Description

Technical Field

[0001] This utility model relates to the field of damping mesh technology, and in particular to a tensioning structure for damping mesh. Background Technology

[0002] A damping net is a mesh structure installed inside a wind tunnel duct. It is mainly used to reduce airflow turbulence and homogenize velocity distribution. It breaks down large-scale eddies into smaller-scale turbulence through physical barriers, thereby improving the stability of the airflow in the test section. The tensioning structure is a mechanical device used to fix and adjust the tension of the damping net. Its core function is to ensure that the damping net remains flat and without slack under the impact of high-speed airflow, preventing vibration or deformation from affecting the uniformity of airflow.

[0003] However, the existing connection between the tensioning structure and the damping net is made by bolts. Since there are many connection points between the tensioning structure and the damping net, the disassembly and assembly of the damping net is time-consuming and labor-intensive. Therefore, we propose a tensioning structure for the damping net. Utility Model Content

[0004] The purpose of this invention is to provide a tensioning structure for damping nets that can solve the problem of time-consuming and labor-intensive connection between some existing tensioning structures and damping nets.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a tensioning structure for a damping mesh, comprising:

[0006] cylindrical body;

A second spring is sleeved on the positioning rod, and one end of the second spring is fixedly connected to the front outer surface of the hook, while the other end of the second spring is fixedly connected to the handle.

[0009] Preferably, the first tensioning mechanism includes a movable plate, a threaded section, a threaded sleeve, and a first spring. The movable plate is movably sleeved on the movable rod, and a threaded section is provided at the other end of the movable rod. A threaded sleeve is threadedly installed on the threaded section, and the threaded sleeve abuts against the top of the movable plate. The first spring is sleeved on the movable rod, and both ends of the first spring are fixedly connected to the top of the base plate and the bottom of the movable plate, respectively.

[0010] Preferably, the top, bottom, and front and rear outer surfaces of the cylinder are each provided with at least two sets of second tensioning mechanisms equal to the first tensioning mechanism.

The operation is simple and solves the problem that the connection between the existing tensioning structure and the damping net is connected by bolts. Since there are many connection points between the tensioning structure and the damping net, the disassembly and assembly of the damping net is time-consuming and labor-intensive. This improves the practicality of the structure.

The first tensioning mechanism 2 is disposed on the cylinder 1 and includes a bottom plate 21, a movable rod 22 and a hook net mechanism 27. The bottom plate 21 is fixedly installed on the top of the cylinder 1. The movable rod 22 is movably passed through the bottom plate 21 and the top of the cylinder 1. The hook net mechanism 27 is disposed inside the cylinder 1 at one end of the movable rod 22. The hook net mechanism 27 includes a connecting block 271, a hook 272 and a locking plate 273. The connecting block 271 is fixedly installed on one end of the movable rod 22. The hook 272 is fixedly installed on the bottom of the connecting block 271. The locking plate 273 is hingedly installed on the hook 272. A set of operating openings is provided on the top, bottom and front and rear sides of the cylinder 1. A set of door panels 6 is hingedly installed at each of the four sets of operating openings. A set of observation windows 7 is provided on each of the four sets of door panels 6.

The positioning rod 274 is movably passed through the front side of the hook 272. One end of the positioning rod 274 is inserted into the positioning groove, and the other end of the positioning rod 274 is fixedly installed with the handle 275. The second spring 276 is sleeved on the positioning rod 274. One end of the second spring 276 is fixedly connected to the outer surface of the front side of the hook 272, and the other end of the second spring 276 is fixedly connected to the handle 275. Through the first tensioning mechanism 2, the damping net 4 can be hooked or detached for disassembly and assembly simply by pulling the handle 275 along with the positioning rod 274 onto the locking plate 273 to rotate the locking plate 273 and open or close the hook 272. This is simple to operate and solves the problem that the connection between the existing tensioning structure and the damping net is connected by bolts, which leads to time-consuming and labor-intensive disassembly and assembly of the damping net due to the large number of connection points between the tensioning structure and the damping net. This improves the practicality of the structure.

[0026] The first tensioning mechanism 2 includes a movable plate 23, a threaded section 24, a threaded sleeve 25, and a first spring 26. The movable plate 23 is movably sleeved on the movable rod 22. A threaded section 24 is provided at the other end of the movable rod 22, and a threaded sleeve 25 is threadedly installed on the threaded section 24. The threaded sleeve 25 abuts against the top of the movable plate 23. The first spring 26 is sleeved on the movable rod 22, and both ends of the first spring 26 are fixedly connected to the top of the bottom plate 21 and the bottom of the movable plate 23, respectively.

Each of the second tensioning mechanisms 3 is also equipped with a set of dampers 5 in the same way. Through the dampers 5, the damping net 4 can be buffered by the vibration caused by airflow during use, reducing the wear of the damping net 4. At the same time, under the action of the door panel 6, it is convenient for the user to operate the first tensioning mechanism 2 and the second tensioning mechanism 3, ensuring the use effect of the structure and facilitating the promotion and use of the structure.

[0027] Working principle: When adjusting the first tensioning mechanism 2, the threaded sleeve 25 can be rotated up or down to compress the first spring 26 or release the first spring 26, thereby changing the tension of the damping net 4 by the movable rod 22 through the hook net mechanism 27, thus adjusting the tension of the damping net 4. The second tensioning mechanism 3 works similarly. When disassembling the damping net 4, the door panel 6 is opened, and the handle 275 is pulled to disengage the positioning rod 274 from the positioning groove on the lock plate 273. Then, the lock plate 273 is rotated to open the hook 272, thereby detaching the damping net 4 from the hook 272. The second tensioning mechanism 3 works similarly to achieve the disassembly of the damping net 4.
