Testing liquor dripping frame

Abstract

The invention relates to field of experimental instruments, and discloses a testing liquor dripping frame. The testing liquor dripping frame comprises a frame body, wherein a frame foot, a fixed plateand a lever are arranged on the frame body; a first transverse rack is glidingly connected with one end of the lever; a first hanging barrel is hinged to one end of the lever; a first bevel gear is meshed with the outer side of the first transverse rack; a vertical rack meshed with the first bevel gear is connected onto the first hanging barrel; a spring is arranged at the other end of the lever;a second transverse rack is connected with the spring; a second hanging barrel is hinged to the second transverse rack; a second bevel gear is meshed with the second transverse rack; a spool is fixedly connected onto the second bevel gear; a guy rope is wound on the spool; the guy rope is connected with a piston; a pipeline is arranged inside the frame body; the piston is positioned in the pipeline; the second transverse rack penetrates through the pipeline and is positioned below the piston; a spiral bent pipe is arranged at the lower part of the pipeline; a straight slot is formed in the wall of the bent pipe; a ball is arranged in the bent pipe; a supporting rod is connected onto the ball; and the supporting rod penetrates through the straight slot and is connected with a chuck. Through the frame, automatic changing of liquor bottles can be realized.

Description

technical field [0001] The invention relates to the field of experimental equipment, in particular to an experimental drug solution drip irrigation stand. Background technique [0002] In the process of drug reaction experiments in the laboratory, in order to ensure the accuracy and precision of the experiment, it is often necessary to add the test liquid to the reaction container many times, so as to facilitate the repeated experimental observation of the drug properties, so as to draw accurate experimental conclusions . The addition of the existing experimental liquid medicine is often carried out by the experimenter with a dropper. During the experiment, the liquid medicine is added repeatedly. It is easy to cause too much or too little addition, which will affect the accuracy of the experimental conclusion. In the prior art, there is also the technology of using the infusion stand for automatic drip irrigation of the medicinal liquid. The liquid medicine bottle is susp...

AI Technical Summary

Problems solved by technology

The addition of the existing experimental liquid medicine is often carried out by the experimenter with a dropper. During the experiment, the liquid medicine is added repeatedly. It is easy to cause too much or too little addition, which will affect the accuracy of the experimental conclusion

In the prior art, there is also the technology of using the infusion stand for automatic drip irrigation of the medicinal liquid. The liquid medicine bottle is suspended by the infusion stand, and the automatic drip irrigation of the medicinal liquid is carried out by using the infusion tube and the infusion needle, which can solve the cumbersome operation caused by manual dripping. , The problem of unstable addition

However, when using the infusion stand for drip irrigation of medicinal liquid, after the drip irrigation of a medicinal liquid is completed, the experimenter still needs to manually replace the medicinal bottle, which still cannot better meet the actual needs
