[0036] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0037] Reference Figure 1 , Figure 2 and Figure 3 The utility model provides an embodiment of an expansion reagent curing box, comprising a box body 1, wherein slide grooves 3 are provided on the left and right sides of the interior of the box body 1, a U-shaped frame 4 is arranged inside the box body 1, and the left and right sides of the U-shaped frame 4 are respectively slidably connected with the corresponding interior of the slide groove 3, an open groove 5 is provided on the rear side of the interior of the U-shaped frame 4, and a bidirectional screw rod 6 is rotatably connected inside the open groove 5, and the upper and lower sides of the outer wall of the bidirectional screw rod 6 are threadedly connected with a movable plate 7, a fixed plate 8 is fixedly connected to the middle part of the inner side of the U-shaped frame 4, and a driven bevel gear 9 is fixedly connected to the middle and upper part of the outer wall of the bidirectional screw rod 6, a U-shaped plate 10 is fixedly connected to the middle and upper part of the inner rear end of the U-shaped frame 4, and a rotating rod 11 is rotatably connected to the front side of the U-shaped plate 10, and the rear end of the rotating rod 11 penetrates the U-shaped plate 10 and is fixedly connected with an active bevel gear 12, and the active bevel gear 12 is meshed with the driven bevel gear 9, and a recycling mechanism 2 is arranged on the middle and lower part of the inner side of the box body 1, and one side of the two movable plates 7 is slidably connected to the interior of the open groove 5;

[0038] Specifically, rotating the rotating rod 11 can drive the active bevel gear 12 to start rotating. Since the driven bevel gear 9 is tightly meshed with the active bevel gear 12, the driven bevel gear 9 will also rotate. As the driven bevel gear 9 rotates, it will further drive the bidirectional screw 6 to rotate. When the bidirectional screw 6 rotates, the movable plate 7 will move toward the middle, and the spacing between the movable plate 7 and the fixed plate 8 can be accurately adjusted. This adjustment mechanism allows enough space between each specimen, avoiding mutual interference and collision between the specimens. The existence of this space is crucial for the maintenance of the specimens, because it ensures that the specimens can obtain sufficient oxygen and moisture during the maintenance process, avoiding insufficient maintenance due to excessive crowding, thereby ensuring that the specimens are fully maintained, and then ensuring the accuracy of the test results.

[0039] Reference Figure 1 and Figure 2 The recycling mechanism 2 includes a collecting box 201, which is fixedly connected to the middle and lower part of the inner side of the box body 1, and a filter screen 202 is fixedly connected to the inner side of the collecting box 201. The tops of the movable plate 7 and the fixed plate 8 are evenly spaced with a plurality of square grooves 203. The recycling mechanism 2 also includes a liquid inlet 204, which is connected to the top of the box body 1, and the bottom of the collecting box 201 is connected to a liquid outlet 205. The middle and lower parts of the liquid outlet 205 penetrate the box body 1, and the outer sides of the liquid inlet 204 and the liquid outlet 205 that are far away are both threadedly connected with a sealing cover 206;

[0040] Specifically, after the maintenance work is completed, the sealing cover 206 at the bottom of the liquid outlet 205 is first loosened. This step is crucial because it provides a channel for the recycling of water resources. The design of the sealing cover 206 cleverly ensures that the water source in the box 1 can remain clean during the maintenance period to avoid external pollution. At the same time, its loosening operation is also very convenient, so that the staff can easily perform subsequent operations. The water source after the maintenance work will then be filtered through the filter screen 202, which is used to remove impurities and particulate matter in the water source to ensure the safety and cleanliness of the water quality. Through the filtering effect of the filter screen 202, we can effectively remove suspended matter, bacteria and other harmful substances in the water, so that the water resources are further purified, and the filtered water source will be discharged through the liquid outlet 205, and the water source in the box 1 can be recycled, thereby effectively saving water resources and reducing waste.

[0041] Reference Figure 1 A door 13 is provided at the front side of the box body 1, and a shaft 14 is provided at the upper and lower sides of the right end of the door 13. The door 13 is rotatably connected to the right end of the box body 1 through the shaft 14. A groove 15 is provided at the left side of the front end of the door 13, and an observation window 16 is provided at the middle of the front end of the door 13;

[0042] Specifically, the chamber door 13 can be opened conveniently through the groove 15 to take out the tested specimen.

[0043] Reference Figure 1 A control panel 18 is fixedly connected to the left side of the front end of the box body 1, and a temperature and humidity sensor 19 is fixedly connected to the upper middle part of the front side of the control panel 18. The control panel 18 is electrically connected to the temperature and humidity sensor 19;

[0044] Specifically, the operation of the temperature and humidity sensor 19 can be controlled through the control panel 18 .

[0045] Reference Figure 1 Universal wheels 17 are fixedly connected to the four corners of the bottom of the box body 1;

[0046] Specifically, the device can be easily moved by the universal wheels 17.

[0047] Working principle: When using the device, the box door 13 can be opened through the groove 15, and then the U-shaped frame 4 is pulled out, and the test piece to be tested is placed on the fixed plate 8 and the movable plate 7 in turn. At this time, the rotating rod 11 can drive the active bevel gear 12 to rotate, and the driven bevel gear 9 will also rotate with it due to the meshing with the active bevel gear 12, thereby driving the bidirectional screw rod 6 to rotate. At this time, the movable plate 7 on the bidirectional screw rod 6 will move to the middle. The distance between the movable plate 7 and the fixed plate 8 can be adjusted according to the size of the test piece, so that there is enough space between each test piece, so that the test piece can be fully maintained. Protection can ensure the accuracy of the test results and meet the needs of users. Then, the U-shaped frame 4 is pushed back into the box body 1, and then the box door 13 is closed, and water is injected into the box body 1 through the liquid inlet 204. At this time, the test piece can be kept within the range to be detected through the temperature and humidity sensor 19, and the sealing cover 206 at the bottom of the liquid outlet 205 is loosened after the maintenance work is completed. At this time, the water source after the maintenance work will be filtered through the filter screen 202, and the filtered water source will be discharged through the liquid outlet 205. The water source in the box body 1 can be recycled, thereby improving the practicality of the device.
