DETAILED DESCRIPTION

[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0022] like Figure 1 - Figure 6As shown, the utility model provides a technical solution: a connection structure of an air duct cloth, comprising a first cloth tube 1, one end of the first cloth tube 1 is fixedly connected with a first connection end 11, and the end of the first connection end 11 away from the first cloth tube 1 is attached with a second connection end 12, the end of the second connection end 12 away from the first connection end 11 is fixedly connected with a second cloth tube 13, and a clamping groove 14 is provided inside the end of the second connection end 12 close to the first connection end 11, a clamping component is fixedly connected to the side of the first connection end 11 close to the second connection end 12, and a latch component is fixedly connected to the inner side of the end of the second connection end 12 close to the first connection end 11, a pushing component is arranged on the outer side of the end of the first connection end 11 close to the first cloth tube 1, and a supporting component is fixedly connected to the outer side of the pushing component, the pushing component is inserted into the inner side of one end of the supporting component and is fixedly connected with a limiting component, when splicing two adjacent sets of air duct cloths, the first connection component is first connected. The end 11 drives the locking component to be inserted into the second connection end 12. During the insertion process, the first connection end 11 squeezes the latch component installed on the second connection end 12. After being squeezed, the latch component is inserted into the slot 14, and then the first connection end 11 is rotated. The rotation of the first connection end 11 drives the locking component to be further inserted into the slot 14 for locking. When the first connection end 11 is rotated to a suitable position, the latch component pops out and is inserted into the first connection end 11 for fixation. When it is subsequently removed, the pushing component can be toggled with the assistance of the supporting component. The pushing component moves with the assistance of the limiting component to squeeze the latch component, thereby pushing the latch component out of the first connection end 11. Then, the first connection end 11 is rotated to drive the locking component to be pulled out of the slot 14. When the connecting structure is used to splice two adjacent groups of air duct cloths, the splicing method is simple and convenient, the splicing stability is strong, and it can be quickly removed later.

[0023] like Figure 4 As shown, the positioning assembly includes a first plug rod 2 fixedly connected to the first connection end 11 near the second connection end 12, and the end of the first plug rod 2 away from the first connection end 11 is fixedly connected to the second plug rod 21, and the ends of the first plug rod 2 and the second plug rod 21 away from the first connection end 11 are inserted into the slot 14. By inserting the first plug rod 2 and the second plug rod 21 into the slot 14, the first connection end 11 and the second connection end 12 are pre-positioned and restricted.

[0024] like Figure 6 As shown, the latch assembly includes a plug board 3 inserted inside one end of the second connection end 12 close to the first connection end 11, and one end of the plug board 3 inserted in the second connection end 12 is fixedly connected to a first spring 31, and one end of the first spring 31 away from the plug board 3 is fixedly connected to the second connection end 12, and the elastic potential energy of the first spring 31 is used to facilitate pushing the plug board 3, so that the plug board 3 is inserted into the first connection end 11 and fixed in place.

[0025] like Figure 6 As shown, the pushing assembly includes a first push plate 4 arranged on the outer side of one end of the first tube cloth 1 near the first connecting end 11, and a second push plate 41 is fixedly connected to the inner side of the first push plate 4, and an end of the second push plate 41 away from the first push plate 4 is inserted into the first connecting end 11, and a second spring 42 is fixedly connected to one side of the first push plate 4, which pushes the first push plate 4. After the first push plate 4 is pushed, it drives the second push plate 41 to move and stretch the second spring 42. After the second push plate 41 moves, it pushes the plug plate 3 to push the plug plate 3 out of the first connecting end 11, so as to facilitate the release of the card position restriction between the first connecting end 11 and the second connecting end 12.

[0026] like Figure 1 As shown, the support assembly includes a positioning ring 5 fixedly connected to one end of the second spring 42 away from the first push plate 4, and a tooth plate 51 is fixedly connected to the outer side of the positioning ring 5. By using the tooth plate 51 installed on the outer side of the positioning ring 5, the user can more conveniently rotate the first connecting end 11 through the tooth plate 51.

[0027] like Figure 6 As shown, the limiting assembly includes a sleeve 6 inserted inside the second spring 42, and the end of the sleeve 6 close to the positioning ring 5 is fixedly connected to the sleeve 6, and a positioning rod 61 is inserted inside the end of the sleeve 6 away from the positioning ring 5, and the end of the positioning rod 61 away from the sleeve 6 is fixedly connected to the first push plate 4, and the movement of the first push plate 4 is limited by the extension and retraction of the sleeve 6 and the positioning rod 61.

[0028] Working principle: When splicing two adjacent groups of air duct cloths, first drive the first connecting end 11 to insert the first plug rod 2 and the second plug rod 21 into the card slot 14. During the insertion process of the first plug rod 2 and the second plug rod 21, the first connecting end 11 squeezes the plug plate 3, and the plug plate 3 is squeezed and inserted into the second connecting end 12 to compress the first spring 31. When the first connecting end 11 and the second connecting end 12 are fitted, the first connecting end 11 is rotated to allow the first connecting end 11 to drive the second plug rod 21 to continue to be inserted into the card slot 14 for limiting. When the first connecting end 11 is rotated to a suitable position, the first spring 31 pushes the plug plate 3 in the opposite direction, allowing the plug plate 3 to The pop-up plug is inserted into the first connecting end 11 to lock the first connecting end 11 and the second connecting end 12 to complete the splicing. When it is subsequently dismantled, the first push plate 4 is pushed with the assistance of the positioning ring 5. After the first push plate 4 is pushed, it drives the second push plate 41 to move and stretch the second spring 42 under the restriction of the sleeve 6 and the positioning rod 61. After the second push plate 41 moves, it pushes the plug plate 3. After the plug plate 3 is pushed out of the first connecting end 11, the first tube cloth 1 is driven to rotate through the toothed plate 51. The rotation of the first connecting end 11 is used to rotate the first plug rod 2 and the second plug rod 21 to a suitable log, and then the first connecting end 11 is pulled to drive the first plug rod 2 and the second plug rod 21 to pull out of the card slot 14.

[0029] The above embodiments are only used to illustrate the technical solution of the present invention, but not to limit it.
