A galvanized steel sheet duct and supporting hanger structure

Abstract

This utility model discloses a structure for a galvanized steel sheet duct and its supporting hanger. It includes a hanger installed at the bottom of the duct, an anti-sway frame fitted over the surface of the duct, and four arc-shaped plates (first type) fixedly connected to the bottom of the hanger. Arc-shaped plates (second type) are rotatably connected to the surface of each arc-shaped plate (first type) via a pivot. A hook is bolted to the left side of each arc-shaped plate (first type), and a fixing block is fixedly connected to the left side of each arc-shaped plate (second type). A handle is rotatably connected to the surface of the fixing block via a pivot, and a connecting rod is rotatably connected to the inner wall of the handle. This utility model, by rotating the threaded rod, moves its surface into the inner wall of the threaded block, thereby strengthening the integration between the hanger and the anti-sway frame. This effectively reduces the impact force generated during duct use, preventing the hanger from swaying and improving the stability of the galvanized steel sheet duct.

Description

Technical Field

[0001] This utility model belongs to the field of air duct technology, and in particular relates to a galvanized steel sheet air duct and supporting hanger structure. Background Technology

[0002] Galvanized steel sheet ducts are the core components for air transport in ventilation and air conditioning projects. Due to the corrosion resistance of the galvanized layer and the structural strength of the steel sheet, they are widely used in civil buildings and industrial plants. Support rods are the key structures for installing galvanized steel sheet ducts. It is necessary to design reasonable specifications and installation methods according to the weight, size and installation environment of the duct to ensure long-term stable installation of the duct.

[0003] Some galvanized steel sheet ducts are supported by hangers. During the use of galvanized steel sheet ducts, the impact force generated by the internal airflow may cause the hangers to sway. Therefore, a structure is needed for the galvanized steel sheet duct and supporting hangers. By connecting the hangers and anti-sway frames with threaded rods, the hangers and anti-sway frames can be fixed together as one unit. This allows the anti-sway frames to restrain the supporting hangers, effectively reducing the impact force generated during the use of the duct and thus improving the stability of the galvanized steel sheet duct. Utility Model Content

[0004] The purpose of this utility model is to provide a galvanized steel sheet duct and supporting hanger structure, which connects the hanger and the anti-sway frame through a threaded rod, fixing the hanger and the anti-sway frame as a whole. This allows the anti-sway frame to constrain the supporting hanger, effectively reducing the impact force generated during the use of the duct and thus improving the stability of the galvanized steel sheet duct, thereby solving the aforementioned technical problems.

[0005] The technical solution of this utility model to solve the above-mentioned technical problems is as follows: A galvanized steel sheet air duct and supporting hanger structure includes a hanger installed at the bottom of the air duct, an anti-sway frame sleeved on the surface of the air duct, four arc-shaped plates (first type) fixedly connected to the bottom of the hanger, arc-shaped plates (second type) rotatably connected to the surface of the arc-shaped plates (first type) via a rotating shaft, a hook fixedly connected to the left side of the arc-shaped plates (first type) by bolts, a fixing block fixedly connected to the left side of the arc-shaped plates (second type), a handle rotatably connected to the surface of the fixing block via a rotating shaft, a connecting rod rotatably connected to the inner wall of the handle, a U-shaped bolt rod slidably connected to the inner wall of the connecting rod, four nut blocks threadedly connected to the surface of the U-shaped bolt rod, an internally threaded pipe installed between the two arc-shaped plates (first type) and the arc-shaped plates (second type), a threaded rod threadedly connected to the inner wall of the internally threaded pipe, and an internally threaded block fixedly connected to the bottom of the anti-sway frame by bolts.

[0006] Preferably, rubber gaskets are attached to the inner walls of both the first and second arc-shaped plates, and the rubber gaskets are arc-shaped rubber gaskets.

[0007] Preferably, the inner wall of the hook is engaged with the surface of the U-shaped bolt rod.

[0008] Preferably, the surface of the threaded rod is adapted to the inner wall of the internal threaded block, and the surface of the threaded rod is threadedly connected to the inner wall of the internal threaded block.

[0009] Preferably, a connecting block is fixedly connected to the left side of the internal threaded block, and a bolt rod is threadedly connected to the inner wall of the connecting block, with the end of the bolt rod extending into the inner cavity of the internal threaded block.

[0010] The beneficial effects of this utility model are: 1. This utility model, by rotating the threaded rod, moves the surface of the threaded rod into the inner wall of the internal thread block, thereby strengthening the integrity between the hanger and the anti-sway frame. This effectively reduces the impact force generated during the use of the duct, thus improving the stability of the galvanized steel duct. 2. By setting rubber gaskets, the inner walls of the first and second arc-shaped plates are protected, reducing the possibility of damage to the internally threaded pipe when the first and second arc-shaped plates come into direct contact with it. 3. This utility model enhances the connection stability between the threaded rod and the internal threaded block by using the connecting block and the bolt rod together, and reduces the occurrence of displacement between the threaded rod and the internal threaded block due to vibration.

