Description

Technical Field

[0001] This utility model relates to the field of ventilation duct splicing technology, specifically a ventilation duct that is easy to splice. Background Technology

[0002] Ventilation ducts are piping systems used for air transport and distribution, and typically consist of components such as pipes, elbows, tees, and reducers.

[0003] The basic components of ventilation ducts include pipes, elbows, tees, reducers, reducers, and branch pipes. The common material for ventilation ducts is metal, such as galvanized steel, aluminum, and stainless steel.

[0004] Currently, ventilation ducts are divided into two types: plate flange ducts and angle steel flange ducts. Angle steel flange ducts have better stability but higher cost; plate flange ducts have lower stability than angle steel flange ducts and have a higher cost.

[0005] However, whether it's a duct with a common plate flange or an angle steel flange, flange plates are usually pre-installed or welded at both ends of the duct for easier splicing and installation. These flange plates provide connection points, allowing the duct sections to be firmly connected together. However, this also means that the measurement and cutting of the duct must be very precise to ensure that there is no temperature difference when the flanges are pre-installed or welded. The precision requirements are very high, but errors are inevitable during measurement and cutting, resulting in missing ducts during installation. This requires rework, installing or welding flange plates at both ends of the missing ventilation ducts, and then splicing them together. This is inconvenient and slow. Utility Model Content

[0006] The purpose of this invention is to provide a ventilation duct that is easy to assemble, so as to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] A ventilation duct that is easy to assemble includes a main ventilation duct, a splicing ventilation duct, and a splicing fastening assembly. One end of the splicing ventilation duct is spliced ​​inside the main ventilation duct, and the splicing fastening assembly is located between the main ventilation duct and the splicing ventilation duct.

[0009] The main ventilation duct includes a ventilation pipe body, which is a cylindrical structure with open ends and a hollow interior. A splicing flange plate is provided on the outer circumferential wall of one end of the ventilation pipe body, and a splicing retaining ring is provided on the outer circumferential wall of the other end of the ventilation pipe body.

[0010] As a preferred embodiment of this utility model, the spliced ​​ventilation duct includes a spliced ​​pipe body, which is a cylindrical structure with open ends and a hollow interior. One end of the spliced ​​pipe body extends into the ventilation duct body, and the outer circumferential wall of the spliced ​​pipe body abuts against the inner circumferential wall of the ventilation duct body.

[0011] As a preferred embodiment of this utility model, the splicing and fastening assembly includes an elastic limiting seal ring and a fastener. The elastic limiting seal ring is arranged in a circular structure and is sleeved on the outer circumferential wall of the splicing pipe.

[0012] As a preferred embodiment of this utility model, the inner diameter of the elastic limiting sealing ring is less than or equal to the outer diameter of the splicing pipe body, and the outer diameter of the elastic limiting sealing ring is equal to the outer diameter of the splicing retaining ring.

[0013] As a preferred embodiment of this utility model, the fastener includes a two-section fastening clamp, and the inner circumferential wall of the fastening clamp is provided with a wrapping groove for wrapping the elastic limiting sealing ring and the splicing retaining ring. The fastening clamp engages with the outside of the elastic limiting sealing ring and the splicing retaining ring located between the ventilation pipe body and the splicing pipe body.

[0014] As a preferred embodiment of this utility model, the end of the fastening clamp is provided with a fastening bolt.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] In response to the problems mentioned in the background art, this application achieves rapid and stable splicing by using splicing snap rings, as well as matching elastic limiting sealing rings and fastening clamps;

[0017] The application of elastic limiting seal rings greatly enhances the sealing performance at the interface and reduces the possibility of air leakage;

[0018] The fast and stable splicing technology greatly shortens the installation time and improves work efficiency. By enhancing sealing and stability, it improves the overall performance of the ventilation system, ensuring indoor air quality. Due to the more secure connection, it reduces the maintenance needs caused by loose connections, thereby reducing long-term maintenance costs.

[0019] The spliced ​​ventilation duct includes a ventilation duct body and a splicing pipe body. One end of the spliced ​​pipe body extends into the interior of the ventilation duct body, with its outer circumferential wall abutting against the inner circumferential wall of the ventilation duct body, ensuring connection stability. An elastic limiting seal ring, with a circular structure, is fitted onto the outer circumferential wall of the spliced ​​pipe body. This design effectively prevents air leakage and enhances sealing. The elastic limiting seal ring also limits the splicing position, preventing further displacement of the spliced ​​pipe body within the ventilation duct body. The outer wall of the elastic limiting seal ring abuts against the outer wall of the splicing retaining ring, preventing air leakage at the splice and providing further limitation. Fasteners include two-section fastening clamps with a groove on the inner circumferential wall for wrapping the elastic limiting seal ring and the splicing retaining ring. The fastening clamp engages with the elastic limiting seal ring and the splicing retaining ring located between the ventilation duct body and the spliced ​​pipe body, and is secured by fastening bolts. This achieves a quick and stable splicing, with easy adjustment of the splicing position and convenient installation.

