Detailed Description

Referring to fig. 1, the extraction rack comprises a round base 1, a support rod and a rack plate, wherein the support rod is vertically arranged on the top surface of the round base 1, and the rack plate is arranged at the upper end of the support rod; in the vertical direction, funnel placing holes 31 are distributed on the circumference of the frame plate; below the funnel placing holes 31, a placing table is arranged on the round base 1 in the vertical projection of every other funnel placing hole 31, and the sectional area of the top of the placing table is larger than that of the bottom of the placing table. If the number of funnel placing holes 31 is singular, the number of placing tables is rounded downward.

As shown in fig. 3, the shelf board is circular when viewed in the vertical direction, the funnel placing holes are circumferentially distributed, and a total of six funnel placing holes are taken as an example, and an angle of about 270 degrees is left for the experimenter to operate. If the extraction frame among the prior art, the hole linear distribution is placed to the funnel, outwards only 180 spaces supply the experimenter to operate, bumps other experimental facilities on the extraction frame by mistake easily.

The utility model discloses an extraction frame still makes the experimental device of adjacent position of placing on the extraction frame separate the certain distance through the mode of dislocation from top to bottom, reserves great space, and the experimenter has sufficient space to operate. The sectional area of the top of the placing table is larger than that of the bottom of the placing table, so that equipment with the lower part larger than the upper part, such as a conical flask and a flask, is suitable to be placed on the round base. When putting experimental apparatus, the big equipment in lower part ratio upper portion of erlenmeyer flask, flask to and the prior direct placing on round bottom seat 1 of the slender equipment of test tube, colour comparison tube class, shorter equipment such as beaker is preferred to be put on placing the platform, and the dislocation is put and to be had enough space and make things convenient for people's hand to reach the extraction frame within range operation.
