Safe power supply device

Abstract

The invention provides a safe power supply device which comprises a power supply seat and a power supply head matched with the power supply seat. The power supply seat is internally provided with a positioning groove with an upward opening. Locking grooves are symmetrically arranged in the two side walls of the positioning groove. The bottom of the positioning groove is provided with two power supply grooves in left and right symmetry. The lower end part of the power supply head is provided with a sliding groove with a downward opening. The sliding groove is slidingly equipped with a power transmission sliding block inside. The lower end of the power transmission sliding block is fixedly equipped with two power transmission inserting rods in left and right symmetry. The upper end wall of the sliding groove is provided with two guide grooves in left and right symmetry inside, the two guide grooves communicate with the sliding groove, and each of the guiding grooves is slidingly equipped with a pushing rod inside.

Description

technical field [0001] The invention relates to the field of electric power supply, in particular to a safe power supply device. Background technique [0002] The power supply head and the power supply seat are used together to supply power to the electrical equipment. The traditional power supply head and the power supply seat use the friction between them to realize the locking of the inserted state, but this locking method is extremely unstable. When working in the power supply state of the electrical equipment, if you accidentally touch the plug, it will be easily disconnected from the socket, resulting in a power outage of the electrical equipment, which will easily affect the electrical equipment, and the traditional power supply head is inserted into the power supply socket. Sparks are often seen at the moment, and this kind of spark is easy to cause a fire when it encounters flammable substances. Therefore, there are great safety hazards in the traditional power supp...

[0002] The power supply head and the power supply seat are used together to supply power to the electrical equipment. The traditional power supply head and the power supply seat use the friction between them to realize the locking of the inserted state, but this locking method is extremely unstable. When working in the power supply state of the electrical equipment, if you accidentally touch the plug, it will be easily disconnected from the socket, resulting in a power outage of the electrical equipment, which will easily affect the electrical equipment, and the traditional power supply head is inserted into the power supply socket. Sparks are often seen at the moment, and this kind of spark is easy to cause a fire when it encounters flammable substances. Therefore, there are great safety hazards in the traditional power supply head and power supply seat. They are all fixed and protrude from the power supply head. Therefore, if they are stepped on when not in use, they are easily bent or even broken, which will affect the use
