DETAILED DESCRIPTION

[0017] The present invention will be further described below with reference to the accompanying drawings.

[0018] Please refer to the following: Figs. 1-3 The dustproof device of a dustproof test chamber shown includes a test chamber body 1, a sealed door 2, a storage frame, and a diversion grid 3. U-shaped frames 4 are fixedly connected to both sides of the storage frame that are far apart from each other. A steel plate 5 contacts the inside of the U-shaped frame 4. The contact between the U-shaped frame 4 and the steel plate 5 provides support for the support plate 6, while reducing the number of connecting structures and decreasing the windproof effect of the steel plate 5. An adjusting rod 17 is threadedly connected to one side of the U-shaped frame 4. Rotating the adjusting rod 17 causes a pressure plate 18 to press against the steel plate 5, improving the stability of the steel plate 5 and the support plate 6. A pressure plate 18 is rotatably connected to one side of the adjusting rod 17. A support plate 6 is fixedly connected between two adjacent steel plates 5 in contact with the steel plate 5. A drive motor 7 is fixedly connected to the bottom end of the support plate 6. The drive motor 7 has a built-in driver program and can be purchased as needed. The drive motor 7 drives the rotating rod to rotate, which can cause the turntable 8 and the support bar 9 to rotate the material to be inspected. A rotating rod is fixedly connected to the output end of the drive motor 7. A turntable 8 is fixedly connected to the upper end of the rotating rod. Support bars 9 are fixedly connected to the four sides of the upper end of the turntable 8. Through holes 10 are evenly opened on the support plate 6 and the steel plate 5. By setting through holes 10, the gap between the object to be tested and the support plate 6 is reduced, and dust accumulation is reduced.

[0019] The bottom end of the support plate 6 is fixedly connected to a guide cover 11. The bottom end of the guide cover 11 has a conical structure. By setting the guide cover 11, dust contact with the drive motor 7 is reduced, and a guiding effect is provided.

[0020] The support plate 6 is rotatably connected to a connecting sleeve 12, which is fixedly connected to the outside of the rotating rod. Each of the four mutually distant sides of the connecting sleeve 12 is fixedly connected to a scraper 13. By setting the connecting sleeve 12 and the scraper 13, the upper side of the support plate 6 can be cleaned.

[0021] The support plate 6 has a circular groove 14, a bracket is fixedly connected in the circular groove 14, and a supplementary fan 15 is rotatably connected in the bracket. By setting the supplementary fan 15, the supplementary air supply effect on the upper side of the support plate 6 can be increased, and the gap between the object to be tested and the support plate 6 can be reduced.

[0022] The bracket has filters 16 on both the top and bottom sides. The filters 16 are fixedly connected in the circular groove 14. By setting the filters 16, the amount of dust entering the circular groove 14 can be reduced.

[0023] Working principle: the object to be detected is placed on the support strip 9 on the upper side of the support plate 6, and the pressing plate 18 is driven by rotating the adjusting rod 17 to extrude the steel plate 5, promote the stability of the steel plate 5 and the support plate 6, then close the sealing door 2, the inside of the test box 1 runs, the dust circulates in the storage frame, then the driving motor 7 drives the rotating disc 8 and the support strip 9 to rotate, and promotes the rotation of the material to be tested, reduces the vortex area caused by the protrusions and depressions on the material to be tested in contact with the airflow, at the same time the scraper 13 lifts the dust on the support plate 6, at this time the air supplement fan 15 rotates, reduces the gap between the support plate 6 and the material to be tested, further reduces the dust deposition, greatly improves the accuracy of the test.
