Description

Technical Field

[0001] This invention relates to the field of air conditioning duct installation technology, and in particular to a stabilizing device for air conditioning system ducts. Background Technology

[0002] Air conditioning duct systems use air as the transport medium, and their principle is basically the same as that of central air conditioning systems. Air conditioning duct systems utilize the cooling and heating generated centrally by the air conditioning unit to centrally process the return air from the room, and then send it into the room through ducts.

[0003] Currently, air conditioning system ducts are mainly suspended and installed using hangers and expansion bolts. The hangers support the lower end of the duct. However, this method has the following disadvantages: on the one hand, the contact area between a single hanger and the duct is limited; on the other hand, the expansion bolts are prone to shaking after long-term use, resulting in poor installation stability of the duct.

[0004] A search revealed Chinese patent CN207701925U, which discloses an installation structure for air conditioning ducts. This structure solves the problem of unstable installation caused by ducts being easily shaken under strong winds and vibrations when suspended from the roof using common methods. The key technical features include: multiple hangers fixed to the roof; multiple mounting base plates fixed between two of the hangers and located at the ends of the hangers furthest from the roof; a support plate on the mounting base plate; a duct body on the support plate; and an installation assembly on the support plate for fixing the duct body, thus achieving a more stable installation of the duct body.

[0005] However, the above-mentioned patent has the following shortcomings: Although the above-mentioned patent ensures the contact between the installation structure and the air duct by setting the installation components, in actual use, it still relies solely on the connection and fixation between the hanger and the roof. This results in a small force point for the air duct, and the connection point at the top of the hanger is still a relatively weak position, which is prone to loosening and shaking, thus affecting the overall installation stability of the air duct. Summary of the Invention

[0006] The purpose of this invention is to provide a stabilizing device for air conditioning system ducts to solve the problems mentioned in the background art.

[0007] The technical solution of the present invention is: a stabilizing device for air conditioning system ducts, comprising multiple mounting plates and multiple sets of clamp assemblies. The multiple mounting plates are fixed to the top of the floor. The clamp assemblies are used to fix the ducts. Each set of clamp assemblies includes a first clamp bracket and a second clamp bracket of the same specifications. Both the first clamp bracket and the second clamp bracket are C-shaped. Each first clamp bracket has a drive rod and two side rods rotatably mounted on it. The ends of the drive rod and the two side rods are provided with threaded ends. One side of the second clamp bracket has multiple threaded mating holes that match the threaded ends.

[0008] Each mounting plate has a sliding groove on its bottom outer wall, and an adjusting hanging plate is slidably connected to both sides of the sliding groove. Each adjusting hanging plate has an integral hook plate at its bottom end, and the top of the first and second brackets has a hook end that matches the hook plate.

[0009] Side end blocks are fixedly installed on the opposite outer walls of both the first and second brackets. Each side end block has an arc-shaped end rod rotatably mounted on its top via a movable shaft, and a triangular connecting block is rotatably mounted on the other end of each arc-shaped end rod via a movable shaft. A locking rod is rotatably mounted on the outer wall of the triangular connecting block away from the arc-shaped end rod. Each adjusting plate has a strip-shaped slot, the width of which is greater than the width of the locking rod. Both ends of the locking rod are threaded with abutment bolts. After the duct is initially fixed, the arc-shaped end rod can be moved upwards, and the locking rod adjusted to be parallel to the wide side of the triangular connecting block. When the triangular connecting block abuts against the strip-shaped slot, the locking rod can pass through the slot. At this point, the locking rod is rotated 90 degrees so that it is perpendicular to the strip-shaped slot. After this, the abutment bolts are rotated to make the locking rod tightly abut against the adjusting plate, further reinforcing the duct connection structure.

[0010] Preferably, each mounting plate has mounting vertical rods fixed on both sides of its bottom outer wall, and the two mounting vertical rods are rotatably mounted with the same screw rod. A polygonal cavity end cylinder is fixedly mounted on the opposite outer wall of the two mounting vertical rods, and a threaded end rotating rod is rotatably mounted on the top of each polygonal cavity end cylinder. The bottom of each threaded end rotating rod is connected to a threaded cavity tube by a thread, and a polygonal piston plate that slides and engages with the inner wall of the polygonal cavity end cylinder is fixedly mounted at the bottom end of each threaded cavity tube.

