Laboratory bench cabinet with protective structure

Abstract

This utility model relates to the field of laboratory equipment technology, and in particular to a laboratory bench cabinet with a protective structure. The cabinet includes a laboratory bench with a guide rail at its front end, a slider on the upper side of the guide rail, positioning blocks on both sides of the upper end of the slider, and a transparent protective plate installed in the middle of each positioning block. Two sets of transparent protective plates are used. This utility model designs a laboratory bench cabinet with a protective structure, utilizing movable transparent protective plates. Experimenters can operate the equipment by passing their hands through circular holes. The protective plates can move towards each other and connect in the middle of the bench when needed, effectively preventing splashes from spreading to both sides during the experiment. Combined with protective baffles at the edge of the bench, this forms double protection, significantly reducing the risk of liquid or solid particles contaminating the bench or floor, or injuring experimenters, greatly improving the safety of experimental operations.

Description

Technical Field

[0001] This utility model relates to the field of laboratory equipment technology, and in particular to a laboratory cabinet with a protective structure. Background Technology

[0002] In laboratory environments such as scientific research experiments, chemical analysis, and biological detection, the workbench is the core area for various operations. During the experiment, various chemical reagents, biological samples, and operations such as heating and mixing are often involved. These operations inevitably produce splashed liquids, volatile gases, or scattered solid particles.

[0003] Traditional laboratory benches have relatively simple cabinet structures, typically only providing basic work surface and cabinet storage functions, lacking effective protective measures. If liquids are accidentally spilled during operation, they can easily flow to the edge of the work surface, contaminating the floor and potentially corroding the floor or causing people to slip. If corrosive or toxic liquids are not collected in time, the consequences can be even more serious. In addition, waste generated during experiments, such as used test tubes, filter paper, and labels, usually needs to be manually cleaned and disposed of. For experiments that generate frequent waste, this is cumbersome, and trash cans are often located on the ground, making them inconvenient to access, especially when there is limited space under the laboratory bench or when the operating space is tight.

[0004] To address the above issues, it is necessary to design a laboratory cabinet with a protective structure to overcome these problems. Utility Model Content

[0015] Beneficial effects

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] 1. In this utility model, an experimental table cabinet with a protective structure is designed. Using a movable transparent protective plate, the experimenter's hand passes through a round hole to operate. The protective plate can move towards each other and be spliced ​​in the middle of the table when needed, effectively blocking the spread of splashes that may be generated during the experiment to both sides. Combined with the protective baffles on the edge of the table, a double protection is formed, which significantly reduces the risk of liquid or solid particles contaminating the table or floor or injuring the experimenter, and greatly improves the safety of experimental operations.

[0018] 2. In this utility model, an experimental bench cabinet with a protective structure is designed, which integrates a water tank, a flow guide channel, and an arc-shaped protective plate. Liquids that accidentally spill during the experiment will be intercepted by the protective baffle and the protective plate. By manually moving the scraper, the liquid on the bench can be guided to one side of the arc-shaped protective plate, then flows into the flow guide channel and finally collects in the water tank. This allows the liquid to be collected quickly and centrally, avoiding the safety hazards of liquid leakage causing ground pollution, corrosion, or slipping, and facilitating subsequent unified treatment.

[0019] 3. In this utility model, by designing an experimental table cabinet with a protective structure, the experimenter can easily control the extension and retraction of the electric telescopic rod through the controller, which drives the trash can to slide out from under the table along the slide rail for easy placement of trash. The trash can itself is designed with a flip-top lid structure, which does not require manual opening and is more convenient to use. In addition, it adopts an upper and lower layer design, which makes it convenient for the experimenter to perform preliminary classification of dry and wet waste, simplifies the trash cleaning steps in the experimental process, saves the experimenter's time, and improves work efficiency.

[0030] The working process of this utility model is as follows: Using the experimental bench cabinet with a protective structure designed in this scheme, during operation, two sets of transparent protective plates 13 on the upper side of the manually moved guide rail 12 are moved towards each other. The sealing concave strip 16 and sealing convex strip 17 are then joined to position the two sets of transparent protective plates 13 in the middle of the experimental bench cabinet 1. The experimenter performs the experiment by inserting their hand through the circular hole 11. During the experiment, liquid inevitably spills onto the table surface. The protective baffle 5 and guide rail 12 protect against this spillage. The liquid on the table surface is then manually guided by the scraper 10 into the guide groove 6 on one side of the arc-shaped protective plate 7. The liquid then flows into the water tank 3 for collection, facilitating rapid collection and preventing leakage of experimental liquids. To avoid unnecessary trouble, the liquid enters the trash can 31 through an unmarked universal corrugated pipe for storage. The electric telescopic rod 20 and the drive motor 33 are controlled by an external controller to work together. The electric telescopic rod 20 extends and retracts, which drives the moving plate 23 connected to the side of the connecting block 22 to move along the first slide rail 28. At the same time, the moving plate 23 on the side of the auxiliary block 27 is guided by the conveyor belt 25 to slide along the second slide rail 29. This makes it easy to push the trash can 31 out from the bottom of the test bench cabinet 1. The experimenter can push the trash can flip cover 19 to flip it over and discard the trash into the trash can 31, which is convenient for storing experimental waste. The trash can 31 is designed with upper and lower layers to facilitate the classification of dry and wet waste.
