Description

Technical Field

[0001] This utility model belongs to the technical field of salt spray test chambers, and in particular relates to a salt spray spraying structure for a salt spray test chamber. Background Technology

[0002] A salt spray test chamber is an experimental device used to simulate the corrosive effects of marine environments or salty, humid air on materials and products. It is widely used in fields such as metal materials, electronic products, automotive parts, aerospace equipment, and others requiring corrosion resistance testing in salt spray environments. The salt spray test chamber simulates the salt spray corrosion process in natural environments by spraying atomized particles containing a salt solution, thereby evaluating the corrosion resistance of the tested samples. Traditional salt spray test chambers typically use a fixed nozzle structure, with the direction and angle of the salt spray pre-set.

[0003] Because the nozzle angle is fixed, the distribution of salt spray within the test chamber may be uneven, resulting in excessively high salt spray concentrations in some areas and excessively low concentrations in others. This uneven salt spray distribution can affect the accuracy and reliability of the test results; furthermore, different types of materials and products may exhibit different corrosion behaviors under salt spray conditions, and a fixed nozzle angle cannot meet the diverse testing requirements.

[0004] To address these issues, we provide a salt spray spraying structure for a salt spray test chamber. Utility Model Content

[0005] The purpose of this invention is to provide a salt spraying structure for a salt spray test chamber. Through the action of the first spray pipe, the adjustable angle of the first spray pipe can change the spraying direction and angle to make the salt spray more evenly cover all areas of the test chamber. For larger samples, the angle of the spray pipe can be adjusted to allow the salt spray to be sprayed in all directions, avoiding insufficient or excessive salt spray in some areas. This ensures that the salt spray concentration at each location in the test chamber is closer to the actual test requirements, improving the accuracy and reliability of the test results. It solves the problem that the existing method, due to the fixed nozzle angle, may result in uneven distribution of salt spray in the test chamber, leading to excessively high salt spray concentration in some areas and excessively low salt spray concentration in others.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution: This utility model is a salt spray spraying structure for a salt spray test chamber, including a test chamber body, a motor fixed on one side of the inner wall of the test chamber body, and a transmission block fixed on the output shaft of the motor;

[0007] Several first meshing blocks are fixed on the outer ring of the transmission block;

[0008] Bearings are fixed on both sides of the inner wall of the test chamber. A transmission rod is fixed to the inner ring of the bearing. A first positioning plate is fixed to one end of the transmission rod.

[0009] Another transmission rod has a transmission plate fixed to one end, a connecting frame fixed to one side of the transmission plate, and a second positioning plate fixed to one side of the connecting frame;

[0010] The transmission plate has an adjustment groove on its surface, and a number of second meshing blocks are fixed on the inner wall of the adjustment groove;

[0011] The first meshing block and the second meshing block are meshed together.

[0012] A first spray pipe is movably connected between the first positioning plate and the second positioning plate.

[0013] The present invention is further configured such that: mounting plates are fixed on both sides of the first spray pipe, and a water inlet is fixed at one end of the first spray pipe.

[0014] The present invention is further configured such that positioning holes are opened on the surfaces of both the first positioning plate and the second positioning plate;

[0015] A locator is fixed to one side of the mounting plate, and the locator includes a positioning shell.

[0016] The present invention is further configured such that: a telescopic rod is fixed on one side of the inner wall of the positioning shell, and a spring is sleeved on the outer side of the telescopic rod;

[0017] An adjustment plate is fixed to the side of the telescopic rod away from the inner wall of the positioning shell, and a locking rod is fixed to one side of the adjustment plate.

[0018] The present invention is further configured such that: the locking rod penetrates the positioning shell, and one end of the locking rod is inserted into the positioning hole;

[0019] One end of the spring is fixedly connected to the inner wall of the positioning shell, and the other end of the spring is fixedly connected to the adjusting plate;

[0020] An adjusting rod is fixed to the end of the adjusting plate away from the locking rod, and the adjusting rod passes through the inner wall of the positioning shell.

[0021] The present invention is further configured such that: both sides of the inner wall of the test chamber are fixed with brackets, and a second spray pipe is fixed inside the brackets;

[0022] Several nozzles are fixed on the upper surface of both the first and second spray pipes.

[0023] The present invention is further configured such that: both sides of the inner wall of the test chamber are fixed with placement grooves;

[0024] A support frame is placed inside the placement slot, and several placement strips are fixed on the upper surface of the support frame.

[0025] This utility model has the following beneficial effects:

[0026] 1. Through the function of the first spray pipe, the adjustable angle of the first spray pipe can make the salt spray more evenly cover all areas of the test chamber by changing the spray direction and angle. For larger samples, the angle of the spray pipe can be adjusted to make the salt spray all-round, avoiding insufficient or excessive salt spray in some areas, ensuring that the salt spray concentration in each position in the test chamber is closer to the actual test requirements, and improving the accuracy and reliability of the test results.

[0027] 2. This utility model utilizes the positioner to prevent the first spray pipe from being in prolonged contact with the salt solution during the salt spray test. This can lead to the accumulation of salt and impurities inside the pipe and nozzle, affecting the salt spray effect. The detachable design allows for the periodic removal of the first spray pipe for thorough cleaning, clearing impurities that clog the nozzle, ensuring uniform and stable salt spray, maintaining the accuracy of salt spray distribution within the test chamber, and ensuring reliable test results.

