Description
The present invention relates to a door for an electromagnetic shielding room, and more particularly to a door for an electromagnetic shielding room that can provide a wider open area in opening and closing of the door, and can block the electromagnetic waves safely, and also enable stable opening and closing. .
With the development of electronic and electrical equipment, electromagnetic waves are generated in most of life, and these electromagnetic waves affect not only the human body but also other electronic and electrical products.
Many industrial products, including electronics and automobiles, use electromagnetic shielding rooms that block the inflow and outflow of electromagnetic waves to test the occurrence of electromagnetic waves on the products. In this case, the shielding rooms themselves form a complete electromagnetic shielding structure. Blocking electromagnetic waves in doors for entry and exit has emerged as an important challenge.
Accordingly, many researches have been made on the coupling part between the door constituting the door and the door frame of the shielded room, and various techniques have been proposed to make the door and the shield door close together.
Most of the conventional doors for shielding rooms are made of a casement type, and thus the casement type door does not provide a sufficient space for opening, which causes a lot of inconvenience when entering or exiting various materials or appliances.
The conventional shielding room door is made of a single door, and the main reason is to increase the confidentiality of electromagnetic waves, the more wide the form of the door becomes more difficult to block the electromagnetic waves, two or more doors, for example When it is in the form, it is difficult to maintain the confidentiality of electromagnetic waves and the like to the contact portion of the door has been used dareul door type daringly.
Therefore, there is an urgent need for the development of a door for a shielded room, which can be kept wider, and therefore also confidential.
The present invention is to provide a door for an electromagnetic shielding room that can provide a wider open space in the door of the electromagnetic shielding room while blocking the airtightness of electromagnetic waves.
The present invention is to install a door of the electromagnetic shielding room in the form of a pair of opening and closing the electromagnetic wave shielding room so that the electromagnetic shielding can be made safely by forming a combined structure that can maintain a stable airtight while securing a wider open space The provision of the door is a technical problem.
In order to realize the above object, the present invention provides a door for an electromagnetic shielding room, which is installed in the form of a case in a door frame of an electromagnetic shielding room so as to open and close the entrance and exit of the shielding room, wherein the door has a first door and a second door. When the first and second recesses which are bent inwardly are formed to protrude to different sizes at each end of the first door and the second door that are in contact with each other, and the doors are closed. It is characterized in that either one of the first recessed portion or the second recessed portion is fitted into one of the other recessed portions.
Accordingly, by forming a form in which the side of the two doors that are in contact with the side is completely in close contact can be stably maintained airtight.
An elastic piece having a convex shape is further attached to a side surface of the first recessed part and the second recessed part so as to cushion the impact by the elastic coupling when the first recessed part and the second recessed part are joined, and also provide more perfect airtightness. It can be maintained, and may be configured to block the electromagnetic waves according to the material of the elastic piece.
Another feature of the present invention, the remaining edge portions of the first door and the second door except for the side of the first door and the second door as a pair of doors are protruded inward to form a coupling protrusion, the door frame to the coupling A coupling recess is formed to accommodate the protrusion, and the inner side of the coupling recess is provided with an elastic piece to be tightly coupled by elasticity when coupling with the coupling protrusion.
Accordingly, the airtightness can be safely maintained at the contact surface of the first door and the second door as well as the remaining edge portion.
The present invention provides a wider open space when opening and closing the door, while still providing the effect that the airtightness of the contact portion of the door can be made safely.
The door according to the present invention is provided with a pair of opening and closing to provide a wider open space, and also has the effect of maintaining the airtightness such as electromagnetic waves by having a close coupling structure in the contact portion of each door.
