Detailed Implementation

[0019] The present invention will be further described below with reference to the accompanying drawings and embodiments, but this should not be construed as limiting the present invention.

[0020] Example: The structure of the large-span motorized venetian blind (application number 201921843379.7) was improved, such as... Figure 1 As shown, it includes an electric cylinder 1, a support mechanism, and multiple blades 2 arranged from top to bottom. The cross-section of the blades 2 is elliptical, the width of the blades 2 is horizontal, the material of the blades 2 is a hollow aluminum profile, and the wall thickness of the blades 2 is uniform. The electric cylinder 1 is connected to each blade 2 through a transmission mechanism. Both ends of the blades 2 are provided with tightly fitted adapters 20. The outer side of the adapters 20 is provided with a first rotating shaft 3, which is coaxial with the axis of the blades 2.

[0021] The supporting mechanism includes a column 4 located on the rear side of the blade 2 and a groove 5 located on the bottom of the blade 2. The groove 5 is actually a clearance hole opened at the bottom of the blade 2, which penetrates the bottom plate of the blade 2. A slider 15 is provided at the groove 5, which is slidably connected to the blade 2. The sliders 15 preferably have a slight tight fit, so that the sliders 15 can remain different after being pushed from the end of the blade 2 to the groove 5. A vertical mounting hole 16 is provided in the middle of the slider 15. A second rotating shaft 6 coaxial with the first rotating shaft 3 is provided at the mounting hole 16. The two ends of the second rotating shaft 6 are fixed to the two side walls of the mounting hole 16, respectively. The second rotating shaft 6 is connected to the column 4 through an L-shaped adapter plate 7. One end of the adapter plate 7 is fixed to the column 4, and the other end of the adapter plate 7 is provided with a rotating groove 17 that cooperates with the second rotating shaft 6. The bottom of the rotating groove 17 is semi-circular. The second rotating shaft 6 is located in the rotating groove 17. The adapter plate 7 supports the second rotating shaft 6, preventing the middle of the blade 2 from bending downward and also restricting the axial movement of the slider 15.

[0022] The electric cylinder 1 is rotatably connected to the column 4. The transmission mechanism includes a first adapter block 8 and a vertical rod 9 disposed on one side of the column 4. One end of the first adapter block 8 is rotatably connected to the output end of the electric cylinder 1, and the other end is fixed to the vertical rod 9. The vertical rod 9 is connected to the blade 2 through a second adapter block 10. One end of the second adapter block 10 is rotatably connected to the vertical rod 9. The other end of the second adapter block 10 is provided with a slot 19. A round rod 18 that cooperates with the slot 19 is provided on one side of the long axis of the blade 2. The round rod 18 is integrally formed on the blade 2.

[0023] The electric cylinder 1 is arranged at the upper end of the stand column 4, and the output end of the electric cylinder 1 is rotatably connected with the first adapter block 8 through a third rotating shaft 11; the second adapter block 10 is connected with the vertical rod 9 through a fourth rotating shaft 12; and the stand column 4 is rotatably connected with the electric cylinder 1 through a fifth rotating shaft 14.

[0024] Compared with the prior art, the embodiment has two improvements.

[0025] Firstly, the connecting structure between the adapter plate 7 and the second rotating shaft 6 is improved. The second rotating shaft 6 is fixed on the sliding block 15. Since the sliding block 15 is matched with the inner hole of the blade 2, the second rotating shaft 6 and the first rotating shaft 3 are automatically coaxial after the sliding block 15 is placed into the blade 2, and the assembly precision requirement is low. Meanwhile, the time for screwing on the blade 2 is saved, and the assembly is convenient.

[0026] Secondly, the round rod 18 is integrally formed on one side of the blade 2. The second adapter block 10 is connected with the round rod 18 through the clamping groove 19, and the connection between the blade 2 and the second adapter block 10 also does not need to be screwed, and the assembly is further convenient.

[0027] The embodiment is equivalent to the upgrade of the prior art. The working principle is unchanged. The electric cylinder 1 is extended and retracted to drive the second adapter block 10 to ascend and descend, and to drive one side of the blade 2 to ascend and descend, so that the blade 2 rotates around the first rotating shaft 3. The installation method is unchanged.
