Description

Portable Test Tube Rack

technical field

The utility model belongs to a chemical laboratory instrument and equipment, in particular to a portable test tube rack.

Background technique

In chemistry teaching, chemical experiment is an indispensable content. Some chemical experiments need to be carried out in the classroom through the teacher's demonstration. Test tubes are often used in experimental vessels. Cleaned test tubes are stored on test tube racks. The frames are all rectangular in outline and are divided into bottom, middle and upper layers. When test tubes are used in classroom experiments, the test tube racks and test tubes are usually transported to the classroom manually. The test tube racks currently used are inconvenient to carry manually, and the open test tube racks are prone to dust during the handling process, which is not conducive to maintenance. Cleaning of test tubes.

Utility model content

The purpose of the utility model is to overcome the deficiencies in the prior art and provide a portable test tube rack which is easy to carry and use, and is beneficial to keep the test tubes clean.

In order to achieve the above object, the utility model adopts the following technical solutions: the portable test tube rack of the utility model includes a test tube rack, the outer contour of the test tube rack is cylindrical, and the center of the test tube rack is rotatably arranged on a vertical central axis, and the center The shaft is fixed vertically on the base and is located above the test tube rack. A top plate is set on the central axis, and the top plate is parallel to the base. The top plate is opposite to the outer edge of the base. It is fixed on the inner side of the upper and lower circular slideways of the top plate and the base, and an arc-shaped left door panel and an arc-shaped right door panel are slidably embedded in the upper and lower circular slideways of the top plate and the base. Features carry handles.

After adopting above-mentioned technical scheme, the beneficial effect of the utility model is:

1. Easy to carry and use. Because the outer profile of the test tube rack of the utility model is cylindrical, and is rotatably arranged on the vertical central axis between the top plate and the base, the top plate is provided with a handle. Therefore, the test tubes can be easily carried to the classroom by hand, and when the test tubes are needed for the experimental demonstration, the test tubes can be taken out one by one conveniently by rotating the test tube holder.

2. It is beneficial to keep the test tube clean. The utility model embeds an arc-shaped left door panel and an arc-shaped right door panel symmetrically and slidably in the upper and lower circular slideways of the top plate and the base, so that during the carrying process, the arc-shaped left door panel can be closed by relative rotation. The door panel and the arc-shaped right door panel close the test tube rack to prevent environmental dust from falling into the test tube and polluting it, which will affect the experimental demonstration.

Detailed ways

Below in conjunction with accompanying drawing and specific embodiment the utility model is described in further detail:

As shown in Fig. 1 and Fig. 2, the structure diagram of the specific embodiment of the portable test tube rack of the present invention is provided, including the test tube rack 1, the outer contour of the test tube rack 1 is cylindrical, and the center of the test tube rack 1 is rotatably arranged on On the vertical central axis 6, the central axis 6 is vertically fixed on the base 2 and is located above the test tube rack 1. A top plate 5 is arranged on the central axis 6, and the top plate 5 is parallel to the base 2. The top plate 5 is outside the base 2. The upper and lower edges are oppositely provided with circular slideways, and the semicircular arc-shaped shell plate 3 is vertically fixed on the inner side of the upper and lower circular slideways between the top plate 5 and the base 2, and inside the upper and lower circular slideways between the top plate 5 and the base 2 Left and right symmetrical and slidably embedded circular arc-shaped left door panels 4 and circular arc-shaped right door panels 8 can be closed by relative rotation. Be provided with handle 7, can adopt portable mode to carry test tube.

When using the portable test tube rack, the test tubes washed first are placed on the cylindrical test tube rack 1, and the arc-shaped left door 4 and the arc-shaped right door 8 can be closed by relative rotation to close the test tube rack 1. When carrying out on-site chemical experiment demonstrations in the classroom, the test tube can be carried to the classroom in a portable manner, which is very convenient to carry. During the experiment, the arc-shaped left door panel 4 and the arc-shaped right door panel 8 are opened by reverse rotation, and the test tube rack 1 is placed on the Half of the test tubes are exposed and can be easily taken out for use. During the experiment, the test tubes can also be taken out one by one conveniently by rotating the test tube rack. The utility model effectively solves the problems of test tube carrying and closed storage, and has the characteristics of simple structure and convenient use and operation.

The utility model is suitable for carrying test tubes during experiment demonstration in chemistry classrooms.
