Description

Multifunctional test tube brush

technical field

The utility model relates to a cleaning tool for laboratory appliances, in particular to a test tube brush.

Background technique

Experimental equipment plays an important role in realizing the goal of experimental teaching and improving the quality of experimental teaching. At present, manual scrubbing is mostly used in laboratories to scrub test tubes. Test tube brushes are divided into large, medium and small sizes. The waste of water resources and the extension of cleaning time in the cleaning process, in addition, because the small test tube brush is small in size, it is not conducive to storage and use.

Utility model content:

The technical problem to be solved by the utility model is a cleaning brush which is convenient to use and suitable for various experimental instruments, and its specific technical scheme is:

A multifunctional test tube brush, comprising a handle for holding, and a brush head arranged at one end of the handle, the brush head includes a brush rod and bristles integrally formed with the handle, and is also provided with an adjustment buckle and a connecting buckle, The brush rod is provided with a concave ring, and the adjusting buckle is provided with a retaining spring; the bristles are wool strips strung together by a plurality of elastic wires, one end of which is connected to the connecting buckle, and the other end is connected to the top of the brush rod.

The adjusting buckle and the connecting buckle are integrally formed or fixedly connected;

The top of the brush rod is also provided with a second connecting buckle, and the elastic wire is connected to the second connecting buckle;

The second connecting buckle is provided with a hanging hole, and the top is provided with a live hook, which can be hooked on the hanging hole.

The test tube cleaning device provided by the utility model has the characteristics of simple structure, material saving and easy operation. There are strong options for cleaning test tube brushes. The utility model can utilize a test tube brush device to complete the cleaning process of different test tubes and different parts of the test tubes, thereby simplifying the experiment preparation time.

detailed description

The utility model is described in detail below in conjunction with the accompanying drawings: a multifunctional test tube brush as shown in Fig. The bristles 4 formed by root hair strips 8 also have adjustment buckles 2 and connecting buckles 3. The brush rod 5 is provided with a concave ring 7, and the adjusting buckle 2 is provided with a clip spring 6, and the adjusting button 2 is pushed hard, and the adjusting button 2 moves on the brush rod 5, and the clip spring 6 is squeezed by the brush rod 5 so that the clip spring The protruding point of 6 is retracted, and when the protruding point of jump ring 6 moves to the concave ring 7, the adjusting buckle 2 can be stuck on the fixed position, and the adjusting buckle 2 can be moved to the next concave ring 7 by force again. The brush rod 5 can be uniformly provided with a concave ring 7 as a whole, or a concave ring 7 can be provided on a section. Described adjusting buckle 2 is provided with connecting buckle 3, and one end of wool top 8 is installed on connecting buckle 3, and the other end is connected on the top of brush bar 5; The adjustment buckle 2 is integrally formed.

Push the adjustment buckle 2 downwards, and the hair strip 8 is bent, so that the diameter of the bristles 4 becomes larger. Through such adjustment, the test tube brush can adapt to utensils of different sizes.

As an improvement of the present utility model, a connecting buckle can also be provided at the top of the brush rod 5, which is a second connecting buckle 9, and the wool strip 8 is fixed on the second connecting buckle 9. In this way, it can be conveniently replaced when a single wool sliver is lost.

Further, the connection mode between the wool top 8 and the second connecting buckle 9 can be a flexible connection, as shown in Figure 4 and Figure 5, the second connecting buckle 9 is provided with a hanging hole 10, and the wool top 8 is provided with a live hook 11 , during overall use, the live hook 11 is hooked on the hanging hole 10, and the live hook 11 is easily taken off when the top 8 is used alone. With such a structure, the wool strip can be taken off and used alone when the tiny test tube needs to be cleaned. The connection of the same connecting button 3 and wool top 8 also can be this structure.

The test tube brush described in the utility model can not only be used for the cleaning of laboratory equipment, but also can be used for cleaning water cups, teapots and thinner barrel-shaped articles in daily life.

The utility model has a flexible structure, has multiple functions, is suitable for cleaning various shapes, small and large utensils, has a simple structure, saves materials, and is easy to operate. The cleaning utensils are highly selective. The utility model can utilize a test tube brush device to complete the cleaning process of different test tubes and different parts of the test tubes, thereby simplifying the experiment preparation time.
