Abstract
Description
Technical Field
[0001] The utility model relates to a quantitative material taking device, in particular to a quantitative material sampler for a laboratory. Background Art
[0002] As is well known, the precise quantitative method of materials is to take them out with a small spoon from a storage bottle, then weigh them on a balance, and then add or take out a small amount on the balance to achieve the purpose of precise quantification. Of course, if it is a precise chemical analysis, this method is the most reliable. However, if it is a relatively rough qualitative analysis, there is no need to be so precise. The current existing technology uses a quantitative spoon, which has the advantages of convenient operation and time saving, but the accuracy of material taking with the quantitative spoon is too poor, and sometimes the purpose of qualitative experiments cannot be achieved. Therefore, designing a quantitative material sampler for a laboratory with relatively high precision is a technical problem that needs to be solved currently. Summary of the Invention
[0003] The technical problem to be solved by the utility model is to provide a quantitative material sampler for a laboratory with relatively high precision.
[0004] The technical solution for the utility model to solve its technical problem is:
[0005] The quantitative material sampler for a laboratory includes a cylindrical outer shell, a conical funnel is arranged on the inner wall of the cylindrical outer shell, a small straight tube is arranged at the lower end of the conical funnel, an upper pull-out partition plate and a lower pull-out partition plate with a certain distance are arranged on the small straight tube, and the volume of the space enclosed by the lower surface of the upper pull-out partition plate, the upper surface of the lower pull-out partition plate and the inner wall of the small straight tube is a standard volume quantitative unit of the quantitative material sampler for a laboratory.
[0006] As a preferred scheme of the utility model, it further includes a cover, and an automatic air inlet valve is arranged on the cover.
[0007] As a preferred scheme of the utility model, the cylindrical outer shell is provided with openings matching the upper pull-out partition plate and the lower pull-out partition plate. There are an upper partition plate pull-out limit slideway corresponding to the upper pull-out partition plate and a lower partition plate pull-out limit slideway corresponding to the lower pull-out partition plate on the inner wall of the cylindrical outer shell. Limit protrusions are arranged at the tail ends of the upper pull-out partition plate and the lower pull-out partition plate, and arc-shaped handles are arranged at the heads of the upper pull-out partition plate and the lower pull-out partition plate.
[0008] As a preferred scheme of the utility model, a material receiving bucket slideway with a limiting plate is arranged at the lower part of the small straight tube. A material receiving bucket with a handle is arranged on the material receiving bucket slideway, and a material receiving bucket extraction port is arranged on the cylindrical outer shell.
[0009] The using method of the utility model:
[0010] First, in the original state of the utility model, both the upper pull-out partition plate and the lower pull-out partition plate are in the closed state. When taking materials, first open the upper pull-out partition plate, and then close the upper pull-out partition plate; then open the lower pull-out partition plate, and the materials fall into the material receiving bucket. Finally, take out the material receiving bucket. After use, place the material receiving bucket back in place.
[0011] Compared with the prior art, the utility model has more accurate quantification and convenient operation. BRIEF DESCRIPTION OF THE DRAWINGS
