Specific embodiment

It is noted that following detailed description is all illustrative, it is intended to provide further instruction to the application.Unless another It indicates, all technical and scientific terms used herein has usual with the application person of an ordinary skill in the technical field The identical meanings of understanding.

It should be noted that term used herein above is merely to describe specific embodiment, and be not intended to restricted root According to the illustrative embodiments of the application.As used herein, unless the context clearly indicates otherwise, otherwise singular Also it is intended to include plural form, additionally, it should be understood that, when in the present specification using term "comprising" and/or " packet Include " when, indicate existing characteristics, step, operation, device, component and/or their combination.

As background technique is introduced, irregular glassware cannot effectively be cleaned not by existing in the prior art Foot, in order to solve technical problem as above, present applicant proposes a kind of flask cleaning brush for laboratory.

In a kind of typical embodiment of the application, as Figure 1-Figure 4, a kind of flask for laboratory is provided Cleaning brush, including push rod 3, motion bar 6, swipe 4, brush block, throw-out collar 2 and handle 1,6 surface of motion bar are equipped with screw thread 8, push away The threaded hole matched with 6 surface screw thread 8 of motion bar is equipped with inside bar 3, motion bar 6 is threadedly coupled with push rod 3.

Push rod 3 is to backspin, and motion bar 6 is opposite to shorten, and push rod 3 revolves upwards, and motion bar 6 is relatively elongated, can be suitable for not With the cleaning of the round-bottomed flask of model.

Circumferentially multiple swipes 4 for being used to form cleaning sphere 9,4 one end of swipe are connected motion bar 6 with throw-out collar 2, brush 4 other end of item is connected with motion bar 6.

The swipe 4 is arc-shaped.

In some embodiments, circumferentially six swipes 4 of motion bar 6.

Further, 6 bottom of motion bar opens up threaded hole 10, and motion bar 6 and swipe 4 are by being installed in threaded hole 10 Bolt 11 is fixed.

Throw-out collar 2 is sheathed on the outer circumferential of push rod 3, and throw-out collar 2 is equipped with close to the connecting pin of push rod 3 and motion bar 6 and is used for Clean the brush block of flask neck inner wall.

3 surface of push rod, which is equipped with, penetrates through its internal hole, and the swipe 4 passes through hole and protrudes on the inside of throw-out collar 2 admittedly It is fixed.
