Description

Technical Field

[0001] This utility model relates to the field of glass testing equipment technology, and in particular to a device for testing the chemical resistance of display glass. Background Technology

[0002] Display glass is a thin sheet of glass with an extremely smooth surface and is one of the key basic materials in the flat panel display industry. Its production process is complex, and it requires certain resistance to acid and alkali corrosion. Currently, commonly used chemical durability testing methods include the weight loss method and the haze method. The weight loss method involves immersing the sample in a chemical reagent and calculating durability by comparing the difference in weight before and after chemical etching. Specifically, the sample is immersed in a plastic container filled with acid or alkali corrosive agent, the container is sealed, and placed in a water bath heating device. The device is then vibrated and timed according to experimental requirements. Typically, testing devices are needed to fix the samples. For example, utility model patent CN218984489U discloses a device for testing the chemical resistance of carrier glass, which includes a plastic base and support columns. The plastic base is cuboid in shape and has an internal accommodating space. The bottom of each support column passes through the top wall of the plastic base and is inserted into the accommodating space of the plastic base. An mounting seat is fixedly installed in the accommodating space. The bottom of the mounting seat is fixedly connected to the plastic base, and the bottom of the support column is inserted into the mounting seat and fixedly connected to the mounting seat.

[0003] The aforementioned patent has at least the following problem: when the support column is inserted into the receiving space from top to bottom, it is inconvenient to accurately insert the bottom of the support column into the mounting base. Utility Model Content

[0004] This invention addresses the shortcomings of existing technologies by developing a chemical resistance testing device for display glass. This invention facilitates the installation of the limiting rod and the insertion of the sample, effectively improving the testing results and efficiency.

[0005] The technical solution of this utility model to solve the technical problem is as follows: a display glass chemical resistance testing device, including a base, and also including a first limiting rod and a second limiting rod. The bottom of the base is provided with several sets of limiting grooves, and the limiting grooves are provided with mounting holes. The first limiting rods are arranged in a row in the mounting holes, and the second limiting rods are arranged in a row in the mounting holes. The first limiting rods and the second limiting rods are alternately arranged in the mounting holes in the same row. The bottom of the first limiting rod and the second limiting rod are provided with limiting blocks that cooperate with the limiting grooves.

[0006] As an optimization, the first and second limit rods have the same cross-section. This facilitates the production of the base.

[0007] As an optimization, the height of the first limiting rod is smaller than the height of the second limiting rod. The sample can be inserted between the first and second limiting rods while adhering to the second limiting rod, without the need for careful alignment of the gap between the first and second limiting rods, thus improving the insertion speed of the sample.

[0008] As an optimization, the first and second limiting rods are identical, with chamfers or rounded corners at the top of their opposing sides. These chamfers or rounded corners facilitate sample insertion between the first and second limiting rods.

[0009] As an optimization, the sidewall of the limiting block is provided with stripes. This prevents the limiting block from easily detaching from the limiting groove, ensuring the installation stability of the first and second limiting rods.

[0010] Compared with the prior art, the present invention has the following beneficial effects:

[0011] By setting a first limiting rod and a second limiting rod, the sample can be easily inserted between a row of first limiting rods and a row of second limiting rods, thereby limiting and fixing the sample and preventing it from breaking during oscillation. By setting mounting holes, the first and second limiting rods can be inserted from bottom to top, thus fixing them in place and facilitating installation. By setting limiting grooves and limiting blocks, the first and second limiting rods can be prevented from coming out of the mounting holes. This invention facilitates both the installation of limiting rods and the insertion of samples, effectively improving testing results and efficiency. Attached Figure Description

[0017] To clearly illustrate the technical features of this solution, the present invention will be described in detail below through specific implementation methods and in conjunction with the accompanying drawings.

[0018] Example 1

[0019] Figure 1 and Figure 2 As one embodiment of this utility model, such as Figure 1 and Figure 2 As shown, a display glass chemical resistance testing device includes a base 1, several sets of first limiting rods 2 and several sets of second limiting rods 3. The bottom of the base 1 is provided with several sets of limiting grooves 4 arranged in an array. The limiting grooves 4 are provided with mounting holes 5 that penetrate the base 1. The first limiting rods 2 are arranged in a row in the mounting holes 5, and the second limiting rods 3 are arranged in a row in the mounting holes 5. The first limiting rods 2 and the second limiting rods 3 are alternately arranged in the mounting holes 5 in the same row. The bottom of the first limiting rods 2 and the second limiting rods 3 are provided with limiting blocks 6 that cooperate with the limiting grooves 4.

[0020] By setting the first limiting rod 2 and the second limiting rod 3, the sample can be inserted between a row of first limiting rods 2 and a row of second limiting rods 3, thereby limiting and fixing the sample and preventing it from breaking during oscillation; by setting the mounting hole 5, the first limiting rod 2 and the second limiting rod 3 can be inserted into the mounting hole 5 from bottom to top, thereby fixing the first limiting rod 2 and the second limiting rod 3, making installation convenient; by setting the limiting groove 4 and the limiting block 6, the first limiting rod 2 and the second limiting rod 3 can be prevented from coming out of the mounting hole 5.

[0021] The first limiting rod 2 and the second limiting rod 3 have the same cross-section, which facilitates the production of the base 1.

[0022] The height of the first limiting rod 2 is less than the height of the second limiting rod 3. The sample can be inserted between the first limiting rod 2 and the second limiting rod 3 while adhering to the second limiting rod 3, without the need for careful alignment of the gap between the first limiting rod 2 and the second limiting rod 3, which can improve the insertion speed of the sample.

[0023] The side wall of the limiting block 6 is provided with stripes 7. This can prevent the limiting block 6 from easily coming out of the limiting groove 4, and ensure the installation stability of the first limiting rod 2 and the second limiting rod 3.

[0024] Example 2

[0025] Figure 3 and Figure 4 In another embodiment of this utility model, the difference from the first embodiment is that the first limiting rod 2 and the second limiting rod 3 are completely identical, facilitating the production of the first limiting rod 2 and the second limiting rod 3. The tops of the opposing sides of both the first limiting rod 2 and the second limiting rod 3 are provided with chamfers or rounded corners. By providing chamfers or rounded corners, it is easier to insert the sample between the first limiting rod 2 and the second limiting rod 3.

[0026] In use, several sets of first limiting rods 2 are inserted from bottom to top into the same row of mounting holes 5. The limiting blocks 6 are pressed firmly into the limiting grooves 4. The stripes 7 prevent the limiting blocks 6 from easily coming out of the limiting grooves 4. Then, several sets of second limiting rods 3 are inserted from bottom to top into the adjacent row of mounting holes 5. The limiting blocks 6 are pressed firmly into the limiting grooves 4. The above installation process is repeated, and the first limiting rods 2 and second limiting rods 3 are inserted alternately into the remaining rows of mounting holes 5. During testing, the sample is inserted between the first limiting rods 2 and the second limiting rods 3. The sample installation is fast and the effect is good. This utility model can not only facilitate the installation of limiting rods, but also facilitate the insertion of samples, effectively improving the testing effect and testing efficiency.
