Description

Technical Field

[0001] This utility model relates to the field of seismic-resistant supports for air ducts, and in particular to a bidirectional seismic-resistant support for air ducts. Background Technology

[0002] Seismic bracing for ductwork is an important support device used to fix ventilation ducts, air conditioning ducts and other equipment. Its core working principle is to offset the impact of seismic loads such as earthquakes on the ductwork through the elastic deformation, damping buffer or rigid constraint of the mechanical structure, so as to prevent the ductwork from falling off, displacing or being damaged, and to ensure the safety and stability of the ventilation system in the vibration environment.

[0003] In existing duct support designs, most seismic-resistant components are only installed on one side of the duct body, and the force transmission path of the internal seismic components is fixed and singular, making it difficult to effectively cope with complex working conditions of multi-directional vibration superposition, thus limiting seismic adaptability. Secondly, the existing bidirectional seismic-resistant structures of the supports are mostly in an independent working state, lacking the necessary linkage mechanism. For example, when the upper seismic-resistant components absorb vertical vibration through spring extension and contraction, the lower structure cannot synchronously adjust its stress state to assist in stress relief, resulting in the inability to fully exert the synergistic damping effect of each component. Under strong earthquake conditions, the protection effect on the duct will be greatly weakened. To solve the above problems, we propose a bidirectional seismic-resistant duct support. Utility Model Content

[0004] The main purpose of this utility model is to provide a bidirectional seismic-resistant support for air ducts, which can effectively solve the problems in the background art.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A bidirectional seismic-resistant duct support includes a seismic-resistant support housing. A duct storage rack is slidably connected to the inner side of the seismic-resistant support housing. A first seismic-resistant component is provided at the upper end of the duct storage rack. The first seismic-resistant component includes a first rotating upright plate and a second rotating upright plate. Both the first and second rotating upright plates are rotatably connected to the upper end of the duct storage rack, and a tension component is provided between the first and second rotating upright plates. A second seismic-resistant component is provided at the lower end of the duct storage rack. The second seismic-resistant component includes a first lower rotating round rod and a second lower rotating round rod. The first and second lower rotating round rods are rotatably connected to a connecting seat, and the connecting seat is fixedly connected to the lower end of the duct storage rack.

[0007] Preferably, the first seismic component further includes a buffer cylinder, which is fixedly connected to the upper inner side of the seismic support shell. A pull rod is slidably connected to the inner side of the buffer cylinder, and a lifting block is fixedly connected to the lower end of the pull rod. A first upper rotating rod and a second upper rotating rod are rotatably connected to both sides of the lifting block, respectively. The other end of the first upper rotating rod is rotatably connected to the first rotating upright plate, and the other end of the second upper rotating rod is rotatably connected to the second rotating upright plate.

[0008] Preferably, a circular plate is fixedly connected to the upper end of the pull rod, the circular plate is slidably connected to the inner side of the buffer cylinder, and a first tension spring is sleeved on the outer side of the pull rod, with the upper and lower ends of the first tension spring being fixedly connected to the circular plate and the buffer cylinder, respectively.

[0009] Preferably, the tension assembly includes a telescopic column, with two ends of the telescopic column movably connected to second tension springs, and the two second tension springs being fixedly connected to the corresponding first rotating plate and second rotating plate, respectively. A movable bracket is sleeved on the outer side of the telescopic column, and the two ends of the movable bracket are fixedly connected to the first rotating plate and the second rotating plate, respectively.

[0010] Preferably, the lower ends of the first and second lower rotating round rods are rotatably connected to sliding sleeves, and the inner sides of the two sliding sleeves are slidably connected to guide rods. The guide rods are fixedly connected to the outer shell of the seismic brace. The ends of the two sliding sleeves that are far apart are fixedly connected to third tension springs sleeved on the outside of the guide rods, and the other ends of the two third tension springs are fixedly connected to the outer shell of the seismic brace.

[0011] Preferably, two cylinders are fixedly installed on the lower inner side of the duct storage rack, and the output ends of the two cylinders are fixedly connected to a clamping plate. Sliders are fixedly connected to both sides of the clamping plate. Two sliding grooves corresponding to the sliders are opened on both sides of the inner wall of the duct storage rack, and the sliders are slidably connected to the inner side of the sliding grooves.

[0012] Preferably, guide rails are fixedly connected to both sides of the duct storage rack, and two guide grooves corresponding to the guide rails are opened on both sides of the inner wall of the seismic support shell, and the guide rails are slidably connected to the inner side of the guide grooves.

[0013] Preferably, the upper end of the inner wall of the air duct storage rack and the upper end of the clamping plate are both provided with anti-slip textures.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] 1. This bidirectional seismic bracing for ducts, when encountering multi-directional vibrations, the upper first seismic component, through the linkage of the first rotating vertical plate, the second rotating vertical plate, the first upper rotating rod, and the second upper rotating rod, transmits the vertical vibration energy to the first tension spring inside the buffer cylinder. The energy is absorbed through the expansion and contraction of the spring. At the same time, the lower second seismic component, through the first lower rotating rod and the second lower rotating rod, drives the sliding sleeve block to slide on the guide rod. Combined with the deformation of the third tension spring, it offsets the combined horizontal and vertical vibration impacts. It can adapt to multi-directional vibration superposition scenarios under complex working conditions, and greatly improves the seismic resistance.

