[0024] The following, with reference to the accompanying drawings, describes the embodiments and further explains the specific implementation methods of the utility model, such as the shapes and structures of the components involved, the relative positions and connection relationships between the components, the functions and working principles of the components, the manufacturing process and the operation and use methods, so as to help those skilled in the art to have a more complete, accurate and in-depth understanding of the utility model concept and technical solution of the utility model.

[0025] Reference Figure 1-4 As shown, an experimental instrument acid resistance detection device includes a box body 1, the interior of the box body 1 is divided into upper and lower parts, the lower half of the interior of the box body 1 is a retention box 8, the bottom side wall of the retention box 8 is provided with a pump liquid port 9, the top of the retention box 8 is provided with a liquid leakage port 16, and one side of the retention box 8 is also provided with a vent hole 18, the upper half of the interior of the box body 1 is a detection box 7, and a plurality of Y-shaped frames 11 are fixedly installed at the bottom of the detection box 7.

[0026] In this solution, the detection box 7 is located above the retention box 8. After the detection is completed, the acid liquid in the detection box 7 can flow into the retention box 8 through the leakage port 16. The acid liquid can be introduced into the detection box 7 again for detection next time. The vent hole 18 prevents the air pressure in the retention box 8 from being unbalanced and causing the retention box 8 to be unable to be pumped out.

[0027] Reference Figure 2 As shown, the top of the fork at the upper end of the Y-shaped frame 11 is rotatably connected to a ring clamp 13, a limit block 12 is fixedly installed on the top of the Y-shaped frame 11, and swing arms 14 are provided on the front and rear sides of the ring clamp 13. The angle between the swing arm 14 and the ring clamp 13 is less than 90 degrees, and a hollow ball 15 is provided at the end of the swing arm 14 away from the ring clamp 13.

[0028] In this solution, the swing arm 14 is obliquely arranged on the annular clamp 13, so that the test tube is at a certain angle to the swing arm 14 when clamped by the annular clamp 13. When the acid is not injected, the hollow ball 15 presses down the test tube so that the bottom of the test tube faces upward. As the acid is injected, the hollow ball 15 floats on the acid liquid surface and rises with the rise of the liquid surface, thereby driving the test tube to rotate, and the acid is poured into the test tube opening. When the acid completely covers the test tube, the swing arm 14 stops rotating due to the limit block. At this time, the mouth of the test tube faces upward, the retained bubbles are discharged, and it is completely immersed in the acid, thereby ensuring the accuracy of the detection.

[0029] Reference Figure 3 As shown, a liquid discharge port 10 is arranged inside the detection box 7, and the liquid discharge port 10 and the liquid pump port (9) are arranged on the same side wall of the box body 1.

[0030] Reference Figure 1 As shown, a top cover 2 is sleeved on the upper end of the box body 1 , a vertical rod 4 runs through the middle of the top cover 2 , and a handle 3 is fixedly provided on the upper surface of the top cover 2 .

[0031] In this solution, the vertical stick 4 can be pulled upward from the outside of the top cover 2 to open the liquid leakage port 16 so that the acid liquid can flow into the retention box 8.

[0032] Reference Figure 1 As shown, a guide tube 5 is provided on the outer surface of the front side of the box body 1 , the upper end of the guide tube 5 is fixedly connected to the discharge port 10 , the lower end of the guide tube 5 is fixedly connected to the pump port 9 , and a water pump 6 is provided in the middle section of the guide tube 5 .

[0033] In this solution, the acid liquid can be pumped upward from the retention box 8 into the detection box 7 by a water pump.

[0034] Reference Figure 2 As shown, the pump liquid port 9 is located at the lower side of the interior of the retention box 8.

[0035] In this solution, in order to prevent the acid liquid from being unable to be completely extracted, the pump liquid port is arranged at the bottom of the retention box 8 as much as possible.

[0036] Reference Figure 2 As shown, a sealing plug 17 is fixedly provided at the bottom of the vertical stick 4.

[0037] In this solution, the shape of the sealing plug 17 matches that of the leakage port 16, which can prevent the acid from leaking into the retention box.

[0038] Working principle and use process of the utility model: When the utility model is used, the experimenter inserts the bottom of the test tube into the annular clamp 13 upward, then blocks the leakage port 16 with the sealing plug 17 at the bottom of the vertical stick 4, and then injects acid. As the acid level rises, the test tube rotates under the action of the hollow ball 15 and the swing arm 14, and gradually opens to discharge bubbles upward. After the acid completely immerses the test tube, the top cover is used to seal the detection box 7. After the detection is completed, the vertical stick 4 is pulled, and the test tube is taken out for detection after the acid completely flows into the retention box 8. Then, the next batch of test tubes to be tested are replaced, the bottom of the detection box is sealed with the sealing plug 17, and the water pump is started to re-inject acid for detection.

[0039] The utility model is described above by way of example in conjunction with the accompanying drawings. It is obvious that the specific implementation of the utility model is not limited to the above-mentioned method. As long as various non-substantial improvements are made using the method concept and technical solution of the utility model, or the concept and technical solution of the utility model are directly applied to other occasions without improvement, they are all within the protection scope of the utility model.
