Specific embodiment
The following is a combination of the drawings in the embodiments of the present utility model, and the technical scheme in the embodiment of the utility model is carried out
It clearly and completely describes, it is clear that the described embodiments are only a part of the embodiments of the utility model rather than whole
Embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are without making creative work
All other embodiments obtained shall fall within the protection scope of the present invention.
- 3 are please referred to Fig.1, the utility model provides a kind of technical solution：A kind of liquid relief of the fine-tuning liquid level of drug inspection
Pipe, including air pressure adjustment pipe 1, rubber extruded ball 6 and hand-held fixed handle 10, the lower section of air pressure adjustment pipe 1 passes through separation baffles 2
It is interconnected with liquid storage pipe 3, and the outside of liquid storage pipe 3 is provided with graduation mark 4, while the lower section of liquid storage pipe 3 is connected with fluid suction head
5, the surface of separation baffles 2 is in honeycomb structure, and it is fixed on the lower section of rubber extruded ball 6, honeycomb structure permeability
Preferably, liquid to be measured is drawn convenient for passing through draught head, the lower end outer surface of liquid storage pipe 3 is in shape of threads, and itself and suction
Liquid first 5 cleans, rubber extruded ball 6 is arranged on air pressure adjustment to remove and install structure convenient for periodically dismantling down fluid suction head 5
The lower end of pipe 1, and rubber extruded ball 6 is internally provided with hard spheres 7, the diameter of rubber extruded ball 6 is more than air pressure adjustment pipe 1
