DETAILED DESCRIPTION

[0022] In order to enable those skilled in the art to more clearly understand the technical solution of the present application, the present invention is further described below in conjunction with the accompanying drawings. Example 1

[0023] like Figure 1-Figure 4 As shown, a frame-type large blind can be rotatably arranged in a ring beam 10. The frame-type large blind includes a plate frame 1. Rotating parts 3 are arranged at both ends of the plate frame 1. The plate frame 1 can be rotatably matched with the ring beam 1 through the rotating parts 3. A plurality of louver plates 2 spliced ​​to each other are laid on the plate frame 1. A drainage groove 4 is arranged on one side of the louver plate 2, and a clamping groove 5 is arranged on the other side. The clamping groove 5 of the adjacent louver plates 2 is movably clamped and matched with the drainage groove 4. Specifically, the plate frame 1 includes side frames 11 and transverse frames 12 arranged opposite to each other. The transverse frame 12 is arranged at the ends of the side frames 11. The lower end face of the transverse frame 12 is flush with the lower end face of the side frames 11. The upper end face of the transverse frame 12 is lower than the upper end face of the side frames 11, forming a concave structure. The louver plates 2 are clamped on the concave structure to ensure the sealing between the louver plates 2 and the plate frame 1.

[0024] The louver 2 is made of iron, steel, aluminum or plastic. In order to strengthen the louver 2, concave-convex ribs 6 are provided on the louver 2, and the direction of the concave-convex ribs 6 is parallel to the slot 5 and the drainage groove 4. In this embodiment, the middle part of the louver 2, the end near the slot 5 and the end near the drainage groove 4 are all provided with concave-convex ribs 6. In order to strengthen the support strength of the plate frame 1, a plurality of reinforcing ribs 7 are further provided between the two side frames 11, and the upper end surface of the reinforcing ribs 7 is flush with the upper end surface of the cross frame 12.

[0025] In this embodiment, the slot 5 of the louver 2 is an L-shaped inverted slot, which is snapped on the side frame 11 on one side and exposed outside the side frame 11. The drainage slot 4 of the louver 2 is a U-shaped slot, which is snapped on the side frame 11 on the other side and exposed outside the side frame 11, and one side wall thereof abuts against the side of the side frame 11 away from the horizontal frame 12. Through the movable snap connection between the U-shaped slot and the L-shaped inverted slot, when the two are snapped together, the tent roof is in a closed state, ensuring the sealing of the closure and preventing the tent roof from leaking; when the two are separated, the tent roof is in an open state, increasing the lighting area of ​​the tent. Example 2

[0026] like Figure 5 and Figure 6As shown, a sheet metal tent comprises a column 8, a tent roof is arranged on the column 8, the tent roof comprises a ring beam 10 and the frame-type large blinds in Example 1, a plurality of large blinds are movably connected and laid in the ring beam 10 in sequence; a driving member 9 is arranged on the ring beam 10, and the driving member 9 is linked with the rotating shaft 31 of the large blinds (the linkage between the driving member 9 and the rotating shaft 31 of the large blinds is the same as the driving method of the existing blind tent, which is not introduced here), and the large blinds are driven by the driving member 9 to rotate synchronously in the same direction to realize the opening and closing of the large blinds (that is, the separation and connection of adjacent large blinds).

[0027] Based on the large shutter structure in Example 1, a rotating member 3 is arranged on the outer wall of the transverse frame 12 of the plate frame 1. The rotating member 3 is a "Ji" type frame. The bottom walls on both sides of the "Ji" type frame are fixedly connected to the transverse frame 12 by fixing members, and a rotating shaft 31 is arranged on the top wall in the middle of the "Ji" type frame. The rotating shaft 31 cooperates with the mounting assembly 32 to be connected to the ring beam 10. The mounting assembly 32 includes a snap-fit ​​member 321, a snap-fit ​​hole is arranged on the snap-fit ​​member 321, and a limiting member 322 is arranged on one side of the snap-fit ​​member 321, and the snap-fit ​​member 321 and the limiting member 322 are connected by a connecting member 323; the snap-fit ​​member 321 is snapped into the mounting hole arranged on the ring beam 10, the rotating shaft 31 is inserted into the snap-fit ​​hole, and the limiting member 322 is synchronously snapped onto the rotating shaft 31 to limit the rotating shaft 31.

[0028] In this embodiment, the mounting assembly 32 (i.e., the buckle 321, the limiter 322 and the connector 323) is made of plastic material, which can convert the rotational fit between the rotating shaft 31 and the ring beam 10 into a soft friction of plastic between the mounting assembly 32, which is convenient for the replacement of accessories after wear and tear, and can also avoid the wear of the rotating shaft 31 and the ring beam 10. Among them, the buckle 321 is an annular ring, and the inside of the annular ring is a clamping hole. The annular end surface of the annular ring is provided with a U-shaped annular groove, which is clamped with the mounting hole through the U-shaped annular groove. A key groove is provided on one side wall of the U-shaped annular groove, and the other side wall is connected to the connector 323; the connector 323 is a C-shaped ring, one end of which is connected to the U-shaped annular groove, and the other end is connected to the limiter 322; the limiter 322 is a C-shaped buckle, and the inside of the C-shaped buckle is a limiter groove. The rotating shaft 31 is sequentially inserted into the limiter groove and the clamping hole to achieve connection with the ring beam 10.

[0029] The large blinds are installed with mounting holes on both sides of the ring beam 10. When installing, first, the buckle 321 is embedded in the mounting holes of the ring beams 10 on both sides through the U-shaped ring groove; then the rotating shaft 31 on the rotating member 3 on one side of the large blind is sequentially passed through the limiting hole of the limiting member 322 and the clamping hole of the buckle 321 and installed on one side of the ring beam 10; then the rotating shaft 31 on the other side of the large blind is sequentially passed through the limiting groove of the limiting member 322 and the clamping hole of the buckle 321 and installed on the other side of the ring beam 10. During installation, the rotating shaft 31 is limited by the limiting member 322 to prevent the rotating shaft from falling off, thereby ensuring the safety and stability of the installation and use of the large blinds; the latch-type buckle limiting structure reduces the number of parts and facilitates assembly.
