Description

Electric curtain machine

The utility model relates to the electronic closing device of curtain.

Along with the raising of family and travelling indoor decoration level, electric controller for curtain is used gradually.At present electric controller for curtain has multiplely, wherein a kind of by a fixable main frame, and window curtain driving mechanism that the window curtain driving mechanism that drive, support and console switch are formed is made up of two main frames or the curtain mechanism of being made up of the main frame that moves on Curtain rail are simple and practical.But this window curtain driving mechanism in the prior art, the electric control theory complexity, employing is contained in power switch, the band switch in the console switch and is contained in the control that limit switch on the main frame is realized direct current generator commutation rotation and curtain open/close, need during operation could realize opening of curtain or unify an action through twice manual activity, and can only open fully or close, can not arbitrarily be parked in a certain position, so the folding curtain is cumbersome, dumb.On the other hand, this window curtain driving mechanism makes it cooperate dislocation to make curtain open/close not in place with limit switch owing to sliding appears in pull rope and pulley room sometimes, especially is not suitable for being used for the thick bunting curtain of matter.The gear graduation of this window curtain driving mechanism wiring of prior art, complex structure, employing copper, two kinds of materials of nylon, nylon gear are not lacked with oil lubrication, service life, and last two factors also make cost improve.

It is reasonable that the purpose of this utility model provides a kind of electric control theory, and the folding curtain is easy and simple to handle, flexible, reliable, be suitable for the matter overdrape, electric wiring simple structure, long service life, the window curtain driving mechanism that price is suitable.

The utility model is achieved in that it comprises: can fix main frame on the wall, can fix on the wall driven pulley, electric control system, console switch by fixed mount.Wherein a main frame main driving wheel of going up, be positioned at housing exterior by the axle that is contained in direct current generator, gearbox, the transformer in the insulation crust and is contained in gearbox is formed, and it is used to drive the pull rope that draws curtain; Also comprise and to be used for the pull rope of transmission traction curtain by the fixing driven pulley on the wall of fixed mount; Also have console switch, it comprises insulation crust, shell bottom plate, power switch, and it is used to operate the folding of curtain.Characteristics of the present utility model are: (a), electric controling line route 220V power supply, transformer, switch element, rectifier cell, direct current generator form the loop of two parallel connections, article one, the loop is the input that the zero line of 220V power supply connects transformer, live wire through switch element 4, transformer input, the public end 15 of output, rectifier cell 16, switch element 5, motor 18 to transformer output 19; Another loop is that the zero line of 220V power supply connects the transformer input, the live wire that connects switch element 4 is with switch element 4 and connect switch element 6, again through transformer input, the public end 15 of output, with above-mentioned loop in rectifier cell 16 oppositely be connected in rectifier cell 17 in the loop, switch element 7, motor 18 to transformer output 19.(b) console switch also comprises: two can make two switch elements 4 in same loop and the insulation button 2 and 3 of 5 or 6 and 7 foldings simultaneously respectively: be installed in four switch elements (4,5,6,7) and corresponding four contacts 9 on the wiring board 11, be connected in two shunt circuits and be installed in rectifier cell 16,17 on the wiring board 11 with opposite direction; Two button spring 8.

Fig. 1, Fig. 2, Fig. 3, Fig. 4 are embodiment of the present utility model.

Fig. 1---be electric control theory figure

Fig. 2---be the console switch front view

Fig. 3---be the console switch vertical view

Fig. 4 (a, b)---be electric controller for curtain scheme of installation (front view, vertical view)

Embodiment is elaborated to the utility model below in conjunction with accompanying drawing.

Among Fig. 1, Fig. 2, Fig. 3, Fig. 4,1-is that insulation crust, 2-button, 3--button, 4,5,6,7-are metal spring sheet switch, 8-spring, 9-contact, 10-fixed leg, 11-wiring board, 12-shell bottom plate, 13-alignment pin, 14-button support column, the input of 15-transformer, exports public end, 16-diode, 17-diode, 18-direct current generator, 19-transformer output, 20-main frame, 21-main driving wheel, the driven wheel carrier of 22-, 23-driven pulley, 24-console switch.

Described electric controller for curtain, its console switch adopts three heart yearns to connect with power supply, transformer and direct current generator.Its console switch comprises the plastic casing (1) that button 2 and 3 can be installed, and the center has plastic button (2) and (3) of support column.Support column and button injection moulding and be molded into one, two springs 8 are contained in respectively in the support column of button 2 and 3, and spring 8 and wiring board 11 contact jaws are by 13 location of the alignment pin on the wiring board.Plastic button 2 and 3 be sized and shaped as push button the time, each button all can press down two switch elements 4,5 or 6,7 in same loop simultaneously.Its switch element is a metal spring sheet switch.Support column 14 bottoms contact with wiring board 11 during push button; define button and move down distance; it moves down distance and just in time equals at button not under the duty; support column is apart from the distance of wiring board; after depending on the metal spring sheet and the contact contacts, it allows the optimum distance that presses down, to guarantee the reliability that metal spring sheet switch 4,5,6,7 uses and to protect its service life.Described rectifier cell 16 and 17 is diode, and 16,17 differential concatenations oppositely are installed on the wiring board 11 during installation in loop separately in two shunt circuits.It is the tool rectified action in control circuit, has played the effect that makes direct current generator commutation rotation again.Shell bottom plate 12 usefulness screws by with shell be that holistic fixed leg and shell 1 are fixed together.During operation, 2 of press push button are connected the loop of metal spring sheet switch 4,5, diode 16, direct current generator, and motor is rotated to a direction, make curtain close (or opening) by speed change and transmission device (through-drive wheel and pull rope).When press push button 3, then connect metal spring sheet switch 6 and 7, the loop of diode 17 and direct current generator is rotated direct current generator in the opposite direction, makes curtain open (or closing) by speed change and transmission device.The gear of described electric controller for curtain, gearbox is the oil resistant plastics gear.The size of its host housing can be 77 * 55mm, adds that fixing is 100 * 55mm with shell edge.The console switch shell sizes can be 75 * 30mm.As shown in Figure 4, main frame 20 is fixed on the wall of window one side by the fixing hole on the host housing edge during installation.Driven pulley 23 is fixed into one with driven wheel carrier 22, is fixed on by the hole on the driven wheel carrier on the wall of window opposite side.Pull rope is around master and slave drive, and reasonably connects with the ring of hanging curtain.

The utility model has following beneficial effect
