Description

Technical Field

[0001] This utility model relates to the field of magnesium clinker high crystal air duct, specifically a magnesium clinker high crystal air duct with an auxiliary docking structure. Background Technology

[0002] In modern industry and construction, the efficient and stable operation of ventilation systems is crucial. Magnesium-based polycrystalline ducts, as key components of ventilation systems, are made of special materials such as magnesium polycrystalline ducts and possess excellent fire resistance, heat insulation, and lightweight properties. They can stably transport air in various complex environments and are widely used in industries such as chemical, construction, and electronics. As the ventilation requirements of various industries continue to increase, traditional ducts have revealed many shortcomings in terms of connection, structural strength, and maintenance. There is an urgent need for a new type of magnesium-based polycrystalline duct with an auxiliary connection structure to meet the growing demand.

[0003] In traditional duct technology, the connection structure is often relatively simple and not very stable. In terms of structural strength, traditional ducts lack effective internal reinforcement structures. When subjected to large external impacts or fluctuations in internal airflow pressure, they are prone to deformation, affecting the normal use of the duct and even potentially causing duct rupture, requiring frequent replacement. In addition, traditional ducts are rarely designed for ease of maintenance and lack dedicated maintenance tracks and other facilities, making it difficult for maintenance personnel to inspect and repair the inside of the duct and to fully identify potential hazards. To address these issues, we propose a magnesium-based beaded high-crystal duct with an auxiliary connection structure. Utility Model Content

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0026] Please see Figure 1-4 A magnesium-based high-crystal air duct with an auxiliary docking structure includes an air duct body 1, a corrugated pipe 3, and an air duct body 2 5. The corrugated pipe 3 is provided on one side plane of the air duct body 1, and the air duct body 2 5 is provided on the other side plane of the corrugated pipe 3. Another set of air duct body 1 is fixedly provided on the other side of the air duct body 2 5. Multiple sets of spring support reinforcement structures are equidistantly arranged inside the air duct body 1, the corrugated pipe 3, and the air duct body 2 5.

[0027] Furthermore, on one side of the duct body 1, symmetrically fixedly installed connecting blocks 2 are mounted on both sides corresponding to the pipe opening. Connecting blocks 2 are wedge-shaped, and sliding grooves are opened on the plane of connecting blocks 2. On the other side of the duct body 1, symmetrically fixedly installed connecting blocks 7 are mounted around the pipe opening. Threaded holes are opened on connecting blocks 7. The wedge-shaped structure design of connecting blocks 2 not only plays a role in precise positioning when engaging with connecting blocks 2 15, making the positional deviation of the duct connection smaller, but also its wedge-shaped surface can distribute the force to the entire engagement surface when subjected to external force, enhancing the stability of the connection. The setting of connecting blocks 7 provides a basic structure for the connection between the duct body 1 and the corrugated pipe 3. Its threaded holes cooperate with bolts 4. During the tightening of bolts 4, the pre-tightening force generated can effectively prevent the connection from loosening, ensuring a tight connection between the duct body 1 and the corrugated pipe 3.

[0028] Furthermore, the two sides of the corrugated pipe 3 are symmetrically fixed with connecting grooves 14 around the pipe openings. The outer wall of the corrugated pipe 3 is provided with threaded holes that are connected to the inside of the connecting grooves 14. The connecting block 7 on the duct body 1 and the connecting groove 14 on the corrugated pipe 3 are engaged, and the threaded holes on the connecting block 7 and the threaded holes on the connecting groove 14 are coaxially aligned. The bolt 4 is threadedly connected to the connecting block 7 and the threaded holes on the connecting groove 14.

[0029] Furthermore, another set of connecting blocks 7 is symmetrically fixedly installed on one side of the pipe end face corresponding to the pipe opening around the pipe. The connecting blocks 7 are also provided with threaded holes. The connecting blocks 7 on the duct body 25 and the connecting groove 14 on the other side of the corrugated pipe 3 are engaged with each other. The threaded holes on the connecting blocks 7 and the threaded holes on the connecting groove 14 are coaxially aligned. The bolts 4 are threadedly connected to the connecting blocks 7 and the threaded holes on the connecting groove 14.

