The first linear guide rail 2.1.5 is horizontally arranged, and the first slider 2.1.4 is slidably connected to the first linear guide rail 2.1.5. The first linear guide rail 2.1.5 is connected to the left end of the first slider 2.1.4 at one end, and the third link 2.1.3 is connected to the right end of the first slider 2.1.4 at one end. The second linear guide rail 2.1.6 is vertically arranged and close to the end of the door body. The second slider 2.1.7 is fixedly connected to the end of the door body. The second linear guide rail 2.1.6 is slidably connected to the second slider 2.1.7 and has a vertical sliding degree of freedom.

[0062] In this embodiment, there is one first connecting rod 2.1.1, two second connecting rods 2.1.2, two first sliders 2.1.4, and two first linear guides 2.1.5, and four third connecting rods 2.1.3, two second linear guides 2.1.6, and four second sliders 2.1.7, all arranged symmetrically.

[0065] In some embodiments, please refer to Figures 1 to 6 Both sets of transverse tracks 1.4 are provided with mating holes. When the drive locking plate 2.2.1 is locked with the roller 1.3, the track wheel 2.5 enters the mating hole. When the door leaf 2 is in the closed state, the position of the track wheel 2.5 is the position of the mating hole, and the track wheel 2.5 can be inserted into the mating hole. Conversely, if the electric push rod 2.6 pushes in the opposite direction, the track wheel 2.5 can be pulled out of the mating hole.

[0066] In some embodiments, please refer to Figures 1 to 6 The manual operating device 2.3 includes a manual rotating shaft 2.3.1, a gear 2.3.2, and a rack mechanism 2.3.3. The manual rotating shaft 2.3.1 passes through the fan body, is rotatably connected to the inside of the fan body in the middle, and extends out of the fan body at both ends. One of the extended ends is used for manual gripping and turning. The axial direction of the manual rotating shaft 2.3.1 is perpendicular to the plane of the fan body. The gear 2.3.2 is located inside the fan body and is connected to the manual rotating shaft 2.3.1. The rack mechanism 2.3.3 is located inside the fan body and is meshed and connected to the gear 2.3.2. When the manual rotating shaft 2.3.1 rotates, it drives the gear 2.3.2 to rotate on the rack mechanism 2.3.3, thereby driving the rack mechanism 2.3.3 to move vertically. One side of the rack mechanism 2.3.3 is connected to the first connecting rod 2.1.1 and can drive the first connecting rod 2.1.1 to move vertically. Handwheels are connected to both ends of the manual rotating shaft 2.3.1, which are used for manual gripping and turning. When the manual rotating shaft 2.3.1 rotates, it can drive the gear 2.3.2 to rotate, and simultaneously drive the rack mechanism 2.3.3 to move vertically and the first connecting rod 2.1.1 to move up and down, thereby realizing the locking and unlocking of the door leaf 2 and the door frame 1. The rack mechanism 2.3.3 is a strip of rack, arranged vertically, and fixedly connected to one side of the first connecting rod 2.1.1.

[0067] In some embodiments, please refer to Figures 1-2The control system 4 has a communication port for connecting a monitor. This invention achieves fully automatic operation, meets shielding effectiveness requirements, and boasts advantages such as reasonable structure, stable performance, and high reliability. It also occupies a small space and offers both manual operation and remote monitoring capabilities. The monitor can be connected to the beam device 3 for real-time monitoring of the door leaf 2, thereby monitoring its operational status. Compared to existing technologies, this invention uses two power sources: the beam device 3 and an electric push rod 2.6, whereas existing technologies use three or more power sources. Furthermore, this invention enables lateral movement, longitudinal movement, and locking / unlocking actions. This invention is suitable for electromagnetic shielding rooms or shielded equipment rooms with a frequency band of 25Hz-40Hz, and possesses the same shielding effectiveness as the shielding body.

[0068] The specific operation of this utility model is as follows:

[0069] During the closing operation: the door leaf 2 moves laterally to the closed position under the drive of the crossbeam device 3. The electric push rod 2.6 inside the door leaf 2 drives the connecting rod slider mechanism 2.1 to operate and transmit power, thereby locking and closing the door leaf 2.

[0070] When opening the door, the electric push rod 2.6 is operated in the opposite direction, and the door leaf 2 moves longitudinally and unlocks. Driven by the crossbeam device 3, the door leaf 2 moves laterally to the opening position, completing the opening action.

[0071] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model.
