AC-DC dual power supply with good protection performance

Abstract

The invention discloses an AC-DC dual power supply with good protection performance, which comprises a power supply body, wherein support plates are fixedly connected to the bottom parts of the two sides of the power supply body, a protection shell is slidably connected to the top parts of the support plates, the power supply body is located in the protection shell, supporting blocks are fixedly connected to the two sides of the top part of each support plate, the inner sides of the supporting blocks are slidably connected with the surface of the protective shell, positioning blocks are arranged at the top parts of the supporting blocks, the bottom parts of the positioning blocks penetrate to the bottom parts of the supporting blocks, the top part of the protective shell communicates with a frame, and fans are transversely and fixedly connected to the front side and the rear side in the frame. The AC-DC dual power supply with good protection performance solves the problems that an existing AC-DC dual power supply cannot be protected in the use process of the AC-DC dual power supply, and the AC-DC dual power supply is damaged and cannot operate due to extrusion of external force; and the disclosed AC-DC dual power supply has the advantage of good protection performance, and the practicability of the AC-DC dual power supply is improved.
