Power supply capable of preventing electric shock and short circuit

Abstract

A power supply device capable of preventing electric shock and short circuit comprises a power supply seat and a power supply plug, wherein the power supply plug is matched with the power supply seat, a sliding groove is formed in the power supply seat, a groove opening is formed in a front end of the sliding groove and communicates with the outside, fixed power supply grooves are horizontally and symmetrically formed in a rear end wall of the sliding groove, first power supply elastic sheets are arranged in the fixed power supply grooves, a sliding block is arranged in the sliding groove and can slide forwards and rearwards, a slot with an opening facing a front end is formed in a front end surface of the sliding block, first guide grooves are horizontally and symmetrically formed in the sliding block and are provided with openings facing the slot, second guide grooves are also horizontally and symmetrically formed in the sliding block and are provided with openings deviating from the slot, through grooves are formed between the first guide grooves and the second guide grooves, gears are rotatably arranged in the through grooves, gear rings of the gears are exposed out of the first guide grooves and the second guide grooves, extrusion and push arms are arranged in the first guide grooves in a sliding way, locking arms are arranged in the second guide grooves in a sliding way, and racks are arranged on end surfaces, opposite to each other, of the extrusion and push arms and the locking arms and are engaged with the gear rings of the gears.

Description

technical field [0001] The invention relates to the field of electricity utilization and power supply, in particular to a power supply device for preventing electric shock and short circuit. Background technique [0002] At present, the power supply device is generally composed of a socket and a plug. The socket is generally installed on the wall or the ground. When the socket is plugged into the socket, it is powered on, so as to supply power to the electrical equipment. Although the traditional socket and plug are more convenient to use, in the traditional socket structure, the conductive shrapnel is generally exposed in the socket, and the socket Generally, it is also connected with the outside world. Therefore, it is equivalent to exposing the conductive shrapnel. If a child inserts the metal rod into the jack, it will cause an electric shock accident, accidentally knocking over the water cup or spilling water on it for other reasons. There will be a short circuit in th...

[0002] At present, the power supply device is generally composed of a socket and a plug. The socket is generally installed on the wall or the ground. When the socket is plugged into the socket, it is powered on, so as to supply power to the electrical equipment. Although the traditional socket and plug are more convenient to use, in the traditional socket structure, the conductive shrapnel is generally exposed in the socket, and the socket Generally, it is also connected with the outside world. Therefore, it is equivalent to exposing the conductive shrapnel. If a child inserts the metal rod into the jack, it will cause an electric shock accident, accidentally knocking over the water cup or spilling water on it for other reasons. There will be a short circuit in the socket, so it will have a great impact on the equipment, and some sockets that can close the socket have also appeared recently, but this socket can also make the metal rod energized when the ordinary metal rod is inserted , there are still security risks