[0011] Preferably, each of the threaded end rotating rods and the screw rods is keyed with meshing transmission conical teeth, and a return spring is fixedly installed inside the bottom end of each of the polygonal cavity end cylinders. The bottom end of each return spring is fixedly installed with a sliding abutment plate that slides against the inner wall of the polygonal cavity end cylinder. Hydraulic oil is filled between the polygonal piston plate and the abutment plate.

[0012] Preferably, each of the side end blocks has two vertically distributed through holes, and a connecting horizontal shaft is inserted into two adjacent side end blocks. The two adjacent connecting horizontal shafts are staggered vertically. Both ends of each connecting horizontal shaft are connected to a fastening nut by thread, and each connecting horizontal shaft has a lifting lug fixedly connected to both sides near the end.

[0013] Preferably, each of the screw rods is fixedly installed with grooved wheels on both sides near its end, and each grooved wheel is bolted with two elastic suspension ropes, the ends of which are fixedly connected to the lifting lugs.

[0014] After the duct is installed and fixed, the screw rod can be rotated. Through the transmission of the bevel gear, the threaded end rod rotates. Since the multi-sided cavity end cylinder can limit the multi-sided piston plate, the threaded cavity tube can move downward along with the multi-sided piston plate. Through the transmission of hydraulic oil, it pushes the abutment plate downward, thereby applying a resisting force to the top of the duct, making the duct in close contact with the first and second brackets, which helps to further improve the stability of the duct fixing. Before rotating the screw rod, the end of the elastic suspension rope can be fixed to the lifting lug. Thus, when the screw rod is rotated, it can drive the grooved wheel to rotate and retract the corresponding elastic suspension rope. This can improve the support effect on the duct with the help of the connecting horizontal shaft, ensuring that the duct maintains a good and stable state during use.

[0015] Preferably, one end of the screw rod is fixedly mounted with an end plate, and the end plate has a plurality of equally spaced annularly distributed adjustment holes near its edge. The mounting plate has a locking hole near the end plate, and a locking rod is inserted between the locking hole and the opposite adjustment hole.

[0016] Preferably, a rubber clamping roller is fixedly sleeved at the middle end of each of the connecting horizontal shafts.

[0017] Preferably, the end of the drive rod away from the threaded end passes through the first bracket, and the drive rod and the two adjacent side rods are all fixedly installed with transmission gears of the same specification, and the two adjacent transmission gears mesh with each other.

[0018] Preferably, one end of each of the two opposing hook plates is connected to a pull rod by a thread, and both ends of the pull rod are connected to abutment nuts by a thread.

[0019] Preferably, both the first and second brackets are fixedly installed with extended side columns at the top corners.

[0020] This invention, by improving the stabilizing device for air conditioning system ducts, has the following improvements and advantages compared to the prior art:

[0021] Firstly, this invention utilizes the threaded ends located at the ends of the drive rod and the two side rods to facilitate connection with the threaded mating holes on the second bracket, thereby splicing the first and second brackets to achieve the encirclement and support of the bottom side of the duct, thus fixing the duct. Moving the adjusting plate allows it to align with the end of the hook, and by translating the first and second brackets, the end of the hook can be made to fit with the hook plate, thereby achieving the connection and fixation of the adjusting plate with the first and second brackets, thus achieving the initial fixation of the duct.

[0022] Secondly, after the duct is initially fixed, the arc-shaped end rod can be moved upward and the locking rod can be adjusted to be parallel to the wide side of the triangular connecting block. When the triangular connecting block abuts against the strip groove, the locking rod can pass through the strip groove. At this time, the locking rod is rotated ninety degrees so that the locking rod and the strip groove are perpendicular to each other. After completion, the abutment bolt is rotated to make the locking rod abut tightly against the adjusting plate, so as to further strengthen the duct connection structure.

