Automatic translational electromagnetic shielding door

Abstract

The invention discloses an automatic translational electromagnetic shielding door. The door comprises a door frame, door leaves, a suspension assembly and a motor set. The suspension assembly comprises suspension wheels, sliding blocks fixedly connected to lower parts of the suspension wheels and sliding block guide rails fixedly connected with the door leaves. Tilting sliding grooves are arrangedin the sliding blocks. The sliding block guide rails are in slip fit with the titling sliding grooves in the sliding blocks. The top of the door frame and / or the bottom of the door frame and / is equipped with a tilting sliding groove / tilting sliding grooves. An inclination angle or inclination angles of the tilting sliding groove(s) is / are the same as the inclination angles of the sliding block guide rails. The door leaves are equipped with guide columns cooperating with the titling sliding grooves. When suspension wheels slide to the guide columns along translational sliding rails to enter the tilting sliding grooves, the door leaves towards the direction of the door frame in a titling and longitudinal direction through the sliding block guide rails along the titling sliding grooves in the sliding blocks. Through the translational sliding rails, translation of the door leaves is guided. The sliding block guide rails in the suspension assembly and the translational sliding rails are arranged in a tiling manner. Titling and longitudinal movement of the door leaves relative to the door frame is guided. Therefore, the door leaves kept stable during movement.

Description

Technical field [0001] The invention relates to an automatic translational electromagnetic shielding door, which belongs to the technical field of shielding doors. Background technique [0002] Translational electromagnetic shielding doors have existed for a long time. For many years, the translational electromagnetic shielding doors are mostly inflatable, that is, a pneumatic tire is set under the spring sheet. After inflation, the spring sheet contacts the shielding frame to achieve electromagnetic shielding. It has a simple structure and easy installation. The advantages. However, since most pneumatic tires are made of rubber, they are prone to aging and air leakage, and the uniformity of the wall thickness of pneumatic tires is difficult to ensure the uniformity of dimensions, especially the poor consistency at the four corners of the door frame, which is difficult to achieve on a flat surface. The uneven height difference is produced, resulting in inconsistent contact press...

Problems solved by technology

However, because most of the pneumatic tires are made of rubber, they are prone to aging and air leakage, and it is difficult to ensure the uniformity of the wall thickness of the pneumatic tire, especially the consistency of the four corners of the door frame. Uneven height differences are generated, resulting in inconsistent contact pressure of the spring leaf, which greatly affects the shielding performance
