Abstract

The utility model relates to a light controlled automatic curtain machine. A photoreceptor is connected with a control box by an electric wire; the control box is connected with a limit switch by an electric wire; the limit switch is connected with a conducting wire machine by an electric wire; the conducting wire machine is connected with a pulley by a drawing rope; a switch bumping device is fixed to the drawing rope; a curtain clamp is arranged on the drawing rope. The utility model automatically opens and closes according to the light strength, and can be opened or closed by hands; the sensitive light strength can be adjusted. The utility model has the advantages of simple structure, high sensitivity, and labor saving.

Description

Light-operated automatic curtain machine

The utility model relates to a kind of window curtain driving mechanism, specifically is a kind of light-operated automatic curtain machine.

Existing window curtain driving mechanism all is an electric controller for curtain, uses the hand control switch, open morning, evening closure, its shortcoming is to need the people to control.

The purpose of this utility model provides a kind of light-operated automatic curtain machine, and it can not only be experienced, and light is opened automatically, closure, and can open with hand control, closure.

The purpose of this utility model is achieved in that

Photoreceptor links to each other with control box by electric wire, and control box links to each other with limit switch by electric wire, and limit switch links to each other with the lead machine by electric wire, and the lead machine links to each other with pulley by pull rope, and switch hits son and is fixed on the pull rope, and curtain clip is placed on the pull rope.

In morning, light is strong, and photoreceptor output photoelectric current makes two electric wires connections in the control box, and lead machine positive direction is rotated, and pull rope and then rotates, curtain opening, and when complete opening, switch hits son and runs into limit switch, and circuit disconnects, and the lead machine stops operating; In evening, light is dark, and photoreceptor shows very big resistance, two electric wires in addition in the control box are connected, lead machine counter-rotation, pull rope is counter-rotation also, the curtain closure, when complete closure, switch hits son and runs into limit switch, and circuit disconnects, and the lead machine stops operating, in the time will opening curtain in advance, can make photoreceptor shift to an earlier date sensitization; In the time will shifting to an earlier date closed curtain, can make photoreceptor show very big resistance.

The utility model is simple in structure, and is highly sensitive, and light is control and manual dual control automatically.

In Fig. 1, photoreceptor (1) is installed in outside window, experience light, control box (3) connects power supply, picks out 8 electric wires (2) in addition again, article 4, photoreceptor (1) even, article 4, link to each other with lead machine (5) by limit switch (4), lead machine (5) links to each other with pulley (7) by pull rope (6), and switch hits son (8) and is fixed on the pull rope (6), curtain clip (9) is placed on the pull rope (6), and curtain (10) is hung on the curtain clip (9).

Fig. 2 is circuit theory diagrams, under the normal condition, and K ₁, K ₂As shown in the figure, in morning, light is strong, injects phototriode (BG ₁) light strong, BG ₁Be switched on, export certain photoelectric current, make triode BG ₂Base stage and emitter stage between approximate short circuit, BG ₂Be cut off, between its colelctor electrode and the emitter stage higher voltage arranged, this voltage passes through resistance R ₅Be added to triode BG ₃Emitter stage on, BG ₃Conducting is like this at triode BG ₃Relay J adhesive in the collector loop, normally-closed contact disconnects, and lead machine (5) positive direction is rotated, and after limit switch (4) disconnected, lead machine (5) stopped operating; Evening, a little less than the light, phototriode BG ₁The very big resistance of inner demonstration does not have photoelectric current output, BG ₂Conducting, BG ₃Be in cut-off state, so relay J is released, another group power line of the motor on the normally-closed contact is switched on lead machine (5) counter-rotation.When K ₁By arriving the other end, bulb ZD is luminous, BG ₁Sensitization, lead machine (5) positive direction is rotated; When K ₂By arriving the other end, R ₈With BG ₁Form very big resistance, lead machine (5) counter-rotation.

Among Fig. 3, motor (11) connects axostylus axostyle (12), and change-speed gearing (13) is fixed on the axostylus axostyle (12), and circle wheel (14) is fixed on the axostylus axostyle (12), and motor (11) rotates, and after change-speed gearing (13) speed change, circle wheel (14) and then rotates.

Fig. 4 is the photoreceptor cut-away view, is made up of phototriode BG1 and bulb ZD.

Fig. 5 is the control box external structure, by switch (K ₁, K ₂, K ₃) and knob (15) composition.

Fig. 6 is the control box cut-away view, by voltage-stabilized power supply (D1-D ₅, C, R ₇), triode (BG ₂, BG ₃), relay (J) resistance (R ₁, R ₂, R ₃, R ₄, R ₅, R ₆, R ₈) form, resistance (R1) is with respect to the knob in the control box external structure (15), the power that is used for regulating sensitization.
