[0002] Salt spray testing is an environmental test that uses artificially simulated salt spray environment conditions created by salt spray testing equipment to assess the corrosion resistance of products or metal materials. It is divided into two main categories: natural environment exposure test and artificial accelerated simulated salt spray environment test. Salt spray test requires the use of spraying devices to spray salt spray.

[0003] Patent application CN201922319713.5 discloses an adjustable spray device for a salt spray test chamber. This application describes a device with distance scale lines on the side walls of both the first and second measuring rods. Under a specified working air pressure, the height of the air nozzle is raised or lowered by rotating a threaded screw and bearing within a threaded hole. An electric push rod also drives the extension and retraction of the injection sleeve within the salt spray nozzle, thereby adjusting the distance between the air and the salt spray nozzle. By observing the extension and retraction distances of the first and second measuring rods corresponding to the air nozzle and salt spray nozzle, the distribution distance and state of the air nozzle and salt spray nozzle can be more accurately determined, ensuring the accuracy of the experimental data.

[0004] Compared with the spray devices in the above documents, depending on the salt spray test, it is sometimes necessary to adjust the spray volume and droplet size. However, the salt spray nozzle in this application is fixed through the chamber, making nozzle replacement and adjustment more troublesome and resulting in lower work efficiency.

Detailed Implementation

[0017] 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.

[0018] The adjustable spray device for salt spray testing disclosed in this utility model is mainly used in scenarios where it is sometimes necessary to adjust the spray volume and droplet size according to different salt spray tests. However, the salt spray nozzle of this application is fixed through the box, making nozzle replacement and adjustment troublesome and resulting in low work efficiency.

[0019] Reference Figure 1 and Figure 2 An adjustable spray device for salt spray testing includes a housing 1. A connecting pipe 2 is fixedly installed on the lower left side of the housing 1. A sleeve 3 is fixedly installed on the right side inside the housing 1. A fixing rod 4 is slidably connected inside the sleeve 3. A first spring 5 is sleeved on the outside of the fixing rod 4. A stabilizing platform 6 is fixedly installed on the right side of the fixing rod 4. An adjusting plate 7 is rotatably connected to the right side of the stabilizing platform 6. A through pipe 8 is fixedly installed on the left side of the adjusting plate 7. A nozzle 9 is fixedly installed on the right side of the through pipe 8. A top rod 10 is fixedly installed on the left side of the fixing rod 4.

[0020] In this embodiment: When adjusting the spray volume and droplet size during a salt spray test, push the top rod 10 to the right, causing the fixing rod 4 to slide within the sleeve 3. This rightward sliding of the fixing rod 4 compresses the first spring 5, causing the stabilizing platform 6 and the adjusting plate 7 to slide to the right within the housing 1. Simultaneously, the adjusting plate 7 slides to the right, causing the through pipe 8 to slide to the right, thus disengaging the through pipe 8 from the connecting pipe 2. Then, rotate the adjusting plate 7 on the stabilizing platform 6, causing the desired nozzle 9 to rotate to the lower side, aligning the through pipe 8 with the connecting pipe 2. Finally, release the top rod 10, relieving the pressure on the first spring 5. The first spring 5 resets and drives the fixing rod 4 to slide to the left inside the sleeve 3, which in turn drives the stabilizing platform 6 and the adjusting plate 7 to slide to the left inside the housing 1. The through pipe 8 also slides to the left along with the adjusting plate 7, thus locking into the connecting pipe 2. The setting of the top rod 10 and the first spring 5 improves the ease of adjusting and replacing the nozzle 9, increases the operating speed, and thus improves work efficiency. The left end of the through pipe 8 is designed with a bevel, which improves the stability and sealing of the engagement with the connecting pipe 2, reduces the chance of leakage, and facilitates the rapid adjustment of the nozzle 9 according to the requirements of the salt spray test, thereby improving work efficiency and expanding the applicability of the spray device.

[0021] Reference Figure 1 , Figure 3 and Figure 4 In a preferred embodiment, the adjusting plate 7 has a sliding groove 11 inside, and a locking block 12 is slidably connected inside the sliding groove 11. A second spring 13 is provided between the sliding groove 11 and the locking block 12. A locking groove 14 is provided on the right side inside the housing 1. A mounting bracket 15 is slidably connected to the left side of the connecting pipe 2. A locking ring 16 is rotatably connected to the outside of the connecting pipe 2. Locking blocks 17 are fixedly installed on the front and rear sides of the mounting bracket 15. Locking grooves 18 are provided inside the locking blocks 17. A filter screen 19 is fixedly installed on the right side inside the mounting bracket 15. A scraper 20 is fixedly installed on the right side of the outside of the mounting bracket 15.

[0022] In this embodiment: When the adjusting plate 7 rotates, one side of the locking block 12 has a spherical design. As the adjusting plate 7 rotates, the locking groove 14 will press the locking block 12, causing the locking block 12 to slide into the slide groove 11 and compress the second spring 13, causing the locking block 12 to disengage from the locking groove 14. When the adjusting plate 7 rotates to the designated position, the second spring 13 returns to its original position, driving the locking block 12 to slide out of the slide groove 11 and into the locking groove 14, providing a certain sense of tactile feedback. This helps to remind the operator that the nozzle 9 has rotated to the designated position and can proceed to the next step, facilitating confirmation of the accuracy of the nozzle 9's rotation position. Before using the connecting pipe 2, the mounting bracket 15 is inserted into the connecting pipe 2, and the locking block 17 on the mounting bracket 15 will also... The locking ring 16 is passed through a larger locking groove 18, and then the locking ring 16 is rotated so that the narrower locking groove 18 on the locking ring 16 fits against the locking block 17, thereby locking the locking block 17 and locking the mounting bracket 15, improving the stability of the mounting bracket 15. The filter screen 19 on the mounting bracket 15 can intercept larger particles in the brine, preventing larger particles from being transported into the nozzle 9 and causing damage to the nozzle 9. At the same time, when the mounting bracket 15 is disassembled and removed, the scraper 20 fits against the inner wall of the connecting pipe 2 and scrapes the inner wall of the connecting pipe 2, scraping off the salt crystals attached to the inner wall of the connecting pipe 2, preventing excessive salt crystals from attaching to the connecting pipe 2 and affecting the flow rate of the connecting pipe 2.

[0023] The above description is merely a preferred embodiment of this utility model, but the protection scope of this utility model is not limited thereto. The substitutions may be replacements of some structures, devices, or method steps, or they may be complete technical solutions. Equivalent substitutions or modifications made based on the technical solution and inventive concept of this utility model should all be covered within the protection scope of this utility model.
