Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further details, but following explanation is not the restriction to the utility model protection domain.
Fig. 1 is the packaging assembly schematic diagram of the utility model bacterium block sampler.As can be known from Fig. 1, this bacterium block sampler mainly contains inner prop 1, outer barrel 2, and spring 3 and perforating head 4 form.Wherein, outer barrel 2 is enclosed within the outside of inner prop 1, and inner prop 1 has circular interior column bracket 1, and outer barrel 2 has the outer barrel 2 of annular, so that apply power during compression.Spring 3 is positioned at outer barrel 2, in the space that inner prop 1 and perforating head 4 form.
Fig. 2 is the structural representation of the utility model inner prop.As can be known from Fig. 2, inner prop 1 comprises column bracket 11 in a circle, and diameter is less than the inner prop main body 12 of interior column bracket 11, and column cap 13 in being connected with inner prop main body 12 the other end.The shape of interior column cap 13 is the right cylinder with inner prop main body 12 coaxial line.
Fig. 3 is the structural representation of outer barrel of the present utility model.As can be known from Fig. 3, outer barrel 2 comprises the outer barrel 21 of an annular, and diameter equals outer barrel 21 internal diameter and the outer barrel main body 22 be connected with outer barrel 21.Outer barrel main body 22 is greater than inner prop main body 12 outer diameter for inner diameter.Outer barrel annulus 23 and outer barrel projection 24. is respectively equipped with at the inner and outer wall near outer barrel main body 22 the other end
Fig. 4 is the utility model spring used.The intermediate inner wall diameter of this spring is greater than the outer diameter of interior column cap 13, so that the passing of interior column cap 13.The two ends of spring 3 are connected respectively at the end face of outer barrel annulus 23 with inner prop main body 12, can carry out stretching or compressing.
Fig. 5-7 is the different perforating head of the utility model three kinds.As can be known from Fig. 5, this perforating head is the right cylinder that an inner diameter is greater than outer barrel outer diameter, is also provided with perforating head projection at one end inwall be connected with outer barrel main body 22, so that connect and prevent coming off in sampling process.Perforating head 4 shown in Fig. 6 and Fig. 7 is the molectron of two cylinders.Be provided with outer barrel projection 41 wherein equally with on the right cylinder inwall that outer barrel main body 22 connects.The two difference is the diameter of connecting cylinder body.In addition, the sampling end diameter of perforating head 4 can be determined according to actual needs, to adapt to the bacterium block of different size requirement.
In use procedure of the present utility model, inner prop 1, outer barrel 2, after spring 3 and perforating head 4 combine, outer barrel 2 is in same plane with the lower end of inner prop 1.Now spring is pressure-less state.When firmly pressing down inner prop 1, spring 2 is compacted, and inner prop 1 moves down, and interior column cap 13 is in same plane with perforating head 4 lower end.After beating and getting bacterium block, spring 3 stretches, and because inner prop main body 12 is connected with outer barrel main body 22 air-tight movable, after moving after inner prop main body 12, can form vacuum thus is adsorbed in perforating head 4 by bacterium block.When taking out bacterium block, by the cooperation of inner prop 1 and spring 3, bacterium block is released, and without the need to by means of other instruments.
The perforating head 4 of sampler can carry out being connected with sampler and can take off replacing.The various piece of sampler can be decomposed, so that cleaning and sterilization.
Although the utility model with preferred embodiment openly as above; but it is also not used to limit the utility model; any person skilled in the art; not departing from spirit and scope of the present utility model; can do various change and modification, what therefore protection domain of the present utility model should define with claims is as the criterion.
