Description

Electric movable curtain

The utility model relates to a kind of electric controller that curtain opens and closes of controlling, and it also is applicable to the keying control of stage curtain.

At present, the form of electrically driven curtain is varied, but its structure is identical substantially, all nothing more than being to be made of fixed support, backguy, hanging wire, leading block, slip ring, driving wheel, driven pulley, motor, gauge tap and institutes such as control circuit and cord thereof.The audio device that has additional the doorbell of holding concurrently is also arranged.Yet these curtain all must be pressed the button of gauge tap continuously when opening and closing, otherwise curtain just stops to move.

The purpose of this utility model provides the button that a kind of need press gauge tap just can make curtain open automatically or close, and has the sound equipment of double doorbell and represent the indoor people of having or the electrically driven curtain of unmanned display.

Technical solution of the present utility model is: existing electrically driven curtain is improved.The gauge tap of soon pressing continuously changes the sticking relay switch into, and on existing electrically driven curtain, have additional and start capacitor and the double-point double-throw switch that is connected with backguy and sticking relay switch, motor, startup capacitor, the control circuit of double-point double-throw switch, attaching plug formation.Be connected with registration wire in order to control the cord stroke between the connecting rod of backguy and double-point double-throw switch, registration wire can be that to restrict also can be that chain also has additional by the audio device of sticking relay switch, battery, the doorbell of holding concurrently, twoly touches the sound equipment display circuit that press button and light-emitting component constitute.Its light-emitting component is bulb or light emitting diode preferably.And be provided with at the light-emitting component place and show device, so that people or unmanned to be arranged in the display room.Display can be made of the housing of glazed window and the sideboard that is located in the housing.When adopting direct current generator, alternating current can be become direct current.Rectifier bridge that its alternating current circuit can be made of commutation diode and resistance or electric capacity are constituted.

Compared with the prior art the utility model owing to adopted sticking relay switch, starting relay and the double-point double-throw switch that is connected with backguy, has realized a purpose that the button that need press the sticking relay switch just can make curtain open automatically or cut out.Again owing to adopted sound equipment display circuit that constitutes by sticking relay switch, battery, two audio device that touches press button, light-emitting component and double doorbell and the display that is located at the light-emitting component place, make it not only have sound equipment and can replace doorbell again, the indoor people of having that also can accuse simultaneously or unmanned.Therefore, the utlity model has advantages such as reasonable in design, simple in structure, easy to use, effective, multi-functional.

By accompanying drawing, be described in detail three embodiment of the present utility model below.

Fig. 4 is the structural representation of display that is provided with the light-emitting component place of Fig. 3.

Fig. 5 is the circuit diagram of the 3rd embodiment of the present utility model.

Referring to Fig. 1, on fixed support 1, be provided with by the fastening galvanized wire hanging wire 4 of screw rod 2, motor 17, starting relay 25, the driven pulley of forming by large and small two sheaves 15, leading block 3, have double socket 12 by two ends, the base plate 14 that the centre has an articulated elements 10 and the connecting rod that has dual gate knife 13 9 that is connected with articulated elements 10 and hang over articulated elements 10 and connecting rod 9 on the double-point double-throw switch 8 that constituted of spring 11.Be installed with a sheave as driving wheel 19 on the axostylus axostyle of motor 17, its diameter ratio with driven pulley 15 is 1:3.On driven

wheel

19,15, be with the round spring driving-belt of making by steel wire 16, for prevent driving wheel 19 when rotated driving-belt 16 skid, driving-belt 16 is being enclosed within on the driven pulley 15 behind the unified circle on the driving wheel 19 again.Backguy 6 is root nylon wires, and it is enclosed within on the small grooved wheel of leading block 3 and driven pulley 15 sidepieces.Be connected with registration wire 7 on the connecting rod 9 of backguy 6 and double-point double-throw switch 8, registration wire 7 is brass chains.String has several plastics slip rings 5 on hanging wire 4.First slip ring 5 that is positioned at two hanging wire 4 middle parts is respectively by nylon wire 7 ' be connected with the backguy 6 that separates.

Fig. 2 is the circuit diagram of the electrically driven curtain of voiceless sound sound.It is made of sticking relay switch 21, motor 17 startup capacitors 25, double-point double-throw switch 8, attaching plug 20.Its sticking relay switch 21 is made of press button 29 and the lock-up relay that is made of base plate 30, guide pillar 28, electromagnet 27, armature 26, armature bracket 35, spring 34.

Fig. 3 is the circuit diagram of electrically driven curtain that has the sound equipment display circuit of the doorbell of holding concurrently.Its sound equipment display circuit is the audio device 18 that music integrated circuit and piezoelectric ceramic piece are formed, as the bulb and the battery 33(3 volt of light-emitting component 23), two electric shock button switch 22, sticking relay switch 21 constitute.Used sticking relay switch 21 is by the housing that has button and is located at electromagnet 27,

guide pillar

28,32 in the housing, and the armature 26, armature bracket 35, the spring 34 that have the guide pillar 31 of spring leaf and have an insulating trip 38 constitute.Two press buttones 22 that touch are by being garden shape in the end face that is located on the housing, being the button of annular phosphorus bronze sheet with its shape mutually suitable two the annular phosphor-copper contacts formations interior with being located at housing outward.

Referring to Fig. 4, it is provided in a side of the display 24 at bulb place, and this display 24 is made of the rectangular case 36 of glazed window and the transparent plastic sheet 37 that has an inserted link.At plate 37 subscripts " owner does not exist ", " woulding you please wait " printed words.

Referring to Fig. 5, motor 17 is 12 volts of direct current generators, and the rectifier bridge that constitutes of the commutation diode by 4 1A/400V and the resistance R of 1 22K/5W become 12 volts direct current with 220 volts of alternating currents.

Operation principle:

When pressing the sticking relay shift knob, armature contacts with guide pillar, at this moment, y road electric current flow through A, D to the b point to motor power supply, and form the loop with the X road and make the motor rotation.And the D point is in parallel with the C point, so electric current flows into and formation loop, X road at relay coil B, b ' c '.Because of there being electric current to produce magnetic field in the coil, and adhesive armature becomes the self-insurance state.And the double-pole of double-point double-throw switch is with moving by motor-driven backguy by registration wire.Contact with c ' at b ' and to become that b ' contacts with a ' or b ' contacts with a ' and become that the instant cut-off phenomenon appears in b ' road in b ' and the contacted process of c ', therefore the coil no current in the sticking relay switch then loss of excitation discharge armature, and the whole circuit outage causes the motor automatic stop.At this moment, the switch b of DPDT is if join, then start winding in capacitor and the motor is changed into by original parallel connection and connect or change parallel connection into by original series connection with c or with a, thereby realized the forward or reverse of motor, that is reached the purpose of curtain startup.

Be provided with the curtain of the sounder of the doorbell of holding concurrently, sounder pronounces thereupon when having additional guide pillar and having the sticking relay shift knob of guide pillar of phosphor-copper spring leaf pressing.Two when touching the button of press button (being doorbell switch) when pressing, acoustics circuit, illuminating circuit are connected simultaneously, and this moment, sound equipment, lamp were bright.Owner with can not represent (as shown in Figure 4) by the The attracted numbers on the display.
