The invention provides a spacecraft cabin door hinge device which is used on a spacecraft cabin door. The spacecraft cabin door hinge device comprises a support, a door body support, a sleeve and a handle, wherein the support is installed on a door frame of the spacecraft cabin door, the door body support can rotate relative to a support fixed shaft, the door body support is connected with the cabin door, the sleeve is installed on the right side of the support and connected with the handle, the handle is connected with a combination block, and the relative rotation of a right support shaft and the combination block can be limited or allowed through the contact and disengagement of the combination block and the door body support and the contact and disengagement of the combination block and the right support shaft. Compared with the prior art, the spacecraft cabin door hinge device has the advantages that the spacecraft cabin door hinge device can support the cabin door to rotate, the cabin door can be manually fixed to multiple positions and can be released, and operation is rapid and convenient.
Description
technical field [0001] The invention relates to a hinge device, in particular to a hinge device for a cabin door of a spacecraft. Background technique [0002] At present, in the known hinge device of the cabin door of spacecraft, all can support the cabin door to rotate. To prevent the door from opening [0003] In case of accidental rotation after opening, it is generally necessary to fix the hatch door through another fixing device or rope, and [0004] And the cabin door can only be fixed at a specific position, which is inconvenient to operate. Contents of the invention [0005] The object of the present invention is to provide a hinge device for a spacecraft door, to solve the problem that the existing hinge device for a door of a spacecraft generally needs to fix the door by another fixing device or ropes in order to prevent the door from accidentally rotating after opening, and The hatch can only be fixed at a specific position, which is a technical problem that...