[0030] Furthermore, on the other side of the duct body 25, a connecting clip 2 15 is fixedly installed around the duct opening. The connecting clip 2 15 has symmetrically formed wedge-shaped grooves inside. Sliding holes communicating with the internal wedge-shaped grooves are symmetrically formed on the outer walls of both sides of the connecting clip 2 15. A threaded hole communicating with the internal wedge-shaped groove is formed on the upper surface of the connecting clip 2 15. A pressure rod 13 is slidably connected within the sliding hole of the connecting clip 2 15. A pressure plate is fixedly installed on the end face of the pressure rod 13 inside the connecting clip 2 15. A connecting hole is formed on the outer arc surface of the pressure rod 13. A screw 6 is threadedly connected within the threaded hole of the connecting clip 2 15. A fixing rod is fixedly installed on the end face of the screw 6 inside the connecting clip 2 15. The fixing rod on the screw 6... The connecting holes on the rod and the pressure rod 13 are slidably connected on the same axis. The wedge-shaped groove inside the connecting block 2 15 is tightly fitted with the wedge-shaped structure of the connecting block 1 2, forming an interlocking mechanism. This further enhances the connection stability between the duct body 1 and the duct body 2 5. When the screw 6 is rotated, the fixing rod on the screw 6 slides in the connecting hole of the pressure rod 13, pushing the pressure rod 13 to move in the sliding hole of the connecting block 2 15. The pressure plate then presses the connecting block 1 2. This structural design can control the clamping force of the pressure rod 13 by adjusting the rotation degree of the screw 6 according to actual needs, thereby adapting to the requirements of duct connection stability under different working conditions and ensuring that the duct connection parts can maintain a reliable connection state in various complex environments.

[0031] Furthermore, the wedge-shaped groove on the connecting block 2 15 engages with the connecting block 1 2, and the pressure rod 13 slides with the sliding groove on the connecting block 1 2. When using some maintenance equipment with rollers, the rollers can roll in the sliding groove to prevent the equipment from shifting during movement and ensure that maintenance operations can accurately cover all areas inside the duct.

[0032] Furthermore, maintenance rails 12 are symmetrically fixedly installed on the inner walls of both sides of the main body of the air duct 1, the corrugated pipe 3, and the main body of the air duct 2 5, and grooves are opened on the opposite surfaces of the two maintenance rails 12.

[0033] Furthermore, the spring support reinforcement structure includes support disc 1 8, spring 1 9, support disc 2 10, and spring 2 11. Multiple support discs 1 8 are equidistantly fixed on the bottom surface inside the duct body 1, corrugated pipe 3, and duct body 2 5. A guide shaft is fixedly installed on the upper surface of support disc 1 8, and spring 2 11 is fixedly installed on the upper surface of the guide shaft. Spring 1 9 is fixedly installed on the upper surface of support disc 1 8 corresponding to the periphery of the guide shaft. Support disc 2 10 is fixedly connected to the other end of spring 1 9. The upper surface of support disc 2 10 is fixedly connected to the top surface inside the duct body 1, corrugated pipe 3, and duct body 2 5. A sleeve is fixedly installed on the bottom surface of support disc 2 10, and the other end of spring 2 11 is fixedly connected to the top surface of the sleeve on support disc 2 10. The guide shaft on disc 8 provides a precise installation position for spring 11, ensuring that spring 11 will not shift during compression and tension, thus enabling it to stably perform its supporting function. The sleeve on the bottom surface of support disc 10 cooperates with spring 11, further enhancing the stability of spring 11 and preventing it from tilting or twisting under stress. Multiple support discs 8 are equidistantly distributed on the bottom surface inside the duct, which can evenly distribute the pressure borne by the duct and avoid duct deformation due to excessive local pressure. The combined structure of spring 9 and spring 11, through different elastic coefficients and installation positions, can better adapt to various complex stress conditions, comprehensively enhance the duct's resistance to pressure, effectively protect the structural integrity of the duct, and ensure the long-term stable operation of the ventilation system.

