[0021] Preferably, the base assembly further includes a touch screen for displaying parameters of the test tubes in the test tube slot.
[0022] Specifically, by observing the test tube parameters through the touchscreen, one can quickly and comprehensively grasp the data of various aspects of the test tube.
[0023] Compared with the prior art, the advantages of this utility model are:
[0024] This invention utilizes a heating component that is detachably connected to the main body to achieve rapid heating of the test tube. Since the heating component includes a fixing part and several heating plates, and the heating plates are arranged along the axial direction of the test tube groove and are located in multiple places on the main body, the heating rate is accelerated while the entire main body is heated evenly. Even heating of the main body means that the test tube groove is heated evenly. In addition, the structure of the fixing part of the heating component cooperating with the fixing block makes the installation between the heating component and the main body more convenient.

[0031] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.
[0032] like Figures 1-6 As shown, a test tube heating rack with uniform heating includes a test tube rack assembly and a base assembly 20. The test tube rack assembly includes a body 11, a plurality of test tube slots 12, and a heating component for heating test tubes 80 placed in the test tube slots 12. The heating component includes a heating circuit and a heating element 30. The heating element 30 is detachably connected to the body 11. The heating element 30 includes a heating part and a fixing part 32. The fixing part 32 is formed by connecting a plurality of arc-shaped plates and a flat plate. The heating part includes a plurality of heating plates 31. Each heating plate 31 is distributed at various locations on the body 11 for heating each test tube slot 12. Each heating plate 31 is separated from each other, fixed on the fixing part 32, and extends along the body 11. Its extension direction is consistent with the axial direction of the test tube slot 12. The body 11 is provided with slots adapted to the heating plates 31.
[0033] Compared to traditional water bath heating, heating using a heating component has the advantage of rapid temperature rise. In this embodiment, the heating component 30 includes a fixing part 32 and several heating plates 31. The fixing part 32 is composed of several arc-shaped plates and flat plates connected together, and the heating plates 31 are all fixed on the fixing part 32. At the same time, the heating plates 31 extend along the axial direction of the test tube groove 12, that is, heating plates 31 are provided at multiple positions on the body 11, which allows the entire body 11 to be effectively heated by the heating component 30.
[0034] It also includes a fixing block 40, which is used to cooperate with the fixing part 32 to fix the heating member 30 to the body 11.
[0035] Since the heating element 30 is detachably connected to the body 11, and the structure of the fixing block 40 cooperating with the fixing part 32 makes the connection between the heating element 30 and the body 11 more stable.
[0036] It also includes a control component, which includes a temperature sensor 52 for detecting the temperature of the test tubes 80 in each test tube 12, a chip 51 for memorizing the required temperature of the test tubes 80 in each test tube 12, and a controller for controlling the temperature of the test tubes in each test tube 12 to be at the corresponding required temperature.
[0037] The heating temperature in each test tube trough 12 can be precisely controlled by the control components. In actual use, the test tube 80 can be placed in the corresponding test tube trough 12 according to the required temperature. This not only makes the temperature control more precise but also effectively reduces the intensity of manual labor.
[0038] The heating circuit includes an over-temperature protector 60, which activates to disconnect the heating circuit when the temperature sensor 52 detects that the temperature of the test tube 80 exceeds the required temperature.
[0039] To prevent the sample inside the test tube 80 from being damaged by excessive temperature, the structure of the over-temperature protector 60 is appropriately designed.
[0040] The test tube rack assembly is rotatably connected to the base assembly 20. The base assembly 20 or the test tube rack assembly is provided with a rotating shaft 70, and the test tube rack assembly or the base assembly 20 is provided with a rotating groove adapted to the rotating shaft 70. A stop is also provided on the inner wall of the rotating groove, and the test tube rack assembly or the base assembly 20 is provided with a component to control the position of the stop. When the stop protrudes from the inner wall of the rotating groove, the test tube rack assembly and the base assembly 20 cannot rotate relative to each other.
[0041] The test tube rack assembly and the base assembly 20 are detachably connected, and during installation, it is only necessary to ensure that the length and width of the two correspond.
[0042] Either of these two installation methods will make the installation between the test tube rack assembly and the base assembly 20 more convenient.
[0043] A heat insulation plate 15 is provided on the surface of the test tube rack assembly that contacts the base assembly 20.
[0044] The structure of the heat insulation plate 15 can effectively reduce the heat loss of the test tube rack assembly, which is more conducive to maintaining the temperature stability of the test tubes 80 in the test tube tank 12.
[0045] The test tube rack assembly also includes a transparent heat insulation cover 13, and each test tube slot 12 is provided with a slot 14 along the axial direction. The state of the test tubes 80 in the test tube slot 12 can be directly observed through the transparent heat insulation cover 13 and the slot 14.
[0046] The transparent heat shield 13 has a heat insulation function and can also effectively reduce the heat loss in the test tube trough 12, further ensuring the temperature stability of the test tube 80. The transparent heat shield 13 is made of transparent material, so the test tube 80 in the test tube trough 12 can be observed directly through the transparent heat shield 13.
[0047] The base assembly 20 also includes a touch screen 21, which is used to display the parameters of the test tubes 80 in the test tube tank 12.
[0048] By observing the parameters of test tube 80 through the touch screen 21, one can quickly and comprehensively grasp the data of test tube 80 in all aspects.
