Detailed Description

The following detailed description will be made in conjunction with embodiments of the present invention with reference to the accompanying drawings.

A shaking device for a volumetric flask comprises a supporting component, a shaking component and a rotating component;

the supporting assembly comprises a supporting plate 1, a pair of brackets 2 and a fixing plate 6, and as shown in fig. 4, the pair of brackets 2 and the fixing plate 6 are arranged on the top surface of the supporting plate 1;

the shaking assembly comprises a first motor 7, a rocker arm 9 and a hinged connecting block 3;

as shown in fig. 1 and 3, the first motor 7 is fixed on the fixing plate 6, the hinge connection blocks 3 are hinged in the paired brackets 2, an output shaft of the first motor 7 is connected with a turntable 8, a protrusion is arranged on the outer side of the turntable 8, and the protrusion is connected with a connection hole at one end of the rocker arm 9 through a bearing; the connecting hole at the other end of the rocker arm 9 is connected to the hinged connecting block 3 through a bearing;

as shown in fig. 7, the rotating assembly includes a second motor 4 and a capacity bottle holder 5, the second motor 4 is fixed in the hinged connection block 3, and an output shaft of the second motor 4 extends upward and is connected to the bottom of the capacity bottle holder 5, as shown in fig. 2, a gap exists between the bottom of the capacity bottle holder 5 and the hinged connection block 3, which facilitates the rotation of the capacity bottle holder 5.

Further, 5 top surface openings on the capacity bottle support are provided with rubber snap rings, and the rubber snap rings have elasticity to facilitate the feeding and discharging of the capacity bottle, and can prevent the capacity bottle from being separated in vibration.

The using method comprises the following steps:

as shown in fig. 7-9, the volumetric flask after being shaken up and filled with liquid is placed in the volumetric flask holder 5, the cap is closed, the first motor 7 and the second motor 4 are opened, the output shaft of the first motor 7 drives the rotary table 8 to rotate, the rotary table 8 drives the rocker arm 9 to swing left and right, the rocker arm 9 pulls the hinged connecting block 3 to swing left and right, the hinged connecting block 3 swings left and right to drive the second motor 4 to swing left and right, and the second motor 4 drives the volumetric flask holder 5 to swing left and right; meanwhile, the output shaft of the second motor 4 rotates to drive the capacity bottle support 5 to rotate in the horizontal direction; the volumetric flask in the volumetric flask holder 5 swings left and right and rotates in the horizontal direction (i.e. in the direction parallel to the bottom surface of the volumetric flask holder 5).
