Description

Technical Field

[0001] This application relates to the field of duct installation, and in particular to an air conditioning duct installation structure and construction method. Background Technology

[0002] In addition to air conditioning equipment, ventilation ducts are often required in air conditioning rooms to direct the airflow generated by the air conditioning equipment to the outside of the air conditioning room. Most existing ventilation ducts are formed by connecting ducts with rectangular cross-sections. At both ends of the duct in the length direction, external flanges are usually installed, and adjacent ducts are connected by bolts through the external flanges.

[0003] However, this connection method usually involves opening a waist-shaped hole on the outer flange of the duct, so that after the two adjacent ducts are tightened with bolts, they need to be adjusted to ensure that the two adjacent ducts are aligned after installation. In addition, workers need to tighten the bolts on the outer flange one by one, which makes the connection between ducts take a long time, resulting in low connection efficiency between ducts. Summary of the Invention

[0004] In order to improve the connection efficiency between adjacent air ducts, firstly, this application provides an air conditioning air duct installation structure.

[0005] The air conditioning duct installation structure provided in this application adopts the following technical solution: It includes multiple sets of installation components and multiple air ducts. Each installation component is set between two adjacent air ducts. The installation component includes a connecting frame and two hangers. Both hangers are fixedly installed on the ceiling. The connecting frame is located between the two hangers. The ends of the two hangers away from the ceiling are connected to the connecting frame. The connecting frame is provided with insertion slots for air ducts. Two adjacent air ducts can be connected by inserting them into the insertion slots.

[0006] By adopting the above technical solution, two adjacent air ducts can be connected by plugging into the slots on the connecting frame. Subsequently, the position of the connecting frame is fixed by installing it on the hanger, thereby fixing the position of the air duct and realizing the installation of the air duct. Throughout the process, there is no need to connect the two adjacent air ducts with bolts. At the same time, due to the restriction of the air duct's degree of freedom by the plug slot, the time spent tightening bolts and adjusting the position of adjacent air ducts can be saved when connecting the two adjacent air ducts, thus improving the connection efficiency between adjacent air ducts.

[0007] Optionally, the connecting frame includes an inner frame and an outer frame. The inner frame is located inside the outer frame. The hanger is connected to the outer frame. The insertion slot is provided on the inner frame. An elastic element is provided between the outer wall of the inner frame and the inner wall of the outer frame. The elastic element is used to realize the connection between the inner frame and the outer frame.

[0008] By adopting the above technical solution, the connecting frame includes an inner frame and an outer frame, which are connected by an elastic element. The insertion slot is set on the inner frame, which allows two adjacent air ducts to be connected by insertion with the inner frame. This allows the elastic element to buffer the vibration of the air duct when the air duct vibrates due to airflow, thereby achieving the effect of shock absorption.

[0009] Optionally, a connecting block is provided on the outer frame at the position corresponding to the hanger rod. The connecting block is provided with a mounting hole for the hanger rod to pass through. The mounting hole is an oblong hole with the extension direction parallel to the length of the air duct. One end of the hanger rod passing through the mounting hole is connected to a limit nut, which can abut against the connecting block.

[0010] By adopting the above technical solution, a connecting block is provided on the outer frame at the position corresponding to the hanger, and the connecting frame is provided with mounting holes whose extension direction is consistent with the length direction of the air duct. This allows for a certain adjustment space between the outer frame and the hanger, thereby reducing the difficulty of connecting the outer frame and the hanger.

[0011] Optionally, a limit plate is installed on the end of the hanger near the ceiling. The limit plate abuts against the ceiling and has two traction ropes. The ends of the two traction ropes away from the limit plate are respectively connected to two adjacent air ducts that are connected through the inner frame.

[0012] By adopting the above technical solution, the limiting plate is used to limit the depth of the suspension rods inserted into the ceiling, so that the exposed length of each suspension rod after installation on the ceiling can be consistent. The traction rope on the limiting plate is connected to the air duct so that even if the connection between the connecting block and the suspension rod fails, the air duct will not easily fall under the action of the traction rope, thus improving the safety of the computer room.

