Abstract

The utility model belongs to the technical field of laboratory equipment, and relates to a telescopic volumetric flask brush which comprises a hanging ring, a telescopic brush rod, a brush head and brush hair. The brush rod has scalability, so that volumetric flasks with different heights can be conveniently cleaned; the hanging ring is arranged at the upper end, so that the hanging ring is convenient to hang when in idle; the brush head comprises 6 zigzag linear structures made of stainless steel or plastic, two ends are tightly bound to form a deformable cavity, the upper end of the brush head is fixed at the lower end of the brush rod, and volumetric flasks with different diameters can be cleaned by adjusting the extending angle of the brush rod and controlling the shape of the cavity of the brush head; in addition, the cleaning device is also suitable for cleaning rotary evaporation bottles, measuring cylinders, test tubes, beakers and the like with different specifications, and can be used for one brush for multiple purposes.

Description

Telescopic volumetric flask brush

Technical Field

The utility model belongs to the technical field of laboratory equipment, relates to a telescopic volumetric flask brush, and particularly relates to a multifunctional laboratory brush capable of being brushed.

Background

Volumetric flasks are a common analytical instrument in the laboratory, and their washing step plays a vital role for experimental analysis. The volumetric flask brushes which are frequently used at present have no telescopic design, so that volumetric flasks with different specifications are inconvenient to clean; the brush head is generally smaller, and the brush head is not easy to thoroughly clean after entering the bottle; or the brush head is bigger and is not easy to extend from the narrow opening, thereby greatly reducing the cleaning efficiency. There is a need for a volumetric flask brush with adjustable length and brush head shape to improve the cleaning efficiency of laboratory personnel.

Disclosure of Invention

The utility model has the advantages of providing a telescopic volumetric flask brush, in particular to a laboratory brush with adjustable length and brush head shape and multiple functions.

In order to achieve the functions, the utility model relates to a telescopic volumetric flask brush which is characterized by comprising four parts, namely a hanging ring (1), a telescopic brush rod (2), a brush head (3) and brush hair (4).

Wherein the hanging ring (1) is connected with the upper end of the telescopic brush rod (2);

the telescopic brush rod (2) has scalability and can be suitable for cleaning volumetric flasks with different heights;

the brush head (3) comprises 6 zigzag linear structures, two ends are tightly bound to form a deformable cavity, the upper end of the brush head (3) is fixed at the lower end of the telescopic brush rod (2), and the cleaning effect can be improved by adjusting the extending angle of the telescopic brush rod (2) and controlling the shape of the cavity of the brush head (3);

the periphery and the bottom of the brush head (3) are provided with brush hair (4);

the 6 zigzag linear structures of the brush head (3) are made of stainless steel or plastic materials.

The beneficial effects are that: the utility model relates to a telescopic volumetric flask brush, which can adapt to volumetric flasks of different types and improve cleaning efficiency by adjusting the extending length and angle of a brush rod and the shape of a cavity of a brush head when a laboratory worker uses the telescopic volumetric flask brush. When the cavity of the brush head is deformed, the brush head can also be used for cleaning a measuring cylinder, a test tube, a beaker and the like, and can be used for one brush for multiple purposes. The utility model has simple structure, convenient use and low cost, and is suitable for popularization and application.

Detailed Description

The principles and features of the present utility model are described below with reference to the drawings, the examples are illustrated for the purpose of illustrating the utility model and are not to be construed as limiting the scope of the utility model.

Example 1

When the volumetric flask is required to be cleaned, the length of the brush rod can be adjusted firstly, then the brush rod is slowly placed into the volumetric flask, the cavity of the brush head is contracted firstly, and the neck of the flask can be cleaned; with the brush head penetrating into the bottle bottom, the brush head cavity expands to a certain extent, at the moment, the extending length and angle of the brush rod and the shape of the brush head cavity can be adjusted, the cleaning area is increased, and the thorough cleaning of the volumetric flask is facilitated. After the cleaning is completed, the device is taken out.

The above examples are provided for the purpose of illustrating the utility model and are not intended to be limiting; it should be noted that various changes and modifications could be made by one of ordinary skill in the art without departing from the scope of the inventive concept, which would fall within the scope of the present utility model; therefore, all equivalent changes and modifications to the scope of the claims should be covered by the claims.
