Description
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.
