Description

Technical Field

[0001] This utility model relates to the field of duct installation technology, specifically to a modular duct connection structure that facilitates rapid installation. Background Technology

[0002] Ductwork structures are piping systems used for air transport and distribution. They typically consist of the duct body and various connectors and fittings. The duct body is generally made of metals such as galvanized steel sheets, or non-metals such as fiberglass and PVC. Connectors include flanges and bolts, used to connect the various parts of the duct and ensure sealing and stability. Fittings include elbows, tees, and crosses, which can change the direction of airflow and allow airflow to branch or converge. Ductwork structures are widely used in ventilation, air conditioning, and purification systems, effectively delivering treated air to various locations to meet indoor comfort and air quality requirements.

[0003] Currently, in duct installation, flanges and bolts are commonly used to connect ducts. To further enhance the sealing effect, sealing strips or gaskets are carefully placed at the joints to prevent air leakage. However, even with these seemingly comprehensive measures, the planar connection method still reveals significant drawbacks after prolonged use. Because duct systems face complex conditions such as temperature changes and mechanical vibrations during operation, the stress at the joints constantly changes. Over time, gaps easily form at the joints, leading to air leakage. Utility Model Content

[0004] To solve the above-mentioned problems, this utility model proposes a modular duct connection structure that changes the planar docking method to a plug-in docking method and sets up a multi-layered anti-leakage structure to effectively prevent duct leakage after a long period of time. This structure is easy to install and quick to install.

[0005] To solve the above-mentioned technical problems, the technical solution proposed by this utility model is as follows: a modular duct connection structure that is easy to install quickly, including a duct body, wherein a connecting pipe 1 and a connecting pipe 2 are integrally formed at both ends of the duct body, the connecting pipe 2 can be tightly inserted into the connecting pipe 1, and a plurality of sealing rings are provided on the outer side wall of the connecting pipe 2. The outer side wall of the sealing ring is flat at the end near the duct body and inclined at the end away from the duct body with a gradually decreasing outer diameter. The connecting pipe 1 and the connecting pipe 2 are fixed together by a plurality of screws.

[0006] Furthermore, the width of connecting pipe one and connecting pipe two is the same, the inner diameter of connecting pipe one is larger than the inner diameter of the duct body, and it matches the outer diameter of connecting pipe two.

[0007] Furthermore, a sealing gasket is provided on the end face of the duct body that connects to the connecting pipe one, located on the inner side of the connecting pipe one.

[0008] Furthermore, there are at least two sealing rings that are equidistantly distributed.

[0009] Furthermore, the first connecting pipe is provided with several screw holes one on the side wall near the main body of the duct, and the second connecting pipe is provided with several screw holes two on the side wall away from the main body of the duct, and the screw holes two correspond one-to-one with the screw holes one.

[0010] Furthermore, the screw holes one and two are equidistantly distributed around the side walls of the connecting pipe one and connecting pipe two, respectively.

[0011] Furthermore, a sealing ring is provided on the second connecting pipe at the second screw hole, and a through hole matching the second screw hole is provided on the sealing ring.

[0012] Compared with existing technologies, this invention has the following advantages: the duct body is fixed by inserting and connecting pipes one and two, making duct connection simpler, faster, and more efficient. The multiple leak-proof structures greatly improve sealing performance. Firstly, the multiple sealing rings on the outer wall, with their special flat and bevel design, form a tight fit during insertion, achieving multiple seals and effectively preventing air leakage. Secondly, the sealing gaskets at duct joints further enhance sealing, filling any gaps. Furthermore, the sealing rings at screw connections also prevent air leakage. These multiple leak-proof structures work together to effectively prevent duct leakage even after prolonged use, ensuring the stability and reliability of the duct system, reducing energy waste caused by leakage, extending the duct's service life, and lowering maintenance costs.

[0018] The present invention will now be described in further detail with reference to the accompanying drawings.

