Detailed Description

The shed is characterized in that a plurality of main beams 1 with main beam hinges 2 arranged at two ends are arranged in a zigzag manner along the longitudinal central axis of a square flexible shed top 7, and the main beams 1 are connected end to end through the main beam hinges 2; the rotation axis of the main beam hinge 2 is vertical to the flexible plane of the flexible shed top 7; each girder hinge 2 is provided with a fixed guide rod 3 and a movable guide rod 4 which respectively extend to two sides of the girder 1 along the transverse direction. A group of auxiliary beams 13 are arranged at the mirror image positions of each section of main beam 1 by taking the longitudinal central axis of the flexible shed top 7 as the axis, auxiliary beam hinges 15 are arranged at the two ends of each auxiliary beam 13, each auxiliary beam 13 is connected end to end through the auxiliary beam hinges 15, and the rotation axis of each auxiliary beam hinge 15 is vertical to the flexible plane of the flexible shed top 7. The middle point of the secondary beam 13 is connected with the middle point of the main beam 1 through a middle hinge 14 with the rotation axis vertical to the flexible plane of the flexible shed roof 7. That is, the main beam 1 and the auxiliary beam 13 form a serial scissors structure through the main beam hinge 2, the auxiliary beam hinge 15 and the middle hinge 14. In the series-connected scissors structure, one end of a fixed guide rod 3 is arranged on a main beam hinge 2, the other end of the fixed guide rod is fixedly provided with a fixed guide rod shed top connection point 5, and the fixed guide rod shed top connection point 5 is fixedly connected with the corresponding position of the longitudinal edge of a flexible shed top 7; one end of the movable guide rod 4 is arranged on the auxiliary beam hinge 15, and the other end of the movable guide rod passes through the movable guide rod sliding sleeve 16 and then is fixedly connected with the corresponding position of the longitudinal edge of the flexible shed roof 7 through a movable guide rod shed roof connecting point 6 fixedly arranged at the end head. The movable guide rod sliding sleeve 16 is fixedly arranged at one end of the fixed guide rod 3 at the main beam hinge 2. One end of an elastic cable 9 is connected with the middle position between two adjacent fixed guide rod shed top connection points 5 and a movable guide rod shed top connection point 6 on the longitudinal edge of the flexible shed top 7 through a cable shed top connection point 11, and the other end of the elastic cable is connected with an elastic cable driving point 12 arranged at a secondary beam hinge 15 by bypassing a pulley 10 arranged at a primary beam hinge 2.

The flexible shed top 7 covers the shearing fork structures connected in series, and the longitudinal edge of the flexible shed top 7 is fixedly connected with the fixed guide rod shed top connection point 5 and the movable guide rod shed top connection point 6 at corresponding positions. When the series scissors fork structure extends along the central axis, the fixed guide rod 3 and the movable guide rod 4 respectively extend towards two sides of the main beam 1, and after the series scissors fork structure extends along the central axis, the flexible shed top 7 is tightened under the combined action of the main beam 1, the fixed guide rod 3 and the movable guide rod 4. Because the height difference exists between the upper edge of the main beam 1 and the fixed guide rod shed top connection point 5 and the movable guide rod shed top connection point 6, the flexible shed top 7 forms a falling water slope with a high middle and two low edges after being tightened, and the falling of rainwater is facilitated.

When the flexible shed roof 7 needs to be folded, the serially connected scissors structure contracts along the longitudinal central axis, the auxiliary beam hinge 15 and the elastic cable driving point 12 move towards the direction far away from the main beam hinge 2, so that the elastic cable 9 is tensioned and pulls the longitudinal edge of the flexible shed roof 7 to move towards the direction close to the main beam hinge 2, and the flexible shed roof 7 near the fixed guide rod 3 is transversely folded and tensioned; meanwhile, a movable guide rod shed top connecting point 6 fixedly arranged at the end on the movable guide rod 4 moves towards the direction of closing the girder hinge, so that the longitudinal edge of a flexible shed top 7 is driven to move towards the direction of closing the girder hinge 2, and meanwhile, a hard folding sheet 8 originally transversely and straightly arranged along the movable guide rod 4 is changed into a zigzag arrangement, so that the flexible shed top 7 is driven to be transversely and normally folded. When the flexible shed roof 7 is transversely folded and closed to the main beam hinges 2 from two sides, the main beams 1 at all sections shrink in a zigzag manner along the longitudinal central axis of the square flexible shed roof 7, namely the transverse folding and closing and the longitudinal standard folding of the flexible shed roof 7 are simultaneously carried out. When the main beams 1 of all the sections are contracted and closed, the transverse folding and closing and the longitudinal standard folding of the flexible shed top 7 are completed simultaneously. The unfolding process and the folding and folding process of the flexible shed roof 7 are carried out in a reverse direction. After the flexible shed roof 7 is unfolded, the elastic guy cable 9 is in a loose state.