Detailed Implementation

[0013] In the following description, embodiments of the galvanized steel sheet duct and support rod structure of the present invention will be described with reference to the accompanying drawings.

[0014] Example 1: Figures 1-6 This invention illustrates an embodiment of a galvanized steel sheet duct and supporting hanger structure, comprising: a hanger 2 installed at the bottom of the duct 1; an anti-sway frame 3 fitted onto the surface of the duct 1; four arc-shaped plates 4 fixedly connected to the bottom of the hanger 2; arc-shaped plates 5 rotatably connected to the surface of the arc-shaped plates 4 via a pivot; rubber gaskets 6, which are arc-shaped, are attached to the inner walls of both the arc-shaped plates 4 and 5. The rubber gaskets 6 protect the inner walls of the arc-shaped plates 4 and 5, reducing the risk of damage to the internally threaded pipe 13 when they come into direct contact. The left side of the arc-shaped plates 4 is fixedly connected by bolts. A hook 7 is attached. A fixing block 8 is fixedly connected to the left side of the arc plate 2 5. A handle 9 is rotatably connected to the surface of the fixing block 8 via a rotating shaft. A connecting rod 10 is rotatably connected to the inner wall of the handle 9. A U-bolt rod 11 is slidably connected to the inner wall of the connecting rod 10. Four nut blocks 12 are threadedly connected to the surface of the U-bolt rod 11. An internally threaded pipe 13 is installed between the two arc plates 1 4 and the arc plate 2 5. A threaded rod 14 is threadedly connected to the inner wall of the internally threaded pipe 13. An internally threaded block 15 is fixedly connected to the bottom of the anti-sway frame 3 by bolts. The surface of the threaded rod 14 is adapted to the inner wall of the internally threaded block 15. The surface of the threaded rod 14 is threadedly connected to the inner wall of the internally threaded block 15.

[0015] Example 2: Figures 1-6This invention illustrates an embodiment of a galvanized steel sheet duct and supporting hanger structure, comprising: a hanger 2 installed at the bottom of the duct 1; an anti-sway frame 3 fitted onto the surface of the duct 1; four arc-shaped plates 4 fixedly connected to the bottom of the hanger 2; arc-shaped plates 5 rotatably connected to the surface of the arc-shaped plates 4 via a pivot; hooks 7 fixedly connected to the left side of the arc-shaped plates 4 via bolts; a fixing block 8 fixedly connected to the left side of the arc-shaped plates 5; a handle 9 rotatably connected to the surface of the fixing block 8 via a pivot; a connecting rod 10 rotatably connected to the inner wall of the handle 9; a U-shaped bolt rod 11 slidably connected to the inner wall of the connecting rod 10; and the inner wall of the hooks 7 engaging with the surface of the U-shaped bolt rod 11. Four nut blocks 12 are threadedly connected to the surface of rod 11. An internally threaded tube 13 is installed between the two arc-shaped plates 1 and 2. A threaded rod 14 is threadedly connected to the inner wall of the internally threaded tube 13. An internally threaded block 15 is fixedly connected to the bottom of the anti-sway frame 3 by bolts. A connecting block 16 is fixedly connected to the left side of the internally threaded block 15. A bolt rod 17 is threadedly connected to the inner wall of the connecting block 16. The end of the bolt rod 17 extends into the inner cavity of the internally threaded block 15. The connection between the threaded rod 14 and the internally threaded block 15 is strengthened by the cooperation of the connecting block 16 and the bolt rod 17, and the displacement between the threaded rod 14 and the internally threaded block 15 caused by vibration is reduced.

[0016] Working principle: When using this utility model, the user moves the internally threaded tube 13 so that its surface contacts the inner wall of the arc-shaped plate 4. Then, the arc-shaped plate 5 is moved so that the surface of the U-shaped bolt rod 11 contacts the hook 7. At this time, the user presses the handle 9. During this process, the handle 9 is limited by the fixing block 8, causing the handle 9 to move the connecting rod 10. This allows the connecting rod 10 to engage the U-shaped bolt rod 11 with the hook 7. The nut block 12 can be used to secure the U-shaped bolt rod. The position of 11 is adjusted so that the arc plate 4 and the arc plate 5 can fix the internal threaded pipe 13. Then, the threaded rod 14 is rotated so that the surface of the threaded rod 14 moves to the inner wall of the internal threaded block 15, so that the threaded rod 14 and the internal threaded block 15 are threadedly connected, thereby fixing the hanger 2 and the anti-sway frame 3 into one unit. Then, the anti-sway frame 3 restrains the swaying of the hanger 2, effectively reducing the impact force generated during the use of the air duct and causing the hanger to sway, thereby improving the stability of the galvanized steel plate air duct.

[0017] In summary, the structure of this galvanized steel duct and supporting rod, by rotating the threaded rod 14, allows the surface of the threaded rod 14 to move into the inner wall of the internal thread block 15, thereby strengthening the integration between the rod 2 and the anti-sway frame 3. This effectively reduces the impact force generated during the use of the duct, thus improving the stability of the galvanized steel duct.
