Description

Technical Field

[0001] This utility model relates to the field of laboratory testing technology, and in particular to a test tube uprighting device. Background Technology

[0002] The main functions of a laboratory test tube cold bath include controlling reaction rates, preventing explosions, reducing side reactions, maintaining reagent stability, and ensuring selective reactions. By providing a low-temperature environment, the cold bath effectively lowers the temperature of the reaction system, thereby slowing down the rate of chemical reactions and preventing side reactions or explosion risks caused by temperature increases.

[0003] Currently, in existing laboratory test tube cold baths, test tube racks are used to fix the tubes in place to prevent accidental slippage. However, this cannot guarantee that the test tubes will always remain upright, and the samples inside the test tubes are easily affected by the external environment, which can affect the laboratory testing results. Utility Model Content

[0004] The purpose of this invention is to solve the problem that existing laboratory test tube cold baths use test tube racks to prevent samples from slipping due to accidental contact, but this cannot guarantee that the test tubes will always remain upright, and the samples inside the test tubes are easily affected by the external environment, which affects the laboratory testing results. Therefore, this invention proposes a test tube uprighting device.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A test tube uprighting device includes a sleeve, a test tube body, and a water bath. The test tube body is inserted into the sleeve. A first washer is engaged at the bottom between the inner circumferences of the sleeve, and a second washer is engaged at the top between the inner circumferences of the sleeve. The first and second washers are engaged with the test tube body. A disc pad is provided on the bottom inner wall of the sleeve. The bottom end of the test tube body is placed on the disc pad, and a first cork is engaged at the top end of the test tube body.

[0007] Furthermore, a first thermometer is inserted into the first cork and inserted into the test tube body.

[0008] Furthermore, the sleeve is inserted into the water bath.

[0009] Furthermore, a second cork is attached to the top of the water bath, and a second thermometer is inserted into the second cork.

[0010] Furthermore, both the first washer and the second washer have annular structures.

[0011] The beneficial effects of this utility model are as follows:

[0012] The test tube body is inserted into the first and second washers, thus keeping the test tube body upright at all times. This prevents the sample from tipping over due to accidental contact and also avoids contact between the outer circumference of the test tube body and the sleeve. Then, a disc is placed at the bottom of the test tube body, thus preventing contact between the bottom of the test tube body and the bottom of the sleeve, thereby preventing the sample inside the test tube body from being affected by the external environment.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0018] Reference Figures 1-3 A test tube upright device includes a sleeve 1, a test tube body 5 and a water bath 8. The upper cover of the water bath 8 has a hole for engaging the sleeve 1. The sleeve 1 is inserted into the water bath 8 so that the sleeve 1 is in a vertical state.

[0019] The test tube body 5 is inserted into the sleeve 1. The bottom of the inner circumference of the sleeve 1 is engaged with a first washer 2, and the top of the inner circumference of the sleeve 1 is engaged with a second washer 3. Both the first washer 2 and the second washer 3 are annular structures. The first washer 2 and the second washer 3 are engaged with the test tube body 5, so that the test tube body 5 always remains upright. The test tube body 5 is inserted into the first washer 2 and the second washer 3, thereby avoiding contact between the outer circumference of the test tube body 5 and the sleeve 1.

[0020] The bottom inner wall of the sleeve 1 is provided with a disc pad 4, and the bottom of the test tube body 5 is placed on the disc pad 4. The disc pad 4 is placed on the bottom of the test tube body 5, thereby avoiding contact between the bottom of the test tube body 5 and the bottom of the sleeve 1, and thus preventing the sample in the test tube body 5 from being affected by the external environment.

[0021] The top of the test tube body 5 is fitted with a first cork 6, and a first thermometer 7 is inserted into the first cork 6. The first thermometer 7 is inserted into the test tube body 5 and measures the temperature inside the test tube body 5.

[0022] A second cork 9 is attached to the top of the water bath 8, and a second thermometer 10 is inserted into the second cork 9 to detect the temperature inside the water bath 8, so that the temperature inside the water bath 8 can be adjusted in time by adding cold water when the water temperature is higher than the warning line.

[0023] The working principle of this embodiment is as follows: In use, the test tube body 5 is inserted into the sleeve 1, and the test tube body 5 is inserted into the first washer 2 and the second washer 3 to avoid contact between the outer circumference of the test tube body 5 and the sleeve 1, so that the test tube body 5 always remains upright. Then, the disc pad 4 is placed at the bottom of the test tube body 5 to avoid contact between the bottom of the test tube body 5 and the bottom of the sleeve 1, thereby preventing the sample in the test tube body 5 from being affected by the external environment. Next, the first cork 6 is inserted at the top of the test tube body 5 to keep the test tube body 5 warm, and the temperature inside the test tube body 5 is detected by the first thermometer 7.

[0024] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
