Description

Technical Field

[0001] The utility model relates to the technical field of corrosion testing, in particular to a corrosion testing box for a salt spray chamber. Background Art

[0002] Currently, in order to verify the corrosion resistance of a certain metal, it is necessary to conduct a salt spray test on it. Salt spray tests are divided into two categories: one is a natural environment exposure test, and the other is an artificial accelerated simulated salt spray environment test. In order to shorten the test time, the second category is usually used, which requires a salt spray corrosion test chamber. A salt spray corrosion test chamber is an environmental testing equipment that uses artificial simulated salt spray environmental conditions to evaluate the corrosion resistance of products or metal materials.

[0003] Chinese patent document CN210051682U discloses a composite salt spray corrosion test chamber, comprising a salt spray chamber and an equipment chamber. The chamber is equipped with a test panel fixture, a transparent cover is located on top of the chamber, and a cylinder and motor are located within the equipment chamber. However, this technical solution still suffers from the following drawbacks: While existing technology allows the test panel to be elevated for observation close to the transparent cover, a large amount of salt spray droplets may adhere to the inside of the transparent cover, making it difficult to clearly observe the test panel surface from the outside, thus presenting certain limitations.

[0004] For this purpose, a corrosion test box for a salt spray chamber is proposed. Utility Model Content

More specifically, the top cover 7 is opened, the test plate is placed on the surface of the supporting component 2, and then the top cover 7 is closed. The test solution inside the solution tank 5 is extracted through the spray component 6 and atomized and transported to the surface of the test plate, thereby conducting a salt spray corrosion test. During the test, the test personnel can observe the state of the test plate through the observation glass 8. The lifting control component 4 can be used to control the supporting component 2 to rise, so that the test plate is close to the observation glass 8 for easy observation. At the same time, the cleaning component 9 can also be used to clean the bottom surface of the observation glass 8 to avoid the adhesion of salt spray droplets, so that the observation glass 8 remains clear.

[0026] The support assembly 2 includes a support plate 201, the top surface of which is fixedly connected to a plurality of slots 203. It should be noted that the test plates used for the test can be inserted into the inner walls of the slots 203. By providing multiple slots 203, multiple tests can be accommodated simultaneously, thereby ensuring the accuracy of the test results.

[0027] The lifting control assembly 4 includes an installation box 401, which is fixedly connected to the right side of the test box 1. A first motor 402 is fixedly installed on the top surface of the installation box 401. The output end of the first motor 402 is fixedly connected to a screw rod 403.

A scraper 905 is fixedly connected to the surface of the connecting rod 903, and the scraper 905 is slidably connected to the observation glass 8. More specifically, the operation of the second motor 901 drives the reciprocating threaded rod 902 to rotate, which, under the action of the threads, drives the connecting rod 903 to slide along the inner wall of the limiting groove 904. The connecting rod 903 drives the scraper 905 to move, and the scraper 905 is used to scrape off salt spray droplets adhered to the surface of the observation glass 8, thereby maintaining the clarity of the observation glass 8.

[0030] The top surface of the support plate 201 is provided with a guide hole 202. It should be noted that, by providing the guide hole 202, the salt spray solution falling on the surface of the support plate 201 can be guided downward to the interior of the test box 1, so as to facilitate the recovery of the solution.

[0031] In summary: open the top cover 7, place the test plate on the surface of the supporting component 2, then close the top cover 7, extract the test solution inside the solution tank 5 through the spray component 6, and atomize it to the surface of the test plate, so as to carry out the salt spray corrosion test.
