Technical Field

[0001] The utility model relates to a multifunctional experimental stool for a clean space, in particular to a multifunctional experimental stool suitable for use in a sterile laboratory, belonging to the technical field of laboratory utensils. Background Art

[0002] A sterile laboratory, also known as a clean laboratory or a biosafety laboratory, is mainly used for research in microbiology, biomedicine, biochemistry, animal experiments, gene recombination, and biological products. When in use, it is necessary to ensure personal safety, environmental safety, waste safety, and sample safety. Therefore, certain technical indicators of the laboratory itself are required to meet these requirements. Among them, the requirement for the cleanliness level is particularly important for the safety and effectiveness of the experiment.

[0003] An experimental stool is an item often used in a laboratory. In the prior art, for example, Chinese patents CN216124127U, CN 210446279U, CN217185386U, CN219249657U, etc. have made a series of improvements in terms of the comfort of using the experimental stool, the convenience of adjustment, the stability of the structure, the mobility, and the durability. Although these experimental stools can also be used in a sterile laboratory, due to the large number of structural components, once they come into contact with experimental supplies, bacteria are likely to grow in the dead corners of the structure and are not easy to be thoroughly cleaned and sterilized, which easily causes the cleanliness level of the sterile laboratory to fail to meet the standard. Moreover, during the biological experiment process, these experimental stools can only provide the function of resting for the experimental personnel, and the functions are relatively single.

[0004] Therefore, it is very necessary to provide a multifunctional experimental stool suitable for use in a sterile laboratory, which has a simple structure, is not easy to breed bacteria, is easy to clean and sterilize, and has an auxiliary function for biological experiments. Summary of the Utility Model

[0005] The purpose of the utility model is to provide a multifunctional experimental stool for a clean space, which is composed of a stool leg with a support structure and a detachable stool surface. It has a simple structure, can be used for rest, and can also be used as an experimental auxiliary tool. It can be used as a support during the cleaning, draining, or leakage liquid receiving of experimental bottles, which can reduce leakage liquid pollution and is easy to achieve comprehensive disinfection and sterilization. Therefore, it is particularly suitable for use in a sterile laboratory.

[0006] The utility model is realized through the following technical solutions: A multifunctional experimental stool for a clean space includes a stool surface and stool legs. The stool legs have a support structure and are composed of at least three support rods and fixing rings respectively connecting the ends of the three support rods. The back side of the stool surface is a groove recessed inward, and a buckle is provided at the bottom of the groove. The stool surface is detachably installed on the fixing ring through the buckle.

[0007] The stool surface has a disc structure, and the diameter of the stool surface is larger than the diameter of the fixing ring.

[0008] Below the corresponding fixed ring, there is also an installation ring. The outer side of the installation ring is fixed on three support rods, and a support edge for placing the stool surface is extended inward from the inner side of the installation ring towards the center of the circle.

[0009] Both the installation ring and the fixed ring are horizontally arranged.

[0010] The installation ring is located in the middle of the three support rods.

[0021] The present utility model will be further described in detail below in conjunction with the embodiments, but the embodiments of the present utility model are not limited thereto.

[0022] Embodiment:

[0023] The experimental stools currently used in sterile laboratories usually only have the function of a stool. In the prior art, in order to improve the convenience and comfort of using the experimental stools, functional structures are often added additionally, making the structure of the experimental stools complex. However, since these experimental stools are prone to breeding bacteria and are not easy to clean, they are not suitable for use in sterile laboratories. Therefore, to solve the problem of the single function of the experimental stools in the existing sterile laboratories, this embodiment provides an experimental stool with a simple structure, easy to clean and sterilize without dead corners, and diverse functions.

[0024] See Figure 1 As shown, the experimental stool mainly consists of a stool surface 1 and stool legs. Among them, the stool legs are a bracket structure composed of three support rods 2, a fixing ring 3, and an installation ring 6. The structural composition is simple. The ends of the three support rods 2 are respectively connected to the fixing ring 3. The support rods 2 are used as the supporting components of the entire bracket structure, and the three support rods 2 can be equally spaced. The installation ring 6 is located below the fixing ring 3. As Figure 1 shown, the installation ring 6 can be arranged in the middle of the three support rods 2, and both the installation ring 6 and the fixing ring 3 are horizontally arranged. The stool surface 1 is a disc structure installed on the fixing ring 3 and is a detachable structure. In this embodiment, the diameter of the stool surface 1 is larger than the diameter of the fixing ring 3. The back side of the stool surface 1 can be set as a groove 4 that is recessed inward. A buckle 5 is provided at the bottom of the groove 4, and the stool surface 1 can be detachably installed on the fixing ring 3 through the buckle 5. At the same time, a support edge 7 for placing the stool surface 1 is also provided on the inner side of the installation ring 6 extending towards the center of the circle, and the removed stool surface 1 can be placed on the installation ring 6.

