Description

Technical Field

[0001] This utility model relates to the field of ventilation duct technology, and in particular to an assembled ventilation duct. Background Technology

[0002] Currently, mainstream ventilation ducts are primarily made of metal, commonly round / rectangular ducts made of galvanized steel, stainless steel, and aluminum. These ducts are high in strength and pressure resistance, and are widely used in building air conditioning systems, industrial exhaust systems, and other applications. There are also insulated ducts made of composite materials such as phenolic foam and polyurethane, which also provide thermal insulation and are suitable for environments requiring temperature control. Flexible hoses are mostly made of PVC-coated fabric or rubber, offering good elasticity and flexibility, and are often used for end-of-line connections or complex wiring.

[0003] Patent CN219606418U discloses an assembled ventilation duct, comprising a ventilation duct body; a fixed base fixed to the bottom of the ventilation duct body; a support plate fixed to the bottom of the fixed base; a connecting plate on one side wall of the ventilation duct body; a friction sealing plate fixed to the connecting plate near the side wall of the ventilation duct body; and multiple sets of friction sealing plates fixed to the connecting plate near the side wall of the ventilation duct body. During operation, this achieves the effect of sealing the joints of multiple ventilation duct bodies. The integrated device combines the ventilation duct body with the fixed sealing device, thereby reducing the welding steps required for operators to operate the welding equipment, reducing the risk of corrosion of the welded joints by laboratory gases, and preventing gas leaks caused by airflow passing through multiple ventilation duct bodies being discharged to the outside through weld breaks.

[0004] The inventors have discovered at least the following problems in the prior art:

[0005] The existing modular ventilation ducts mentioned above occupy space during transportation due to their integrated structure, which increases transportation costs. Furthermore, they lack modularity because they are constructed by splicing two types of ventilation ducts together.

[0006] In addition, although it does not require welding due to its plug-in connection, there will still be gaps at the joints between pipes during the connection process, which can lead to leakage.

[0007] Therefore, this solution provides an assembled ventilation duct to address the aforementioned problems. Utility Model Content

[0008] The purpose of this invention is to provide an assembled ventilation duct to solve the problems of insufficient modules leading to high transportation costs and gaps still appearing at the joints in the existing technology.

[0009] To solve the above-mentioned technical problems, the basic technical solution proposed by this utility model is as follows:

[0010] An assembled ventilation duct includes two centrally symmetrical modular mechanisms. Each modular mechanism includes a base plate and two side plates on either side of the base plate. A mating plate is fixedly connected to the inner side of the side plate. A female connection mechanism and a male connection mechanism are respectively provided at both ends of the base plate, side plate one, and side plate two. The female connection mechanism includes a female plate and a deformable protrusion in the middle of the female plate. The male connection mechanism includes a receiving plate, a male plate, and a recess in the middle of the male plate, the recess fitting the inner side of the deformable protrusion. The mating plate has evenly distributed mounting holes, and bolts are installed inside the mounting holes.

[0011] Preferably, both sides of the base plate are fixedly connected to curved sections, and the base plate is fixedly connected to side plate one and side plate two through the curved sections.

[0012] Preferably, one end of the bent portion is fixedly connected to a connecting portion, the connecting portion is fixedly connected to both ends of the female connector plate, and one side of the female connector plate is fixedly connected to one end of the base plate.

[0013] Preferably, the end of the female connector plate away from the base plate is a compensation part one, and the receiving plate is fixedly connected to the inner side of one end of the base plate.

[0014] Preferably, the side of the receiving plate away from the receiving plate is the compensation part two.

[0015] Preferably, the top ends of the second side plate and the first side plate are provided with evenly distributed notches, which fit around the periphery of the mating plate.

[0016] Preferably, a sealing gasket is provided on the outside of the bolt, and the sealing gasket fits into the inside of the notch.

[0017] The beneficial effects of this utility model are:

[0018] I. This utility model divides the ventilation duct into independent modular structures that are symmetrical at the top and bottom. These modular structures can be stacked during transportation, reducing space occupation and significantly lowering transportation costs. At the same time, the modular structure facilitates production, storage, and subsequent maintenance.

[0019] Second, this utility model achieves a tight connection by applying pressure to the female connector mechanism and the male connector mechanism through deformation caused by the deformation of the female connector protrusion and the male connector recess. Combined with the synergistic effect of compensation part one and compensation part two, it ensures that there is no gap at the splice. In addition, the sealing gasket set in the notch is further embedded in the fixing hole of the docking plate to form a multi-seal structure to prevent gas leakage. Attached Figure Description

[0031] Please refer to the following. Figures 1 to 6 As shown, the technical solutions in the embodiments of this utility model are clearly and completely described. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of this utility model.

[0032] It should be noted that, in the embodiments of this utility model, the directions shown in the accompanying drawings shall prevail, such as front and back. Figure 1 For the sake of accuracy, the specific details should be as follows: Figure 1 The left side is the front. Figure 1 The right side is the rear; at the same time, as Figure 2 As shown, the horizontal direction is roughly defined as left and right, and the vertical direction is defined as up and down. If a specific orientation changes, the directional indication will also change accordingly.

[0033] This utility model provides an assembled ventilation duct, including two modular mechanisms 1 that are symmetrical about the top and bottom. The modular mechanism 1 includes a base plate 11 and side plates 12 and 13 on both sides of the base plate 11. A connecting plate 15 is fixedly connected to the inner side of the side plate 13.

