[0018] In order to make the purpose, technical scheme and advantages of the utility model more clear, the utility model is further described in detail in the following with reference to the drawings and examples, and it should be understood that the specific examples described herein are only used to explain the utility model, and are not used to limit the utility model.

[0019] Referring toFigure 1 、 Figure 2 、 Figure 3 and Figure 4 The utility model provides a kind of heat-insulated metal door, the heat-insulated metal door includes the door body 1 filled with heat-insulating material (such as paper shell, polyester fiber foam etc.), the door body 1 is provided with expansion body 2 (capsule structure) along its end face around the periphery end face corresponding with door frame, expansion body 2;The application utilizes expansion body 2 to seal the gap between door body 1 and door frame in door closing state, to reduce the heat flow between required space and outside.

[0020] The periphery end face is provided with containing bin 3 for receiving expansion body 2;In the door body 1 in door opening state, expansion body 2 is in dry state and is received in containing bin 3, can be placed when opening and closing door, and expansion body 2 is damaged by extrusion of door frame.

[0021] Expansion body 2 is filled with fluid (such as air, water or other fluid) for driving its expansion, and the internal space of expansion body 2 is in communication with a storage bin 4 arranged in the door body 1, and the storage bin 4 is provided with a fluid driving structure to selectively drive the fluid to the expansion body 2 or the storage bin 4. When the fluid flows from the storage bin 4 into the expansion body 2, the expansion body 2 enters the expansion state, and when the fluid flows from the expansion body 2 into the storage bin 4, the expansion body 2 is in the dry state.

[0022] The fluid driving structure is a piston structure. The fluid driving structure is connected to a rotating component.

[0023] The fluid driving structure includes an arc-shaped fluid containing chamber 41 and a piston 42 moving in the fluid containing chamber 41, and the piston 42 is connected to the rotating component. The rotation of the rotating component drives the piston 42 to move along the extension direction of the fluid containing chamber 41 to generate a pressure that drives the fluid to move. In this embodiment, the rotating component is a rotating handle 5 or other knob structure. It should be noted that the above-mentioned piston 42 is connected to the rotating component, which can not be directly connected, that is, it can be indirectly driven by a gear structure, and the connection mode is specific according to the space distribution.

[0024] After opening or closing the door body 1, the rotating handle 5 is rotated to drive the piston 42 to move along the extension direction of the fluid containing chamber 41 to generate positive pressure or negative pressure. If positive pressure is generated, the fluid is extruded to flow into the expansion body 2 to drive it to expand. If negative pressure is generated, the fluid in the expansion body 2 is sucked into the containing chamber 41 to drive the expansion body 2 to enter the dry state.

[0025] Preferably, the surface of the expansion body 2 of the utility model is provided with a plurality of auxiliary sealing strips 7 ( Figure 4The door body 1 is provided with a set of expansion bodies 2 corresponding to each end face, and the auxiliary sealing strips are detachably connected with the expansion bodies 2 (for example, the auxiliary sealing strips are connected with the expansion bodies 2 through magic bands or adhesive bands)

[0026] In addition, the two auxiliary sealing strips 7 are symmetrically arranged at the side ends of the expansion body 2. In this arrangement, the auxiliary sealing strips do not affect the storage of the expansion body 2. When the expansion body 2 is in a deflated state, the auxiliary sealing strips are in a horizontal state. When the expansion body 2 is inflated, the auxiliary sealing strips change from the horizontal state to the vertical state.

[0027] In summary, the utility model provides a kind of heat insulation metal door, including the door body filled with heat insulation material (such as paper shell, polyester fiber foam etc.), the door body is provided with expansion body (capsule structure) corresponding to the periphery end face of door frame, expansion body is along its end face and is surrounded;The utility model utilizes expansion body to seal the gap between door body and door frame in closed state, to reduce the heat flow between required space and outside.
