Technical Field

[0001] The utility model relates to the technical field of power distribution cabinet production, in particular to an installation device for a wire hole blocking structure of a power distribution cabinet. Background Art

[0002] The wire holes set on the distribution cabinet are used for the entry and exit of cables. In order to ensure the normal entry and exit of cables, the design diameter of conventional wire holes is usually larger than the cable bundle, resulting in gaps after the cables are installed. In daily life, water vapor and small animals may enter, causing the equipment in the cabinet to rust and be damaged, affecting the normal operation of the distribution cabinet.

[0003] The current solution to the above problem is to use a plug structure to seal the wire hole on the distribution cabinet. In order to achieve a good sealing effect, a method of tightening the plug with a reducing structure and the wire hole is generally adopted. However, the current installation of the reducing plug generally relies on manual tightening by personnel. After the equipment has been running for a long time, the plug will loosen and fall off from the wire hole, resulting in sealing failure. Summary of the invention
