Description

[Detailed explanation of the idea] The present invention relates to an improvement of a funnel stand.

There is a multi-phase funnel stand in which a circular funnel support plate with a plurality of funnel holes around its periphery is rotatably attached to a column fixed to the base.

By making the support plate rotatable, the funnel holder allows any funnel hung in the hole to be positioned in front of the user as needed, making it easy to use.

However, if the base plate accidentally rotates during use, the funnel hung on the base plate and the flask placed on the base to receive the filtrate may become misaligned, causing an accident such as the funnel falling over. There is.

In addition, since the part on which the funnel is hung is one step, it is impossible to directly receive the filtrate into the separating funnel.

The present invention solves the problems of the above-mentioned funnel stand.

The present invention will be explained based on the embodiment shown in the drawings.
2 is a disk-shaped base, and 2 is a mounting pipe that is erected on the base 1 by screwing its lower end into the upper surface of the center of the base 1, and has a thread formed on its inner circumferential surface.

Reference numeral 3 designates a pillar with a circular cross section that is erected on the base 1 by screwing its lower end into the mounting pipe 2, and 4 is a disc-shaped turntable that is placed on the base 1 so as to be rotatable about the mounting pipe 2. .

An annular groove 5 is formed on the outer and inner edges of the upper surface of the rotary table 4.
5 is formed so that even if a reagent solution or the like spills onto the rotating table 4, it will not flow down from the rotating table 4 to the base 1 or the like.

6 is a circular funnel support plate rotatably attached to the support column 3;
A plurality of funnel supports are formed by providing holes 7 around the circumference of a disc made of transparent acrylic resin or the like, with the outer peripheral end partially open.

To attach the funnel support plate 6 to the support column 3, a pipe with an inner diameter that matches the support column 3 is fixed to the center of the support plate 6 in a penetrating manner, the hole is used as a mounting hole 8, and the support column 3 is inserted into the mounting hole 8. The lower surface is supported by a fixture 9 attached to the support column 3.

The fixture 9 is pipe-shaped and has an inner diameter that matches the support column 3.
A threaded rod 1 with a support 3 inserted into it and penetrated through the peripheral wall
0, the tightening is fixed to the column 3, and the position of the individual fixture 9 can be adjusted by loosening the threaded rod 10.

11 is a through hole provided on the inner peripheral side of the funnel support plate 6; 12 is a rod that is inserted into the through hole 11; a pipe-shaped rod having a thread formed at its lower end and a thread that engages with this screw formed on the inner peripheral surface; It is formed so that it can be attached to and detached from the rotary table 4 via the attachment member 13.

The lower end of the mounting member 13 is screwed into the rotary table 4 and fixed thereto.

Note that the rod 12 can be attached to and removed from the rotary table 4 through a cylindrical body equipped with a spring that can clamp the lower end of the rod 12. The method doesn't matter.

Reference numeral 14 indicates a plurality of protrusions provided on the top surface of the base 1 to ensure smooth rotation of the rotary table 4. Reference numeral 15 indicates a recess provided on the lower surface of the rotary table 4 that fits into the protrusion 14. When the two fit together, rotation is achieved. Although the positioning of the stand 4 is ensured, the configuration thereof is not particularly limited.

In addition, although the case where the support|pillar 2 was installed upright on the base 1 was shown in the Example, it is also possible to install the support|pillar 2 upright on the rotating stand 4 rotatably provided on the base 1.

As shown in the embodiment, if two support plates 6 are attached,
It has the advantage of being able to receive the filtrate directly into the separatory funnel, but
The number of support plates 6 is not limited.

The funnel of the present invention has the above-described configuration, and by rotating the rotary base 4 and the support plate 6, the user can effectively operate all parts of the funnel while remaining positioned on one side of the funnel base. It can be used.

Moreover, when there is no need to rotate the base plate 6 relative to the rotary base 4, such as when performing parallel tests with multiple sets of funnels and receivers set on the funnel base, the base plate 6 By inserting the rod 12 into the through hole 11 and fixing its lower end to the rotary table 4, the support plate 6 can be made unrotatable relative to the rotary table 4. Accidents such as rotating the chisel and knocking over the receiver can be reliably prevented.

When simultaneously receiving filtrate from separate separating funnels into one receiver, the rod 12 is removed and the support plate 6 is moved to the rotating table 4.
If the support plate 6 is rotated and a plurality of separating funnels set thereon are sequentially positioned on the receiver, the work can be carried out extremely smoothly.

Furthermore, when the support plates 6 are provided in two stages, the relative rotation between the two support plates 6 can be disabled or made possible by attaching and detaching the rod 12. In addition to the aforementioned effects that can be achieved in the relationship between the rotary table 4 and the support plate 6, the same effects can also be achieved in the relationship between the two support plates 6.

That is, in the case where separating funnels and the like are set in two stages, upper and lower, on both support plates 6, if there is no need to rotate the upper support plate 6 with respect to the lower support plate 6, attach the rod 12, In some cases, the same effect as in the above case can be achieved by removing the rod 12.

In addition, if the rod 12 is divided at the position between the two support plates 6 and made possible to connect with screws, etc., then when only the upper support plate 6 is to be rotated, the rod 12 is divided and the lower support plate 6 is connected. 6 can be fixed to the rotary table 4, which is convenient.
