Description

Technical Field

[0001] The utility model relates to the technical field of fiber fabric air ducts, in particular to an internally supported fiber fabric air duct. Background Art

[0002] In the 1960s and 1970s, the global frozen food industry began experimenting with fabricating air vents shaped like cloth bags from ordinary cotton fabric to meet the specialized requirements of high cooling capacity and low air speeds in refrigerated areas. Similarly, in China in the 1950s and 1960s, numerous cases of installing cloth bag ducts, often referred to as "bag ducts," occurred in the refrigeration and freezing industries. Over the past 20 years, with continuous innovations in fiber materials and textile technology worldwide, an increasing number of fibers with specialized properties have been incorporated into air distribution systems. This has continuously expanded the application of fabric air distribution systems, making them a popular ventilation system that now commands a significant market share.

[0003] In places with high aesthetic requirements, such as gymnasiums, offices, and commercial buildings, internally supported fiber fabric air ducts are generally used to keep the air ducts rounded in shape. However, although existing internally supported fiber fabric air ducts can be disassembled and supported, their supporting effect is average, and it is also inconvenient to adjust the height and horizontal position of the air ducts.

[0004] To this end, an internally supported fiber fabric air duct is proposed. Summary of the Invention

[0013] Furthermore, the air duct sections are connected by zippers, which facilitates the disassembly of the air ducts and is simple and effective.

[0014] Furthermore, the telescopic adjustment structure includes a sleeve and an insertion rod, one end of the insertion rod is elastically plugged into the inside of the sleeve, and the other end is fixed to the air duct section.

[0015] Furthermore, a spring is provided at the top end of the sleeve, and the spring is connected to the top end of the insertion rod.

[0016] Furthermore, the sleeve is provided with a threaded through-hole corresponding to the threaded adjustment rod, and the threaded adjustment rod is in close contact with the insertion rod after passing through the threaded through-hole.

[0017] Furthermore, a T-shaped slider is provided at the top of the sleeve, and the ceiling is provided with a T-shaped slot that slides with the T-shaped slider, so that the sleeve can be slid using the T-shaped slider, thereby facilitating adjustment of the horizontal position of the air duct.

[0018] Furthermore, mounting plates with mounting holes are respectively provided on both sides of the suspended ceiling.

[0019] Compared with the prior art, the beneficial effects of the present invention are:

[0020] A groove is provided on the inner wall of the air duct for engaging with the support ring, which can maintain the stability of the support ring and achieve better support effect and durability;

[0026] The technical solutions in the embodiments of the present invention will be described clearly and completely below with reference to the accompanying drawings in the embodiments of the present invention.

[0027] Example 1:

[0028] See also Figure 1-3 , the utility model provides a technical solution:

[0029] An internally supported fiber fabric air duct comprises an air duct section 6 and a suspended ceiling 1. The air duct sections 6 are detachably connected to each other, which facilitates the disassembly of the air duct section 6 and is also conducive to assembly. At the same time, in order to better support the air duct and keep it in a rounded shape for a long time to facilitate ventilation, an internal support ring 61 is installed inside the air duct section 6 to be embedded therewith. In order to achieve the up and down height adjustment of the air duct, a telescopic adjustment structure is installed at the bottom end of the suspended ceiling 1 so that the bottom end of the telescopic adjustment structure is fixed to the air duct section 6 and the height can be adjusted up and down. In order to fix the height of the thickness, the telescopic adjustment structure is adjusted and fixed by a threaded adjustment rod 5. In order to facilitate the overall installation of the device, mounting plates 2 with mounting holes are respectively provided on both sides of the suspended ceiling 1, which are convenient for fixing to the wall with bolts or the like.

[0030] like Figure 3 As shown:

[0031] An annular recess 62 is provided inside the air duct section 6 so that the inner support ring 61 fits in the annular recess 62 , thereby supporting the air duct and preventing the inner support ring 61 from falling off, thereby facilitating stable use.

[0032] like Figure 1 As shown:

[0033] The air duct sections 6 are connected by zippers 7, so that the air duct can be quickly disassembled or assembled, which is convenient for use.

[0034] like Figure 2 As shown:

[0035] The telescopic adjustment structure includes a sleeve 3 and an insertion rod 4. One end of the insertion rod 4 is elastically plugged into the inside of the sleeve 3, and the other end is fixed to the air duct section 6. In order to achieve elastic plugging, a spring 9 is installed at the top end of the sleeve 3, and the spring 9 is connected to the top end of the insertion rod 4, so that a threaded through-hole corresponding to the threaded adjustment rod 5 is installed on the insertion rod 4 inside the sleeve 3, so that the threaded adjustment rod 5 is in close contact with the insertion rod 4 after passing through the threaded through-hole, and the friction force is used to limit the adjusted position of the insertion rod 4 to fix the overall height.

[0036] Example 2:

[0037] The difference from Example 1 is that a T-shaped slider 8 is installed at the top of the sleeve 3. In order to achieve horizontal sliding adjustment, a T-shaped slot that slides with the T-shaped slider 8 is opened on the ceiling 1. At this time, the T-shaped slider 8 can be used to slide to adjust the front and rear position of the air duct, which is convenient to use.

[0038] How it works:

[0039] When the height needs to be adjusted, the threaded adjustment rod 5 is turned to release the restriction on the insertion rod 4. At this time, the insertion rod 4 can move up and down along the sleeve 3 to adjust the position of the air duct, which is convenient for use. Then the threaded adjustment rod 5 is screwed back into the sleeve 3 so that one end of the threaded adjustment rod 5 is in close contact with the insertion rod 4 by friction, thereby limiting the height position of the air duct.

[0040] When the front and rear position of the air duct needs to be adjusted, the air duct is pushed and the T-shaped slider 8 is used to slide horizontally along the T-shaped slot, which is simple and effective.

[0041] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
