A type of air duct with adapter connectors

Abstract

This utility model relates to the field of duct technology, specifically to a duct with adaptable connectors, including a duct body. Connector 1 and connector 2 are fixed to both ends of the duct body. Connector 1 has an integrally formed alignment plate on its surface, and connector 2 has an alignment slot on its surface. When two sets of duct bodies are assembled end-to-end, the beneficial effect is that by providing connector 1 and connector 2 at both ends of the duct body, with connector 1 having an integrally formed alignment plate and connector 2 having an alignment slot, the alignment plate is inserted into the alignment slot during assembly. Since the alignment plate is annular and the alignment slot is annular, this structure ensures accurate alignment of the two sets of duct bodies, avoiding misalignment during assembly, thereby ensuring uniform airflow distribution in the ventilation system, reducing ventilation resistance, and improving ventilation efficiency.

Description

Technical Field

[0001] This utility model relates to the field of air duct technology, specifically to an air duct with an adapter connector. Background Technology

[0002] In ventilation systems, ductwork is a crucial component, used to transport air and meet the ventilation and air conditioning needs of buildings. In practical applications, due to factors such as building structure and ventilation layout, it is often necessary to splice and install multiple sections of ductwork.

[0003] Traditional duct splicing methods have several problems. Firstly, during splicing, it's difficult to ensure accurate alignment of the two duct sections, leading to misalignment. This not only affects the overall performance of the ventilation system but can also cause uneven airflow distribution, increasing ventilation resistance and reducing efficiency. Secondly, traditional splicing methods lack sealing, making leaks at the joints prone to occur, resulting in energy waste and potentially impacting indoor comfort. Furthermore, the lack of effective pre-positioning measures during splicing allows relative displacement of the two duct sections before bolts and other fasteners are installed, complicating installation and increasing difficulty and time costs.

[0004] Therefore, developing a duct with compatible connectors to solve problems such as difficulty in alignment, poor sealing, and inconvenient installation in the traditional duct splicing process is of great practical significance. Utility Model Content

[0005] The purpose of this invention is to provide a duct with a compatible connector to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a duct with adaptable connectors, comprising a duct body, wherein connector one and connector two are fixed at both ends of the duct body respectively, connector one has an alignment plate integrally formed on its surface, and connector two has an alignment slot on its surface, wherein when two sets of duct bodies are assembled end to end, the alignment plate at the end of one set of duct bodies is inserted into the alignment slot at the end of the other set of duct bodies, and bolt holes are formed on the surfaces of both the alignment plate and the alignment slot, and the two sets of bolt holes pass through connector one and connector two respectively.

[0007] Preferably, both connector one and connector two are ring plate structures, and the inner ring opening size of connector one and connector two is equal to the pipe opening size of the duct body.

[0008] Preferably, the alignment slot is an annular groove, the alignment plate is an annular plate, and there are multiple bolt holes arranged in a rectangle.

[0009] Preferably, both connector one and connector two have reserved grooves on their bottom and top surfaces. Half studs are fixed on the surface of the reserved grooves. The half studs have a semi-cylindrical structure. After the two sets of air duct bodies are spliced ​​end to end, connector one and connector two are abutted together. At this time, the two half studs are assembled into a stud, and a nut is screwed onto the stud.

[0010] Preferably, a sealing gasket is fixed on the surface of both connector one and connector two. The sealing gasket has an annular plate structure. After the stud and nut are screwed together, the sealing gasket is clamped between connector one and connector two.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] This utility model proposes a duct with adaptable connectors. Connector 1 and connector 2 are respectively provided at both ends of the duct body. Connector 1 has an integrally formed alignment plate on its surface, and connector 2 has an alignment slot on its surface. When assembling the two sets of duct bodies end to end, the alignment plate is inserted into the alignment slot. Because the alignment plate is annular and the alignment slot is annular groove, this structure ensures accurate alignment of the two sets of duct bodies, avoiding misalignment during assembly. This ensures uniform airflow distribution in the ventilation system, reduces ventilation resistance, and improves ventilation efficiency.

[0013] Both connector one and connector two have a ring-shaped sealing gasket fixed to their surfaces. After the two sets of ductwork are spliced, the bolts are tightened through the bolt holes on the surfaces of connector one and connector two, and the studs and nuts are screwed in. The sealing gasket is then clamped between connector one and connector two. This design effectively improves the sealing performance at the splice, prevents air leakage, reduces energy waste, and ensures the comfort of the indoor environment.

[0014] Both connector one and connector two have pre-drilled grooves on their bottom and top surfaces, with semi-studs fixed to the surfaces of these grooves. After the two ductwork bodies are aligned end-to-end, before installing the bolts, the nuts are screwed onto the studs assembled from the two semi-studs. At this point, connector one and connector two are connected, achieving pre-positioning of the two sets of ductwork bodies. This function prevents relative displacement between the two sets of ductwork bodies during bolt installation, reducing installation difficulty, improving installation efficiency, and saving installation time and labor costs.

