[0029] like Figure 1-5As shown, the utility model provides a test tube graphite heating seat, including a graphite heating seat 1, a transfer bracket 2 and an experimental test tube 3. The graphite heating seat 1 is provided with a plurality of test tube slots 101 in an array for inserting the test tube and heating it with the graphite heating seat 1; the experimental test tube 3 includes a main body 31, a step 32 and an extension tube portion 33, wherein the extension tube portion 33 is arranged at the top of the main body 31, and the step 32 is arranged outside the top of the main body 31. The step 32 can limit the length of the insertion below the transfer bracket 2, and the step 32 can be used to control the injection amount of the solvent, which is controlled near the step 32, and the extension tube portion 33 is used as a boiling accommodation space, thereby increasing the boiling height, facilitating the observation of the inside of the test tube, and effectively preventing the solution from splashing out during boiling; the transfer bracket 2 It includes a flat support plate 21 and a plurality of support rods 22. The flat support plate 21 is provided with a plurality of insertion holes 201, and the insertion holes 201 correspond to the test tube slots 101 one by one. The step 32 is used to be placed on the top of the flat support plate 21. The experimental test tube 3 is first inserted into the insertion hole 201 and then inserted into the test tube slot 101. Moreover, when inserted, the step 32 is placed on the flat support plate 21 to support the experimental test tube 3. The support rod 22 is arranged at the bottom of the flat support plate 21 and is plugged into the graphite heating seat 1. By plugging in, it is convenient to disassemble the transfer bracket 2 from the graphite heating seat 1, and the step 32 is used as the support structure for the experimental test tube 3 and the transfer bracket 2. All the experimental test tubes 3 on it can be transported and transferred by the transfer bracket 2, thereby improving the convenience of test tube transfer.

[0030] It can be understood that the test tube graphite heating seat provides a matching transfer bracket 2 on the basis of the basic graphite heating function, for the test tube to be inserted and provide support for the test tube, and can quickly dock all the test tubes at one time and insert them into the test tube slot 101 on the graphite heating seat 1, and can also quickly lift all the test tubes at one time and transfer them. The test tube also adopts a two-section combination of a main body 31 and an extension tube part 33, with a step 32 as a dividing line, the solution is accommodated below, and the above is used as a boiling space to avoid splashing when the solvent boils, and the step 32 facilitates the test tube to be placed on the transfer bracket 2 and transferred with the transfer bracket 2.

[0031] In this embodiment, refer to Figure 2In order to facilitate the insertion and assembly of the transfer bracket 2 and the graphite heating seat 1, and the transfer bracket 2 can also be used as a test tube rack to place test tubes, the support rod 22 includes a rod body 221 and a pad 222, the outer diameter of the pad 222 is larger than the outer diameter of the rod body 221, and the pad 222 is detachably arranged at the bottom end of the rod body 221, as a bottom support placed on the desktop, and can be replaced after wear to avoid the flat support plate 21 from tilting during insertion. The graphite heating seat 1 includes a heating seat body 11 and a plurality of support seats 12, a plurality of The support seat 12 is arranged on the outside of the heating seat body 11, and the pad foot 222 is plugged into the support seat 12 one by one. The support seat 12 is located near the bottom of the heating seat body 11, and the height of the seat body provides the sinking height of the support rod 22, so that the flat support plate 21 is close to the top of the graphite heating seat 1, so that the experimental test tube 3 placed on it is inserted downward into the test tube groove 101, and the entire transfer bracket 2 can be positioned by plugging the support rod 22 into the support seat 12, and correspondingly, the experimental test tube 3 is inserted into the test tube groove 101.

[0032] There are four support seats 12 and four support rods 22 , which are evenly distributed on the periphery of the graphite heating seat 1 , so as to achieve a stable support effect.

[0033] Further, to improve stability during transfer and placement of test tubes, see Figure 3 The transfer bracket 2 also includes an auxiliary frame 23, which is located below the flat support plate 21 and is fitted with several of the support rods 22. The auxiliary frame 23 is provided with several positioning holes 2303, and the positioning holes 2303 correspond to the insertion holes 201 one by one. When the experimental test tube 3 is inserted, it will pass through the insertion hole 201 and the positioning holes 2303 in sequence. The up and down movement of the auxiliary frame 23 is guided by the support rod 22. The auxiliary frame 23 is slidably connected to the support rod 22. When the flat support plate 21 is lifted, due to the action of gravity, the auxiliary frame 23 will automatically slide downward along the support rod 22 and slide to the top of the pad 222 to be limited. At this position, the auxiliary frame 23 serves as an auxiliary support part close to the bottom end of the experimental test tube 3, positioning and supporting its bottom, reducing its shaking during transfer, and protecting the test tube, thereby improving the stability of transfer.

[0034] It can be understood that since the auxiliary frame 23 is mounted on the support rod 22, it can slide up and down along the support rod 22. Therefore, when it is inserted into the graphite heating seat 1, during the downward insertion process, it is flat against the upper surface of the graphite heating seat 1 and pushed flat to fit against the bottom surface of the flat support plate 21, which is easy to operate and use.

