Specific embodiment
The present invention is described in further detail below in conjunction with embodiment given by attached drawing.
Referring to Fig.1 shown in -6, a kind of wind-proof device of rolling screen door of the present embodiment, including curtain plate 1 and spool 2, it is described
The top of doorframe is arranged in spool 2, and for winding curtain plate 1, the back side of the curtain plate 1 is provided with two piece of first wind resistance plate 4, described
Two piece of first wind resistance plate 4 extends along the length direction of curtain plate 1 and two pieces overlapped, wherein can between two the first wind resistance plates 4
Relative rotation is provided with the first driver 5 on the position at 4 middle part of the first wind resistance plate, and first driver 5 has wind-force
Detection function, first driver 5 are set between the first wind resistance plate 4 and curtain plate 1, and have the first wind-force threshold value in it,
When the wind-force being applied on curtain plate 1 exceeds the first wind-force threshold value, first driver 5 drives two piece of first 4 phase of wind resistance plate
Fork configuration is formed to rotation, passes through the setting of spool 2, so that it may be packed up curtain plate 1, the back side of curtain plate 1 is provided with two pieces the
Primary antibody aerofoil 4, overlaps between each first wind resistance plate 4 and rotatable setting, and the first driver 5 is arranged on wind resistance plate,
First driver 5 and curtain plate 1 are inconsistent, when wind-force is excessive blows curtain plate 1, pass in the inside of the first driver 5 with pressure
Sensor, pressure sensor have pressure detecting function, when the wind-force being applied on curtain plate 1 is greater than the first wind-force threshold value, curtain plate 1
Deformation will be generated and drive squeeze pressure sensor, the wind-force being applied on curtain plate 1 is so detected by pressure sensor, in this way
When pressure sensor detects that wind-force is greater than wind-force threshold value, the first driver 5 drives two wind resistance plates to be rotated into X shape branch
Curtain plate 1 is supportted, prevents it from generating deformation, passes through the setting of the first driver 5, so that it may effectively detect wind-force, pass through two
The setting of first wind resistance plate 4, so that it may which effective support curtain plate 1 prevents its deformation, since a monolith curtain plate 1 is easiest to deformation
Position is in the middle position of curtain plate 1, by the setting that the first driver 5 is arranged in 4 center of the first wind resistance plate, so that it may effectively
Prevent curtain plate 1 generate deformation, so just will not be general compared with technology, since the wind resistance of curtain plate 1 is inadequate, and work as curtain plate 1
When meeting strong wind, curtain plate 1 can bend deformation, local notch be formed when serious, or even cause the destruction of curtain plate 1, wherein this
The signified back side refers to curtain plate 1 backwards to the face that wind comes in embodiment.
As a kind of improved specific embodiment, every the first wind resistance plate 4 is close on the position of its both ends end
Be provided with the second wind resistance plate 6, the second wind resistance plate 6 be overlapped with the first wind resistance plate 4 setting and can relative rotation, described first

6 relative rotation of the second wind resistance plate is driven, the second wind resistance plate 6 is provided on the position close to both ends end of the first wind resistance plate 4,
Under no external force, the first wind resistance plate 4 and the second wind resistance plate 6 are overlapped, when wind-force is more than the second wind-force threshold value, the second driving
Device drives the rotation of the second wind resistance plate 6 to keep the second wind resistance plate 6 vertical with the first wind resistance plate 4, by the setting of the second wind resistance plate 6, just
Wind resistance can be improved, pass through the setting of the second driver, so that it may drive the second wind resistance plate 6 to rotate, by the second wind resistance plate 6 with
First wind resistance plate 4 is overlapped setting, can reduce 6 occupied space of the second wind resistance plate.
As a kind of improved specific embodiment, the signal receiving/transmission device 14 includes transmitter 8 and receiver, described
Transmitter 8 is arranged inside the first driver 5, and the receiver setting is in the second internal drive, when wind-force exceeds the second wind
When force threshold, the transmitter 8 transmits signals to receiver, and the receiver controls the second driver, second driver
The rotation of the second wind resistance plate 6 is driven to constitute fork configuration with the first wind resistance plate 4, transmitter 8 is arranged inside the first driver 5, connects
Device setting is received in the second internal drive, when wind-force keeping out except range beyond the first wind resistance plate 4, transmitter 8 sends signal
To receiver, receiver drives the movement of the second driver, and the second driver drives the second wind resistance plate 6 to be rotated, and increases wind resistance
Performance, so by the setting of transmitter 8 and receiver, so that it may realize when the first wind resistance plate 4 be unable to hold out curtain plate 1 when
It waits, sending a signal to the second wind resistance plate 6 increases the rotation of the second wind resistance plate 6 by the wind resistance of curtain plate 1, prevents curtain plate 1 from generating shape
The phenomenon that change or bending.
As a kind of improved specific embodiment, first driver 5 includes first motor 15, the first gag lever post 16
With the second gag lever post 162, one end of first gag lever post 16 and the second gag lever post is fixedly connected with curtain plate 1, and the other end is equal
