[0147] The pitch-type folding door 16 is closed, and the folding shaft 32 drives the shielding cloth winding shaft 64 to rotate through the pulley 65 and the transmission belt, and the shielding cloth winding shaft 64 releases the winding of the shielding cloth. At this time, under the action of the reset shaft returning to its original position, the rope winding wheel 66 pulls the shielding cloth 68 through the pull rope 67 to pass through the pressing plate 49 and the supporting plate 45, and the shielding cloth and the shielding plate 63 complete the shielding of the test product fixture in the five directions of bottom, left, right, front and back, thereby enclosing the test product fixture therein, and the shielding cloth 68 is fixed between the pressing plate 49 and the supporting plate 45. After the test is completed, the pitch-type folding door 16 is opened, the antenna transmitting unit 19 releases the limit on the test product fixture, and the transverse motor works, thereby driving the T-shaped slider to press the pressing rod 56, the second spring contracts, the pressing rod 56 is sent into the limiting sleeve 51, and the vent 58 and the vent The tube 57 is connected, and the gas is sent into the two limit sleeves 51 through the vent port 58, the vent pipe 57, and the connecting pipe 55. The limit sleeve 51 returns to normal pressure, and the first spring 53 drives the first wedge block 52 to return to the limit sleeve 51. The first wedge block 52 releases the limit on the second wedge block 10, and the gas flows back to the lifting sleeve 42 from the air inlet pipe 54. At this time, under the return action of the lifting spring 47, the bearing plate 45 is lifted, and the pressing plate 49 and the bearing plate 45 release the pressure on the shielding cloth 68. The folding shaft 32 is reversed to drive the pitch folding door 16 to open, and the folding shaft 32 drives the shielding cloth winding shaft 64 to cover the shielding cloth 68 through the pulley 65 and the transmission belt. At this time, the test product fixture is reopened near the end of the door body 31, which is convenient for the grabbing material mechanism 13 to move the test product fixture out of the shielding cabin 12.

[0148] In an embodiment provided by the present invention, the pressing plate 49 is provided with an oblique opening near the end of the shielding cloth winding shaft 64 to facilitate the shielding cloth 68 to move near the end of the pull rope 67 .

[0149] The beneficial effects of the above technical solution are:

[0150] The setting of the oblique opening makes it easier for the shielding cloth 68 to be fed between the pressing plate 49 and the carrying plate 45 .

[0151] In one embodiment provided by the present invention, a window is installed on the vertical section of the door body 31.

[0152] Obviously, the above embodiments are merely examples for the purpose of clear explanation, and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived therefrom are still within the scope of protection of the invention.
