Abstract

The utility model relates to a driving device for curtains; the primary structure is characterized in that a steel pipe driven by a motor is obliquely sheathed with a group of rolling bearings, wherein, the oblique direction and the pressing direction of the adjacent rolling bearings are rightly opposite. When the steel pipe rotates to one direction, the group of rolling bearings moves forward; when the steel pipe rotates to another direction, the group of rolling bearings moves backward. The driving device for curtains with light and novel structure is suitable for curtains in families, hotels and conference halls.

Description

The heavy curtain drive unit

The utility model relates to a kind of heavy curtain drive unit, particularly wireless drive unit, and structure comprises the curtain rod arm of Electric Machine Control.

Patent application about electrically driven curtain is existing multiple, as Chinese patent 96221527.9, and its structure more complicated, operation is difficult for.

The purpose of this utility model provides a kind of heavy curtain drive unit, and this device does need be used cable traction, do not need the screw thread transmission again, and tractive force is big, easy to operate.

The purpose of this utility model can be realized by following structure:

The steel pipe 1 of driven by motor tilts and is with one group of rolling bearing 2, all rolling bearings 2 are all identical with the angle of steel pipe 1 axis, adjacent rolling bearing 2 is opposite with the incline direction and the compression aspect of steel pipe 1, the rolling bearing 2 of being separated by is identical with the incline direction and the compression aspect of steel pipe 1, each rolling bearing 2 below all is fixed with a pedestal 3, and the pedestal 3 of being separated by is provided with the spiral shell that screw 4 penetrates under the rolling bearing 2 and buckles in 5.

The utility model also can be realized by following structure:

One group of rolling bearing 2 (one group of pedestal 3) is three at least.One group of pedestal 3 is contained in the shell 6, and pressing plate 8 with suspension ring 7 is being fixed by screw 4 in shell 6 belows.The two ends of steel pipe 1 are respectively bearing and motor, also are with suspension ring 7 on the steel pipe 1.

Effect of the present utility model and advantage are:

Principle of the present utility model is a rolling bearing 2 because screw 4 penetrates and tightens, thus adjacent rolling bearing 2 tilt to be enclosed within just form drop-down on the steel pipe 1 and on the effect that pushes away.At this moment the steel pipe 1 of driven by motor moves forward once rotating the relative steel pipe 1 of driving whole group rolling bearing 2 (comprising pedestal 3); If steel pipe 1 rotates round about, then rolling bearing 2 is corresponding mobile backward again.Suspension ring 7 and curtain are moved around.Heavy curtain driving device structure novelty, front and back drive freely brisk.It can make electrically driven curtain, the curtain that uses for family, hotel, conference hall and stage as required.

Description of drawings:

Fig. 2 is the front view of rolling bearing:

Fig. 3 is the vertical view of rolling bearing:

Below in conjunction with accompanying drawing for an embodiment:

As Fig. 1, shown in Figure 3, the steel pipe 1 of driven by motor tilts and is with one group of three rolling bearing 2, the rolling bearing 2 on both sides is identical with the incline direction of steel pipe 1, every rolling bearing 2 belows all are fixed with a pedestal 3, and the pedestal 3 on both sides is provided with the spiral shell that screw 4 penetrates under the rolling bearing 2 and buckles in 5.

As Fig. 2, shown in Figure 3, three pedestals 3 are contained in the shell 6, and pressing plate 8 with suspension ring 7 is being fixed by screw 4 in shell 6 belows.As shown in Figure 1, the two ends of steel pipe 1 are respectively bearing and motor, also are with suspension ring 7 on the steel pipe 1.

Claims
