[0002] Fabric ducts are flexible duct systems made of special fiber fabrics used for air transport and distribution. They are also known as fiber fabric ducts or cloth ducts. Fabric ducts are widely used in ventilation, air conditioning and air purification systems in industrial plants, commercial buildings, stadiums, exhibition halls, airports, subways and other places.

[0003] In practical ventilation or air conditioning systems, the length of a single fabric duct is often insufficient to meet the distance requirements from the air handling unit to each air supply point. By connecting multiple ducts, the required length can be flexibly combined according to the specific engineering layout and design requirements to deliver air to rooms, areas or air outlets in different locations within the building, ensuring that the ventilation system can cover the entire space requiring air conditioning.

[0004] In the existing technology, when using fabric ducts for installation and connection, bolts and other parts are required to connect and fix the fabric ducts, which is a complicated and time-consuming process, thus reducing the efficiency of fabric duct installation and fixing. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a magnetic quick-installation fabric duct connection structure, which aims to solve the problem that the installation process of the existing fabric duct connection structure is complicated and time-consuming, resulting in reduced installation and fixing efficiency.

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

[0025] Reference Figures 1-3 This utility model provides an embodiment of a magnetic quick-installation fabric duct connection structure, including a first fixing block 1, a first handle 2 rotatably connected to the inner wall of the first fixing block 1, a first turntable 3 fixedly disposed on the lower surface of the first handle 2, a first engaging claw 4 rotatably connected to the outer wall of the first turntable 3, a second turntable 5 rotatably connected to the outer wall of the first engaging claw 4, a second fixing block 6 rotatably connected to the inner wall of the second turntable 5, a spring 7 fixedly connected to the inner wall of the second fixing block 6, and a third fixing block 7 fixedly connected to the outer wall of the spring 7. Block 8, the lower surface of the third fixing block 8 is fixedly connected to the upper surface of the second turntable 5, the outer wall of the second turntable 5 is rotatably connected to the second engaging claw 9, the outer wall of the second engaging claw 9 is slidably connected to the inner wall of the first turntable 3, the lower surface of the first fixing block 1 is provided with a magnetic quick-installation assembly, the magnetic quick-installation assembly includes a connecting ring 10, the upper surface of the connecting ring 10 is fixedly connected to the lower surface of the first fixing block 1, the inner wall of the connecting ring 10 is fixedly connected to the bag air duct body 11, and the inner wall of the connecting ring 10 is fixedly connected to the magnetic element 12;

[0026] Specifically, rotating the first handle 2 drives the first turntable 3 to rotate. The rotation of the first turntable 3 drives the first engaging claw 4 to rotate and pulls the second turntable 5 to rotate. The second fixing block 6 can limit the rotation of the second turntable 5, thereby achieving the effect of maintaining its stable rotation. At this time, the first engaging claw 4 will disengage from the second turntable 5. When the second turntable 5 rotates, it will pull the spring 7 to cause it to undergo elastic deformation, thereby generating a reaction force, which makes it easy to pull the second turntable 5 back to its original position for easy use next time. When the second turntable 5 rotates, it will drive the second engaging claw 9 to rotate. At this time, the second engaging claw 9 will disengage from the first turntable 3, causing the second fixing block 6 and the first fixing block 1 to disengage, thereby achieving the effect of quick disassembly and installation of the second fixing block 6 and the first fixing block 1. Through the magnetic element 12 fixed to the inner wall of the connecting ring 10 on the outer wall of the fabric duct body 11, the magnetic connection of the fabric duct can be realized, thereby achieving the effect of quick docking of the fabric duct body 11.

[0027] Reference Figure 1 and Figure 4 A fixed shell 13 is fixedly connected to the lower surface of the bag duct body 11. A second handle 14 is rotatably connected to the inner wall of the fixed shell 13. A rotating plate 15 is fixedly provided on the outer wall of the second handle 14. A first transmission plate 16 is rotatably connected to the outer wall of the rotating plate 15. A sliding plate 17 is rotatably connected to the outer wall of the first transmission plate 16. A slide rail 18 is slidably connected to the inner wall of the sliding plate 17. The outer wall of the slide rail 18 is fixedly connected to the inner wall of the fixed shell 13.

[0028] Specifically, by rotating the second throttle 14, the rotating plate 15 is driven to rotate. The fixed shell 13 can limit the rotation of the second throttle 14, thereby achieving the effect of maintaining its stable rotation. The rotation of the rotating plate 15 drives the first transmission plate 16 to rotate. The rotation of the first transmission plate 16 drives the sliding plate 17 to slide vertically. The slide rail 18 will limit the sliding of the sliding plate 17, thereby achieving the effect of maintaining its stable sliding.

[0029] Reference Figure 1 and Figure 4 The inner wall of the sliding plate 17 is rotatably connected to the second transmission plate 19, the inner wall of the first transmission plate 16 is rotatably connected to the push rod 20, the outer wall of the push rod 20 is slidably connected to the inner wall of the bag duct body 11, the outer wall of the push rod 20 is provided with a protrusion, the inner wall of the second transmission plate 19 is rotatably connected to the outer wall of the protrusion, and the outer wall of the push rod 20 is fixedly connected to the sealing ring 21, the outer wall of the sealing ring 21 is slidably connected to the inner wall of the bag duct body 11;

[0030] Specifically, the sliding plate 17 can drive the first transmission plate 16, thereby pushing the second transmission plate 19 to rotate. At this time, the second transmission plate 19 will cooperate with the first transmission plate 16 to make the push rod 20 slide horizontally. The push rod 20 will drive the sealing ring 21 to slide, so that the sealing ring 21 covers the gap of the bag air duct connection, thereby achieving the effect of sealing the bag air duct.

[0031] Working principle: When this structure is needed, by connecting the fabric duct body 11 to another fabric duct, the connecting ring 10 fixed to the outer wall of the fabric duct body 11 will drive the magnetic element 12 to approach. The magnetic element 12 will then attract the fabric duct, achieving a quick connection and installation. At this time, the second engaging claw 9 and the first engaging claw 4 will slide on the outer wall of the first and second turntables 3 and 5, causing them to rotate and engage, thus achieving a secondary connection and fixation of the fabric duct, making the connection more stable. The second turntable 5 will then pull the spring 7, causing it to elastically deform and generate a reaction force, facilitating the return of the second turntable 5 to its original position. This allows for cyclical use of the structure. When disassembly is required, rotating the first handle 2 will detach the second fixing block 6 from the first fixing block 1. The mechanism engages to achieve quick disassembly. Then, rotating the second handle 14 rotates the rotating plate 15, causing the first transmission plate 16 to rotate. The rotation of the first transmission plate 16 causes the sliding plate 17 to slide against the outer wall of the slide rail 18. The slide rail 18 limits the sliding of the sliding plate 17, maintaining stable sliding. The sliding plate 17 then drives the second transmission plate 19 to rotate. The second transmission plate 19, in conjunction with the first transmission plate 16, drives the push rod 20 to slide horizontally, causing the sealing ring 21 to slide to the connection point of the fabric duct, thus covering the gap and reducing air loss, achieving a sealing effect on the fabric duct. This structure, on the one hand, enables quick connection and installation of the fabric duct through magnetic attraction and snap-fit; on the other hand, it allows the sealing ring 21 to cover the connection point, thereby sealing the fabric duct and reducing air transport loss.

[0032] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
