Description

Technical Field

[0001] This utility model belongs to the field of ventilation duct technology, and specifically relates to a vibration damping and fixing bracket for ventilation ducts. Background Technology

[0002] Ventilation ducts are tubular structures made of galvanized steel sheets, stainless steel, and other materials, used to transport fluids such as air, smoke, and dust. They possess characteristics such as strong sealing, corrosion resistance, and pressure resistance, and come in various functional types including exhaust, air supply, and smoke extraction, as well as circular and rectangular shapes. They are primarily used for air conditioning and kitchen smoke extraction in residential and office buildings; ventilation and dust removal in factory workshops; fire smoke extraction and civil defense ventilation in subways and tunnels; ventilation and moisture control in warehouses and air circulation for grain storage; and exhaust and detoxification in laboratories, as well as airflow control in hospital clean rooms. They are a core infrastructure for achieving air circulation, temperature regulation, and pollutant removal in building and industrial environmental control.

[0003] For existing ventilation ducts, the vibration damping function is usually achieved by installing the damping structure separately inside the bracket, and then using multiple screws or screws in conjunction with other structures to fix the ventilation duct inside the bracket. It is not possible to install the vibration damping structure at the same time as quickly installing the ventilation duct. Utility Model Content

[0004] The purpose of this utility model is to provide a vibration damping and fixing bracket for ventilation ducts, which has the advantages of enabling rapid installation and vibration damping of ventilation ducts.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a vibration damping and fixing bracket for ventilation ducts, including a fixing frame, a sliding hole on one side of the fixing frame, a pull-out plate slidably connected inside the sliding hole, two sets of limiting rods slidably connected inside the pull-out plate and on three sides of the fixing frame, an arc-shaped plate welded to one end of each of the two sets of limiting rods, a telescopic spring connected to the pull-out plate and three sides of the surface of the fixing frame by spring fixing members, two sets of heat dissipation holes on three sides of the fixing frame and the surface of the pull-out plate, and a first connecting plate welded to both sides of the upper end of the fixing frame, with mounting holes at both ends of the surface of the first connecting plate.

[0006] The above technical solution is adopted as follows: After the ventilation duct is installed inside the fixed frame from the bottom, the pull-out plate is pushed from the position of the sliding hole into the fixed frame. When installing the ventilation duct and pushing the pull-out plate, the arc-shaped surface of the arc plate will contact the ventilation duct and be squeezed by the ventilation duct. At this time, the arc plate will move a distance inside the fixed frame and the pull-out plate respectively using the limiting rod, and squeeze the telescopic spring to a certain extent. The telescopic spring is used to absorb the vibration of the ventilation duct. In addition, the fixed frame can be installed at the lower end of the ceiling of the house using the mounting holes on the surface of the first connecting plate. The heat dissipation holes are used to dissipate heat when transporting high-temperature gas, thus achieving the effect of facilitating the vibration absorption of the ventilation duct.

[0007] The present invention is further configured such that rotating rods are welded to both sides of the surface of the pull-out plate, and rotating plates are rotatably connected to the surface of the rotating rods.

[0008] Using the above technical solution, the rotating plate can rotate on the surface of the rotating rod.

[0009] The present invention is further configured such that a mounting plate is welded to one end of the rotating rod, and a torsion spring is sleeved on the surface of the rotating rod, and the two ends of the torsion spring are respectively connected between the mounting plate and the rotating plate through spring fixing members.

[0010] The above technical solution is adopted: a torsion spring is used to drive the rotating plate to rotate on the surface of the rotating rod.

[0011] The present invention is further configured such that a hanging plate is welded to one end of the rotating plate, and a fixing column is welded to both ends of one side of the fixing frame.

[0012] Using the above technical solution: the rotation of the rotating plate will cause the hanging plate to hang on the surface of the fixed column.

[0013] The present invention is further configured such that two sets of fixing plates are welded to the surface of the fixing column, the hanging plate is detachably connected to the fixing column, and the hanging plate can be set between the two sets of fixing plates.

[0014] The above technical solution is adopted: the fixing plate is used to block both sides of the hanging plate to prevent the pull-out plate from moving out of the fixing frame.

[0015] The present invention is further configured such that a spring pull rod is bolted to one side of the fixed plate, a second connecting plate is bolted to the piston end of the spring pull rod, and three sets of limiting posts are welded to one side of the second connecting plate, and the limiting posts are detachably connected to the inside of one set of fixed plates.

[0016] Using the above technical solution: after the hanging plate is hung on the surface of the fixed column, the spring rod will pull the second connecting plate and the limiting column to move, so that the limiting column is positioned inside the fixed plate. This can limit the hanging plate and prevent the hanging plate from detaching from the surface of the fixed column.

