Referring to fig. 1, fig. 2, fig. 4, and fig. 5, a shielding cabinet 200 according to a preferred embodiment of the present invention includes: the cabinet comprises a cabinet body 220 with an opening 221, a cabinet door 210 which is rotatably connected to the cabinet body 220 and used for closing the opening 221, a shielding strip 230 which is arranged between the cabinet door 210 and the cabinet body 220 and surrounds the opening 221, a magnetic force mechanism which is arranged between the cabinet door 210 and the cabinet body 220, and a rotating block 110 which is rotatably connected to the cabinet door 210; when the cabinet door 210 is in a position of closing the opening 221, the magnetic mechanism applies a first acting force to the cabinet body 220 to compress the shielding strip 230; the rotating path of the rotating block 110 is provided with a first position and a second position, and in the process that the rotating block 110 rotates from the first position to the second position, the rotating block 110 can contact with the cabinet 220 and apply a second acting force to the cabinet 220, so as to jack up the cabinet door by the reaction force of the second acting force.

The shielding cabinet in the preferred embodiment of the present invention is a storage cabinet for shielding communication devices such as mobile phones and tablet computers by absorbing and reflecting electromagnetic waves through a shielding body formed by a conductor so that electromagnetic wave signals cannot pass through the shielding body.

The shielding strip is a strip-shaped structure with shielding effect formed by using a conductor.

Wherein, the cabinet door 210 and the cabinet body 220 are rotatably connected through a pivot P2.

When the rotating block 110 is located at the first position and the cabinet door is located at a position for closing the opening 221, a gap exists between the rotating block 110 and the cabinet body 220, and preferably, the rotating block 110 is embedded in the cabinet door 210 at this time; when the rotating block 110 is located at the second position, the distance that the rotating block 110 protrudes from the inner side surface of the cabinet door 210 is greater than the gap between the cabinet door 210 and the cabinet body 220 when the cabinet door 210 is located at the position of closing the opening 221.

When shielding, the cabinet door 210 is in a position closing the opening 221, and electromagnetic wave signals of the communication device stored in the opening 221 are shielded by the conductive cabinet 220, the cabinet door 210 and the shielding strip 230 at the joint of the cabinet 220 and the cabinet door 210, and cannot be transmitted to the outside, and the external electromagnetic wave signals cannot be transmitted into the opening 221.

When the cabinet door is opened, the shielding cabinet 200 in the prior art often needs to apply a large enough acting force to the cabinet door 210 to overcome the first acting force between the cabinet door 210 and the cabinet body 220 due to the existence of the magnetic mechanism, that is, the first acting force needs to be overcome when the cabinet door 210 is opened, which is more laborious; and when the acting force applied by the user is large, the shielding cabinet 200 can even shake, which threatens the safety of the user.
