[0002] The chemistry experiment table is an important equipment. Chemical experiment equipment is placed on the table for experiments. In the current high school chemistry experiment courses, there are some violent chemical reactions, which are dangerous and may even cause explosive or impactful chemical reactions. Most chemistry experiment tables are relatively simple and have poor safety. Without any protective measures, it will cause harm to the human body. In addition, some experiments release a large amount of gas during the reaction, which can easily spread into the air, pollute the environment, and affect the health of students and teachers.

[0003] In addition, during the chemical experiments, many experiments will cause the solution to overflow. The overflowed solution will splash onto the laboratory table, which is not convenient for cleaning, and some corrosive solutions will cause certain damage to the skin.

[0004] Therefore, we make improvements to this and propose an organic chemistry experimental device and implementation method. Summary of the invention

[0005] The technical problem to be solved by the present invention is that the chemical experiment table has poor safety, and the solution overflowed during the chemical experiment is corrosive and easily causes injury to the staff.

[0007] As a further solution of the present invention, the protective plate includes a side panel, a slider is fixedly installed on the inner side surface of the side panel, a first electric push rod is fixedly connected to the bottom of the side panel, the first electric push rod is fixedly connected to the bottom surface of the exhaust hood, a rigid bar is fixedly connected to the bottom of the side panel, the bottom end of the rigid bar is connected to the control component, a roller is installed at the bottom end of the table top, and the rigid bar is wrapped around the roller.

[0008] As a further solution of the present invention, the control component includes a pedal, which is slidably mounted on a first slide groove, the outer end of the pedal is hinged with a sliding frame, the bottom end of the pedal is connected to a spring, and the bottom end of the spring is fixedly connected to the laboratory table.

[0009] As a further solution of the present invention, the partition includes a mounting plate, connecting frames are installed on both sides of the mounting plate, a ball joint is movably installed in the middle of the connecting frame, a second electric push rod is movably connected to the middle of the connecting frame, and the second electric push rod is fixedly connected to the filter plate.

[0010] As a further solution of the present invention, an adjustment groove is opened in the middle of the mounting plate, a support frame is slidably installed in the adjustment groove, and a fastening bolt is connected to the back of the support frame.

[0011] As a further solution of the present invention, there are four partitions, and the length and width of the partitions are both half of the length and width of the filter plate.

[0012] As a further solution of the present invention, the connecting frame includes a first connecting shaft and a second connecting shaft that are vertically connected, a connecting ball pin is fixedly connected in the middle of the first connecting shaft and the second connecting shaft, and a mounting groove is opened in the middle position of the first connecting shaft and the second connecting shaft, the second electric push rod is connected to the mounting groove, and the ends of the first connecting shaft and the second connecting shaft extend beyond the mounting plate, and the extending parts are stuck in the slot.

[0013] As a further solution of the present invention, the height of the protective plate is greater than the spacing height between the table top and the exhaust hood.

[0014] An organic chemistry experiment implementation method, using the above-mentioned organic chemistry experiment device, comprises the following steps: S1. Before the experiment, the protective plate naturally falls between the table and the exhaust hood, and the operation window and operation space left between the table and the exhaust hood are sealed. At this time, the spring pushes the pedal upward. When a chemical experiment is required, the control component is stepped on, and the control component and the protective plate are swapped up and down, so that the protective plate is lifted up and the operation window between the table and the exhaust hood is opened; S2. The operator will continue to stand on the control component, set up the partition and experimental equipment above the table, turn the partition 90 degrees along the ball joint or the X-axis or Y-axis direction, support the erected mounting plate through the second electric push rod, and set up support frames at different positions on the mounting plate according to the experimental content, fix the experimental equipment on the support frame, so that the experimental equipment forms an experimental scale; S3.

At this time, the protective plate falls down quickly to separate the operator from the operating table, which can prevent the user from being injured. At the same time, the solution and equipment fragments produced by the explosion fall directly from the through hole of the card slot into the cavity at the bottom of the table board, preventing the chemicals in the chemical experiment from destroying the experimental table during violent reactions.

The connecting frame is rotatably installed on the ball joint and can be flexibly flipped along the X-axis and Y-axis directions to adjust the use angle of the mounting plate. The mounting plate is supported and fixed by the connecting frame, which is convenient for setting up the experimental equipment.

[0017] 3. A cavity is provided in the middle of the table top and is separated by a filter plate to provide an operating platform, so that overflowed solutions or spilled reagents generated during the experiment can be promptly discharged downward from the filter plate to avoid accidental injuries to experimenters caused by residual solutions on the table top.

DETAILED DESCRIPTION

[0021] The specific implementation of the present invention is further described in detail below in conjunction with the accompanying drawings and examples of the specification. The following examples are only used to illustrate the present invention, but cannot be used to limit the scope of the present invention.

