It is widely used in industrial manufacturing, scientific research and development, quality inspection, certification and calibration, and other fields, and is an important foundation for ensuring product quality and promoting technological innovation.

[0003] The main purpose of exhaust ducts in testing equipment is to remove harmful gases, heat, dust, or explosive substances to ensure personnel safety, normal equipment operation, and environmental compliance. However, the exhaust duct ports in most traditional testing equipment are not easy to adjust, and the fixed ports cannot match the air volume requirements under different working conditions (such as requiring a larger air volume for high-temperature testing and a reduced air volume for low-temperature testing). Furthermore, it can easily lead to turbulent airflow inside the equipment, affecting the uniformity of temperature / humidity (such as excessive temperature difference inside the environmental test chamber). Utility Model Content

[0004] To overcome the shortcomings of existing technologies, the exhaust pipe ports in most traditional testing equipment are not easy to adjust, and the fixed ports cannot match the air volume requirements under different working conditions. Furthermore, they can easily lead to turbulent airflow inside the equipment, affecting the uniformity of temperature and humidity. This utility model proposes an adjustable testing device.

[0005] The technical solution adopted by this utility model to solve its technical problem is: an adjustable testing device, including a shell, a door panel rotatably connected to one side of the shell, an exhaust pipe fixedly connected to the top of the shell, two exhaust pipes, and an adjustment mechanism provided on the inner wall of the exhaust pipe;

[0006] The adjustment mechanism includes two folding plates. One end of each folding plate is fixedly connected to the inner wall of a corresponding exhaust pipe, and the other end of each folding plate is fixedly connected to a connecting plate. Both sides of the connecting plate are attached to the inner wall of the exhaust pipe. A first slider is fixedly connected to one side of the connecting plate, and a first groove is provided on one side of the exhaust pipe. The surface of the first slider is slidably connected to the inner wall of the first groove. A second slider is fixedly connected to the opposite side of the two connecting plates, and a second groove is provided on one side of the exhaust pipe. The surface of the second slider is slidably connected to the inner wall of the second groove.

[0007] Preferably, a first support plate and a second support plate are fixedly connected to one side of the exhaust pipe, a motor is fixedly installed on one side of the first support plate, a threaded rod is fixedly connected to the output end of the motor, and the surface of the threaded rod is rotatably connected to the inner cavity of the first support plate and the second support plate.

[0008] Preferably, a threaded hole is provided on one side of the second slider, and the inner wall of the threaded hole is threadedly connected to the surface of the threaded rod.

[0009] Preferably, a filter membrane is fixedly connected to one side of the connecting plate, and a coil spring is fixedly connected to one end of the filter membrane.

[0010] Preferably, a third support plate is fixedly connected to the top of the outer shell, and there are two third support plates. A connecting roller is rotatably connected to the inner cavity of the third support plate, and the other end of the coil spring is fixedly connected to the surface of the connecting roller.

[0011] Preferably, a through groove is provided on one side of the exhaust pipe, and the surface of the filter membrane is attached to the inner wall of the through groove.

[0012] Preferably, a gear is fixedly connected to one end of the connecting roller, and a toothed plate is fixedly connected to one side of the first slider, with the teeth of the toothed plate meshing with the teeth of the gear.

[0013] The advantages of this utility model are:

[0014] The heat and harmful gases generated during testing inside the casing of this utility model are discharged through two exhaust pipes. The motor can be regarded as the driving source of the adjustment mechanism. The motor is supported by the first and second support plates. The motor can drive the threaded rod to rotate along the second support plate. The folding plate in the adjustment mechanism can retract or extend along the inner wall port of the exhaust pipe. When the folding plate retracts, it opens the port of the exhaust pipe. The continuous retraction of the folding plate increases the open area of ​​the exhaust pipe port, realizing the adjustment of different areas. The folding plate lifts and lowers simultaneously, driving the connecting plate to lift and lower synchronously. The first slider on one side of the connecting plate can slide along the first slide groove to improve the stability of the folding plate retraction. The second slider fixes the two sets of connecting plates into one piece. The second slider can slide along the second slide groove to further improve the stability of the folding plate lifting and lowering. Furthermore, through the threaded hole on the second slider and the threaded rod, the second slider, the connecting plate and the folding plate automatically lift and lower while the threaded rod rotates, ensuring the convenience of adjustment. This solves the problems of the exhaust pipe port being inconvenient to adjust in most traditional testing equipment, the fixed port being unable to match the air volume requirements under different working conditions, and the easy occurrence of airflow disturbance inside the equipment, affecting the uniformity of temperature / humidity.