[0016] 2. In this bidirectional seismic bracing for ductwork, when the first and second rotating vertical plates in the upper first seismic component rotate, the tension component will synchronously adjust the stress state of the two, ensuring that the upper seismic structure always maintains an efficient buffer posture. At the same time, the displacement of the duct storage rack will synchronously drive the sliding sleeve of the lower second seismic component to compress or stretch the third tension spring, so that the upper and lower seismic components form a linkage during the unloading process, which can better ensure the safety and stability of the ductwork.

[0023] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0024] like Figure 1-5 As shown, a bidirectional seismic-resistant duct support includes a seismic-resistant support housing 1. A duct storage rack 2 is slidably connected to the inner side of the seismic-resistant support housing 1. A first seismic-resistant component is provided at the upper end of the duct storage rack 2. The first seismic-resistant component includes a first rotating upright plate 5 and a second rotating upright plate 6. Both the first rotating upright plate 5 and the second rotating upright plate 6 are rotatably connected to the upper end of the duct storage rack 2, and a tension component is provided between the first rotating upright plate 5 and the second rotating upright plate 6. A second seismic-resistant component is provided at the lower end of the duct storage rack 2. The second seismic-resistant component includes a first lower rotating round rod 22 and a second lower rotating round rod 23. The first lower rotating round rod 22 and the second lower rotating round rod 23 are rotatably connected to a connecting seat 21. The connecting seat 21 is fixedly connected to the lower end of the duct storage rack 2. Guide rails 3 are fixedly connected to both sides of the duct storage rack 2. Two guide grooves 4 corresponding to the guide rails 3 are opened on both sides of the inner wall of the seismic-resistant support housing 1. The guide rails 3 are slidably connected to the inner side of the guide grooves 4.

[0025] In this embodiment, the first anti-seismic component further includes a buffer cylinder 10, which is fixedly connected to the upper inner side of the outer shell 1 of the anti-seismic bracket. A pull rod 12 is slidably connected to the inner side of the buffer cylinder 10. A lifting block 9 is fixedly connected to the lower end of the pull rod 12. A first upper rotating rod 7 and a second upper rotating rod 8 are rotatably connected to both sides of the lifting block 9, respectively. The other end of the first upper rotating rod 7 is rotatably connected to the first rotating upright plate 5, and the other end of the second upper rotating rod 8 is rotatably connected to the second rotating upright plate 6. A circular plate 11 is fixedly connected to the upper end of the pull rod 12. The circular plate 11 is slidably connected to the inner side of the buffer cylinder 10. A first tension spring 13 is sleeved on the outer side of the pull rod 12. The upper and lower ends of the first tension spring 13 are fixedly connected to the circular plate 11 and the buffer cylinder 10, respectively.

[0026] Specifically, when encountering vibration, the duct body will move due to inertia, causing the duct holding rack 2 to move. By sliding within the guide groove 4 on the inner wall of the anti-vibration bracket shell 1 through the guide rails 3 on both sides, the stability of the duct holding rack 2 during movement can be improved. When the duct holding rack 2 moves, it will drive the first rotating plate 5 and the second rotating plate 6 to rotate. Through the rotational cooperation of the first upper rotating round rod 7 and the second upper rotating round rod 8, the lifting block 9 can be driven to move up and down, causing the pull rod 12 to slide within the buffer cylinder 10. The sliding of the pull rod 12 will cause the round plate 11 to compress or stretch the first tension spring 13 to absorb the vertical vibration energy.

[0027] In this embodiment, the tension assembly includes a telescopic column 14, with two ends of the telescopic column 14 being movably connected to second tension springs 15. The two second tension springs 15 are respectively fixedly connected to the corresponding first rotating plate 5 and second rotating plate 6. A movable bracket 16 is sleeved on the outer side of the telescopic column 14, with both ends of the movable bracket 16 being fixedly connected to the first rotating plate 5 and the second rotating plate 6.

[0028] Specifically, through the tension coordination between the telescopic column 14, the second tension spring 15, and the movable bracket 16 between the first rotating upright plate 5 and the second rotating upright plate 6, the first rotating upright plate 5 and the second rotating upright plate 6 will be pushed to separate appropriately, ensuring that the first upper rotating round rod 7 and the second upper rotating round rod 8 always remain in a horizontal state, so as to enhance the shock absorption effect.