[0023] Thirdly, after the duct is installed and fixed, the rotating rod can be rotated. Through the transmission of the bevel gear, the threaded end rod rotates. Since the multi-sided cavity end cylinder can limit the multi-sided piston plate, the threaded cavity tube can move downward along with the multi-sided piston plate. Through the transmission of hydraulic oil, it pushes the abutment plate downward, thereby applying a resisting force to the top of the duct, making the duct in close contact with the first and second brackets, which helps to further improve the stability of the duct fixing. Before rotating the rotating rod, the end of the elastic suspension rope can be fixed to the lifting lug. Thus, when rotating the rotating rod, the grooved wheel can be driven to rotate, and the corresponding elastic suspension rope can be retracted. This can improve the support effect on the duct with the help of the connecting horizontal shaft, ensuring that the duct can maintain a good and stable state during use. Attached Figure Description

[0036] The present invention will now be described in detail, and the technical solutions in the embodiments of the present invention will be clearly and completely described. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0037] This invention provides an improved device for stabilizing air conditioning system ducts. The technical solution of this invention is as follows:

[0038] like Figures 1 to 9As shown, this embodiment of the invention provides a stabilizing device for an air conditioning system duct, including multiple mounting plates 5 and multiple sets of clamp assemblies. The mounting plates 5 are fixed to the top of the floor, and the clamp assemblies are used to fix the duct. Each set of clamp assemblies includes a first clamp bracket 1 and a second clamp bracket 14 of the same specifications. Both the first clamp bracket 1 and the second clamp bracket 14 are C-shaped. Each first clamp bracket 1 has a drive rod 11 and two side rods 111 rotatably mounted on it, and the ends of the drive rod 11 and the two side rods 111 are provided with threaded ends 112. One side of the second clamp bracket 14 has multiple threaded mating holes 141 that match the threaded ends 112. Through the above structure, the threaded ends 112 provided at the ends of the drive rod 11 and the two side rods 111 can be easily connected to the threaded mating holes 141 on the second clamp bracket 14, thereby splicing the first clamp bracket 1 and the second clamp bracket 14 to achieve the encirclement and support of the bottom side of the duct and to fix the duct.

[0039] Each mounting plate 5 has a groove 51 on its bottom outer wall, and an adjusting hanging plate 3 is slidably connected to both sides of the groove 51. Each adjusting hanging plate 3 has an integral hook plate 33 at its bottom end. The top of the first bracket 1 and the second bracket 14 are provided with hook ends 15 that are adapted to the hook plates 33. With the above structure, when in use, the mounting plate 5 can be fixed first, and the adjusting hanging plate 3 can be moved so that the adjusting hanging plate 3 is aligned with the hook end 15. By translating the first bracket 1 and the second bracket 14, the hook end 15 is made to fit with the hook plate 33, so as to realize the connection and fixation of the adjusting hanging plate 3 with the first bracket 1 and the second bracket 14, thereby realizing the initial fixation of the air duct.

[0040] Side end blocks 13 are fixedly installed on the opposite outer walls of both bracket 1 and bracket 2 14. Each side end block 13 has an arc-shaped end rod 31 rotatably mounted on its top via a movable shaft. The other end of each arc-shaped end rod 31 is rotatably mounted with a triangular connecting block 313 via a movable shaft. A locking rod 311 is rotatably mounted on the outer wall of the triangular connecting block 313 away from the arc-shaped end rod 31. Each adjusting plate 3 has a strip-shaped slot 301, the width of which is greater than the width of the locking rod 311. Both ends of the locking rod 311 are threadedly connected with abutment bolts 312. With the above structure, after the duct is initially fixed, the arc-shaped end rod 31 can be moved upward and the locking rod 311 can be adjusted to be parallel to the wide side of the triangular connecting block 313. When the triangular connecting block 313 abuts against the strip groove 301, the locking rod 311 can pass through the strip groove 301. At this time, the locking rod 311 is rotated ninety degrees so that the locking rod 311 and the strip groove 301 are perpendicular to each other. After completion, the locking rod 311 is tightly abutted against the adjusting plate 3 by rotating the abutment bolt 312, so as to further strengthen the duct connection structure.