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 scope of protection of the present utility model.

[0023] The following is in conjunction with the appendix Figures 1-5 This application will be described in further detail.

[0024] This application discloses an adjustable testing device. (Refer to...) Figures 1 to 4 An adjustable testing device includes a housing 1, a door panel 2 rotatably connected to one side of the housing 1, and an exhaust pipe 3 fixedly connected to the top of the housing 1. There are two exhaust pipes 3, and an adjustment mechanism 4 is provided on the inner wall of the exhaust pipe 3.

[0025] The adjusting mechanism 4 includes two folding plates 401. One end of each folding plate 401 is fixedly connected to the inner wall of a corresponding exhaust pipe 3, and the other end of each folding plate 401 is fixedly connected to a connecting plate 402. Both sides of the connecting plate 402 are attached to the inner wall of the exhaust pipe 3. A first slider 403 is fixedly connected to one side of the connecting plate 402, and a first groove 405 is provided on one side of the exhaust pipe 3. The surface of the first slider 403 is slidably connected to the inner wall of the first groove 405. A second slider 404 is fixedly connected to the opposite side of the two connecting plates 402. A second slide groove 406 is provided on one side, and the surface of the second slider 404 is slidably connected to the inner wall of the second slide groove 406. A first support plate 5 and a second support plate 6 are fixedly connected to one side of the exhaust pipe 3. A motor 7 is fixedly installed on one side of the first support plate 5, and a threaded rod 8 is fixedly connected to the output end of the motor 7. The surface of the threaded rod 8 is rotatably connected to the inner cavity of the first support plate 5 and the second support plate 6. A threaded hole 9 is provided on one side of the second slider 404, and the inner wall of the threaded hole 9 is threadedly connected to the surface of the threaded rod 8. The housing 1 of this adjustable testing equipment mainly supports and connects the testing circuit. The heat and harmful gases generated during testing inside the outer casing 1 are discharged through two exhaust pipes 3. The motor 7 can be considered the drive source of the adjustment mechanism 4. The motor 7 is supported by the first support plate 5 and the second support plate 6. The motor 7 can drive the threaded rod 8 to rotate along the second support plate 6. The folding plate 401 in the adjustment mechanism 4 can retract or extend along the inner wall port of the exhaust pipe 3. When the folding plate 401 retracts, it opens the port of the exhaust pipe 3. Continuous retraction of the folding plate 401 increases the open area of ​​the exhaust pipe 3 port, achieving adjustment of different areas. While 401 is raised and lowered, the connecting plate 402 is raised and lowered synchronously. The first slider 403 on one side of the connecting plate 402 can slide along the first slide groove 405 to improve the stability of the folding plate 401 when it is retracted. The second slider 404 fixes the two sets of connecting plates 402 into one piece. The second slider 404 can slide along the second slide groove 406 to further improve the stability of the folding plate 401 when it is raised and lowered. Furthermore, through the threaded hole 9 on the second slider 404 and the threaded rod 8, the second slider 404, the connecting plate 402 and the folding plate 401 are automatically raised and lowered when the threaded rod 8 rotates, ensuring the convenience of adjustment.