[0034] Both ends of the base plate 11, side plate 12 and side plate 2 are respectively provided with a female connection mechanism 2 and a male connection mechanism 3;

[0035] The female connector mechanism 2 includes a female connector plate 21 and a deformable protrusion 22 opened in the middle of the female connector plate 21;

[0036] The male connection mechanism 3 includes a receiving plate 31 and a male connection plate 32, and a recess 33 opened in the middle of the male connection plate 32. The recess 33 fits the inner side of the deformable protrusion 22.

[0037] The mating plate 15 has evenly distributed mounting holes 16, and bolts 5 are installed inside the mounting holes 16;

[0038] The male connection mechanism 3 at the same end of the base plate 11, side plate 12 and side plate 2 13 is fixedly connected by the receiving plate 31, while the other end is directly fixedly connected to the female connection plate 21. The base plate 11, side plate 12, side plate 2 13, female connection plate 21, receiving plate 31 and bending part 17 are an integrated structure.

[0039] After the deformable protrusion 22 and the recess 33 are fitted together, pressure can be applied from the outside of the deformable protrusion 22 inward using pliers. Figure 5 The dashed arrow in the middle applies force, thus causing deformation.

[0040] In a further embodiment, both sides of the base plate 11 are fixedly connected with bending portions 17, and the base plate 11 is fixedly connected to side plate one 12 and side plate two 13 through the bending portions 17.

[0041] In this embodiment, the curved portion 17 has a triangular groove pre-cut on its inner side, so it can be bent, and can only be bent at ninety degrees.

[0042] In a further embodiment, one end of the bent portion 17 is fixedly connected to a connecting portion 18, which is fixedly connected to both ends of the female connector plate 21, and one side of the female connector plate 21 is fixedly connected to one end of the base plate 11.

[0043] In this embodiment, the cross section of the connecting part 18 is the same as that of the female connecting plate 21, but the connecting part 18 has a groove perpendicular to the bending part 17, so that it can be bent together with the bending part 17.

[0044] In a further embodiment, the end of the female connector 21 away from the base plate 11 is a compensation part 23, and the receiving plate 31 is fixedly connected to the inner side of one end of the base plate 11.

[0045] In this embodiment, the compensation part 23 compensates for the deformation of the deformation protrusion 22 after deformation occurs, and the distance between the two ventilation ducts during assembly will become smaller.

[0046] In a further embodiment, the side of the receiving plate 31 away from the receiving plate 31 is the compensation part 2 34.

[0047] In this embodiment, the compensation section 2 34 is similar to the compensation section 1 23.

[0048] In a further embodiment, the top ends of the second side plate 13 and the first side plate 12 are provided with evenly distributed notches 14, which fit around the outer periphery of the mating plate 15.

[0049] In this embodiment, when the two module mechanisms 1 are spliced ​​symmetrically at the top and bottom, the side plate 13 in the upper module mechanism 1 will be aligned with the side plate 12 in the lower module mechanism 1. At this time, the mating plate 15 in the upper module mechanism 1 will be located inside the side plate 12 in the lower module mechanism 1, thus allowing the bolt 5 to pass through.

[0050] In a further embodiment, a sealing gasket 4 is provided on the outside of the bolt 5, and the sealing gasket 4 fits into the inside of the notch 14.

[0051] In this embodiment, after the two centrally symmetrical module mechanisms 1 are spliced ​​together, a groove is formed on one side at the notch 14, so that the sealing gasket 4 can be embedded and sealed, and the two module mechanisms 1 are fixed by the docking plate 15 to complete the splicing to form a unit of the through pipe.

[0052] The working principle of this utility model is as follows:

[0053] When the module mechanism 1, female connection mechanism 2 and male connection mechanism 3 are manufactured and transported, they can be unfolded and stacked together, which facilitates transportation and does not occupy space, thereby reducing transportation costs. When transported to the assembly area, the side plate 12 and the side plate 23 can be bent at ninety degrees along the bending part 17 and perpendicular to the bottom plate 11. Then, the two bent module mechanisms 1 are spliced ​​together symmetrically at the center. Then, the sealing gasket 4 can be inserted into the notch 14 at the splicing point of the two module mechanisms 1, and then locked by the mating plate 15 to finally form the unit ventilation duct.

[0054] After the ventilation duct is assembled into a unit by splicing two modular mechanisms 1, it can be connected front to back so that the male connection mechanism 3 of one ventilation duct can be inserted into the inner side of the female connection mechanism 2 of another ventilation duct. After insertion, due to the toughness of the male connection plate 32, the recessed part 33 can be inserted into the inner side of the deformable protrusion 22. After completion, the deformable protrusion 22 and the recessed part 33 are deformed by clamping them from the outside of the deformable protrusion 22. This completes the assembly. Due to the deformation of the recessed part 33 and the deformable protrusion 22, its airtightness can be guaranteed to prevent the leakage of gas in the duct.

[0055] Based on the disclosure and teachings of the above specification, those skilled in the art can make changes and modifications to the above embodiments. Therefore, this utility model is not limited to the specific embodiments disclosed and described above, and some modifications and changes to this utility model should also fall within the protection scope of the claims of this utility model. Furthermore, although some specific terms are used in this specification, these terms are only for convenience of explanation and do not constitute any limitation on this utility model.
