Description

Technical Field

[0001] The utility model relates to the technical field of charging pile socket fixing devices, in particular to a fixing device for an AC charging socket of an electric vehicle charging pile. Background Technique

[0002] The charging socket of the charging pile is the interface connecting the vehicle and the charging pile. It is one of the most important accessories of the charging pile. Its function is similar to that of a fuel dispenser in a gas station. It can be fixed on the ground or the wall, installed in public buildings and parking lots or charging stations in residential areas, and can directly connect the input end of electric vehicle charging piles of various models to the AC power grid according to different voltage levels.

[0003] When the existing charging pile sockets are in use, most of them are fixed by fixing bolts to ensure the stability of the sockets. However, in the actual use process, due to the long-term use of the sockets or the influence of environmental factors, the sockets are likely to be damaged or short-circuited. When maintenance and replacement are required, multiple fixing bolts need to be disassembled, which is not convenient for the staff to quickly replace the sockets and affects the normal use of the charging piles. Therefore, a fixing device for the charging socket of an electric vehicle AC charging pile is proposed to solve the above problems. Content of the Utility Model

[0004] The purpose of the utility model is to provide a fixing device for an AC charging socket of an electric vehicle charging pile. Through the slider on one side of the socket body, the slider can be docked with the installation groove and slide, so that the slider slides in the chute, enabling the socket body to be quickly connected to the installation rod. With the use of the operation block, the locking rod moves upward, driving the lifting block to compress the first spring, enabling the socket body to move flexibly, and making the locking rod dock with one of the locking grooves on the positioning rod to quickly lock the socket body, enabling the socket body to be quickly installed, facilitating disassembly, and being convenient for later maintenance and replacement.
