Abstract

The utility model discloses a damaged test -tube brush of glass instrument in time of preventing to wash, included supporting role's iron wire pole, the one end of iron wire pole is provided with thin brush silk all around along it, and the end department rigid coupling that sets up thin brush silk at the iron wire pole has the rubber packing ring. The utility model discloses the glass instrument is teared to the iron wire that can effectively prevent the test -tube brush top, through setting up the thin brush silk that length is different with the diameter, enable the residual sanitization of test tube bottom, through setting up the magnet piece, can conveniently fix on the test bench.

Description

A kind of test-tube brush of glass apparatus breakage when can prevent from cleaning

Technical field

The utility model belongs to laboratory apparatus technical field, is specifically related to a kind of test-tube brush of glass apparatus breakage when can prevent from cleaning.

Background technology

In chemical experiment, clean all will use test-tube brush to various glass apparatus, it is a kind of application hairbrush product widely, mainly makes skeleton by iron wire or steel wire, and above with many marshallings, the thin brush silk outwards stretched is formed.Brush wire material has nylon yarn, fiber hair, bristles, steel wire, copper wire, abrasive filaments etc., has the different scopes of application respectively.This equipment in use Problems existing is: when it is used for cleaning glass apparatus, sometimes firmly excessive, the iron wire (steel wire) on test-tube brush top can poke glass apparatus, particularly when cleaning test tube, and be fixed by steel wire winding due to the thin brush silk of test-tube brush, this makes dense degree of test-tube brush whole body brush silk distribution the same, but test-tube brush top brush silk is obviously partially rare, like this when cleaning test tube, the residue bottom test tube is difficult to clean up.

Utility model content

The purpose of this utility model is to provide a kind of test-tube brush of glass apparatus breakage when can prevent from cleaning, and solves existing test-tube brush easily pokes glass apparatus problem when cleaning test tube.

The technical scheme that the utility model adopts is, a kind of test-tube brush of glass apparatus breakage when can prevent from cleaning, comprise passive iron wire bar, one end of iron wire bar is provided with along its surrounding carefully brushes silk, and the end arranging thin brush silk at iron wire bar is connected with rubber washer.

Feature of the present utility model is also,

Thin brush silk reduces gradually along iron wire bar radial direction diameter.

Thin brush silk comprises long filament and short silk, and the length of long filament is 1 ~ 2cm, and the length of short silk is 0.5 ~ 0.9cm.

One end that iron wire bar does not arrange thin brush silk is connected with circular magnet block.

The beneficial effects of the utility model are, a kind of test-tube brush of glass apparatus breakage when can prevent from cleaning, by arranging rubber washer in the end of iron wire bar, can effectively prevent the iron wire on test-tube brush top from poking glass apparatus; By arranging the length thin brush silk different with diameter, the residue bottom test tube can be made to clean up; By arranging magnet piece, can be fixed on testing stand easily.

Accompanying drawing explanation

The structural representation of Fig. 1 test-tube brush of glass apparatus breakage when to be that the utility model is a kind of can prevent from cleaning;

Fig. 2 is the structural representation of thin brush silk in the utility model.

In figure, 1. magnet piece, 2. iron wire bar, 3. rubber washer, 4. carefully brush silk.

Detailed description of the invention

Below in conjunction with the drawings and specific embodiments, the utility model is described in detail.

As shown in Figure 1, a kind of test-tube brush of glass apparatus breakage when can prevent from cleaning, comprise passive iron wire bar 2, one end of iron wire bar 2 is provided with thin brush silk 4 along its surrounding, and the end arranging thin brush silk 4 at iron wire bar 2 is connected with rubber washer 3; One end that iron wire bar 2 does not arrange thin brush silk 4 is connected with circular magnet block 1.As shown in Figure 2, thin brush silk 4 reduces gradually along iron wire bar 2 radial direction diameter; Thin brush silk 4 comprises long filament and short silk, and the length of long filament is 1 ~ 2cm, and the length of short silk is 0.5 ~ 0.9cm.

Using method of the present utility model is, during the glass apparatus such as cleaning test tube, hold this device iron wire bar 2, insert test tube, then the 4 pairs of test tube tube wall cleanings of thin brush silk are utilized, when this device is inserted into test tube bottom, rubber washer 3 can play cushioning effect, prevent test tube from breaking, by the thin brush silk 4 that length is different with diameter, the residue bottom test tube can be made to clean up, by the shape of will carefully brush silk and be designed to reduce gradually along iron wire bar 2 radial direction diameter, the contact force of thin brush silk and tube wall can be strengthened, thus more thoroughly clean up; After finishing using, utilize the magnet piece 1 of iron wire bar 2 tail end, be fixed on testing stand easily, prevent landing.
