Description

Technical Field

[0001] This utility model relates to a folding weatherproof door, belonging to the field of marine technology. Background Technology

[0002] To ensure a high level of watertightness, some compartments on ships are typically equipped with watertight doors to achieve a sealing effect. However, most current compartment doors are designed with the door panel and frame connected on the side by a hinge mechanism, allowing them to open by rotating left and right. This design requires space to be left along the path of the door opening to the left and right within the compartment. Therefore, space must be reserved on one side and behind the side of the door, which puts considerable strain on the already limited space on the ship, thus hindering the efficient use of compartment space. Utility Model Content

[0003] The purpose of this invention is to overcome the above-mentioned shortcomings and provide a folding weatherproof door that can save cabin space.

[0004] The purpose of this utility model is achieved as follows:

[0005] A folding weatherproof door includes a door frame and a door panel assembly. The door panel assembly is connected to the door frame via a hinge device. The door panel assembly mainly includes an upper door panel and a lower door panel. The top of the upper door panel is hinged to the door frame via a hinge lug. A hinge plate is provided on the side of the upper door panel near the bottom and on the side of the lower door panel near the top. The two hinge plates are connected by a hinge member. A hinge seat is installed on each side of the door frame at the same height. A hinge seat is also installed on the rear side of the upper door panel near the left and right sides. The left hinge seat of the door frame and the left hinge seat of the upper door panel are hinged to both ends of a hydraulic cylinder. The right hinge seat of the door frame and the right hinge seat of the upper door panel are hinged to both ends of another hydraulic cylinder. Rollers are installed on both sides of the bottom of the lower door panel. A track is provided inside the door frame near the door panel, and the rollers slide up and down in the track.

[0006] The door panel assembly is also equipped with a locking device and an opening and closing device.

[0007] This utility model provides a folding weatherproof door with the following advantages:

[0008] This type of folding weatherproof door consists of two halves, an upper and a lower half, hinged together. The upper half is rotated by a hydraulic cylinder, while the bottom of the lower half slides along a track within the door frame. This allows the upper half to be pushed open while the lower half folds. This reduces the space required for opening the door, allowing for more flexible cabin design. Attached Figure Description

[0013] like Figures 1 to 3 This utility model relates to a folding weatherproof door, including a door frame 1 and a door panel assembly 2. The door panel assembly 2 is connected to the door frame 1 by a hinge device 3. The door panel assembly 2 is also equipped with a locking device 4 and an opening and closing device 5. The locking device 4 is used to lock or unlock the door panel assembly 2, and the opening and closing device 5 is used to open or close the door panel assembly 2.

[0014] The door panel assembly 2 mainly includes an upper door panel 6 and a lower door panel 7. The top of the upper door panel 6 is hinged to the door frame 1 through a hinge lug. A hinge plate 8 is provided on the side of the upper door panel 6 near the bottom and on the side of the lower door panel 7 near the top. The two hinge plates 8 are connected by a hinge, so that the upper door panel 6 and the lower door panel 7 can rotate relative to each other and fold up.

[0015] A hinge seat 9 is installed on each side of the door frame 1 at the same height. A hinge seat 9 is also installed on the rear side of the upper door panel 6 near the left and right sides. The left hinge seat 9 of the door frame 1 and the left hinge seat 9 of the upper door panel 6 are hinged to both ends of a hydraulic cylinder 10. The right hinge seat 9 of the door frame 1 and the right hinge seat 9 of the upper door panel 6 are hinged to both ends of another hydraulic cylinder 10. After the hydraulic cylinder 10 extends or retracts, it can drive the upper door panel 6 to open upward or close downward.

[0016] The bottom of the lower door panel 7 is equipped with pulleys 11 on both sides, while the interior of the door frame 1 has a track 12 near the door panel, in which the pulleys 11 slide up and down. After the hydraulic cylinder 10 drives the upper door panel 6 to rise and fall, the top of the lower door panel 7 is pulled up and down, and the bottom of the lower door panel 7 rises and falls along the track 12, thus completing the folding together. Furthermore, because the upper door panel 6 and the lower door panel 7 are hinged together, the bottom of the lower door panel 7 is confined in the track, so when the hydraulic cylinder 10 is fully lifted, the lower door panel 7 will not fall down.
