Description

Opening and closing device for window curtain

The utility model relates to a kind of electrodynamic type curtain open/close device.

Electrically driven curtain box of the prior art be with box be one, complex structure, cost height.

The purpose of this utility model provide a kind of simple in structure, cost is low, can with the supporting use of mounted pelmet, the curtain open/close device that also can use separately.

The purpose of this utility model is to realize like this, on sheave, establish two grooves, pull rope one end can be in the other direction respectively on two grooves on the sheave, the pull rope other end can be on pulley, the rotating shaft of dress motor in the sheave, adorn fixed axis in the pulley, constitute a transmission mechanism, realize the folding of curtain.

Because the utility model is simple in structure, cost is low, easy for installation, on mounted pelmet, mix this curtain open/close device, just can realize the folding of curtain by press button.

Below in conjunction with accompanying drawing the utility model is described in detail.

Figure is the structural representation of curtain open/close device of the present utility model.

As shown in the figure, the utility model is made up of motor 1, sheave 3, pulley 6, pull rope 8.Motor 1 is the bidirectional reversible motor, can stipulate artificially that the control curtain was toward the direction motion of " opening " when motor 1 was just changeing, and the control curtain is toward the direction motion of " closing " during motor 1 counter-rotating.The rotating shaft 2 of motor 1 is equipped with in the centre of sheave 3, and fixed axis 7 is equipped with in the centre of pulley 6, and the outside of sheave 3 is provided with groove 4, groove 5, pull rope 8 is endless ropes, one end on the groove 4,5 of sheave 3 respectively in the other direction around, the other end is formed transmission mechanism thus on the groove of pulley 6, like this when motor 1 rotation, rotating shaft 2 drives sheaves 3 and rotates, and through pull rope 8 pulley 6 is rotated, groove 4 up wiring, groove 5 toward going out to put rope, the length of wiring just is the length of putting rope, reaches the purpose that drives curtain open/close.

During installation, curtain is to be contained on the pull rope 8, and pull rope is too not loose.Motor 1 is installed in the window two ends respectively with pulley 6, and angle can be free, if pulley 6 vertically installs, should with pulley 6 diameters big one upside down.

Claims (1)

1. A kind of curtain open/close device is made up of motor (1), sheave (3), pulley (6), pull rope (8) etc., it is characterized in that: sheave (3) is established groove (4,5), pull rope (8) one ends are oppositely respectively on the groove (4,5) on the sheave (3), the other end of pull rope (8) is on pulley (6), the rotating shaft (2) of dress motor (1) in the sheave (3), dress fixed axis (7) in the pulley (6).
