Problems solved by technology

In order to ensure the shielding effect, the shell of the electromagnetic interference shielding device is made of a thicker metal plate. Although the side sliding door with rollers can be installed to a certain extent to facilitate the opening and closing of the door, but because the side sliding door itself Significant, usually it is still necessary to use the electric drive device to assist the opening and closing of the door, which not only increases the equipment cost, but also affects the effect of electromagnetic shielding

Abstract

The invention discloses an electromagnetic interference shielding device, which comprises a metal shielding cover, a side sliding door is installed on the metal shielding cover, a hydraulic tappet is installed between the side sliding door and the metal shielding cover, and the cylinder shaft of the hydraulic tappet Connected to the metal shield, the piston rod is movably inserted into the cylinder, the top of the piston rod is fixedly installed on the handle, and the handle is fixedly installed on the side sliding door; the piston rod is equipped with a piston ring, and the piston ring is connected with the cylinder body. The inner walls are in sealing contact, and the inner wall of the cylinder body is provided with several grooves along the axial direction, and the depth of the grooves gradually decreases from the middle point of the grooves to the two ends of the grooves. The invention can improve the deficiencies of the prior art, and further facilitate the manual operation of the side sliding door of the shielding device under the premise of not using an electric driving device.

Description

technical field [0001] The invention relates to an electromagnetic shielding device, in particular to an electromagnetic interference shielding device. Background technique [0002] With the development of wireless communication technology, the space we live in is full of various electromagnetic waves. Electromagnetic waves have interference effects on the debugging and use of some precision instruments. Moreover, in some secret-related occasions, direct electromagnetic shielding is an important means to ensure safety. In the above scenarios, EMI shielding devices are required. In order to ensure the shielding effect, the shell of the electromagnetic interference shielding device is made of a thicker metal plate. Although the side sliding door with rollers can be installed to a certain extent to facilitate the opening and closing of the door, but because the side sliding door itself Significant, it is usually still necessary to use an electric drive device to assist the o...
