Description

Electric curtain

The utility model relates to the opening and closing device of curtain in the daily life, particularly electrically driven curtain, once opening curtain automatically by switch; But press just auto-closing of switch again.

Curtain all was manually to draw curtain to open or close in the past.The photoelectricity automatic curtain was once arranged, though on have guide rail walker, pull rope, have and can reach daybreak along the clip of guide rail rolling wheel and just open curtain, darkness is just closed the purpose of curtain, complex structure on the one hand, cost height; Need to give signal on the other hand and just start, impracticable, so promote not open so far.What need in people's life is the moderate again electrically driven curtain that can bear of simple and flexible practicality.

The purpose of this utility model provides a kind of simple in structure, easy to operate, cheap again nimbly and freely electrically driven curtain.

The utility model is finished as follows: electrical installation is installed on walker, on the frame of this device dc motor is installed, its power supply is supplied with by electronic circuit board, on its output shaft belt pulley is installed, be connected with belt transmission with ratio wheel, being equipped with on coaxial with ratio wheel changes the line wheel, this take turns respectively with walker about two wire-crossing wheels be connected with pull rope, formation moves around, and a side is equipped with microswitch in the middle of walker.The switching of curtain is controlled by electrical installation.Electrical installation has transformer, on its primary wire switch is arranged, two groups of full-bridge type rectification circuits are arranged on the secondary wire, one group of output of this circuit is connected with the controllable silicon turning circuit, organizing output separately is connected with dc motor, there is relay to be electrically connected therebetween, constitutes the dc motor positive and reverse rotation control circuit.

The utility model has following advantage than conventional art: 1, simple in structure, cost is low; 2, easy to operate, nimbly and freely.

Further describe below in conjunction with accompanying drawing.

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

Fig. 2 is an electrical installation structure chart of the present utility model.

Fig. 3 is an electronic circuit schematic diagram of the present utility model.

With reference to Fig. 1, electrically driven curtain is made of walker (1), wire-crossing wheel (2), degree of tightness regulating block (3), pull rope (4), electrical installation (5), wire-crossing wheel (6), clip (7) and casement (8).Walker has guide rail on (1), has the clip (7) of wheel, can roll along guide rail and move.

With reference to Fig. 2, be electrical installation mounting structure figure, this device is installed on the walker (1).Dc motor (18) is installed on the frame of this device (14), and its power supply is supplied with by electronic circuit board (11).Belt pulley (17) is installed on the output shaft of motor, is in transmission connection with belt (16) with ratio wheel (15).Being equipped with on coaxial with ratio wheel (15) changes line wheel (13), and this is taken turns (13) and is connected with pull rope (4) with walker (1) left and right sides wire-crossing wheel (2) (6) respectively, and formation moves around, and one side is equipped with microswitch K in walker (1) centre ₂Electronic circuit board (11) also is installed on the frame (14).10 is transformer secondary output output inserter places among the figure, the 12nd, and K ₂Switch input plug-in unit.The 9th, the electric elements compoboard.

With reference to Fig. 3, electronic circuit and electrical schematic diagram in the electrical installation.The 220V AC power is passed through K ₁Insert the elementary of transformer B, two groups of full-bridge type rectification circuits are arranged on the secondary wire, one group of output is connected with the controllable silicon SCR turning circuit, and this circuit has C ₁, R ₁, R ₂, K ₂, SCR forms; Organize output separately and be connected, have relay J D to be electrically connected therebetween, constitute the dc motor positive and reverse rotation control circuit with dc motor.

In order to make the pull rope (4) can be all the time and the cooperating of wire-crossing wheel (2) (6), be added with degree of tightness regulating block (3) on it, adopt spring to make two ends rope tension.Walker (1) adopts aluminum alloy materials to make, and belt pulley (17), ratio wheel (15), commentaries on classics line wheel (13), wire-crossing wheel (2) (6) all are to adopt plastic injection-moulded forming.

In the circuit, B level of transformer 12V, commutation diode constitutes full-bridge type rectification circuit, C for two groups ₁, C ₂Be electrochemical capacitor 220 μ f/35V, resistance R ₁-300 Ω R ₂-1K, M one direct current motor, controllable silicon SCR, relay J D.K ₁It is normal open switch.K ₂Be microswitch, be placed on the curtain full close position, and inconsistent with the roller of clip (7) end.When casement (8) when setting, connect K ₁, motor is just changeing casement (18) and is moving to closing the position, then disconnects K during full cut-off ₁, press K again ₁The time, the roller and the K of clip (7) ₂Inconsistent and make K ₂Action, then controllable silicon conducting, relay J D work forwards positive potential to, the motor counter-rotating, casement (8) then moves to the position of opening.And can arbitrarily control the position that it is opened, when reaching maximum, then disconnect K ₁, this moment, controllable silicon was also at open-circuit condition.K ₁Can be connected into bigeminy, three or the tetrad switch, set up several places separately and carry out remote-controlled operation.
