[0023] In the following description, many specific details are set forth in order to fully understand the present invention. However, the present invention can also be implemented in other ways different from those described herein. Therefore, the present invention is not limited by the limitations of the specific embodiments disclosed in the following specification.

[0024] Embodiment 1, as Figure 1 - Figure 5 shown, the present invention provides a manual bead type louver curtain, including a window frame 1, a first straight rod 2 is fixedly installed inside the window frame 1, two limit ropes 3 are fixedly installed on the first straight rod 2, a second straight rod 4 is fixedly installed inside the window frame 1, and both ends of the two limit ropes 3 away from the first straight rod 2 are fixedly connected to the second straight rod 4. A plurality of louver boards 5 are movably threaded through the two limit ropes 3 together. A mounting seat 6 is fixedly connected inside the window frame 1. A placing groove 7 is opened on one side of the mounting seat 6. A bidirectional threaded rod 8 is rotatably connected inside the placing groove 7. The smooth end of the bidirectional threaded rod 8 movably penetrates through the placing groove 7 and extends to the outside of the mounting seat 6. Two mounting plates 9 are sleeved on the outer surface of the bidirectional threaded rod 8. A housing 10 is arranged on the opposite side of the two mounting plates 9. A winding mechanism 11 is arranged inside the housing 10. Two card slots 12 are opened at the top and bottom of the housing 10. Two card blocks 13 are fixedly connected to the opposite side of the two mounting plates 9.

[0025] The effect achieved by the entire Embodiment 1 is that by rotating the bidirectional threaded rod 8, since the placement groove 7 limits the two mounting plates 9, the bidirectional threaded rod 8 drives the two mounting plates 9 to move relatively. The two mounting plates 9 drive the two clamping blocks 13 to move relatively, so that the two clamping blocks 13 are driven to squeeze into the two clamping grooves 12, thereby enabling the clamping and installation of the housing 10 and the mounting base 6 together, facilitating the fixation of the housing 10 without the need for external tools. When disassembling the housing 10, by reversing the bidirectional threaded rod 8, the bidirectional threaded rod 8 drives the two mounting plates 9 to move away from each other. The two mounting plates 9 drive the two clamping blocks 13 to move away from each other, so that the two clamping blocks 13 are separated from the two clamping grooves 12, facilitating the disassembly of the housing 10, and it is convenient to use.

[0026] Embodiment 2, as Figure 1 - Figure 5 shown, a rotating rod 14 is rotatably installed inside the window frame 1. Two traction winding wheels 15 are fixedly sleeved on the outer surface of the rotating rod 14. Two traction ropes 16 are rotatably installed on the window frame 1. Both of the two traction ropes 16 are threaded through a plurality of louver boards 5. Both of the two traction ropes 16 pass through the first straight rod 2 and are movably connected thereto. Both of the two traction ropes 16 are wound around the correspondingly arranged traction winding wheels 15. A plurality of limiting spheres 17 are fixedly installed on both of the two traction ropes 16. A first bead winding wheel 18 is fixedly sleeved on the outer surface of the rotating rod 14. A bead rope 19 is rotatably installed on the window frame 1. The bead rope 19 is sleeved on the first bead winding wheel 18. The winding mechanism 11 includes a rotating shaft 110. The rotating shaft 110 is rotatably connected inside the housing 10. A second bead winding wheel 120 is fixedly sleeved on the outer surface of the rotating shaft 110. One end of the rotating shaft 110 movably penetrates through the housing 10. A rocker 130 is fixedly installed at one end of the housing 10. A through groove 140 is opened at the top of the housing 10. The end of the bead rope 19 away from the first bead winding wheel 18 is movably sleeved on the second bead winding wheel 120. A rotating handle 20 is fixedly installed on the outer surface of the bidirectional threaded rod 8. Two positioning grooves 21 are opened on one side of the mounting base 6. Two positioning blocks 22 are fixedly connected to one side of the housing 10.

[0027] The effect achieved by the entire Embodiment 2 is that by providing a winding mechanism 11, rotating the rocker 130 causes the rotating shaft 110 to drive the second bead winding wheel 120 to rotate. The second bead winding wheel 120 drives the bead rope 19 to move, and the bead rope 19 drives the first bead winding wheel 18 to rotate, so that the rotating rod 14 drives the traction winding wheel 15 to rotate. The traction rope 16 can be wound by the rotating traction winding wheel 15. At the same time, the limiting sphere 17 limits the louver 5. When the limiting sphere 17 moves upward along with the traction rope 16, the front end face of the louver 5 can be lifted upward. The rear end face of the louver 5 is penetrated by a limiting rope 3, which can effectively limit the rear end face of the louver 5, and thus the tilt angle of the louver 5 can be adjusted. When all the louvers 5 are tilted and overlapped, the louver curtain can be closed. If the rocker 130 is rotated in the reverse direction, the front end face of the louver 5 can be driven to move downward, and the louver curtain can be opened. It is convenient to use. By providing a turning handle 20, it is convenient to rotate the bidirectional threaded rod 8, improving the convenience. By inserting the positioning block 22 on one side of the housing 10 into the positioning groove 21, the position of the housing 10 can be positioned, facilitating its fixation.

[0028] Working principle: By inserting the positioning block 22 on one side of the housing 10 into the positioning groove 21, and then rotating the turning handle 20, the turning handle 20 drives the bidirectional threaded rod 8 to rotate. Since the placement groove 7 limits the two mounting plates 9, the bidirectional threaded rod 8 drives the two mounting plates 9 to move relatively. The two mounting plates 9 drive the two clamping blocks 13 to move relatively, so that the two clamping blocks 13 are driven to squeeze into the two clamping grooves 12, so that the housing 10 and the mounting seat 6 are clamped and installed together, facilitating the fixation of the housing 10 without the need for external tools. When disassembling the housing 10, by reversing the turning handle 20, the bidirectional threaded rod 8 drives the two mounting plates 9 to move away from each other. The two mounting plates 9 drive the two clamping blocks 13 to move away from each other, so that the two clamping blocks 13 are separated from the two clamping grooves 12, and then the positioning block 22 on one side of the housing 10 can be pulled out of the positioning groove 21. During use, by rotating the rocker 130, the rotating shaft 110 drives the second bead winding wheel 120 to rotate. The second bead winding wheel 120 drives the bead rope 19 to move, and the bead rope 19 drives the first bead winding wheel 18 to rotate, so that the rotating rod 14 drives the traction winding wheel 15 to rotate. The traction rope 16 can be wound by the rotating traction winding wheel 15. At the same time, the limiting sphere 17 limits the louver 5. When the limiting sphere 17 moves upward along with the traction rope 16, the front end face of the louver 5 can be lifted upward. The rear end face of the louver 5 is penetrated by a limiting rope 3, which can effectively limit the rear end face of the louver 5, and thus the tilt angle of the louver 5 can be adjusted. When all the louvers 5 are tilted and overlapped, the louver curtain can be closed. If the rocker 130 is rotated in the reverse direction, the front end face of the louver 5 can be driven to move downward, and the louver curtain can be opened. It is convenient to use.
