In the concave groove of described each root support bar, be respectively arranged with plate, described plate along on the length direction of concave groove with scale mark, and by scale value each slot that be arranged in parallel;
Take left side bar, intermediate bar and lower-left bar as a unit, be upright test piece and be inserted on left side bar, intermediate bar and the lower-left bar centerboard in the slot on the corresponding scale value;
Take right-hand rod, intermediate bar and bottom right bar as a unit, be upright test piece and be inserted on right-hand rod, intermediate bar and the bottom right bar centerboard in the slot on the corresponding scale value.
The design feature of experiment device for couple corrosion also is in the utility model soil media: on described left side bar, right-hand rod, lower-left bar and bottom right bar, the trench bottom that is positioned at concave groove arranges fastening bolt, with the position of described fastening bolt fixing insertion in concave groove.
Compared with the prior art, the utility model beneficial effect is embodied in:
1, the utility model is arranged each support bar by " product " type that falls, and utilizes the effective location with graduated plate, can regulate easily and accurately reads the test piece spacing, can also accurately control the position of test piece, guarantees the vertically opposite of test piece plane.
2, the utility model is easy and simple to handle, does not need the processes such as complicated test piece encapsulation and wire be fixing before the test, and test piece that only need to polishing is good is inserted slot and got final product; Directly extract test piece after the off-test from slot, carry out the simple surfaces processing and can calculate weight-loss corrosion speed, the test findings accuracy is high, favorable reproducibility.
3, the utility model experimental enviroment variation is not limited to soil media, can fill other media in apparatus container according to testing requirements and realize galvanizing corrosion test under the varying environment.
Description of drawings
Fig. 1 is the utility model structural representation;
Fig. 2 is the utility model centerboard structural representation;
Number in the figure: 11 left side bars; 12 intermediate bars; 13 right-hand rods; 14 lower-left bars; 15 bottom right bars; 3 fastening bolts; 4 plates; 41 slots; 5 open top containers; 51 panels; 52 backboards.
