Description

Technical Field

[0001] This application relates to the field of electromagnetic shielded door switching devices, and more particularly to a switching device for a track-type electromagnetic shielded door. Background Technology

[0002] Military command and communication sites must be able to resist electromagnetic interference. In extreme situations such as electromagnetic interference attacks or even nuclear explosions, combined with other protective factors, it is necessary to protect electronic communication equipment from damage and ensure its normal operation. Electromagnetic shielding rooms are workplaces built to meet the special requirements of electromagnetic pulse protection in the military field. Electromagnetic shielding doors are key structural components installed in electromagnetic shielding rooms. In order to meet the requirements of normal opening and closing in emergency situations, there are many requirements for the switch structure installed on electromagnetic shielding doors in practice.

[0003] For example, Chinese patent CN202222336661.4 discloses a fully automatic opening, closing, and locking electromagnetic shielded door, which "includes a fully automatic opening, closing, and locking electromagnetic shielded door. A control box is installed on the top of the fully automatic opening, closing, and locking electromagnetic shielded door. An opening is provided on the right side of the control box, and a fixed pipe is installed inside the opening. An air blowing fan is fixedly connected inside the fixed pipe. A water plate is installed on the right side of the top of the control box. This invention circulates the water in the water tank and the water plate through a circulating pump, cools the top of the water tank through a semiconductor cooling chip, and then blows air into the inside of the control box through an air blowing fan. This makes the control box of the fully automatic opening, closing, and locking electromagnetic shielded door have good heat dissipation, replacing the existing method of using a small fan for heat dissipation. Therefore, the heat dissipation of the control box is better, and the internal temperature of the control box will not be high, thus improving the heat dissipation of the control box of the fully automatic opening, closing, and locking electromagnetic shielded door."

[0004] For example, Chinese patent CN202221699532.5 discloses an electromagnetic shielding door with anti-lock function, "including a door frame, an electromagnetic shielding door body inside the door frame, an electric control switch fixedly connected to the left front of the electromagnetic shielding door body, a locking rod fixedly connected to the front of the electric control switch, a fixing sleeve on the outside of the locking rod, a handle fixedly connected to the lower right of the fixing sleeve, a limit block fixedly connected to the front of the locking rod, and a clamping plate on the outside of the handle. In this invention, through the handle, fixing sleeve, locking rod, and limit block, the electric control switch can be manually opened and closed by the handle under the action of the fixing sleeve and the limit block, preventing the electromagnetic shielding door body from being unable to open and close due to damage to the electric control switch, thereby ensuring the safety of personnel in emergency situations. Through the clamping plate, rotating wheel, and torsion spring, the handle can be easily positioned to prevent the handle from moving when not in use."

[0005] However, in practice, the electromagnetic shielding door switch structures in the aforementioned patents are all fully electrically controlled switch structures. In case of an emergency, such as a power outage, the shielding door cannot be manually opened, which greatly affects the evacuation of personnel in an emergency. Therefore, it is extremely urgent to design a switch device for electromagnetic shielding doors that can realize both electrical and manual opening control. Summary of the Invention
