Abstract
The utility model discloses a sound insulation shielding door of a sound reducing box. The sound insulation shielding door is characterized by comprising a sound insulation part and a shielding part, wherein the sound insulation part is provided with a rubber strip; and the shielding part is provided with a good conductor. When the sound insulation shielding door is closed, the rubber strip of the sound insulation part and the good conductor of the shielding part are both tightly clung onto a box body of the sound reducing box, so that a good sound insulation effect can be guaranteed and an effective RF (Radio Frequency) signal shielding effect can be achieved at the same time.
Description
Technical field
The utility model relates to a kind of soundproof shielding case door of Sound Attenuator.
Background technology
In the acoustical behavior test process of communication or other electronic products (such as mobile phone), need simultaneously isolating exterior RF radiofrequency signal.
And the acoustic measurement environment such as general Sound Attenuator or sound attenuation room, in order to reach good isolates sound effect, its soundproof door need to adopt the soft insulating material such as rubber to design, because rubber is soft material, when door is closed, can cause it that deformation occurs, thereby guarantee the very sealing that door can close; And the RF radio shielding needs Sound Attenuator to have the casing that a complete good conductor consists of, namely without slit or the hole of any insulation.In door design, also be conductor when just needing door to close and the contacting of conductor.And the setting of the soft material such as above-mentioned rubber has caused whole Sound Attenuator can't form a complete good conductor seal case at door and other interfaces, thereby can not effectively shield the RF radiofrequency signal.
The utility model content
The purpose of this utility model is for defects of the prior art, and a kind of soundproof shielding case door of improved Sound Attenuator is provided, and it can guarantee good soundproof effect, also can realize good RF radio frequency signal shield effect simultaneously.
For realizing above-mentioned utility model purpose, the utility model has adopted following technical scheme: a kind of soundproof shielding case door of Sound Attenuator, described Sound Attenuator comprises casing, it is characterized in that: described soundproof shielding case door comprises sound proof part and shielding part, described sound proof part is provided with rubber strip, described shielding part is provided with good conductor, and when described soundproof shielding case door was closed, the rubber strip of described sound proof part and the good conductor of described shielding part all fitted tightly on the casing of described Sound Attenuator.
In addition, the utility model also provides following attached technical scheme:
Described sound proof part is near the inboard of described casing, and described shielding part is near the outside of described casing.
Described rubber strip is arranged on the upper/lower terminal of described sound proof part.
Described good conductor is arranged on the upper/lower terminal of described shielding part.
Described good conductor is that metal material of copper is made.
The soundproof shielding case door inside of described Sound Attenuator is filled with sound insulation materials.
The soundproof shielding case of described Sound Attenuator outdoors wall is provided with handle.
Than prior art, the utility model has the advantage of: the soundproof shielding case door of Sound Attenuator of the present utility model, by at the soundproof shielding case door sound proof part and shielding part being set, and rubber strip and good conductor be installed respectively, thereby can guarantee good soundproof effect, also can realize preferably RF radio frequency signal shield effect simultaneously.
Description of drawings
Fig. 1 is the floor map corresponding to the Sound Attenuator of the utility model preferred embodiment and soundproof shielding case door thereof.
The specific embodiment
Below in conjunction with preferred embodiment and accompanying drawing thereof technical solutions of the utility model are done further nonrestrictive detailed description.
With reference to Fig. 1, a kind of soundproof shielding case door of Sound Attenuator, described soundproof shielding case door 6 comprises sound proof part 1 and shielding part 2, described sound proof part 1 is provided with rubber strip 3, described shielding part 2 is provided with good conductor 4, when described soundproof shielding case door 6 was closed, the rubber strip 3 of described sound proof part 1 all fitted tightly on the casing 7 of described Sound Attenuator with the good conductor 4 of described shielding part 2.The outer wall of described soundproof shielding case door 6 is provided with handle 9, and is rotated by the loose-leaf 8 that is installed in its lower end, outside.
In addition, described sound proof part 1 is near the inboard of described casing 7, and described shielding part 2 is near the outside of described casing 7.
Described rubber strip 3 is arranged on the upper/lower terminal of described sound proof part 1.
Described good conductor 4 is made by metal material of copper, and be mounted on the upper/lower terminal of described shielding part 2, contact with casing by this good conductor, thereby Sound Attenuator is formed contacting of complete conductor and conductor, can effectively shield the RF radiofrequency signal like this.
In addition, soundproof shielding case door 6 inside of described Sound Attenuator are filled with sound insulation materials.
Than prior art, the soundproof shielding case door of Sound Attenuator of the present utility model by at the soundproof shielding case door sound proof part and shielding part being set, and is installed respectively rubber strip and good conductor, thereby can guarantee good soundproof effect, also can realize effective RF radio frequency signal shield effect simultaneously.
It is to be noted; above-mentioned preferred embodiment only is explanation technical conceive of the present utility model and characteristics; its purpose is to allow the personage who is familiar with technique can understand content of the present utility model and according to this enforcement, can not limit protection domain of the present utility model with this.All equivalences of doing according to the utility model Spirit Essence change or modify, and all should be encompassed within the protection domain of the present utility model.
