In this way, the air duct can be connected. In order to improve the tightness of the air duct connection, multi-point penetration locking is required. There are many locking points, and the assembly locking speed is slow, which is inconvenient for the assembly and use of the air duct. Utility Model Content

[0003] Therefore, the purpose of the utility model is to provide an assembled structure of a composite air duct. By cooperating with the provided composite air duct assembly and the assembled locking assembly, when in use, the air duct can be aligned and pressed, and the air duct can be locked at multiple points by the pressing force, and it will not separate after locking, thereby greatly improving the air duct assembly efficiency.

[0004] To solve the above technical problems, according to one aspect of the present invention, the present invention provides the following technical solution: an assembled structure of a composite air duct, comprising:

[0005] A composite air duct assembly, the composite air duct assembly comprising a first air duct, a second air duct arranged on the side of the first air duct, a first square plate connected to the first air duct, and a second square plate connected to the second air duct;

[0006] An assembly locking component includes a notch opened on the surface of the second square plate, a rotating shaft connected to the inner side of the notch, a connecting rod connected to the rotating shaft, a metal hook connected to the top end of the connecting rod, a flat plate connected to the bottom end of the connecting rod, a rectangular hole opened on the inner wall of the notch, a spring connected to the rectangular hole, a limiting inclined plate connected to the top end of the spring, and an arc surface opened on the top surface of the limiting inclined plate.

[0007] As a preferred solution of the assembled structure of a composite air duct described in the utility model, the side end of the limiting inclined plate and the rectangular hole are mutually fitted, and the end of the limiting inclined plate moves in the rectangular hole.

[0008] As a preferred solution of the assembled structure of a composite air duct described in the utility model, there are two limiting inclined plates, arc surfaces and rectangular holes, and the two limiting inclined plates, arc surfaces and rectangular holes are symmetrically arranged at the midline position of the notch groove.

[0009] As a preferred solution of the assembled structure of the composite air duct described in the utility model, the four frame positions of the second square plate are respectively provided with notch grooves of the same structure;

[0010] Each notch groove is provided with a corresponding rotating shaft, a metal hook, a flat plate, a limiting inclined plate, an arc surface, a rectangular hole, a spring and a connecting rod.

[0011] As a preferred solution of the assembled structure of a composite air duct described in the utility model, it also includes an adjustment component, which includes a rectangular long plate fixed on the bottom surface of the metal hook, a rectangular long slot opened on the top surface of the connecting rod, and a threaded hole opened on the surface of the connecting rod.

[0013] Wherein, the end of the threaded rod abuts against the rectangular long plate.

[0014] Compared with the prior art, the advantages of the utility model are:

[0015] 1. The utility model cooperates with the composite air duct component and the assembly locking component to achieve multi-point locking of the air duct by aligning and pressing the air duct during use, and the air duct will not separate after locking, which greatly improves the air duct assembly efficiency.

[0016] 2. Based on the beneficial effect 1, the position of the metal hook can be freely adjusted through the setting adjustment component, which is convenient for matching and locking square plates of different thicknesses, thereby improving the applicability of air duct assembly.

[0017] During specific use, the user connects the first air duct and the second air duct with each other, and makes the first square plate and the second square plate fit together, and applies extrusion force. At this time, the first square plate presses the flat plate downward, and the flat plate is squeezed and rotates downward through the rotating shaft. At this time, the flat plate can drive the metal hook to flip until the flat plate squeezes the curved surface. When the curved surface is subjected to extrusion force, the curved surface and the limiting inclined plate move into the rectangular hole. When the flat plate continues to be pressed downward and disengaged from the curved surface, the spring pushes the limiting inclined plate to return to its original position, and the limiting inclined plate blocks the flat plate. At this time, the metal hook is pressed on the surface of the first square plate, locking the first square plate and preventing it from disengaging, which is convenient for assembly and use.

[0028] The utility model provides an assembled structure of a composite air duct. By cooperating with the provided composite air duct component and the assembled locking component, when in use, the air duct can be aligned and pressed, and the air duct can be locked at multiple points by the force of pressing, and the air duct will not separate after locking, thus greatly improving the assembly efficiency of the air duct. Example

[0029] Figure 1 , Figure 2 and Figure 3 The figure shows the overall structure of an assembled structure of a composite air duct according to the utility model. Figure 1 , Figure 2 and Figure 3 The main structure of this embodiment includes: a composite air duct assembly and an assembly locking assembly.

[0030] The composite air duct assembly is used in conjunction with the assembly locking assembly. Specifically, the composite air duct assembly includes a first air duct 11, a second air duct 12 arranged on the side of the first air duct 11, a first square plate 13 connected to the first air duct 11, and a second square plate 14 connected to the second air duct 12;

[0031] During specific use, the assembly locking assembly is installed and used based on the first air duct 11 , the second air duct 12 , the first square plate 13 and the second square plate 14 .

[0032] The assembly locking assembly is used for locking at multiple points at the same time, without the need to screw bolts at multiple points, thereby improving the locking efficiency. Specifically, the assembly locking assembly includes a notch groove 21 provided on the surface of the second square plate 14, a rotating shaft 22 connected to the inner side of the notch groove 21, a connecting rod 29 connected to the rotating shaft 22, a metal hook 23 connected to the top of the connecting rod 29, a flat plate 24 connected to the bottom end of the connecting rod 29, a rectangular hole 27 provided on the inner side wall of the notch groove 21, a spring 28 connected to the rectangular hole 27, a limiting inclined plate 25 connected to the top of the spring 28, and an arc surface 26 provided on the top surface of the limiting inclined plate 25;

[0033] During specific use, the user docks the first air duct 11 and the second air duct 12 with each other, and makes the first square plate 13 and the second square plate 14 fit together and apply an extrusion force. At this time, the first square plate 13 presses the flat plate 24 downward, and the flat plate 24 is squeezed and rotates downward through the rotating shaft 22. At this time, the flat plate 24 can drive the metal hook 23 to flip until the flat plate 24 squeezes the curved surface 26. When the curved surface 26 is subjected to the extrusion force, the curved surface 26 and the limiting inclined plate 25 move into the rectangular hole 27. When the flat plate 24 continues to be pressed downward and disengages from the curved surface 26, the spring 28 pushes the limiting inclined plate 25 to return to its original position, and the limiting inclined plate 25 blocks the flat plate 24. At this time, the metal hook 23 is pressed on the surface of the first square plate 13 to lock the first square plate 13 and will not disengage, which is convenient for assembly and use. Example

[0034] Please refer to Figure 4 , through the setting adjustment component, the position of the metal hook 23 can be freely adjusted, so that it is convenient to fit and lock the square plates of different thicknesses, thereby improving the applicability of the air duct assembly;

[0036] During specific use, the rectangular long plate 31 is inserted into the rectangular long slot 32, and a threaded rod passes through the threaded hole 33, and the end of the threaded rod abuts against the rectangular long plate 31. In this way, the user can adjust the position of the metal hook 23 by pulling the metal hook 23. When it is adjusted to the required position, the user can turn the threaded rod to lock the rectangular long plate 31. This is suitable for locking square plates of different thicknesses, thereby improving applicability.
