Description

Technical Field

[0001] This utility model relates to the field of quick-connect fittings for automotive pipelines, specifically a quick-connect fitting for automotive pipelines. Background Technology

[0002] Automotive piping systems are a crucial network of channels for transporting various working media within a vehicle, much like the "blood vessels" of the human body. They are responsible for the safe and reliable transmission of liquids or gases such as fuel, engine oil, brake fluid, coolant, refrigerant, compressed air, and hydraulic fluid between key components such as the engine, transmission, braking system, fuel supply, air conditioning, and turbocharger. Quick-connect fittings are the most convenient plug-and-play connection method, especially advantageous in challenging or difficult-to-access environments where pipe connections are difficult. Pipe-to-pipe connections are mostly achieved through quick-connect fittings for a sealed connection. The fittings consist of a connector and a fitting attached to the connector. Assembling the connector and fitting onto the pipe establishes connectivity. However, current automotive piping quick-connect fittings still have the following problems during use: 1. When the quick-connect fitting has a bent head, the connection of the fitting body is prone to loosening due to the influence of external pipeline forces, and it is not convenient to rotate the fitting body during installation. 2. During vehicle maintenance, it is necessary to disassemble the connecting structure to determine the connection between the connector body and the car connector. However, repeated disassembly and reassembly will inevitably reduce its sealing performance, thus affecting normal use. Therefore, there is an urgent need for a quick-connect fitting for automotive piping to improve the above problems. Utility Model Content

[0029] Reference Figure 1 The connector body 1 and the car connector 23 are threaded together. In this embodiment, the car connector 23 serves to install the connector plate 1.

[0030] The implementation principle of this embodiment is as follows: During use, one end of the pipeline is inserted into the inside of the limiting cylinder 10. After the pipeline is inserted into the inside of the limiting cylinder 10, the high-temperature welding piece 5 is in a solid state. Therefore, the connecting cylinder 3 can rotate inside the connector body 1 to quickly adjust the angle of the pipeline. After the angle of the pipeline is adjusted, the connector body 1 is inserted into the inside of the car connector 23. The operator uses a tool to drive the connector body 1 to rotate. The connector body 1 and the car connector 23 are connected by threads. As the connector body 1 rotates continuously, the connector body 1 will gradually enter the inside of the car connector 23 until the connector body 1 is completely inside the car connector 23, thus completing the installation of the connector body 1. After the installation of the connector body 1 is completed, the connecting cylinder 3 needs to be heated using heating equipment. During this process, the temperature of the connecting cylinder 3 will rise rapidly until the high-temperature welding sheet 5 begins to melt. After the high-temperature welding sheet 5 has completely melted, it will change from solid to liquid. At this point, heating is stopped, and the melted high-temperature welding sheet 5 is allowed to solidify again. After the high-temperature welding sheet 5 solidifies again, the connector body 1 and the connecting cylinder 3 will be welded together (the high-temperature welding sheet 5 is a pre-made welding agent; heating it and waiting for it to cool will create a welding effect). Before the pipe connection installation, the acrylic cylinder 18 is fitted onto the outside of the car connector 23. The cotton ring 21 can also be installed inside the acrylic cylinder 18. After the pipe installation is completed, the acrylic cylinder 18 is pushed to slide on the outside of the car connector 23. As the acrylic cylinder 18 slides continuously, the distance between the acrylic cylinder 18 and the limiting ring 15 will gradually decrease until the acrylic cylinder 18 and the limiting ring 15 are in contact with each other. Then, the worker passes the fixing screw 17 through the mounting hole 16 and into the screw hole 19, and uses a tool to tighten it. The acrylic cylinder 18 is fixed to the outside of the car connector 23 so as to observe the connection between the car connector 23 and the connector body 1. During vehicle inspection, the cotton spinning ring 21 may exhibit two different characteristics: If the color of the cotton spinning ring 21 remains unchanged and remains white, it indicates that there is no abnormality at the connection between the car connector 23 and the connector body 1, and the structure does not need to be disassembled and can be used normally; if the color of the cotton spinning ring 21 changes, it indicates that there is an abnormality at the connection between the car connector 23 and the connector body 1, and the structure connected to it needs to be removed and repaired. After the repair is completed, a new cotton spinning ring 21 should be replaced, and the structure should be installed. After confirming that everything is normal, the vehicle can be used normally.