[0023] The protective plate 2 includes a side plate 21, a slider 22 is fixedly installed on the inner side surface of the side plate 21, a first electric push rod 23 is fixedly connected to the bottom of the side plate 21, and the first electric push rod 23 is fixedly connected to the bottom surface of the exhaust hood 12. A rigid bar 24 is fixedly connected to the bottom of the side plate 21, and the bottom end of the rigid bar 24 is connected to the control component 3. A roller 25 is installed at the bottom end of the table top 11, and the rigid bar 24 is wound around the roller 25. The side plate 21 is slidably connected to the exhaust hood 12 through the slider 22. The bottom end of the slider 22 is assisted by the first electric push rod 23, which is convenient for buffering when the side plate 21 rises or falls to the end point, so as to avoid the collision between the side plate 21 and the experimental table 1 to damage the instruments inside the device, and the linkage between the side plate 21 and the control component 3 enables the switch of the protective plate 2 to be controlled by the control component 3, thereby improving the protection of the device.

[0024] The control component 3 includes a pedal 31, which is slidably mounted on the first slide groove 13. The outer end of the pedal 31 is hinged with a sliding frame 32. The bottom end of the pedal 31 is connected to a spring 33, and the bottom end of the spring 33 is fixedly connected to the experimental table 1. The pedal 31 slides along the first slide groove 13. When there is no external force test pressure on the pedal 31 and the sliding frame 32, the spring 33 pushes the pedal 31 upward, and the rigid bar 24 connected to the bottom of the pedal 31 pulls the side panel 21 downward to close the side panel 21 downward on the side of the table board 11 to protect the experimental table 1. When there is an external force on the pedal 31 and the sliding frame 32, such as the weight of the experimenter, the pedal 31 squeezes the rigid bar 24 downward, and the rigid bar 24 pushes the side panel 21 upward to open the operating space of the experimental table 1.

[0026] An adjustment slot 42 is provided in the middle of the mounting plate 41 , in which a support frame 43 is slidably installed. A fastening bolt 44 is connected to the back of the support frame 43 . The support frame 43 and the fastening bolt 44 slide along the adjustment slot 42 to determine the position and height, and are fixed by the tightness of the fastening bolt 44 .

[0027] There are four partitions 4, and the length and width of the partitions 4 are half of the length and width of the filter plate 15. The four partitions 4 completely fill the top of the filter plate 15 to partition the experimental space on the filter plate 15, which is convenient for setting up multiple groups of experiments at the same time and for placing experimental equipment.

[0028] The connecting frame 46 includes a first connecting shaft 461 and a second connecting shaft 462 which are vertically connected. A connecting ball pin 463 is fixedly connected in the middle of the first connecting shaft 461 and the second connecting shaft 462. A mounting groove 464 is opened in the middle position of the first connecting shaft 461 and the second connecting shaft 462. The second electric push rod 47 is connected to the mounting groove 464. The ends of the first connecting shaft 461 and the second connecting shaft 462 extend beyond the mounting plate 41, and the extending parts are stuck in the slot 16. The slot 16 and the connecting frame 46 are limited to facilitate the swing of the connecting frame 46 when it is flipped forward and backward or left and right, so as to facilitate the installation of the connecting frame 46.

[0029] The height of the protective plate 2 is greater than the spacing height between the table top 11 and the exhaust hood 12. When the protective plate 2 is completely dropped, it can completely block the space between the table top 11 and the exhaust hood 12 to prevent accidental experimental debris or reagent splashing and injuring people during experiments on the laboratory bench 1.

[0030] An organic chemistry experiment implementation method, using the above-mentioned organic chemistry experiment device, comprises the following steps: S1. Before the experiment, the protective plate 2 naturally falls between the table board 11 and the exhaust hood 12, and the operation window and the operation space left between the table board 11 and the exhaust hood 12 are sealed. At this time, the spring 33 pushes the pedal 31 upward. When a chemical experiment is required, the control component 3 is stepped on, and the control component 3 and the protective plate 2 are switched up and down, so that the protective plate 2 is lifted up, and the operation window between the table board 11 and the exhaust hood 12 is opened; S2, the operator will continue to stand on the control assembly 3, set up the partition 4 and the experimental equipment 5 located above the table 11, turn the partition 4 90 degrees along the ball joint 45 or the X-axis or Y-axis direction, support the erected mounting plate 41 through the second electric push rod 47, set up support frames 43 at different positions on the mounting plate 41 according to the experimental content, fix the experimental equipment 5 on the support frame 43, so that the experimental equipment 5 forms an experimental scale; S3.

Flasks are often needed in the experiment to heat and react various experimental supplies. The flasks are usually placed on an iron frame for heating and reaction. When an accidental explosion or a large amount of heat is generated in the experiment, the operator only needs to step back and step down from the control component 3 to lift the spring 33 upward. At this time, the protective plate 2 falls downward quickly to separate the operator from the operating table, which can prevent the user from being injured. At the same time, the solution and equipment fragments produced by the explosion fall directly from the through hole of the card slot 16 into the cavity at the bottom of the table top 11, preventing the chemicals in the chemical experiment from destroying the experimental table during violent reactions. The content not described in detail in this description belongs to the prior art known to professional and technical personnel in this field.
