Description
Technical field
This utility model is related to a kind of window-blind draw off gear, and in particular to a kind of computer and automated teaching shading
Curtain draw off gear, belongs to computer and automated teaching field.
Background technology
During computer and automated teaching, it is often necessary to carry out projection demonstration teaching using multimedia equipment, projection
In presentation process, in order that student can be clearly visible that presentation process, need the window shade of teacher.However, existing
Have teacher's window using window-blind be common fabric curtain, during use, naturally droop shield window by its own gravity
Mouthful, however, when there is wind to be blown into interior outside window, curtain will be blown afloat and cannot cover window, if by the sash of window
Close, can cause classroom interior air-flow obstructed again, make student and teacher produce feeling of oppression and heat.
Utility model content
This utility model is fabric curtain to solve existing window-blind, runs into outdoor airflow and is blown into curtain and will be blown afloat
And window cannot be covered, if the sash of window is closed, can cause classroom interior air-flow obstructed again, produce student and teacher
The problem of feeling of oppression and heat, and then propose a kind of computer and automated teaching window-blind draw off gear.
This utility model is adopted the technical scheme that to solve the above problems：This utility model includes reel, spool, spool
Motor, the first synchronous motor, the second synchronous motor, window-blind, the first rope folding and unfolding cylinder, the second rope folding and unfolding cylinder and two
Rope, reel are horizontally fixed at the top of window inner side, and spool is horizontally set in reel, one end of spool be arranged on outside reel
Reel motor rotary shaft connection, the top margin of window-blind is fixedly connected with spool, the first synchronous motor and the second synchronous motor
The bottom of window inner side is arranged on, the first rope folding and unfolding cylinder is sleeved in the rotary shaft of the first synchronous motor, the second rope is received
Put cylinder to be sleeved in the rotary shaft of the second synchronous motor, two angles on window-blind base are restricted with first respectively by two ropes
Rope folding and unfolding cylinder and the connection of the second rope folding and unfolding cylinder.
Further, this utility model also includes negative-pressure air fan, dust collecting bin, main negative-pressure air duct, drainage screen and multiple
Branch's negative-pressure air duct, main negative-pressure air duct are collected with dust by multiple branch's negative-pressure air ducts and UNICOM in reel, main negative-pressure air duct
The dust collection port connection of case, the negative pressure air port of dust collecting bin is connected with negative-pressure air fan, at the negative pressure air port of dust collecting bin
It is provided with drainage screen.
The beneficial effects of the utility model are：1st, the bottom of window-blind is fixed by this utility model by two ropes, disappears
When being blown into except outdoor airflow, window-blind cannot cover the problem of window, meanwhile, also avoid closing indoor air flow caused by sash
Slack problem；2nd, the bottom of window-blind of the present utility model is synchronous with the first synchronous motor and second electric by two ropes
Machine connects, and when needing to launch window-blind, teacher is only needed to using remote control from the first synchronous motor of distant control and second
Synchronous motor is opened, you can window-blind is launched masking window, and after finishing, teacher is rolled up from distant control using remote control
Spindle motor then can be taken in window-blind in reel, convenient to operation, effectively improve classroom teaching efficiency；3rd, it is of the present utility model
It is connected with dust collecting bin in reel, after starting negative-pressure air fan, then under the negative pressure wind effect of negative-pressure air fan, the dust quilt in reel
In suction dust collecting bin, the cleaning of window-blind is effectively ensured, it is to avoid the dust splashed during window-blind folding and unfolding affects to learn
Raw and teacher's is healthy.
