For those skilled in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances.

[0029] Please refer to Figures 1-2 An energy-saving and environment-friendly composite air pipe, comprising two frames 1, the two frames 1 are square and slidingly clamped with four sets of fixing assemblies 2, and the four sets of fixing assemblies 2 are fixedly connected with four sets of composite boards 3 which are annularly abutted with each other;

[0030] One set of fixing assembly 2 comprises a right angle rod 21, two square blocks 22 and two springs 23, the two square blocks 22 are fixed on the two sides of the right angle rod 21 respectively, four sliding grooves 13 are formed at the four corner sides of the frame 1 close to the fixing assembly 2, the spring 23 and the square block 22 are arranged in the sliding groove 13, and the spring 23 can elastically act on the end of the square block 22 in the direction of the sliding groove 13 on one side of the composite board 3;

[0031] Four straight angle poles 21 are used to clamp and fix the outer edge of the composite plate 3.

[0032] The four sliding grooves 13 are all directed to the center of the frame 1.

[0033] The frame 1 is provided with several adjusting assemblies 4 for locking and fixing the assembly 2.

[0034] In this embodiment, several mounting holes 12 are formed on the frame 1 for connecting multiple composite air ducts.

[0035] It should be noted that these mounting holes 12 are provided to facilitate the quick and stable connection of multiple energy-saving and environment-friendly composite air ducts during the actual construction of the ventilation system, so as to form a complete and efficient ventilation duct network to meet the ventilation needs of different scales and layouts.

[0036] It should be further noted that by setting appropriate distances between multiple composite air ducts and then assembling them through the mounting holes 12, the close connection between the composite plate 3 and the frame 1 can be ensured, and the size of the composite plate 3 needs to be designed reasonably so that the annular structure composed of the composite plate 3 is tightly connected with the limiting protrusions 11 and does not leak air. Even if there is a gap between the composite plate 3 and the frame 1, it will not affect the air tightness of the air duct.

[0037] In this embodiment, limiting protrusions 11 are formed on the inner sides of the opposite faces of the two frames 1, the outer side faces of the limiting protrusions 11 abut against the composite plate 3, and sealing rings are arranged on the contact surfaces between the limiting protrusions 11 and the composite plate 3.

[0038] It should be noted that the limiting protrusions 11 serve to position the composite plate 3, ensuring that the composite plate 3 can be accurately placed at the specified position in the frame 1 during installation, preventing it from shifting. The sealing rings can effectively enhance the sealing between the composite plate 3 and the frame 1, avoiding air leakage and improving the efficiency of the ventilation system. At the same time, it also reduces energy loss caused by air leakage, in line with the concept of energy saving and environmental protection.

[0039] In this embodiment, gaskets 24 are arranged on the contact surfaces between the straight angle poles 21 and the composite plate 3.

[0040] It should be noted that the gaskets 24 have multiple functions. On the one hand, they can increase the friction between the straight angle poles 21 and the composite plate 3, making the composite plate 3 more firmly fixed on the frame 1. On the other hand, the gaskets 24 can serve as a buffer to reduce direct friction and collision between the straight angle poles 21 and the composite plate 3 during the operation of the air duct, avoiding damage to the composite plate 3 and thus prolonging the service life of the air duct.

[0041] In this embodiment, the adjusting assembly 4 includes a fixed block 41 and a bolt 42, the fixed block 41 is fixed with the frame 1, and the bolt 42 is threaded through the fixed block 41 and one end is in abutment with the right-angle rod 21.

[0042] It should be noted that the fixed block 41 provides a stable mounting base for the bolt 42, and by screwing or unscrewing the bolt 42 on the fixed block 41, the abutment degree of the bolt 42 and the right-angle rod 21 can be accurately adjusted, thereby realizing the locking or loosening operation of the fixing assembly 2, and facilitating the fixing or dismounting of the composite board 3 according to actual needs.

[0043] In this embodiment, each right-angle rod 21 is provided with at least two groups of adjusting assemblies 4 vertically acting on different sides of the right-angle rod 21 on one side frame 1.

[0044] It should be noted that at least two groups of adjusting assemblies 4 are provided to fix and adjust the right-angle rod 21 from different directions, to ensure the stability of the position of the right-angle rod 21 on the frame 1, and to prevent the right-angle rod 21 from shaking or deviating, thereby ensuring the uniform and reliable clamping and fixing effect of the composite board 3 and improving the stability of the entire air pipe structure.

