[0026] The present invention will be described in further detail below in conjunction with the accompanying drawings so that those skilled in the art can implement the invention with reference to the description.

[0027] like Figure 1 、 Figure 2 As shown, the utility model provides a salt spray test fixture with adjustable sample placement angle, comprising:

[0028] A connecting frame 110, a rotating rod 120 and a sample box 130, one end of the connecting frame 110 can be detachably set on a storage rack in the salt spray test equipment, one end of the rotating rod 120 can be rotatably connected to the other end of the connecting frame 110, and the sample box 130 can be rotatably set at the other end of the rotating rod 120 for placing samples.

[0029] The number of the connecting frames 110 may be one or two.

[0030] In this embodiment, there are two connecting frames 110 , both of which are L-shaped structures, and the two connecting frames 110 are symmetrically and rotatably arranged on both sides of one end of the rotating rod 120 .

[0031] In another embodiment, the number of the connecting frame 110 is one, and the structure of one connecting frame 110 is a U-shaped structure. The bottom of the U-shaped structure is detachably fixed to the storage rack in the salt spray test equipment by bolts, and one end of the rotating rod 120 is rotatably set in the U-shaped structure.

[0032] In this embodiment, a through hole is provided at one end of the rotating rod 120 , and a threaded hole is provided at the other end.

[0033] In this embodiment, threaded holes are provided at both ends of the two connecting frames 110 .

[0034] A first connecting pin (not shown in the figure) is provided between the threaded hole at the other end of the two connecting frames 110 and the through hole at one end of the rotating rod 120, and the first connecting pin and the two connecting frames 110 are threadedly matched. The rotation of the rotating rod 120 relative to the two connecting frames 110 is achieved by adjusting the tightness between the first connecting pin and the two connecting frames 110.

[0035] In another embodiment, threaded holes are provided at both ends of the U-shaped structure of one connecting frame 110 , and the specific connection relationship between the connecting frame 110 and the first connecting pin is the same as the connection relationship between the two connecting frames 110 and the first connecting pin.

[0036] like Figure 3 As shown, the sample box 130 is a box-shaped structure with an open top and a mesh structure 140 at the bottom. The bottom of the sample box 130 is an inclined structure and the top is a flat surface, which facilitates the outflow of salt mist after condensation into liquid after the sample is placed.

[0037] A through hole is provided on one side of the sample box 130 , and the height of one side of the sample disc is higher than the height of the other side of the sample disc.

[0038] A second connecting pin (not shown) is provided between the through hole of the sample box 130 and the other end of the rotating rod 120, and the second connecting pin and the rotating rod 120 are threadedly engaged. By adjusting the tightness between the second connecting pin and the rotating rod 120, the sample box 130 can be rotated relative to the rotating rod 120, thereby realizing the secondary rotation structure of the sample box 130.

[0039] The working process of this utility model is:

[0040] The two connecting frames 110, the rotating rod 120, and the sample box 130 are completely connected by the first connecting pin and the second connecting pin. The other ends of the two connecting frames 110 are pre-fixed to one end of the rotating rod 120 by the first connecting pin. Then, one end of each of the two connecting frames 110 is fixed to the storage rack in the salt spray test equipment by bolts. The first connecting pin is tightened, and the sample is placed in the sample box 130. The required test angle of the sample is adjusted and the salt spray test is started. At this time, the salt water condensed on the surface of the sample is guided through the screen and the inclined structure of the sample box 130.

[0041] The utility model provides a salt spray test fixture with adjustable sample placement angle. Through the combination of a connecting frame, a rotating rod and a sample box, the sample can be placed at multiple angles. Each structure is detachable, which is convenient for replacement and reduces costs. In addition, the sample box has an inclined structure and a mesh structure at the bottom, which improves stability and conductivity.

[0042] Although the embodiments of the present invention have been disclosed above, they are not limited to the applications listed in the description and implementation methods. They can be fully applied to various fields suitable for the present invention. For those familiar with this field, additional modifications can be easily implemented.