[0041] As a further embodiment of the present invention, each mounting plate 5 has a mounting vertical rod 62 fixed on both sides of its bottom outer wall, and the two mounting vertical rods 62 are rotatably mounted with the same screw rod 6. The opposite sides of the outer walls of the two mounting vertical rods 62 are fixedly mounted with polygonal cavity end cylinders 2, and the top of each polygonal cavity end cylinder 2 is rotatably mounted with a threaded end rotating rod 63. The bottom of each threaded end rotating rod 63 is connected to a threaded cavity tube 22 by a thread, and the bottom end of each threaded cavity tube 22 is fixedly mounted with a polygonal piston plate 24 that slides in cooperation with the inner wall of the polygonal cavity end cylinder 2.

[0042] Furthermore, each threaded end rotating rod 63 and the screw rod 6 are keyed together with meshing transmission bevel teeth 61. A return spring 23 is fixedly installed inside the bottom end of each polygonal cavity end cylinder 2, and a stop plate 21 that slides with the inner wall of the polygonal cavity end cylinder 2 is fixedly installed at the bottom end of each return spring 23. Hydraulic oil is filled between the polygonal piston plate 24 and the stop plate 21. The return spring 23 facilitates the subsequent reset of the stop plate 21 when the polygonal piston plate 24 moves upward.

[0043] With the above structure, after the duct is installed and fixed, the rotating rod 6 can be rotated. Through the transmission action of the transmission bevel gear 61, the threaded end rotating rod 63 is driven to rotate. Since the polygonal cavity end cylinder 2 can limit the polygonal piston plate 24, the threaded cavity tube 22 can move downward together with the polygonal piston plate 24. Through the transmission action of hydraulic oil, it pushes the abutment plate 21 to move downward, thereby applying a resisting force to the top of the duct, so that the duct is in close contact with the first bracket 1 and the second bracket 14, which helps to further improve the stability of the duct fixing.

[0044] Furthermore, each side end block 13 has two vertically distributed through holes 131, and a connecting horizontal shaft 4 is inserted into two adjacent side end blocks 13. The two adjacent connecting horizontal shafts 4 are staggered vertically. Both ends of each connecting horizontal shaft 4 are connected to a fastening nut 41 by thread, and each connecting horizontal shaft 4 is fixedly connected to two sides near the end.

[0045] The above structure, with its connecting horizontal axis 4, can improve the overall integrity of adjacent bracket 1 and bracket 2 14, thereby improving the stability of multi-section duct connections and effectively reducing wind noise caused by structural instability.

[0046] Furthermore, each screw rod 6 has a grooved wheel 64 fixedly installed on both sides near its end, and each grooved wheel 64 has two elastic suspension ropes 44 bolted inside, with the ends of the elastic suspension ropes 44 fixedly connected to the lifting lugs 43.

[0047] With the above structure, before rotating the screw rod 6, the end of the elastic suspension rope 44 can be fixed to the lifting lug 43. Thus, when rotating the screw rod 6, the groove wheel 64 can be driven to rotate, and the corresponding elastic suspension rope 44 can be retracted. This can improve the support effect on the air duct with the help of the connecting horizontal shaft 4, and ensure that the air duct can maintain a good and stable state during use.

[0048] As a further embodiment of the present invention, an end plate 65 is fixedly installed at one end of the screw rod 6, and a plurality of equally spaced annularly distributed adjustment holes 66 are provided near the edge of the end plate 65. A locking insertion hole is provided at the end of the mounting plate 5 near the end plate 65, and a locking rod 67 is inserted between the locking insertion hole and the corresponding adjustment hole 66. With the above structure, after the screw rod 6 rotates to complete the pressing and fixing of the air duct, it can be finely adjusted so that one of the adjustment holes 66 is aligned with the locking insertion hole on the mounting plate 5. Finally, the locking rod 67 is inserted into the locking insertion hole through the corresponding adjustment hole 66 to lock the screw rod 6, thereby preventing the screw rod 6 from rotating due to the force applied, which would weaken the fixing effect on the air duct.

[0049] Furthermore, a rubber clamping roller 42 is fixedly sleeved at the middle end of each connecting horizontal shaft 4; through the above structure, after the connecting horizontal shaft 4 is installed, the rubber clamping roller 42 can be used to abut against the weak connection between two adjacent air ducts, thereby further improving the reinforcement of the air duct structure.

