[0017] Figure 3 for Figure 1 Exploded view;

[0018] Figure 4 for Figure 1 A schematic diagram of the installation status. Detailed Implementation

[0019] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0020] like Figures 1 to 4 As shown, the docking assembly of this fabric-insulated duct includes a clamping member 2 and a pressing rod 3.

[0021] The clamping member 2 consists of symmetrically arranged elastic arms 4 and abutment sections 5 for connecting the elastic arms 4. One end of the elastic arm 4 is connected through the abutment section 5, and the other end is brought into contact by force.

[0022] The pressing rod 3 cooperates with the clamping member 2. One end of the pressing rod 3 is hinged to the elastic arm 4 through the hinge rod 6. Pressing the symmetrical pressing rod 3 keeps the end of the elastic arm 4 away from the abutment section 5 open.

[0023] The elastic arm 4 has an overall elliptical structure, allowing it to open under force. The elastic arm 4 consists of a contact section 7, a deformation section 8, an elastic section 9, and a load-bearing section 10. A clamping area 11 is formed between the contact sections 7. A covering material is provided on the duct to prevent air leakage, and the clamping area 11 holds the covering material. Furthermore, a steel wire 12 is present in the duct, contacting the abutment section 5, thereby allowing the docking assembly 1 to be clamped between the two duct sections.

[0024] The elastic section 9 is provided with a first punching hole 13, and a hinge section 19 is arranged in the first punching hole 13. The hinge section 19 is formed with a hinge area 14 in the middle, and the hinge rod 6 is arranged in the hinge area 14. One end of the pressing rod 3 is provided with symmetrical hinge parts 15 arranged on both sides of the elastic section 9. The hinge parts 15 are matched with the hinge section 19 to arrange the hinge rod 6. Through the cooperation of the hinge parts 15 and the hinge section 19, when the pressing rod 3 is pressed again, the elastic arm 4 can be driven to open, so that the contact section 7 is separated.

[0025] The elastic section 9 is further provided with a second punching hole 16, and a support section 17 is arranged in the second punching hole 16. The support section 17 is in contact with the middle of the pressing rod 3. The inner wall of the bearing section 10 is provided with multiple reinforcing ribs 18. When pressing, the middle of the pressing rod 3 is abutted on the support section 17, and the bearing section 10 is provided with the reinforcing ribs 18, so that the bearing section 10 can be prevented from being deformed under stress.

[0026] In use, only the two ends of the pressing rod 3 need to be pressed, so that the other end drives the hinge part 15 and the deformation section 8 and the contact section 7 to move to both sides, so that the clamping area 11 is opened, and the two air pipes are clamped.

[0027] The above only describes the preferred embodiments of the present application, and is not used to limit the present application. Any modification, equivalent replacement and improvement within the spirit and principle of the present application shall be included in the protection scope of the present application.
