Description

The electrically driven curtain frame

The utility model is a kind of improved electrically driven curtain frame.

At present, it is steel wire or cordage that general electrically driven curtain frame hangs carrier, and there is " light leak " phenomenon in sagging the open and flat of curtain face that influence when cord hangs, the undesirable and curtain rod arm installation trouble of shading, and skidding appears in cord when opening and closing.

The purpose of this utility model provides a kind of easy for installation, opens and closes steadily the curtain rod arm that the curtain face is open and flat.

This electrically driven curtain frame of the present utility model is shown in Fig. 1～8, by the curtain frame (1) that has curtain groove (16), device is at the electrical equipment box (10) at curtain frame (1) two ends, the driving (3) that can in curtain frame (1), reciprocatingly slide, pulley (2) support (8), device is gone up the conducting copper belt (4) and the hook (14) of circuit between connecting circuit box (10) and the driving (3) at curtain frame (1), stand (12), switch enclosure (11) is formed, its improvements are, above-mentioned curtain groove (16) is two the curtain grooves arranged side by side in front and back, driving (3) and several pulleys (2) that a pair of reverse walking is respectively arranged in two curtain grooves, each device has three conducting copper belt (4) in the two curtain grooves, connection circuit negative pole in the middle of it, the two connection circuit positive poles in next door have the metal contact (6) of mating and have excellent electric contact with conducting copper belt (4) in the driving (3).The electrical equipment box (10) at curtain frame (1) two ends is the 12V direct current with the 220V alternating current transformation rectification of input, its three output lines, and one is negative pole, two is anodal, through three metal contact (6) overlap joint of three conducting copper belt (4) with driving (3) top.When the button of pressing on the switch enclosure (11), circuit is connected, and starts driving (3) and oppositely go, drives cord (9) separately or when gathering cord and gathering, and bumps effect because of two friendships of commutation contact (7) of driving a vehicle (3), and driving a vehicle stops displacement, finishes the switching motion of cord.Here, because hanging the hook (14) of cord directly is fixed on driving (3) and the pulley (2), cord is whole thereupon to be moved, no sagging is with the crawler belt (5) that also can walk with curtain frame (1) coupling on driving (3) wheel in addition on the curtain frame, because crawler belt (5) is adopted in driving (3) walking, so the adhesive force that acts on the groove can not skid greatly, make driving open and close steadily, cord launches fully to have reached ideal effect.In addition, described curtain frame (1) is designed to multistage curtain groove capable of being combined, have slotted eye (15) on every section curtain groove, be connected firmly with screw (13) by the circular hole (18) on this hole and the support (8), so whole width that the user can regulate the fixed screen frame arbitrarily, support (8) is inserted in the slotted eye (17) of fixing stand (12) on the wall, very convenient.

Below in conjunction with accompanying drawing curtain rod arm of the present utility model is elaborated:

Fig. 1 is the structural representation of a specific embodiment of electrically driven curtain frame.

Fig. 2 is the cutaway view of electrically driven curtain frame shown in Figure 1;

Fig. 3 is middle curtain groove structural representation side by side;

Fig. 4 is a left side curtain groove structural representation side by side;

Fig. 5 is a right side curtain groove arranged side by side structural representation;

Fig. 6 is the stand structural representation;

Fig. 7 is the supporting structure schematic diagram;

Fig. 8 is the conducting copper belt structural representation.

In accompanying drawing 1～8 illustrated embodiment, support (8) is the carrier of curtain frame (1), and plastics are made, the cross section is the l type and has circular hole (18), curtain frame (1) is to be combined by the multistage curtain groove arranged side by side (16) that sheet metal is made, side by side the curtain groove shown in Fig. 2～5, long 500mm, has slotted eye (15), stage casing curtain groove arranged side by side and the intercommunication of left and right section curtain groove arranged side by side, collection transformer in curtain frame (1) the built-in electrical apparatus box (10), electrical equipment box (10), rectifier, electrical equipment such as relay are in one.Driving (3) and pulley (2) are walked in groove and are not come off.Driving (3) interior current collection machine reversing switch and drive are in one.Scalable the resetting of three contacts (6) of driving (3) top, scalable the resetting of commutation contact (7) of driving (3) left and right side.To bump be cord when overlapping or cord when gathering when commutation contact (7) is handed over mutually, press reversing button, even the anti-former direction walking cord of driving a vehicle separates.It is fixing on the wall with steel nail that stand (12) is pressed the precalculated position of support (8).Conducting copper belt (4) is pressed and is embedded in the plastic tape (19), as shown in Figure 8.The switching motion of one deck cord (9) is finished in a pair of driving (3) in the groove.Two-layer cord can open and close separately, also can open and close simultaneously.Switch enclosure (11) is established two groups of buttons, one group of control one deck cord, and in one group of button, forward, they are respectively inching button and automatic button each two of reversing buttons.The forward button is the breakdown button, and reversing button then is a close push button.Driving (3) and pulley (2) are that plastics are made, and crawler belt (5) and drive nylon are made.Electrically driven curtain frame of the present utility model uses through trial-manufacture of sample, proves that it has keying freely, and cord is open and flat, satisfactory for result, and good looking appearance uses and pack all characteristics very easily.

Claims (1)

1, a kind of improved electrically driven curtain frame, it is by the curtain frame (1) that has curtain groove (16), device is at the electrical equipment box (10) at curtain frame (1) two ends, the driving (3) that can in curtain frame (1), reciprocatingly slide, pulley (2), support (8), conducting copper belt (4) and the hook (14) of device on curtain frame (1), stand (12), switch enclosure (11) and stand (12) are formed, it is characterized in that, above-mentioned curtain groove (16) is a multistage curtain groove arranged side by side, have slotted eye (15) on every section curtain groove arranged side by side (16) and the curtain frame (1) and be connected support (8) with circular hole (18) on the support (8) by screw (13) by this slotted eye (15), described curtain, also has conducting copper belt (4) on the frame (1), have the metal contact (6) of mating and have excellent electric contact with conducting copper belt (4) in the driving (3), be with the crawler belt (5) that also can on the curtain frame, walk with curtain frame (1) coupling on above-mentioned driving (3) wheel.
