[0032] All terms used in this application have the same meanings as those understood by those of ordinary skill in the art to which this application belongs, unless otherwise specifically defined. It should also be understood that terms defined in a general dictionary, for example, should be construed as having meanings consistent with their meanings in the context of the relevant art, and should not be interpreted in an idealized or overly formal sense, unless specifically defined as such here.

[0033] Techniques, methods, and devices known to those of ordinary skill in the relevant art may not be discussed in detail, but where appropriate, the techniques, methods, and devices should be regarded as part of the specification.

[0034] Such asFigures 1 to 6 As shown, in the technical solution of the first embodiment, there are a heating component 10 and a fixing component 20. The fixing component 20 is arranged on the heating component 10. The fixing component 20 includes a fixing structure 21 and a first accommodating structure 22. The fixing structure 21 is arranged inside the first accommodating structure 22. The fixing structure 21 includes a connecting portion 211 and a plurality of supporting portions 212. The connecting portion 211 is connected to the first accommodating structure 22. The plurality of supporting portions 212 are connected to the connecting portion 211 and are arranged at intervals. Adjacent supporting portions 212 form a supporting groove, and the glass to be inspected is partially arranged in the supporting groove.

[0035] Applying the technical solution of the first embodiment, the glass sheet to be inspected is inserted into the supporting groove. The supporting portions 212 support the glass. The fixing structure 21 and the experimental chemical solution are placed into the first accommodating structure 22. The heating component 10 heats the first accommodating structure 22. By observing the state of the glass, the chemical corrosion resistance of the glass is obtained. Compared with the traditional winding fixing method, the operation of inserting the glass into the supporting groove is simpler and faster, and the glass is not easily detached. The technical solution of the first embodiment effectively solves the problems in the prior art that during the chemical resistance experiment of the cover glass, the sample is not easily fixed and the inspection efficiency is low.

[0036] As Figures 1 to 4 shown, in the technical solution of the first embodiment, the connecting portion 211 includes a first connecting section 2111 and a second connecting section 2112. There are two first connecting sections 2111. Two ends of the second connecting section 2112 are respectively connected to the first ends of the two first connecting sections 2111. The plurality of supporting portions 212 are respectively connected to the two first connecting sections 2111, and the supporting portions 212 on the two first connecting sections 2111 are arranged in one-to-one correspondence. The first connecting section 2111 and the second connecting section 2112 together form a U-shaped structure. The plurality of supporting portions 212 respectively form a plurality of supporting grooves arranged in one-to-one correspondence on the two first connecting sections 2111. Two side edges of the glass are respectively arranged in the two supporting grooves. This structure supports both side edges of the glass, and the glass is evenly stressed and not easily detached.

[0037] As Figures 1 to 4 shown, in the technical solution of the first embodiment, the distance between two adjacent supporting portions 212 arranged on the same first connecting section 2111 is 2.5 mm to 3 mm. That is, the width of the supporting groove is 2.5 mm to 3 mm. This size is larger than the maximum thickness of the general cover glass to meet the detection requirements of cover glasses of different models. The width of the supporting groove being less than 3 mm enables a larger number of supporting grooves to be distributed on a single first connecting section 2111, more control groups can be set in a single inspection, and the inspection results are more accurate.

[0038] As Figures 2 to 4As shown, in the technical solution of the first embodiment, the first accommodating structure 22 includes a cup body 221 and a cup cover 222. The fixing structure 21 is movably connected to the cup cover 222. The cup cover 222 has a sealed state close to the cup body 221 and an unsealed state away from the cup body 221. The glass to be detected is supported by the support portion 212, the fixing structure 21 is connected to the cup cover 222, the cup cover 222 is placed on the cup body 221, a chemical solution for detection is arranged in the cup body, the glass to be detected on the fixing structure 21 is immersed in the solution, and the fixing component 20 is heated by the heating component 10 to test the chemical corrosion resistance of the glass. The setting of the cup cover 222 can seal the cup body to prevent the solution from volatilizing into the air and affecting the respiratory health of the staff. A safety valve is arranged on the cup cover 222. When the air pressure in the cup body 221 is too high, the safety valve opens to discharge the gas. The setting of the safety valve avoids the problem of explosion caused by too high air pressure in the cup body 221.