[0034] Structural Description:

[0035] Duct body 1: Duct body 1 is an important basic component of the entire ventilation system. One side of its plane is connected to the corrugated pipe 3. On one side of the pipe end, connecting blocks 12 are symmetrically installed on both sides of the pipe opening. On the other side of the pipe end, connecting blocks 7 are symmetrically installed around the pipe opening. The connecting blocks 7 are engaged with the connecting grooves 14 of the corrugated pipe 3 to achieve the initial positioning and connection between the ducts and undertake the basic task of air transportation.

[0036] Connecting Block 1 2: Connecting Block 1 2 is wedge-shaped and fixed to one side of the pipe end of the air duct body 1. The sliding groove on its plane is slidably connected with the pressure rod 13 on Connecting Block 2 15. The wedge-shaped structure is tightly engaged with the wedge-shaped groove of Connecting Block 2 15, which enhances the stability of the connection and ensures the accuracy and reliability of the air duct docking.

[0037] Corrugated pipe 3: Corrugated pipe 3 is located between duct body 1 and duct body 2, playing the role of connection and buffer. Connecting grooves 14 are symmetrically opened on both sides of the pipe end corresponding to the pipe opening. The threaded hole on the outer wall communicates with the connecting groove 14. It cooperates with the connecting block 7 of duct body 1 and duct body 2 through the connecting groove 14 and is fixed with bolts 4, which can compensate for installation errors and displacement.

[0038] Bolt 4: Bolt 4 is a key component for connecting various parts. It is threadedly connected to the connecting block 7 of the duct body 1 and the threaded hole of the connecting groove 14 of the corrugated pipe 3, respectively, to fasten the duct body 1 to the corrugated pipe 3. In the connection between the duct body 2 5 and the corrugated pipe 3, the bolt 4 is also used to achieve a tight connection, ensuring the overall structural strength of the duct.

[0039] Duct body 2 5: Duct body 2 5 is similar in structure to duct body 1. One side is connected to the corrugated pipe 3, and the other side is used to connect to another set of duct body 1, together forming a complete ventilation duct system. It is responsible for air delivery in the system, and at the same time provides an installation base for the maintenance track 12 and the spring support reinforcement structure.

[0040] Screw 6: Screw 6 is threaded into the threaded hole of connecting block 2 15. The fixing rod fixed on its inner end face is slidably connected to the connecting hole of pressure rod 13 on the same axis. By rotating screw 6, pressure rod 13 is pushed to slide in the sliding hole of connecting block 2 15, thereby pressing connecting block 1 2 and enhancing the stability of the duct connection.

[0041] Connecting block 7: Connecting block 7 is symmetrically installed on the other end of the duct body 1 and one end of the duct body 2. It has threaded holes and is engaged with the connecting groove 14 on the corrugated pipe 3. The threaded holes are coaxial with the threaded holes of the connecting groove 14. It is used with bolts 4 to realize the connection and fixation between components and is an important part of the duct connection structure.

[0042] Support disc 18: Support disc 18 is equidistantly installed on the inner bottom surface of duct body 1, corrugated pipe 3, and duct body 2 5. The upper plane is fixed with a guide shaft and spring 19 is installed around it. It serves as the basic component of the spring support reinforcement structure, providing support for spring 19 and spring 2 11, dispersing pressure, and enhancing the overall structural strength of the duct.

[0043] Spring 19: One end of spring 19 is connected to support disc 18, and the other end is connected to support disc 210. Inside the duct, it works in conjunction with spring 211 to disperse external force and internal pressure, buffer impact, effectively reduce duct deformation caused by pressure, extend the service life of the duct, and ensure the stable operation of the ventilation system.

[0044] Support disc 2 10: The upper surface of support disc 2 10 is fixedly connected to the inner top surface of duct body 1, corrugated pipe 3, and duct body 2 5. A sleeve is installed on the bottom surface. It is connected to spring 1 9 and spring 2 11 to transfer the supporting force of the spring to the inner wall of the duct, further enhancing the structural stability of the duct and ensuring the normal operation of the ventilation duct.

