Description

Technical Field

[0001] The utility model relates to the technical field of assembled ventilation ducts, in particular to an assembled environmentally friendly and energy-saving ventilation duct. Background Art

[0002] Prefabricated ventilation ducts refer to air ducts that are prefabricated in a standardized factory and assembled in modular form on site. This type of duct system can greatly simplify on-site installation work, improve construction efficiency, and ensure the quality and performance of the air ducts.

[0003] Traditional prefabricated ventilation ducts focus on quick installation and disassembly to improve construction efficiency. This makes it difficult to ensure the stability and sealing of each joint when splicing multiple ducts. At the same time, existing prefabricated ventilation ducts also have certain limitations in terms of thermal insulation and sound insulation, and cannot meet the usage requirements in some specific environments. Therefore, we have proposed an assembled environmentally friendly and energy-saving ventilation duct to solve the above problems. Utility Model Content

[0004] The purpose of the utility model is to solve the shortcomings of the prior art in that when multiple pipes of traditional assembled ventilation ducts are spliced together, it is difficult to ensure the stability and sealing of the joints and lack effective insulation and sound insulation, which makes it impossible to meet the requirements of use in specific environments, and to propose an assembled environmentally friendly and energy-saving ventilation duct.

[0005] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0006] An assembled environmentally friendly and energy-saving ventilation duct includes a duct body, square flanges are fixedly provided at both ends of the duct body, and mounting holes are provided on both square flanges for splicing and fixing multiple duct bodies. A partition is provided inside the duct body for dividing the internal channel of the duct body into an air inlet channel and an air outlet channel. The ventilation duct also includes:

[0007] The limiting component is set on the corresponding square flange and is used to limit the position when splicing two pipe bodies, making installation easier;

[0008] Sealing components are arranged at the openings at both ends of the pipe body to ensure sealing when the two pipe bodies are spliced together.

[0009] In one possible design, the limiting assembly includes two positioning blocks, which are symmetrically fixed on one side of one of the square flanges. The top and bottom of the other square flange are provided with positioning grooves corresponding to the positioning blocks. The two positioning blocks are clamped with adjacent positioning grooves. By setting two positioning blocks and positioning grooves, the positions of the two pipe bodies are limited during splicing and installation, which is convenient for installation.

[0010] In one possible design, the sealing assembly includes two sealing rings, which are fixedly arranged at the two end openings of the pipe body respectively. A sealing groove is provided at the two end openings of the pipe body, and four positioning columns are provided at equal intervals in the sealing groove. The sealing ring passes through the four positioning columns and is located in the sealing groove. The sealing groove and the four positioning columns therein fix the position of the sealing ring when the two pipe bodies are spliced and installed to prevent it from falling off or deformation that affects the sealing.

[0011] In a possible design, the inner wall of the pipe body is provided with a thermal insulation layer for thermal insulation.

[0012] In a possible design, a sound insulation layer is provided inside the pipe body, and the sound insulation layer is located between the inner wall of the pipe body and the thermal insulation layer.

[0013] In a possible design, the top and bottom of the partition both penetrate the sound insulation layer and the thermal insulation layer and are fixedly connected to the inner wall of the pipe body.

[0014] In a possible design, sealing strips are provided on both sides of the partition close to the openings at both ends of the pipe body, which are used to seal when the two partitions therein are clamped together when the two pipe bodies are spliced.

[0015] In this application, first, during installation, the square flanges of the two pipe bodies are brought close to each other and accurately aligned through the positioning blocks and positioning grooves in the limit assembly. The clamping structure of the positioning blocks and positioning grooves ensures the stability and accuracy of the two pipe bodies when splicing;

[0016] During the process, the sealing rings in the sealing assembly are installed at the openings at both ends of the pipe body and fixed by the positioning columns in the sealing groove. When the two pipe bodies are spliced together, the sealing rings are compressed and fit tightly at the connection, achieving a good sealing effect.

