability of the sealing effect.
