[0029] The present invention is further described in detail below with reference to the accompanying drawings and specific embodiments:

[0030] like Figure 1-Figure 5 As shown, a shutter quick-installation structure includes shutters 5 and beams 1 installed on both sides of the shutters 5.

[0031] In this embodiment, the louver 5 has first mounting holes 51 at both ends, and the fixing shafts 4 are respectively inserted into the first mounting holes 51 at both ends.

[0032] A pulley 2 is installed in the crossbeam 1 , and a second mounting hole 22 for connecting with the fixed shaft 4 is provided on the pulley 2 .

[0033] Specifically, a connecting shaft 21 is installed in the pulley 2 , and a second mounting hole 22 is opened on the connecting shaft 21 .

[0034] The fixed shaft 4 is connected to the crossbeam 1 through the pulley 2.

[0035] The second mounting hole 22 is opened at the center of the connecting shaft 21 , and the second mounting hole 22 is configured to be non-circular. In one embodiment, the second mounting hole 22 is configured to be a square hole with chamfers.

[0036] The first mounting hole 51 is also configured as a non-circular mounting hole. In one embodiment, the first mounting hole 51 is configured as a square.

[0037] Similarly, the fixed shaft 4 includes a first connection port 41 and a second connection port 42 . The first connection port 41 is configured as a square port that cooperates with the first mounting hole 51 , and the second connection port 42 is configured as a chamfered square hole that cooperates with the second mounting hole 22 .

[0038] Furthermore, the fixed shaft 4 is provided with a first through hole 43 at the center thereof, and steps 44 are provided on both sides of the first through hole 43 .

[0039] The first through hole 43 is used to install the cotter pin 3 .

[0040] The shape of the cotter pin 3 is set to be R-shaped. In the shape of the cotter pin 3, the shape of the right side of the R-shaped oblique side can be further designed to be wavy.

[0041] In this embodiment, the left vertical side strip of the cotter pin 3 is inserted into the first through hole, and the wave-shaped part on the right side contacts the step 44 on one side.

[0042] In this embodiment, a connecting rod 12 and a slide rail 11 are installed in the crossbeam 1 , and the pulley 2 is inserted into the crossbeam 1 via the connecting rod 12 .

[0043] As one embodiment, at least three pulleys 2 are installed in each crossbeam 1 . The pulleys 2 are installed with pulleys 23 at the bottom of both sides, and at least two pulleys 23 are installed on each side.

[0044] The slide rail 11 is used to cooperate with the lateral movement of the pulley 2. During the lateral movement of the pulley 2, the louver 5 moves synchronously through the fixed shaft 4. During the lateral movement, the fixed shaft 4 and the first mounting hole 51 and the second mounting hole 22 are non-circular in design and fixed by the cotter pin 3, so the louver 5 will not move axially.

[0045] In this embodiment, a rib 53 is further installed at the bottom of the louver 5 , and the rib 53 is placed in the second through hole 52 defined in the louver 5 .

[0046] A semicircular mounting groove is provided inside the second through hole 52 , and a clamping groove for cooperating with the rib 53 is provided.

[0047] Furthermore, baffles 54 are installed at both ends of the louver 5, and the baffles 54 are respectively provided with a first stop 55 and a second stop 56.

[0048] The first opening 55 is configured as a square opening adapted to fit the first connection port 41 of the fixed shaft 4 , and the second opening 56 is configured as a U-shape.

[0049] This design makes the louver 5 look more concise and beautiful.

[0050] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit the same. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that the technical solutions described in the aforementioned embodiments can still be modified, or some of the technical features thereof can be replaced by equivalents. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the various embodiments of the present invention.