[0015] Both the alignment plate and the alignment slot have bolt holes on their surfaces, and there are multiple bolt holes arranged in a rectangle. By passing bolts through these bolt holes and tightening them, connector one and connector two can be firmly connected, further ensuring the stability of the two sets of air duct bodies after splicing, and ensuring the stability and reliability of the ventilation system during long-term operation.

[0023] To make the objectives, technical solutions, and advantages of this utility model clear and complete, the embodiments of this utility model will be further described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only some, not all, embodiments of this utility model, and are merely used to explain the embodiments of this utility model. They are not intended to limit the embodiments of this utility model. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0024] Please see Figures 1 to 6This utility model provides a technical solution: a duct with adaptable connectors, including a duct body 1, with connector 2 and connector 3 fixed at both ends of the duct body 1 respectively. Both connector 2 and connector 3 are ring plate structures, and the inner ring size of connector 2 and connector 3 is equal to the pipe opening size of the duct body 1. The surface of connector 2 is integrally formed with an alignment plate 4, and the surface of connector 3 is provided with an alignment slot 5. When two sets of duct bodies 1 are assembled end to end, the alignment plate 4 at the end of one set of duct bodies 1 is inserted into the alignment slot 5 at the end of the other set of duct bodies 1. The surfaces of the alignment plate 4 and the alignment slot 5 are provided with bolt holes 6, and the two sets of bolt holes 6 pass through connector 2 and connector 3 respectively. The alignment slot 5 is an annular groove, the alignment plate 4 is an annular plate, and there are multiple bolt holes 6 arranged in a rectangle. When the two duct bodies 1 are spliced ​​end to end, the alignment plate 4 and the alignment slot 5 are matched to align the two sets of duct bodies 1. Then, the bolts are passed through the bolt holes 6 on the surfaces of connector 1 2 and connector 2 3 and locked. In this way, the two sets of duct bodies 1 are aligned and fixed, and the sealing gasket 10 is clamped between connector 1 2 and connector 2 3 to improve the sealing performance.

[0025] Both connector 1 (2) and connector 2 (3) have pre-drilled grooves (7) on their bottom and top surfaces. Semi-studs (8) are fixed to the surfaces of the grooves (7). The semi-studs (8) have a semi-cylindrical structure. After the two sets of duct bodies (1) are spliced ​​end-to-end, connector 1 (2) and connector 2 (3) abut together, at which point the two semi-studs (8) are assembled into a stud, and a nut (9) is screwed onto the stud. Sealing gaskets (10) are fixed to the surfaces of both connector 1 (2) and connector 2 (3). Sealing gaskets (10) have annular plate-like structures. After the stud and nut (9) are screwed together, the sealing gasket (10) is clamped between connector 1 (2) and connector 2 (3). When the two duct bodies (1) are aligned end-to-end, before installing bolts, to achieve pre-limiting of the two sets of duct bodies (1), the nut (9) is screwed onto the semi-stud (8). At this point, connector 1 (2) and connector 2 (3) are connected together. Bolts are then installed to reinforce the connection between connector 1 (2) and connector 2 (3).

[0026] Instructions for using ducts with compatible connectors:

[0027] Prepare the required number of duct bodies 1, and corresponding bolts, nuts 9, and other installation accessories. Pick up two sets of duct bodies 1 and align the alignment plate 4 on the connector 2 at the end of one set of duct bodies 1 with the alignment slot 5 on the connector 3 at the end of the other set of duct bodies 1. Slowly push the two sets of duct bodies 1 so that the alignment plate 4 is inserted into the alignment slot 5. The alignment plate 4 and the alignment slot 5 will then align the two sets of duct bodies 1. Before installing the bolts, to pre-limit the two sets of duct bodies 1, screw the nuts 9 onto the studs assembled from two half-studs 8. At this point, connector 2 and connector 3 are initially connected by the nuts 9 and the studs, preventing displacement of the two sets of duct bodies 1 during subsequent installation. Prepare the bolts and pass them sequentially through the corresponding bolt holes 6 on the surfaces of connector 2 and connector 3. Multiple bolt holes 6 are arranged in a rectangular pattern to ensure connection stability. Use tools to tighten the bolts passing through bolt holes 6, firmly connecting connector 1 2 and connector 2 3, thus fixing the two sets of duct bodies 1. A ring-shaped sealing gasket 10 is fixed to the surface of both connector 1 2 and connector 2 3. After the studs and nuts 9 are screwed together and the bolts are tightened, the sealing gasket 10 is clamped between connector 1 2 and connector 2 3, thereby improving the sealing performance at the joint of the two sets of duct bodies 1.
