A limiting groove 4 is formed on the front side of the test chamber body 3, and a protective plate 5 is engaged with the inner side of the limiting groove 4. A first slot 6 is formed on the front side of the protective plate 5, extending into the interior of the test chamber body 3. A second slot 7 is formed on the inner wall of the first slot 6, and a circular groove 8 is formed on the inner side of the first slot 6. A first locking block 15 is engaged with the inner side of the first slot 6, and a second locking block 16, matching the second slot 7, is fixedly connected to the outer side of the first locking block 15. The second locking block 16 engages with the inner side of the circular groove 8. A display screen 29 is provided on the front side of the protective plate 5. The test chamber body 3... One side is provided with a wire hole 14. In use, in order to improve the stability of the installation of the protective plate 5, the second locking block 16 is inserted into the circular groove 8, and then the angle of the second locking block 16 is adjusted to a position that is not corresponding to the second locking groove 7. This can effectively lock the protective plate 5 to prevent it from shifting, thereby improving the stability of the installation of the protective plate 5. When the protective plate 5 needs to be removed later to maintain the internal equipment of the test chamber 3, the second locking block 16 is adjusted to a corresponding angle to the second locking groove 7, and then the first locking block 15 can be pulled out directly. This can achieve the effect of convenient and quick disassembly and assembly of the protective plate 5, and also facilitate the user to maintain the inside of the test chamber 3.

[0023] refer to Figures 1 to 4 A retaining spring 9 matching the second retaining block 16 is installed on the inner side of the circular groove 8.

A first protrusion 18 is fixedly connected to the front side of the sealing block 17. The shape of the corner of the first protrusion 18 is arc-shaped. Due to the presence of the retaining spring 9, the retaining spring 9 can engage the second retaining block 16 at the second point, thereby improving the stability of the engagement of the protective plate 5 at the second point.

[0024] refer to Figures 1 to 3 A rubber pad 10 is fixedly connected to the inner side of the limiting groove 4. The rubber pad 10 is 5 mm thick and is located on the inner side close to the first slot 6. The front side of the rubber pad 10 is in contact with the rear side of the protective plate 5. A handle 13 is fixedly connected to the front side of the protective plate 5. The handle 13 has an arc-shaped corner. Due to the presence of the rubber pad 10, it has good anti-slip properties and rubber elasticity. When the second locking block 16 is engaged, the first locking block 15 will press down, which will press the rubber pad 10 down. After the second locking block 16 is engaged, the rebound of the rubber pad 10 can make the second locking block 16 engage more tightly, thereby further improving the stability of the point engagement of the protective plate 5.

[0025] refer to Figure 1 A rectangular opening 11 is provided on the front side of the protective plate 5. The rectangular opening 11 communicates with the interior of the test chamber 3. A transparent glass 12 is fixedly connected to the inside of the rectangular opening 11, and the transparent glass 12 covers the inside of the rectangular opening 11. Because of the opening of the rectangular opening 11, the user can directly view the interior of the test chamber 3 through the transparent glass 12 without opening the protective plate 5, which is conducive to the user's constant observation of the internal condition of the test chamber 3.

[0026] refer to Figures 1 to 5 A ventilation opening 19 is provided on one side of the test chamber 3, which communicates with the interior of the test chamber 3. A strip opening 22 is provided on the rear side of the test chamber 3, which communicates with the inside of the ventilation opening 19. A filter plate 23 is inserted into the inside of the strip opening 22, which covers the inside of the ventilation opening 19. The opening of the ventilation opening 19 facilitates the air circulation inside the test chamber 3, thereby achieving a relative heat dissipation effect. The filter plate 23 can effectively block dust and pollutants in the circulating air, so as to prevent a large amount of dust or pollutants from being sent into the test chamber 3 through the ventilation opening 19. At the same time, the strip opening 22 also makes it easy for the user to pull out the filter plate 23 for later cleaning or maintenance.

[0027] refer to Figures 1 to 5A first groove 20 is formed on the inner wall of the vent 19. A first magnet 21 is fixedly connected to the inner side of the first groove 20.

The position of the second magnet 25 corresponds to the position of the baffle 27. The other side of the baffle 27 is made of ferromagnetic material. Due to the presence of the first magnet 21, the adsorption of the first magnet 21 can effectively limit the position of the filter plate 23, which can effectively improve the stability of the filter plate 23 installation. At the same time, it will not hinder the user from pulling it out normally through the strip opening 22 later. When the vent 19 structure is not used, the baffle 27 is pulled down through the slide groove 26, and the vent 19 is sealed by the baffle 27 to achieve a relative sealing and protection effect.

[0028] refer to Figure 1 The base 1 is fixedly connected to the bottom end of the support leg 2. The support leg 2 is fixedly connected to the four sides of the bottom end of the base 1 near the corner. The bottom end of the support leg 2 is coated with an anti-slip layer. The anti-slip layer covers the bottom end of the support leg 2. Due to the presence of the support leg 2, the bottom end of the base 1 can be effectively supported. Its anti-slip layer is an anti-slip coating, which can effectively improve the friction of the bottom end of the support leg 2, thereby making the base 1 more stable.

[0029] Operating principle and advantages: During use, to improve the stability of the protective plate at point 5, the second locking block 16 is inserted into the circular groove 8. Then, the angle of the second locking block 16 is adjusted so that it does not correspond to the second locking groove 7, thus effectively locking the protective plate at point 5 to prevent displacement and improve the stability of the installation. Later, when the protective plate 5 needs to be removed for maintenance of the internal equipment of the test chamber 3, the second locking block 16 is adjusted to the corresponding angle with the second locking groove 7, and then the first locking block 15 can be directly pulled out, thus achieving convenient... The quick disassembly and assembly of the protective plate 5 facilitates user maintenance of the interior of the test chamber 3. Due to the presence of the retaining spring 9, the second retaining block 16 can be engaged a second time, further enhancing the stability of the protective plate 5 engagement. The rubber pad 10 provides excellent anti-slip properties and elasticity. When engaging the second retaining block 16, the first retaining block 15 presses downwards, further pressing the rubber pad 10 down. After the second retaining block 16 is engaged, the rebound of the rubber pad 10 ensures a more secure engagement. The tight fit further enhances the stability of the 5-point snap-fit ​​of the protective plate. Due to the rectangular opening 11, users can directly view the interior of the test chamber 3 through the transparent glass 12 without opening the protective plate 5, facilitating constant monitoring of the internal condition. The ventilation opening 19 promotes airflow within the test chamber 3, achieving a relative heat dissipation effect. Its filter plate 23 effectively blocks dust and pollutants in the circulating air, preventing large amounts of dust or pollutants from being sent into the test chamber through the ventilation opening 19. Inside the test chamber 3, the strip opening 22 also facilitates the user to pull out the filter plate 23 for later cleaning or maintenance. Due to the presence of the first magnet 21, the adsorption of the first magnet 21 can effectively limit the position of the filter plate 23, which can effectively improve the stability of the filter plate 23 installation. At the same time, it will not hinder the user from pulling it out normally through the strip opening 22 later. When the ventilation opening 19 structure is not used, the baffle 27 can be pulled down through the slide groove 26 to seal the ventilation opening 19, thereby achieving a relatively sealed protection effect.
