Description

Technical Field

[0001] The utility model relates to a placing rack for glass measuring instruments, in particular to the structure of the placing rack for glass measuring instruments. Background Art

[0002] Glass measuring instruments are commonly used experimental equipment in laboratories, including pipettes, graduated pipettes, burettes, etc. After the experimenter completes operations such as pipetting, measuring, and titrating, in order to prevent the glass measuring instruments from being damaged by knocking and dropping, the used glass measuring instruments need to be gently placed on the placing rack, and cleaned and maintained after the experiment to ensure the accuracy and safety of the experiment.

[0003] Since most of the chemical reagents used in experiments are corrosive, when the glass measuring instruments are placed on the placing rack, since the placing rack cannot collect the residual liquid in the glass measuring instruments, the residual liquid in the glass measuring instruments will automatically drip onto the experimental table and even flow to the ground, causing corrosion of the tabletop of the experimental table, laboratory pollution, and may also be accidentally touched by the experimenter, resulting in skin burns. Moreover, cleaning the residual liquid on the experimental table and the ground will waste a lot of time.

[0004] In addition, since the heights of glass measuring instruments such as pipettes, graduated pipettes, and burettes of different models are different, the existing placing racks can only place glass measuring instruments of the same model or glass measuring instruments with a small height difference, resulting in inconvenient placement of glass measuring instruments of different models.

[0005] The first object of the utility model is to solve the problem that when the glass measuring instrument is placed after use, the residual liquid in the glass measuring instrument will drip onto the experimental table, causing corrosion of the tabletop.

[0006] The second object of the utility model is to solve the problem of inconvenient placement when the existing placing rack places glass measuring instruments of different models. Content of the Utility Model

[0007] In order to solve the above problems, the utility model provides a placing rack for glass measuring instruments, which includes a base 1, a support rod 2 and a liquid collecting groove 3. The support rod 2 is vertically arranged on the base 1. A placing ring 21 for placing the glass measuring instrument is arranged on the support rod 2. The placing ring 21 is arranged on the support rod 2 through a connecting piece 4 that can slide up and down along the support rod 2. The liquid collecting groove 3 is detachably arranged on the base 1 and is located below the placing ring 21.

[0008] The utility model collects the residual liquid dripping from the glass measuring instrument placed on the placing ring 21 through the liquid collecting tank 3, preventing the residual liquid from dripping on the experimental table and the ground, corroding the tabletop of the experimental table and polluting the laboratory. The liquid collecting tank 3 is detachably arranged on the base 1, which can facilitate the removal of the liquid collecting tank 3 for cleaning, ensuring that there is no residue accumulation inside the liquid collecting tank 3 and maintaining the cleanliness and hygiene in the laboratory. The placing ring 21 is arranged on the support rod 2 through a connecting member 4 that can slide up and down along the support rod 2, so that the height of the placing ring 21 can be adjusted to adapt to the placement of glass measuring instruments of different models.

[0009] Preferably, the base 1 is rectangular, a horizontally extending sliding groove 11 is arranged on the front side surface of the base 1, both ends of the sliding groove 11 extend to the left and right ends of the base 1, and a sliding block 31 matching the sliding groove 11 is arranged on the rear side surface of the liquid collecting tank 3. The sliding block 31 is slidably arranged in the sliding groove 11. By arranging the horizontally extending sliding groove 11 on the base 1 and the sliding block 31 on the liquid collecting tank 3, the liquid collecting tank 3 can be slidably connected to the base 1 through the cooperation of the sliding block 31 and the sliding groove 11.

[0010] Preferably, the connecting member 4 includes a connecting block 41 and a locking bolt 42. The connecting block 41 is fixedly connected to the placing ring 21.

[0024] The following will elaborate on the preferred embodiments of the present invention in detail with reference to the accompanying drawings.

[0025] As shown in Figure 1 , Figure 2 and Figure 3 , a glass measuring device placement rack includes a base 1, a support rod 2, and a liquid collecting groove 3. The support rod 2 is vertically arranged on the base 1. A placing ring 21 for placing a glass measuring device is provided on the support rod 2. The placing ring 21 is arranged on the support rod 2 through a connecting piece 4 that can slide up and down along the support rod 2.

[0026] A plurality of support rods 2 are provided. The plurality of support rods 2 are arranged at equal intervals along the extending direction of the base 1. The tops of the plurality of connecting rods 2 are fixedly connected through a connecting rod 22. By providing a plurality of support rods 2 on the base 1, a plurality of glass measuring devices can be placed simultaneously, improving the placement convenience.

[0027] The placement ring 21 is arranged on the support rod 2 through a connecting member 4 that can slide up and down along the support rod 2, so that the height of the placement ring 21 can be adjusted to adapt to the placement of glass measuring instruments of different models.

