[0044] Reference Figures 1 to 11 , a curtain roller, comprising:

[0045] The reel body 1 is used to connect with the curtain 2, and the reel body 1 can be rotated on the surface of the curtain 2 to a reeling position or an unfolding position. When the reel body 1 is rotated to the reeling position, the reel body 1 reels the curtain 2; when the reel body 1 is rotated to the unfolding position, the reel body 1 unfolds the curtain 2;

[0046] The stop part 3 is connected to the roller body 1, and a stop space 11 is formed between the stop part 3 and the roller body 1. When the roller body 1 rotates to the reeling position to reel in the curtain 2, and the curtain 2 is located in the stop space 11, the roller body 1 cannot rotate on the surface of the curtain 2 to stop the roller body 1 at the reeling position.

[0047] Through the above structure, since it includes a reel body 1, the reel body 1 is used to connect with the curtain 2, and the reel body 1 can be rotated on the surface of the curtain 2 to a reeling position or an unfolding position. When the reel body 1 is rotated to the reeling position, the reel body 1 reels the curtain 2; when the reel body 1 is rotated to the unfolding position, the reel body 1 unfolds the curtain 2; the stopper 3, the stopper 3 is connected to the reel body 1, and a stopper space 11 is formed between the stopper 3 and the reel body 1. When the reel body 1 is rotated to the reeling position, the reel body 1 reels the curtain 2; when the reel body 1 is rotated to the unfolding position, the reel body 1 unfolds the curtain 2; the stopper 3 is connected to the reel body 1, and a stopper space 11 is formed between the stopper 3 and the reel body 1. When the curtain 2 is rolled up and the curtain 2 is located in the stop space 11, the reel body 1 cannot rotate on the surface of the curtain 2, so that the reel body 1 is stopped at the reeling position, so that the user can roll up the curtain 2 by rotating the reel body 1 on the surface of the curtain 2 to the reeling position. After the reeling is completed, the curtain 2 can be placed in the stop space 11 formed between the stop part 3 and the reel body 1, so that the reel body 1 cannot rotate on the surface of the curtain 2, so that the reel body 1 is stopped and fixed at the reeling position to prevent the curtain 2 from slipping and unfolding. In addition, when the user needs to unfold the curtain 2, the curtain 2 can be separated from the stop space 11, so that the curtain 2 can be rotated on the surface of the curtain 2 to the unfolding position to unfold the curtain 2. Specifically, the reel body is connected to the bottom of the curtain, so that the reel body can roll up the curtain from the bottom to the top, and the reeling position of the curtain can be adjusted according to the angle of sunlight, so that the window can be transparent while blocking direct light to avoid direct light, so as to improve the user experience.

[0048] When the roller body 1 rotates to the reeling position on the inner surface 21 of the curtain 2 to reel in the curtain 2, and the curtain 2 is located in the stopping space 11, the stopping portion 3 abuts against the outer surface 22 of the curtain 2, so that the roller body 1 cannot rotate to the unfolding position on the inner surface 21 of the curtain 2, thereby stopping the roller body 1 at the reeling position.

Specifically, the stopper portion 3 has a first magnetic attraction component 31, the reel body 1 has a first magnetic attraction matching component 12, and the first magnetic attraction component 31 is magnetically connected to the first magnetic attraction matching component 12. Through the above structure, when the user needs to rotate the reel body 1 along the surface of the curtain 2 to the reeling position or the unfolding position, the stopper portion 3 can be detached from the reel body 1, so that the reel body 1 can be rotated along the surface of the curtain 2 to the reeling position or the unfolding position. When the user rotates the reel body 1 to the reeling position to reel a part of the curtain 2, the stopper portion 3 can be connected to the reel body 1 to place the curtain 2 in the stopper space 11 formed between the reel body 1 and the stopper portion 3, so that the reel body 1 cannot rotate on the surface of the curtain 2, so as to stop and fix the reel body 1 at the reeling position to prevent the curtain 2 from slipping and unfolding. Furthermore, since the stopper part 3 is magnetically connected to the reel body 1 , it is convenient for the user to install and remove the stopper part 3 .

Specifically, the stopper part 3 has a first magnetic attraction part 31, the reel body 1 has a first magnetic attraction fitting part 12, and the first magnetic attraction part 31 is magnetically connected to the first magnetic attraction fitting part 12; the first magnetic attraction fitting part 12 is arranged in the first mounting hole 14, and the first magnetic attraction part 31 is arranged in the first mounting shaft 34. Among them, the first mounting shaft 34 has a fourth mounting hole 341, and the first magnetic attraction part 31 is arranged in the fourth mounting hole 341. Through the above structure, the design is reasonable, and the setting of the stopper part 3 is effectively realized, which can facilitate the user to install and disassemble the stopper part 3, so that the user can fix the reel body 1 in the winding position.

[0052] In this embodiment, the reel body 1 has a first end 15 and a second end 16 opposite to the first end 15, and the number of the stopper parts 3 is two, and the two stopper parts 3 are respectively connected to the first end 15 and the second end 16. Through the above structure, the two stopper parts 3 can stop and fix the two ends of the reel body 1, so as to fix the reel body 1 at the reeling position to reel the curtain 2, and can effectively prevent the reel body 1 from rotating to the unfolding position to unfold the curtain 2.

One end of the first connecting rod 17 has a first connecting portion 171, the first connecting portion 171 has a second mounting hole 1711, the second connecting rod 18 is inserted into the first connecting rod 17 through the second mounting hole 1711, and the second connecting rod 18 can slide and retract in the first connecting rod 17. The reel body 1 further includes a third connecting rod 19. The other end of the first connecting rod 17 has a second connecting portion 191, the second connecting portion 191 has a third mounting hole 1911, the third connecting rod 19 is inserted into the first connecting rod 17 through the third mounting hole 1911, and the third connecting rod 19 can slide and retract in the first connecting rod 17. Specifically, the first end 15 is provided on the second connecting rod, and the second end 16 is provided on the third connecting rod 19. Furthermore, it also includes a first locking member 4. When the second connecting rod 18 is inserted into the second mounting hole 1711 through the second mounting hole 1711, the first locking member 4 is detachably connected to the first connecting portion 171, and the first locking member 4 locks the second connecting rod 18 in the second mounting hole 1711. Furthermore, the first locking member 4 is a first locking collar, and the inner wall of the first locking collar is pressed against the outer wall of the first connecting portion 171, so that the inner wall of the second mounting hole 1711 presses the second connecting rod in the second mounting hole 1711. Furthermore, it also includes a second locking member 5. When the third connecting rod 19 is inserted into the first connecting rod through the third mounting hole 1911, the second locking member 5 is detachably connected to the second connecting portion 191, and the second locking member 5 locks the third connecting rod 19 in the third mounting hole 1911. Furthermore, the second locking member 5 is a second locking collar, and the inner wall of the second locking collar is pressed against the outer wall of the second connecting portion 191, so that the inner wall of the third mounting hole 1911 presses the third connecting rod into the third mounting hole 1911. Through the above structure, since the second connecting rod 18 and the third connecting rod 19 can be telescopically adjusted in the first connecting rod, the length of the reel body 1 can be adjusted and adjusted, so that the reel body 1 can be adapted to curtains 2 of more sizes. Moreover, after the length of the reel body 1 is adjusted, the length of the reel body 1 can be fixed by the first locking member 4 and the second locking member 5.

[0054] In this embodiment, the first connection portion 171 is a first connection portion 171 that is narrow in front and wide in the back, and the second connection portion 191 is a second connection portion 191 that is narrow in front and wide in the back.
