[0034] Winding component: The two ends of the winding tube 8 are rotatably mounted on the support rod 15 via the front bushing 18 and the rear bushing 9 respectively; the spiral spring assembly 10 includes a spiral spring 21 and a spiral spring base 24, with the spiral spring 21 mounted on the spiral spring base 24.

[0035] Transmission components: The support rod insert 11 is fixedly connected to the rear bushing 9 and rotates together. The rear bushing 9 is sleeved on the support rod 15 and snapped to one end of the coil tube 8. The front bushing 18 is sleeved on the support rod 15 and snapped to the other end of the coil tube 8. The coupling 23 has a through hollow channel inside. One end of the support rod 15 extends through the hollow channel. One end of the coupling 23 is connected to the spiral spring 21, and the other end is fixedly connected to the support rod insert 11.

[0036] Protective and noise reduction components: heat shrink tube 12 is sleeved on support rod 15; small felt ring 13 and large felt ring 14 are arranged between two support rods 15; support rod flocking 16 covers the surface of support rod 15; threaded sleeve 17 is sleeved on support rod 15, and front shaft sleeve 18 is internally threaded; front shaft sleeve 18 can move left and right on threaded sleeve 17 through threaded cooperation;

[0037] Limiting components: lock spring 19 is used to prevent the rotation of vortex spring 21; limiting spring 22 is used to limit the movement range of shaft coupling 23.

[0038] As an embodiment, the connection relationship between pipe 8 and vortex spring assembly 10 in the embodiment is that pipe 8 is connected with shaft coupling 23 through support rod insert 11, and vortex spring assembly 10 cooperates with limiting spring 22.

[0039] As an embodiment, the specific connection mode of detachable components in the embodiment is that rear shaft sleeve 9 is connected with pipe 8 through buckling, front shaft sleeve 18 and rear shaft sleeve 9 are respectively sleeved with support rod insert 11, and front shaft sleeve 18 is threadedly cooperated with threaded sleeve 17 through internal threads.

[0040] As an embodiment, small felt ring 13 and large felt ring 14 are arranged between front shaft sleeve 18, rear shaft sleeve 9 and pipe 8 in the embodiment, and support rod flocking 16 is arranged on the surface of support rod 15.

[0041] As an embodiment, the energy transmission path of vortex spring assembly 10 in the embodiment is that the energy generated by vortex spring 21 is transmitted to pipe 8 through shaft coupling 23 and support rod insert 11 in sequence.

[0042] As an embodiment, edge sealing strip 4 is arranged to encapsulate and protect the edge of screen cloth 5 in the embodiment, and anti-skid lines are arranged on the surface of pipe 8.

[0043] The working principle is as follows:

[0044] When the user pulls handle plate 1, handle plate 1 rotates around handle plate shaft 2, and the force is transmitted to pull rod 3 through the principle of lever. Pull rod 3 drives screen cloth 5 on pipe 8, so that pipe 8 starts to rotate. Since pipe 8 is cooperatively installed on support rod 15 through front shaft sleeve 18 and rear shaft sleeve 9, the high-precision processing of front shaft sleeve 18 and rear shaft sleeve 9 ensures the stability of the rotation of pipe 8, and reduces shaking and friction. At the same time of the rotation of pipe 8, rear shaft sleeve 9 drives support rod insert 11 fixed thereto to rotate. At this time, vortex spring 21 in vortex spring assembly 10 is twisted, and starts to store elastic potential energy. Shaft coupling 23 transmits the power of vortex spring 21 to support rod insert 11, and then drives pipe 8 to rotate in the opposite direction to release screen cloth 5, so as to realize the unfolding of the sunshade curtain.

[0045] When it is necessary to retract the sunshade curtain, the pull handle plate 1 is loosened, and the elastic potential energy of the volute spring 21 is released. The energy generated by the volute spring 21 is transmitted to the winding pipe 8 through the shaft coupling 23 and the support rod insert 11 in turn, so that the winding pipe 8 rotates and the screen cloth 5 is wound on the surface of the winding pipe 8. In this process, the limit snap spring 22 limits the rotation angle of the winding pipe 8, the support rod insert 11 and other components, preventing excessive rotation, and the locking snap spring 19 prevents accidental rotation of the volute spring 21, ensuring the stability and reliability of the retraction process.

[0046] In the daily use of the sunshade curtain, the protection and noise reduction components play an important role. The small and large felt rings 13 and 14 are filled in the gaps between the front shaft sleeve 18, the rear shaft sleeve 9 and the winding pipe 8, effectively reducing the friction noise generated when the components rotate relative to each other, reducing wear and tear and prolonging the service life of the components. The support rod flocking 16 not only increases the friction between the components, making the connection more stable, but also uses its soft properties to buffer the collision between the components, further reducing noise. The heat shrink tube 12 tightly wraps around the connection part of the support rod 15, providing insulation, moisture resistance and wear resistance, protecting the internal structure from the external environment.

[0047] When it is necessary to maintain or replace components of the sunshade curtain, the advantages of its detachable design become apparent. The snap connection of the rear shaft sleeve 9 and the winding pipe 8, the sleeve connection of the front shaft sleeve 18 and the rear shaft sleeve 9 and the support rod insert 11, and the threaded connection of the front shaft sleeve 18 and the threaded sleeve 17 make it very convenient to disassemble and install the components. For example, if the winding pipe 8 needs to be replaced due to wear and tear, simply unscrew the front shaft sleeve 18 to separate it from the threaded sleeve 17, and then open the snap buckle of the rear shaft sleeve 9 and the winding pipe 8 to easily remove the winding pipe 8 for replacement, greatly reducing maintenance costs and difficulty.

[0048] Although the embodiments of the present application have been shown and described above, it should be understood that the above embodiments are exemplary and should not be construed as limiting the present application. Those skilled in the art can make changes, modifications, replacements and variations to the above embodiments within the scope of the present application.
