In this utility model, when dust needs to be cleaned, the switch door is opened, some cables on the charging control module are pulled out, and then the screws inserted into the bottom plate and the inner wall of the pile body are unscrewed, and finally the charging control module and the bottom plate are pushed out. It is more convenient to move under the action of the guide roller. After the charging control module is removed, the dust inside the pile body can be cleaned, reducing dust accumulation and improving safety. However, in the actual use of this type of charging pile, it is not convenient to change the length of the charging gun cable exposed. Therefore, during use, the middle part of the overlong cable may be rubbed on the ground due to dragging by people, resulting in excessive wear and tear that affects the service life of the cable.

[0004] Therefore, in view of this, research and improvement are conducted on the existing structure and defects, and a charging pile with a cable fixing component is provided. Utility Model Content

[0014] The utility model provides a charging pile provided with a cable fixing assembly, which has the following beneficial effects:

[0015] 1. The utility model sets a wire-reel assembly. After the cable passes through the wire inlet and the wire outlet, the cable will extend from the sliding sleeve to the outside of the protective box. At this time, when the wire reel is rotated, the excess cable can be wound on the outside of the wire reel, which is convenient for storing the cable, avoiding excessively long cables from contacting the ground and preventing wear caused by dragging.

After winding, the positioning plate and the connecting ear can be connected by a pin to fix the cable, preventing the cable from loosening due to accidental rotation of the positioning plate.

[0016] 2. The utility model provides a cleaning component. During the process of winding the cable, since the brush ring is located on one side of the sliding sleeve, the brush on the inner side of the brush ring will pre-clean the outer side of the cable to prevent dust particles from adhering to the outer side of the cable and causing increased wear when in contact with the sliding sleeve. At the same time, during the rotation of the winding reel, the spring will push the piston rod so that the pulley is always in contact with the limit ring. Therefore, the limit ring will drive the piston rod to move up and down reciprocatingly, and when the piston rod moves down, the external air will enter the air cylinder through the first one-way valve, and when the piston rod moves up, the internal air will pass through the second one-way valve and be ejected from the air jet hole in the shunt pipe, so that the dust on the outer side of the cable can be blown off, further improving the cleaning effect.
