Abstract

The invention relates to a horizontal reciprocating swinging device, which is mainly applied to uniform mixing, or cell culture, and the like, of a plurality of liquid compounds for bioluminescence analysis, biochemiluminescence analysis, chemiluminescence analysis, enzyme linked immunosorbent assay, radioimmunoassay, and the like. The swinging device comprises a driving motor, an eccentric wheel structure, a revolving crank structure, a linear swinging sample plate, and a base support structure equipped with a guiding shaft, wherein the housing of the driving motor is in screw connection with the base support; the linear swinging sample plate is in screw connection with a linear bearing and horizontally swings along a linear guide in a single direction. According to the swinging device, rotational motion of a motor shaft is transferred to another rotation shaft fixed to the eccentric wheel structure via a synchronous belt, and the rotation shaft is connected to the linear swinging sample plate via the revolving crank structure to convert the rotational motion of the motor into linear horizontal reciprocating swinging motion. The swinging device is flexible in movement and convenient to use; a hinged shaft of a swing arm is supported by a pair of bearings; and the swinging device has small friction, high rotating accuracy, and long service life. The swinging device is simple and compact in structure, small in size, and high in working reliability and stability; the cost is relatively low; and the use cost for device preparation and a user is reduced.

Description

technical field [0001] The invention relates to a swinging mechanism of a shaking table, in particular to a swinging mechanism of a workbench suitable for special equipment for liquid oscillation and mixing. It belongs to the technical field of biochemical instruments. Background technique [0002] In the research of biology, medicine, food, agricultural science, etc., it is necessary to mix various liquid and solid compounds or to incubate cell cultures. This process needs to be carried out on a sample table with a certain swing frequency, which can improve the mixing degree, increase the reaction speed, and shorten the reaction time. The common sample plate surface reciprocating swing device is driven by the motor through the crank connecting rod to swing the sample plate. Due to the different mechanism structure, its reliability, control accuracy, vibration and noise are quite different, which often leads to unstable quality of supporting equipment. [0003] The design ...