[0026] Reference Figures 2 to 5A filter membrane 10 is fixedly connected to one side of the connecting plate 402, and a coil spring 11 is fixedly connected to one end of the filter membrane 10. A third support plate 12 is fixedly connected to the top of the outer shell 1. There are two third support plates 12. A connecting roller 13 is rotatably connected to the inner cavity of the third support plate 12. The other end of the coil spring 11 is fixedly connected to the surface of the connecting roller 13. A through groove 14 is opened on one side of the exhaust pipe 3. The surface of the filter membrane 10 is attached to the inner wall of the through groove 14. The filter membrane 10 can be a mixed base membrane of activated carbon. When the folding plate 401 is raised and lowered... While folding, the connecting plate 402 is raised and lowered. As the connecting plate 402 is raised and lowered, the filter membrane 10 is pulled through the through groove 14 and extended to the air outlet area of ​​the exhaust pipe 3, thereby filtering the exhaust air through the filter membrane 10. The filter membrane 10 and the coil spring 11 are integrally formed and fixedly connected to the connecting roller 13 through the coil spring 11. When the filter membrane 10 is extended, it can drive the connecting roller 13 to rotate along the third support plate 12, and the coil spring 11 can be tightened along the connecting roller 13. When the folding plate 401 is reset, the coil spring 11 releases to help the filter membrane 10 rewind, ensuring the winding efficiency.

[0027] Reference Figure 4 and Figure 5 A gear 15 is fixedly connected to one end of the connecting roller 13, and a toothed plate 16 is fixedly connected to one side of the first slider 403. The teeth of the toothed plate 16 and the teeth of the gear 15 mesh with each other. Through the gear 15 and the toothed plate 16, the gear 15 and the connecting roller 13 are coaxially fixedly connected. When the connecting roller 13 rotates, it drives the gear 15 to rotate synchronously. The toothed plate 16 and the first slider 403 are fixedly connected. When the folding plate 401 raises and lowers to adjust the exhaust pipe 3 port, it drives the toothed plate 16 to rise and fall. When the exhaust pipe 3 port is closed, the teeth of the toothed plate 16 and the teeth of the gear 15 mesh with each other, thereby realizing the mutual self-locking of the folding plate 401 and the connecting roller 13, ensuring the firmness between the structures.

[0028] Working Principle: Heat and harmful gases generated during testing inside the outer casing 1 are exhausted through two exhaust pipes 3. The motor 7 serves as the drive source for the adjustment mechanism 4, supported by a first support plate 5 and a second support plate 6. The motor 7 drives a threaded rod 8 to rotate along the second support plate 6. The folding plate 401 in the adjustment mechanism 4 can retract or extend along the inner wall of the exhaust pipe 3. When the folding plate 401 retracts, it opens the port of the exhaust pipe 3. Continuous retraction of the folding plate 401 increases the open area of ​​the exhaust pipe 3 port, achieving adjustment of different areas. Simultaneously, the folding plate 401 raises and lowers, driving the connecting plate 402 to rise and fall synchronously. A first slider 403 on one side of the connecting plate 402 slides along a first groove 405 to improve the stability of the folding plate 401's retraction. A second slider 404 fixes the two sets of connecting plates 402 together, and slides along a second groove 406. To further improve the stability of the lifting and lowering of the folding plate 401, the threaded hole 9 on the second slider 404 cooperates with the threaded rod 8. When the threaded rod 8 rotates, the second slider 404, the connecting plate 402, and the folding plate 401 automatically lift and lower, ensuring convenient adjustment. The filter membrane 10 can be a mixed base membrane of activated carbon. When the folding plate 401 lifts and folds, it drives the connecting plate 402 to lift and lower. When the connecting plate 402 lifts and lowers, it pulls the filter membrane 10 through the through groove 14 to extend to the air outlet area of ​​the exhaust pipe 3, thereby filtering the exhaust air through the filter membrane 10. The filter membrane 10 and the coil spring 11 are integrally formed and fixedly connected to the connecting roller 13 through the coil spring 11. When the filter membrane 10 extends, it can drive the connecting roller 13 to rotate along the third support plate 12, and the coil spring 11 can be tightened along the connecting roller 13. When the folding plate 401 is reset, the coil spring 11 releases to help the filter membrane 10 rewind, ensuring winding efficiency.
