Each of the heads 70 is sleeved at one end of the rail 30 and screwed by a screwing member 701. Referring to the second and fourth figures, in the assembled structure of the present invention, at the first end of the electric reel 40, for example, the right end of the fourth figure, the shaft post 75 of the right head 70 is threaded into the head 44 of the reel 40. The socket 441 is configured to support one end of the reel, and the second screwing member 401 is screwed from the first assembly hole 77 to the locking hole 442 of the head 44 to fix the end of the reel; the reel wire 48 is from the right end 70. The upper wire outlet hole 791 passes through the rail 30. The second end of the reel 40, as shown in the left end of the fourth figure, is passed through the shaft hole 76 of the shaft post 75 of the left head 70 with its mandrel 47 so that the other end of the reel is pivotally connected to the head 70.

The eighth figure shows that the electric curtain cooperates with one of the curtain fabrics 26, and the fastening tape provided on the top end of the fabric 26 is fastened to the fastening tape 32 on the first side of the rail 30, and the winding rope 58 is re-attached. The bottom end is connected to the bottom end of the fabric to form an electric cloth curtain, and the power source is turned on to rotate the electric reel 40, and the rope drum 55 of the rope reel mechanism 50 can be rotated together, and the rope drum will be wound. 58 is wound around the The barrel 56 raises the fabric 26; conversely, when the electric reel 40 and the reel 55 release the reel 58, the fabric 26 is lowered, and thus the lifting and lowering of the curtain can be controlled.

The closure 70 of the present invention can be used with electric reels produced in different forms or by different manufacturers. Referring to the ninth drawing, another electric reel 40' and a head 70 are shown. The end surface of the head 44 of the reel 40' is provided with a socket 441 and four locking holes 442'. When assembled, the reel 40' is placed in the rail and the connection relationship with the reel member is as shown above, and will not be described. The socket 441 of the head 44 of the reel 40' is interposed with the shaft post 75 of the head 70; the four screwing member 401 is screwed to the locking hole of the reel by the second assembly hole 78 of the reel 442', by which the first end of the reel is fixed; at the same time, the wire 48 of the reel is threaded out from the wire exit hole 792 under the head 70. Thus, the closure of the present invention can be integrally adapted to different forms of electric reel.

The electric curtain 20 of the present invention can also be assembled into a louver type curtain. Referring to the tenth to twelfth drawings, each rope reeling mechanism 50 is connected with a rope 80, and the top end of the rope is wound in the ladder rope groove 57 of the rope drum 55, as in the first.

Inside, the color or pattern of the trim 38 is matched with the blade to create a sense of unity.

The thirteenth and fourteenth drawings are another use example in which the present invention is assembled into a venetian blind. The other components are the same as those of the venetian blinds except for the ladder cord 90, and are not described herein.

The ladder rope 90 is a belt-type ladder rope having a rope segment 92 and a belt-shaped wire segment 94 connected to the two ends of the rope segment 92; the rope segment 92 is wound around the ladder rope groove 57 of the rope drum 55, The two ends are respectively connected to the top end of the two line segments 94 by a connecting member 921; a plurality of horizontal ropes 95 are equally spaced between the two line segments 94; the ladder rope 90 further comprises: two decorative strips 96, each decorated The bottom end of the belt 96 is attached to the top end of the line segment 94, and the top end is sewn into a sleeve portion 97. In practice, the sash 96 and the line segment 94 are the same tape. A plurality of blades 85 are disposed between the two line segments 94 of the ladder rope 90 and are respectively disposed on a horizontal rope 95. The winding rope 58 is disposed through the through holes 86 of the blade 85.

The use case is characterized in that the wearing portion 97 of the sash 96 of the ladder cord 90 is fastened from the free end 67 of the cantilever 66 of the clamping piece 60 to the cantilever 66, so that the two sashes 96 are hooked on the track. 30 and the blade cover the two ends of the rope segment 92, and the sash 96 is integral with the wire segment 94, so that the curtain has a more beautiful appearance.

It can be understood from the above description that the electric curtain provided by the invention has the following effects:

1. The present invention replaces the bracket and end cover of the conventional electric curtain with a head to simplify the structure and components of the electric curtain, and makes the assembly operation of the electric curtain more convenient and quick. Although the two ends of the electric reel are different in construction, the construction of the head is versatile and can be connected to each end of the electric reel to support the electric reel.

Second, the head is equipped with multi-assembled holes and wire outlets. The electric reel with different structures or forms is integrated. The curtain manufacturer does not need to make different brackets, which can reduce the manufacturing cost and reduce the material management.

Third, the use of the invention can make the electric reel wire hidden in the track, the re-opening head is worn out, the electric wire is not exposed on the top surface or the bottom surface of the track, so that the overall structure is beautiful; and the head of the invention also has different positions The wires are out of the hole and the power supply line is threaded out from different positions.

4. In addition, in the conventional structure shown in the first figure, a plurality of rope holes 17 are required to be punched out on the bottom surface of the track for the cable to pass through, and the position of the rope drum 15 is limited to the rope hole 17, which cannot be changed at will; In contrast, in the preferred embodiment of the present invention, the bottom surface of the track is vacant, and the rope reeling mechanism, the rope and the ladder rope can be installed at any position of the track, and the assembly convenience is convenient, and the rope reel mechanism can be added or removed at any time. The number of installations.

In summary, the present invention provides an innovative structure for electric curtains, and has many practical effects, and is applied according to law.
