[0006] A movable support is provided at the lower opening of the guide frame. The movable support can move in the guide frame to switch its own position. The movable support is provided with a test tube positioning structure that can move synchronously with the movable support. When the movable support moves up to the limit, the test tube positioning structure extends above the second bearing net through the second bearing net.

[0007] Furthermore, the test tube positioning structure includes a plurality of bases arranged on the inner side of the movable support, the plurality of bases are connected by connecting rods, and the tops of the plurality of bases are provided with limiting sleeves capable of accommodating the test tubes.

[0008] Furthermore, the movable support is provided with an alignment bar, and the alignment bar is located on the inner side of the guide frame. When the movable support moves up to a limit height, the alignment bar is exposed from the guide frame.

[0009] The alignment strips are provided with guide rods, the guide frames are provided with guide channels that can accommodate the movement of the guide rods, the guide rods pass through the guide channels and extend to the outside of the guide frames. The guide rods are provided with threaded portions, and the threaded portions are provided with detachable limiting screw sleeves.

[0010] Furthermore, an anti-skid pad is provided at one end of the limiting screw sleeve close to the guide frame. When the limiting screw sleeve moves to a limit extent toward the guide frame, the anti-skid pad is pressed against the surface of the guide frame.

[0011] Furthermore, a limiting channel is opened at the center position of the alignment strip, and the limiting channel can pass through the surface of the second bearing net as the movable support moves. When the movable support moves up to the limit, the second bearing net abuts against the inner bottom wall of the limiting channel.

[0012] In summary, the technical effects and advantages of the utility model are:

[0013] The utility model can position the test tubes loaded with chemical samples to be tested according to different work requirements through the test tube positioning structure that can switch positions, so that the tray can be flexibly adjusted according to work requirements. During the drying process, the test tubes can be erected on the tray, saving the space occupied by the test tubes during the drying process. Multiple test tubes can be accommodated at the same time, so as to facilitate the drying operation of chemical samples in multiple test tubes. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0021] 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.

[0022] Example 1: Reference Figure 1-5 The electric constant temperature drying oven tray shown comprises an outer frame 1 and a first carrier net 2 arranged on the outer frame 1, a guide frame 3 is embedded on the first carrier net 2, and a second carrier net 4 is arranged at the same level as the first carrier net 2 at the upper opening of the guide frame 3. Since the electric constant temperature drying oven is mostly provided with a plurality of trays arranged in parallel, the combination of the first carrier net 2 and the second carrier net 4 can not only carry the sample box, but also make the dry air flow in the box flow smoothly, so that the plurality of samples to be dried that are distributed in parallel inside the electric constant temperature drying oven can be dried evenly and quickly.

[0023] Depending on the work requirements, if it is necessary to dry chemical samples in multiple test tubes, the first carrier net 2 and the second carrier net 4 can carry ordinary sample boxes, but cannot fix the test tubes, and the stability of the test tubes cannot be guaranteed. In order to avoid this phenomenon, a movable support 5 is provided at the lower opening of the guide frame 3. The movable support 5 can be located in the guide frame 3 and move to switch its own position. The movable support 5 is provided with a test tube positioning structure that can move synchronously with it. When the movable support 5 moves up to the limit, the test tube positioning structure passes through the second carrier net 4 and extends above it.

[0024] The test tube positioning structure with switchable positions can be used to position the test tubes loaded with chemical samples to be tested, so that the tray can be flexibly adjusted according to work requirements. During the drying process, the test tubes can be placed upright on the tray, saving the space occupied by the test tubes during the drying process.

[0025] like Figure 3-5As shown, the test tube positioning structure includes a plurality of bases 7 disposed inside the movable support 5, the plurality of bases 7 are connected by connecting rods 6, and the tops of the plurality of bases 7 are provided with limiting sleeves 8 capable of accommodating the test tubes. When the test tube positioning structure passes through the second carrying net 4 and extends to the top thereof, the test tubes can be placed in the limiting sleeves 8, and the combination of the plurality of limiting sleeves 8 and the plurality of bases 7 can accommodate a plurality of test tubes at the same time, so as to facilitate the drying operation of the chemical samples in the plurality of test tubes.

[0026] Embodiment 2:

[0027] like Figure 3-5 As shown, the movable support 5 is provided with an alignment bar 9, and the alignment bar 9 is located on the inner side of the guide frame 3. When the movable support 5 moves up to the limit height, the alignment bar 9 is exposed from the guide frame 3 as the movable support 5 moves up.

[0028] A guide rod 11 is provided on the alignment strip 9, and a guide channel 12 for accommodating the movement of the guide rod 11 is opened on the guide frame 3. A threaded portion is provided on the portion of the guide rod 11 that passes through the guide channel 12 and extends to the outside of the guide frame 3. When the movable support 5 moves up to the limit, in order to maintain the stability of the movable support 5, a detachable limiting screw sleeve 13 is provided on the threaded portion, which can fasten the guide rod 11 to the guide frame 3.

[0029] like Figure 4 As shown, in order to improve the tightness of the connection between the limiting screw sleeve 13 and the guide frame 3, the mobile support 5, the alignment bar 9 and the test tube positioning structure are prevented from deflecting and sliding down. An anti-skid pad 14 is provided at one end of the limiting screw sleeve 13 close to the guide frame 3. The anti-skid pad 14 is made of elastic anti-skid material. When the limiting screw sleeve 13 moves to the limit height toward the guide frame 3, the anti-skid pad 14 is pressed against the surface of the guide frame 3. The tightness of the connection between the limiting screw sleeve 13 and the guide frame 3 can be improved, and the deviation and sliding down of the test tube positioning structure caused by the loosening of the limiting screw sleeve 13 can be effectively avoided.

[0030] like Figure 4 As shown, in order to prevent the movable support 5 from moving excessively during the upward movement and causing the movable support 5 to separate from the guide frame 3, a limiting channel 10 is opened at the center position of the alignment strip 9. The limiting channel 10 can pass through the surface of the second bearing net 4 as the movable support 5 moves. The second bearing net 4 can limit the moving stroke of the movable support 5. When the movable support 5 moves up to the limit height, the second bearing net 4 abuts against the inner bottom wall of the limiting channel 10.

[0031] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
