A liquid quantitative lifting device

Abstract

The invention relates to the technical field of solution preparation, and particularly relates to a liquid quantitative lifting device. The liquid quantitative lifting device comprises an annular positioning block, a quantitative lifting gear, supporting structures and fixing structures. The upper middle part of the annular positioning block is provided with a threaded pedestal. The outside of the threaded pedestal is provided with reinforcing rods in an inclined manner. The side wall of the annular positioning block is provided with first threaded holes in a through manner. The upper end of an extracting cavity is mounted with a trapezoid base. The device achieves quantitative liquid lifting, avoids excessive contact between an operator and a liquid to be extracted before and after using, protects the operator to a certain degree and prevents the liquid to be extracted from excessive contamination. Through a reasonable structure arrangement, the position of the overall device can be maintained well to adapt to different operation environments. Through a separable structure design, an operation process is facilitated. The device has a wide market application prospect.

Description

technical field [0001] The invention relates to the technical field of solution configuration, in particular to a liquid quantitative lifting device.

[0002] In the factory production process and the medical drug configuration process, it is necessary to extract the liquid through a quantitative device to achieve quantitative extraction of the liquid. Whether it is in the laboratory or in the factory, the operation of quantitative extraction is required. Existing When the liquid is quantitatively extracted under the technology, the purpose of quantitatively measuring the liquid is mostly achieved through a quantitative container, such as a measuring cylinder and a measuring cup. However, this quantitative lifting and extraction device requires manual collection of the liquid. For corrosive or hazardous liquids, too much manual operation will seriously affect the quality of the extracted liquid, and will pose a great safety hazard to the operator, affecting the life safety of the operator, and the existing technology The measuring operation is to achieve quantitative lifting of the liquid through the movable measuring instrument, which further reduces the safety, and the traditional lifting device will appear bubbles in the process of measuring the inner wall of the measuring instrument, which will affect the accuracy of measuring the liquid
