A waterproof and electric shock-proof power adapter

Abstract

The invention discloses a waterproof and electric shock-proof power adapter, which comprises a sealed casing, a fixed top plate and a fixed bottom plate, the fixed bottom plate is fixedly installed on the outer surface of the lower end of the sealed casing, two groups of docking plugs are movably installed under the fixed bottom plate, A second turntable is movably installed on the inner side of the upper end of the fixed base plate, and two groups of first turntables are movably installed on the inner inner surface of the second turntable, and the docking plug and the second turntable are movably connected through the first turntable, so Both the inner surfaces of the fixed bottom plate and the second turntable are provided with circular slots, the fixed top plate is fixedly installed on the inner surface of the upper end of the sealed casing, and the inner inner surface of the fixed top plate is movably installed with a side-rotating card cover; so that The waterproof and electric-shock-proof power adapter has a double-rotating adjustment structure, which improves its flexibility in use, and at the same time makes it have a sealed and closed structure, which improves its waterproof and dustproof effect and prolongs its service life.

Description

technical field [0001] The invention belongs to the technical field of power adapters, in particular to a waterproof and electric shock-proof power adapter. Background technique [0002] The power adapter, also known as an external power supply, is a power supply voltage conversion device for small portable electronic equipment and electronic appliances. [0003] A power adapter disclosed in the reference document CN203909712U includes: an outer shell, an inner shell, a base and a power adapter circuit, the inner shell is set inside the outer shell, the base is set at the lower end of the inner shell, and the power supply The adapter circuit is arranged on the base, a heat dissipation fan is provided on the wall at one end of the inner shell, and an exhaust hole is arranged on the wall at the other end of the inner shell, and the heat dissipation fan is relatively parallel to the exhaust hole It is provided that the housing wall on the same side of the outer shell and the i...

Problems solved by technology

[0005] In order to overcome the traditional waterproof and electric shock-proof power adapter, the joint is designed with a fixed structure, so that the traditional power adapter can only be installed in the slot of a fixed model. When the space in the slot is not enough, the traditional power adapter cannot be installed. The use reduces the flexibility of its use; at the same time, the traditional power adapter does not have a sealed and waterproof structure, which makes the power adapter vulnerable to external factors and causes water short-circuits, which reduces the safety of the power adapter when it is used; secondly, the traditional power adapter The adapter does not have an auxiliary fixing structure, so that the power adapter is prone to breakage at the line body joint during long-term use, which reduces the service life of the power adapter, and a waterproof and electric shock-proof power adapter is provided