[0017] The inner wall of the pipe body is provided with a thermal insulation layer and a sound insulation layer. Through the joint action of these two layers, good thermal insulation and sound insulation effects are achieved. At the same time, the partition divides the internal channel of the pipe body into an air inlet channel and an air outlet channel, ensuring the normal operation of the ventilation system. At the same time, the sealing strips arranged on both sides of the partition seal the two partitions when the two pipe bodies are spliced, thereby preventing the air inlet channel and the air outlet channel from communicating with each other. Beneficial effects

[0018] In the utility model, the assembled environmentally friendly and energy-saving ventilation duct divides the internal channel of the duct body into an air inlet channel and an air outlet channel by the provided partition, thereby integrating the air inlet and the air outlet and improving practicality;

[0019] In the present invention, the assembled environmentally friendly and energy-saving ventilation duct not only improves the efficiency and accuracy of installation by providing a limit assembly and a sealing assembly, but also prevents air leakage and noise transmission, thereby improving the overall performance of the ventilation system.

[0020] In the present invention, the assembled environmentally friendly and energy-saving ventilation duct achieves good thermal insulation and sound insulation effects by arranging a thermal insulation layer and a sound insulation layer inside the duct body, meeting the use requirements in different environments;

[0021] In the present invention, the assembled environmentally friendly and energy-saving ventilation duct,

[0022] In the utility model, the internal channel of the duct body is divided into an air inlet channel and an air outlet channel by the provided partition, so that the air inlet and air outlet are integrated, thereby improving practicality.

[0027] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0028] Example 1: Reference Figure 1-3A ventilation duct comprises: a duct body 1, with square flanges 2 fixedly provided at both ends of the duct body 1. The two square flanges 2 are each provided with a plurality of mounting holes for splicing and fixing multiple duct bodies 1. A partition 3 is provided inside the duct body 1. The function of the partition 3 is to divide the internal channel of the duct body 1 into an air inlet channel and an air outlet channel, thereby achieving functional differentiation of the ventilation duct. In order to further optimize the installation and sealing performance of the assembled ventilation duct, the present invention also provides a limit assembly and a sealing assembly.

[0029] The purpose of the position-limiting assembly is to facilitate positioning when splicing two pipe bodies 1, thereby simplifying the installation process. Specifically, the position-limiting assembly includes two positioning blocks 201, symmetrically fixed to one side of one square flange 2. The top and bottom of the other square flange 2 are each provided with a positioning groove 202 corresponding to each positioning block 201. During splicing, the two positioning blocks 201 snap into adjacent positioning grooves 202, thereby limiting the position of the two pipe bodies 1 and making the installation process simpler and faster.

[0030] The sealing assembly is designed to ensure a good seal when the two pipe bodies 1 are joined together, preventing air leakage. The sealing assembly includes two sealing rings 4, which are fixedly mounted at the two end openings of the pipe body 1. To ensure that the sealing rings 4 remain stable during installation, sealing grooves are provided at both end openings of the pipe body 1, and four positioning posts 5 are evenly spaced within the sealing grooves. The sealing rings 4 penetrate these four positioning posts 5 and are located within the sealing grooves, ensuring that the sealing rings 4 remain fixed during splicing and installation, preventing them from falling off or deforming, which could affect the sealing effect.

[0031] An insulation layer 7 is provided on the inner wall of the pipe body 1 to improve the insulation performance of the ventilation duct. At the same time, in order to enhance the sound insulation effect of the ventilation duct, a sound insulation layer 6 is also provided inside the pipe body 1, and the sound insulation layer 6 is located between the inner wall of the pipe body 1 and the insulation layer 7.

[0032] The present application can be used in the technical field of assembled ventilation ducts, and can also be used in other fields applicable to the present application.

[0033] Example 2: Reference Figure 2-3 Based on the first embodiment, an improved, assembled, environmentally friendly, and energy-saving ventilation duct is applied to the technical field of assembled ventilation ducts. Furthermore, the top and bottom of the partition 3 penetrate the sound insulation layer 6 and the thermal insulation layer 7 and are fixedly connected to the inner wall of the duct body 1. This arrangement ensures the stability of the partition 3 and also helps improve the sound insulation and thermal insulation effects of the ventilation duct.

[0034] Furthermore, in order to ensure that the two partitions 3 therein can be locked together and maintain good sealing when splicing two pipe bodies 1, the present invention also provides sealing strips 8 on both sides of the partitions 3 near the openings at both ends of the pipe body 1. In this way, when splicing the two pipe bodies 1, the sealing strips 8 on the two partitions 3 will contact each other and form a good sealing effect.

[0035] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
