In the description of the present invention, it is also necessary to explain that, unless otherwise clearly specified and limited, the terms "set", "install", "connect", and "connect" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances. Example

[0022] like Figure 1-Figure 3As shown, the laboratory vessel positioning device provided in this embodiment includes a bottom plate 1 with a plurality of measuring cup positioning grooves 12 and reagent bottle positioning grooves 11 spaced apart at the upper end, a bottom bracket 2 is sleeved on each reagent bottle positioning groove 11, and a laboratory vessel protection sleeve 3 is provided on each bottom bracket 2, wherein the laboratory vessel protection sleeve 3 is composed of a protection sleeve 31 and a lower support plate 33 fixedly connected to the lower end of the protection sleeve 31, wherein the lower support plate 33 is detachably connected to the bottom bracket 2, and the middle part of the protection sleeve 31 has a laboratory vessel sleeve space. In this way, when in use, the bottom bracket 2 is first clamped and fixed on the reagent bottle positioning groove 11 or the measuring cup positioning groove 12, and then the measuring cup or reagent bottle is sleeved in the protective sleeve 31 of the laboratory vessel protection sleeve 3, and the lower support plate 33 at the lower end of the laboratory vessel protection sleeve 3 is connected and matched with the bottom bracket 2, so that the reagent bottle and the measuring cup can be fixed on the bottom plate 1. After the labware protective cover 3 is set on the measuring cup and the reagent bottle, it can play a protective role. Even if it is hit during the experiment, after it falls over, the reagent bottle and the measuring cup are not easily damaged. In the specific implementation, the measuring cup can be directly placed in the measuring cup positioning groove 12. When placed in this way, in order to form the protection of the measuring cup, the measuring cup positioning groove 12 can be placed between the two reagent bottle positioning grooves 11. Of course, the labware protective cover 3 can also be directly matched with the measuring cup positioning groove 12 to position and protect the measuring cup.

[0023] Furthermore, the protective sleeve 31 is made of a flexible transparent plastic, and at least four rectangular label slots 32 are provided on the outer side of the protective sleeve 31. The provision of multiple label slots 32 can facilitate the experimenter to fill in different labels according to different solvents, so as to quickly find the desired solvent. Compared with the existing labeling method, this method is faster and more convenient to replace labels.

[0024] Further, the bottom bracket 2 is composed of a lower socket 21 and an upper connecting portion 22 (the lower socket 21 and the upper connecting portion 22 are integrally formed); the reagent bottle positioning groove 11 is fan-shaped, the lower socket 21 is inserted into the reagent bottle positioning groove 11, the upper connecting portion 22 extends out of the reagent bottle positioning groove 11, and the lower end surface is in close contact with the upper end surface of the bottom bracket 2. The measuring cup positioning groove 12 is circular, and the lower socket 21 corresponding to the top support at the measuring cup positioning groove 12 is also circular. In this way, after the lower socket 21 is inserted into the reagent bottle positioning groove 11, a fan-shaped limit block is formed in the circumference formed by the reagent bottle positioning groove 11. Therefore, after the bottom bracket 2 is sleeved on the reagent bottle positioning groove 11, it cannot rotate, and the bottom bracket 2 can be limited. The upper connecting portion 22 extends out of the reagent bottle positioning groove 11, and a step is formed between the lower socket 21, and the connection between the bottom plate 1 is stable, and it is also convenient to pull out and replace.

[0025] Further, the upper connecting portion 22 is circular, and a circle of positioning holes 23 is provided on the upper connecting portion 22, and the positioning holes 23 are circumferentially distributed with the center of the upper connecting portion 22 as the center of the circle; a plurality of plug-in blocks 34 corresponding to the positioning holes 23 are provided on the lower supporting plate 33 of the experimental vessel protection cover 3, and the experimental vessel protection cover 3 is fixed on the bottom bracket 2 after the plug-in blocks 34 cooperate with the positioning holes 23. The plug-in blocks 34 in this embodiment are arc-shaped, and can be rectangular in specific implementations, and the plug-in blocks 34 are hard plug-in blocks 34. In this way, the upper connecting portion 22 can be circular and can be well sleeved with the experimental vessel protection cover 3. After the positioning holes 23 are provided on the upper connecting portion 22 and the plug-in blocks 34 are provided at the lower end of the lower supporting plate 33, when the plug-in blocks 34 are inserted into the positioning holes 23, the experimental vessel protection cover 3 can be fixed on the support plate. This socket-and-socket positioning method is convenient for installation and disassembly, and has a stable structure.

[0026] If the reagent bottle has a handle, a handle notch for the handle to extend out is also provided on the protective sleeve 31 and beside the label slot 32. In this way, the handle notch can facilitate the handle to extend out. Example

[0027] like Figure 4 As shown, the difference between the experimental vessel positioning device provided in this embodiment and the embodiment 1 is only that the connection structure between the base 2 and the experimental vessel protection cover 3 is different. Specifically, in this embodiment, the upper connection part 22 of the base 2 is circular, a first magnet 24 is embedded in the upper connection part 22, and a second magnet 35 corresponding to the first magnet 24 and magnetically matched is provided on the lower support plate 33. In this way, the first magnet 24 and the second magnet 35 can generate magnetic force and be fixed on the base 2 after the experimental vessel protection cover 3 approaches and aligns with the upper connection part 22. Example

[0028] like Figure 5 As shown, the experimental vessel positioning device provided in this embodiment is different from that in Embodiment 1 only in the connection structure between the base 2 and the experimental vessel protective cover 3. Specifically, the outer edge of the upper connecting portion 22 of the base 2 in this embodiment is bent upward to form a positioning cover that matches the lower support plate 33.

[0029] In the specific implementation, for a reagent bottle or other product with a narrowed diameter at the upper end, a narrowing sleeve 4 with a notch can be connected to the protective sleeve 31 of Examples 1 to 3, and the narrowing sleeve 4 is composed of an arc-shaped belt with a notch and a plurality of plastic strips connected between the arc-shaped belt and the protective sleeve (such as Figure 6 as shown).

[0030] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit the technical solution. Ordinary technicians in this field should understand that those modifications or equivalent replacements of the technical solution of the utility model without departing from the purpose and scope of the technical solution should be included in the scope of the claims of the utility model.
