Side plates 10 are fixedly connected to the outer sides of the two bottom plates 15 at the ends.

[0027] like Figure 1 , 2As described above, the supporting plane formed by the cross bar 4 can hold larger items, and the bottom plate 15 located at the bottom of the cross bar 4 and the cross bar 4 can facilitate the inclined placement of items. At the same time, the connection between multiple bottom plates 15 can place smaller items and prevent them from falling from the top of the bottom plate 15.

[0028] A plurality of strip-shaped through grooves 13 are equidistantly formed on the bottom plate 15 and the cross plate 16 , and the strip-shaped through grooves 13 are arranged along the length direction of the cross bar 4 . The two side plates 10 are connected to the support frame 8 through an adjustment mechanism.

[0029] like Figure 2 , 3 As shown, the arrangement of multiple strip-shaped through slots 13 can ensure that the internal mist is fully distributed, thereby ensuring that the object to be tested can be fully exposed to the salt mist environment, thereby ensuring the accuracy of the experimental data.

[0030] Further, the adjustment mechanism includes two U-shaped rods 5, the two U-shaped rods 5 are symmetrically distributed on the top of the support frame 8, and the ends of the U-shaped rods 5 pass through the support frame 8 and are connected to the tops of the two side plates 10;

[0032] like Figure 3 As shown, by pushing the U-shaped rods 5 on both sides to slide up and down, the supporting plane formed by multiple bottom plates 15, cross plates 16 and side plates 10 can be lifted and lowered, so that it can be adjusted according to the volume of the detected object. After the adjustment is completed, the limit plate 19 is moved and the bayonet 18 on one side is connected to the annular groove 17, so that the position of the bottom plate 15 can be fixed. The structure is simple and practical.

[0033] Furthermore, a through hole 20 is provided on the support frame 8, and the vertical rod 14 is arranged to pass through the through hole 20. A sleeve 21 is fixedly connected to the top of the support frame 8, and the end of the U-shaped rod 5 passes through the sleeve 21, thereby ensuring that the U-shaped rod 5 can perform normal lifting and sliding.

[0034] Furthermore, a plurality of limit blocks 12 are fixedly connected to the ends of the support frame 8, and a limit groove 11 is provided on the inner wall of the test box 7. The limit blocks 12 are connected in the limit groove 11, which can limit the position of the support frame 8, thereby improving the stability of the support frame 8 when installed in the test box 7, and also facilitate its removal.

After the adjustment is completed, it can be clamped and fixed by the limit plate 19;

[0043] Salt water is placed in the feeding pipe 27, and the feeding pipe 27 is connected to the test box 7 through a connecting pipe. A control valve is installed on the connecting pipe to control the discharge of salt water into the test box 7. Under the action of the atomizing sheet 26, salt mist can be formed to spray the object to be tested coated with powder coating. The test time can be set by the controller, and the corrosion resistance of the powder coating can be tested. The utility model has a simple structure and is easy to adjust. At the same time, it can effectively avoid the falling of the object to be tested, thereby ensuring the accuracy of the experimental data.
