The top of the main beam 2 is designed with a curved surface, and a triangular reinforcement plate is provided between the supporting main beam 2 and the baffle frame 9 .

working principle:

When replacing the shielding plate 602, tilt the shielding plate 602 to separate the limiting plate 601 from the mounting hole 5, then remove the single shielding plate 602, and set the mounting hole 5 to erect the limiting plate 601 and the shielding plate 602. During installation When shielding the plate 602, the six limiting posts 603 at the bottom of the limiting plate 601 are inserted into the clamping holes 7 to limit the position of the shielding plate 602, and one side of the two adjacent shielding plates 602 is embedded in the row. In the water tank 8, the rainwater falling between the two baffles 602 can be discharged along the drainage tank 8. When adjusting the sunshade and awning, the first bevel gear 101 is driven to rotate by the rotating handle 103, and the first bevel gear 101 drives the screw rod 11 to rotate through the second bevel gear 102. During the rotation of the screw rod 11, the nut 12 will move upward, so that the nut 12 can pull the connecting rods 13 on both sides to deflect at an angle, so that the bottom ends of the two connecting rods 13 Since the bottom end of the connecting rod 13 is hinged with the upright column 17 at the bottom of the scaffold 4, the two connecting rods 13 pull the two upright columns 17 closer to each other, causing the auxiliary pulley 18 at the bottom of the upright column 17 to roll on the ground. The top end is hinged with the scaffolding 4. During the movement of the column 17, the scaffolding 4 can be driven to deflect angularly, so that the two scaffoldings 4 drive the supporting main beam 2 to move upward, so that the supporting main beam 2 can slide on the portal frame 1. It slides in the channel 3 to keep the supporting main beam 2 moving upward vertically. Since the auxiliary pulley 18 is close to the main pulley 19, the entire sunshade canopy is narrowed, and the sunshade area can be adjusted.

From the above we know:

The rotating handle 103 drives the first bevel gear 101 to rotate, and the first bevel gear 101 drives the screw rod 11 to rotate through the second bevel gear 102. During the rotation of the screw rod 11, the nut 12 will move upward, so that the nut 12 can pull both sides. The side connecting rods 13 are angularly deflected, causing the bottom ends of the two connecting rods 13 to approach each other. Since the bottom ends of the connecting rods 13 are hinged with the upright columns 17 at the bottom of the scaffolding 4, the two connecting rods 13 pull the two upright columns 17 toward each other. , making the auxiliary pulley 18 at the bottom of the column 17 roll on the ground. Since the top of the column 17 is hinged with the scaffold 4, the scaffold 4 can be driven to deflect angularly during the movement of the column 17, so that the two scaffolds 4 drive the supporting main beams. 2 moves upward, so that the main support beam 2 can slide in the slide 3 on the mast 1, and the main support beam 2 is kept vertically moved upward. Since the auxiliary pulley 18 is close to the main pulley 19, the entire sunshade canopy is narrowed, and thus can Adjusting the shading area can be adapted to the operating needs in different scenarios, and at the same time it facilitates the transportation of the awning.

The limit plate 601 and the shielding plate 602 are set up by setting the mounting holes 5. When installing the shielding plate 602, the six limiting posts 603 at the bottom of the limit plate 601 are inserted into the holes 7 to limit the shielding plate 602. The function of the position prevents the deflection of the shielding plates 602 from affecting the waterproofing effect, and one side of the two adjacent shielding plates 602 is embedded in the drainage channel 8, so that the rainwater falling between the two shielding plates 602 can flow along the drainage channel. 8 is discharged to prevent water from penetrating under the supporting main beam 2, further improving the waterproof effect of the sunshade and awning. When replacing the shielding plate 602, tilt the shielding plate 602 to make the limit plate 601 separate from the installation hole 5, and then the single block can be blocked. The plate 602 is removed, maintained or replaced, and then embedded in the installation hole 5. Therefore, the modularly designed shielding plate 602 makes it more convenient to maintain the sunshade and awning, abandoning the traditional method of using an integrated shed plate, and reducing the difficulty of the work. .

The main pulley 19 provided at the bottom of the mast 1 and the auxiliary pulley 18 provided at the bottom of the column 17 can provide stable support to the sunshade and awning, facilitate the transfer of the sunshade and awning, and greatly improve the performance of the sunshade and awning. Wide application, because one of the baffle frames 9 has a sliding sleeve 16 and a sliding rod 15, the sliding sleeve 16 can slide freely outside the sliding rod 15, and supports the column 17 with the support rod 20 hingedly arranged outside the sliding sleeve 16, so that The supporting main beam 2 will not slide when moving and is more stable.
