The sound-insulation electromagnetic shielding gate has a compact structure and double effects of shielding electromagnetic waves and the sound waves and is capable of effectively preventing leakage of electromagnetic signals and sound information.
Description
Technical field
The utility model relates to electromagnetic shielding and information security field, is specifically related to a kind of secret conference room and the three anti-conference room-based Multifunctional shield doors that prevent information leakage.
Background technology
In order to prevent the leakage of important information, a lot of meetings all need to be held in secret conference room.The multiple preventing functions such as secret conference room requires to have anti-acoustical leakage, far infrared imagery, anti-eavesdrop are leaked, prevented to anti-electromagnetic signal, prevent taking on the sly.Shield door on secret conference room plays a part very important to the shield effectiveness of whole secret conference room.In order to reach secret effect, the General Requirements shield door must have the function of shielding electromagnetic wave and sound wave and need to satisfy the relevant regulations of national secret standard BMB26-2012.
But, use the shield door field at conference room at present, commonly used is all to shield electromagnetic electromagnetic shield door, and its design feature is to comprise doorframe and door leaf, and a side of door leaf is hinged by hinge and doorframe, and opposite side arranges retaining mechanism; The edge of door leaf is provided with the shielding knife plate, and doorframe is provided with shielding knife plate and shields accordingly the cutter groove, is provided with the double-reed in order to clamping shielding knife plate in the inner chamber of shielding cutter groove.When shield door was in closed condition, the shielding knife plate was inserted in the gap of double-reed, and with the double-reed close contact, link together thereby will shield doorframe and shield door leaf, consist of a complete electromagnetic shield.This shield door can effectively shield electromagnetic wave signal, but soundproof effect is poor.
Chinese patent CN2806724 discloses a kind of Multifunctional electromagnetic shield door, comprises doorframe and door leaf, and a side of described door leaf is hinged by hinge and doorframe, and opposite side is provided with retaining mechanism; Door leaf is provided with the shielding knife plate, and doorframe is provided with shielding cutter groove correspondingly, is provided with reed in shielding cutter groove; In addition, this patent is also by arranging the sound insulating member that is made of support, foamed plastics, magnetic stripe and rubber in the door leaf inner chamber, tentatively realized the function that not only can shield electromagnetic wave but also can shield sound wave, but also there are some shortcomings in this utility model, such as: the sound insulating member that a) needs a kind of ad hoc structure, this sound insulating member complicated structure is difficult for batch production; B) sound insulating member only is arranged in the inner chamber of door leaf, and the sound insulation position is single, so soundproof effect is not ideal enough.
The utility model content
The utility model technical issues that need to address are to provide a kind of sound insulation electromagnetic shield door that not only can shield electromagnetic wave but also can shield sound wave, to overcome the shortcoming that traditional shield door soundproof effect is poor, security performance is not good.
For solving the problems of the technologies described above, technical solution adopted in the utility model is as follows.
A kind of sound insulation electromagnetic shield door comprises the shielding doorframe and the shielding door leaf that are connected through the hinge; The edge of described shielding door leaf is provided with the shielding knife plate, and shielding is provided with on doorframe and shields knife plate equipped shielding cutter groove mutually; Also be provided with the sound partiting system for the shielding sound wave in described shielding door leaf, described sound partiting system comprises that the cross section that is arranged between the shielding cutter groove outside and shielding door leaf is the sound barrier of door type structure, be provided with sound absorber three between the outer face of side of sound barrier and shielding door leaf, be provided with sound absorber two between the U-shaped end of sound barrier and shielding door leaf sidewall extension, be provided with sound absorber one between another of sound barrier side and the inner face that shields door leaf.
Further concrete structure of the present utility model is: be provided with sound absorber four in the inner chamber of described shielding door leaf.
Further concrete structure of the present utility model is: described sound absorber one, sound absorber two, sound absorber three, sound absorber four are composited by multiple-layer absorbers respectively.
Owing to having adopted technique scheme, the technological progress that the utility model is obtained is as follows.
The utility model compact conformation has the double effects that shields electromagnetic wave and sound wave, owing to being provided with sound absorber four in the cavity of shielding door leaf, makes shielding door leaf itself have certain sound insulation capabilities; Owing to all being provided with sound absorber at most of seam crossings of shielding door leaf or the cooperation place of door leaf and doorframe, further strengthened sound insulation capabilities of the present utility model, can effectively prevent the leakage of acoustic information.After tested, in the frequency of utilization scope, the utility model can satisfy the BMB26-2012 standard of National Administration for the Protection of State Secrets.