[0017] In summary, this utility model has the following beneficial effects:

[0018] 1. After the ventilation duct is installed inside the fixed frame from the bottom, the pull-out plate is pushed from the sliding hole into the fixed frame. When installing the ventilation duct and pushing the pull-out plate, the curved surface of the curved plate will contact the ventilation duct and be squeezed by the ventilation duct. At this time, the curved plate will move a distance inside the fixed frame and the pull-out plate using the limit rod, and squeeze the telescopic spring to a certain extent. The telescopic spring is used to dampen the ventilation duct. The fixed frame can be installed at the bottom of the ceiling of the house using the mounting holes on the surface of the first connecting plate. The heat dissipation holes are used to dissipate heat when transporting high-temperature gas, thus achieving the effect of facilitating the damping of the ventilation duct.

[0019] 2. When the pull-out plate is installed, the torsion spring will drive the rotating plate to rotate on the rotating rod surface, so that the hanging plate at one end of the rotating plate is hung on the surface of the fixed column. The fixed plate is used to block the two sides of the hanging plate to prevent the pull-out plate from moving out of the fixed frame. After the hanging plate is hung on the surface of the fixed column, the spring rod will pull the second connecting plate and the limiting post to move, so that the limiting post is positioned inside the fixed plate. This can limit the hanging plate and prevent the hanging plate from detaching from the surface of the fixed column, thus achieving the effect of quick installation of ventilation ducts and brackets.

A pull plate 404 is slidably connected inside the sliding hole 405. Two sets of limiting rods 403 are slidably connected inside the pull plate 404 and on three sides of the fixing frame 1. An arc-shaped plate 401 is welded to one end of each of the two sets of limiting rods 403. A telescopic spring 402 is connected to the surface of the pull plate 404 and the surface of the fixing frame 1 on three sides by spring fixing members. Two sets of heat dissipation holes 5 are provided on three sides of the fixing frame 1 and the surface of the pull plate 404. A first connecting plate 2 is welded to both sides of the upper end of the fixing frame 1. Mounting holes 3 are provided at both ends of the surface of the first connecting plate 2.

[0027] Brief description of the usage process: After the ventilation duct is installed inside the fixed frame 1 from the bottom, the pull plate 404 is pushed from the position of the sliding hole 405 into the fixed frame 1. When installing the ventilation duct and pushing the pull plate 404, the arc surface of the arc plate 401 will contact the ventilation duct and be squeezed by the ventilation duct. At this time, the arc plate 401 will move a distance inside the fixed frame 1 and the pull plate 404 respectively using the limiting rod 403, and squeeze the telescopic spring 402 to a certain extent. The telescopic spring 402 is used to dampen the ventilation duct. The fixed frame 1 can be installed at the lower end of the ceiling of the house using the mounting hole 3 on the surface of the first connecting plate 2. The heat dissipation hole 5 is used to dissipate heat when conveying high temperature gas, thus achieving the effect of facilitating the damping of the ventilation duct.

[0028] Example 2:

[0029] refer to Figure 1-3 Both sides of the pull-out plate 404 are welded with rotating rods 608, and rotating plates 607 are rotatably connected to the surface of the rotating rods 608.

[0030] Furthermore, a mounting plate 610 is welded to one end of the rotating rod 608, and a torsion spring 609 is sleeved on the surface of the rotating rod 608. The two ends of the torsion spring 609 are respectively connected between the mounting plate 610 and the rotating plate 607 through spring fixing members.

[0031] Furthermore, a hanging plate 606 is welded to one end of the rotating plate 607, and a fixing column 605 is welded to both ends of one side of the fixing frame 1.

[0032] Furthermore, two sets of fixing plates 604 are welded to the surface of the fixing column 605, and the hanging plate 606 is detachably connected to the fixing column 605, and the hanging plate 606 can be set between the two sets of fixing plates 604.

[0033] Furthermore, a spring rod 602 is bolted to one side of the fixed plate 604, and a second connecting plate 601 is bolted to the piston end of the spring rod 602. Three sets of limiting posts 603 are welded to one side of the second connecting plate 601, and the limiting posts 603 are detachably connected to the inside of one set of fixed plates 604.

[0034] Brief description of the usage process: When the pull-out plate 404 is installed, the torsion spring 609 will drive the rotating plate 607 to rotate on the surface of the rotating rod 608, so that the hanging plate 606 at one end of the rotating plate 607 is hung on the surface of the fixed post 605. The fixed plate 604 is used to block the two sides of the hanging plate 606 to prevent the pull-out plate 404 from moving out of the fixed frame 1. After the hanging plate 606 is hung on the surface of the fixed post 605, the spring rod 602 will pull the second connecting plate 601 and the limiting post 603 to move, so that the limiting post 603 is positioned inside the fixed plate 604. This can limit the hanging plate 606 and prevent the hanging plate 606 from detaching from the surface of the fixed post 605, thus achieving the effect of quick installation of ventilation ducts and brackets.
