Description

Technical Field

[0001] This utility model relates to the field of salt spray test chamber technology, and in particular to a sample rack for a salt spray test chamber. Background Technology

[0002] In modern industry, salt spray testing is an important method for evaluating the corrosion resistance of metallic materials, coatings, and electronic components. By simulating salt spray corrosion conditions in harsh environments such as the ocean and industrial pollution, the corrosion resistance of products can be quickly and effectively tested, providing crucial data support for product quality control and R&D improvement.

[0003] In salt spray testing, the sample holder, as the core component of the salt spray test chamber, directly affects the accuracy of the test. Traditional sample holders are mostly fixed, and the samples cannot be rotated or their angles adjusted, resulting in insufficient contact area between the samples and the salt spray, uneven corrosion, and affecting the accuracy of the test data.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0021] Example:

[0022] Please see Figures 1-5 This utility model provides a technical solution: a salt spray test chamber sample rack, including a sample rack body 1, a flipping mechanism 3 is provided on the inner side of the sample rack body 1, and a driving component is provided on the outer side of the sample rack body 1. The flipping mechanism 3 includes two flipping frames 300, and a fixed shaft 3003 is fixedly connected to the front and rear side walls of the two flipping frames 300. The end of the fixed shaft 3003 away from the flipping frame 300 is rotatably connected to the inner wall of the sample rack body 1. A combination frame 310 is rotatably connected to the flipping frame 300. A grid 9 is fixedly connected to the inner side walls of the flipping frame 300 and the combination frame 310. The flipping frame 300 can flip around the fixed shaft 3003 as the axis within the sample rack body 1. In use, the test sample is placed on the flipping mechanism 3, clamped by the grid 9, and then flipped by the driving component to increase the contact area between the sample and the salt spray, ensuring that the sample can fully accept the salt spray corrosion during the test, and improving the accuracy and reliability of the test results.

[0023] Several shelves 2 are fixedly connected to the inner side wall of the sample rack body 1. The shelves 2 are V-shaped and are used to place small samples for testing.

[0024] The drive assembly includes a servo motor 8 and a belt 7 fixedly mounted on the salt spray test chamber. The output end of the servo motor 8 is fixedly connected to the inner wall of the left fixed shaft 3003. The outer wall of the left fixed shaft 3003 is fixedly connected to the drive wheel 5. The outer wall of the right fixed shaft 3003 is fixedly connected to the driven wheel 6. The driven wheel 6 is connected to the drive wheel 5 through the belt 7.

[0025] The flip frame 300 has a slot 3001 and a hole 3002 on its side wall. The hole 3002 is connected to the slot 3001. The combination frame 310 is provided with a limiting member 4, which includes a limiting plate 401. The limiting plate 401 is fixedly connected to the combination frame 310. The inner wall of the limiting plate 401 has a receiving groove 402. A compression spring 403 is fixedly connected to the inner wall of the receiving groove 402. A locking block 404 is fixedly connected to the end of the compression spring 403 away from the receiving groove 402. The outer wall of the locking block 404 is slidably connected to the inner wall of the receiving groove 402. The receiving groove 402 is engaged with the hole 3002.

[0026] In this embodiment, the length and width dimensions of the limiting plate 401 are smaller than those of the slot 3001, ensuring that the limiting plate 401 can be smoothly inserted into the slot 3001, allowing the locking block 404 to engage with the locking hole 3002. During use, press the locking block 404 to retract it into the receiving slot 402, then open the combination frame 310, place the test sample on the grid 9, and then close the combination frame 310. The locking block 404 and the locking hole 3002 engage again, combining the combination frame 310 with the flip frame 300. The test sample is clamped inside the grid 9, which is composed of interwoven wires and is elastic, thus enabling test samples of different sizes and shapes to be clamped inside the flipping frame 300, making it highly adaptable. During testing, the servo motor 8 is started to drive the drive wheel 5 to rotate, which in turn drives the driven wheel 6 to rotate under the action of the belt 7, realizing the synchronous flipping of the two flipping frames 300. By controlling the speed and direction of the servo motor 8, the flipping angle and speed of the flipping frame 300 can be precisely controlled to meet different test requirements.

[0027] Working principle: During use, samples are sorted by size and placed on the inner side of the grid 9 of the flipping mechanism 3 and the shelf 2 respectively. The samples on the flipping frame 300 are clamped and fixed by the grid 9 and flipped under the action of the servo motor 8. During testing, the salt spray test chamber is controlled and the servo motor 8 is started to drive the drive wheel 5 to rotate. Under the action of the drive wheel 5, the belt 7 drives the driven wheel 6 to rotate, thereby driving the two flipping frames 300 to flip synchronously. By controlling the speed and direction of the servo motor 8, the flipping angle and speed of the flipping frame 300 can be precisely controlled to meet different test requirements. By increasing the contact area between the sample and the salt spray, it is ensured that the sample can fully accept the salt spray corrosion during the test, thereby improving the accuracy and reliability of the test results.

[0028] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
