Metal or non-metallic material be made.Can meet the needs of shielded signal or energy, cause the operation lighter weight of door 131 again,
Convenient switch.
In a preferred embodiment, depending on application scenario, portion top wall region can be chosen whether with operation door one
Rise and rotate.Specifically, when operation door 131 is closed to shielding case body 1, rotating shaft side 1311 and the summit of free margins 1312（Top
Summit）Between line 14 can taking human as roof 12 is divided into separable two regions 121,122, operate 131 pairs of door
The region 121 for the roof 12 answered connects as one with operation door 131 and operation door 131 can be followed to rotate.Such structure, can
So that the shielding properties for the test space B that itself is realized is more excellent when being opened by operation door 131.
In a preferred embodiment, operate the base of door 131 and be located at sustained height with the base of side wall 11.By that will operate
131 bases of door and the base of side wall 11 are arranged on sustained height, and the threshold entered inside shielding case body 1, Neng Goufang is just not present
Just experimental facilities is moved to the inside of shielding case body 1 and removes it from the inside of shielding case body 1.
In a preferred embodiment, the bottom of door 131 is at least operated to be provided with beneficial to the more than one of rotating operation door 131
Universal wheel., can be by the strength rolled needed for further saving switching manipulation door 131 by the setting of universal wheel.Certainly, it is
The movement in the whole darkroom of convenience, can be also provided with universal wheel in the other positions of the bottom of shielding case body 1.
In one embodiment, the shielding case body 1 can also include the bottom wall 13 for being arranged at the bottom of side wall 11.By side wall
11 and its roof 12 and bottom wall 13 at both ends enable to the shielding properties of shielding case body 1 more excellent.
In one embodiment, the side wall 11 in shielding case body 1 can be directly constituted by the sheet material of one piece of entirety or
It can also be collectively formed by the single sheet material of polylith, when being assembled into side wall 11 using the single sheet material of polylith, preferably, can pass through
Dismountable mode such as splice, be spirally connected, snapping connection and collectively forming the side wall 11, naturally it is also possible to using non-dismountable mode
Assemble them into one.
In addition, roof 12 and/or bottom wall 13 can also be directly constituted by the sheet material of one piece of entirety or can also be by respectively
The single sheet material of polylith collectively forms, likewise, when being assembled into roof 12 and/or bottom wall 13 using the single sheet material of polylith, it is excellent
Choosing, can be by splicing, being spirally connected, dismountable mode such as snapping connection and collectively form the roof 12 and/or bottom wall 13, certainly
One can be assembled them into using non-dismountable mode.
In use, the anechoic chamber, can be used for indoor far field, Compact Range test and the experiment of outdoor near-field scan.Letter
For wanting：
