Abstract

The utility model discloses an electric moving window curtain, which changes a 220V commercial power supply into a direct current power supply to connect a miniature electric motor, which makes a curtain mechanism move. The whole mechanism is installed in a housing and also provided with a limiting reversing switch in order to realize the automatic stop after the slide block is in position and make the commutation of the miniature electric motor. The electric moving window curtain of the utility model has the advantages of simple structure, convenient operation.

Description

Electric moving window curtain

The utility model relates to the electric curtain mechanism that uses in a kind of daily life.

At present, what people used always is the hand curtain mechanism, though it is simple in structure, cost is low, and inconvenient operation is normal bad because of firmly grasping when pulling lead owing to people, makes a mess of curtain mechanism easily; On the market a kind of distance type electric curtain mechanism has appearred recently, this mechanism is by transformer, motor, decelerator, driving wheel, driven pulley, left and right slide block, slide rail, the belt line, limit switch, straighforward operation dish, remote control receiving key form, and opening or closing by the straighforward operation dish of curtain " opened " or " pass " two buttons are realized.Though this remote control electric curtain is easy to operate, the cost height be difficult for to be popularized, and all parts all are exposed installations, so very not attractive in appearance.

The utility model is to provide a kind of cost lower, easy to operate, the enclosed motor curtain mechanism of good looking appearance.

The purpose of this utility model is achieved like this, with transformer, and motor; decelerator; driving wheel, driven pulley, left and right slide block; pulley; slide rail, the belt line reasonably is fixedly installed in the shell by connector, and loads onto spacing reversing switch; with realize left and right slide block put in place the back (be curtain " open " or " passs " afterwards) autostop, and make motor commutation.Above-mentioned transformer connects electricity after by starting switch, and 220 volts of civil powers are become direct current about 6 volts.

Described left and right slide block all with the belt line on suitable point be fixedly connected, and two pulleys are housed separately on each slide block, so that the slide block easy motion.

Two spacing joints are arranged on the described belt line, so that slide block is when putting in place, spacing joint drives spacing reversing switch action, even down circuitry is shut down, and the both positive and negative polarity of motor is oppositely connected, then motor commutation.

The utlity model has aesthetic in appearance, simple in structure, easy to operate, dependable performance, the advantage that cost is low.Owing in the utility model spacing reversing switch is housed, make the "on" and "off" of curtain only need a starting switch, will never maloperation.

Embodiment is described in further detail the present technique utility model below in conjunction with (accompanying drawing):

Accompanying drawing is a main cutaway view of the present utility model.

With reference to accompanying drawing, motor 18(selects wzy-131 for use) with decelerator 1(speed ratio be 1:16) all be arranged on the left support plate 19, and be 1:1.5 by a pair of garden dish gear 20,21(speed ratio) driving coupling; The input of decelerator 1 is loaded onto driving wheel 2.Transformer 13, circuit board 15 and driven pulley 11 are installed on the right support plate 12, and the circuit board 15 here connects power switch 14, and the spacing reversing switch 8 of KW4-UZ is housed, and the stroke plate washer 9 of spacing reversing switch 8 has through hole to pass by belt line 3.

With left and right two support plates 19 and 12 after above-mentioned the assembling, be fixed in and arranged on left and right sides in the shell 5 with rivet, form symmetry and split.

On left and right two

slide blocks

17 and 16 two pulleys 6 are housed separately,, and fixedly connected with belt line 3 by screw so that slide block movement steadily, freely.

Upper and lower two of slide rail 4 minutes, and be connected as a single entity with three connecting plates 7 moves therein and does not break away from slide rail to guarantee pulley 6 on the slide block.The last piece of slide rail 4 is " ┓ " type and the riveted joint of shell 5 tops.

The nylon wire of belt line 3 usefulness φ 1.5 is made closed-loop, by driven pulley 11, forms closed circuit transmission behind round turn on the driving wheel 2.Two spacing joints 10 are arranged on the belt line 3, make left and

right slide block

17,16, the back that puts in place (being that curtain " is opened " or " passs " back) thus drive the stroke plate washer 9 action outage shutdown of spacing reversing switch 8 and motor 18 oppositely connected.

Claims

A kind of electric curtain mechanism, by transformer 13, motor 18; decelerator 1, driving wheel 2, driven pulley 11; left and right sides slide block 17,16, pulley 6, slide rail 4; belt line 3; start exploitation 14 and form, it is characterized in that: above-mentioned parts all is fixedly installed in the shell 5 by support plate, connector except that starting switch; and spacing reversing switch 8 is housed, to realize put in place back self-stopping and make motor commutation of slide block.