[0013] Optionally, an adjustment assembly is provided on the inner frame. The adjustment assembly includes a rotating shaft and an adjustment plate. One end of the rotating shaft is located inside the inner frame and is rotatably connected to the inner wall of the inner frame. The other end of the rotating shaft passes through the inner frame and the outer frame and is located outside the outer frame. The rotating shaft can rotate around its own axis. The adjustment plate is fixedly connected to the part of the rotating shaft located inside the inner frame.

[0014] By adopting the above technical solution, the adjustment plate and the rotating shaft are fixedly connected within the inner frame, allowing the operator to adjust the angle of the adjustment plate within the inner frame by driving the rotating shaft to rotate around its own axis, thereby achieving the effect of adjusting the airflow within the duct through the adjustment plate.

[0015] Optionally, an indicator strip is provided on the part of the rotating shaft located outside the outer frame. The length of the indicator strip is perpendicular to the length of the rotating shaft, and the indicator strip and the adjustment plate are in the same vertical plane.

[0016] By adopting the above technical solution, an indicator strip is provided on the part of the rotating shaft located outside the outer frame, and the indicator strip and the adjustment plate are in the same vertical plane. This allows the staff to know the rotation angle of the adjustment plate in the inner frame according to the adjustment rod, which facilitates the staff to adjust the airflow in the duct.

[0017] Optionally, an annular groove is provided on the side of the outer frame near the indicator strip. The annular groove is a C-shaped groove. A limit block is provided in the annular groove. Limit bolts are respectively passed through both ends of the indicator strip. One end of the limit bolt passes through the indicator strip and is connected to the limit block by a threaded engagement. The other end of the limit bolt can abut against the indicator strip.

[0018] By adopting the above technical solution, when it is necessary to fix the rotation angle of the adjustment plate, the limit block is pressed against the inner wall of the annular groove by tightening the limit bolt, thereby restricting the rotation of the shaft around its own axis and thus achieving the effect of limiting the rotation angle of the adjustment plate.

[0019] Secondly, this application also provides a construction method for an air conditioning duct installation structure, which adopts the above-mentioned air conditioning duct installation structure and includes the following steps: S100: Fix the hangers to the target positions on the ceiling and pre-install each duct on the ground using the connecting frame; S200: Move all the connected air ducts and connecting frames to below the hanger, and then lift all the air ducts to connect the hanger and the connecting frame; S300: Perform an airtightness check on the connections of each duct.

[0020] In summary, this application includes at least the following beneficial technical effects: 1. By setting insertion slots on the inner frame for inserting the ends of the air ducts, adjacent air ducts can be connected by inserting into the inner frame. This eliminates the need for bolts to connect adjacent air ducts. Furthermore, the insertion slots restrict the freedom of the air ducts, saving time spent tightening bolts and adjusting the position of adjacent air ducts during connection, thus improving the connection efficiency between adjacent air ducts.

[0021] 2. By rotating the drive shaft around its own axis, the angle of the adjusting plate within the inner frame can be changed, thereby achieving the effect of adjusting the airflow within the duct through the adjusting plate. Attached Figure Description

[0024] The following is in conjunction with the appendix Figure 1-6 This application will be described in further detail.

[0025] Example 1 Embodiment 1 of this application discloses an air conditioning duct installation structure, referring to... Figure 1 , Figure 2 and Figure 3 The system includes multiple sets of installation components 1 and multiple air ducts 2. In this embodiment 1, there are three sets of installation components 1 and two air ducts 2. The three sets of installation components 1 and the two air ducts 2 are arranged alternately. Each set of installation components 1 includes a connecting frame 3 and two hangers 4. The connecting frame 3 is rectangular. The upper ends of the two hangers 4 are fixed on the ceiling in the air conditioning room. The connecting frame 3 is located between the two hangers 4 and connected to the two hangers 4. Insertion slots 5 for inserting the ends of the air ducts 2 are respectively provided on the front and back sides of the connecting frame 3. This allows two adjacent air ducts 2 to be connected by inserting them into the insertion slots 5 on the connecting frame 3.

