Power adapter convenient to fix

Abstract

The invention discloses a power adapter convenient to fix. The power adapter comprises a shell and a circuit board arranged in the shell; the power adapter is characterized in that the shell comprisesan outer shell and an inner shell; vacuum air suction pumps are arranged on the left side and the right side of the outer shell respectively; an air inlet is formed in one end of the vacuum air suction pump while an air outlet is formed in the other end of the vacuum air suction pump; an adsorption end head with a circular ring structure is arranged on the air inlet, a wire outlet hole is formedin the outer shell; the circuit board is arranged in the inner shell, and a connecting line is arranged on the inner shell; the connecting line extends to the outside of the outer shell from the wireoutlet hole; a connecting block is arranged on the top of the inner shell; the inner shell is fixedly connected with the outer shell through the connecting block; first heat dissipation holes are formed in the bottom of the inner shell; a heat dissipation fan is arranged at the bottom of the outer shell; and second heat dissipation holes are formed in the left side face and the right side face ofthe outer shell. The power adapter has the beneficial effects that the power adapter can be fixedly placed in different environments, so that a situation of accidental falling is prevented; and meanwhile, the heat dissipation performance is high.

Description

technical field [0001] The invention relates to the technical field of power adapters, in particular to a power adapter that is easy to fix. Background technique [0002] The power adapter is a power supply conversion device for small portable electronic devices and electronic appliances. Now when used in some complex environments, the power adapter is often suspended in the air or needs special equipment for prevention and control. Due to the unstable environment of the power adapter, it will Accidental drop will cause some damage to the power adapter. At the same time, the power adapter will generate a lot of heat when it is working. Therefore, the power adapter must have good heat dissipation performance to ensure the normal operation of the power adapter. Contents of the invention [0003] In view of the above disadvantages, the present invention provides a power adapter that is easy to fix outdoors, which can be fixed and placed in different environments to prevent ac...
