Abstract

The utility model provides a rolling curtain device, which comprises a bracket, a bearing, a central axis, a piece of cord fabric and a lower rod. Both ends of the central axis are respectively provided with pull ropes with the opposite winding direction, to control the elevation and subsidence of the cord fabric. The basic difference between the device and the existing curtains is that the device uses the straight reel to roll up curtains.

Description

Curtain winding device

The utility model relates to a kind of roller blind device, especially a kind of straight spool roller blind device.

Existing curtain all is to adopt the pull wire pulley device, and mostly is horizontal open and close that its sealing effectiveness is not good basically.Though the blind window outward appearance is better, its sealing effect is poor, weight is also big.

The purpose of this utility model is to provide a kind of roller blind device above-mentioned defective, that serve many purposes in the prior art that overcome.

The purpose of this utility model is achieved in that this roller blind device is made up of support, bearing, axis, cord and lower beam, the two ends of axis by bearing fixing on support, two ends at axis respectively are provided with a V-shaped groove, the stay cord of reverse coiling is housed respectively in V-shaped groove, the upper end of cord is fixed on the middle part of axis by sheet metal, lower beam is equipped with in the lower end of cord, also is provided with handle on the lower beam.

The utility model has the advantages that: adopt this device roller shutter, good sealing effect, opening and closing are all easily reliable.This roller blind device is simple in structure, and is cheap, and dependable performance, can make the be subjected to light and the worn-out light of window reach optimum degree, and can be used for multiple occasion.

Fig. 1 is a kind of form of the utility model roller blind device;

Fig. 2 is the schematic diagram of axis outer cover;

Fig. 3 is the another kind of form of the utility model roller blind device;

Fig. 4 is the another kind of version of lower beam 9 among Fig. 1;

Fig. 5 is the groove that is applicable to the design form among Fig. 4.

Describe the utility model in detail below in conjunction with accompanying drawing.

As shown in Figure 1, roller blind device of the present utility model comprises support 1, bearing 2, axis 4, cord 7 and lower beam 9.The two ends of axis 4 are fixed on the support 1 by bearing 2, respectively are provided with a V-shaped groove 3 at the two ends of axis, and the stay cord 6 of reverse coiling is housed respectively in the V-type groove, rising, falling with control cord 7.When a stay cord unwinding, drive axis 4 and rotate, simultaneously another root stay cord is wound in the corresponding V-shaped groove, like this, can realize rising, falling of cord by two stay cords.The upper end of cord 7 is fixed on the axis 4 by sheet metal 5, and lower beam 9 is equipped with in the lower end of cord, has also set up handle 8 on lower beam 9.But it is the outer cover shown in the installation diagram 2 10 also above axis 4, so that dustproof.

As shown in Figure 3, on the basis of roller blind device shown in Figure 1, also axis 12 in can be set abreast in the inboard of axis 4, interior axis is fixing by inner support 13 in the same way.The yarn curtain is housed on interior axis, and the coiling direction of cord is opposite on the coiling direction of yarn curtain and the axis 4, in the proximal end of axis and interior axis pitch wheel 11 and 18 is housed respectively, and like this, when rolling cord, the yarn curtain just lowers simultaneously.

Fig. 4 is an another kind of embodiment of the present utility model, is with the difference of installing among Fig. 1, and a little bearing 14 respectively is housed at the two ends of lower beam 9, and little bearing is fixing by screw 15, at the middle part of lower beam one clamping type is housed also and bumps pearl 16, is used for fixing lower beam.Adapt with this design, one Qian connected in star 17(is installed referring to Fig. 5) in the both sides and the bottom of cord.Lower beam is by bearing upper and lower moving in groove at two ends.

The utility model roller blind device also can be used for indoor next door, stage background, darkroom and bathtub and locates every curtain etc. except that can be used for curtain, and therefore, its purposes is very extensive.

Axis and lower beam can be made with timber, and also the available metal material is made, and the Qian connected in star can be made with aluminium alloy.