[0025] See Figure 2 As shown, the experimental stool of this embodiment can be used as a water-draining support frame. When in use, the stool surface 1 is removed from the fixing ring 3, and the stool legs are used alone as the support frame. The inner diameter of the fixing ring 3 is 1 - 3 cm, which is suitable for upright bottles, PP barrels, or other small-diameter barrel-shaped containers with a volume of 30 L or more to be inverted for water-draining and drying after cleaning to avoid secondary pollution. For example, the mouth of the upright bottle can be inverted and inserted into the fixing ring 3 for water-draining and drying. When draining water, in order to avoid polluting the laboratory floor, a water-receiving container can be set below the bottle mouth, or the removed stool surface 1 can be placed on the installation ring 6 as Figure 2 shown, with the back side of the stool surface 1 facing upwards, and the water dripping from the bottle is collected by the groove 4 on its back side.

[0026] In the prior art, when cleaning upright bottles or PP buckets, a water pipe is usually inserted into the upright bottle / PP bucket for rinsing. After rinsing, the water in the bottle / bucket is poured out and discarded, which will cause a lot of wastewater to remain in the bucket. It is laborious to pour and not easy to pour clean. At the same time, the washed bucket is left open to dry for a long time, which will cause suspended particles or dust to fall into the bucket, resulting in secondary pollution. The experimental stool of this embodiment provides a supporting function through the stool legs and uses the stool surface 1 to receive water, which can well solve the possible secondary pollution when cleaning upright bottles or PP buckets in a sterile laboratory. The structure is simple and there is no need to add other auxiliary devices.

[0027] See Figure 2 As shown, the experimental stool of this embodiment can also be used as a support frame for a liquid receiving container. When in use, the stool surface 1 is removed from the fixing ring 3, and the stool legs are used alone as a support frame. The length of the support rod 2 can be designed to be 40-60 cm. The stool legs can be moved under the laboratory faucet (the faucet refers to the faucet used to discharge the solution during pipetting operations. For example, when the solution prepared in the clean area of the workshop, the fermentation broth, and the protein solution need to be transported through pipes across rooms or regions to another room or area, the solution is discharged through the faucet. Because in the clean area, to avoid contamination, the liquid receiving container cannot be directly placed on the ground to receive the liquid, so it needs to be placed on a device to avoid contact with the ground). A measuring cup or other liquid receiving container is placed on the fixing ring 3 and aligned with the faucet to receive the solution discharged from the faucet. Since the inner side of the mounting ring 6 extends towards the center of the circle and is provided with a support edge 7 for placing the stool surface 1, the stool surface 1 can be placed on the mounting ring 6 with the groove body 4 on the back side of the stool surface 1 facing upwards. In this way, after the liquid receiving is completed and the liquid receiving container is removed, when the faucet is closed, the remaining dripping liquid can be caught by the stool surface 1, avoiding falling on the ground and causing environmental pollution.

[0028] In the prior art, the valve used for the laboratory faucet is a manual regulating valve, and there will be a dripping phenomenon for 5-10 seconds after it is closed. This is caused by the residual liquid in the faucet. There is no special device for placing the liquid receiving container in the existing laboratory. Usually, a stool with an appropriate height is used, but the stool is wider and larger, taking up space. The residual dripping liquid splashes everywhere when it falls on the stool surface 1. It is more troublesome to wipe it with an alcohol cloth once after each use, otherwise it will contaminate the bottom of the liquid receiving container for the next time. The experimental stool of this embodiment just solves the functions of placing the liquid receiving container and receiving the residual dripping liquid at the same time, and is convenient to use. Of course, for the convenience of using and cleaning the experimental stool, the stool surface 1, the support rod 2, the fixing ring 3 and the mounting ring 6 that make up the experimental stool can all be made of stainless steel materials.

[0029] The above description is only a preferred embodiment of the present invention and does not impose any form of limitation on the present invention. Any simple modification or equivalent change made to the above embodiments based on the technical essence of the present invention falls within the protection scope of the present invention.
