Description

Technical Field

[0001] The utility model relates to the technical field of air duct brackets, and more particularly to a compression device for an anti-seismic bracket of an air duct. Background Art

[0002] During the use of air ducts, if they are in an unstable state for a long time, it will accelerate the aging and wear of the air ducts. Therefore, when laying air ducts, brackets are usually installed around the air ducts. The use of brackets can effectively reduce the vibration of the air ducts, thereby extending the service life of the air ducts.

[0003] When some air ducts are heated, the molecular movement speed inside the ducts accelerates, causing the ducts to expand and increase in diameter. However, the position of the compression plate on the current duct bracket is usually fixed and cannot be adjusted, resulting in greater stress between the air duct and the compression plate, affecting the durability and service life of the air duct.

The support assembly 2 is an existing technology in the field of duct brackets and will not be described in detail here.

[0021] Furthermore, four connecting components 4 are evenly arranged, and the connecting components 4 include a first mounting frame 41 and a mounting plate 43. A second mounting frame 42 is arranged on the top of the first mounting frame 41. The bottom of the first mounting frame 41 is fixedly connected to the top of the clamping plate 3. A connecting rod 45 is arranged between the first mounting frame 41 and the second mounting frame 42. The mounting plate 43 is fixedly connected to the top of the wall by bolts.

[0022] Furthermore, the first mounting bracket 41 is fixedly connected to the first fixed shaft 411, and the second mounting bracket 42 is fixedly connected to the second fixed shaft 421. One end of the connecting rod 45 is rotatably connected to the surface of the first fixed shaft 411, and the other end of the connecting rod 45 is rotatably connected to the surface of the second fixed shaft 421. An extension block 431 is fixedly connected to the bottom of the mounting plate 43, and two extension blocks 431 are provided at the bottom of each mounting plate 43. The two extension blocks 431 are fixedly connected through a guide rod 44. The second mounting bracket 42 is sleeved on the surface of the guide rod 44, and the second mounting bracket 42 and the guide rod 44 form a sliding guide cooperation along the axial direction of the guide rod 44. A compression spring 441 is sleeved on the surface of the guide rod 44, and one end of the compression spring 441 is fixedly connected to one side of the second mounting bracket 42, and the other end of the compression spring 441 is fixedly connected to the extension block 431. The elastic force of the compression spring 441 can drive the pressing plate 3 to move downward.

[0023] The movable plate 55 is used to limit the receiving plate 31, thereby fixing the position of the pressing plate 3.

[0024] The working principle of the present invention is as follows: under normal conditions, the air duct passes through the top of the support frame 1, the support frame 1 supports the bottom of the air duct, the bottom of the moving plate 55 and the top of the receiving plate 31 conflict with each other, the moving plate 55 limits the clamping plate 3, fixes the position of the clamping plate 3, and the clamping plate 3 presses the top of the air duct into position.

[0025] When the air duct expands due to heat, its diameter becomes larger, the staff manually screws the rotating rod 54 to rotate it around its own axis. At the same time, the rotating rod 54 rotates, and the moving plate 55 is driven to move upward synchronously through the external thread 541 and the internal thread, and the moving plate 55 releases the resistance to the receiving plate 31 under the pressure of the air duct itself, and the clamping plate 3 and the receiving plate 31 move upward as a whole along the guide rod 52 and the rotating rod 54, and the clamping plate 3 moves and drives the second mounting bracket 42 to slide synchronously along the guide rod 44 through the first mounting bracket 41 and the connecting rod 45. The compression spring 441 contracts under the pressure of the second mounting bracket 42, and the elastic force of the compression spring 441 increases, and the compression spring 441 applies a downward force to the clamping plate 3, so that the clamping plate 3 continues to press the top of the air duct into position. After that, the staff reverses the rotating rod 54. Similarly, the moving plate 55 moves downward, and the bottom of the moving plate 55 conflicts with the top of the receiving plate 31, fixing the position of the clamping plate 3.
