AI Technical Summary

Technical Problem

Existing power extension cord covers are prone to short circuits in humid environments, lack effective locking mechanisms, have low safety, and poor installation flexibility.

Method used

A power extension cord with a protective cover was designed. The protective cover is connected by a circumferential hinge, equipped with a locking block and a lock hole platform. The protective cover can be opened and closed quickly by pressing mechanism, and a compression spring is used to provide the rebound force. Combined with the design of the lifting hole and the winding plate, the installation flexibility and safety are improved.

Benefits of technology

It prevents short circuits in humid environments, improves safety, prevents children from accidentally touching it, and enhances the flexibility and safety of installation.