[0026] Furthermore, a sealing gasket can be installed on the inner wall of the insertion slot 5, which will improve the sealing performance when the air duct 2 is inserted into the insertion slot 5 and reduce the possibility of airflow leakage after two adjacent air ducts 2 are connected.

[0027] The connecting frame 3 includes an outer frame 7 and an inner frame 6. The outer frame 7 and the inner frame 6 are connected by an elastic element 8. The elastic element 8 is a rubber block. One end of the elastic element 8 is connected to the inner wall of the outer frame 7, and the other end of the elastic element 8 is connected to the outer wall of the inner frame 6. The insertion groove 5 is provided on the inner frame 6. This means that when the air duct 2 is inserted into the insertion groove 5 on the inner frame 6, even if the air duct 2 vibrates due to airflow transmission during operation, the elastic element 8 can buffer and absorb the vibration of the air duct 2.

[0028] In other embodiments, the elastic element 8 can also be a spring, which is distributed between the outer frame 7 and the inner frame 6, with one end of the spring connected to the inner wall of the outer frame 7 and the other end of the spring connected to the outer wall of the inner frame 6.

[0029] At the location of the hanger rod 4 on the outer wall of the outer frame 7, there is a connecting block 9. The connecting block 9 has a mounting hole 10. The mounting hole 10 is an oblong hole with the extension direction consistent with the length direction of the air duct 2. The end of the hanger rod 4 away from the ceiling passes through the mounting hole 10 and is connected to a limit nut 11. The limit nut 11 is an anti-loosening nut. The limit nut 11 supports the connecting block 9 by abutting against the lower surface of the connecting block 9, so that the connecting block 9 will not easily come off the hanger rod.

[0030] In other embodiments, the connecting block 9 can be slidably mounted on the outer frame 7 so that the connecting block 9 can slide along the length direction of the air duct 2 on the outer frame 7. In this case, the mounting hole 10 on the connecting block 9 is an oblong hole with the extension direction perpendicular to the length direction of the air duct 2, thereby further reducing the accuracy requirements when the connecting block 9 is connected to the hanger 4.

[0031] Furthermore, a limiting plate 12 is provided at the end of the hanger 4 near the ceiling. The limiting plate 12 is fixedly installed on the hanger 4. When the end of the hanger 4 is connected to the bolt sleeve pre-embedded in the ceiling, the limiting plate 12 can be pressed against the surface of the ceiling. This allows the length of the part of the hanger 4 outside the ceiling to remain consistent, so that the horizontality of the duct 2 can be initially adjusted based on the length of the hanger 4.

[0032] Two traction ropes 13 are also provided on the limiting plate 12. The traction ropes 13 are steel wire ropes. One end of the traction rope 13 is connected to the limiting plate 12, and the other end of the traction rope 13 is connected to the outer wall of the air duct 2. The two traction ropes 13 enable the limiting plate 12 to connect the air duct 2 at the front and rear ends of the inner frame 6 respectively. Thus, when the limiting nut 11 loosens and the connection between the connecting block 9 and the hanger 4 fails, the traction rope 13 can still pull the air duct 2 to keep it horizontal, thereby reducing the risk of the air duct 2 falling off the hanger 4.