[0045] Spring 2 11: The lower end of Spring 2 11 is connected to the top of the guide shaft on the support disc 1 8, and the upper end is connected to the top surface of the sleeve of the support disc 2 10. Together with Spring 1 9, it enhances the air duct's resistance to pressure, buffers external force impact, protects the structural integrity of the air duct, and ensures the long-term stable operation of the ventilation system.

[0046] Inspection track 12: The inspection track 12 is symmetrically installed on both sides of the inner wall of the air duct body 1, the corrugated pipe 3, and the air duct body 2 5. The opposite sides are provided with sliding grooves. It provides a moving track for maintenance personnel or equipment, which facilitates comprehensive inspection and maintenance of the air duct, improves the convenience and efficiency of maintenance, and ensures the normal operation of the ventilation system.

[0047] Pressure rod 13: Pressure rod 13 is slidably connected in the sliding hole of connecting block 2 15. One end is fixed with a pressure plate, and a connecting hole is opened on the outer arc surface. Driven by screw 6, it slides along the sliding hole and cooperates with the sliding groove of connecting block 1 2 to press the connecting block 1 2 and enhance the stability of the duct connection.

[0048] Connecting groove 14: Connecting groove 14 is symmetrically opened around the pipe openings on both sides of the corrugated pipe 3. There are threaded holes on the outer wall that are connected to it. It is snapped into the connecting block 7 of the air duct body 1 and the air duct body 2 5 and connected by bolts 4 to achieve a tight connection between the corrugated pipe 3 and other components. It is a key part of the air duct connection structure.

[0049] Connecting Block 2 15: Connecting Block 2 has a wedge-shaped groove inside, sliding holes on both outer walls, and threaded holes on the upper surface. It engages with Connecting Block 1 2 through the wedge-shaped groove, and together with the pressure rod 13 and screw 6, it enhances the stability of the duct connection.

[0050] Working principle: During installation, the connecting block 7 of the duct body 1 engages with the connecting groove 14 of the corrugated pipe 3, ensuring that the threaded holes of the two are coaxially aligned, and then tightened with bolts 4. The connecting block 7 of the duct body 2 5 is connected and fixed to the connecting groove 14 on the other side of the corrugated pipe 3 in the same way. The wedge groove of the connecting block 2 15 engages with the connecting block 1 2. Rotating the screw 6 on the connecting block 2 15 drives the pressure rod 13 to slide in the sliding hole of the connecting block 2 15. The pressure plate of the pressure rod 13 presses against the connecting block 2, while the pressure rod 13 slides in the sliding groove of the connecting block 2. Through these structural coordinations, a tight and stable connection is achieved between the duct body 1, the corrugated pipe 3, and the duct body 2 5, enhancing the stability of the connection and ensuring efficient and stable air delivery during the operation of the ventilation system, preventing loosening and leakage at the connection.

[0051] When the duct is subjected to external impact or internal airflow pressure fluctuations, the spring support reinforcement structure comes into play. The support disc 8 on the bottom surface inside the duct body 1, corrugated pipe 3, and duct body 2 5 bears the pressure. The springs 9 and 11 on the support disc 8 undergo elastic deformation. The springs 9 and 11 work together to disperse and transmit the pressure to the support disc 10, and then the support disc 10 transmits the support force to the inner wall of the duct. This structure effectively disperses pressure, buffers external impact, enhances the overall structural strength of the duct, reduces the risk of deformation, extends the service life of the duct, and ensures the long-term stable operation of the ventilation system.

[0052] When inspecting the duct, maintenance personnel can move inside the duct via the sliding grooves on the maintenance track 12, making it easy to reach various locations. The maintenance equipment can also move along the track for comprehensive inspection and repair, which improves the convenience and efficiency of maintenance, allows for timely detection and handling of problems, and ensures the normal operation of the ventilation system.
