Abstract
The utility model relates to a vent pipe which can be folded in a helical way. The longitudinal section of the pipe wall is wave-shaped. The vent pipe is characterized in that the pipe is formed by helically winding and bonding belts of a flame-retardant composite aluminum foil PVC material; and a helical steel-wire support is arranged in the interlayer of the winding and bonding part of the pipe. The vent pipe has long service life, wide application range and high supporting capacity of the pipe wall, thus being not easily deformed and particularly suitable for being used as air ducts of an air conditioner or a range hood.
Description
Technical field
The utility model relates to a kind of ventilation duct, specifically a kind of ventilation duct that is applied to equipment such as kitchen ventilator, ventilating fan and air-conditioning.
Background technique
At present kitchen ventilator, ventilating fan and air conditioner ventilation pipeline etc. mostly are common plastics tube, easy deformation not only, and wear out than being easier in use for some time, influence working life.And this plastic tube can't fold, and transportation and installation be trouble comparatively, can't in time change its length according to the actual needs, and influence is used.
Summary of the invention
The purpose of this utility model then is at present the deficiencies in the prior art, and a kind of folding convenient is provided, and is not yielding, the ventilation duct of long service life.
The technical solution adopted in the utility model is as follows:
A kind of ventilation duct, but be the collapsible pipeline of spiral, and the longitudinal section undulate of its tube wall is characterized in that described pipeline twines bonding by clad aluminum foil flame-proof PVC material band spiral and forms, and is provided with spiral wire and supports in the interlayer of the winding bonding part of pipeline.
Described clad aluminum foil flame-proof PVC material band is the double layer construction that aluminium foil and flame-proof PVC material are combined into, and skin is an aluminium foil, and internal layer is the flame-proof PVC material; The tube wall of spiral wire support place is four-layer structure on the pipeline.
Described spiral wire supports crest or the trough place that is positioned at the waveform tube wall.
Described spiral wire is coated with one deck flame-proof PVC material on supporting.
The diameter that described spiral wire supports is 0.5～3.0mm.
The diameter that described spiral wire supports is 1.0mm.
The beneficial effects of the utility model have:
Long service life, applied range, the enabling capabilities of tube wall is strong, thereby not yielding, is especially suitable for use as the ventilation duct of air-conditioning and kitchen ventilator.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is one of sectional view of the utility model spiral wire support place.
Fig. 3 be support place of the utility model spiral wire sectional view two.
Fig. 4 is the structural representation of the utility model after folding.
Fig. 5 is a cross section structure schematic representation of the present utility model.
Embodiment
The utility model is further described below in conjunction with accompanying drawing:
Shown in Fig. 1-5, but the utility model collapsible pipeline that is spiral, the longitudinal section undulate of its tube wall, can stretch the ventilation duct that becomes to need during use, being installed to the exhaust outlet of air-conditioning or range hood. the utility model pipeline twines bonding by clad aluminum foil flame-proof PVC material band spiral and forms, when twining bonding, spiral wire is supported 2 to be placed in the winding bonding part interlayer of pipeline 1, make pipeline not yielding, increasing the service life. spiral wire support 2 is positioned at the crest or the trough place of waveform tube wall, its diameter range is 0.5～3mm, uses diameter can make the versatility of pipeline best as the steel wire of 1mm.
Clad aluminum foil flame-proof PVC material band in the utility model is the double layer construction that aluminium foil and flame-proof PVC material are combined into, and skin is an aluminium foil, and internal layer is the flame-proof PVC material, and the tube wall that makes spiral wire on the pipeline 1 support 2 places like this is four-layer structure.Can also support at spiral wire as required and be coated with one deck flame-proof PVC material on 2, to adapt to some special occasions needs.
Other undeclared part that the utility model relates to is same as the prior art.
