Split type shielding case with quick-assembly structure

Abstract

The invention discloses a split type shielding case with a fast-assembly structure, and belongs to the field of electrical equipment, the split type shielding case with the fast-assembly structure comprises an external protective cover and a hidden base, the external protective cover is installed on the outer side of the hidden base, a spiral guide rail is arranged on the inner side of the external protective cover, the spiral guide rail is in a spiral shape, and the outer protective cover is installed on the hidden base. The lowest end of the hidden base is an open end, the uppermost end of the hidden base is a closed end, the outer side of the hidden base is fixedly connected with a spiral guide strip matched with the spiral guide rail, and the hidden base is further provided with a plurality of reinforcing mechanisms matched with the spiral guide rail. The reinforcing mechanism comprises a pushing ring slidably connected to the interior of the spiral guide strip and an elastic power assembly used for driving the pushing ring to move towards the outer side of the hidden base, the external protective cover and the hidden base can be assembled and disassembled easily, the stability is high after assembly, and therefore the working efficiency is greatly improved, and the safety of the hidden base is improved. And the working intensity is reduced, and great convenience is provided for users.

Description

technical field [0001] The invention relates to the field of electric equipment, and more specifically relates to a split-type shielding cover with a quick-installation structure. Background technique [0002] For example, the authorized announcement number is CN108811479B, which discloses a split square shielding cover and its manufacturing method. Although it has good shielding performance, is easy to manufacture, and has a large production capacity, the present invention has very important significance in the field of shielding technology and precision measurement technology. ; [0003] However, since the electrical components shielded by the shielding cover need to be inspected and maintained regularly, and maintenance is also required when a fault occurs, the shielding cover needs to be removed when the electrical components are inspected, maintained and repaired, and the shielding cover must be removed after the maintenance or repair is completed. cover for installati...

AI Technical Summary

Problems solved by technology

[0003] However, since the electrical components shielded by the shielding cover need to be inspected and maintained regularly, and maintenance is also required when a fault occurs, the shielding cover needs to be removed when the electrical components are inspected, maintained and repaired, and the shielding cover must be removed after the maintenance or repair is completed. cover for installation;

[0004] However, in order to ensure the stability after assembly, the existing shielding cover usually has more structures, which makes the assembly and disassembly of the shielding cover more difficult, and the work efficiency is poor, which brings great inconvenience to the user. We propose a split-type shield with a quick-fit structure
