[0002] During the use of the curtain, in order to ensure that the curtain can automatically slide in a serpentine manner, it is often necessary to install a pulley on the electric serpentine track in advance.

[0003] At present, the pulley on the electric serpentine track is mainly composed of a long slider and a slip ring installed at the bottom of the slider. Although the pulley of this structure can realize the convenient sliding of the curtain when in use, on the one hand, due to the fixed overall structure of the curtain pulley of this structure, the pulley cannot slide flexibly according to the curvature of the track when in use, and is prone to getting stuck during the sliding process, which is not convenient for efficient opening and closing adjustment of the curtain. On the other hand, due to the fixed distance between the connecting ropes of the two pulleys of the pulley of the above structure when in use, the pulley cannot adjust the folding length of the curtain after installation according to the size of the curtain when in use, resulting in low installation efficiency of the curtain.

[0020] (III) Beneficial effects

[0021] Compared with the prior art, the utility model has the following beneficial effects:

[0022] In order to solve the problem that the pulley on the current electric serpentine track is mainly composed of a long slider and a slip ring installed at the bottom of the slider, although the pulley of this structure can realize the convenient sliding of the curtain when in use, on the one hand, due to the fixed overall structure of the curtain pulley of this structure, the pulley cannot slide flexibly according to the curvature of the track when in use, and it is easy to get stuck during the sliding process, which is not convenient for efficient opening and closing adjustment of the curtain. On the other hand, due to the fixed distance between the connecting ropes of the two pulleys of the pulley of the above structure when in use, the pulley cannot be adjusted according to the size of the curtain when in use. The folding length of the entire curtain after installation leads to the problem of low installation efficiency of the curtain. On the one hand, the utility model allows the front and rear parts of the curtain pulley to rotate relatively when in use through the design of the rotating plate 1, the rotating plate 2 and the rotating shaft. This design prevents the pulley from getting stuck when sliding on the straight track and the curved track, which is convenient for efficient opening and closing adjustment of the curtain. On the other hand, the limiting screw sleeve and the limiting column are used to adjust the length of the connecting rope between two adjacent pulleys, which is convenient for flexible adjustment of the folding length of the curtain after installation according to the size of the curtain, thereby improving the installation efficiency of the curtain.

A rotating shaft 8 is installed between the rotating plate 15 and the rotating plate 26. Under the action of the rotating shaft 8, the rotating plate 15 can be conveniently rotated and adjusted relative to the rotating plate 26. The rotating plate 26 is connected to a slide 27 on the side facing away from the rotating shaft 8. A hanging ring 4 is installed at the bottom end of the slide 2 and the bottom end of the slide 27. A limiting column 11 is also installed on one side of the hanging ring 4 on the slide 2, and a connecting rope 3 runs through the limiting column 11. The connecting rope 3 is mainly used to be connected to the hook on the curtain. A limiting screw sleeve 10 is installed on the outside of the limiting column 11 at the bottom end of the slide 2. The limiting screw sleeve 10 will press the connecting rope 3 when it moves downward after rotation, thereby realizing the limiting of the connecting rope 3 after the length adjustment.

The belt fixing seat 1 and the belt fixing buckle 9 are mainly used to connect the pulley with the toothed belt on the electric track. The belt fixing seat 1 is plugged into the slide 1 2 and the slide 2 7, and the belt fixing buckle 9 is plugged into the belt fixing seat 1, so that the slide 1 2 and the slide 2 7 can move synchronously with the belt fixing seat 1, so as to adjust the opening and closing of the curtain.

[0031] like Figure 1-Figure 3 As shown, in the present embodiment, the rotating plate 1 5 is formed on the slide 1 2, the rotating plate 2 6 is formed on the slide 2 7, and the connecting parts of the rotating plate 1 5 and the rotating plate 2 6 are staggered to avoid mutual interference between the rotating plate 1 5 and the rotating plate 2 6 during relative rotation. The rotating shaft 8 and the rotating plate 1 5 and the rotating plate 2 6 are all rotatably connected with the rotating shaft 8, and the rotating shaft 8 passes through the connecting part of the rotating plate 1 5 and the rotating plate 2 6. The limiting column 11 is welded to the slide 1 2, and the part of the limiting column 11 connected with the connecting rope 3 is a hollow structure, which can ensure that the connecting rope 3 can be easily passed through the limiting column 11. The limiting screw sleeve 10 is screwed to the slide 2, and the limiting column 11 passes through the limiting screw sleeve 10.

[0032] The specific implementation process of this embodiment is as follows: when in use, the curtain pulley is first installed on the pre-set electric track in the room and the connecting rope 3 on the pulley is connected to the hook on the curtain, and then the pulley can be put into use. During use, under the action of the rotating plate 1 5, the rotating plate 2 6 and the rotating shaft 8, the front and rear parts of the curtain pulley can rotate relatively when in use. This design ensures that the pulley will not get stuck when sliding on the straight track and the curved track, which is convenient for efficient opening and closing adjustment of the curtain. At the same time, the limiting screw sleeve 10 and the limiting column 11 are used to adjust the length of the connecting rope 3 between two adjacent pulleys, which is convenient for flexibly adjusting the folding length of the curtain after installation according to the size of the curtain, so that the installation efficiency of the curtain is improved.
