Abstract
The utility model relates to a test-tube brush applied to multiple test tubes in a chemical laboratory. The test-tube brush comprises a handle, a left brush piece, a right brush piece and a spring. The test-tube brush is characterized in that the left brush piece and the right brush piece are arranged on the handle, the spring is arranged between the left brush piece and the right brush piece, and the tail end of the left brush piece is arc-shaped. The spring is utilized to change the distance between the two brush pieces, so that the test-tube brush can adapt to the test tubes with different sizes. When the test-tube brush is used, the two brush pieces are pressed to insert into a test tube, the spring is expanded to enable the brush pieces to closely cling to the wall of the test tube, the handle is rotated right and left and is pulled up and down, and then the wall of the test tube wall is brushed; and the tail end of the left brush piece is bent to be arc-shaped, and thus the test-tube brush can be used for brushing the semi-spherical bottom of the test tube. The test-tube brush provided by the utility model is ingenious in design, simple to manufacture and low in cost, and has a good test tube brushing effect; more importantly, the one brush can brush the test tubes with different sizes, so that the device allocation of the laboratory is saved; and the test-tube brush does not need to be changed when being used for brushing the test tubes with different sizes, and thus the test-tube brush is convenient to use.
Description
Technical field
The utility model relates to a kind of chemical experimental instrument cleaning means, is specially a kind of chemical laboratory multitube and uses test-tube brush.
Background technology
Test tube is the most frequently used instrument in the chemical experiment, needs after using to clean with test-tube brush at every turn, and using maximum at present is the straight rod type test-tube brush.Because test tube has different specifications, so the laboratory has been equipped with the straight rod type test-tube brush that varies in size, is used for scrubbing the test tube that varies in size respectively.This Boiling tube is with big brush, and small test tube has not only increased breadboard equipment configuration with the phenomenon of little brush, when the test tube that cleaning varies in size, wants to use test-tube brush instead, and it is also inconvenient to operate.
Summary of the invention
The purpose of the utility model provides a kind of chemical laboratory multitube and uses test-tube brush, realizes that only needing to be equipped with a test-tube brush just can scrub the test tube that varies in size.
Technical solution: comprise handle, left side brush sheet, right brush sheet and spring in the utility model, left side brush sheet and right brush sheet are set on the handle, between left side brush sheet and the right brush sheet spring is set, left side brush sheet end is bent into arc.The cross section of left side brush sheet and right brush sheet is an arc, and bristle is set on it.
Between left side brush sheet and right brush sheet, be provided with spring in the utility model, two brush sheets are splayed and open, and utilize the elasticity of spring to change two brush distance between commutator segments, thereby can adapt to the test tube that varies in size.With hand sheet is brushed on a left side during use and mediated in the insertion test tube with the right sheet of brushing, make the brush sheet be close to inboard wall of test tube through the spring expansion, the left rotation and right rotation handle reaches and spurs handle up and down then, just can scrub inboard wall of test tube.Because the end of left side brush sheet is bent into arc, can scrub the domed bottom of test tube, that so just can put in place scrubs inboard wall of test tube comprehensively, does not stay the dead angle.
The utility model design is ingenious, and making is simple and cost is low, and it is effective to scrub test tube; The most important thing is that a brush just can scrub the test tube that varies in size; Practiced thrift the laboratory equipment configuration, when scrubbing the test tube that varies in size, need not use test-tube brush instead, used easily.

Fig. 1 is the structural representation of the utility model.
The specific embodiment
Embodiment: as shown in fig. 1, comprise handle 1, left side brush sheet 2, right brush sheet 3 and spring 4 in the utility model, left side brush sheet 2 and right brush sheet 3 are set on the handle 1, between left side brush sheet 2 and the right brush sheet 3 spring 4 is set, left side brush sheet 2 ends are arc.The cross section of left side brush sheet 2 and right brush sheet 3 is an arc, and bristle is set on it.
With hand sheet 2 is brushed on a left side during use and mediated in the insertion test tubes with the right sheet 3 of brushing, make the brush sheet be close to inboard wall of test tube through spring 4 expansions, left rotation and right rotation handle 1 reaches and spurs handle 1 up and down then, just can scrub inboard wall of test tube.Because the end of left side brush sheet 2 is bent into arc, can scrub the domed bottom of test tube, that so just can put in place scrubs inboard wall of test tube comprehensively, does not stay the dead angle.
