Abstract
The utility model discloses a portable telescopic air duct in a simple structure. The portable telescopic air duct is composed of five modules as follows: a round disc (1), a screw rod (2), a telescopic pipe (3), a corner butting piece (4) and a frequency converter end interface (11). The telescopic is sleeved on a telescopic sleeve of the round disc and is then fixed by bolts. After the fixing is finished, the screw rod is used for butting through a screw hole so as to fix the air duct. The air duct is connected at a corner through the corner butting piece. A special frequency converter end interface is arranged at a connecting end of the air duct and a frequency converter.
Description
Affiliated technical field
The utility model relates to a kind of portable stretchable air channel, belongs to the supporting ventilation duct of frequency variator.
Background technique
At present, the ventilation duct of frequency variator all be after frequency variator installs again as required length dimension use the iron sheet installation and processing.This just requires after the frequency variator installation, again the installation of frequency variator find suitable material and processing stand to process at present, the not only complicated difficult operation of dismounting but also increased the installation period of equipment, inconvenience very.
Summary of the invention
In order to overcome existing frequency variator ventilation duct dismounting inconvenience, existing with existing processing, increase the deficiency of equipment installation period, the utility model provides a kind of portable stretchable air channel simple in structure.Wind channel tube adopts the familiar PVC telescopic pipe, and the telescopic pipe periphery is fixed with screw rod and disk, and is soft to overcome flexible pipe structure, is prone to sagging problem.
The utility model solves the technological scheme that its technical problem adopted: this portable stretchable air channel is made up of five part of module: disk, screw rod, telescopic pipe, the interfacing part that turns round, frequency variator end interface.Telescopic pipe is set on the sheathed tube of telescopic pipe of disk, uses bolt then.After fixing the completion, through the screw hole butt joint, play fixation with screw rod.The corner gets final product through the interfacing part connection of turning round.The connecting end of air channel and frequency variator is furnished with special-purpose frequency variator end interface.Each several part module volume is little, and convenient transportation has increased the convenience that transportation is installed greatly.
The beneficial effect of the utility model is, the actual demand that can install according to the frequency variator air channel utilize ready-made module assembling to get final product, and installs very convenient, simple in structure.
Portable stretchable air channel as stated, wherein, telescopic pipe adopts the familiar PVC telescopic pipe, and is scalable.
Portable stretchable air channel as stated, wherein, disk adopts glass fibre reinforced plastics processing, is made up of disk and sheathed tube (5), has the screw hole (7) that the fixedly bolt hole of telescopic pipe (6) and screw rod dock.
Portable stretchable air channel as stated, wherein, screw rod adopts casting heart iron pipe, and two ends are respectively bolt end (8) and bolt slot (9).
Portable stretchable air channel as stated, wherein, the interfacing part that turns round (4) adopts glass fibre reinforced plastics processing.
Portable stretchable air channel as stated, wherein, frequency variator end interface (11) adopts glass fibre reinforced plastics to process, and sheathed tube diameter calculates according to the long-pending principle that equates with the fan outlet sectional area of duct cross-section.
