Embodiment Construction

[0032] The present invention will be described in more detail below in conjunction with the accompanying drawings.

[0033] Fig. 2 is the slide rail type shielding cabinet of the first specific embodiment of the present invention, which is composed of multiple slide rails and multiple shielding boxes. The shielding box is only big enough to hold a cell phone or other type of communication device. In Fig. 2(a), the slide-rail type shielding cabinet has four slide rails, and there are 3-4 shielding boxes on each slide rail, and the shielding boxes can move freely on the slide rails. In Fig. 2(b), the shielding box is a hexahedron, and a small handle is installed on the opening side for easy opening. The left picture of Figure 2(b) is the opening closed, and the right picture of Figure 2(b) is the opening open. In this embodiment, the shape of the shielding box can also adopt other methods, such as drawer type and so on. In secret-related places such as offices and conference ...

Abstract

The invention provides a fixed visual electromagnetic signal shielding device. According to the technical scheme, the device comprises a shielding box and a movable device. The shielding box has optical perspectivity and electromagnetic signal shielding characteristics. The shielding box is a closed shell with an opening, and the shell is of a two-layer structure attached together. The material ofone layer of structure is a transparent conductive material, and the material of the other layer of structure is a transparent dielectric material. The movable device is a sliding rail, a magnet andthe like. The fixed visual electromagnetic signal shielding device has the characteristics of perspectivity, thin thickness, the small volume and easiness in storage.

Description

technical field [0001] The invention relates to the technical field of office supplies, in particular to a device for shielding intelligent terminal signals. Background technique [0002] In the information age, the confidentiality requirements for specific information within a specific range have gradually become an important compliance. Many industries and units clearly stated that smart electronic devices should not be brought into meeting rooms, offices and other important office places to prevent important information from being illegally stolen through the transmission of wireless electromagnetic signals. [0003] In order to prevent the electromagnetic signals of smart devices such as mobile phones from being illegally intercepted and causing information leakage, many units are equipped with office facilities such as mobile phone storage cabinets. For example, the existing mobile phone storage cabinets are generally hexahedral cabinets made of metal plates, such as ...