[0027] To facilitate understanding of this utility model, a more comprehensive description of the utility model will be given below with reference to the accompanying drawings, which show several embodiments of the utility model. However, the utility model can be implemented in different forms and is not limited to the embodiments described in the text. On the contrary, these embodiments are provided to make the disclosure of the utility model more thorough and comprehensive. Example

[0028] Please see Figure 1-5 This utility model provides a technical solution: a ventilation duct that is easy to assemble, including a main ventilation duct 1, an assembly ventilation duct 2, and an assembly for fastening 3. One end of the assembly ventilation duct 2 is spliced ​​inside the main ventilation duct 1, and the assembly for fastening 3 is located between the main ventilation duct 1 and the assembly ventilation duct 2. The main ventilation duct 1 includes a ventilation pipe body 11, which is a cylindrical structure with open ends and a hollow interior. An assembly flange plate 12 is provided on the outer circumferential wall of one end of the ventilation pipe body 11, and an assembly retaining ring 13 is provided on the outer circumferential wall of the other end of the ventilation pipe body 11. The assembly ventilation duct 2 includes... The splicing pipe body 21 is a cylindrical structure with open ends and a hollow interior. One end of the splicing pipe body 21 extends into the ventilation pipe body 11, and the outer circumferential wall of the splicing pipe body 21 abuts against the inner circumferential wall of the ventilation pipe body 11. The splicing fastening component 3 includes an elastic limiting sealing ring 31 and a fastener 32. The elastic limiting sealing ring 31 is a ring structure and is sleeved on the outer circumferential wall of the splicing pipe body 21. The inner diameter of the elastic limiting sealing ring 31 is less than or equal to the outer diameter of the splicing pipe body 21, and the outer diameter of the elastic limiting sealing ring 31 is equal to the outer diameter of the splicing retaining ring 13.

[0029] It should be noted that in this embodiment, the rapid splicing of the ventilation duct is achieved by using the splicing snap ring 13 and the matching elastic limiting sealing ring 31. This design not only simplifies the installation process but also improves the stability of the connection.

[0030] The elastic limiting sealing ring 31 is set in a circular structure and is sleeved on the outer circumferential wall of the splicing pipe body 21. This design can effectively prevent air leakage and enhance the sealing performance. At the same time, the elastic limiting sealing ring 31 limits the splicing position and prevents the splicing pipe body 21 from continuing to move inside the ventilation pipe body 11. The outer wall of the elastic limiting sealing ring 31 abuts against the outer wall of the splicing retaining ring 13 to prevent air leakage at the splicing point and limit the position at the same time.

[0031] The splicing duct includes a ventilation duct body 11 and a splicing pipe body 21. One end of the splicing pipe body 21 extends into the ventilation duct body 11, with its outer circumferential wall abutting against the inner circumferential wall of the ventilation duct body 11 to ensure the stability of the connection. The elastic limiting sealing ring 31 is set in a circular structure and is sleeved on the outer circumferential wall of the splicing pipe body 21. The design can effectively prevent air leakage and enhance the sealing performance. At the same time, the elastic limiting sealing ring 31 limits the splicing position to prevent the splicing pipe body 21 from continuing to move inside the ventilation duct body 11. The outer wall of the elastic limiting sealing ring 31 abuts against the outer wall of the splicing retaining ring 13 to prevent air leakage at the splicing point and limit the position. The elastic limiting sealing ring 31 makes it easy to adjust the position according to the splicing position requirements. The splicing is convenient. The ventilation duct body 11 and the splicing pipe body 21 do not need to be drilled for connection and can be reused, saving costs.

[0032] The fast and stable splicing technology greatly shortens installation time and improves work efficiency. By enhancing sealing and stability, it improves the overall performance of the ventilation system, ensuring indoor air quality. Due to the more secure connection, it reduces maintenance needs caused by loose connections, thereby reducing long-term maintenance costs.

[0033] Please see Figure 1 , 3 4 and 5, the fastener 32 includes a two-section fastening clamp 321, the inner circumferential wall of the fastening clamp 321 is provided with a wrapping groove 322 for wrapping the elastic limiting sealing ring 31 and the splicing retaining ring 13, the fastening clamp 321 is engaged with the outside of the elastic limiting sealing ring 31 and the splicing retaining ring 13 located between the ventilation pipe body 11 and the splicing pipe body 21, and the end of the fastening clamp 321 is provided with a fastening bolt 323.

[0034] It should be noted that, in this embodiment, the fastener 32 includes a two-section fastening clamp 321, with a wrapping groove 322 on its inner circumferential wall for wrapping the elastic limiting sealing ring 31 and the splicing retaining ring 13. The fastening clamp 321 engages with the elastic limiting sealing ring 31 and the splicing retaining ring 13 located between the ventilation pipe body 11 and the splicing pipe body 21, and is fixed by fastening bolts 323;

[0035] The splicing position is easy to adjust, and can be flexibly adjusted according to actual needs, which improves the flexibility and adaptability of installation. The fast and stable splicing technology greatly shortens the installation time and improves work efficiency. By enhancing sealing and stability, it improves the overall performance of the ventilation system and ensures indoor air quality. Because the connection is more secure, it reduces the maintenance needs caused by loose connections, thereby reducing long-term maintenance costs.

[0036] The working process of this utility model:

[0037] During use, depending on the splicing position, the elastic limiting sealing ring 31 is fitted onto the outer circumferential wall of the splicing pipe body 21. One end of the splicing pipe body 21 extends into the interior of the ventilation pipe body 11, with its outer circumferential wall abutting against the inner circumferential wall of the ventilation pipe body 11. The outer wall of the elastic limiting sealing ring 31 abuts against the outer wall of the splicing retaining ring 13 to prevent air leakage at the splicing point and to limit the movement. The fastening clamp 321 is then engaged with the elastic limiting sealing ring 31 and the splicing retaining ring 13 located between the ventilation pipe body 11 and the splicing pipe body 21. At this time, the elastic limiting sealing ring 31 and the splicing retaining ring 13 are engaged inside the wrapping groove 322 and fixed by the fastening bolt 323. The splicing stability is checked by pulling and adjusted by the fastening bolt 323.
