After the sealing is completed, salt water is injected into the box body 1 and heated by the electric heater in the box body 1 to evaporate the salt water and generate water vapor. The water vapor forms an air flow through the heater and is mixed with air in the test chamber after being adjusted by the air flow regulator to form a saturated salt spray environment for salt spray testing of the sample to be tested. After the test is completed, the box cover 2 is opened and the rotating frame 4 is rotated to make the right end of the rotating frame 4 tilt upward, so that multiple samples to be tested placed in the V-shaped placing strip 5 can be discharged uniformly through the discharge opening 3. The operation is simple and very efficient, which is beneficial to improving the test efficiency.

[0024] Embodiment 2:

[0025] Please refer to Figures 1-6As shown in the figure, on the basis of the first embodiment, the present utility model provides a technical solution: at the four corners of the bottom of the box body 1, there are fixedly connected with supporting feet 11. At the bottom of the box body 1, there is fixedly connected with a fixed frame 12. The fixed frame 12 is located inside the supporting feet 11. The inner wall of the fixed frame 12 is slidably connected with a limiting frame 19. At the bottom of the limiting frame 19, there is provided a universal wheel 20. The universal wheel 20 is located outside the supporting feet 11;

[0026] On the bottom of the box body 1, there is provided a circular groove 14. The inner wall of the circular groove 14 is fixedly connected with a hydraulic cylinder 15. The output end of the hydraulic cylinder 15 is fixedly connected with a purlin 16. The front and rear ends of the purlin 16 are fixedly connected with the inner wall of the limiting frame 19;

[0027] In this implementation scheme, when it is necessary to move the test box, start the hydraulic cylinder 15 to push the limiting frame 19 to move downward, so that the universal wheel 20 extends out of the supporting feet 11, and drive the test box to move through the universal wheel 20. When it is not necessary to move the test box, drive the limiting frame 19 to move upward through the hydraulic cylinder 15, retract the universal wheel 20 inside the supporting feet 11, and the stable supporting effect can be achieved through the supporting feet 11. At the same time, the supporting feet 11 can protect the universal wheel 20;

[0028] On the purlin 16, there are provided clamping holes 17. A cross bar 18 is inserted through the clamping holes 17. The top surface of the cross bar 18 is fixedly connected with the bottom surface of the limiting frame 19. Symmetrically on the inner wall of the fixed frame 12, there are provided grooves 13. The outer wall of the cross bar 18 is slidably connected with the inner wall of the grooves 13;

[0029] At the bottom of the box body 1, there is fixedly connected with a telescopic rod 21. The end of the telescopic rod 21 far away from the box body 1 is fixedly connected with the top surface of the cross bar 18. At the bottom surface of the box body 1, there is fixedly connected with a spring 22. The spring 22 is located outside the telescopic rod 21. The bottom end of the spring 22 is fixedly connected with the top surface of the cross bar 18;

[0030] In this implementation scheme, the cross bar 18 and the purlin 16 are cross - arranged and are both connected with the limiting frame 19, which improves the supporting strength of the limiting frame 19. At the same time, between the box body 1 and the cross bar 18, the limiting and buffering effect is realized through the telescopic rod 21 and the spring 22, making the process of the up - and - down movement of the universal wheel 20 more stable and safe.

[0031] Working principle: During the test, place the sample to be tested on the V-shaped placing strip 5, then close the box cover 2. The sealing rubber strip 9 and the baffle 10 on the box cover 2 are used to seal the gap 8 and the discharge port 3 of the box body 1 respectively. After the sealing is completed, inject brine into the box body 1 and heat it through the electric heater in the box body 1 to evaporate the brine and generate water vapor. The water vapor forms an air flow through the heater and mixes with the air in the test chamber after being adjusted by the air flow regulator to form a saturated salt mist environment for salt spray testing of the sample to be tested. After the test is completed, open the box cover 2 and rotate the rotating frame 4 to make the right end of the rotating frame 4 tilt upward, and then the multiple samples to be tested placed in the V-shaped placing strip 5 can be discharged uniformly through the discharge port 3. When it is necessary to move the test chamber, start the hydraulic cylinder 15 to push the limit frame 19 downward to make the universal wheels 20 extend out of the support feet 11, and drive the test chamber to move through the universal wheels 20. When it is not necessary to move the test chamber, retract the universal wheels 20 inside the support feet 11, and the support feet 11 can achieve the effect of stable support, and at the same time, the universal wheels 20 can be protected by the support feet 11.
