Description

Technical Field

[0001] The utility model relates to the technical field of salt spray testing, in particular to a salt spray detection fixing fixture. Background Art

[0002] Salt spray test is an environmental test that mainly uses artificial simulated salt spray environment conditions created by salt spray test equipment to evaluate the corrosion resistance of products or metal materials. It is divided into two categories, one is natural environment exposure test, and the other is artificial accelerated simulated salt spray environment test. Artificial simulated salt spray environment test uses a test equipment with a certain volume space - salt spray test chamber, in which a salt spray environment is artificially created to evaluate the salt spray corrosion resistance quality of the product. During the test, the placement angle of the sample has a significant impact on the results of the salt spray test.

Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of the embodiments of the present invention, "plurality" means two or more, unless otherwise specifically defined.

[0025] In the embodiments of the present invention, unless otherwise expressly specified or limited, the terms "installed," "connected," "connected," "fixed," etc. should be understood in a broad sense. For example, they may refer to fixed connection, detachable connection, or integration; mechanical connection, electrical connection; direct connection, indirect connection through an intermediate medium; internal communication between two components, or interaction between two components. Those skilled in the art will understand the specific meanings of the above terms in the embodiments of the present invention based on specific circumstances.

[0026] In one embodiment of the present invention, Figures 1 to 7 As shown, a salt spray detection fixture is provided, including a salt spray machine body 1, wherein a plurality of crossbeams 2 are detachably installed in the salt spray machine body 1, and a plurality of mounting grooves 21 and a plurality of support plates 22 are provided on the top of each crossbeam 2. Each support plate 22 is respectively connected to a support plate 22, and a plurality of air holes 221 are passed through the support plate 22 in front and back, and an adjusting column 23 is detachably connected to each air hole 221.

[0027] Furthermore, each of the adjustment posts 23 has a thread 222 on its outer edge, and the adjustment posts 23 are connected to the thread 222 within the air hole 221. Specifically, when installing the adjustment posts 23, the thread 222 of the adjustment posts 23 is screwed into the air hole 221 to adjust the length of the adjustment posts 23 exposed outside the air hole 221, thereby adjusting the angle between the cover and the bottom of the mounting slot 21 after the cover rests on the adjustment posts 23. At the same time, the threads 222 on the adjustment posts 23 form a thread 222 groove, and the side skirt of the cover can be hung in the thread 222 groove of the adjustment posts 23, making the cover more stable during installation.

[0028] Furthermore, each of the adjustment posts 23 includes a mounting portion 231 and a support portion 232, and the radius of the support portion 232 is larger than the radius of the mounting portion 231. Specifically, when the adjustment post 23 is installed with the air hole 221, it is connected to the air hole 221 via the mounting portion 231. After installation, the portion of the adjustment post 23 exposed outside the air hole 221 includes at least the support portion 232. When the angle of the face cover needs to be more vertical, part of the mounting portion 231 can be unscrewed, so that the portion of the adjustment post 23 exposed outside the air hole 221 includes the support portion 232 and part of the mounting portion 231. At the same time, by setting the radius of the support portion 232 to be larger than the radius of the mounting portion 231, the face cover can be more stable when it rests on the adjustment post 23.

[0029] Furthermore, the support portion 232 is provided with a groove 233 on a side away from the mounting portion 231. The groove 233 is an annular structure coaxial with the support portion 232. Specifically, unlike the threaded groove 222 described above for hanging the side skirt of the face cover on the adjustment column 23, the adjustment column 23 includes a mounting portion 231 and a support portion 232. By providing the groove 233, the side skirt of the face cover can be hung in the groove 233, making the face cover more stable during installation.

[0030] Furthermore, the inner side wall of each installation groove 21 is inclined to one side, and the angle between the inner side wall and the inner bottom of each installation groove 21 is 15° to 25°.

[0031] Furthermore, a fixing portion 3 is provided at the bottom of the crossbeam 2 for realizing detachable installation in the salt spray machine body 1 .

[0032] Working principle: When in use, each crossbeam 2 is installed in the salt spray machine body 1, and then each face cover is placed horizontally in the installation groove 21; when a face cover with a higher height is required, a support plate 22 is installed in the rear installation groove 21, and then the face cover is placed in the front installation groove 21, and the bottom of the face cover can be placed in the installation operation, and the top of the face cover is against the support plate 22. When conducting a salt spray test, the front side of the face cover can directly contact the salt spray, and the salt spray passes through the air holes 221 on the support plate 22 to contact the back side of the face cover, so that the front and back sides of the two face covers can be subjected to salt spray tests at the same time. Compared with the horizontally arranged storage plate, the vertical space in the salt spray machine body 1 can be fully utilized, thereby achieving More face covers can be subjected to salt spray tests at one time; when the inclination angle of the face cover needs to be adjusted, the adjusting column 23 can be installed in the air hole 221 of the support plate 22, and the face cover can be placed on the adjusting column 23 to adjust the angle of the face cover. In addition, according to the shape of the face cover, multiple adjusting columns 23 can be installed in the air holes 221 suitable for each position, so that a mounting cavity is formed between the adjusting columns 23, and the face cover can be fixed therein to prevent the face cover from sliding, and the range of use is wide; in addition, in order to make the inclination angle of the face cover larger, the positional relationship between the mounting groove for mounting the support plate and the mounting groove for fixing the bottom of the face cover can be adjacent, or there can be several mounting grooves between the two mounting grooves.

[0033] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
