Description

Technical Field

[0001] The present application relates to the technical field of water bath thermostatic oscillators, and in particular to a vessel mounting rack for a water bath thermostatic oscillator and a water bath thermostatic oscillator. Background Art

[0002] The water bath constant temperature oscillator is a biochemical instrument that combines a temperature-controllable constant temperature water bath and an oscillator. It is widely used in scientific research departments such as universities, medical, petrochemical, health and epidemic prevention, and environmental monitoring for oscillating cultivation of various liquid and solid compounds such as biology, biochemistry, cells, and bacteria.

[0003] The existing water bath constant temperature oscillator mainly includes an oscillator body, an actuator, a temperature control device, a vessel mounting frame and related auxiliary accessories. In specific applications, the experimental vessel is fixed on the vessel mounting frame, which is installed in the oscillator body and oscillates through the actuator; when maintaining a constant temperature, water is injected into the oscillator body and adjusted to the target temperature through the temperature control device, thereby achieving the purpose of maintaining the constant temperature of the vessel.

[0004] The actual application of the water bath thermostatic oscillator will cause the fluid in the oscillator body to vibrate, and the fluid vibration will produce fluid fluctuations. When the oscillation frequency and oscillation amplitude are too large, the fluid will splash out of the oscillator body, and in some cases may even enter the experimental vessel and contaminate the internal experimental samples. Secondly, the fluid fluctuations caused by fluid vibration will complicate the vibration of the water bath thermostatic oscillator, and the resulting flow-induced vibration will increase the difficulty of oscillator feedback control. When the vibration is too large, it may even affect the safety of the oscillator, affecting the further improvement of high-frequency and large-amplitude water bath thermostatic oscillation technology. Summary of the invention

[0011] By adopting the above technical solution, when in use, the vessel mounting frame is placed in the water bath thermostatic oscillator, and the mounting base plate is fixed to the water bath thermostatic oscillator.

At this time, the fluid in the water bath thermostatic oscillator is approximately a mass entity in terms of dynamics. When the water bath thermostatic oscillator is working, the internal fluid exhibits overall translation, and the original fluid movement is greatly reduced or even disappears, thereby achieving the purpose of reducing the fluid splashing and instrument vibration complication caused by fluid fluctuations during the high-frequency and large-value operation of the water bath thermostatic oscillator.

[0012] Furthermore, a limiting partition is arranged between the installation base plate and the adjustment pressure plate, and the limiting partition comprises a plate frame, and a limiting member for limiting the experimental vessel is arranged on the plate frame.

[0013] By adopting the above technical solution, the limiting member of the limiting partition plays the effect of buffering the experimental vessel and limiting its position.

[0014] Furthermore, the limiting member is configured as an elastic rope, and the elastic rope is crisscrossedly arranged on the plate frame to form a plurality of positioning openings for the experimental vessels to pass through.
