Description

Fixing device for extraction

Technical Field

The utility model relates to a laboratory support technical field especially relates to a fixing device is used in extraction.

Background

Extraction, also known as solvent extraction or liquid-liquid extraction, is an experimental procedure for separating mixtures by utilizing the different solubilities of different components in a solvent. The method is widely applied to the industries of chemistry, metallurgy, food and the like, particularly the most common experimental operation in an organic chemistry laboratory, and is used for enriching, separating and purifying compounds.

The existing fixed support for extraction generally only has one fixed ring for storing an extraction separating funnel, and the whole experiment can be completed by adding a sample and an extracting agent into the separating funnel, shaking the sample and the extracting agent evenly, standing the mixture for separation and the like, and sometimes even by extracting the mixture for many times. When the liquid is mixed, the separating funnel needs to be taken down and shaken, and then the separating funnel is put back into the fixed ring again for standing, so that the operation is troublesome. In order to improve the working efficiency and avoid the back-and-forth movement of experimenters, a plurality of extraction supports are often needed, the occupied area is large, and the inconvenience is brought to the experiment. In addition, the existing extraction device has poor support fixing stability, and the separating funnel and the beaker are easy to displace due to external shaking.

SUMMERY OF THE UTILITY MODEL

In order to solve the problems, the technical scheme provides a fixing device for extraction.

In order to achieve the purpose, the technical scheme is as follows:

a fixing device for extraction comprises a chassis and a supporting shaft rotatably arranged on the chassis, wherein a plurality of clamping parts are clamped on the supporting shaft, a cross arm is arranged on each clamping part, and a plurality of accommodating cavities for accommodating equipment are formed in the cross arm.

In some embodiments, the supporting shaft is provided with a plurality of through holes in the vertical direction, and the inner wall of the clamping part is provided with a positioning insertion shaft matched with the through holes.

In some embodiments, the clamping portion includes a first clamping member and a second clamping member, the first clamping member and the second clamping member are hinged to each other, a rotating shaft is disposed at the hinged position, the rotating shaft is in friction fit with the first clamping member, and a torsion spring is disposed between the rotating shaft and the first clamping member.

In some embodiments, a toggle piece is arranged at the upper end of the rotating shaft.

In some embodiments, the accommodating cavity is provided with a step, and the step can be matched with baffles with different apertures.

In some embodiments, the first and second clamp members are of arcuate design.

The beneficial effect of this application does:

this application rotates the instrument of equidirectional not through the back shaft that rotates the setting in order to conveniently get the instrument, thereby secondly can dismantle area occupied less through the xarm of centre gripping design to can also the different positions of centre gripping let different instruments take out with laying the high convenience of difference according to the frequency of use, because the xarm has a plurality of chambeies that hold at last, can lay a batch of instrument that the experiment used, thereby reduce personnel and make a round trip to walk about, improved the experimental efficiency.
