The moving connecting rod 204 drives the fixing rod 206 to move. The moving fixing rod 206 drives the bearing 207 to slide in the sliding groove 208 and the locking and limiting plate 209. When the bearing 207 contacts the inclined surface in the locking and limiting plate 209, the bearing 207 moves along the inclined surface to drive the whole shielding door panel 102 to be preliminarily separated from the main body support skeleton 101.

[0052] In one embodiment, the lighting mechanism 6 includes a glass window frame 601, two tempered insulating glass 602 and a nickel mesh 603;

[0053] Among them, the glass window frame 601 is installed on one side of the main body support skeleton 101. The two tempered insulating glass 602 are both fixedly connected to the inside of the glass window frame 601, and the nickel mesh 603 is arranged between the two tempered insulating glass 602;

[0054] The provided toughened insulating glass 602 is used to improve the lighting effect inside the shielding room, and a nickel mesh 603 is arranged between the two toughened insulating glasses 602 to ensure the overall shielding effect of the shielding room.

[0055] In one embodiment, two heavy-duty extended hinges 43 are symmetrically installed on one side of the main body support framework 101, and one side of each of the two heavy-duty extended hinges 43 is fixedly connected to one side of the shielding door panel 102.

[0056] The heavy-duty extended hinges 43 are used to connect the main body support framework 101 and the shielding door panel 102.

[0057] In one embodiment, a chassis 44 is fixedly connected to the bottom of the main body support framework 101, and an internal handle 45 is rotatably connected to the side of the shielding door panel 102 away from the external handle 201. One end of the internal handle 45 is fixedly connected to one end of the external handle 201.

[0058] By rotating the internal handle 45, the external handle 201 is driven to rotate synchronously, so as to open the shielding door panel 102 inside the shielding room. The provided chassis 44 is used to reduce the contact area between the shielding room and the ground.

[0059] When the present utility model is working: First, the whole device is moved and installed to a designated position according to actual needs. To make the installation of the whole device more convenient, a temporary lifting ring can be installed on the top of the main body support framework 101 or universal wheels can be installed at the bottom of the chassis 44, making the movement operation of the shielding room more convenient.

[0060] When it is necessary to open the shielding room, by rotating the external handle 201, the toothed ring 202 is driven to rotate. The rotating toothed ring 202 drives the connecting rod 204 to move upward by means of the rack 203. The moving connecting rod 204 drives the fixed rod 206 to move. The moving fixed rod 206 drives the bearing 207 to slide in the chute 208 and the locking limit plate 209.

[0061] The provided fireproof and heat-insulating rock wool 301 is used to improve the overall heat insulation and fireproof effect of the shielding room, and can achieve the purpose of no cavity inside the shielding room.

[0062] The provided tempered insulating glass 602 is used to improve the daylighting effect inside the shielding room. A nickel mesh 603 is arranged between the two pieces of tempered insulating glass 602 to ensure the overall shielding effect of the shielding room. When the daylighting width of the shielding room exceeds 1.2 meters, the tempered insulating glass 602 needs to be segmented, or it can be designed in an arc according to the building requirements. The wiring connection points of the shielding room can be shielded and connected using waveguide connectors, which are not shown in the figure.

[0063] When the shielding room needs to be closed, the shielding door panel 102 is moved to be preliminarily fitted with the main body support frame 101, so as to drive the reed slot 502 to squeeze the plug blade 501 by means of the shielding door panel 102, causing the reed slot 502 to deform under the action of pressure. When the bearing 207 contacts one side of the locking limit plate 209, the external handle 201 is rotated to drive the connecting rod 204 to move downward by means of the gear ring 202 and the rack 203. The moving connecting rod 204 drives the bearing 207 to slide into the locking limit plate 209 by means of the fixed rod 206 to close the main body support frame 101, and the tightness of the connection between the main body support frame 101 and the shielding door panel 102 is ensured by the provided plug blade 501 and reed slot 502, and contact conduction without dead angles around the shielding door panel 102 is achieved, thereby achieving a good shielding efficiency.
