The present invention will become more fully understood from the detailed description given hereinbelow and the accompanying drawings which are given by way of illustration only, and thus are not limitative of the present invention, and wherein:
As shown in
The first driving motor 10 is fixedly mounted on a base plane 1 of an instrument (not shown) and controlled to output a rotary driving force.
The first transmission rod set 20 comprises a transmission rod 21 and two gearwheels 22. The transmission rod 21 is rotatably supported on the base plane 1 and connected with its one end to the first driving motor 10. Therefore, the transmission rod 21 is rotatable on its own axis by the first driving motor 10. The two gearwheels 22 are respectively affixed to the transmission rod 21 near the two distal ends of the transmission rod 21 for synchronous rotation with the transmission rod 21.
The first synchronous transmission members 30 are toothed transmission belts respectively meshed with the gearwheels 22 of the first transmission rod set 20 for synchronous rotation with the gearwheels 22.
The first tension-adjusting members 40 are respectively mounted on the base plane 1 and respectively spaced apart from the gearwheels 22 at a distance and respectively coupled to the first synchronous transmission members 30 to control the tension of the respective first synchronous transmission member 30. By means of adjusting the positions of the first tension-adjusting members 40 relative to the gearwheels 22, the tension of the respective first synchronous transmission member 30 is relatively adjusted to ensure synchronous rotation of the gearwheels 22 with the first synchronous transmission members 30.
The second driving motor 50 is fixedly mounted on the base plane 1 and controlled to output a rotary driving force.
The second transmission rod set 60 comprises a transmission rod 61 and two gearwheels 62. The transmission rod 61 is rotatably supported on the base plane 1 and connected with its one end to the second driving motor 50. Therefore, the transmission rod 61 is rotatable on its own axis by the second driving motor 50. Further, the extending direction of the transmission rod 61 of the second transmission rod set 60 is perpendicular to the extending direction of the transmission rod 21 of the first transmission rod set 20. The two gearwheels 62 are respectively affixed to the transmission rod 61 near the two distal ends of the transmission rod 61 for synchronous rotation with the transmission rod 61.
The second synchronous transmission members 70 are toothed transmission belts respectively meshed with the gearwheels 62 of the second transmission rod set 60 for synchronous rotation with the gearwheels 62.
The second tension-adjusting members 80 are respectively mounted on the base plane 1 and respectively spaced apart from the gearwheels 62 at a distance and respectively coupled to the second synchronous transmission members 70 to control the tension of the respective second synchronous transmission member 70. By means of adjusting the position of the second tension-adjusting members 80 relative to the gearwheel 62, the tension of the respective second synchronous transmission members 70 is relatively adjusted to ensure synchronous rotation of the gearwheels 62 with the second synchronous transmission members 70.
The moveable platform 90 comprises a platform base 91, a first connecting rod 92, and a second connecting rod 93. The first connecting rod 92 is slidably inserted through the platform base 91, having two distal ends respectively extending out of two first opposite sides of the platform base 91 and respectively coupled to the first synchronous transmission members 30. Therefore, rotating the first synchronous transmission members 30 moves the first connecting rod 92 and the platform base 91 in one direction, i.e., X-axis direction. The second connecting rod 93 is slidably inserted through the platform base 91, having two distal ends respectively extending out of two second opposite sides of the platform base 91 and respectively coupled to the second synchronous transmission members 70. Therefore, rotating the second synchronous transmission members 70 moves the second connecting rod 93 and the platform base 91 in one direction, i.e., Y-axis direction.
After understanding of the component parts of the present invention and their relative relationship, the operation of the shaking mixer 100 is described hereinafter.

Therefore, by means of controlling the operation of the first driving motor 10 and the second driving motor 50, the platform base 91 can be oscillated in different directions to produce different shaking effects for mixing reagents. Therefore, when a mixing container carrying different reagents is placed on the platform base 91, the platform base 91 can be oscillated in different directions, causing the reagents in the mixing container to be well mixed.
Further, the invention uses the first synchronous transmission members 30 the second synchronous transmission members 70 to move the platform 90 in two different directions, i.e., the first synchronous transmission members 30 are respectively connected to the platform 90 at two opposite sides and the second synchronous transmission members 70 are respectively connected to the platform 90 at the other two opposite sides so that the platform 90 has two opposite sides simultaneously moved in one direction, preventing biasing or inaccurate displacement of the platform 90 due to drawback of driving the platform from one single side.
The invention being thus described, it will be obvious that the same may be varied in many ways. Such variations are not to be regarded as a departure from the spirit and scope of the invention, and all such modifications as would be obvious to one skilled in the art are intended to be included within the scope of the following claims.