[0050] As a further embodiment of the present invention, the end of the drive rod 11 away from the threaded end 112 passes through the first bracket 1. The drive rod 11 and the two adjacent side rods 111 are all fixedly mounted with transmission gears 113 of the same specification, and the two adjacent transmission gears 113 mesh with each other. With the above structure, when splicing the first bracket 1 and the second bracket 14, one end of the drive rod 11 can be rotated. After the transmission action of multiple transmission gears 113, the two side rods 111 can rotate synchronously, so that the threaded end 112 can be quickly screwed and fixed with the threaded mating hole 141.

[0051] As a further embodiment of the present invention, one end of each of the two opposing hook plates 33 is threadedly connected to a pull rod 32, and both ends of the pull rod 32 are threadedly connected to abutment nuts 321. With the above structure, when the adjusting plate 3 is moved so that the hook end 15 is engaged with the hook plate 33, the pull rod 32 can be installed and fixed by the abutment nuts 321. The pull rod 32 can fix the position of the two adjusting plates 3 on the one hand, and limit the hook end 15 on the other hand, preventing the hook end 15 from separating from the hook plate 33, thereby ensuring the reliability of the duct fixing.

[0052] Furthermore, both the first bracket 1 and the second bracket 14 are fixedly installed with extension side columns 12 on both sides of the top corner; through the above structure, the extension side columns 12 can guide the elastic suspension rope 44 to avoid friction damage between the elastic suspension rope 44 and the edge of the air duct.

[0053] The specific working method is as follows: First, fix the mounting plate 5 to the top of the floor. Then, clip the first bracket 1 and the second bracket 14 onto one side of the duct. Move the adjusting plate 3 on the mounting plate 5 until it aligns with the hook end 15. By translating the first bracket 1 and the second bracket 14, the hook end 15 engages with the hook plate 33, thus achieving the connection and fixation of the adjusting plate 3 with the first and second brackets 14, thereby achieving initial fixation of the duct. Next, rotate one end of the drive rod 11. After transmission through multiple gears 113, the two sides... The rotating rod 111 rotates synchronously, allowing the threaded end 112 to be quickly screwed and fixed to the threaded mating hole 141. This splices the first and second brackets 14, providing support and enclosure for the bottom of the duct, thus securing the duct. After initial duct fixation, the arc-shaped end rod 31 can be moved upwards, and the locking rod 311 can be adjusted to be parallel to the wide side of the triangular connecting block 313. When the triangular connecting block 313 abuts against the strip groove 301, the locking rod 311 can pass through the strip groove 301. At this point, rotating the locking rod 311 ninety degrees further locks the duct. The rotating rod 311 and the strip slot 301 are perpendicular to each other. After completion, the locking rotating rod 311 and the adjusting hanging plate 3 are tightly abutted by rotating the abutment bolt 312 to further reinforce the duct connection structure. Connecting horizontal shafts 4 are inserted into the two adjacent side end blocks 13 and fixed by fastening nuts 41. The connecting horizontal shafts 4 can improve the integrity of the adjacent bracket 1 and bracket 2 14, thereby improving the firmness of the multi-section duct connection. The end of the elastic hanging rope 44 is fixed to the lifting lug 43. The rotating rod 6 drives the groove wheel 64 to rotate and the phase The elastic suspension rope 44 is retracted, thereby improving the support effect on the duct with the help of the connecting horizontal shaft 4; when the screw rod 6 rotates, it drives the threaded end rotating rod 63 to rotate through the transmission action of the transmission bevel gear 61. Since the polygonal cavity end cylinder 2 can limit the polygonal piston plate 24, the threaded cavity tube 22 can move downward together with the polygonal piston plate 24, and through the transmission action of hydraulic oil, push the abutment plate 21 to move downward, thereby applying a resisting force to the top of the duct, so that the duct is in close contact with the first bracket 1 and the second bracket 14, which helps to further improve the stability of the duct fixing.

[0054] In summary, this invention, through the cooperation and assistance of various fixing methods, can effectively improve the robustness of multi-section air duct connections and effectively reduce the significant wind noise caused by structural instability.

Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the invention. Therefore, the invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
