DETAILED DESCRIPTION

[0022] Combine the following Figure 1-4 The utility model is described in detail.

[0023] A hydraulic folding door comprises a door leaf body 10, wherein the door leaf body 10 comprises an upper door leaf 101 pivotally connected to the top of a wall opening and a lower door leaf 102 pivotally connected to the upper door leaf 101, wherein guide rails 20 are slidably adapted on both sides of the lower door leaf 102, and the guide rails 20 are installed on opposite sides of the wall opening; and further comprises at least one hydraulic drive device 30, wherein a mounting end 301 of the hydraulic drive device 30 is installed on the wall, and an output end 302 of the hydraulic drive device 30 is pivotally connected to the inner side of the upper door leaf 101, and the opening and closing of the door leaf body 10 is controlled by the extension and contraction of the output end 302 of the hydraulic drive device 30. The folding door does not require a storage area after the door leaf body 10 is opened, and the door body of the folded door is above the outer side of the building, and only occupies the upper space, and the opening and closing of the door leaf body 10 is controlled by the hydraulic drive device 30, which saves manpower and is simple and convenient. Specifically, the mounting end 301 of the hydraulic drive device 30 is installed on the indoor wall.

[0024] In this embodiment, the guide rail 20 includes a guide rail 20 groove, and sliding parts 1021 slidably adapted to the guide rail 20 groove are installed on both sides of the lower door leaf 102 .

[0025] In this embodiment, the guide rail 20 is connected to a first force-bearing bracket 401 , and the wall is provided with a second force-bearing bracket 402 . The first force-bearing bracket 401 and the second force-bearing bracket 402 are arranged opposite to each other.

[0026] In this embodiment, the number of hydraulic drive devices 30 is three. Compared with the arrangement of one hydraulic drive device 30, the arrangement of three hydraulic drive devices 30 is more stable and safer when opening and closing the door leaf body 10. Specifically, the hydraulic drive device 30 is a hydraulic actuator, which is a power conversion device that converts hydraulic energy into mechanical energy to provide driving force for various transportation carriers, test systems, and mechanical engineering. Specifically, the three hydraulic drive devices 30 are arranged side by side, and their mounting ends 301 are installed at the same horizontal height, and their output ends 302 are pivotally connected to the same horizontal height position on the inner side of the door leaf 101.

[0027] In this embodiment, a fixing seat 1011 is provided on the inner side of the upper door leaf 101, and the output end 302 of the hydraulic drive device 30 is pivotally connected to the fixing seat 1011. Specifically, the number of the fixing seats 1011 is three.

[0028] In this embodiment, it also includes a first steel door axis 501 and a second steel door axis 502. The upper door leaf 101 is pivotally connected to the top of the wall opening through the first steel door axis 501, and the lower door leaf 102 is pivotally connected to the bottom of the upper door leaf 101 through the second steel door axis 502.

[0029] In this embodiment, the door leaf body 10 includes an indoor layer 103 and an outdoor layer 104. The indoor layer 103 is made of thick steel plate, and the outdoor layer 104 is made of Et board. Specifically, the thickness of the thick steel plate and the Et board is 2 mm, and the color of the Et board is consistent with the color of the exterior wall.

[0030] In this embodiment, rock wool 105 is filled between the indoor layer 103 and the outdoor layer 104 .

[0031] The hydraulic folding door proposed by the utility model has the following working principle:

[0032] To open the folding door in the closed state: start the hydraulic drive device 30 to extend its output end 302, and then the output end 302 of the hydraulic drive device 30 drives the upper door leaf 101 to move toward the outside of the room, and as the upper door leaf 101 moves outward, the lower door leaf 102 slides upward on the guide rail 20; when the upper door leaf 101 and the lower door leaf 102 move to the specified position, the output end 302 of the hydraulic drive device 30 stops extending, at this time the upper door leaf 101 and the lower door leaf 102 are fixed by the hydraulic drive device 30, and the folding door is opened.

[0033] To close the folding door in the open state: start the hydraulic drive device 30 to shorten its output end 302, and then the output end 302 of the hydraulic drive device 30 drives the upper door leaf 101 to move toward the room, and as the upper door leaf 101 moves inward, the lower door leaf 102 slides downward on the guide rail 20; when the upper door leaf 101 and the lower door leaf 102 move to the specified position, the output end 302 of the hydraulic drive device 30 stops shortening, and the folding door is now closed.

[0034] The above embodiments are only for illustrating the technical concept and features of the utility model, and their purpose is to enable those skilled in the art to understand the content of the utility model and implement it, and they cannot be used to limit the protection scope of the utility model. Any equivalent changes or modifications made according to the spirit of the utility model should be included in the protection scope of the utility model.
