A threaded hole 83 is opened on the surface of the sliding rod 6. The surface of the threaded rod 82 is threadedly connected to the inner wall of the threaded hole 83.

[0024] As a technical optimization solution of the utility model, by setting the adjustment component 8, the servo motor 81 can effectively drive the threaded rod 82 to rotate, and then the threaded rod 82 drives the sliding rod 6 to slide forward through the threaded hole 83, so that the sliding rod 6 drives the cooling fan 7 to be adjusted to the top of the test piece.

[0025] refer to Figure 1 and Figure 3 The auxiliary cleaning assembly 9 includes a movable plate 91, which is fixedly connected to both sides of the top of the sample rack 4. The inner wall of the movable plate 91 is slidably connected with a connecting plate 92, and the bottom of the connecting plate 92 is fixedly connected with a scraper 93, and the bottom of the scraper 93 contacts the top of the sample rack 4.

[0026] As a technical optimization solution of the utility model, by setting up an auxiliary cleaning component 9, the connecting plate 92 can effectively slide on the inner wall of the movable plate 91, and the scraper 93 can be driven to move forward by the connecting plate 92, so that the scraper 93 can scrape the surface of the sample rack 4, thereby avoiding the sample remaining on the surface of the sample rack 4, which makes it difficult for the user to clean, and can achieve the effect of the auxiliary cleaning function.

[0027] refer to Figure 1 A control box 10 is fixedly connected to the left side of the front side of the box body 1, and the control box 10 is electrically connected to the cooling fan 7 through a wire.

[0028] As a technical optimization solution of the present invention, by providing a control box 10 , the control box 10 can effectively control the cooling fan 7 , making it convenient for the user to adjust the rotation speed of the cooling fan 7 .

The warning light 15 can facilitate the user to observe the adjustment position of the cooling fan 7 to prevent the user from colliding with the cooling fan 7.

[0035] The working principle and use process of the utility model are as follows: when in use, the user first puts the sample into the top of the sample rack 4, and dries the sample through the box 1. When the sample is dried, the user slides the sample rack 4 forward through the slide groove 2 and the slide block 3. Then the user drives the threaded rod 82 to rotate through the servo motor 81. Then the threaded rod 82 drives the sliding rod 6 to slide forward through the threaded hole 83, so that the sliding rod 6 drives the cooling fan 7 to move forward. The cooling fan 7 is adjusted to the top of the sample, and then the cooling fan 7 is controlled by the control box 10. The heat dissipation fan 7 can perform heat dissipation treatment on the sample and the sample rack 4, which can increase the cooling speed of the sample and the sample rack 4, avoid the sample and the sample rack 4 from causing burns to the user's hands, and achieve the effect of protective function. When the sample remains on the sample rack 4, the user can use the connecting rod 13 and the pull ring 14 in combination, so that the user can pull the movable plate 91 through the pull ring 14 to move, so that the movable plate 91 can drive the scraper 93 to scrape the surface of the sample rack 4, which can achieve the effect of easy cleaning and avoid the sample residue on the surface of the sample rack 4, which makes it difficult for the user to clean.

[0036] In summary, the protective structure of the constant temperature drying box, by setting the sliding plate 5, the sliding rod 6, the cooling fan 7 and the adjusting component 8, can effectively enable the adjusting component 8 to drive the sliding rod 6 on the inner wall of the sliding plate 5 to move forward, so that the sliding rod 6 drives the cooling fan 7 to move to the top of the sample, and the cooling fan 7 can dissipate heat for the sample and the sample rack 4, thereby solving the problem that due to the lack of a protective structure, after the sample rack drives the sample to move forward, the surface temperature of the sample and the sample rack is too high, resulting in burns when the user takes the sample with his hands, thereby posing a certain risk.
