AI Technical Summary
Existing industrial composite ducts require disassembly during assembly to reduce the space occupied during transportation, resulting in time-consuming and labor-intensive transportation processes. Furthermore, the support rod fixing method is not convenient for multi-angle adjustment.
The design of the ductwork, which combines the movable connection of the mounting rod and the locking column with the expansion sleeve, allows the duct to be supported at a vertical angle and retracted at a horizontal angle to reduce space occupation. At the same time, it uses magnetic blocks for initial fixation and threaded connections for stable installation.
This reduces collision damage to ducts during transportation, improves assembly efficiency and transportation convenience, meets multi-angle support requirements, and adapts to different installation environments.

Abstract
Description
Technical Field
[0001] This utility model relates to the field of industrial composite air duct technology, specifically a prefabricated industrial integrated composite air duct. Background Technology
[0002] Industrial composite ducts are ventilation ducts used in the industrial field that are made of two or more different materials. They are mainly used to transport media such as air, gas, dust, and smoke to meet the needs of ventilation, dust removal, smoke exhaust, and air conditioning systems in industrial environments.
[0003] Currently, industrial composite ducts are assembled by threaded connection of individual ducts. After installation, the ducts are connected to the building wall via support rods to ensure structural stability. However, the support rods are typically fixed and perpendicular to the ducts. This method tends to occupy a large space during storage and transportation, requiring disassembly and increasing the workload and time involved in transportation. Therefore, there is a need for a composite duct that can solve these drawbacks and improve efficiency. Utility Model Content
[0004] The purpose of this utility model is to provide a prefabricated industrial integrated composite air duct to solve the problems mentioned in the background art. To solve the above technical problems, this utility model is achieved through the following technical solution:
[0005] This utility model is a prefabricated industrial integrated composite air duct, comprising:
[0006] A composite duct module, wherein the composite duct module includes a composite duct body;
[0007] The docking installation module includes symmetrical slots opened in the middle of the front and rear ends of the composite pipe. A movable frame is fixed in the middle of the inner wall of the slot, and docking installation rods are symmetrically provided at the ends of the movable frame. A shaft seat is fixed in the middle of one end of the docking installation rod, and a locking post is sleeved and fixed in the middle of the shaft seat, and extends threadedly into an expansion sleeve embedded in the building wall.
[0008] Furthermore, a shaft is fixed at the middle of the other end of the docking mounting rod, and the end of the shaft is rotatably connected to the two side walls of the movable frame.
[0009] Furthermore, the side of the mating mounting rod is in contact with the inner wall of the slot, and the outer end of the mating mounting rod extends out of the slot.
[0010] Furthermore, the composite duct module also includes a connecting frame, and threaded pipes are connected through the corners of the connecting frame.
[0011] Furthermore, a rectangular groove is provided at the middle position of the outer side of the connecting frame, and a magnetic block is embedded in the rectangular groove at one end of the composite tube, and they are magnetically attracted to each other.
[0012] Furthermore, it also includes a sliding support module, which includes a guide frame one threadedly connected to the top surface of the building and a guide frame two symmetrically fixedly connected to the upper front and rear ends of the adjacent connecting frame. A guide block one is slidably connected to the middle of the bottom end of the guide frame one, and a guide block two is slidably connected to the middle of the outer side of the guide frame two. A support frame is fixed to the middle of the bottom end of the guide block one, and the lower end of the support frame is fixed to the outer side of a set of guide blocks two.
[0013] Furthermore, one end of the guide frame 1 and the guide frame 2 is provided with a U-shaped protrusion, and the other end is provided with a U-shaped groove, and the two fit together.
[0014] This utility model has the following beneficial effects:
[0015] This invention utilizes a shaft to movably connect the mounting rod to the movable frame. When the mounting rod is at a perpendicular angle to the composite tube, a locking pin and an expansion sleeve are used to provide structural support for the composite tube. When it is at a horizontal angle to the composite tube, it is in a retracted state and is confined by a slot, which does not affect subsequent transportation and use. Furthermore, the outer side of the mounting rod protrudes outward when it is in the retracted state, and the contact between adjacent mounting rods can prevent collision damage between adjacent composite tubes during transportation, thus improving the performance and meeting the requirements.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0024] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.
[0025] Please see Figure 1-4 As shown, this utility model is a prefabricated industrial integrated composite air duct, comprising:
[0026] A composite duct module, comprising a composite duct body 11;
[0027] Composite pipe body 11 is mainly used to transport media such as air, gas, dust, and smoke, to meet the needs of ventilation, dust removal, smoke exhaust, and air conditioning systems in industrial environments.
[0028] The composite duct module also includes a connecting frame 12, and threaded pipes 13 are connected through the corners of the connecting frame 12;
[0029] Bolts are inserted into the threaded pipe 13 and tightened to fix the connecting frame 12, thereby satisfying the assembly between adjacent composite pipe bodies 11.
