Abstract
Description
Technical Field
[0001] This utility model relates to the field of teaching equipment technology, specifically a student experimental desk. Background Technology
[0002] In students' science experiments, suitable experimental desks are a crucial foundation for ensuring the smooth conduct of experimental teaching. Traditional student desks have limited functions, only meeting basic needs for writing and placing books, and cannot meet the special requirements of experimental operations. In chemistry, biology, and other experiments, traditional desks lack dedicated experimental areas, making it easy for liquids to spill, contaminating the desktop and even damaging the desk. Furthermore, the lack of dedicated space for experimental instruments and reagents leads to disorganized placement, affecting experimental efficiency and posing safety hazards.
[0003] Some schools use ordinary laboratory workbenches as desks for student experiments. However, these workbenches are large, inflexible, and cannot be adjusted according to teaching needs. They are also expensive and not suitable for large-scale deployment in ordinary classrooms. In addition, most existing experimental desks do not take into account the combination of student writing and experimental operation. Students need to write frequently in the experimental area during the experiment, which is inconvenient and affects the learning experience. Therefore, a student experimental desk is proposed.

When writing is required, the writing desk 9 can be unfolded to provide a dedicated writing area; when conducting experiments, the writing desk 9 can be folded to save space and facilitate experimental operations. A placement trough 10 is placed on one side of the top of the workbench 6 to hold experimental containers such as beakers and test tubes, preventing them from tipping over. A water weir 11 is welded to the top of the workbench 6, located on one side of the placement trough 10. Its moderate height prevents spilled liquid from spreading outwards during experiments, avoiding contamination of the entire workbench. A water outlet 12 penetrates the inner top surface of the water weir 11 to drain the liquid collected within it.
[0025] In this embodiment, a transmission pipe 13 is snapped onto the top of the water inlet 12, and the end of the transmission pipe 13 away from the water inlet 12 is fixed to the bottom of the top fixing groove 14.
[0026] Specifically, the transfer pipe 13 is snapped onto the top of the water inlet 12, and its other end is fixed to the bottom of the top fixing groove 14. The transfer pipe 13 is made of corrosion-resistant plastic or rubber tubing, which can transfer the liquid discharged from the water inlet 12 to the top fixing groove 14. The top fixing groove 14 can be used to place waste liquid collection containers for centralized collection and treatment of experimental waste liquid, which meets environmental protection requirements.
[0027] In this embodiment, a fixing frame 15 is snapped into the bottom end of the top fixing groove 14, and a through rod 16 is fixedly connected to the top end of the fixing frame 15 on one side of the top fixing groove 14.
[0028] Specifically, the fixing bracket 15 is snapped into the bottom end of the top fixing groove 14 to fix the through rod 16.
[0029] In this embodiment, a rotating shaft 17 is sleeved on the outer wall of the through rod 16, and a connecting frame 18 is rotatably connected to one side of the outer wall of the rotating shaft 17. A frame rod 19 is snapped into the inner wall of the connecting frame 18.
[0030] Specifically, the through rod 16 is fixedly connected to the top of the fixed frame 15 on one side of the top fixing groove 14, and the rotating shaft 17 sleeved on its outer wall can rotate flexibly.
[0031] In this embodiment, a connecting arm 20 is rotatably connected to one end of the support rod 19, and a rotating joint 21 is rotatably connected to the end of the connecting arm 20 away from the support rod 19.
[0032] Specifically, through the cooperation of the rotating shaft 17, connecting frame 18, support rod 19, connecting arm 20 and rotating joint 21, multi-directional and multi-angle rotation and adjustment can be achieved, which facilitates the fixing of experimental instruments of different types and sizes.
[0033] In this embodiment, a threaded fixing seat 23 is fitted on the inner wall of the rotating joint 21, and a clamp 24 is rotatably connected to the inner wall of the threaded fixing seat 23.
[0034] Specifically, by rotating clamp 24, the tightness of clamp 24 can be adjusted, thereby firmly fixing experimental instruments, such as test tubes, beakers, and burettes, to ensure the safety and accuracy of experimental operations.
[0035] In this embodiment, a spring rod 22 is rotatably connected to one side of the outer wall of the rotating joint 21, and the end of the spring rod 22 away from the rotating joint 21 is rotatably connected to one side of the outer wall of the frame rod 19.
[0036] Specifically, the spring rod 22 is rotatably connected to one side of the outer wall of the rotating joint 21, and the other end is rotatably connected to one side of the outer wall of the support rod 19. The spring rod 22 is elastic and can provide a certain supporting force and buffering force for the rotating joint 21, making the experimental instrument more stable after it is fixed. The threaded fixing seat 23 is locked in the inner wall of the rotating joint 21, and the clamp 24 is rotatably connected to the inner wall of the threaded fixing seat 23.
[0037] The working principle and usage procedure of this utility model are as follows: Before conducting the experiment, students place the required experimental instruments and reagents in the placement slot 10 of the workbench 6. According to the experimental needs, the writing desk 9 is folded down via the rotating shaft 7 and connecting shaft 8 to create sufficient experimental space. The monitor 4 and main unit 5 are turned on to review the experimental instructions, understand the experimental steps and precautions, and adjust the instrument fixing mechanism according to the type and size of the experimental instruments. By rotating the rotating shaft 17, connecting frame 18, support rod 19, connecting arm 20, and rotating joint 21, the clamp 24 is adjusted to a suitable position and angle. The clamp 24 is then rotated to place the experimental instrument... The instrument is securely fixed to the clamp 24, and the spring rod 22 provides support and cushioning to ensure the stability of the instrument. During the experiment, students perform experimental operations on the workbench 6. The water weir 11 can block the liquid that is spilled during the experiment to prevent the liquid from contaminating the workbench. If any liquid is spilled, it will flow into the water weir 11 and be transferred to the top fixed tank 14 through the water guide 12 and the transmission pipe 13 to achieve centralized treatment of waste liquid. When it is necessary to record experimental data or write, the writing desk 9 is unfolded by rotating the shaft 7 and connecting the shaft 8, and writing is done on the writing desk 9. At the same time, relevant information can be viewed on the display 4 at any time to assist in the experimental operation.
