Description

[Detailed Description of the Invention] This utility model relates to a flexible funnel stand that can adjust the diameter of the funnel hole.

Usually, a rotary separation funnel has a structure shown in FIG. 1, and can be roughly divided into three types.

That is, small size for 100ral, 200~3001rL
A medium size for L, and a large size for 500 to 10100O.

The number of funnel holes is 6 to 1, and the diameter of each funnel hole is 4.
The standard size is 5.6.0.8.5 cm.

However, in actual laboratories, there are many occasions when separating funnels with different capacities are used at the same time, and each time a plurality of rotary separating funnel stands are required, which takes up a lot of space.

In addition, if we tried to make do with a single rotary separation funnel in order to alleviate this inconvenience, we would have to carry out the experiment with the separation funnel having an unsuitable capacity in an unstable manner. This causes problems in terms of experimental accuracy and safety.

The purpose of this invention is to eliminate such conventional drawbacks, expand the applicable capacity range of the separating funnel in one rotary separating funnel stand, and use it to adapt to changes in the capacity of the separating funnel. The objective is to provide a flexible funnel table that can be used to

In the present invention, a rotatable funnel support plate that can be fixed at any height is attached to a support that is erected on a base plate, and multiple holes are drilled in the funnel support plate. In a separating funnel stand having a structure in which a part from the outer circumference of the funnel support plate is cut out, each of the plurality of holes has a cutout part corresponding to the width of the cutout part of the funnel support plate, and is removable. This is a flexible funnel stand that features a structure that incorporates multiple inner frames.

The present invention will be explained below based on the drawings.

FIG. 1 is a diagram showing a conventional separating funnel stand.

A funnel support plate 11 having a funnel hole 12 is attached to a support 13 erected on a base plate 14.

Further, a portion from each funnel hole 12 to the outer periphery of the funnel support plate 11 is cut away.

In these separation funnel stands, the funnel holes 12 all have the same size and shape, or even if they have several different sizes, it is impossible to install the desired number of funnels with various sizes. There was.

Next, FIG. 2 shows an embodiment of the separating funnel stand of the present invention.

In FIG. 2, the funnel hole 12 is a circle with a size suitable for a large-capacity separating funnel, and has a structure in which a portion of the funnel support plate 11 up to the outer periphery is cut away.

A ring-shaped inner frame 21, 22 having a cutout portion corresponding to the width of the cutout portion is inserted into the funnel hole from above the funnel support plate 11.

FIG. 3 is an enlarged perspective view of this funnel hole portion in more detail.

The inner frame 21 has a forest-like structure in which the upper diameter is wider than the lower diameter with respect to the funnel support plate 11, and the inner frame 22 has a forest-like structure as well.

With this structure, as shown in the cross-sectional views in Figures 4a and 4b, the inner diameters <31 and 32 can be placed on the funnel support plate 11 in sequence from above, and the operation is extremely simple. It is.

FIG. 5 shows a sectional view of another embodiment.

With respect to the funnel support plate 11, the inner frame 41 slides a sloped surface 44 in the form of a forest onto a surface 45 by a surface 46.

Similarly, the inner frame 42 has a structure in which a forest-like slope surface is slid along the middle of the inner frame 41.

Here, the surface 46 that intertwines the inclined surface 44 and the slid inclined surface 45 does not necessarily have to be a horizontal surface, and may be a surface 46 that does not interfere with assembling the inner frame 41 into the funnel support plate 11 from above. It is also possible to fix the inner frame by making it moderately uneven.

The same applies to the inner frame 42.

Since the present invention allows individual funnel holes to be adjusted, it is possible to support separating funnels of various sizes as long as there are number of funnel holes, regardless of the capacity of the supporting separating funnel.

Therefore, it can be seen that compared to conventional products, it takes up less space, is more economical, and can contribute to the safety, accuracy, and speed of experiments.
