Abstract

The utility model discloses a chemical test tube brush which comprises a handle and a brush head, wherein the brush head comprises a large brush head and a small brush head. One end of the large brush head is fixedly connected with the handle, an inserted hole is formed in the other end of the large brush head, an inserted foot is arranged at one end of the small brush head, the inserted foot inserts into the inserted hole and stretches along the inserted hole, and a cover cap which is used for stopping sewage water in a test tube is arranged between the handle and the brush head. The chemical test tube brush has the technical advantages of being reasonable in design, convenient to use and space-saving.

Description

The chemistry test-tube brush

Technical field

The utility model relates to a kind of chemical apparatuses cleaning means, relates in particular to a kind of chemical test-tube brush.

Background technology

Often use test tube in the chemical experiment, use test tube at every turn after, clean with test-tube brush.Usually test tube has different specifications, so the laboratory has been equipped with the chemical test-tube brush that varies in size, is used for cleaning the test tube of different size respectively, and these test-tube brushes have increased the usage space in laboratory.And traditional test-tube brush is when cleaning test tube, and it is rather hard to rotate test-tube brush, and the sewage in the test tube spills easily, and is very inconvenient.

The utility model content

The purpose of this utility model is to overcome above-mentioned deficiency of the prior art, and a kind of chemical test-tube brush that can clean the different size test tube easily is provided.

For achieving the above object, the technical solution adopted in the utility model is:

A kind of chemical test-tube brush, comprise handle and brush, it is characterized in that, described brush comprises big brush and little brush, described big brush one end is fixedlyed connected with described handle, and the described big brush other end has jack, and described little brush one end has pin, described pin can insert in the described jack and along described jack and stretch, and is useful on the block that stops sewage in the test tube between described handle and the described brush.

Wherein, described handle has the cross rotary head away from an end of described brush.

Wherein, described jack is two.

The utility model has avoided using a plurality of test-tube brushes by the configuration of big or small brush, not only easy to use but also save the space, the sewage that spills with brush in the time of can stopping cleaning by the block between handle and the test-tube brush, cross rotary head by handle end can be rotated test-tube brush convenient and strength-savingly when cleaning, compared with prior art have advantage reasonable in design, easy to use and that save the space.

The specific embodiment

Further specify embodiment of the present utility model below in conjunction with accompanying drawing.

Referring to Fig. 1 to chemical test-tube brush shown in Figure 4, comprise handle 1 and brush 2, brush 2 comprises big brush 3 and little brush 4, big brush 3 one ends are fixedlyed connected with handle 1, big brush 3 other ends have jack 5, little brush 4 one ends have pin 6, and pin 6 can insert in the jack 5 and along described jack 5 and stretch, and jack 5 can be two or three, when needs clean small test tube, according to the degree of depth of small test tube, little brush 4 can be pulled out to the length that needs but not break away from test-tube brush, when needs clean Boiling tube, little brush 4 is taken out from jack 5, clean Boiling tubes with big brush 3, avoided using a plurality of test-tube brushes like this, not only easy to use but also save the space.Block 7 is arranged between handle 1 and the brush 2, can stop the sewage that spills with brush in the test tube when cleaning.Handle 1 has cross rotary head 8 away from an end of brush 2, can rotate test-tube brush when cleaning convenient and strength-savingly.

Claims