[0028] The liquid collecting tank 3 is detachably arranged on the base 1 and is located below the placement ring 21. The liquid collecting tank 3 can collect the residual liquid dripping from the glass measuring instrument placed on the placement ring 21, preventing the residual liquid from dripping onto the experimental table and the ground, corroding the desktop of the experimental table and polluting the laboratory.

[0029] Setting the liquid collecting tank 3 to be detachably connected to the base 1 can facilitate the removal of the liquid collecting tank 3 for cleaning, ensuring that there is no residue accumulation inside the liquid collecting tank 3 and maintaining the cleanliness and hygiene of the laboratory.

[0030] As Figure 4 shown, the base 1 is rectangular, and a sliding groove 11 extending horizontally in the left-right direction is arranged on the front side surface of the base 1, and both ends of the sliding groove 11 extend to the left and right ends of the base 1.

[0031] An anti-slip pad (not shown in the figure) is arranged on the bottom surface of the base 1, and the anti-slip pad is made of rubber. Arranging the anti-slip pad on the bottom surface of the base 1 can prevent the base 1 from sliding on the experimental table, making the placement rack unstable and causing the glass measuring instrument to collide and be damaged.

[0032] As Figure 5 shown, a slider 31 matching the sliding groove 11 is arranged on the rear side surface of the liquid collecting tank 3, and the slider 31 can be slidably arranged in the sliding groove 11. By arranging the horizontally extending sliding groove 11 on the base 1 and the slider 31 on the liquid collecting tank 3, the liquid collecting tank 3 can be slidably connected to the base 1 through the cooperation of the slider 31 and the sliding groove 11.

[0033] Handles 32 are arranged at both ends of the liquid collecting tank 3. By arranging the handles 32 at both ends of the liquid collecting tank 3, it is convenient to disassemble, assemble and clean the liquid collecting tank 3.

[0034] As Figure 2 and Figure 6 shown, the connecting member 4 includes a connecting block 41 and a locking bolt 42. The connecting block 41 is fixedly connected to the placement ring 21. An adjustment hole 411 corresponding to the support rod 2 and extending vertically is arranged on the connecting block 41. A threaded hole 412 corresponding to the locking bolt 42 and extending horizontally and communicating with the adjustment hole 411 is arranged on the side surface of the connecting block 41. The connecting block 41 can be slidably sleeved on the support rod 2 through the adjustment hole 411.

[0035] The locking bolt 42 is inserted into the threaded hole 412 to fix the connecting block 41 to the support rod 2.

[0036] Therefore, the connecting block 41 is sleeved on the support rod 2 through the adjusting hole 411, and the locking bolt 42 is inserted into the threaded hole 412 so that the locking bolt 42 abuts against the support rod 2, thereby fixing the connecting block 41 and the support rod 2. Loosening the locking bolt 42 allows the connecting block 41 to slide up and down along the support rod 2, thus adjusting the height of the placing ring 21 to accommodate the placement of glass measuring vessels of different models.

[0037] As Figure 7 shown, when the utility model is in use, according to the height of the burette 5 to be placed, the placing ring 21 on the support rod 2 is adjusted to a suitable height. During adjustment, the locking bolt 42 is loosened to make the connecting block 41 slide up and down along the support rod 2 until the placing ring 21 is at a suitable height, and then the locking bolt 42 is tightened to fix the connecting block 41 and the support rod 2. The burette 5 is placed on the corresponding placing ring 21 so that the residual liquid on the burette 5 drips into the liquid collecting tank 3. When there is more residual liquid in the liquid collecting tank 3, hold the handle 32 on the liquid collecting tank 3 and remove the liquid collecting tank 3 from the base 1 for cleaning.

[0038] By providing the liquid collecting tank 3, the residual liquid dripping from the glass measuring vessel 5 placed on the placing ring 21 can be collected through the liquid collecting tank 3, preventing the residual liquid from dripping onto the experimental table and the ground, corroding the tabletop of the experimental table and polluting the laboratory. The liquid collecting tank 3 is detachably arranged on the base 1, which facilitates the removal of the liquid collecting tank 3 for cleaning, ensuring that there is no residue accumulation inside the liquid collecting tank 3 and maintaining the cleanliness and hygiene of the laboratory. The placing ring 21 is arranged on the support rod 2 through the connecting member 4 that can slide up and down along the support rod 2, thereby adjusting the height of the placing ring 21 to accommodate the placement of glass measuring vessels 5 of different models.

[0039] It should be noted that the above embodiments illustrate the present invention rather than limit the present invention, and those skilled in the art can design alternative embodiments without departing from the scope of the appended claims.
