Description
Technical Field
The utility model relates to the technical field of connecting ventilation hoses, in particular to a ventilation hose with a reinforced structure.
Background
In the extraction hood, often need the connecting pipe to carry out the bending, and among the coupling hose of prior art, interior outer wall is concave-convex structure, need fix with the help of clamp class part, carries out the chucking because of the clamp class, for increase of service life, needs increase the wall thickness, so bending resistance is big. In some hoses with good bending properties, the service life is reduced accordingly due to the wall thickness. The other hoses are provided with bulges, and the inner walls of the hoses are provided with uneven bulges and grooves due to consistent wall thickness of all parts, so that the wind resistance is increased, and the hose cannot meet the use requirement of an air exhaust cover which is often required to be bent.
SUMMERY OF THE UTILITY MODEL
The utility model aims to overcome the defects of the prior art and provide a ventilation hose which can be connected simultaneously and is provided with a reinforced structure which is not deformed after being bent frequently.
A ventilation hose with a reinforced structure comprises a hose body, wherein an inner cavity is arranged in the hose body, and the hose body is made of a high-temperature-resistant and corrosion-resistant soft non-metal material; the inner cavity is of a hollow smooth structure, and supporting parts which extend in the circumferential direction and are arranged at intervals are uniformly distributed on the outer circumference of the pipe body, so that the non-deformable 360-degree bending is realized; the supporting part and the pipe body are of an integrally formed structure, and the supporting part is of a spiral structure. The inside smooth structure that can not produce the windage, and 360 degrees bendings can not warp, and the supporting part of screw-tupe when connecting, has strengthened the structure of body, long service life is particularly suitable for being used in the part of extraction hood class.
As a further improvement and complement to the above solution, the present invention also includes the following additional technical features:
the supporting part is a bulge on the outer circumferential surface, and the structure is simple and reasonable.
The height of the bulge is 3-5 times of the wall thickness of the pipe body. Effectively increased intensity, just can carry out effectual support when realizing connecting.
The cross section of the bulge is square, rectangular, trapezoidal, triangular or arc-shaped, the structure is simple, and the use is convenient.
The hose is made of PP polypropylene, is corrosion-resistant, can resist the high temperature of 140 ℃, and has long service life and good comprehensive performance.
The utility model can achieve the following beneficial effects:
1. the utility model has reasonable structure, does not need other parts, can directly carry out threaded connection, and is convenient to connect, maintain and clean.
2. The strength has been strengthened when bellied setting is connected, can carry out frequent bending, and the performance can not influence, and intensity is good, long service life.
3. The sucked wind can not generate wind resistance.

Detailed Description
The following detailed description of embodiments of the utility model refers to the accompanying drawings.
As shown in fig. 1 to 5, the present invention is a ventilation hose of a reinforced structure.
The ventilation hose with the reinforced structure comprises a pipe body 1, wherein the pipe body 1 is of a cylindrical structure, an inner cavity 2 is arranged in the pipe body 1, and the pipe body 1 is made of a high-temperature-resistant and corrosion-resistant soft non-metal material; the inner cavity 2 is of a hollow smooth structure, the supporting parts 3 which extend in the circumferential direction and are arranged at intervals are uniformly distributed on the outer circumference of the pipe body 1, and the height of each supporting part 3 is higher than the outer circle of the pipe body 1, so that the pipe can be bent at 360 degrees without deformation; supporting part 3 and body 1 structure as an organic whole, just supporting part 3 be the screw-tupe structure, the spiral can be for levogyration or dextrorotation structure, control setting of revolve to can set up as required, corresponding setting can be carried out as required to the spaced distance equally.
Furthermore, the supporting portion 3 is a protrusion on the outer circumferential surface, and the bottom between the two protrusions is the outer circumferential surface of the tube body 1.
Further, the height of the bulge is 3-5 times of the wall thickness of the pipe body 1.
Further, the cross-sectional shape of the protrusion is square, rectangular, trapezoidal, triangular or arc, as shown in fig. 3-5, and the structure thereof may be any structure form suitable for connection in the prior art.
Furthermore, the hose is made of PP polypropylene, and the PP polypropylene has good comprehensive performance.
When the reinforced structure ventilation hose is used, the spiral protrusions can be directly connected in a threaded manner, or parts such as connecting sleeves can be used for connection.
The above is the preferred embodiment of the present invention, and the scope of the present invention is not limited thereto, and variations and modifications made by those skilled in the art according to the design concept of the present invention should be considered to be within the scope of the present invention.
