Control power supply capable of automatically and safely powering off

Abstract

The invention relates to the technical field of power supplies, and discloses a control power supply capable of automatically and safely powering off. The control power supply comprises a base, a machine body, a storage battery and a side door, the bottom of the machine body is fixedly connected with the top of the base, the storage battery is movably installed in the machine body, and the side door is movably connected with the right side of the machine body. And a cavity is formed in the right side of the top of the base, and a rotating gear is movably connected into the cavity. According to the control power supply capable of automatically and safely powering off, when a connector of the storage battery in the device is loosened, a threaded transmission rod can be driven to rotate by rotating an adjusting knob, a threaded ring moves leftwards on the surface of the threaded transmission rod under the action of a thread, and a toothed plate is driven to move leftwards; when the toothed plate moves leftwards, a rotary gear is driven to rotate clockwise, so that the side door rotates rightwards to be opened, the side door achieves the effect of being convenient to open, and the position of the storage battery can be conveniently inserted and fixed again after the side door is opened.

Description

technical field [0001] The invention relates to the technical field of power supplies, in particular to a control power supply that can automatically and safely cut off power. Background technique [0002] An uninterruptible power supply is an uninterruptible power supply that contains an energy storage device. It is mainly used to provide uninterrupted power supply for some devices that require high power stability. When the mains input is normal, the UPS will stabilize the mains and supply it to the load. At this time, the UPS is an AC power supply. At the same time, it also charges the battery in the machine; when the mains power is interrupted, the UPS immediately uses the DC power of the battery to continue to supply 220V AC power to the load through the inverter switching method, so that the load can maintain normal operation and protect the load The software and hardware are not damaged, and UPS equipment usually provides protection for overvoltage or undervoltage. ...

AI Technical Summary

Problems solved by technology

[0003] There is usually a battery inside the uninterruptible power supply. When the device is used for a long time, the terminal part of the battery and the device is prone to loosening, which makes the device unable to supply power. The traditional control power supply is mainly controlled by bolts, etc. The fasteners are fixed together, and it is troublesome to disassemble and assemble. When the joint position of the battery is loose, it is not convenient to plug and fix the joint position again. For this reason, we have proposed a control system that can automatically and safely cut off the power. power supply
