Description

Technical Field

[0001] This utility model relates to the field of tool rack technology, and in particular to a positioning support for tissue culture tools. Background Technology

[0002] In plant tissue culture, scalpels and forceps are indispensable experimental tools that require high-temperature sterilization and cooling before use. Currently, common methods of holding these tools in tissue culture experiments include homemade simple foam supports or centrifuge tube racks, where the handles of the scalpels and forceps are usually inserted for temporary fixation. However, these devices are simple in structure and primarily made of plastic, presenting several problems in practical use. First, while scalpels and forceps require high-temperature sterilization, plastic supports are prone to thermal melting and deformation under high temperatures, causing the tools to fall and resulting in contamination. Re-sterilization is then necessary before continuing operation, indicating poor stability. Furthermore, plastic supports are lightweight, while tissue culture scalpels and forceps have a high center of gravity. To achieve stable support, the size of the support often needs to be increased, wasting tissue culture space and reducing operational efficiency. These problems are prevalent in currently available tissue culture tool supports and have not yet been effectively resolved. Utility Model Content

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] The purpose of this invention is to provide a positioning support for tissue culture tools to solve the problems existing in the prior art. It has a compact structure, saves space, is not prone to thermal melting deformation, has high stability, and is conducive to improving operational efficiency.

[0025] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0026] like Figures 1-4 As shown, this embodiment provides a tissue culture tool positioning bracket, including a metal base 1, a panel 2, a clamping plate 3, and a support plate 4. The panel 2 is located above the base 1 and is fixedly connected to the base 1 through the support plate 4. The panel 2 is provided with a plurality of first positioning holes 5 arranged at intervals. The clamping plate 3 is disposed between the panel 2 and the base 1 and is fixedly connected to the support plate 4. The clamping plate 3 is provided with a plurality of second positioning holes 6 that correspond one-to-one with the first positioning holes 5 and are aligned one-to-one in the vertical direction.

[0027] The positioning bracket is made of metal. Compared with plastic materials, it has good heat resistance and strength, is not prone to hot-melt deformation, and has a density greater than that of plastic materials. It can achieve stable support with a smaller volume, has a compact structure, saves space, and can position and place tissue culture tools through the first positioning holes and the second positioning holes that are vertically aligned one by one, realizing two-layer clamping restraint, effectively preventing the tissue culture tools from sliding, tilting or toppling, improving the stability of placement and the safety of operation, and being conducive to improving operation efficiency.

[0028] Among them, the first positioning hole 5 and the second positioning hole 6 are vertically aligned and overlapped, and the offset error does not exceed 0.03 mm. After the tissue culture tool is inserted into the aligned first positioning hole 5 and second positioning hole 6, the deflection angle does not exceed 1°, achieving high-stability placement and preventing the tissue culture tool from toppling and colliding.

[0029] Two support plates 4 are fixedly connected to both ends of the base 1 respectively. Both ends of the panel 2 are fixedly connected to the two support plates 4 respectively. Both ends of the clamping plate 3 are fixedly connected to the two support plates 4 respectively. The base 1, the panel 2 and the clamping plate 3 are parallel to each other. The base 1, the panel 2, the clamping plate 3 and the support plate 4 are all made of stainless steel, with good strength, corrosion resistance and high-temperature resistance, stable structure, not easily damaged, and can be directly subjected to conventional laboratory sterilization treatments such as ultraviolet irradiation or alcohol wiping to ensure long-term repeated use, meeting the requirements of aseptic laboratory use; during production, the stainless steel plate is processed by cutting and welding, and finally the positioning bracket is obtained, making the positioning bracket have good high-temperature resistance and strength requirements for long-term use. The clamping plate 3 is fixed at the vertical midline position of the two side support plates 4 by welding, and the welding joint between the panel 2 and the support plate 4 is chamfered to avoid dust accumulation at sharp corners and improve safety.

[0030] The overall shape of the positioning bracket is a flat "day" - shaped structure. Its front and rear open structure design does not block the operation line of sight, facilitates the picking, placing, cleaning and ventilation while preventing the instruments from slipping, and is suitable for various experimental environments.