[0019] Combined with appendix Figure 1 Appendix Figure 3A modular duct connection structure for easy and quick installation includes a duct body 1. Both ends of the duct body 1 are integrally formed with a connecting pipe 1 (2) and a connecting pipe 2 (3). The connecting pipe 2 (3) can be tightly inserted into the connecting pipe 1 (2). The connecting pipe 1 (2) and connecting pipe 2 (3) have the same width. The inner diameter of the connecting pipe 1 (2) is larger than the inner diameter of the duct body 1 and matches the outer diameter of the connecting pipe 2 (3), facilitating a tight insertion of the connecting pipe 2 (3) into the connecting pipe 1 (2), ensuring a stable connection and smooth airflow within the duct. A sealing gasket 5 is provided on the end face of the duct body 1 where it connects to the connecting pipe 1 (2), located inside the connecting pipe 1 (2), effectively preventing airflow leakage at the connection point, further enhancing the sealing performance of the duct connection structure and improving the working efficiency of the duct system.

[0020] Combined with appendix Figure 2 Appendix Figure 4 The outer wall of the connecting pipe 2 3 is provided with several sealing rings 4. The outer wall of the sealing ring 4 is flat at the end near the air duct body 1 and inclined at the end away from the air duct body 1 with a gradually decreasing outer diameter. There are no less than two sealing rings 4 and they are evenly distributed. Multiple sealing rings 4 can form a multiple sealing effect, which significantly improves the sealing performance of the connection structure and reduces the possibility of air leakage.

[0021] Combined with appendix Figure 1 Appendix Figure 2 Appendix Figure 4 The connecting pipe 2 and connecting pipe 3 are fixed together by a number of screws. Connecting pipe 2 has a number of screw holes 6 on its side wall near the duct body 1, and connecting pipe 3 has a number of screw holes 7 on its side wall away from the duct body 1. Screw holes 7 correspond one-to-one with screw holes 6, facilitating screw installation and making the connection between connecting pipe 2 and connecting pipe 3 more accurate and convenient. The screw holes 6 and 7 are equidistantly distributed around the side walls of connecting pipe 2 and connecting pipe 3, ensuring a uniform distribution of the fixing force of the screws on the connection structure, guaranteeing the stability and reliability of the connection. A sealing ring 8 is provided on connecting pipe 3 at screw hole 7. The sealing ring 8 has a through hole matching screw hole 7, which prevents air leakage at the screw connection and provides some protection to the screws, extending the service life of the connection structure.

[0022] The specific implementation method of this utility model is as follows: First, prepare two duct bodies 1 to be connected, and bring the connecting pipe 1 2 on one duct body 1 close to the connecting pipe 2 3 on the other duct body 1. Since the inner diameter of connecting pipe 1 2 is larger than the inner diameter of the duct body 1 and matches the outer diameter of connecting pipe 2 3, insert connecting pipe 2 3 into the adjacent connecting pipe 1 2, so that connecting pipe 2 3 is tightly inserted into connecting pipe 1 2. At this time, several equally spaced sealing rings 4 on the outer wall of connecting pipe 2 3 play a role. The plane of its outer wall near the end of the duct body 1 fits against the inner wall of connecting pipe 1 2, forming a preliminary seal, and the inclined surface away from the end of the duct body 1 facilitates the sliding of connecting pipe 1 2. At the same time, the end face of connecting pipe 2 3 is in close contact with the sealing gasket 5, further enhancing the sealing performance of the connection. Next, check the screw hole 1 6 on the side wall of connecting pipe 1 2 near the end of the duct body 1 and the screw hole 2 7 on the side wall of connecting pipe 2 3 away from the end of the duct body 1 to ensure that they correspond one-to-one. After passing the screw through the through hole on the sealing ring 8 at screw hole 2 7, screw it into screw hole 1 6. Fix the connecting pipe 1 2 and connecting pipe 2 3 with the screw. The sealing ring 8 prevents air leakage at the screw connection, and the connection and installation of the air duct is completed.