[0033] Reference Figure 4, Figure 5 and Figure 6 An adjustment assembly 14 is also provided on the inner frame 6. The adjustment assembly 14 includes a rotating shaft 15 and an adjustment plate 16. One end of the rotating shaft 15 is vertically connected to the inner wall of the inner frame 6, and the other end of the rotating shaft 15 passes through the inner frame 6 and the outer frame 7 and is located outside the outer frame 7. The rotating shaft 15 can rotate around its own axis, while the adjustment plate 16 is located inside the inner frame 6 and fixedly connected to the rotating shaft 15. This allows the adjustment plate 16 to rotate with the rotating shaft 15 when the rotating shaft 15 rotates around its own axis, thereby enabling adjustment. Plate 16 can adjust the airflow rate in duct 2. When plate 16 is perpendicular to the length of duct 2, plate 16 intercepts the airflow in duct 2 with the maximum area, which reduces the airflow rate from the current duct 2 to the next duct 2 to the minimum. When plate 16 is rotated to be parallel to the length of duct 2 under the action of shaft 15, plate 16 intercepts the airflow in duct 2 with the minimum area, which increases the airflow rate from the current duct 2 to the next duct 2 to the maximum.

[0034] An indicator strip 17 is also provided on the part of the rotating shaft 15 located outside the outer frame 7. The axis of the indicator strip 17 is perpendicular to the axis of the rotating shaft 15, and the axis of the indicator strip 17 is in the same plane as the adjusting plate 16. This allows the operator to determine the position of the adjusting plate 16 in the inner frame 6 by the angle between the indicator strip 17 and the length direction of the air duct 2, which facilitates the operator to adjust the airflow in the air duct 2. On the other hand, it also allows the operator to rotate the rotating shaft 15 by moving the indicator strip 17, thereby reducing the difficulty of rotating the rotating shaft 15.

[0035] Furthermore, an annular groove 18 is provided on the side of the outer frame 7 near the indicator strip 17. The annular groove 18 is a C-shaped groove, and two limiting blocks 19 are provided in the annular groove 18. The limiting blocks 19 have a circular cross-section, which allows the limiting blocks 19 to slide within the annular groove 18. At each end of the indicator strip 17, a limiting bolt 20 is respectively inserted. The axis of the limiting bolt 20 is parallel to the axis of the rotating shaft 15. After passing through the end of the indicator strip 17, one end of each limiting bolt 20 engages with the limiting block 19 in the annular groove 18 through a threaded connection. The two limit bolts 20 are connected, and the other ends of the two limit bolts 20 are abutted against the outer wall of the indicator strip 17. This means that when the angle of the rotating shaft 15 needs to be fixed, the limit block 19 can be pressed against the inner wall of the annular groove 18 by tightening the two limit bolts 20 respectively, so that the angle of the adjusting plate 16 in the inner frame 6 will not easily change. When the angle of the adjusting plate 16 in the inner frame 6 needs to be changed, the angle of the adjusting plate 16 can also be changed by loosening the limit bolts 20 and then driving the rotating shaft 15 to rotate around its own axis.

[0036] The implementation principle of this application embodiment is as follows: First, the hanger rods 4 are fixed to the ceiling in sequence so that the upper limit plate 12 of the hanger rods 4 abuts against the surface of the ceiling. Then, two adjacent air ducts 2 are connected by the connecting frame 3. After each air duct 2 is assembled to the corresponding length by the connecting frame 3, the connecting block 9 on the connecting frame 3 is connected to the hanger rods 4 by lifting the whole assembly. Then, the height of the connecting frame 3 is adjusted by adjusting the limit nut 11 so that the connecting frames 3 at both ends of the air duct 2 are at the same height. Finally, the traction rope 13 is tightened so that the traction rope 13 is connected to the outer wall of the air duct 2.

[0037] Example 2 Embodiment 2 of this application provides a construction method for an air conditioning duct installation structure, which adopts an air conditioning duct installation structure from Embodiment 1 above, and includes the following steps: S100: Fix the hangers 4 to the target positions on the ceiling respectively, and pre-install each air duct 2 on the ground through the connecting frame 3; S200: Move all the connected air ducts 2 and the connecting frame 3 to below the hanger 4, and then lift all the air ducts 2 so that the hanger 4 and the connecting frame 3 are connected; S300: After tightening the traction rope 13 on the limit block 19, connect it to the side wall of the air duct 2; S400: Perform an airtightness check on the connections of each duct 2.

[0038] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
