Shielding pneumatic fan-shaped door
The invention discloses a shielding pneumatic fan-shaped door. The shielding pneumatic fan-shaped door comprises a door frame and a door body, wherein the door body is hinged to the door frame, an outer handle is rotationally connected to the door body, and the outer handle penetrates through the door body through a rotating shaft and is connected with an inner handle. According to the shielding pneumatic fan-shaped door, a first spur rack, a second spur rack and a spur gear are driven by an air cylinder to conduct reciprocating linear conduction, the first spur rack, the second spur rack, a connecting rod and a limiting rod are limited and guided through a needle bearing and a linear bearing, the rotating shaft is sleeved with the two sets of inner bearings, it is guaranteed that the position of the rotating shaft is stable, the spur gear can be better connected to rotate, therefore the structure stability is improved, a conical knife and a L-shaped knife are matched with beryllium copper reeds, and the conical knife and the L-shaped knife are in uniform compression contact with the beryllium copper reeds on the inner sides of the double U-shaped grooves, so that the periphery has a continuous conductive function, electromagnetic waves cannot interfere and enter the interior, the shielding effect between the door frame and the door body is improved, and the shielding door can be directly opened through manual operation, and the safety is high.
本发明公开一种屏蔽气动扇形门，包括门框和门体，所述门体铰接安装在门框上，所述门体上转动连接有外把手，所述外把手通过转动轴贯穿门体并连接有内把手；本发明通过气缸驱动第一直齿条、第二直齿条与直齿轮作往复直线传导，并通过滚针轴承和直线轴承对第一直齿条、第二直齿条、连杆以及限位杆作限位导向，并在转动轴上套接两组内轴承保证转动轴的位置稳定，能更好的连接直齿轮转动，从而提高了结构稳定性，通过锥形刀及L型刀结构与铍铜簧片配合，锥形刀与L型刀分别与双U型槽内侧的铍铜簧片均匀压缩接触，使得周围具备延续导电功能，电磁波无法干扰及进入到内部，提高了门框和门体之间的屏蔽效果，且可以直接手动操作开启屏蔽门，安全性较高。
