Description

Technical Field

[0001] This utility model belongs to the field of chemical experiments, specifically a multifunctional experimental platform for chemical experiments. Background Technology

[0002] As an indispensable basic equipment in chemical experiments, the experimental bench plays an important role in placing experimental instruments and carrying out experimental operations. The cleaning and maintenance of the experimental bench is directly related to the safety and efficiency of the experiment.

[0003] In chemical experiments, it is common for solutions to spill from test tubes onto the lab bench. During experiments, when handling low-concentration, non-corrosive conventional solutions (such as dilute salt water or water), lab personnel often fail to wear gloves due to convenience or oversight. If spillage occurs, personnel often directly wipe it up with absorbent paper, lint-free cloths, or special cloths. This method has significant drawbacks: even solutions initially deemed safe may possess potential corrosiveness or toxicity due to misjudgment of concentration or impurities. Direct contact with these solutions greatly increases the risk of burns or poisoning for lab personnel, reducing the safety of the experiment.

[0004] To address the problems raised in the background art, those skilled in the art have proposed a multifunctional experimental platform for chemical experiments. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides a multifunctional experimental table for chemical experiments.

[0007] The cleaning mechanism includes a movable plate disposed between two baffles. A handle is slidably disposed on the movable plate. A mounting plate is disposed at the bottom of the handle. Two symmetrically distributed springs are sleeved on the outside of the handle. The two ends of the springs are respectively connected to the mounting plate and the movable plate. A connecting plate is disposed at the bottom of the mounting plate. A cleaning component is disposed at the bottom of the connecting plate.

[0008] Preferably, the upper part of the baffle is provided with a guide groove, and guide blocks are provided on both the front and rear sides of the movable plate. The bottom of the guide block penetrates into the guide groove and is slidably connected to the guide groove.

[0010] Preferably, the upper part of the mounting plate is provided with two symmetrically distributed connecting shafts, and a limit block is rotatably provided on the connecting shaft.

[0011] Preferably, the upper part of the movable plate has two symmetrically distributed limiting ports that match the limiting blocks, and the limiting blocks are located inside the limiting ports.

[0012] Preferably, the storage cabinet has a storage opening at the bottom left end for placing a movable plate.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] 1. This utility model, through its cleaning mechanism, allows for non-contact cleaning of the test bench body when cleaning solutions dripping onto it or cleaning the entire body. By pressing the handle to bring the cleaning component into contact with the test bench surface, and then pushing the moving plate, the test bench surface can be cleaned.

[0023] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of this utility model.

[0024] As attached Figure 1 To be continued Figure 4 As shown:

[0025] This utility model provides a multifunctional laboratory bench for chemical experiments, including a bench body 1. A storage cabinet 2 for storing experimental equipment is provided on the upper right side of the bench body 1. A cleaning tank 3 for cleaning experimental equipment is provided on the upper left side of the bench body 1. Baffles 4 are provided on both the front and rear sides of the upper part of the bench body 1. A cleaning mechanism 5 for cleaning the table surface of the bench body 1 is provided between the two baffles 4.

[0026] When conducting chemical experiments on the test bench body 1, if the test solution drips onto the surface of the test bench body 1, the cleaning mechanism 5 can clean up the dripped solution in time, avoiding the need for the experimenter to directly wipe it with absorbent paper, lint-free cloth or special rag. After the experiment, the cleaning mechanism 5 can also be used to clean the entire surface of the test bench body 1. The operation is simple and convenient, improving the practicality and safety of the test bench body 1.

[0027] refer to Figure 2 and Figure 3 The cleaning mechanism 5 includes a movable plate 51 disposed between two baffles 4. A handle 52 is slidably disposed on the movable plate 51. A mounting plate 53 is disposed at the bottom end of the handle 52. Two springs 54 are symmetrically distributed on the outside of the handle 52. The two ends of the springs 54 are respectively connected to the mounting plate 53 and the movable plate 51. A connecting plate 55 is disposed at the bottom of the mounting plate 53. A cleaning component 56 is disposed at the bottom of the connecting plate 55.

[0028] When cleaning the solution that drips onto the surface of the test bench 1 during the experiment, the experimenter can pull the movable plate 51 from right to left on the test bench 1. When the movable plate 51 moves to the location where the solution drips, the operator can press the handle 52. At this time, the handle 52 can drive the mounting plate 53 to move down. The downward movement of the mounting plate 53 drives the cleaning component 56 to move down through the connecting plate 55 and contact the solution on the surface of the test bench 1. Then, by pushing the movable plate 51 left and right, the cleaning component 56 can be used to clean the dripped solution. After releasing the handle 52, under the elastic reset action of the spring 54, the mounting plate 53 will drive the cleaning component 56 to move up automatically and separate from the surface of the test bench 1, thus avoiding unnecessary wear caused by the cleaning component 56 continuously contacting the surface of the test bench 1 in a non-clean state.

[0029] When the test bench body 1 needs to be cleaned after the experiment, the handle 52 can be pressed to keep the cleaning component 56 in contact with the test bench body 1. Then, the moving plate 51 can be pushed to move smoothly along the length of the baffle 4, and the test bench body 1 can be wiped clean by the cleaning component 56.

