However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments of the following disclosure.

[0022] Example 1: Figure 1 - Figure 5 As shown, the utility model provides a salt spray test auxiliary fixture, including a base 1, two fixed blocks 2 are fixedly connected to the inner side of the base 1, one side of the two fixed blocks 2 is rotatably connected to two rotating shafts 3, the outer surfaces of the two rotating shafts 3 are fixedly sleeved with two storage brackets 4, one side of one storage bracket 4 is provided with a plurality of first limiting holes 5, one side of one of the fixed blocks 2 is provided with a second limiting hole 6, one side of the base 1 is provided with a fixing mechanism 7, the opposite side of the two storage brackets 4 is fixedly connected with a slot frame 8, one side of the two storage brackets 4 is provided with two sliding grooves 9, two sliding blocks 10 are slidably connected in the two sliding grooves 9, the opposite side of the two sliding blocks 10 is fixedly connected with a supporting block 11, the opposite side of the two storage brackets 4 is fixedly connected with a fixing plate 12, one side of the fixing plate 12 is threadedly connected with a screw 13, one end of the screw 13 is movably connected with a movable sleeve 14, and the movable sleeve 14 is fixedly connected to one side of the supporting block 11.

[0023] The effect achieved by the entire Embodiment 1 is that by rotating the screw 13, under the action of the thread, the screw 13 drives the movable sleeve 14 to move, the movable sleeve 14 drives the support block 11 to move, and the support block 11 drives the slider 10 to slide synchronously in the chute 9. The distance between the support block 11 and the trough frame 8 is adjusted according to the length of the test sample. After the adjustment is completed, the test sample can be placed on the trough frame 8 and made to lean against the support block 11, which is convenient for placing test samples of different lengths, improves the scope of application, and is easy to operate.

[0024] Embodiment 2: As Figure 1 - Figure 5 shown, the fixing mechanism 7 includes a fixing frame 701 which is fixedly connected to one side of the base 1. A limiting groove 702 is formed inside the fixing frame 701. A limiting block 703 is slidably connected in the limiting groove 702. One side of the limiting block 703 is fixedly connected to a connecting plate 704. One side of the connecting plate 704 is fixedly connected to a limiting rod 705. The other side of the connecting plate 704 is fixedly connected to a pull rod 706. One end of the pull rod 706 movably penetrates through the fixing frame 701. One end of the pull rod 706 is fixedly connected to a pull ring 707. A return spring 708 is sleeved on the outer surface of the pull rod 706. One end of one of the rotating shafts 3 movably penetrates through the other fixing block 2. A scale disk 15 is arranged on one side of the other fixing block 2, and the scale disk 15 is sleeved on the outer surface of one of the rotating shafts 3. A pointer 16 is fixedly connected to the outer surface of one of the rotating shafts 3. A positioning groove 17 is formed on one side of the support block 11. A liquid discharge hole 18 is formed at the bottom of the trough frame 8. The base 1 is of an H-shaped structure, and the trough frame 8 is of a V-shaped structure. A through hole 19 is formed at the top of the base 1. A rotating handle 20 is installed at one end of the screw 13.

[0025] The effect achieved by the entire Embodiment 2 is as follows: By means of the fixed mechanism 7, pulling the pull ring 707 causes the pull ring 707 to drive the pull rod 706 to move. The pull rod 706 drives the connecting plate 704 to move, and the connecting plate 704 drives the limiting block 703 to slide synchronously within the limiting groove 702. As a result, the connecting plate 704 drives the limiting rod 705 to move and separate from the first limiting hole 5 and the second limiting hole 6. At the same time, the return spring 708 is compressed and begins to contract. Then, by rotating the storage bracket 4 under the action of the rotating shaft 3, the angle of the storage bracket 4 is adjusted. After adjusting to the appropriate angle, the pull ring 707 is released. Under the elastic force of the return spring 708, the connecting plate 704 drives the limiting rod 705 to be inserted into the corresponding first limiting hole 5 and the second limiting hole 6, thereby limiting and fixing the storage bracket 4, which facilitates adjusting the inclination angle of the storage bracket 4. Since in the salt spray test chamber, the salt spray is sprayed from above, by adjusting the inclination angle of the storage bracket 4, it is convenient for the test sample and the salt spray to come into full contact. During the process of adjusting the angle of the storage bracket 4, one of the rotating shafts 3 drives the pointer 16 to rotate. By observing the reading of the cooperation between the pointer 16 and the scale disk 15, it is convenient to determine the inclination angle of the storage bracket 4. Additionally, through the provided positioning groove 17, it is convenient to limit the test sample to prevent tilting. The provided drain hole 18 facilitates the drainage of liquid through the drain hole 18, avoiding liquid accumulation in the trough rack 8. The provided through hole 19 facilitates the drainage of liquid through the through hole 19, and the provided turning handle 20 facilitates the rotation of the screw rod 13, increasing the convenience.

[0026] Working principle: First, rotate the turning handle 20, so that the turning handle 20 drives the screw rod 13 to rotate. Under the action of the thread, the screw rod 13 drives the movable sleeve 14 to move. The movable sleeve 14 drives the support block 11 to move. The support block 11 drives the slider 10 to slide synchronously in the chute 9. Adjust the distance between the support block 11 and the groove frame 8 according to the length of the test sample. Then pull the pull ring 707, so that the pull ring 707 drives the pull rod 706 to move. The pull rod 706 drives the connecting plate 704 to move. The connecting plate 704 drives the limiting block 703 to slide synchronously in the limiting groove 702, so that the connecting plate 704 drives the limiting rod 705 to move and separate from the first limiting hole 5 and the second limiting hole 6, thus releasing the restriction on the storage bracket 4. At the same time, the return spring 708 is compressed and begins to contract. Then, rotate the storage bracket 4 under the action of the rotating shaft 3 to adjust the angle of the storage bracket 4. At the same time, one of the rotating shafts 3 drives the pointer 16 to rotate synchronously. Determine the inclination angle of the storage bracket 4 by observing the reading of the cooperation between the pointer 16 and the scale 15. Then release the pull ring 707. Under the elastic force of the return spring 708, the connecting plate 704 drives the limiting rod 705 to squeeze into the corresponding first limiting hole 5 and the second limiting hole 6, thereby limiting and fixing the storage bracket 4. Subsequently, the test sample can be placed on the groove frame 8, and the test sample is leaned against the support block 11 and limited by the positioning groove 17, which is convenient for the test sample to fully contact with the salt spray during the salt spray test and is easy to use.

[0027] The above is only the preferred embodiment of the present invention, and does not limit the present invention in other forms. Any person skilled in the art may use the disclosed technical content to make changes or modifications into equivalent embodiments with equivalent changes and apply them to other fields. However, as long as it does not depart from the technical content of the technical solution of the present invention, any simple modification, equivalent change and modification made to the above embodiments according to the technical essence of the present invention still belong to the protection scope of the technical solution of the present invention.
