Abstract

The utility model relates to a motor-driven device for opening and closing curtain. The utility model is characterized in that a curtain cover and a guide rail are formed into an ornament which has beautiful appearance; an alternating current machine whose voltage is 220V is adopted for driving; a function of automatic opening and closing for curtains is formed by mechanical transmission; automatic closing with travel spacing is adopted; a controller is separated with a power device; one controller can load a plurality of power devices of a same circuit and simultaneously open and close a curtain by utilizing operation in different distances. The utility model has the advantages of rapid opening and closing for curtains, time saving, labor saving, less power consumption, capability of long-distance operation; the utility model is suitable for places where curtains need opening and closing, such as offices, communities, guesthouses, restaurants, enterprises and institutions and families.

Description

Motor-driven device for opening and closing curtain

The utility model belongs to a kind of electric device for draw-back curtain that the household goods door and window is decorated.

Existing curtain mostly is the guide tracked draw-back curtain that pulls, operation inconvenience, waste time and energy, 91207572.4 number patented technology has solved the problems referred to above, but because it adopts the 9-24V direct current generator to drive, can not directly use alternating current, must be through step-down rectifier, thereby cost is higher, and structure is also comparatively complicated, also must pin gauge tap during use and could realize the automatic shutter curtain.

The utility model is to carry out simplified structure on the basis of No. 91207572.4 patented technologies, reduce cost and design a kind ofly have curtain and open and close quick, easy to operate electric device for draw-back curtain.

The utility model is realized with following measure, electric device for draw-back curtain, comprise by curtain cover, guide rail, the slip crane, sliding hook, transmission rope, power set, compositions such as stroke position-sensing switch device and control system, it is characterized in that power set are installed in the curtain cover, one end of cover is equipped with small-sized alternating current generator M and the driving wheel 2 that is connected with the motor M axle center, the bearing 3 of motor M is installed, in the upper end of bearing 3 lead limit switch K3 is installed, constitute initiatively transmission device, the bearing 3 of the other end of curtain cover is equipped with follower 4, as passive transmission device, link with transmission rope 5 between driving wheel 2 and the follower 4, the two-way back and forth fixed point respectively of transmission rope 5 is pressed the rightabout locating engagement with two slip crane 7-1 and 7-2 on the guide rail 6, bump briquetting 8 is housed on the slip crane 7-1 top of the guide rail 6 of active transmission device one end, be used for impact stroke limit switch K3 or K4, bearing 3 and lead limit switch K4 are installed in the middle of guide rail 6, constitute a motorized motions, mechanically operated automatic shutter window shade arrangement, other has a control system of separating with power set, be to insert junction block A and B by the 220V AC power cord, the B line meets power switch K1 after meeting fuse protection device RD, through indicator lamp V, be connected with motor M behind the lead limit switch K3 of power set to junction block C behind the DPDT gauge tap K2, constitute a normal polarity circuit, the motor M power line is connected with a contact of K2 after inserting the E joint; The zero line of motor M is connected with the C contact of K2 after connecing lower contact behind the K4, constitutes the reversed polarity circuit.

Make description of drawings below:

Fig. 1 is the electric device for draw-back curtain outline drawing.

Fig. 2 is the electric transmission machanism structure chart.

Fig. 3 is the control system line map.

Describe this practicality below in conjunction with accompanying drawing with embodiment, novel effect and advantage: the 220V AC power inserts junction block A, B, circuit, and C, D group is the normal polarity circuit, and K is that moving disconnection of forward circuit closed; E, F group is the reversed polarity circuit, K4 is that moving disconnection of negater circuit closed, power supply B line is through fuse protection device RD, through power switch K1, connect the f contact that is connected the direct K2 of A line behind the indicator lamp V with the e contact of double-point double-throw switch K2, tap is connected with zero line between indicator lamp V and the power switch K1, constitutes the normal polarity circuit; The power line of motor M is connected with a contact of K2 after inserting E line seat, the zero line of motor M is connected with the C contact of K2 after inserting wiring F behind the K4, constitute the reversed polarity circuit, when needing work, power switch K1 is connected, indicator lamp V is shinny, and indication circuit is logical, can carry out work, if will draw the curtain apart, earlier gauge tap K2 is dialled to b, the d contact, forward circuit energising this moment, motor M running, drive coaxial driving wheel work forward running, driving wheel is made positive movement by the slip crane 7 on transmission rope 5 sliding guides 6 under the cooperation of follower 4, the casement that hangs on slip crane 7 and the sliding hook 10 is drawn the curtain apart with the positive movement of slip crane 7, bump briquetting 8-1 to the crane 7 that slides presses lead limit switch K3, cut off the motor M operating circuit, motor M promptly shuts down, and curtain is also opened simultaneously; If need close curtain, then the power supply cutter of gauge tap K2 is dialled to a, C contact, oppositely circuit energising, the motor M antiport, transmission device is done counter motion equally, casement is also closed with reverse drive, the passive power machine operating circuit of lead limit switch K4 in the middle of slip crane 7-1 arrives guide rail 6, motor M quits work, and curtain is also closed simultaneously, the advantage of this electric device for draw-back curtain (1) power is big, curtain opens and closes quick, and is time saving and energy saving, little power consumption, simple in structure, cost is low; (2) power set separate with control system, can control in the different distance operation as required, but and the power set that the same indoor a plurality of curtain of control device load open and close, convenient and practical; (3) can shut down automatically after curtain opens and closes, it is applicable to each office, group, hotel, dining room, the place of all palpus draw-back curtains such as the building of each enterprises and institutions, hall shop institute and home dwelling.
