When the winder is actually assembled, please refer to fig. 1 to 5, the winder a is assembled first and then can be embedded into the curtain rail B, and the winder a is assembled by correspondingly assembling the winding shaft 1 into the winding shaft seat 2, so that the first shaft part 11 and the second shaft part 12 at the two ends of the winding shaft 1 are respectively embedded into the first embedded shaft part 21 and the second embedded shaft part 22 of the winding shaft seat 2; then, correspondingly pivoting the movable locking piece 3 at the pivot 231 of the neck 23 of the first shaft-embedding part 21, so that the pivot lug 31 of the movable locking piece 3 is correspondingly pivoted with the pivot 231, and the movable locking piece 3 is vertically placed downwards, and the concave part 312 of the pivot lug 31 is located at the top end position; then, the elastic unit 4 is correspondingly inserted from above the neck 23, the elastic piece 42 is correspondingly inserted into the locking groove 211 of the end surface of the first shaft-inserting part 21, and the protrusion 43 at the bottom edge of the elastic unit 4 is correspondingly inserted into the recess 312 of the pivot lug 31, so that the elastic unit 4 and the movable locking piece 3 are assembled and positioned on the reel seat 2, and the assembly of the reel A is completed.

However, in order to provide a more stable positioning and locking effect between the bobbin 1 and the elastic unit 4, a protrusion 411 is further provided in the inner ring portion 41 of the elastic unit 4, the neck 23 of the first shaft portion 21 is provided with a first groove 212 corresponding to the protrusion 411, and a second groove 111 is provided on the shaft wall of the first shaft portion 11 corresponding to the protrusion 411, so that the protrusion 411 can be inserted into the first groove 212 of the first shaft portion 21 and the second groove 111 of the first shaft portion 11 correspondingly to achieve the positioning effect of locking the first shaft portion 11 at a position of 90 degrees, meanwhile, after the winding reel 1 is fixed at the right 90 degrees of the same angle, the transmission rod C is conveniently arranged at the center of the winding reel 1 in a penetrating way, and the phenomenon that the winding reel 1 is locked and does not rotate when a plurality of simple and rapid corresponding winding reels A are correspondingly assembled at proper positions of the curtain track B is facilitated.

In order to provide a positioning and locking effect between the spool 1 and the elastic unit 4 for faster positioning and assembly, another embodiment is provided, that is, a buckle handle 32 for pulling the movable locking piece 3 to rotate is formed at an end of the movable locking piece 3 opposite to the pivot lug 31, a through slot hole 321 (as shown in fig. 10) is formed on the buckle handle 32, an accommodating chamber 112 is formed at the first shaft 11 of the spool 1, a sliding seat 13 capable of clamping a rope is embedded in the accommodating chamber 112, and the sliding seat 13 can be correspondingly inserted through the through slot hole 321 for faster positioning. To explain the practical operation, after the winding reel 1 is placed in the reel seat 2, the front section of the sliding seat 13 is inserted into the accommodating chamber 112 of the first shaft portion 11, and the rear section is correspondingly inserted into the through-slot 321 of the movable locking piece 3, so that the winding reel 1 can be positioned at a positive 90-degree position, and meanwhile, the first shaft portion 11 of the winding reel 1 is locked. Therefore, in the process of assembling the parts related to the pivot-setting winder a, the through slot 321 of the movable locking piece 3 is correspondingly clamped with one end of the sliding seat 13, so that the winding reel 1 can be positioned and locked firstly, then the elastic unit 4 is assembled to be embedded into the neck 23 in the upper part, and simultaneously the convex strip 411 of the elastic unit 4 is directly embedded into the first groove 212 of the neck 23 in the state that the winding reel 1 is not required to be aligned with again, and is clamped in the second groove 111 of the first shaft part 11 in a pivot manner to lock the winding reel 1 in the above-mentioned double repositioning manner, so that the elastic unit 4 and the movable locking piece 3 are assembled and positioned on the winding reel seat 2, and the assembly of the winder a is completed quickly.

Referring to fig. 6 to 9, after the assembly of the cord reel a, the cord reel a is inserted into the curtain rail B, and the elastic unit 4 of the cord reel a is inserted into the neck 23 at the same height as the first shaft-inserting portion 21, so that the cord reel a can be smoothly inserted into the curtain rail B; then, the position of the reel A is set according to the curtain. When the winder a is positioned, the movable locking piece 3 is rotated upwards to make the pivot lug 31 rotate around the pivot piece 231, at this time, the angle of the pivot lug 31 is changed to make the concave part 312 separate from the convex part 43 at the bottom edge of the elastic unit 4, and the concave part is rotated to convert the pushing ring part 311 to push against the convex part 43, so as to push the elastic unit 4 upwards, but because the elastic piece 42 is embedded in the clamping groove 211 and has elastic force, when the elastic unit 4 moves upwards, the elastic piece 42 deforms and is also embedded in the clamping groove 211, so as to keep the elastic unit 4 assembled and positioned at the neck 23; when the elastic unit 4 moves upwards, the top edge of the elastic unit 4 is correspondingly pressed against the inner wall of the curtain rail B, so that the winder A is assembled and positioned on the curtain rail B.

When the elastic unit 4 moves upward, the protrusion 411 of the inner ring portion 41 is disengaged from the second groove 111 of the first shaft portion 11, but is not disengaged from the first groove 212 of the first shaft portion 21, and after the first shaft portion 11 of the winding shaft 1 is disengaged from the limit, the user can pull the rope to control the curtain cloth to ascend and descend.

As shown in fig. 6, a groove 213 for positioning is formed at the top end of the end surface of the first shaft-embedding portion 21 of the shaft seat 2 corresponding to the curtain rail B, and a convex block 214 for abutting against the inner wall of the curtain rail B is formed at the bottom end; in addition, when the movable locking piece 3 is actuated, the pivot lug 31 will abut against the inner end surface of the first shaft-embedding portion 21, and therefore, an elastic notch 215 is further formed on the end surface of the first shaft-embedding portion 21 corresponding to the pivot lug 31, and the elastic notch 215 is used for relieving the abutting pressure of the pivot lug 31.

The above description is only an exemplary embodiment of the present invention, and is not intended to limit the scope of the present invention. Any equivalent changes and modifications that can be made by one skilled in the art without departing from the spirit and principles of the invention should fall within the protection scope of the invention.
