This utility model belongs to the field of charging pile technology, and in particular relates to a charging pile cable telescopic device, including a charging pile body. A charging gun is hung on the outer wall of the front middle part of the charging pile body, and a cable is fixedly connected to the bottom end of the charging gun. A positioning component is installed on the outer wall of the bottom right side of the charging pile body. A winding shaft is mounted on the inner wall of the bottom end of the charging pile body with a bearing. A first gear is fixedly sleeved on the outer side of one end of the winding shaft, and a reinforcing bracket is sleeved on the outer side of the other end of the winding shaft with a bearing. The bottom end of the reinforcing bracket is fixedly connected to the charging pile body. Multiple sets of auxiliary rotation components are arranged in a ring on the outer side of the first gear. Two limiting discs are symmetrically fixedly sleeved on the outer side of the middle part of the winding shaft. A second directional gear is welded and fixed to the right end of the winding shaft. This utility model can avoid tension on the cable during charging and facilitates a stable connection between the charging gun and the vehicle charging port.

This invention belongs to the field of textile fabric processing technology, specifically a surface coating device for waterproof fabric processing. Addressing the problem that existing waterproof fabrics lack anchoring points between the waterproof coating and the yarn layer for reinforcement, the following solution is proposed: a main unit housing with a sealed partition bolted to its bottom inner wall. A coating chamber is located at one end of the main unit housing near the partition, and a drying chamber is located at the other end. A feed roller is fixed at one end between the inner walls of both sides of the main unit housing. This invention uses an external air pump to inflate the air inlet ring and blows air through an air guide pipe into the injection hole on the injection head. The negative pressure forces the waterproof coating into the interior of the fabric body through the feed hole on one side, coating and injecting the waterproof fabric into its interior. After solidification with the surface waterproof fabric, it forms a deep cone, improving the tensile and waterproof resistance of the finished fabric.
