Flexible curled-edge wave-inhibiting shield door

Abstract

The invention discloses a soft curling shielding door against wave, comprising a shielding tarpaulin; U-type slot on the shielding tarpaulin, which divides the shielding door into shielding portiere and door frame; slide fastener connecting shielding portiere and door frame; a first internal door sleeve and external door sleeve connecting with the edge of shielding portiere, a second internal door sleeve and external door sleeve connecting with the edge of shielding door frame; cingulated set at inner and outer sides of shielding portiere and door frame. There is door sleeve connecting with edges of shielding portiere and door frame. In using the electromagnetic wave leaked from door sew is entirely isolated by the curling of door sleeve. The shielding function of door is in accordance with shielding body. It is provided with reliable function. The door can open and close in and out of the sail. Because the door and the sail are the same shielding material it is provided with good durability. There is no added part in the structure and it is made of the shielding material. It is provided with less material for use and low cost.

Description

technical field [0001] The invention belongs to a flexible electromagnetic shielding tent for preventing electromagnetic leakage and electromagnetic pulse, in particular to a flexible rolling-edge electromagnetic shielding door. Background technique [0002] In recent years, different types of electromagnetic shielding tents have been developed successively at home and abroad, but the shielding door is always one of the technical bottlenecks. The shielding doors of foreign electromagnetic shielding tents are mainly combined with shielding zippers, Velcro and strong magnetic strips, that is, when closing the door, first use the shielding zipper to close the flexible door, and then use a strip of metal wave-absorbing Velcro to adhere for a week along the seam of the shielding zipper. Then use the door curtain with strong magnetic strips on the periphery to stick on the door frame along the outer edge of the Velcro. The Velcro and strong magnetic strips are mainly to enhance wa...

Problems solved by technology

The shielding doors of foreign electromagnetic shielding tents are mainly combined with shielding zippers, Velcro and strong magnetic strips, that is, when closing the door, first use the shielding zipper to close the flexible door, and then use a strip of metal wave-absorbing Velcro to adhere for a week along the seam of the shielding zipper. Then use the door curtain with strong magnetic strips on the periphery to stick on the door frame along the outer edge of the Velcro. The Velcro and strong magnetic strips are mainly to enhance wave absorption and prevent electromagnetic waves from shielding the zipper seam leakage. This kind of screen door has a complicated structure and poor practicability. The door can only be opened and closed from inside the canopy

Domestically, the labyrinth multi-shield zipper door or simple steel shield door is mainly used. The labyrinth multi-shield zipper door is mainly composed of three to five shield zippers. The shielding frequency band is narrow and the shielding efficiency is low. Easy to deform after disassembly, causing electromagnetic leakage, not suitable for shielding tents that need to be erected and withdrawn repeatedly
