JPH0523618A - Centrifugal separator - Google Patents

Abstract

PURPOSE:To improve the operability of the centrifugal separator in such a manner that an operator can see a display part at an optimum angle regardless of his height even if the operator stands in any position relative to the centrifugal separator. CONSTITUTION:The display part is constituted of a display panel 4, a central pole 8 which moves this panel, and a base joint, angle joint and spring for stopping the panel in an arbitrary position in a vertical direction.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a centrifuge which rotates at a high speed and separates a sample by centrifugal force, and its operability is improved.

[0002]

2. Description of the Related Art In a conventional centrifuge, the setting display of the number of revolutions and the operating time is displayed in one panel, and the panel is fixed to the main body. In addition, the operation status and setting conditions are CR
There are some that use a monitor such as the T, but it has a structure that is integrated with the operation panel.

[0003]

In the conventional centrifuge, since the display portion and the operation portion are fixed to the centrifuge body, when the rotor is set in the centrifuge, it stands at a position deviated from the front of the panel. The operator must move to the front of the panel when setting or viewing the operating status.Because of the difference in height, the operator can move away from the angle at which the display panel is in front of the display panel, and light from indoor fluorescent lamps etc. There was a problem that it became difficult to see because it was reflected.

An object of the present invention is to enable one-handed operation so that the display panel can be viewed at an optimum angle from any angle within the reach of the operation panel.

[0005]

The above object is achieved if the display panel is not fixed to the centrifuge body but is movable vertically and horizontally. In addition, for the rotation of the vertical angle on the back surface of the display panel, a member such as a spring that constantly generates a frictional force of a certain level or more is arranged between the rotary shaft and the movable part, and it is always stopped at an arbitrary angle so that one-handed operation is possible. The purpose is achieved.

[0006]

With the above structure, when the operator is next to the operation panel, the operator can move the display panel left and right to bring the operator to the front of himself. In addition, even a tall person or a short person can move the display panel up and down so that the display panel can be easily viewed. Also, when the light of the fluorescent lamp in the room is reflected, the light can be viewed at a position where it is not reflected by moving the angle vertically or horizontally. Members such as springs on the back of the display panel are
Generates a certain amount of frictional force between the stationary part and the rotating part,
Moreover, even if the contact portion is worn, the frictional force is maintained.

EXAMPLES Examples of the present invention are shown in FIGS. A table 2 is provided on the upper part of the centrifuge body 1, an operation panel 3 is fixed to a part of the table 2, and a display panel 4 connected to a pole 8 is provided on an upper part of the table 2, which rotates in the left-right direction around the pole 8.
As shown in FIGS. 2 and 3, the connecting portion between the pole 8 and the display panel 4 has an angle joint 9 in a side hole of a base joint 11 fixed to a stay 10 that supports a display 16 for displaying and a display cover 15. The shaft portion is inserted and the stopper 12 is fixed to the shaft end so that the angle joint 9 does not come off even if it can rotate. The hole of the angle joint 9 is a pole 8 fixed to the centrifuge body 1.
The shaft of the pole 8 can be rotated about the shaft of the pole 8.

A pin 13 stands on a portion of the stopper 12, and the pin 13 and the stay 10 are connected by a spring 14 that exerts a tensile force, and the shaft 9 of the angle joint and the hole of the base joint 11 are connected. Generates a constant frictional force. By this frictional force, the display panel 4 can be fixed at an arbitrary angle even if it is moved in the vertical direction. If the pulling force of the spring 14 is within the range shown in FIG. 4, the display panel 4 can be stopped. The data in FIG. 4 is for when the weight of the display unit 4 is about 1 kg, the vertical axis indicates the tensile force of the spring 14, and the horizontal axis indicates the angle θ of the display panel 4 as shown in FIG.

The pole 8 is hollow, and a cable for supplying power and signals to the display 16 is passed through the pole 8. As a result, the display panel 4 and the centrifuge body 1 can be connected only by the pole 8.

[0010]

According to the present invention, since the display unit 8 is vertically and horizontally movable, the display panel can be moved and viewed at an optimum angle regardless of the standing position and height of the operator. be able to. Further, by providing a spring that constantly generates a frictional force above a certain level between the movable part and the fixed part, the display part can be moved with only one hand and can be stopped at an arbitrary angle.
