[0011] The beneficial effects achieved by the present utility model are as follows: The reel mechanism does not require external tools.

SPECIFIC EMBODIMENTS

[0019] The present utility model will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0020] Such as Figures 1-6As shown in the figure, a retractable skylight sunshade curtain reel mechanism of the present utility model includes a reel 1, a rotating terminal 2, a fixed terminal 3, a fixed steel shaft 4 and a torsion spring 5. The fixed steel shaft 4 and the torsion spring 5 are both arranged inside the reel 1. The rotating terminal 2 is arranged at one end of the reel 1, and the fixed terminal 3 is arranged at the other end of the reel 1. The torsion spring 5 is sleeved on the fixed steel shaft 4. One end of the fixed steel shaft 4 is provided with a torsion spring connection part 41, and the other end passes through the fixed terminal 3 at the end of the reel 1 and is fixed to the skylight main body through a first flattened position 42. One end of the torsion spring 5 is fixed on the torsion spring connection part 41, and the other end is fixed on the fixed terminal 3. The fixed steel shaft 4 is provided with a second flattened position 43 that cooperates with the fixed terminal 3. The fixed terminal 3 can move relative to the fixed steel shaft 4. When the fixed terminal 3 moves to the second flattened position 43, the second flattened position 43 restricts the rotation of the fixed terminal 3. When the fixed terminal 3 is disengaged from the second flattened position 43, the fixed terminal 3 can rotate along the axis of the fixed steel shaft 4. The reel mechanism of the present utility model does not require external tools, and the pre-tightening of the torsion spring 5 can be achieved through the cooperation of the second flattened position 43 and the fixed terminal 3, so as to ensure that the curtain cloth is tensioned and does not wrinkle during operation. Moreover, when disassembling this mechanism, the pre-tightening force of the torsion spring 5 can also be achieved through the cooperation of the second flattened position 43 and the fixed terminal 3 without being released.

[0021] In this embodiment, a steel shaft sheath 6 is sleeved outside the fixed steel shaft 3, and the torsion spring 5 is sleeved on the steel shaft sheath 6 to prevent the torsion spring 5 from directly contacting the fixed steel shaft 3. A torsion spring sleeve 7 is sleeved outside the torsion spring 5, and the torsion spring sleeve 7 is arranged between the torsion spring 5 and the reel 1 to prevent metal friction noise and surface scratches.

[0022] In this embodiment, the torsion spring connection part 41 is a plastic with rubber coating, and the plastic with rubber coating is provided with a torsion spring fixing hole, and one end of the torsion spring 5 is hung in the torsion spring fixing hole.

[0023] In this embodiment, a slotted opening 11 is opened at both ends of the reel 1, and the rotating terminal 2 and the fixed terminal 3 are both provided with limiting ribs that cooperate with the slotted opening 11. The rotating terminal 2 and the fixed terminal 3 can both rotate together with the reel 1.

[0024] Combined with Figure 6 As shown in the figure, in this embodiment, the fixed terminal 3 is provided with a limiting groove 31 that cooperates with the second flattened position 43. When the fixed terminal 3 is pulled outwards to disengage the limiting groove 31 of the fixed terminal 3 from the second flattened position 43, and then the fixed terminal 3 is rotated to drive one end of the torsion spring 5 to rotate, so that the torsion spring 5 generates a pre-tightening force, and then the fixed terminal 3 is pushed back to make the second flattened position 43 engage with the limiting groove 31 of the fixed terminal 3 to ensure that the pre-tightening force of the torsion spring 5 is not released. After the torsion spring 5 is pre-tightened, the torsion spring 5, the fixed steel shaft 4 and the fixed terminal 3 are loaded into the reel 1 together, and then the rotating terminal 2 and the fixed terminal 3 are respectively fixed at both ends of the reel 1, and the sub-assembly of the reel mechanism is completed.

[0025] When installing the scroll mechanism onto the skylight main body, first fix the first flattened position 42 of the fixed steel shaft 4 onto the skylight main body, and then push the scroll 1 to compress the total length of the scroll mechanism, so that the follower terminal 2 at one end of the scroll 1 is inserted into the skylight main body. At the same time, the limiting groove 31 of the fixed terminal 3 is disengaged from the second flattened position 43, enabling the scroll 1 to rotate forward and backward.

[0026] In this embodiment, the length of the scroll 1 is greater than the length of the fixed steel shaft 4, ensuring that the fixed steel shaft 4 and the fixed terminal 3 can achieve relative sliding during the disassembly and assembly process.

[0027] The above shows and describes the basic principles and main structural features of the present invention. The present invention is not limited by the above examples. Without departing from the spirit and scope of the present invention, the present invention will have various changes and improvements, and these changes and improvements all fall within the scope of the present invention claimed. The scope of protection claimed by the present invention is defined by the appended claims and their equivalents.
