Description
Technical Field
[0001] The utility model relates to a test bench, in particular to a test bench used for a composite salt spray test box. Background Art
[0002] The salt spray test is an accelerated test that simulates the corrosion effect of salt spray on materials or products in the natural environment. By placing the sample in an artificial environment filled with salt spray, its corrosion resistance can be quickly evaluated. When conducting a salt spray test, the angle of sample placement is a key influencing factor, and different industry standards have different provisions for the angle of the sample. For example, the GB / T10125-2021 standard requires that the angle between the sample and the vertical direction is 20°, while the GB / T2423.17-2008 standard stipulates that it is 30°. This angle difference directly affects the amount of salt spray deposited on the surface of the sample. Studies have shown that changes in the inclination angle of the sample will cause changes in its horizontal projection area, thereby affecting the amount of salt spray deposited per unit area. When the salt spray settles in an approximately vertical direction, the sample with a smaller inclination angle will be subjected to more salt spray impact, accelerating the corrosion process. Therefore, the difference in the placement angle of the sample under different standards will directly lead to differences in the test results, thereby affecting the evaluation of the corrosion resistance of the material, making it difficult to compare and standardize the test results.
[0003] Secondly, research shows that the angle of the specimen has a significant impact on the test results, but existing methods are difficult to accurately control the angle. The currently commonly used inclined placement and suspension methods have limitations: the inclined placement lacks standardized tools to ensure angle consistency, and the suspension method is susceptible to human interference, resulting in angle changes. In addition, the lack of dedicated inspection tooling makes it difficult to avoid interference from testers, affecting the reliability of the results. The above problems not only reduce test efficiency, but also increase test complexity and cost. More importantly, existing methods are difficult to flexibly adapt to angle changes required by different standards and cannot meet diverse test needs.
[0004] The above shortcomings highlight the urgent need to develop a new dedicated test fixture to improve the accuracy, efficiency and adaptability of salt spray testing. Utility Model Content

DETAILED DESCRIPTION
[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0025] Embodiment 1: As shown in the figure, a test bench for a composite salt spray test chamber includes a test plate 1 and a base 2, one end of the test plate 1 is hinged on the base 2, and an adjustment mechanism 3 for adjusting the inclination angle of the test plate 1 is arranged between the test plate 1 and the base 2, and a plurality of saw teeth 4 are arranged at intervals on the left and right of the upper end of the test plate 1, and a drainage channel 5 running through the front and back is formed between adjacent saw teeth 4, at least one through hole 6 is opened at the lower part of each saw tooth 4, and a drainage channel 7 is formed between the corresponding through holes 6 of adjacent saw teeth 4.
[0026] Embodiment 2: As shown in the figure, different from Embodiment 1, the adjustment mechanism 3 includes a support rod 8 and a slider 9, a plurality of limit seats 10 are arranged at intervals at the lower end of the test plate 1, the slider 9 can be moved left and right and is arranged on the base 2, the support rod 8 is screwed on the base 2, and a connecting component 11 is arranged between the upper part of the support rod 8 and the corresponding limit seat 10.
[0027] In the above structure, the support rod 8 is screwed on the base 2, so that the depth of the support rod 8 extending into the base 2 can be adjusted. The upper part is connected to the limit seat 10 at the lower end of the test board 1 through the connecting assembly 11, and the slider 9 can be moved left and right on the base 2. When the slider 9 moves, it will drive the support rod 8 to move accordingly, thereby changing the angle between the test board 1 and the base 2. A plurality of limit seats 10 are arranged at intervals at the lower end of the test board 1, and each limit seat 10 corresponds to a specific tilt angle. When the support rod 8 is connected to different limit seats 10, different tilt angles will be formed. By moving the slider 9 and adjusting the position of the support rod 8, the support rod 8 can be connected to different limit seats 10, thereby realizing the precise adjustment of the tilt angle of the test board 1 to meet the requirements of different standards.
[0028] This design structure can not only accurately control the inclination angle of the test board 1, but also avoid the influence of human factors. Since the inclination angle of the test board 1 is determined by the connection position of the support rod 8 and the limit seat 10, and the connection relationship between the support rod 8 and the limit seat 10 can be adjusted by moving the slider 9, it can effectively avoid the influence of human factors on the test results, thereby ensuring the accuracy and repeatability of the test results.
[0029] In this embodiment, the connecting assembly 11 includes a stud bolt 12 and two nuts 13. A through hole 14 is opened on the limit seat 10. The upper part of the support rod 8 is located in the limit seat 10. The stud bolt 12 passes through the through hole 14 and the upper part of the support rod 8 in sequence. The exposed parts at both ends of the stud bolt 12 are respectively connected by nuts 13.
[0030] The connection assembly 11 adopts a combination design of stud bolts 12 and nuts 13, which realizes a firm connection between the support rod 8 and the limit seat 10, and ensures the convenience of angle adjustment of the test plate 1. The through hole 14 provided on the limit seat 10 provides a channel for the stud bolts 12 to pass through, and the upper part of the support rod 8 is located in the limit seat 10, which ensures the close contact between the support rod 8 and the limit seat 10 and avoids looseness and shaking. The stud bolts 12 pass through the through hole 14 and the upper part of the support rod 8 respectively, and the exposed parts at both ends of the stud bolts 12 are connected by nuts 13. By rotating the nuts 13, the stud bolts 12 and the limit seat 10 are matched, thereby realizing the connection between the support rod 8 and the limit seat 10.
