Description

Technical Field

[0001] The utility model belongs to the technical field of electroplating hangers, and in particular relates to a cyclically usable electroplating hanger. Background Art

[0002] Electroplating rack is a common tool used in metal surface treatment process, mainly used to change the appearance and performance of metal products. In the electroplating process, metal ions are deposited on the surface of the workpiece through the action of electric current to form a uniform, dense metal film with specific functions. The basic principle of electroplating rack is to use electrolysis to reduce metal ions into metal deposited on the surface of the workpiece.

[0003] There are many types of electroplating racks, depending on the shape of the parts, the technical requirements of the coating, the electroplating process and the size of the equipment. For example, there are special racks designed and made for a certain part, and there are general racks suitable for a variety of common parts. The form and structure of the general rack should be determined according to the geometric shape of the plated parts, the technical requirements of the coating, the process method and the size of the equipment. Special racks are divided into two types: one is a special rack designed and made for mass production of parts; the other is a special rack designed according to the complex geometry of the parts and special process requirements.

[0004] After each electroplating operation, a large amount of electroplating liquid will inevitably adhere to the surface of the electroplating rack. This residual electroplating liquid not only affects the reuse of the rack, but also requires workers to spend extra time to carefully clean the electroplating liquid during the transportation process. Such a cleaning process not only increases the workload, but also prolongs the overall working time, which leads to a significant reduction in work efficiency. Utility Model Content

[0024] The electroplating hanger composed of the hanger 1, the mounting ring 3 and the grip 2 is made of stainless steel. When in use, the parts are hung on the hanger 1, and after the electroplating is completed, the parts are removed, and then another batch of parts to be electroplated are hung on the hanger 1 for electroplating, thereby realizing the function of recycling;

[0025] A connecting rod 4 is welded to the inner wall of a mounting ring 3 at the lowest end, and the other end of the connecting rod 4 is welded to the outer wall of a docking block 5. An insert block 6 is inserted at the upper end of the docking block 5, and the bottom of the insert block 6 is expanded and inserted between two insert plates 7. A bottom column 8 is fixedly installed at the bottom of the insert plate 7, and the bottom of the bottom column 8 is fixedly installed on the inner wall of a liquid collecting tray 9. The inner diameter of the opening of the liquid collecting tray 9 is larger than the maximum horizontal vertical length of the hanger 1, and the center of the liquid collecting tray 9 is located on the longitudinal vertical line of the center of the three groups of mounting rings 3.

[0026] Preferably, a through hole is formed through the central end of the docking block 5 , an arc-shaped notch 501 is formed on the inner wall of the through hole, and two groups of the arc-shaped notches 501 are symmetrically arranged on the through hole.

[0027] During specific use, the inner size of the through hole matches the maximum diameter of the two plug plates 7 , and the through hole is located at the center end of the docking block 5 .

[0028] Preferably: the bottom of the plug block 6 is fixedly connected with a truncated cone column 601, a threaded structure is provided on the truncated cone column 601, and threaded grooves matching the truncated cone column 601 are provided on the inner walls of the two plug plates 7. The plug plates 7 are made of rubber, and the inner diameter between the two plug plates 7 is smaller than the maximum diameter of the truncated cone column 601.

[0029] During specific use, the insert block 6 forms a threaded connection structure with the two insert plates 7 through the truncated cone column 601 , and under the action of the truncated cone column 601 , the maximum distance between the two insert plates 7 will be expanded after installation.

[0030] Preferably, three arc-shaped convex strips 701 are installed at equal intervals on the outer wall of each plug board 7 . The arc-shaped convex strips 701 are made of flexible rubber material, and the size of the arc-shaped convex strips 701 is adapted to the inner size of the arc-shaped recess 501 .
