[0002] Ventilation ducts, also known as ventilation ducts, are metal or non-metallic pipes used in ventilation and air-conditioning projects in industrial and civil buildings. They are mainly used to circulate air and reduce the concentration of harmful gases. Ventilation ducts can be divided into many types according to their materials, such as stainless steel ventilation ducts, carbon steel ducts, galvanized sheet ducts, fiberglass ducts, etc. These ventilation ducts of different materials are suitable for different usage scenarios and need to be selected according to specific needs. According to the scope of application of ventilation ducts, they can be divided into ducts for central air-conditioning systems, ducts for purification air-conditioning systems, ducts for industrial ventilation systems, and ducts for environmental control systems. During the installation process, ventilation ducts usually require hangers to lift them.

Specific embodiments

[0024] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0025] Please refer to Figures 1-4 , an installation hanger for a ventilation duct, including two support components symmetrically arranged on both sides for fixing to the wall to support the hoisting, and further including two clamping components symmetrically arranged up and down between the two support components for clamping the duct up and down and capable of flipping and switching the clamping surface. Two switching components symmetrically arranged on both sides of the clamping component are used for supporting sliding clamping and pulling out to release the limit and rotating to switch the clamping surface.

[0026] In this embodiment: The support component includes a fixed plate 101. A support plate 103 is arranged below the fixed plate 101. Two screws 102 are symmetrically arranged before and after between the support plate 103 and the fixed plate 101. A clamping sleeve 104 is arranged on the screw 102. The screw 102 is welded to the support plate 103. The device is fixed to the wall through the fixed plate 101, and the duct is placed on the lower clamping component under the support of the support plate 103. Then, the clamping sleeve 104 is rotated to push the upper switching component to drive the clamping component to move downward to clamp and fix the duct;

[0027] In this embodiment: The clamping assembly includes a clamping plate 201. On the front and rear sides of the bottom of the clamping plate 201, two arc-shaped rib plates 202 are symmetrically arranged. On both sides of the upper surface of the clamping plate 201, two limiting plates 203 are symmetrically arranged. Below the limiting plates 203, sliders 204 are arranged. Below the sliders 204, a clamping plate 205 is arranged. At the central position of the clamping plate 205, a clamping bolt 206 is arranged. At the top of the clamping bolt 206, a clamping nut 207 is arranged. The limiting plates 203 are L-shaped. The limiting plates 203 are slidably connected to the clamping plate 201 through the sliders 204. When hoisting a square pipe, place the square pipe on the lower clamping plate 201. Then rotate the clamping sleeve 104 to push the two upper switching components to drive the upper clamping plate 201 to move downward along the screw rod 102 to clamp the square pipe. Then make the limiting plates 203 closely adhere to both sides of the square pipe under the restriction of the sliders 204, and tighten the clamping nut 207 so that it pulls the clamping plate 205 through the clamping bolt 206 to cooperate with the limiting plates 203 to clamp the clamping plate 201, thereby fixing the position of the limiting plates 203 and completely fixing the square pipe. When hoisting a circular pipe, first flip the clamping plate 201. Then place the circular pipe on the two arc-shaped rib plates 202 below, and repeat the above steps to make the upper clamping plate 201 move downward, so that the two upper arc-shaped rib plates 202 cooperate with the two lower arc-shaped rib plates 202 to clamp the circular pipe;

[0028] In this embodiment: The switching component includes a sliding plate 301. On one side inside the sliding plate 301, a clamping block 302 is arranged. On the side of the clamping block 302 close to the sliding plate 301, a rotating shaft 303 is arranged. At the end of the rotating shaft 303 away from the clamping block 302, a anti-disengagement plate 304 is arranged. A fixing nut 305 is installed on the rotating shaft 303. The clamping block 302 is square in shape. The clamping block 302 is welded to the clamping plate 201. The fixing nut 305 is threadedly connected to the rotating shaft 303. When hoisting a circular pipe, first loosen the fixing nut 305 to make the fixing nut 305 closely adhere to the anti-disengagement plate 304. Then move the sliding plate 301 along the rotating shaft 303 towards the anti-disengagement plate 304 to make the clamping block 302 disengage from the sliding plate 301. At this time, the sliding plate 301 will no longer restrict the rotating shaft 303, so that the clamping plate 201 can rotate around the rotating shaft 303. Then make the clamping plate 201 rotate 180 degrees around the rotating shaft 303. Finally, repeat the above opposite steps to make the clamping block 302 re-engage with the sliding plate 301, and tighten the fixing nut 305 to complete the switching.

[0029] Working principle: Fix this device to the wall surface through the fixing plate 101. When hoisting a square pipe, place the square pipe on the lower clamping plate 201, and then rotate the clamping sleeve 104 to push the two upper sliding plates 301 to drive the upper clamping plate 201 to move downward along the screw rod 102 through the clamping block 302. Under the support of the support plate 103, clamp the square pipe. Then, make the limiting plate 203 closely adhere to both sides of the square pipe under the restriction of the slider 204, and tighten the clamping nut 207 to pull the clamping plate 205 through the clamping bolt 206 to cooperate with the limiting plate 203 to clamp the clamping plate 201, thereby fixing the position of the limiting plate 203 and completely fixing the square pipe. When hoisting a circular pipe, first loosen the fixing nut 305 to make the fixing nut 305 closely adhere to the anti - detachment plate 304. Then, make the sliding plate 301 move along the rotating shaft 303 towards the anti - detachment plate 304 to make the clamping block 302 disengage from the sliding plate 301. At this time, the sliding plate 301 will no longer restrict the rotating shaft 303, enabling the clamping plate 201 to rotate around the rotating shaft 303. Then, make the clamping plate 201 flip 180 degrees around the rotating shaft 303. Finally, repeat the above - mentioned opposite steps to make the clamping block 302 re - engage with the sliding plate 301 and tighten the fixing nut 305 to complete the switching. After the switching is completed, place the circular pipe on the two lower arc - shaped ribs 202 and repeat the above steps to make the upper clamping plate 201 move downward, so that the two upper arc - shaped ribs 202 cooperate with the two lower arc - shaped ribs 202 to clamp the circular pipe.
