Embodiment 1
[0036] Such as Figure 1-2As shown, the present invention provides a technical solution: a stirring device for biochemical experiments, including a stirring tank 1, the inside of the stirring tank 1 near the top is fixedly connected with a limiting support plate 2, and the middle position of the top of the limiting support plate 2 is fixedly connected There is a driver 3, the outer side of the output shaft of the driver 3 is evenly and fixedly connected with a swing rod mechanism 4, and the surface of the inner wall of the stirring tank 1 is evenly and fixedly connected with an air booster mechanism 5;
[0037] The pendulum mechanism 4 includes a stirring communication plate 41, the left side of the stirring communication plate 41 is rotationally connected with the driver 3, the surface of the top of the stirring communication plate 41 is evenly fixed and communicated with a protective ventilation assembly 42, and the right end surface of the stirring communication plate 41 is ...
Embodiment 2
[0041] Such as Figure 3-5 As shown, on the basis of Embodiment 1, the present invention provides a technical solution: a biochemical test stirring device, the protective ventilation assembly 42 includes a discharge inner chamber 421, the bottom of the discharge inner chamber 421 is fixed to the stirring communication plate 41 and In communication, a discharge piston rod 422 runs through and is slidably connected to the inside of the discharge cavity 421 .
[0042] The top end of the discharge piston rod 422 located outside the discharge cavity 421 is fixedly connected with a restricting top cap 423 , and the conical surface of the bottom of the restricting top cap 423 is uniformly provided with dispersion guide grooves 424 . Ensure the uniformity of the air sprayed around, and further improve the uniformity of air stirring.
[0043] The contact pressure plate 43 includes a contact pressure plate 431, the right end of the contact pressure plate 431 is fixed and communicated w...
Embodiment 3
[0048] Such as Figure 6 As shown, on the basis of Embodiment 1 and Embodiment 2, the present invention provides a technical solution: a biochemical test stirring device, the air booster mechanism 5 includes a sealed cylinder 51, and the inside of the sealed cylinder 51 is penetrated and slidably connected There is a booster insertion rod 52 , and an inner conducting groove 53 is arranged at the middle position inside the booster insertion rod 52 . Stirring of biological fluid is achieved by high-pressure air, which reduces the damage of hard mechanical mechanism to biological cells and improves the uniformity of stirring.
[0049] The side of the booster plunger 52 located outside the sealed cylinder 51 adopts a slope structure, and the top of the slope of the booster plunger 52 is fixedly connected with a contact pressure transmission block 54, and the bottom of the booster plunger 52 corresponds to the inner conduction groove 53 A pressure switch 55 is fixedly communicated...
