Summary of the invention
The purpose of this utility model is to provide a kind of fixture that is applied to electro-chemical test, has solved the working electrode existing in prior art and has made flow process complexity, and the cycle is long, not easy-operating problem.
For realizing the utility model object, adopt following technical scheme:
Be applied to a fixture for electro-chemical test, comprise clamp body, set bolt and copper coin; Described clamp body is rectangular structure, from the upper surface of rectangular parallelepiped, has vertically downward sample cell, from the front end face of rectangular parallelepiped, is provided with taper instrument connection, and taper instrument connection is communicated with sample cell; From the rear end face of rectangular parallelepiped, to sample cell, be provided with threaded hole, set bolt is connected with threaded hole, is provided with successively from front to back test sample and copper coin in sample cell.
For further realizing the purpose of this utility model, preferably, the upper conical instrument connection upside of the front end face of described rectangular parallelepiped has exhaust groove.
The area of described taper instrument connection and sample cell junction is 1 square centimeter.
Described clamp body is made by teflon.
With respect to prior art, tool of the present utility model has the following advantages:
1, the utility model is without the special working electrode of making.During test, only sample need be clipped to test with fixture, without sample is cut, welding lead, the manufacturing process such as resin solidification encapsulation.
2, the utility model is simple to operate.Deducted the complicated manufacturing process of working electrode.
Accompanying drawing explanation
Fig. 1 is the structural representation that the utility model is applied to the fixture of electro-chemical test;
Fig. 2 is application the utility model fixture test schematic diagram;
Shown in figure: set bolt 1, clamp body 2, copper coin 3, test sample 4, exhaust groove 5, taper instrument connection 6, sample cell 7, beaker 8, test solution 9, to electrode 10 and contrast electrode 11.
