[0028] As Figure 4 shown, a clamping groove 13 is formed in the test box 1, the lower end of the sealing cover 3 is clamped into the clamping groove 13, and a sealing gasket is arranged at the position where the sealing cover 3 is connected with the clamping groove 13, so that the sealing property of the connection is improved, and the leakage of salt mist is avoided.
[0029] The principle of the utility model
[0030] As Figure 4 shown, since the placing rack 6 is located in the sealing cover 3, before using the application, the test sample needs to be placed on the placing rack 6 of the sealing cover 3, and then the sealing cover 3 is connected with the test box 1. The specific operation is as follows: the test sample is directly placed on the placing rack 6, the electric telescopic rod 9 is started, the placing rack 6 and the sample are lifted by the lifting plate 8 and the connecting rod 7, until the sample on the placing rack 6 contacts with the fixed frame 15, at this time, the fixed frame 15 can fix the sample, so that the sample does not fall off the placing rack 6 when the sealing cover 3 is installed. Then the sealing cover 3 is installed on the test box 1 by using the clamping groove 13.
[0031] After the sealing cover 3 is installed, the electric telescopic rod 9 is started, the placing rack 6 and the sample are moved downward, so that the sample is separated from the fixed frame 15, and the contact area of the sample and the salt mist is not affected during the salt mist corrosion test. The salt mist is introduced into the sealing cover 3 by using the salt mist nozzle 5, so that the sample is uniformly corroded by the salt mist. Although the setting of the air permeable groove 10 can increase the contact area of the salt mist and the sample, there are still parts on the placing rack 6 that contact the sample, and these parts cannot fully contact the salt mist during the entire corrosion test if not adjusted. For the application, the electric telescopic rod 9 is started, the placing rack 6 and the sample are moved downward, until the supporting plate 11 passes through the air permeable groove 10, at this time, the placing rack 6 is sleeved on the supporting plate 11, and at this time, the structure supporting the sample is changed from the placing rack 6 to the supporting plate 11, and since the supporting plate 11 corresponds to the air permeable groove 10, the parts of the sample that always contact the placing rack 6 can be exposed to the corrosion of the salt mist, so that the effect of completely corroding the sample is improved.
[0032] The above has described the utility model and its implementation mode, which is not restrictive, and the drawings only show one of the implementation modes of the utility model, and the actual structure is not limited thereto. In summary, if a person skilled in the art is inspired thereby, without departing from the creative purpose of the utility model, similar structural modes and embodiments are not creatively designed, which should belong to the protection scope of the utility model.
