AI Technical Summary

Technical Problem

When the metal parts of the existing test piece holder come into direct contact with the test metal test piece, a galvanic cell will be formed due to the difference in electrode potential, which will accelerate the corrosion of the test piece and make it inconvenient to assemble and install, thus affecting the experimental results.

Method used

The design employs a brass bracket and insulating washers. The combination of brass screws, brass nuts, and insulating washers prevents direct contact between the test piece and metal parts. The insertion ring and notch structure avoids electrode potential differences. Combined with the insulation effect of nylon, rubber, or PTFE washers, the test piece is stably suspended and protected against corrosion.

Benefits of technology

This effectively prevents corrosion of the test piece caused by the formation of a galvanic cell due to the difference in electrode potential, improves the stability and ease of installation of the test piece, and ensures the experimental results.

Abstract

This utility model discloses a specimen assembly rack, including two brass brackets, with a brass screw inserted between the two brass brackets. Both ends of the brass screw are threaded with brass nuts. Multiple specimen bodies can be inserted through the brass screw. A first insulating washer is inserted into one side of each brass bracket, and the first insulating washer is fitted onto the outside of the brass screw. Multiple second insulating washers are snapped onto the outer wall of the brass screw. The bottom of each second insulating washer has a notch, and both ends of each second insulating washer are fixedly connected to insertion rings, which are inserted into through holes. The brass brackets are rectangular in structure, and both ends of the brass screw are fitted with washers. This utility model fixes the brass screw by fitting multiple specimen bodies onto it and then tightening the brass nuts at both ends, thus facilitating the suspension test of the specimen bodies.