[0039] As Figures 2 to 4 shown, in the technical solution of the first embodiment, the cup cover 222 has a limiting groove 2221. The connecting portion 211 further includes a limiting section 2113. The limiting section 2113 is connected to the first connecting section 2111 and is arranged in one-to-one correspondence. The projected area of the limiting section 2113 in the vertical direction is larger than the projected area of the first connecting section 2111 in the vertical direction. The limiting section 2113 is movably arranged in the limiting groove 2221. The upper width of the limiting groove 2221 is larger than the lower width. The width of the limiting section 2113 is larger than the lower width of the limiting groove 2221 and smaller than the upper width of the limiting groove 2221. The width of the first connecting section 2111 is smaller than the lower width of the limiting groove. The limiting section 2113 is inserted into the upper part of the limiting groove 2221. Since the width of the limiting section 2113 is larger than the lower width of the limiting groove 2221, the connecting portion 211 will not fall off from the cup cover 222 under the action of gravity.

[0040] As Figures 2 to 4 shown, in the technical solution of the first embodiment, there are two fixing structures 21. The two fixing structures 21 are movably connected to the limiting groove 2221. Each fixing structure 21 can support two opposite sides of the glass. The setting of the two fixing structures 21 supports four points on the glass, making the glass more stable. Since the two fixing structures 21 are movably connected to the limiting groove 2221, the distance between the two fixing structures 21 can be adjusted to be applicable to glasses of different sizes.

[0041] As Figures 4 to 6As shown, in the technical solution of the first embodiment, the cup lid 222 includes a blocking portion 2222, a limiting portion 2223, and an operating portion 2224. The blocking portion 2222 is connected to the limiting portion 2223, and the operating portion 2224 is connected to the blocking portion 2222 and is located on the side of the blocking portion 2222 away from the limiting portion 2223. The limiting groove 2221 penetrates through the limiting portion 2223 and the blocking portion 2222. The blocking portion 2222 blocks the cup body 221 to prevent the solution from volatilizing into the air. The limiting portion 2223 restricts the movement of the blocking portion 2222 to prevent the blocking portion 2222 from detaching from the cup body 221. The setting of the operating portion 2224 facilitates the staff to open or close the cup lid 222. The penetration of the limiting groove 2221 through the limiting portion 2223 and the blocking portion 2222 facilitates the installation and disassembly of the connecting portion 211.

[0042] As Figures 4 to 6 shown, in the technical solution of the first embodiment, the projected area of the blocking portion 2222 in the vertical direction is larger than the projected area of the inner circle of the cup body 221 in the vertical direction, and the projected area of the limiting portion 2223 in the vertical direction is smaller than the projected area of the inner circle of the cup body 221 in the vertical direction. When the blocking portion 2222 is in the blocking state, the blocking portion 2222 completely covers the inner circle of the cup body 221 to prevent the solution from volatilizing to the outside. The limiting portion 2223 is located inside the cup body 221 and contacts the inner wall of the cup body 221 to prevent the blocking portion 2222 from moving.

[0043] It should be noted that all components within the fixing assembly 20 are made of peek material that is resistant to high temperatures, acids, and alkalis, facilitating various conventional chemical resistance reagent tests.

[0044] As Figure 1 shown, in the technical solution of the first embodiment, the heating assembly 10 includes a heating structure 11, a mounting frame structure 12, and a second accommodating structure 13. The second accommodating structure 13 is provided on the heating structure 11, the mounting frame structure 12 is connected to the second accommodating structure 13, and the first accommodating structure 22 is inserted through the mounting frame structure 12 and partially located inside the second accommodating structure 13. The heating structure 11 heats the second accommodating structure 13. There is a liquid such as water or oil inside the second accommodating structure 13. The mounting frame structure 12 is provided with an opening for the cup body 221 to be placed in. The cup body 221 is placed through the opening, and the cup body 221 is immersed in the liquid inside the second accommodating structure 13. The heating assembly 10 performs water bath heating or oil bath heating on the cup body. The setting of the mounting frame structure 12 plays a limiting role on the cup body 221 to prevent the cup body from shaking and tipping due to the bubbles generated by the boiling of the liquid inside the second accommodating structure 13. A handle is provided on the outside of the second accommodating structure 13, facilitating the staff to remove the second accommodating structure 13 and recycle the water or oil inside. The second accommodating structure 13 is made of transparent high-temperature-resistant borosilicate glass, facilitating the direct observation of the remaining amount of the heating medium inside the second accommodating structure 13. As Figure 1As shown in the figure, in the technical solution of the first embodiment, the mounting frame structure 12 has a liquid filling port 121. The liquid filling port 121 is connected to the liquid inlet pipeline and is also connected to the second accommodating structure 13. The setting of the liquid filling port 121 facilitates the staff to timely introduce the heating medium into the second accommodating structure 13, avoiding the too low liquid level of the heating medium and affecting the test results.

