Guide rail type circumferential oscillating mechanism stepwise adjustable in amplitude

Abstract

The invention discloses a guide rail type circumferential oscillating mechanism stepwise adjustable in amplitude. The guide rail type circumferential oscillating mechanism comprises a rocking plate, guide rail sliders, extending square-shaped guide rails, a bearing holder, a lower frame and an eccentric adjusting mechanism; the lower end of the eccentric adjusting mechanism is mounted on the lower frame by use of a bearing and the bearing holder, while the upper end of the eccentric adjusting mechanism is connected with the rocking plate; the extending square-shaped guide rails are divided into upper and lower two layers; the rocking plate is connected with the upper-layer guide rails of the extending square-shaped guide rails by use of the guide rail sliders; the lower-layer guide rails of the extending square-shaped guide rails are fixed on an upper frame; the guide rail sliders are capable of sliding relatively to the upper-layer guide rails, and the upper-layer guide rails are capable of sliding left and right relatively to the lower-layer guide rails; the rocking plate is capable of circumferentially oscillating on the extending square-shaped guide rails. According to the guide rail type circumferential oscillating mechanism stepwise adjustable in amplitude, the vibration system is high in reliability due to rigid connection; the pin hoe of a disc at a driving shaft end can be matched with different pin holes of a disc at a driven shaft end, and the stepwise adjustment of the vibration amplitude can be realized.

Description

technical field [0001] The invention relates to a guide rail type circular oscillating mechanism with step-adjustable amplitude widely used in medicine, biology, pharmacy, food, environmental protection, inspection and agricultural science experiments and research. Background technique [0002] The circular oscillating mechanism, also known as a shaking table, is a common laboratory equipment and is widely used in bacterial culture, fermentation, biochemical reactions, and enzyme tissue studies that have high requirements for temperature and oscillation frequency. The periodic vibration of the shaking table can not only make the bacteria float up and distribute evenly in the petri dish, but also increase the amount of dissolved oxygen, which is beneficial to the proliferation of bacteria. In applications in the fields of biology and medicine, different training objects have different requirements for the amplitude of the circular oscillation mechanism, so this requires that ...

AI Technical Summary

Problems solved by technology

At present, most of the existing shakers are realized by a crankshaft with a fixed eccentric value, the vibration amplitude is fixed, and the versatility is very low. Although a few shakers can achieve adjustable amplitude, their structure is complicated and the production cost is high.

Moreover, the existing shaking tables all adopt a single-axis support method, and the axial force is too concentrated, which limits the speed of the shaking table