[0030] A rectangular groove 14 is provided at the middle of the outer side of the connecting frame 12. A magnetic block is embedded in the rectangular groove 14 at the end of a composite tube 11, and the magnetic blocks attract each other.
[0031] The rectangular groove 14 is embedded with a magnetic block. Through the mutual magnetic attraction between the relatively fitted magnetic blocks, the initial fixation between adjacent composite tubes 11 can be achieved, which is conducive to the subsequent secondary tightening of the threads.
[0032] The docking installation module includes slots 21 symmetrically opened in the middle of the front and rear ends of the composite pipe body 11. A movable frame 22 is fixed in the middle of the inner wall of the slot 21, and docking installation rods 24 are symmetrically provided at the ends of the movable frame 22. A bearing seat 25 is fixed in the middle of one end of the docking installation rod 24, and a locking post 26 is sleeved and fixed in the middle of the bearing seat 25 and threaded into the expansion sleeve embedded in the building wall.
[0033] A shaft 23 is fixed at the middle of the other end of the mounting rod 24, and the end of the shaft 23 is rotatably connected to the two side walls of the movable frame 22.
[0034] The slot 21 provides an installation environment for the movable frame 22 and a storage environment for the docking mounting rod 24. The movable frame 22 and the docking mounting rod 24 are connected by the shaft 23. The shaft 23 can be rotated to allow for multi-angle adjustment of the docking mounting rod 24 to meet storage and structural fixation needs. The shaft seat 25 meets the locking rotation requirements of the locking column 26 and provides structural support for the assembled composite tube 11 through the connection with the expansion sleeve.
[0035] The side of the mating mounting rod 24 is in contact with the inner wall of the slot 21, and the outer end of the mating mounting rod 24 extends out of the slot 21.
[0036] The mounting rod 24 protrudes after being retracted, and the collision between adjacent mounting rods 24 can protect adjacent composite pipes 11 from impact during transportation.
[0037] Working principle: Multiple composite tubes 11 are assembled and connected according to the usage requirements. First, the mutual magnetic attraction between adjacent magnetic blocks ensures the initial stability between adjacent composite tubes 11 during connection. Then, bolts are inserted into the threaded tube 13 and locked to complete the secondary locking. At this time, force can be applied to the docking mounting rod 24 so that the docking mounting rod 24 in the storage position is perpendicular to the composite tube 11. By rotating the locking pin 26 into the expansion sleeve, the assembled multiple composite tubes 11 are structurally supported. The thread of the bearing seat 25 extends into the docking mounting rod 24 to meet the expansion and contraction required for locking. When disassembling the composite tubes 11 later, the docking mounting rod 24 can be stored in the slot 21.
[0038] This solution utilizes the movable connecting mounting rod 24 to meet the structural fixation and transportation requirements of the composite tube 11, thereby improving the structural applicability and functionality and fulfilling the requirements.
[0039] Please see Figure 1-4 As shown, this embodiment is based on the above embodiment:
[0040] It also includes a sliding support module, which includes a guide frame 31 threadedly connected to the top surface of the building and a guide frame 34 symmetrically fixedly connected to the upper front and rear ends of the adjacent connecting frame 12. A guide block 32 is slidably connected to the middle of the bottom end of the guide frame 31, and a guide block 35 is slidably connected to the middle of the outer side of the guide frame 34. A support frame 33 is fixed to the middle of the bottom end of the guide block 32, and the lower end of the support frame 33 is fixed to the outer side of a set of guide blocks 35.
[0041] Guide frame 1 31 satisfies the sliding support of guide block 1 32, and guide frame 2 34 satisfies the sliding support of guide block 2 35. Through the sliding between the two, the support frame 33 can be moved to multiple positions to meet different needs. It can support the heavier end of the composite pipe 11 in time to avoid falling off.
[0042] Guide frame 1 31 and guide frame 2 34 have a U-shaped protrusion at the middle of one end and a U-shaped groove at the middle of the other end, and the two fit together.
[0043] The interlocking of the U-shaped protrusions and U-shaped grooves satisfies the assembly of the structures between multiple guide frames 31 and guide frames 34.
[0044] Working principle: During the assembly of the above-mentioned multiple composite pipes 11 and the structural support of them using the docking mounting rod 24, the guide frame 31 can be threaded to the top surface of the building, and the top middle of the support frame 33 can be fixed to the bottom end of the guide block 32. The lower end of the support frame 33 can be fixed to the outside of a set of guide blocks 35. Then, force is applied to the support frame 33 as needed. Through the sliding of the guide block 32 and the guide block 35, the support frame 33 can be moved to the required position to support the heavier end of the composite pipe 11 due to the installation angle.
[0045] This solution uses a sliding support bracket 33 to support and support the composite pipe 11, ensuring the stability of its structure and allowing for convenient relocation. This saves time and effort, is easy to use, and is suitable for supporting the composite pipe 11 in different installation environments.
