The adjustment part can adjust the curvature of the bent part of the cooling pipe 1 and ensure that the cooling pipe 1 will not be excessively bent. A coolant is flowed in the cooling pipe 1 in the present embodiment, and the heat generated when the cable is working is taken away by the coolant.

[0022] Reference Figure 2 and 3 The adjustment part in this embodiment realizes the adjustment function by a plurality of parts, including a second connecting piece 9, which is fixed on the shell 5. A flexible joint 13 is sleeved on the cooling pipe 1, which can be constrained by a bellows. The pipe body of the cooling pipe 1 on both sides of the flexible joint 13 is fixed to the second connecting piece 9 by a clamp 11, wherein the flexible joint 13 is connected to the second connecting piece 9 by a second locking piece 12. In this embodiment, a U-shaped pipe clamp is used to constrain the cooling pipe 1, and threads are provided at both ends of the U-shaped pipe clamp. Two through holes are provided on the second connecting piece 9. The threaded section of the U-shaped pipe clamp passes through the through hole and is fixed by a nut to limit the spacing between the cooling pipe 1 and the second connecting piece 9, thereby realizing the adjustment of the bending curvature of the second connecting piece 9.

[0023] In some embodiments, the structure of the adjustment part is optimized, and a first sleeve and a second sleeve are designed. A flexible joint 13 (corrugated tube) is installed between the first sleeve and the second sleeve. The cooling pipe 1 passes through the first sleeve and the second sleeve and the flexible joint 13. Threaded seats are installed on the first sleeve and the second sleeve. A double-threaded screw is threadedly installed between the two threaded seats. The double-threaded screw is rotated to adjust the curvature between the first sleeve and the second sleeve. The installer can quickly and synchronously adjust the angle between the first sleeve and the second sleeve by rotating the double-threaded screw. The adjustment accuracy is higher. In actual production, a buckle is installed on the double-threaded screw, and a slot is provided on the second connecting member 9 for fixing the double-threaded screw and the adjustment part.

[0024] Continue to observe the attached Figure 1In this embodiment, a flange is provided on the side edge of the opening of the shell 5, and a sealing member 7 is sleeved on the flange. The sealing member 7 here uses a rubber ring. When the wire-passing device is installed, the shell 5 is fixed to the charging pile cabinet using a first fixing member 8. The first fixing member 8 here is an M6×20 bolt; in addition, two first connecting members 4 are staggeredly installed on the opening side of the shell 5, and the positive electrode sheet 2 and the negative electrode sheet 3 are fixedly connected to the corresponding first connecting member 4 by bolts. The staggered arrangement of the two electrode sheets can facilitate the connection of the power source body.

[0026] In specific use, when installing the cooling pipe 1, first, the flexible joint 13 is sleeved on the two cooling pipes, and the cooling pipe is fixed on the second connecting piece 9. The second connecting piece 9 itself has a movable angle. The threaded section of the second locking piece 12 (U-shaped pipe clamp) passes through the through hole on the second connecting piece 9 and is fixed by the second fixing piece 10 (nut), which limits the distance between the cooling pipe 1 and the second connecting piece 9, thereby realizing the adjustment of the bending curvature of the second connecting piece 9, ensuring stable installation, preventing excessive bending during the installation of the cooling pipe 1, and ensuring the heat dissipation of the charging pile cable.