[0029] In this embodiment, the lower ends of the first lower rotating round rod 22 and the second lower rotating round rod 23 are rotatably connected to sliding sleeve blocks 24. The inner sides of the two sliding sleeve blocks 24 are slidably connected to guide rods 25. The guide rods 25 are fixedly connected to the outer shell 1 of the seismic brace. The ends of the two sliding sleeve blocks 24 that are far apart are fixedly connected to third tension springs 26 sleeved on the outside of the guide rods 25. The other ends of the two third tension springs 26 are fixedly connected to the outer shell 1 of the seismic brace.

[0030] Specifically, as the duct storage rack 2 moves up and down, it also drives the connecting seat 21 to move. At this time, through the rotational cooperation of the first lower rotating rod 22 and the second lower rotating rod 23, the sliding sleeve 24 at its lower end can be driven to slide on the guide rod 25, thereby stretching or compressing the third tension springs 26 on both sides, further alleviating the vibration of the duct storage rack 2. Finally, through the coordinated cooperation of the upper and lower anti-vibration components, bidirectional anti-vibration protection for the duct body is achieved.

[0031] In this embodiment, two cylinders 20 are fixedly installed on the lower inner side of the duct storage rack 2. The output ends of the two cylinders 20 are fixedly connected to a clamping plate 17. Slider 18 is fixedly connected to both sides of the clamping plate 17. Two slide grooves 19 corresponding to the slider 18 are opened on both sides of the inner wall of the duct storage rack 2. The slider 18 is slidably connected to the inner side of the slide groove 19.

[0032] Specifically, after inserting the duct body into the inside of the duct holder 2, the two cylinders 20 are activated simultaneously. At this time, the clamping plate 17 will rise and fall smoothly with the help of the sliding cooperation between the slider 18 and the slide groove 19, thereby completing the stable clamping of the duct. Then, the duct body is fixedly installed in the target position by the threaded blocks at the four corners of the upper end of the duct holder 2.

[0033] More specifically, the cylinder 20 in this solution is a commercially available device that can be purchased by those skilled in the art. No structural modifications have been made to this device, and those skilled in the art are familiar with its working principle and can apply it proficiently. Therefore, this paper will not elaborate further. Furthermore, this solution aims to protect the physical structure, not the circuitry or software control. The mention of the processing circuit is merely a supplementary explanation of the feasibility and authenticity of this utility model; this utility model does not seek protection for the algorithm and circuitry technology. It is worth emphasizing that although the electronic control program is not described in detail in this solution, those skilled in the art can be familiar with and apply it based on their professional knowledge.

[0034] In this embodiment, the upper end of the inner wall of the duct storage rack 2 and the upper end of the clamping plate 17 are both provided with anti-slip textures.

[0035] Specifically, the anti-slip textures on the upper inner wall of the duct storage rack 2 and the upper end of the clamping plate 17 can effectively increase the friction between the duct body and the duct storage rack 2 and the clamping plate 17, thus preventing the duct body from sliding inside the duct storage rack 2.

[0036] It should be noted that this utility model is a bidirectional anti-vibration support for air ducts. In use, the air duct body is first inserted into the inner side of the air duct holder 2. Then, two cylinders 20 are activated simultaneously. At this time, the clamping plate 17 will smoothly rise and fall with the sliding cooperation of the slider 18 and the sliding groove 19, thus completing the stable clamping of the air duct. Then, the air duct body is fixedly installed at the target position by the threaded blocks at the four corners of the upper end of the air duct holder 2. When encountering vibration, the air duct body will drive the air duct holder 2 to move due to inertia. The stability of the air duct holder 2 during movement can be improved by sliding the guide rails 3 on both sides within the guide grooves 4 on the inner wall of the anti-vibration support shell 1. When the air duct holder 2 moves, it will drive the first rotating upright plate 5 and the second rotating upright plate 6 to rotate. Through the rotational cooperation of the first upper rotating round rod 7 and the second upper rotating round rod 8, the lifting block 9 can be driven to move up and down, causing the pull rod 12 to slide within the buffer cylinder 10. The sliding of the pull rod 12 will cause the circular plate 11 to compress or stretch the first tension spring 13 to absorb vertical vibration energy. Through the tension cooperation between the telescopic column 14, the second tension spring 15 and the movable bracket 16 between the first rotating upright plate 5 and the second rotating upright plate 6, the first rotating upright plate 5 and the second rotating upright plate 6 will be pushed to separate appropriately, ensuring that the first upper rotating circular rod 7 and the second upper rotating circular rod 8 always remain horizontal to enhance the buffering effect. While the duct holding rack 2 moves up and down, it will also drive the connecting seat 21 to move. At this time, through the rotation cooperation of the first lower rotating circular rod 22 and the second lower rotating circular rod 23, the sliding sleeve 24 at its lower end can be driven to slide on the guide rod 25, thereby stretching or compressing the third tension spring 26 on both sides, further alleviating the vibration of the duct holding rack 2. Finally, through the coordinated cooperation of the upper and lower anti-vibration components, bidirectional anti-vibration protection for the duct body is achieved, which is quite practical.

[0037] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims. The scope of protection of this utility model is defined by the appended claims and their equivalents.