[0031] In this embodiment, there are six first positioning holes 5, three of which are tissue culture knife positioning holes ( Figure 3 the three left first positioning holes 5 in Figure 3The three first positioning holes 5 on the right side are arranged sequentially, as are the three positioning holes for tissue culture knives and the three positioning holes for forceps. During use, the tissue culture tools are positioned by inserting the handles into the first positioning holes 5 and the second positioning holes 6, ensuring that the sterile areas of the blades and forceps that directly contact the experimental materials are suspended upwards. This avoids cross-contamination caused by contact between tools and reduces the risk of contact with the work surface and bacterial contamination, effectively minimizing secondary contamination caused by improper placement during tissue culture operations. The small contact area between the tissue culture tool handle and the positioning bracket further reduces potential contamination points and improves overall hygiene control. In plant tissue culture experiments, scalpels and forceps require high-temperature sterilization before and after use. After sterilization, they need to cool naturally, often requiring multiple instruments to be placed simultaneously. This positioning bracket allows for the placement of multiple scalpels and forceps in designated areas.

[0032] When researchers insert tools such as tissue culture scalpels into the holes on the upper panel, the tool handles penetrate vertically through the corresponding holes in the middle panel. Because the upper and lower holes precisely align, the tools are clamped and constrained by both layers, maintaining a vertical position and effectively preventing shaking and collisions. During tool retrieval, researchers can directly pull out the required tool vertically. The simultaneous release of the upper and lower holes reduces frictional resistance during retrieval.

[0033] In this embodiment, the first positioning holes 5 are arranged sequentially at equal intervals. The distance between two adjacent first positioning holes 5 is not less than 25mm, and this embodiment sets it to 25mm to ensure convenient tool handling and avoid collisions between tools. The 25mm hole spacing design not only conforms to the human operating distance but also avoids the problem of tools snagging each other, which is common in dense designs, thus improving the smoothness of use and experimental efficiency.

[0034] In this embodiment, every two corresponding second positioning holes 6 and first positioning holes 5 have the same shape and size, which can achieve stable positioning of the tool.

[0035] In this embodiment, the bottom of the base 1 is fixed with an anti-slip rubber pad 7 to enhance the friction with the experimental table surface, which is suitable for operating table surfaces of different materials.

[0036] The structural advantages of this utility model are mainly reflected in the following aspects:

[0037] (1) Double-layer perforated plate vertical positioning structure: The double-layer positioning design of the panel and clamping plate allows the scalpel and forceps to be vertically positioned by passing through the upper and lower perforations from the handle, which can effectively ensure their stable upright position and prevent slippage or tilting. The vertical deflection angle of the tool is controlled within 1°, which has better stability than the traditional single-layer support (the tool tilt angle is more than 15°).

[0038] (2) Reduce the risk of contamination: The handle is fixed so that the sterile parts such as the blade and forceps are suspended above the support, avoiding contact with the support body and other tools, reducing the possibility of bacterial contamination from above, and reducing the risk of secondary contamination.

[0039] (3) Compact and small, suitable for confined spaces: The positioning bracket base occupies only 51.48cm². 2 (19.8cm long, 2.6cm wide, and approximately 3cm high) It is suitable for experimental sites with limited space, such as tissue culture chambers and clean benches.

[0040] (4) The material is sterilizable and easy to clean: It is made of stainless steel, which has good high temperature resistance, corrosion resistance and structural strength. It can be disinfected directly by ultraviolet light, alcohol wiping or high temperature sterilization. It is stable and reliable for long-term use. The open structure of the bracket is also easy to clean and visualize management.

[0041] This invention effectively solves the problems of heat melting, contamination, space waste and safety hazards in the temporary placement of existing tissue culture experimental tools. It has the advantages of compact structure, precise positioning, simple operation and durable materials, and is suitable for the standardized storage needs of scalpels and forceps in various plant tissue culture laboratories.

At the same time, for those skilled in the art, there will be changes in the specific implementation methods and application scope based on the idea of ​​this utility model. In summary, the content of this specification should not be construed as a limitation of this utility model.
