Problems solved by technology

However, this kind of pneumatic tire type shielding knife must have the support of compressed air source on the practical site, and the pneumatic tire made of elastic materials such as rubber will cause the aging of the pneumatic tire and lose its elasticity as the service life prolongs. Even a series of problems such as damage, air leakage, and adhesion of other parts adjacent to it will occur, which will seriously affect the normal operation of the air tire, and the electromagnetic shielding effect will be significantly reduced accordingly.

Abstract

The invention discloses a slotting tool-socket matching pair for an electromagnetic shield door, which comprises a door leaf frame (1) and a door seat frame (2); a socket (2) comprises a slot-type piece (3), left and right metal limiting pieces (4), left and right metal spring leaves (5) and left and right condition iron pieces (6); a slotting tool (D) comprises a slot-type plate (7), a magnetic yoke component (8), a copper flake (9), left and right press plates (10), a lower press plate (11) and a permanent magnetic rod (12); moreover, the slotting tool also comprises a permanent magnetic rod drive device (C). The slotting tool-socket matching pair has the characteristics of reasonable structure, reliable work, long-term normal and stable shielding effect and the like.

Description

technical field [0001] The invention relates to a knife socket matching pair for an electromagnetic shielding door, which belongs to the electromagnetic wave shielding equipment technology. Background technique [0002] The inserting knife and the socket are correspondingly arranged on the mating surfaces of the door leaf frame and the door seat frame respectively, so as to effectively avoid the leakage of electromagnetic waves. [0003] The existing knife socket matching pair is traditionally a knife switch structure. Its deficiency mainly lies in the large opening and closing force of the door leaf, especially under the condition that the metal reed included in it is corroded or stained, it will cause Electromagnetic waves leak, so that the shielding effect is significantly reduced. And the pneumatic tire type shielding inserting knife of recent research and development (applied for a patent before by the applicant). Utilizing the gain and loss of air of the pneumatic ti...
