Detailed Implementation

[0027] like Figures 1 to 7 As shown, this utility model discloses a quick-installation duct assembly, including a duct body 1, a connector 2, a fixing ring 3, and a fixing member 4. The connector 2 is connected to the duct body 1, and the two duct bodies 1 are connected through the connector 2. The fixing ring 3 is sleeved at the connection between the duct body 1 and the connector 2, and the duct body 1 and the connector 2 are fixed by the fixing ring 3. The fixing member 4 is used to fix the fixing ring 3. The two duct bodies 1 are connected through the connector 2, and after connection, they are fixed by the fixing ring 3 and the fixing member 4, which reduces the complexity of connection and increases construction efficiency.

[0028] In this utility model, the connector 2 is in the shape of a straight tube or a bent tube. The straight tube connector 2 is used to increase the overall length after the two air duct bodies 1 are connected. The bent tube connector 2 is used to change the connection direction of the air duct body 1. The bending angle can be 90°, 45°, etc.

[0029] The connector 2 is provided with a plug-in part 5, and the duct body 1 is provided with a plug-in groove 6. The plug-in part 5 is inserted into the plug-in groove 6, and the plug-in part 5 and the plug-in groove 6 are interference-fitted. The plug-in part 5 is provided with a positioning groove 7, and the plug-in groove 6 is provided with a positioning block 8. The positioning block 8 is locked in the positioning groove 7. The connector 2 and the duct body 1 are connected by inserting the plug-in part 5 into the plug-in groove 6. The interference fit between the plug-in part 5 and the plug-in groove 6 increases the stability of the connector 2 after it is connected to the duct assembly. When the plug-in part 5 is inserted into the plug-in groove 6, the positioning of the connector 2 and the duct body 1 is achieved by the cooperation of the positioning block 8 and the positioning groove 7.

[0030] Both the connector 2 and the duct body 1 are provided with limiting blocks 9 at the connection end, and the fixing ring 3 is provided with limiting grooves 10. After the connector 2 and the duct body 1 are connected, both limiting blocks 9 are limited in the limiting grooves 10. The fixing ring 3 is provided with a fixing part 11 and a fixing hole 12. The fixing member 4 passes through the fixing hole 12 to fasten the two fixing rings 3. The setting of the fixing rings 3 further increases the connection stability between the connector 2 and the duct body 1 and prevents the connector 2 from separating from the duct body 1. After the two fixing rings 3 limit the connector 2 and the duct body 1, the two fixing rings 3 are locked by the fixing member 4 to prevent the fixing rings 3 from separating.

[0031] The fixing component 4 includes a fixing post 13, a fixing nut 14, a pressing post 15, a fixing claw 16, and a pull ring 26. The fixing post 13 is provided with a sliding groove 17, and the pressing post 15 is slidably disposed in the sliding groove 17. The pressing post 15 is provided with a protruding ring 18, and a groove 19 is formed between the protruding ring 18 and the pressing post 15. The fixing post 13 is provided with an installation groove 20, and the fixing claw 16 is hinged in the installation groove 20. The fixing claw 16 is provided with a pressing part 21, which is located in the groove 19. A spring 22 is sleeved on one end of the pressing post 15, and the two ends of the spring 22 are respectively connected to the bottom end of the protruding ring 18 and the sliding groove 17. The bottom of the sliding groove 17 is provided with a bottom groove 23. The fixing post 13 is provided with an external thread 24, and the fixing nut 14 is threadedly connected to the fixing post 13. The fixing nut 14 is provided with a handle 25 to facilitate the turning of the fixing nut 14.

[0032] When using the fastener 4, to lock the retaining ring 3, first press the compression pin 15, pressing one end of the compression pin 15 into the bottom groove 23. At this time, the compression pin 15 will press the pressing part 21 of the retaining claw 16, causing the retaining claw 16 to rotate and retract into the mounting groove 20, allowing the retaining pin 13 to pass through the retaining hole 12. Then release the compression pin 15, and the compression pin 15 will return to its original position under the elastic action of the spring 22. At this time, the compression pin 15 will drive the retaining claw 16 to rotate, and one end of the retaining pin 13 will extend... Remove the mounting slot 20, then rotate the fixing nut 14. Under the synergistic action of the fixing nut 14 and the fixing claw 16, the two fixing rings 3 are fixed. When disassembling the fixing part 4, first press the squeezing column 15 to make the fixing claw 16 rotate and retract into the mounting slot 20. Then pull the pull ring 26 to pull the fixing part 4 out of the fixing hole 12. The setting of the fixing part 4 makes it possible to lock without auxiliary tools, which is simple to operate, thereby reducing the complexity of connection, increasing construction efficiency, and facilitating the installation and disassembly of the duct assembly.
