Description

Technical Field

[0001] The utility model belongs to the technical field of ventilation ducts, and in particular relates to a ventilation duct with a suspension structure. Background Art

[0002] Ventilation ducts are short for ventilation ducts, which are metal or non-metallic pipes used in ventilation and air-conditioning engineering for industrial and civil buildings. Ventilation ducts are a kind of municipal infrastructure designed to circulate air and reduce the concentration of harmful gases.

[0003] The ventilation ducts with hanging structures currently available on the market have the following problems in actual use:

[0004] 1. In actual use, the traditional ventilation duct with a hanging structure needs to be installed and hung on a column, and the spacing of the hanging device of the traditional ventilation duct with a hanging structure is fixed. When the installed column is thick, the hanging device of the ventilation duct cannot be installed, and the compatibility is poor during use;

[0005] 2. During the use of most ventilation ducts with a hanging structure, one end of the ventilation duct will be installed in the outside world. At this time, some low-quality objects from the outside world may enter the ventilation channel, thereby affecting the ventilation effect of the ventilation duct. Most ventilation ducts themselves do not have devices to block objects, and their protection is poor when used. Utility Model Content

[0029] like Figure 1-5 As shown, a ventilation duct with a hanging structure of the utility model comprises a ventilation duct with a hanging structure, comprising a duct body 1, a fixing rod 3 is provided at the bottom of the duct body 1, a cavity 4 is opened inside the fixing rod 3, a telescopic rod 5 is installed inside the cavity 4, by installing the telescopic rod 5 inside the cavity 4, when the installed column is thicker, the telescopic rod 5 can be extended outward, thereby driving the movement of the side rod 7, so that the column can be accommodated between the side rods 7, and the compatibility of the ventilation duct with a hanging structure is improved during use, a baffle 6 is welded at one end of the telescopic rod 5, the baffle 6 is located inside the cavity 4, and the side rod 7 is welded at the other end of the telescopic rod 5, an externally threaded rod 8 is sleeved inside the side rod 7, a nut 9 is installed on the surface of the externally threaded rod 8, and the nut 9 is located on the side of the side rod 7, and the nut 9 can be installed on the externally threaded rod 8 by installing the nut 9, so that the ventilation duct is fixed to the column, which is very convenient to use.

[0030] A fixing frame 10 is provided at one end of the pipe body 1, a filter screen 11 is installed inside the fixing frame 10, a fixing plate 12 is welded to the side of the fixing frame 10, and the fixing plate 12 is connected to the pipe body 1 by bolts. By installing the filter screen 11, the filter screen 11 can be used to block and protect one end of the pipe located outside, so that external objects will not enter the interior of the pipe body 1, and the protection is strong when used.

[0031] A limit plate 2 is welded to the bottom of the pipe body 1, and the limit plates 2 are distributed in a symmetrical form. The sides of the fixing rods 3 are attached to the limit plates 2, and the fixing rods 3 are connected to the limit plates 2 by bolts. By installing the limit plates 2, the limit plates 2 are distributed in a symmetrical form at the same time. At this time, the fixing rods 3 can be limited between the limit plates 2 and fixed with bolts, which has strong stability during use.

[0032] A fixing block 15 is welded to the bottom of the pipe body 1, a sleeve 16 is welded to the bottom of the fixing block 15, a shaft rod 14 is sleeved inside the sleeve 16, a fixing frame 13 is welded on the surface of the shaft rod 14, and a fixing frame 10 is welded on the other end of the fixing frame 13. By sleeve-connecting the shaft rod 14 inside the sleeve 16, the shaft rod 14 can be used to provide a rotating effect for the fixing frame 10. When the filter screen 11 needs to be cleaned, the fixing frame 10 can be directly rotated by the shaft rod 14, thereby driving the filter screen 11, which is very convenient to use.

[0033] The fixing plates 12 are distributed in a symmetrical form, and a handle 17 is welded on the top of the fixing frame 10. By installing the handle 17, when the fixing frame 10 needs to be rotated, the handle 17 can be directly used to rotate the fixing frame 10, which is very convenient to use.

[0034] The side rods 7 are distributed in a symmetrical form, and the nuts 9 are distributed in a symmetrical form.

[0035] The working principle of the ventilation duct with a hanging structure: when using the ventilation duct with a hanging structure, a suitable installation position should be selected first, such as a column or a rod-shaped object as the installation basis. At this time, the telescopic rod 5 can be extended outward according to the thickness of the installed column, thereby driving the movement of the side rod 7 so that the column can be accommodated between the side rods 7. At this time, the external threaded rod 8 is passed through the side rod 7 and fixed with a nut 9, which improves the compatibility of the ventilation duct with a hanging structure during use. Then, the fixing frame 10 is rotated with the shaft rod 14 as the center through the handle 17. When it is rotated to a suitable position, the fixing frame 10 is rotated to a suitable position. After the filter screen 11 is in position, the fixing plate 12 is fixed to the side of the pipe body 1 by bolts, thereby achieving a fixing effect for the fixing frame 10. Since the filter screen 11 is installed inside the fixing frame 10, the filter screen 11 can be fixed at this time. The filter screen 11 can be used to block and protect one end of the external pipe, so that external objects will not enter the interior of the pipe body 1. The protective performance is strong when in use. When the filter screen 11 needs to be cleaned, the fixing frame 10 can be directly rotated by the shaft 14, thereby driving the filter screen 11. When the filter screen 11 moves out of one end of the pipe, the filter screen 11 is cleaned, which is very convenient to use.
