Test tube brush with replaceable bristles

Abstract

According to the test tube brush with the replaceable bristles, specifically, a plurality of fixing clamping grooves are formed in the side face of a brush head part, strip-shaped clamping strips planted with the bristles are installed in the clamping grooves, and a clamping groove cover planted with the bristles is arranged at the end of the brush head and used for limiting the strip-shaped clamping strips to move outwards. And only the strip-shaped clamping strip or the clamping groove cover at the corresponding position needs to be replaced, so that the use cost is reduced, and the service life of the brush is prolonged.

Description

TECHNICAL FIELD

[0001] The utility model belongs to the experimental vessel cleaning field, especially relates to a test tube brush with replaceable bristles. BACKGROUND

[0002] The test tube brush is a commonly used tool in the laboratory, and is mainly used for brushing the inside of narrow vessels such as test tubes and measuring cylinders after use.

[0003] Most of the existing test tube brushes are integrally formed, and when the bristles are severely worn or have large deformation, the entire test tube brush has to be discarded and replaced. However, the handle part of the test tube brush can be reused, which causes waste. In addition, when the test tube brush is used, the bristles at the lower part are used more frequently than the bristles at the upper part, which causes the bristles at the lower part to be severely worn or have large deformation after the test tube brush is used for a period of time. At this time, the test tube brush cannot brush the inner wall of the test tube and the measuring cylinder well, and the bristles at the upper part of the test tube brush are basically in a new state, which causes the bristles at the brush head part of the test tube brush to not be fully used, resulting in waste. SUMMARY

[0004] The utility model aims at providing a test tube brush with replaceable bristles to solve the problems mentioned in the background art. To achieve this purpose, the specific technical solution is as follows:

[0005] The test tube brush with replaceable bristles is characterized in that the brush head part of the brush is provided with a detachable clamping strip and a clamping groove cover planted with bristles, the clamping strip is inserted into the clamping groove from the brush head end, and the brush head end is provided with a clamping groove cover limiting the movement of the clamping strip out of the clamping groove.

[0006] Further, the clamping strip is installed in the clamping groove.

[0007] The utility model has the advantages of:

[0008] The utility model is characterized in that the brush head part of the brush is provided with a detachable clamping strip and a clamping groove cover planted with bristles, which replaces the brush head part of the traditional brush. When the bristles are severely worn or have large deformation, the clamping strip or the clamping groove cover can be replaced, which reduces the use cost and avoids waste. In addition, when the bristles at the lower part of the clamping strip are severely worn or have large deformation compared with the bristles at the upper part, the clamping strip can be inserted back in the reversed direction after being taken out, which makes the bristles originally located at the upper part be located at the lower part, so that all the bristles on the clamping strip can be fully used, which reduces the use cost and avoids waste.

[0016] The embodiment provides a replaceable brush tube brush. The brush head 2 of the brush 1 is provided with a card slot 3 on one side, and one end of the card slot 3 extends to the end of the brush head 2. A strip-shaped card strip 4 is inserted into the card slot 3 from the end of the brush head 2. The end of the brush head 2 is provided with a detachable card slot cover 5 for limiting the movement of the card strip 4 out of the card slot 3. The card strip 4 and the card slot cover 5 are provided with brushes 6.

[0017] The detachable installation mode between the brush head 2 and the card slot cover 5 can adopt various structures, such as buckle connection, threaded connection, pin connection, magnetic attraction fixation and the like.

[0018] When the brushes 6 are seriously worn or have large deformation, the card strip 4 or the card slot cover 5 can be replaced. In addition, when the brushes 6 at the lower part of the card strip 4 are seriously worn or have large deformation compared with the brushes 6 at the upper part, the card strip 4 can be inserted in the reversed direction after being taken out, so that the brushes 6 originally at the upper part are located below, and all the brushes 6 on the card strip 4 can be fully used.

[0019] Further, a plurality of card strips 4 are installed in the card slot 3. When the brushes 6 on a card strip 4 are seriously worn or deformed, any mode or combination of multiple modes of replacing the card strip 4, adjusting the direction of the card strip 4, and changing the arrangement order of the card strips 4 in the card slot 3 can be used to fully use all the brushes 6 on the card strip 4.
