Description

Light-operated electrically driven curtain

Technical field:

The utility model belongs to the articles for daily use apparatus field, realizes the light-operated electrically driven curtain pull out or retract thereby relate in particular to a kind of rotation direction of controlling motor by light-operated switch.

Background technology:

Curtain is often to use one of commodity in the daily life, and it is widely used in many places such as family, school, office building, cinema.Modern curtain both can dim light, shading, to adapt to the needs of people to the light varying strength; Again can be windproof, dedusting, room weather and the environment of improving such as heat insulation, warming.

The curtain of Chu Shouing mainly is divided into common curtain and electrically driven curtain on the market.The drawing of common curtain needs manually-operated; Though electrically driven curtain has improved manually-operated trouble to a certain extent, but the structure of this class curtain is complicated, and, although do not needed directly manual drawing curtain, but still need manually carry out remote control or fixed cycle operator etc., especially in some special occasions, as the device storage chamber, if unmanned monitor the drawing of curtain constantly and cause daylight to being exposed to the sun for a long time of equipment, equipment is damaged, influence is normally used.

Summary of the invention:

The purpose of this utility model be to provide a kind of simple in structure, need not the light-operated electrically driven curtain that Artificial Control can be carried out drawing automatically, by light-operated switch turning to of motor controlled in the identification of intensity of illumination, thereby realize the automatic drawing of curtain, bring convenience to daily life.

For solving the problems of the technologies described above, the utility model adopts following technical scheme, and the utility model comprises light-operated box and pelmet, and light-operated box is connected by lead with pelmet, be provided with relay in the light-operated box of its structural feature, light-operated box surface is provided with light-operated switch, power switch and power line; Being provided with the fixed pulley that links to each other with motor in the pelmet, is the curtain rope with limiting plate on the fixed pulley; Pelmet inwall upper end is provided with and corresponding limit switch I of limiting plate and limit switch II.

Also can be provided with the curtain link on the curtain rope of the present utility model; Convenient fixing and pulling to curtain.

Light-operated switch described in the utility model, relay and motor link to each other successively by lead;

As a kind of preferred version, light-operated switch described in the utility model adopts HGK-10X.

The beneficial effects of the utility model:

Main member of the present utility model is light-operated switch, motor, two fixed pulleys, curtain rope and two limit switches, and is simple in structure, easy to operate; In the time of daybreak (when intensity of illumination is strong), light-operated switch disconnects, and relay control motor just changes, and curtain can be drawn back; In the time of darkness (when intensity of illumination is weak), the light-operated switch closure, the counter-rotating of relay control motor can be with the curtain closure; The utility model carries out drawing action by light-operated, need not manually-operated, time saving and energy saving; When disconnecting extraneous power supply, also can work as common curtain and use, satisfy different occasion people's needs.

Description of drawings:

The utility model is described in further detail below in conjunction with the drawings and specific embodiments.

Fig. 1 is a structural representation of the present utility model;

1 light-operated box, 2 light-operated switches, 3 relays, 4 power switches, 5 power lines, 6 leads, 7 pelmets, 8 motors, 9 limit switch I, 10 limiting plates, 11 curtain ropes, 12 curtain links, 13 limit switch II, 14 fixed pulleys;

Fig. 2 is a schematic block circuit diagram of the present utility model.

The specific embodiment:

As shown in Figure 1, the utility model comprises light-operated box 1 and pelmet 7, and light-operated box 1 is connected by lead 6 with pelmet 7, is provided with relay 3 in the light-operated box 1, and light-operated box 1 surface is provided with light-operated switch 2, power switch 4 and power line 5; Being provided with the fixed pulley 14 that links to each other with motor 8 in the pelmet 7, is the curtain rope 11 with limiting plate 10 on the fixed pulley 14; Be provided with in the pelmet 7 and limiting plate 10 corresponding limit switch I 9 and limit switch II 13.

Also can be provided with curtain link 12 on the curtain rope 11 of the present utility model; Convenient fixing to curtain.

As shown in Figure 2, light-operated switch 2 described in the utility model, relay 3 and motor 8 link to each other successively.

Light-operated switch 2 described in the utility model can adopt HGK-10X.

Below in conjunction with a description of drawings course of action of the present utility model:

The utility model disconnects and closure light-operated switch 2 by the brightness power of illumination; At first, press power switch 4 and connect external power source; In the time of daybreak (intensity of illumination is strong), light-operated switch 2 disconnects, forward is provided for motor 8 by relay 3, motor 8 drives curtain rope 11 beginning forward rotation curtain is drawn back, when curtain is fully withdrawn (when limiting plate 10 touches with limit switch I 9), limit switch I 9 disconnects, and motor 8 quits work; In the time of darkness (intensity of illumination is weak), light-operated switch 2 closures, provide reverse for motor 8 by relay 3, motor 8 drives curtain rope 11 beginning backward rotation curtain is closed up, when curtain closes up fully (when limiting plate and limit switch II 13 touch), limit switch II 13 disconnects, and motor 8 quits work.(also inverted machine 8 as required makes at day that curtain closes up, and curtain draws back at dark)

Give switch that motor 8 provides the forward electricity and motor 8 in a loop in limit switch I 9 and the relay 3, provide the switch of reverse electricity and motor 8 in a loop to motor 8 in limit switch II13 and the relay 3, these two loops are separate.

Though more than described the specific embodiment of the present utility model, but the those of skill in the art in the present technique field are to be understood that, these only illustrate, and can make numerous variations or modification to these embodiments, and not deviate from principle of the present utility model and essence.Scope of the present utility model is only limited by appended claims.
