[0023] The present invention will now be described in further detail with reference to the accompanying drawings, so that those skilled in the art can implement it based on the description.

[0024] like Figs. 1-3 As shown, this utility model provides a cylindrical anode for chrome-plated piston rods, comprising:

[0025] Anode cylinder 110, connecting plate 120 and two hooks 130.

[0026] The anode cylinder 110 is a cylindrical structure with one open end, and the anode cylinder 110 is a mesh structure made of titanium wire; the connecting plate 120 is a ring structure, and the diameter of the connecting plate 120 is the same as the diameter of the anode cylinder 110, and one end of the connecting plate 120 is connected to the open end of the anode cylinder 110; the hooks 130 are symmetrically arranged on the connecting plate 120.

[0027] In this embodiment, the hook 130 is positioned with the end closest to the connecting plate 120 as the proximal end, and the proximal end of the hook 130 is inclined towards the distal end. That is, the further away the hook 130 is from the connecting plate 120, the larger the distance between the hooks 130, which facilitates the insertion of the piston rod.

[0028] A locking nut 140 is provided at the far end of the hook 130 for fixing the hook 130 to the anode copper plate of the plating tank.

[0029] In this embodiment, the connecting plate is made of titanium.

[0030] The titanium wires of the anode cylinder 110 and the surface of the connecting plate 120 are treated with a special coating.

[0031] In this embodiment, the special coating is lead dioxide, which is used for conductivity and corrosion protection.

[0032] The working process of this utility model is as follows:

[0033] Hook 130 is hung on the anode copper plate of the plating tank, and hook 130 is fastened to the anode copper plate of the plating tank by locking nut 140. After connecting the piston rod to the cathode, the piston rod is placed into the anode cylinder 110, and the piston rod and the anode cylinder 110 are coaxial. The mesh structure of the anode cylinder 110 facilitates the exchange of the plating solution during the chromium plating process.

[0034] The cylindrical anode for chrome-plated piston rods provided by this utility model achieves lightweighting through the mesh-like anode cylinder body. At the same time, it ensures the uniformity of the coating thickness on the piston rod. Furthermore, a special coating treatment is applied to the anode surface to improve corrosion resistance and extend service life.

They can be applied to various fields suitable for this utility model. For those skilled in the art, other modifications can be easily made. Therefore, without departing from the general concept defined by the claims and their equivalents, this utility model is not limited to the specific details and the illustrations shown and described herein.
