Charging pile charging wire safety device

Abstract

The invention discloses a charging pile charging wire safety device which comprises a case fixed to the upper side of the ground, a wire cavity is formed in the case, the right side of the wire cavity is connected with an opening leading to the outside, and a worm shaft is rotatably connected into the bottom wall of the wire cavity. Compared with a traditional new energy charging pile, the charging pile charging wire safety device is advantageous in that the charging device can drive the wire wheel to move up and down when the charging wire is pulled out or tightened so as to ensure that the charging wire is not in contact with the inner wall of the opening to protect the surface of the charging wire, and secondly, the charging gun can be manually taken away for charging only when a vehicle is parked on the parking plate, and the charging wire cannot be tightened immediately through the torsion spring after being pulled out; when the charging gun is returned, the wire wheel rotates reversely through the screwed torsion spring so as to automatically tighten the charging wire, and when the charging gun moves to the innermost side, the wire wheel can be clamped so that the wire wheel cannot rotate, and therefore the charging wire in a non-working state is protected from being pulled out intentionally.

Description

technical field [0001] The invention relates to the field of new energy charging piles, in particular to a safety device for charging cables of charging piles. Background technique [0002] With the development of the times, automobiles have been widely used in the lives of residents as a means of transportation. In order to protect the environment, the use of new energy vehicles has gradually increased. The energy supplement of new energy vehicles is mainly completed by charging piles. However, The current charging piles still have certain safety problems. Among them, the charging wires in the charging piles are often pulled out or even damaged due to various reasons. In order to protect the charging wires in the charging piles, it is necessary to Design a charging pile charging line safety device. Contents of the invention [0003] Technical problem: The charging line in the charging pile is often pulled out or even damaged due to various reasons. In order to protect th...