Specific Implementation Example 1

[0044] Please see Figure 1-9 This utility model relates to a salt spray spraying structure for a salt spray test chamber, comprising a test chamber body 1, a motor 2 fixed to one side of the inner wall of the test chamber body 1, a transmission block 3 fixed to the output shaft of the motor 2, a plurality of first meshing blocks 4 fixed to the outer ring of the transmission block 3, bearings 5 ​​fixed to both sides of the inner wall of the test chamber body 1, a transmission rod 6 fixed to the inner ring of the bearing 5, a first positioning plate 7 fixed to one end of one transmission rod 6, a transmission plate 8 fixed to one end of the other transmission rod 6, a connecting frame 9 fixed to one side of the transmission plate 8, and a second positioning plate 10 fixed to one side of the connecting frame 9, an adjustment groove 11 opened on the surface of the transmission plate 8, a plurality of second meshing blocks 12 fixed to the inner wall of the adjustment groove 11, the first meshing blocks 4 meshing with the second meshing blocks 12, and a first spray pipe 13 movably connected between the first positioning plate 7 and the second positioning plate 10.

[0045] Specifically, mounting plates 14 are fixed on both sides of the first spray pipe 13, and a water inlet 15 is fixed at one end of the first spray pipe 13.

[0046] Furthermore, brackets 18 are fixed on both sides of the inner wall of the test chamber body 1, and a second spray pipe 19 is fixed inside the brackets 18; a number of nozzles 20 are fixed on the upper surface of the first spray pipe 13 and the second spray pipe 19; a placement groove 21 is fixed on both sides of the inner wall of the test chamber body 1; a support frame 22 is placed inside the placement groove 21, and a number of placement strips 23 are fixed on the upper surface of the support frame 22.

[0047] The operation process of this embodiment is as follows: First, place the support frame 22 in the placement slots 21 on both sides of the inner wall of the test chamber body 1, and place the material or product to be tested on the placement strip 23 on the upper surface of the support frame 22 to complete the sample placement. Then, connect the salt solution to the first spray pipe 13 through the water inlet 15, and at the same time ensure that the second spray pipe 19 is also connected to the salt solution supply device. Turn on the motor 2, and the output shaft of the motor 2 drives the transmission block 3 to rotate. The first meshing block 4 on the outer ring of the transmission block 3 rotates accordingly. The first meshing block 4 meshes with the second meshing block 12 on the inner wall of the adjustment slot 11 of the transmission plate 8, thereby driving the transmission plate 8 to rotate around the transmission rod 6. When the transmission plate 8 rotates, it is connected to the transmission rod 6. The connecting frame 9 drives the second positioning plate 10 to move, causing the first spray pipe 13 to swing. At the same time, the nozzles 20 on the upper surface of the first spray pipe 13 and the second spray pipe 19 begin to spray salt spray. The salt spray is evenly sprayed in the test chamber to conduct salt spray corrosion tests on the samples placed on the placement strip 23. The adjustable angle of the first spray pipe 13 can change the spray direction and angle to make the salt spray more evenly cover all areas of the test chamber. For larger samples, the angle of the spray pipe can be adjusted to allow the salt spray to be sprayed in all directions, avoiding insufficient or excessive salt spray in some areas, ensuring that the salt spray concentration at each position in the test chamber is closer to the actual test requirements, and improving the accuracy and reliability of the test results. Specific Implementation Example 2

[0049] Please see Figure 5-7 Based on the first specific embodiment, both the first positioning plate 7 and the second positioning plate 10 have positioning holes 16 on their surfaces; a locator 17 is fixed on one side of the mounting plate 14, and the locator 17 includes a positioning shell 171.

[0050] Specifically, a telescopic rod 172 is fixed to one side of the inner wall of the positioning shell 171, and a spring 173 is sleeved on the outside of the telescopic rod 172; an adjusting plate 174 is fixed to the side of the telescopic rod 172 away from the inner wall of the positioning shell 171, and a locking rod 175 is fixed to the side of the adjusting plate 174.

[0051] Furthermore, the locking rod 175 penetrates the positioning shell 171, with one end of the locking rod 175 inserted into the positioning hole 16; one end of the spring 173 is fixedly connected to the inner wall of the positioning shell 171, and the other end of the spring 173 is fixedly connected to the adjusting plate 174; an adjusting rod 176 is fixedly attached to the end of the adjusting plate 174 away from the locking rod 175, and the adjusting rod 176 penetrates the inner wall of the positioning shell 171.

[0052] The operation process of this embodiment is as follows: When installing the first spray pipe 13, first align the positioners 17 on the mounting plates 14 on both sides of the first spray pipe 13 with the positioning holes 16 on the first positioning plate 7 and the second positioning plate 10; at this time, manually press the adjusting rod 176, the adjusting rod 176 drives the adjusting plate 174 to move towards the inner wall of the positioning shell 171, compressing the spring 173, and at the same time, the locking rod 175 retracts into the positioning shell 171 as the adjusting plate 174 moves; when the positioner 17 is aligned with the positioning hole 16, release the adjusting rod 176, the spring 173 restores its deformation and generates elastic force, pushing the adjusting plate 174 to move outward, the adjusting plate 174 drives the locking rod 175 to move outward. 5. Extend the positioning shell 171, and insert one end of the locking rod 175 into the positioning hole 16, thereby firmly installing the first spray pipe 13 between the first positioning plate 7 and the second positioning plate 10, ensuring that the first spray pipe 13 will not shake or shift during operation; during the salt spray test, the first spray pipe 13 is in contact with the salt solution for a long time, and salt and impurities are easily accumulated inside and in the nozzle 20, affecting the salt spray effect; the detachable design makes it convenient to remove the first spray pipe 13 periodically for a thorough cleaning of its interior, removing impurities that clog the nozzle 20, ensuring uniform and stable salt spray, maintaining the accuracy of salt spray distribution in the test chamber, and ensuring reliable test results.
