Embodiment Construction

[0016] Embodiment of the present invention is described below in conjunction with accompanying drawing, embodiment does not constitute limitation of the present invention:

[0017] Such as figure 1 , figure 2 As shown, the structure of this kind of negative pressure air duct includes a cylinder body 1 made of existing textile cloth, and the outer surface of the cylinder body 1 is screw-fixed with a bracket 2 along the axial direction. When in use, the bracket can support the side wall of the cylinder, provide support for the negative pressure behind, and prevent the problems of bending and suction.

[0018] In the above embodiment, specifically, the inner surface of the cylinder body 1 is provided with reinforcing brackets 3 crossed, and the outer ends of the reinforcement brackets 3 are perpendicular to the tangent line where the inner surface of the cylinder body 1 is located. The reinforcing bracket 3 is provided with a reinforcing ring 4 . When in use, the reinforcing ...

Abstract

The invention relates to a negative pressure wind pipe. Through the adoption of the wind pipe, the problem that under the negative pressure state, bending and shrinking are easy to occur can be effectively solved. The negative pressure wind pipe structurally comprises a cylinder body made of a textile fabric, wherein a bracket is spirally and fixedly arranged on the outer surface of the cylinder body in the axial direction; reinforcing brackets are arranged on the inner surface of the cylinder body in a crossed manner, and stiffening rings are arranged on the reinforcing brackets. The negative pressure weaving wind pipe disclosed by the invention is simple to operate, convenient to use, and suitable for varied places.

Description

technical field [0001] The invention relates to a negative pressure air duct. Background technique [0002] The textile air duct is a cylindrical air duct made of cloth, which is mainly used for ventilation. However, because the fabric has no supporting function, the textile air duct is always prone to bending and deflated under negative pressure, which seriously affects the use of the air duct. Contents of the invention [0003] The technical task of the present invention is to provide a negative pressure air duct for the above-mentioned deficiencies in the prior art, which can effectively prevent the problems of easy bending and suction collapse under the negative pressure state. [0004] The technical solution adopted by the present invention to solve the technical problem is: the structure of this negative pressure air duct includes a cylinder body made of existing textile cloth, and the feature is that the outer surface of the cylinder body is along the axial directi...