[0045] The difference between the technical solution of the second embodiment and that of the first embodiment is that in the technical solution of the second embodiment, a threaded connection is adopted between the cup body 221 and the cup cover 222. The fixed manner of the threaded connection is more compact and has a better sealing effect.

[0046] As described above, an experimental device and an experimental device kit are provided. The device includes a heating chassis (heating structure 11), a medium chamber (second accommodating structure 13), and a sample chamber (first accommodating structure 22). The heating chassis includes: a heating panel, a temperature sensor, a temperature display screen, a cooling button, a heating button, a start button, and an external power plug; the heating panel is located on the upper surface of the heating chassis, and the material is a ceramic insulating shell. The heating wire is enclosed inside the heating plate. The temperature sensor is used to detect the temperature of the heating panel, and the temperature sensor is connected to the temperature display screen. The temperature display screen, the cooling button, the heating button, and the start button are arranged in sequence from left to right in the front of the heating chassis, and the external power plug is located at the right rear side of the heating chassis. The experimental kit includes a medium chamber and a sample chamber. The medium chamber is made of transparent borate glass and consists of a hollow circle (including but not limited to 9) parallel to the X-axis and Y-axis directions on the upper surface and a lower closed cavity. The water injection port (liquid addition port 121) is located at the right rear of the upper surface (mounting frame structure 12) of the medium chamber. Handles are provided on both the left and right sides of the medium chamber for easy movement of the medium chamber. The hollow circle on the upper surface is used to place the sample chamber. The sample chamber of the experimental kit is composed of a sample cup (cup body 221), a sample cup cover (cup cover 222), and a sample rack (fixing structure 21). The sample cup is made of PEEK material that is resistant to high temperature and acid-base. A groove (limiting groove 2221) is provided under the cup cover, and a buckle (limiting section 2113) is provided above the sample rack, which can be closed with the groove of the sample cup cover to form a whole. Small teeth (supporting parts 212) are evenly distributed at equal intervals on both the left and right sides inside the sample rack for fixing the sample. After the experiment, the medium chamber can be directly removed for the recovery of the heating medium, avoiding the inconvenience of moving heavy equipment to recover the medium. The medium chamber of the device is made of transparent heat-resistant borosilicate glass, which not only facilitates the direct observation of the remaining amount of the heating medium in the medium chamber, so as to add the heating medium in time, but also avoids potential safety hazards. The device has a supporting independent sample chamber. Each sample chamber is composed of a sample cup, a sample cover, and a sample support. The sample cover and the sample support can be adjusted arbitrarily to facilitate the support of samples of various specifications and sizes. The device has a supporting independent sample chamber. Small teeth are provided on the sample support in the sample chamber for fixing and supporting the sample. The small tooth structure of the sample support makes full use of the vertical space structure to increase the number of samples to be detected, greatly improving the detection efficiency and solving the problem of detecting a large number of samples simultaneously. The device has a supporting independent sample chamber. Each sample chamber is composed of a sample cup, a sample cover, and a sample support. The sample cup is made of PEEK material that is resistant to high temperature and acid-base, facilitating various chemical reagent resistance tests.In a specific implementation of the present application, connect the external power plug of the device to the power supply, press the start button to start the device, place the medium above the heating chassis, add the medium in the medium chamber, which is generally common heating media in the laboratory such as ultrapure water and silicone oil, press the temperature up and down buttons to adjust to the required temperature, insert 2 sample racks into the grooves of the sample cover and move them to the required size, insert the samples onto the small teeth of the sample racks for fixation, add the required chemical resistance test reagents in the sample cups, which are generally common corrosive reagents such as acid solutions and alkali solutions, place the fixed samples into the sample cups, pass the sample cups through the hollow circle and place them in the medium chamber for heating. If the heating time is long (more than 6 hours), the water level of the heating medium in the medium chamber can be observed and the medium can be added through the water injection port. After the experiment, press the start button to turn off the device, take out the sample chamber from the medium chamber and remove the test samples. After the sample chamber is completely taken out, the medium in the medium chamber can be recycled.
