Description

Self-closing press centrifuge turntable

technical field

The invention relates to a self-closing press centrifuge turntable.

Background technique

A centrifuge is a machine that uses centrifugal force to accelerate the separation of different materials that need to be separated. Centrifuges are widely used in chemical industry, petroleum, food, pharmaceutical, mineral processing, coal, water treatment and shipbuilding and other departments.

The best centrifugal effect of the centrifuge is that the test tube can be placed horizontally for centrifugation, but it is very difficult to disassemble the centrifuge with this horizontal structure. development needs.

Contents of the invention

The purpose of the present invention is to place the test tube obliquely before using the centrifuge. During the use process, the test tube is forced to be placed horizontally for centrifugation due to the centrifugal effect. When opening, the self-closing pressing centrifuge turntable of the centrifuge can be opened by directly pressing the pressing column .

In order to achieve the above object, the technical scheme adopted in the present invention is:

A self-closing pressing centrifuge turntable, the centrifuge turntable is composed of three parts: a turntable main body, a linkage mechanism and a pressing column. Connection, one end has a left connection point connected with the test tube groove, and the other end has a right connection point connected with the pressing column.

Further, the test tube groove has a cavity for the test tube, and the angle between the axis of the cavity and the horizontal plane is 40-50°.

Further, the pressing column is provided with a slide rail for the movement of the right connection point.

Further, the linkage rod connecting the middle end, the left connection point and the right connection point of the linkage mechanism is made of metal material.

During normal use, the cavities on the test tube slots of the centrifuge form an angle of 40~50° with the horizontal plane. This angle can facilitate the direct insertion of test tubes into the test tube slots without being hindered.

When the centrifuge is started to rotate the main body of the turntable, its own centrifugal force will cause the test tube slot to have an outward force, so that the test tube slot drives the linkage mechanism connected to it, and the left connection point rotates, thereby driving the linkage mechanism with the centrifuge. The right connection point of the connection, the right connection point will drive the pressing column to move upward, and the upwardly moving pressing column can be blocked on the test tube opening of the test tube to prevent the cover of the test tube opening from falling off.

When the work is finished, stop the rotating centrifuge, press on the pressing column, and the right connecting point on the pressing column moves down, driving the left connecting point, forcing the test tube groove to open the centrifuge at an inclined angle, so as to facilitate taking the test tube.

After adopting above-mentioned structure, beneficial effect of the present invention is:

1. The structure is reasonable, using the centrifugal force generated by the centrifuge and relying on the linkage mechanism to move the test tube slot down and the pressing column to rise. After use, the test tube slot can be opened by pressing the pressing column to facilitate access to the test tube installed on it. The structure is ingenious Reasonable;

2. The implementation effect is good. The centrifugal force generated by the rotation of the centrifuge will directly force the test tube tank to move, and the rising pressing column can prevent the test solution from flowing out at the opening of the installed test tube. In addition to achieving a good centrifugal effect, it can also Seal and protect the test tube mouth;

3. The operation is convenient. According to the principle of ordinary centrifuge, just install the test tube and start the centrifuge. After the centrifugation operation is completed, press the pressing column to raise the test tube slot, which is easy to take the test tube and easy to operate.

detailed description

The present invention will be further described below in conjunction with the accompanying drawings.

As shown in FIG. 1 , a self-closing pressing centrifuge turntable is composed of three parts: a turntable main body 1 , a linkage mechanism and a pressing column 2 .

The turntable body 1 is provided with a movable test tube groove, the middle end 6 of the linkage mechanism is connected with the turntable body 1, one end has a left connection point 5 connected with the test tube groove, and the other end has a right connection point 7 connected with the pressing column 2. There is a cavity 3 for the test tube on the test tube slot, and the angle between the axis of the cavity 3 and the horizontal plane is 40-50°. The pressing column 2 is provided with a slide rail 8 for the movement of the right connecting point 7 . The linkage rod 4 connecting the middle end 6, the left connection point 5 and the right connection point 7 of the linkage mechanism adopts a metal material.

As shown in Figure 1, during normal use, the cavity 3 on the test tube slot of the centrifuge is at an angle of 40 to 50° to the horizontal plane, and this angle can facilitate the direct insertion of the test tube into the test tube slot without being hindered. And the inclined angle can save more space for accommodating test tubes.

When the centrifuge is started, the turntable main body 1 rotates, and its own centrifugal force will cause the test tube slot to have an outward force, and the test tube slot is limited by the left connection point 5 of the linkage mechanism, and can only rotate through the left connection point 5 , while the middle end 6 only plays the role of rotation, and then drives the right connection point 7 connected with the linkage mechanism. The right connection point 7 will drive the pressing column 2 to move upward, and the right connecting point 7 will pass through the slide rail 8 to the pressing column. 2 moves inside, slide rail 8 provides necessary movement space, and the pressing post 2 that moves upward can stop on the test tube opening of test tube, avoids the cover of test tube opening from coming off.

As shown in Figure 2, when the work is completed, stop the centrifuge, press on the pressing column 2, and the right connecting point 7 on the pressing column 2 moves down, driving the left connecting point 5, forcing the test tube groove to be inclined Angled open centrifuge for easy access to tubes.

The linkage rod 4 made of metal material can reduce the damage caused by the stress intensity, and can effectively increase the service life of the centrifuge.