[0031] This design structure can achieve precise adjustment of the angle of the test plate 1, and can ensure a firm connection between the support rod 8 and the limit seat 10 to prevent loosening or falling off, thereby improving the accuracy and reliability of the test results. At the same time, the structural design of the stud bolt 12 and the nut 13 also facilitates the adjustment of the angle of the test plate 1. Only the nut 13 needs to be rotated to achieve disassembly and assembly between the support rod 8 and the limit seat 10, thereby simplifying the operation process and improving the test efficiency.
[0032] In this embodiment, a slide groove 15 is provided on the base 2, and the slider 9 is slidably provided in the slide groove 15. A sleeve 16 is provided on the slider 9, and the support rod 8 is screwed in the sleeve 16. A locking assembly 17 is also provided between the slider 9 and the base.
[0033] In the above structure, the slide groove 15 provided on the base 2 provides a moving track for the slider 9, ensuring the moving direction and track of the slider 9, so that it can move smoothly on the base without deviation or jamming. The slider 9 is slidably arranged in the slide groove 15 and is equipped with a sleeve 16, and the lower part of the support rod 8 is screwed in the sleeve 16. This design enables the support rod 8 to move with the slider 9, which is convenient for angle adjustment. At the same time, by adjusting the penetration depth of the support rod 8, it can adapt to the limit seat 10 in different positions to meet different test requirements.
[0034] Embodiment 3: As shown in the figure, different from Embodiment 2, the locking assembly 17 includes two locking bolts 18, and two locking grooves 19 are provided on the base 2. The two locking grooves 19 are respectively located on both sides of the support rod 8 and are connected to the slide groove 15. The locking bolts 18 pass through the corresponding locking grooves 19 and are screwed to the slider 9.
[0035] In the above structure, the two locking grooves 19 opened on the base 2 are respectively located on both sides of the support rod 8 and are connected with the slide groove 15. After the locking bolt 18 passes through the corresponding locking groove 19, it is screwed with the slider 9. When the locking bolt 18 is tightened, the slider 9 can be firmly fixed in the locking groove 19 to prevent the slider 9 from moving during the test, thereby ensuring that the inclination angle of the test plate 1 remains unchanged.
[0036] This structural design can not only effectively prevent the slider 9 from moving, but also conveniently and quickly perform locking and unlocking operations. When the angle of the test board 1 needs to be adjusted, it is only necessary to loosen the locking bolt 18 to move the slider 9, adjust the connection position of the support rod 8 and the limit seat 10, and change the inclination angle of the test board 1. When the adjustment is completed, it is only necessary to tighten the locking bolt 18 to lock the slider 9 in the new position to ensure the stability of the angle of the test board 1. Such a design simplifies the operation process, improves the test efficiency, and at the same time ensures the accuracy and repeatability of the test results, effectively improving the overall performance of the test bench.
[0037] In this embodiment, a boss 20 is provided at the left end of the test board 1 , and the boss 20 is hinged to the base 2 via a rotating shaft 21 .
[0038] In the above structure, the boss 20 arranged at the left end of the test plate 1 provides a connection point for the hinge between the test plate 1 and the base 2. The boss 20 is hinged to the base 2 through the rotating shaft 21. The design of the rotating shaft 21 can ensure that the test plate 1 can rotate freely around this point, which is convenient for placing and removing the sample. This design structure can not only improve the test efficiency, but also effectively prevent the test plate 1 from shaking or shifting when placing the sample, thereby ensuring the accuracy and reliability of the test results.
[0039] In this embodiment, an escape groove 22 is provided on the upper surface of the base 2 near the left side, and the escape groove 22 is communicated with the slide groove 15 .
[0040] In the above structure, the design of the avoidance groove 22 enables the boss 20 to smoothly pass through the avoidance groove 22 without interfering with the base 2 when the test board 1 is rotating. This not only avoids the test board 1 from getting stuck or colliding, but also ensures the accuracy and stability of the angle during the rotation of the test board 1, thereby improving the reliability of the test results. In addition, the avoidance groove 22 and the slide groove 15, thereby the dripping accumulated liquid can flow along the avoidance groove 22 to the slide groove 15, thereby avoiding the accumulation of accumulated liquid in the avoidance groove.
[0041] In this embodiment, a liquid discharge slope 23 is provided on the left side of each saw tooth 4 .
[0042] The design of the drainage slope 23 makes it easier for the salt spray solution to flow to the drainage channel 5 during the test process, thereby avoiding the accumulation of the salt spray solution on the surface of the test plate 1, which leads to an increase in the error of the test result. At the same time, the design of the drainage slope 23 can also effectively prevent the salt spray solution from staying on the surface of the test plate 1 for too long, thereby reducing the corrosion of the salt spray solution to the test plate 1 and extending the service life of the test bench.
[0043] The above description is only a preferred embodiment of the utility model and is not intended to limit the utility model. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the utility model should be included in the protection scope of the utility model.