[0045] In this embodiment, the end of the bolt 42 in abutment with the right-angle rod 21 is rounded, and the bolt 42 is in sliding abutment with the right-angle rod 21.

[0046] It should be noted that the rounded end of the bolt 42 can reduce stress concentration when in contact with the right-angle rod 21 during adjustment, and avoid damaging the right-angle rod 21. The sliding abutment mode makes the friction between the bolt 42 and the right-angle rod 21 smaller when adjusting the position of the bolt 42, and the operation is more smooth, while also reducing wear caused by friction and prolonging the service life of the adjusting assembly 4.

[0047] In summary: the energy-saving and environment-friendly composite air pipe, by setting the sliding clamping fixing assembly 2, using the spring 23 to elastically act on the square block 22, the right-angle rod 21 can be flexibly adjusted in position, thereby adapting to composite boards 3 of different thicknesses, solving the problem that traditional air pipes are difficult to adapt to composite boards 3 of different thicknesses due to fixed structure, and improving the applicability of the air pipe in diversified scenarios.

[0048] The energy-saving and environment-friendly composite air pipe, by setting the adjusting assembly 4, using the bolt 42 to slide and abut with the right-angle rod 21 to lock the fixing assembly 2, avoids the situation that the traditional bolt 42 directly connected mode penetrates the composite board 3 when dismounting, realizes the purpose of convenient dismounting without damaging the composite board 3, ensures the overall performance and service life of the air pipe, and meets the energy-saving and environment-friendly requirements.

[0049] Working principle: when installing the composite plate 3, first, four groups of composite plates 3 are placed in abutment with each other between two frames 1. Since the sliding clamps on the frame 1 are provided with four groups of fixing assemblies 2, the right-angle rods 21 in each group of fixing assemblies 2 are elastically acted on the end of the square block 22 in the direction of the sliding slot 13 on one side of the composite plate 3 by the spring 23, so that the right-angle rod 21 has a certain activity space. At this time, the fixing assembly 2 can be adjusted by the adjusting assembly 4 according to the actual thickness of the composite plate 3. Specifically, by rotating the bolt 42, the bolt 42 is screwed into the fixed block 41, one end of the bolt 42 is in sliding abutment with the right-angle rod 21, and the right-angle rod 21 is gradually pushed towards the center of the frame 1, and the four right-angle rods 21 jointly clamp and fix the outer edge of the composite plate 3. In the clamping process, the gasket 24 on the contact surface between the right-angle rod 21 and the composite plate 3 plays a role in buffering and increasing friction, so as to ensure that the composite plate 3 is firmly and stably fixed.

[0050] When it is necessary to disassemble the composite plate 3, the bolt 42 is only needed to be reversely rotated, so that the bolt 42 is screwed out of the fixed block 41, the abutting force of the bolt 42 on the right-angle rod 21 is reduced, the right-angle rod 21 moves outward along the direction of the sliding slot 13 under the elastic restoring force of the spring 23, and the clamping of the composite plate 3 is released, so that the composite plate 3 can be conveniently taken out of the frame 1, and the whole disassembly process will not cause damage to the composite plate 3.

[0051] Meanwhile, the limiting protrusion 11 on the frame 1 plays a role in positioning the composite plate 3, and the sealing ring on the contact surface between the limiting protrusion 11 and the composite plate 3 ensures the sealing property between the composite plate 3 and the frame 1. The mounting hole 12 on the frame 1 is used to realize quick and stable connection through a suitable connecting piece when it is necessary to connect multiple composite air ducts, so as to construct a complete ventilation system. This design makes the energy-saving and environment-friendly composite air duct be able to adapt to composite plates 3 of different thicknesses, is convenient to disassemble and does not damage the composite plate 3, improves the applicability of the air duct in diversified scenes, ensures the overall performance and service life of the air duct, and meets the energy-saving and environment-friendly requirements.

[0052] Although the embodiments of the utility model have been shown and described, it can be understood by those skilled in the art that various changes, modifications, replacements and variations can be made to the embodiments without departing from the principles and spirits of the utility model, and the scope of the utility model is defined by the appended claims and their equivalents.
