Abstract

The utility model relates to a novel safe test tube brush, which is composed of a brush head, a brush holder support and a brush holder. The brush head is a product made of elastic material, and is connected with the brush holder support into a whole body, the other end of the brush holder support is connected with the brush holder, and the brush hairs is arranged on the brush holder support. Through the utility model, not only the breakage condition of the test tub brush to the test tub can be improved, but also the brush holder support which is the easiest to be abraded can be replaced, in addition, because of the existence of the brush holder, the comfort of holding the test tube brush with handa during the test tube washing can be improved.

Description

A kind of new type of safe test-tube brush

Technical field

The utility model relates to a kind of breadboard implement that is used for, especially a kind of hairbrush that is used to clean test tube.

Background technology

Test-tube brush is widely used in universities and colleges, enterprise or the scientific research institution laboratory of industries such as relating to chemistry, chemical industry, biology, medicine, food, environment, is the essential product that test tube and vessel are cleaned in the laboratory.Up to now, the test-tube brush that generally use in the laboratory is to be made by iron wire and bristle, this test-tube brush uses the defective of following several respects: 1. after this test-tube brush uses a period of time, bristle will come off and cause iron wire exposed, be easy to the test tube bursting when cleaning test tube, promptly the service life of this type of test-tube brush is shorter; 2. owing to do not possess special brush holder, the comfort level of therefore holding test-tube brush is bad, and in addition, in use iron wire is easy to get rusty, bend, so cleaning performance will be affected.

Technology contents

The utility model is at the prior art deficiency, and a kind of comfortable test-tube brush that increases the service life simultaneously simple in structure, easy to use is provided.

For reaching above purpose, the test-tube brush that the utility model provides comprises brush, brush holder support, brush holder and bristle, and described brush holder support one end is connected with a brush that is made by elastomeric material, the other end then connects a brush holder, and bristle is arranged on described brush holder support and the brush.

Described brush is to emit to cover the shape product, because brush has elasticity, so it can directly be set on the brush holder support.As everyone knows, in use the rapid wear of test-tube brush partly is a front end, after test-tube brush uses a period of time, the bristle of front end will partly come off, emitting of being made covered the shape product because the test-tube brush brush that provides of the utility model is an elastomeric material, have certain flexibility, even if therefore brush exposes out, can be when cleaning test tube easily with the test tube bursting yet; In addition because the utility model also possesses special brush holder, therefore, comfortable feel but also conveniently exert all one's strength not only when cleaning test tube.

Described brush holder support is cylindric, and the tapered shape of described brush holder and brush is for carving the type projection; No matter brush holder support, brush holder still be brush can be cavity, also can be solid; When the cross section of brush holder support during greater than the cross section of brush holder and the narrow end of brush, brush holder support just is a cavity cylinder, and brush holder and brush are filled in respectively in the brush holder support till can not moving again; When the narrow end section of brush holder and brush during greater than brush holder support, brush holder and brush should be cavity, and then fill in the two ends of brush holder support respectively in brush holder and the brush this moment.Hence one can see that, and the dismounting of brush holder support, brush and brush holder is very convenient, can change at any time when brush holder support and brush have when damage.

For making brush more firm with being connected of brush holder support respectively, projection and the draw-in groove that cooperatively interacts can be set between brush and brush holder support and brush holder and brush holder support respectively with brush holder.

The elastomeric material of described making brush is an elastic caoutchouc.

The specific embodiment

For realizing technical problem to be solved in the utility model, further concrete understanding the technical solution of the utility model below will be with regard to most preferred embodiment of the present utility model and with detailed explanation.

As shown in Figure 1, the utility model comprises brush holder support 1, bristle 2, brush 3 and brush holder 6, brush holder support 1 is a hollow cylinder, 3 of brushes are to emit to cover the shape product, be made by elastic caoutchouc, can directly be set in an end of brush holder support 1, brush holder 6 is tapered, be to carve the type projection, the sectional area in its narrow cross section 5 is less than the cross section 4 of brush holder support 1, therefore, the narrow cross section end 5 of brush holder 6 directly can be filled in the brush holder support 1, till can not moving on, more firm for guaranteeing this connected mode in addition, the narrow cross section end 5 of brush holder 6 is provided with a projection 8, and the corresponding position also is provided with the shrinkage pool that matches with described projection 8 on the brush holder support 1, and bristle 2 is arranged on brush holder support 1 and the brush 3.

Can realize goal of the invention of the present utility model: a. by above technical scheme and cover the shape product because brush 3 is emitting of being made of an elastic caoutchouc, then its front end is smoother, shape and test tube are similar, therefore be that test-tube brush that convenient the utility model provides uses after a period of time the bristle 2 on its brush 3 to come off to cause brush 3 is exposed also can not cause cleaning test tube time bursting test tube, thereby reduce wash the frequency of broken test tube and to prevent to wash test tube people's hand injured, the service life of also promptly having improved test-tube brush; B. because brush holder 6 is to carve the type projection, therefore compared with prior art, the comfort level increase of holding test-tube brush is self-evident; C. well-known, test-tube brush is more flimsy to be the leading portion part, especially brush, therefore, because the test-tube brush brush 3 that provides of the utility model is one directly to be socketed on elastic caoutchouc on the brush holder support 1 and to emit and cover the shape product, so can be only after it damages changing brush head more, utilize again and the purpose of economical with materials use thereby reach.

In sum, practicality of the present utility model is unquestionable, and in addition, above-described only is a preferred embodiment of the present utility model, and is non-so limit to scope of patent protection of the present utility model.So the simple and easy modification or the equivalent structure transformation that use the utility model specification and accompanying drawing to do such as all should in like manner be contained in scope of patent protection of the present utility model.