[0035] In this embodiment, in order to protect the extension tube portion 33 during the heating process, refer to Figure 1-4A plurality of guardrails 2301 are arranged on the top of the auxiliary frame layer 23, and a plurality of guide holes 2101 are opened on the top of the flat support plate 21, and the guardrails 2301 are slidingly connected with the guide holes 2101 in a one-to-one correspondence. When the transfer bracket 2 is moved downward, the auxiliary frame layer 23 is flat against the upper surface of the graphite heating seat 1, and the flat support plate 21 continues to move downward, then the guardrails 2301 are exposed through the guide holes 2101 to enclose the extension tube portion 33.

[0036] It can be understood that there are four guardrails 2301 , corresponding to the square graphite heating seat 1 ; if the graphite heating seat 1 is circular, two arc-shaped guardrails 2301 can also achieve a protective effect, depending on the specific shape of the graphite heating seat 1 .

[0037] Optionally, the guardrail 2301 is in an inverted U shape, wherein, in order to improve the structural strength of the guardrail 2301, a plurality of reinforcement rods 2302 are provided on the inner side of the guardrail 2301, and the reinforcement rods 2302 are vertically fixed.

[0038] In this embodiment, in order to facilitate taking the transfer bracket 2, heat-insulating handles 2102 are provided on both sides of the flat support plate 21 to prevent burns when taking the transfer bracket 2.

[0039] In this embodiment, in order to facilitate the installation and removal of the foot 222, a groove is formed on the top of the foot 222, and the bottom end of the rod body 221 is threadedly connected to the groove.

[0040] It can be understood that after removing the foot 222, the auxiliary frame layer 23 can be removed downwards, so as to facilitate the assembly of the entire transfer bracket 2 and to facilitate the replacement of a single component when it is damaged.

[0041] In this embodiment, in order to facilitate the lifting operation, the experimental test tube 3 has a lifting function. The graphite heating seat 1 is provided with a lifting mechanism 4, which has a lifting end 401. The lifting mechanism 4 is arranged on the heating seat body 11, and the support seat 12 is arranged on the lifting end 401 of the lifting mechanism 4. It is connected to the heating seat body 11 through the lifting mechanism 4. The lifting mechanism 4 is used to drive the support seat 12 to lift. In the initial state, the lifting mechanism 4 lifts the support seat 12 Raise to the top, at which position, it is convenient to insert the foot 222 into the support seat 12, and the experimental test tube 3 has not been inserted into the test tube slot 101. When heating operation is required, the lifting mechanism 4 is lowered, and the transfer bracket 2 is lowered accordingly. Since the test tube slot 101, the socket 201 and the positioning hole 2303 are all in an aligned state, the experimental test tube 3 can be automatically inserted into the test tube slot 101 during the descending process. Similarly, after the heating is completed, the transfer bracket 2 can be lifted to detach the experimental test tube 3 from the test tube slot 101.

[0042] Specifically, in order to achieve the lifting effect, refer to Figure 5 The lifting mechanism 4 can adopt a combination of a wire lever 41, a lifting frame 42 and a driving motor 43. A cavity is provided on one side of the graphite heating seat 1. Correspondingly, the wire lever 41 is rotatably installed in the cavity and is vertically shaped. A screw hole is opened on the lifting frame 42 and is threadedly connected with the wire lever 41. The cavity has a limiting and guiding function for the lifting frame 42. The output shaft of the driving motor 43 is fixedly connected to the wire lever 41. The wire lever 41 is driven to rotate by the driving motor 43, and then the lifting frame 42 is driven to lift. Among them, the lifting frame 42 is the lifting end of the lifting mechanism 4, which is connected to the support seat 12.

[0043] It can be understood that two lifting mechanisms 4 can be used, which are respectively arranged on both sides of the graphite heating seat 1, and one lifting frame 42 connects the two support seats 12; the lifting mechanism 4 can also be used with only one lifting frame 42, which can be in a square frame shape and is mounted on the outside of the graphite heating seat 1, and the four support seats 12 are all connected to the lifting frame 42; the lifting mechanism 4 can also use hydraulic push rods and other equipment with telescopic functions to achieve the purpose of lifting operation.

[0044] The specific working process of the utility model is as follows: when inserting the test tube, the lifting mechanism 4 lifts the support seat 12 to the highest position, and the auxiliary frame layer 23 slides down to form a double-layer support frame with the flat support plate 21 to support the experimental test tube 3. At this time, the experimental test tube 3 is inserted into the corresponding insertion hole 201 and the positioning hole 2303 in turn; during the heating operation, the lifting mechanism 4 lowers the support seat 12 to the lowest position, and the experimental test tube 3 is automatically inserted into the test tube slot 101 during the descending process, and is heated by the graphite heating seat 1, and the boiling is avoided by extending the tube portion 33. The evaporating solvent splashes out from the experimental test tube 3; after the heating treatment, the lifting mechanism 4 lifts the support seat 12 to the highest point again, and the transfer bracket 2 can be transferred by grasping the heat-insulating handle 2102, and the experimental test tube 3 placed on the flat support plate 21 with the step 32 can be transferred simultaneously, and it can also be used as a test tube holder through the foot 222, and supported and placed on the desktop, which is convenient for subsequent operations; wherein, in the process of inserting the test tube into the test tube slot 101, the auxiliary shelf layer 23 will be automatically pushed to fit the flat support plate 21, and will automatically slide down during the lifting to form an auxiliary support.

[0045] The entire workflow is completed, and the contents not described in detail in this specification belong to the prior art known to professional and technical personnel in this field.

[0046] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto.
