However, this structure still has the problems of slow heating and limited test tube specifications. Utility Model Content

[0005] In order to solve the problems existing in the prior art, the utility model provides a heating test tube rack.

[0007] Specifically, for a heated test tube rack, the size of the test tube slot is usually adapted to the size of the test tube placed therein. The heating device is attached to the slot wall of the test tube slot, and most of the heat generated by the heating device is directly used to heat the test tube, effectively improving the efficiency of test tube heating. At the same time, the heating device is set as a curved heating plate adapted to the slot wall, so that the test tube can be heated simultaneously at multiple angles and directions, achieving more uniform and rapid heating of the test tube.

[0008] Preferably, the curved heating plate is a plurality of S-shaped heating plates, each S-shaped heating plate is fitted with the outer groove wall of two adjacent test tube grooves, and the S-shaped heating plates are interconnected / integrally formed to form a curved heating plate.

[0015] Specifically, during the heating process of the test tube, it may be necessary to observe the test tube or the contents of the test tube. Therefore, it is appropriate to set an observation hole in each test tube slot, and it is preferred to set the observation hole to be larger along the axial direction of the test tube slot.

[0016] Preferably, it further comprises an outer shell, which is sleeved on the outer side of the main body, and the outer shell is transparent and has a heat preservation function.

[0017] Specifically, the structure of opening an observation hole will cause a certain degree of heat loss, thereby affecting the heating efficiency. Therefore, it is appropriate to set up a structure with a shell having a heat-insulating function. At the same time, in order to prevent the shell from blocking the observation hole, it is appropriate to set the shell to be transparent. Under normal circumstances, the shell can be directly made of a material with transparent and heat-insulating functions.

[0018] Preferably, it further comprises a base, which is detachably connected to the body, and is provided with a positioning member, a connecting member and a conducting member.

[0032] like Figure 1-3 As shown, a heated test tube rack includes a main body 10 with a plurality of test tube slots 20. The test tube slots 20 have openings. At least a portion of the slot walls of the test tube slots 20 are provided with heating devices. The heating devices are in contact with the slot walls of the test tube slots 20. The heating devices include curved heating plates 30. The curved surface of the curved heating plates 30 is at least partially adapted to the shape of at least a portion of the slot walls of the test tube slots 20.

[0033] For a heated test tube rack, the size of the test tube slot 20 is usually adapted to the size of the test tube placed therein. The heating device is attached to the slot wall of the test tube slot 20. Most of the heat generated by the heating device is directly used to heat the test tube, effectively improving the efficiency of test tube heating. At the same time, the heating device is set as a curved heating plate 30 adapted to the slot wall, so that the test tube can be heated simultaneously at multiple angles and directions, achieving more uniform and rapid heating of the test tube.

[0034] The curved heating plate 30 is a plurality of S-shaped heating plates, each of which is fitted with the outer groove wall of two adjacent test tube grooves 20 , and the S-shaped heating plates are interconnected / integrally formed to form the curved heating plate 30 .

[0035] A curved heating plate 30 is formed by connecting a number of S-shaped heating plates to each other / integrally forming a curved heating plate, and each S-shaped heating plate is in contact with the outer groove walls of two adjacent test tube grooves 20. This structure allows one curved heating plate 30 to be in contact with the groove walls of multiple test tube grooves 20, facilitating the unified control of the heating temperature of multiple test tubes and ensuring the consistency of various heating data of the test tubes heated in the same batch.

[0036] The test tube slots 20 are arranged in a rectangular array, and the number of curved heating plates 30 is equal to the number of rows or columns of the rectangular array; a handle 40 is provided at the central axis of the top of the body 10, and the long side of the handle 40 is parallel to the long side or short side of the rectangular array.

[0037] The test tube slots 20 are arranged in a rectangular array, so that the test tube slots 20 in the same row / column are all in contact with the curved surfaces at different positions of the same curved heating plate 30; the structure of the handle 40 facilitates the transportation and installation of the test tube rack. The handle 40 is arranged at the central axis of the top of the body 10 to ensure that the test tube rack can be smoothly transferred or installed.

[0038] The handle 40 is a hidden handle.

[0040] The main body 10 is provided with a plurality of observation holes 11 for observing the status of the test tubes, and the observation holes 11 correspond to the test tube slots 20 one by one.

[0041] During the heating process of the test tube, it may be necessary to observe the test tube or the contents of the test tube. Therefore, it is appropriate to set an observation hole 11 in each test tube slot 20, and it is preferred to set the observation hole 11 larger along the axial direction of the test tube slot 20.

[0042] The main body 10 further includes a shell 50 which is sleeved on the outside of the main body 10 . The shell 50 is transparent and has a heat-insulating function.

[0043] The structure of opening the observation hole 11 will cause a certain degree of heat loss, thereby affecting the heating efficiency. Therefore, it is appropriate to set up a structure of the shell 50 with a heat-insulating function. At the same time, in order to prevent the shell 50 from blocking the observation hole 11, it is appropriate to set the shell 50 to be transparent. Under normal circumstances, the shell 50 can be directly made of a material with transparent and heat-insulating functions.

[0044] The main body 10 further includes a base 60 , which is detachably connected to the main body 10 , and is provided with a positioning member, a connecting member and a conducting member.
