Description

Technical Field

[0001] This utility model relates to the field of salt spray testing technology, specifically to a product testing rack for a salt spray testing machine. Background Technology

[0002] Salt spray test chambers utilize artificially prepared salt or acidic salt solutions of a certain concentration, applied via a spray device, to conduct accelerated salt spray corrosion tests under specific temperature and relative humidity conditions. They are commonly used to assess the salt spray corrosion resistance of test materials and their protective coatings, electroplating layers, etc., and to compare the differences in process quality between similar protective layer materials, allowing for better selection of protective layers. During salt spray corrosion testing, the operating temperature is generally between room temperature and 55°C and must remain constant throughout the test. The salt spray corrosion test is conducted on materials or products within a chamber of a specified working volume under constant relative humidity and temperature.

[0003] In the current salt spray test process, operators need to use readily available tools or materials, such as inert non-metallic materials, synthetic fibers, cotton fibers or other insulating materials, to place or fix the samples to meet the angle required for the sample test. In the existing technology, a salt spray rack can only fix the sample at a specific angle to test a specific type of sample. It has poor variability and cannot be freely adjusted when testing different samples.

[0004] Therefore, we proposed a product testing rack for salt spray testing machines to solve the above problems. Utility Model Content

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Example

[0024] like Figures 1-3 As shown, an embodiment of the present invention provides a product testing rack for a salt spray tester, comprising a PP plastic base frame 1 and a diagonal brace 2. The PP plastic base frame 1 has hinge grooves 3 on both sides, and a V-shaped shelf 4 is hinged in the hinge grooves 3. A perforated pad 5 is snapped into the V-shaped shelf 4. A shaft 6 is provided on the outer side wall of the V-shaped shelf 4. One end of the diagonal brace 2 has a waist-shaped hole 7, and is hinged to the V-shaped shelf 4 through the waist-shaped hole 7 and the shaft 6. A clamping screw 8 is threaded onto the waist-shaped hole 7. The other end of the diagonal brace 2 has a hook groove 9. Hooks 10 are evenly distributed on the side wall of the PP plastic base frame 1, and are snapped to the diagonal brace 2 through the hooks 10 and the hook groove 9.

[0025] like Figure 1 As shown, in some embodiments, the hinge groove 3 is provided with a pin 11, and the bottom end of the V-shaped shelf 4 is provided with a shaft hole 12. The V-shaped shelf 4 is hinged to the V-shaped shelf 4 through the shaft hole 12 and the pin 11. Through the cooperation between the shaft hole 12 and the pin 11, the V-shaped shelf 4 is hinged to the PP plastic base frame 1.

[0026] like Figure 1 As shown, in some embodiments, the inner bottom of the V-shaped shelf 4 is provided with a trapezoidal boss 13, and the bottom edge of the trapezoidal boss 13 is provided with a sedimentation solution outlet 14. The trapezoidal boss 13 is used to place some small test samples, such as screws and nuts. When the salt spray tester sprays, the salt spray generated will freely settle and deposit on the test surface of the sample in the V-shaped shelf 4. The sedimentation solution outlet 14 is used to discharge excess sedimentation solution.

[0027] like Figure 1 As shown, in some embodiments, the upper part of the V-shaped shelf 4 is provided with a slot 15, and the perforated pad 5 is snapped onto the V-shaped shelf 4 through the slot 15. The slot 15 is an assembly structure used for the installation and fixing of the perforated pad 5. The perforated pad 5 is used to place some medium-sized test samples. The diagonal brace 2, the V-shaped shelf 4, the perforated pad 5 and the clamping screw 8 are all made of PP material. PP plastic is widely recognized for its chemical stability and has excellent acid and corrosion resistance.

[0028] like Figure 3As shown, in some embodiments, the head of the clamping screw 8 is conical, and the head of the clamping screw 8 is in close contact with the shaft 6. The diagonal brace 2 is hinged to the V-shaped shelf 4 through the cooperation of the shaft 6 and the waist-shaped hole 7. Due to the setting of the waist-shaped hole 7, there is a certain amount of space at the hinge point between the diagonal brace 2 and the V-shaped shelf 4, which allows for fine adjustment of the position of the V-shaped shelf 4. After fine adjustment, the clamping screw 8 is used to fill the gap.

[0029] like Figure 1 As shown, in some embodiments, the cross-section of the hook groove 9 is semi-circular, and the cross-section of the hook 10 is spherical. With the cooperation of the hook groove 9 and the hook 10, the diagonal brace 2 is snapped onto the PP plastic base frame 1, thereby supporting and fixing the V-shaped shelf 4.

[0030] In use, the test sample is placed stably on the V-shaped shelf 4 with the test surface facing upwards. The angle of the V-shaped shelf 4 is changed by using the corresponding hooks 10 at different heights via the grooves 9 on the diagonal brace 2. There is a certain amount of clearance at the hinge point between the diagonal brace 2 and the V-shaped shelf 4 (due to the waist-shaped hole 7, there is a certain amount of clearance at the hinge point between the diagonal brace 2 and the V-shaped shelf 4, allowing for fine-tuning of the position of the V-shaped shelf 4; after fine-tuning, the position is filled using the clamping screw 8). An angle gauge (a tool for measuring or drawing angles, not shown in the figure, and needs to be prepared separately) can precisely fine-tune the position of the V-shaped shelf 4, allowing it to adjust the angle of the V-shaped shelf 4 according to the corresponding sample, so as to be suitable for testing different samples. After the angle of the test surface of the sample is adjusted, the test shelf is placed in the test chamber of the testing machine. The salt spray generated when the test chamber sprays freely settles and deposits on the test surface of the sample to carry out the salt spray corrosion test. It should be noted that the salt spray should not be sprayed directly onto the test surface of the sample.

[0031] In summary, by placing the PP plastic base frame 1 inside the test chamber of the testing machine, and then placing the test sample stably on the V-shaped shelf 4, the angle of the V-shaped shelf 4 can be changed by using the hook groove 9 on the diagonal brace 2 to engage with the hooks 10 at different heights. At the same time, since there is a certain amount of leeway at the hinge point between the diagonal brace 2 and the V-shaped shelf 4, the position of the V-shaped shelf 4 can be precisely adjusted with the help of a protractor, so that the angle of the V-shaped shelf 4 can be adjusted according to the corresponding sample, making it suitable for testing different samples.

[0032] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
