DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a shaker capable of tilting and oscillating in a vertical wave type, and more particularly to a shaker capable of adjusting the size of a wave type to a fixed or large size. The present invention relates to a shaker which can be effectively used for analysis of DNA extraction, hybridization, gel staining / decolorization, and the like.

[0002]

2. Description of the Related Art Conventionally, a shaker which oscillates in a wave form is shown in FIG.
As shown in the figure, a motor in which a rotating shaft 22 faces upward in a box 21
23 is provided, a bent portion 24 is provided on the upper portion of the rotating shaft 22, a shaking table 26 is attached to the upper end of the bent portion 24 via a bearing 25, and the shaking table 26 is not continuously rotated with the rotating shaft 22. Therefore, it is configured to be supported by a vertically extending and contracting support member 27.

However, the above-mentioned shaker requires a dedicated motor 23 having a bent portion 24, which is expensive, and the structure of the support member 27 is complicated, which causes a failure. There was a problem that the amplitude of the shaking table could not be adjusted at all.

[0003]

According to the present invention, a horizontal rotator 2 is provided in a box 1 having an opening on the upper surface, and a play hole 3 is provided at an eccentric point on the upper surface of the horizontal rotator 2 so that the upper end is formed. The rotating shaft 4 protruding above the opening is loosely fitted and inserted without rotation.
A bearing 5 that can be fixed or moved up and down to concentrate the rotation trajectory on the center of the horizontal rotating body 2 is inserted in the middle of the shaft, and a shaking table 6 is supported at the upper end of the turning shaft 4. A configuration in which a tongue 6 is tilted and oscillated in a wave form based on the bearing 5, and two or more play holes 3 on the upper surface of the horizontal rotating body 2 are arranged side by side from the center toward the side circumference. It is intended to solve such a problem.

[0004]

When the switch is turned on to rotate the horizontal rotator, the rotary shaft inserted into the play hole at the eccentric position of the horizontal rotator.
Is eccentrically swiveled, and a swivel axis 4 is set on the center of the horizontal rotating body 2.
The upper half of the pivot 4 pivots symmetrically with the lower half based on the bearing 5 fitted externally in the middle of the shaft, whereby the shaking table 6 attached to the upper end of the pivot 4 stops as if the top of the rotary stops and falls. In this state, the wave swings in the state immediately before the operation. When the bearing 5 is adjusted to move up or down, the inclination angle of the turning shaft changes depending on the amount of movement of the distance between the play hole 3 and the bearing 5, so that the angular amplitude of the shaking table 6 can be adjusted to be large or small. . In addition, two or more play holes 3 are provided on the upper surface of the horizontal rotating body 2, and the play holes 3 which are far from the center are selected and the revolving shaft 4 is inserted. Similarly, the angle amplitude can be changed.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment will be described below with reference to the drawings.

FIGS. 1 and 2 show a first embodiment.
The opening in the box 1 having a circular opening 1a in the center of the upper surface
The motor 7 is provided at a position 1a below, and the center of the bottom of the cylindrical horizontal rotating body 2 is attached to the upward shaft 7a of the motor 7. A bottomed play hole 3 is provided at an eccentric point on the upper surface of the horizontal rotating body 2, and a lower end of a round bar-shaped turning shaft 4 having a smaller diameter than the playing hole 3 is loosely inserted and set up, and an intermediate portion of the turning shaft 4 is provided. Are supported by an outer fitting of a two-tube bearing 5 that slides on the center of the horizontal rotating body 2. The bearing 5 is a fixing member 5a extending to one side.
And is fixedly fastened to a mounting plate 8 provided in the box 1. The upper end of the revolving shaft 4 projects above the opening 1a, and supports the center of a shaking table 6 formed in a flat and rectangular shape by fitting a support member 4a to the projecting portion. Reference numeral 9 denotes a stopper mechanism for rotating the rotating shaft 4 in a non-rotating manner. As shown in FIGS. 2 and 3, the stopper mechanism 9 is fitted to the intermediate position of the rotating shaft 4 and attached to the extended protruding rod 9a and attached to the box 1. And a frame member 9b that allows the stopper rod 9a to swing up and down and prevents swinging in the horizontal direction. Although not shown, a 1.5 ml microtube test tube, a container holder dedicated to a centrifuge tube, and the like, which are often used in molecular biology research, are interchangeably mounted on the shaking table 6.

When the horizontal rotating body 2 is rotated by the motor 7 with the switch 10 turned on, the eccentric rotation of the lower end of the rotating shaft 4 causes the shaking table 6 to pivot on the bearing 5 as shown in FIG. In this case, the tilt swing is performed.

FIGS. 6 (a) and 6 (b) are cross-sectional views of a main part of a second embodiment of the present invention.
A bearing 5 is provided at the lower end of the cylindrical body 11 so as to be fitted to the revolving shaft 4, and the cylindrical body 11 is rotated up and down to move the position of the bearing 5 upward. Alternatively, the tilt angle of the turning shaft 4 can be adjusted by adjusting the inclination angle of the turning shaft 4 by lowering the distance to the horizontal rotating body 2 so that the angular amplitude of the shaking table 6 can be adjusted.

FIG. 7 shows a third embodiment in which four play holes 3 are juxtaposed on the horizontal rotating body 2 from the center C to the side circumference. By selecting and inserting one of the play holes 3 with the turning shaft 4 far from the center, the amount of eccentricity can be adjusted and the angular amplitude of the shaking table 6 can be adjusted.

[0010]

According to the present invention having the above-described structure, it is possible to provide an inexpensive wave-oscillation-type shaker having a simple structure, easy operation, and less failures.

[0011] Further, there is an effect that the amplitude of the shaking table can be adjusted by adjusting the vertical movement of the bearing that supports the swing shaft, or by selecting and inserting a play hole that is far from the center of the swing shaft.

[0012] The above results show that the unique shaking of a wave type shaker can be widely and effectively used by installing a container holder dedicated to a 1.5 ml microtube test tube and a centrifuge tube, which are often used in molecular biology research. This has the effect of enabling
