The roller 11 being placed in the shell 10,2 upper end of curtain are connect with the roller 11, and lower end is connect with the weight linear meter 3,
Roller 11 is by the power device driving being arranged in shell 10, and power device can be motor or motor and transmission mechanism cooperates；
It is provided with hairbrush 13 before and after in the outlet of 10 downside of the shell, the hairbrush 13 of two sides is oppositely arranged, and the curtain 2 is from two sides
It passes through between the bristle of hairbrush 13, is entered in wrap-up 1 with the dust for stopping 2 front and back of curtain to adsorb.
When winding curtain 2, roller 11 is rolled curtain volume 2 on 11 surface of roller, and the dust on 2 surface of curtain passes through shell 10
The blocking of hairbrush 13 of two sides is removed in the outlet of downside, and dust is avoided to enter in shell 10, simultaneously as the front of curtain 2 and
The dust at the back side is removed, and can be rolled up when on roller 11 to avoid curtain 2, and the dust pollution curtain 2 at 2 back side of curtain is just
Face；When releasing curtain 2, it due to 2 surface free from dust of curtain, will not stop that dust is caused to gather in shell 10 because of hairbrush 13.
In the present embodiment, the bristle of the hairbrush 13 is horsehair, and horsehair softness is fine and closely woven, will not damage 2 surface of curtain, and hinder
It is good to keep off dust effect.
Embodiment 2
A kind of dust-proof screen device of the present embodiment, basic structure is different and the improvement is that with embodiment 1, such as Fig. 3
Shown, described 11 one end of roller is fixedly connected with the motor 15 being arranged in the shell 10, and the other end and setting are described outer
Bearing 14 in shell 10 is rotatablely connected, and the motor 15 and bearing 14 are separately positioned on both ends in shell 10.After motor 15 starts
It drives roller 11 to roll, and then realizes 2 automatic deploying and retracting of curtain, it is easy to use.
In the present embodiment, the motor 15 be permanent magnet synchronous motor, have the small in size, long-life, highly reliable, low noise and
The advantages that low vibration, can reduce noise when wrap-up 1 is run.
Embodiment 3
A kind of dust-proof screen device of the present embodiment, basic structure is different and the improvement is that with embodiment 1 or 2, such as
Shown in Fig. 1, directive wheel 12 is additionally provided in the shell 10, the directive wheel 12 is positioned close to going out for 10 downside of shell
At mouthful, and it is located at 2 lower section of curtain.
Directive wheel 12 is used to prop up on the curtain 2 in the outlet for being located at 10 downside of shell, avoids the front of curtain 2 and shell 10
Seamed edge contact in the outlet of downside to avoid the positive surface wear of curtain 2, while avoiding hair of 2 excessive compression of curtain on front side of it
It brushes 13 and hairbrush 13 is caused to damage.
Embodiment 4
A kind of dust-proof screen device of the present embodiment, basic structure is any with embodiment 1 to 3, and different and improvements exist
In being respectively connected with lifting rope 7 on the hanging ring 6 as shown in Fig. 2, being provided with several hanging rings 6 on the upside of the wrap-up 1.Installation is anti-
When dirt screen device, 7 upper end of lifting rope need to be only fixed on to roof, wrap-up 1 is suspended on 7 lower end of lifting rope by hanging ring 6,
It does not need to support using bracket, it is at low cost, and it is not take up stage space after the installation is completed.
In the present embodiment, the quantity of the hanging ring 6 is 5, and is uniformly distributed from 1 middle part of wrap-up to both ends；It is described
Lifting rope 7 is wirerope, and intensity is high, durable and at low cost.
Embodiment 5
A kind of dust-proof screen device of the present embodiment, basic structure is any with embodiment 1 to 4, and different and improvements exist
In as shown in Fig. 2, the left and right sides of the curtain 2 is symmetrically arranged with side rope 5, the left and right side of the side rope 5 and the curtain 2
It is connected between edge by several elastic strings 4, the both ends of elastic string 4 are fixedly connected with the edge of curtain 2 and side rope 5 respectively, this reality
It applies in example, after curtain 2 is put down, the elastic string 4, which is tightened up, to be in a horizontal state；5 upper end of side rope is connect with roller 11, under
End is connect with the weight linear meter 3, and when using 1 folding and unfolding curtain 2 of wrap-up, for side rope 5 together by folding and unfolding, weight linear meter 3 can be tension
Side rope 5 and elastic string 4 provide counterweight.
In the present embodiment, the elastic string 4 is elastic string, is easy to obtain, and cheap；The longitudinal direction of the hairbrush 13 is long
Degree is of same size with the cloth cover of curtain 2, and hairbrush 13 and elastic string 4 is avoided to interfere and elastic string 4 is hindered to pass in and out shell 10.
When folding and unfolding curtain 2, weight linear meter 3 drops naturally, and curtain 2 is made to be tightened up flattening due to by downward pulling force；Counterweight simultaneously
Bar 3 can tense the side rope 5 of the left and right sides of curtain 2, and side rope 5 holds the elastic string 4 at 2 edge of curtain two sides horizontal stretching to the left and right,
The pulling force of left and right directions is provided for curtain 2, by its tensioning spreader in the lateral direction.
Dust-proof screen device in the present embodiment is cooperated by weight linear meter 3, side rope 5 and elastic string 4, can simultaneously be curtain
Cloth 2 provides upper and lower and left and right directions pulling force, makes its tensioning spreader around；Due to using several bullets between side rope 5 and curtain 2
Property rope 4 connect, in folding and unfolding curtain 2,4 end of elastic string will not generate displacement relative to side rope 5 and curtain 2, can be to avoid bullet
The phenomenon that property rope 4 is gathered, and then prevent curtain 2 from partial relaxation out-of-flatness occur and influencing drop shadow effect；Curtain is avoided simultaneously
2 surface folding of cloth causes to interfere when folding and unfolding with hairbrush 13.
Embodiment 6
A kind of dust-proof screen device of the present embodiment, basic structure is different and the improvement is that with embodiment 5, such as Fig. 2
Shown, the elastic string 4 is uniformly distributed from top to bottom, so that elastic string 4 is uniform from top to bottom to the pulling force of 2 left and right sides of curtain
Distribution avoids between 2 edge partial elastic rope 4 of curtain spacing is excessive from leading to region cloth cover relaxation and can not flatten.It is described
The elastic string 4 of 2 left and right sides of curtain is symmetrical arranged, so that pulling force suffered by 2 left and right sides of curtain is symmetrical, avoids two side draws
It is not reciprocity to cause the inclination of curtain 2, surface deflections.The elastic string 4 differs in length, and by 2 middle part of curtain to upper and lower ends
The length of elastic string 4 be gradually increased so that curtain 2 forms the arc to 2 lateral bend of curtain, side rope 5 in the middle part of side rope 5 after flattening
Both ends are tended in the state of being straightened by pulling force, and the pulling force being subject to positioned at the elastic string 4 of curtain 2 middle part to upper and lower ends is in uniform
The micro variation weakened, so that curtain 2 gradually relaxes from intermediate both ends lower upwards, the mistake for preventing curtain 2 from being drawn by upper and lower ends
It is tight and cause to occur partial relaxation in the middle part of it can not to flatten.
Schematically the utility model and embodiments thereof are described above, description is not limiting, attached drawing
Shown in be also one of the embodiments of the present invention, actual structure is not limited to this.So if this field
Those of ordinary skill enlightened by it, without deviating from the purpose of the present invention, not inventively design
Frame mode similar with the technical solution and embodiment, all should belong to the protection range of the utility model.