[0030] It should be noted that the cleaning component 56 and the connecting plate 55 are designed to be detachable, for example, by using Velcro or clips to fix them to the bottom of the connecting plate 55; at the same time, the cleaning component 56 can be absorbent paper, lint-free cloth or special cloth.

[0031] refer to Figure 2 The upper part of the baffle 4 is provided with a guide groove 6, and the front and rear sides of the movable plate 51 are provided with guide blocks 7. The bottom of the guide block 7 penetrates into the guide groove 6 and is slidably connected with the guide groove 6.

[0032] When the moving plate 51 moves, it will drive the guide block 7 to move within the guide groove 6, which can prevent the moving plate 51 from shifting, tilting or getting stuck, thus ensuring the cleaning effect of the cleaning component 56 on the test bench body 1.

[0033] refer to Figure 3 The bottom of the mounting plate 53 is provided with a mounting groove 8, and the connecting plate 55 is slidably disposed in the mounting groove 8. The vertical cross-section of both the mounting groove 8 and the connecting plate 55 is T-shaped, and the front and rear sides of the connecting plate 55 are in contact with the corresponding baffles 4 respectively.

[0034] refer to Figure 2 and Figure 4 The upper part of the mounting plate 53 is provided with two symmetrically distributed connecting shafts 9, and a limit block 10 is rotatably provided on the connecting shafts 9.

[0035] refer to Figure 2 The upper part of the movable plate 51 has two symmetrically distributed limiting ports 11 that match the limiting block 10, and the limiting block 10 is located inside the limiting port 11.

[0036] When the mounting plate 53 moves downward, it causes the limiting block 10 to slide within the limiting port 11. During this process, the limiting block 10 does not disengage from the limiting port 11, so releasing the handle 52 will not affect the normal reset of the mounting plate 53. When the cleaning part 56 needs to be replaced periodically, pulling the handle 52 upward causes the mounting plate 53 to move upward. The upward movement of the mounting plate 53 causes the cleaning part 56 on the connecting plate 55 to move upward, so that the cleaning part 56 moves out between the two baffles 4. At this time, the spring 54 is compressed. At the same time, the limiting block 10 also moves upward and moves out of the limiting port 11. Then, the limiting block 10 is rotated to ninety degrees. After releasing the handle 52, the elastic force of the spring 54 will cause the limiting block 10 to abut against the upper surface of the moving plate 51, thereby limiting the mounting plate 53 and preventing it from moving downward. At this time, the experimenter can push the connecting plate 55 to slide along the mounting groove 8 and slide out of the mounting groove 8, thus facilitating the replacement of the cleaning part 56.

[0037] refer to Figure 1 The bottom left end of the storage cabinet 2 has a storage opening 12 for placing the movable plate 51.

[0038] When not performing cleaning operations, the experimenter can push the movable plate 51 into the storage opening 12, so that the movable plate 51 is stored at the bottom of the storage cabinet 2, avoiding its exposure above the table surface of the test bench body 1 and occupying the operating space, ensuring the integrity of the table surface area of ​​the test bench body 1 during the experiment, and providing sufficient range of motion for various chemical experimental operations.

[0039] refer to Figure 1 The upper part of the cleaning tank 3 is sloping all around.

[0040] When the experimenter uses the cleaning component 56 to clean the surface of the test bench body 1, the ramp can easily push the residual experimental waste liquid, scattered solid reagent residues, and sewage generated during the cleaning process onto the surface of the test bench body 1 into the cleaning tank 3.

[0041] Working principle: When conducting a chemical experiment on the test bench body 1, if a solution drips onto the surface of the test bench body 1, the experimenter pulls the movable plate 51 out of the receiving port 12, then pushes the movable plate 51 to the location where the solution dripped. Pressing the handle 52 on the movable plate 51 causes the mounting plate 53 to move down. The mounting plate 53, through the connecting plate 55, causes the cleaning component 56 to move down and contact the solution on the surface of the test bench body 1. Pushing the movable plate 51 left and right allows the cleaning component 56 to clean up the dripped solution. Releasing the handle... After the handle 52 is pressed, under the elastic reset action of the spring 54, the mounting plate 53 drives the cleaning component 56 to move automatically upward and separate from the table surface of the test bench body 1, avoiding unnecessary wear of the cleaning component 56. When the table surface of the test bench body 1 needs to be cleaned after the experiment, keep the handle 52 pressed so that the cleaning component 56 is always in contact with the table surface, and push the moving plate 51 to move smoothly along the length direction of the baffle 4. The table surface of the test bench body 1 can then be wiped thoroughly by the cleaning component 56. Thus, the experimenter is less likely to come into contact with the solution during the cleaning process, which improves the safety of the experiment.

[0042] When the cleaning part 56 needs to be replaced periodically, pull the handle 52 upward to move the mounting plate 53 upward. The upward movement of the mounting plate 53 moves the connecting plate 55 and the cleaning part 56 upward and compresses the spring 54. At the same time, the limiting block 10 moves upward and moves out of the limiting port 11. After rotating the limiting block 10 to ninety degrees, release the handle 52. Under the elastic force of the spring 54, the limiting block 10 and the upper surface of the moving plate 51 abut against the mounting plate 53 to limit its downward movement. At this time, the experimenter can push the connecting plate 55 out of the mounting groove 8 to complete the replacement of the cleaning part 56, which is simple and convenient.
