The device for injecting the nutrient solution into the test tubes comprises a shell body and a sliding box. Two side walls in the shell body are provided with sliding grooves. An input pipe is communicated on the top of the shell body. An air hole is arranged aside the input pipe. An output pipe is communicated at the bottom of the shell body. Sliding rails are arranged on two side walls of the sliding box. The sliding rails are inlaid in the sliding grooves and are matched with the sliding grooves in a sliding mode. An inlet hole is arranged on the top of the sliding box. An outlet hole is arranged at the bottom of the sliding box. Four sides of the sliding box are attached to the inner walls of the shell body and matched with the inner walls of the shell body in the sliding mode.
Description
Technical field
The utility model relates to a kind of instrument, particularly the device of instillation culture fluid in the test tube.
Background technology
In recent years, edible mushroom obtains people's popular welcome with its abundant nutritive value, and edible mushroom crowds in people's the diet in a large number, and the plantation edible mushroom also becomes a kind of Main Means of farmer richness.The plantation edible mushroom at first needs bacterial classification, and the method for making parent edible fungus kind commonly used is now: fix a funnel at iron stand, rubber hose of long tube place cover of culture fluid funnel below is housed in the funnel, a flow-stopping clip is fixed in the flexible pipe below.When injecting culture fluid to test tube, left hand is held test tube, and the mouth of pipe inserts the funnel flexible pipe in vitro up, and the right hand is clutched flow-stopping clip, makes culture fluid flow into test tube, unclamps flow-stopping clip after reaching aequum, and culture fluid stops to flow into.The weak point of this device is: because need the amount of the culture fluid of range estimation inflow test tube, so the speed of culture fluid injecting tube is slower.At low temperature season, the operating time one is long, and culture fluid solidifies easily.Simultaneously, because the artificial visually examine has error, loading amount is also inaccurate.When loading amount is on the low side, then make the inclined-plane of putting too thin, nutrition is few, and mycelia is difficult to normal growth; When loading amount was on the high side, the inclined-plane of putting shortened, and caused the waste of culture fluid.In addition, when the culture fluid injection rate of test tube too much is, need to refund unnecessary culture fluid in the funnel, be infected with easily when culture fluid is flowed through the test tube mouth, finally make bacterial classification contaminated.
Summary of the invention
The purpose of this utility model provide a kind of operation quick, quantize accurately and be difficult for polluting bacterial classification inject the device of culture fluid to test tube.
The technical solution of the utility model is: comprise housing and sliding case; The two side is provided with chute in the described housing both ends open, housing, and the housing top is connected with input pipe, and input pipe is provided with pore on one side, and the housing below is connected with efferent duct; The shell of described sliding case is positioned at housing, and the two side of sliding case is provided with slide rail, and this slide rail is embedded in the chute and with chute and is slidingly matched, and sliding case top is provided with hand-hole, and sliding case below is provided with portals; Sliding case four sides is affixed with inner walls and is slidingly matched with it, when sliding case slides into chute one end terminal, hand-hole on the sliding case just in time is communicated with input pipe, portalling on the sliding case sealed by housing, when sliding case slides into the chute other end terminal, hand-hole on the sliding case just in time communicates with pore, and portalling on the sliding case just in time is communicated with efferent duct.
Chute length on the housing is less than the length of place face, and the chute two ends are symmetrical.
Sliding case is made by transparent plastic material, and sliding case is provided with indicating graduation.
Because the structure that adopts housing and sliding case to match in the utility model, when sliding case slides into an end terminal, hand-hole on the sliding case just in time is communicated with input pipe, portalling on the sliding case sealed by housing, at this moment, culture fluid splashes into the sliding case from input pipe, when the amount of splashing into arrives assigned scale, stop to splash into, make again sliding case slide into the end of the other end, hand-hole on the sliding case just in time communicates with pore, and portalling on the sliding case just in time is communicated with efferent duct, and the culture fluid in the at this moment sliding case is from the efferent duct injecting tube.Aforesaid operations can be controlled the amount of splashing into of culture fluid rapidly under indicating graduation contrast, and measures relatively accurately, has reduced because the culture fluid injection rate is too many, returns the test tube of falling when to the pollution of culture fluid.

Embodiment
Below in conjunction with drawings and Examples the utility model is described in further detail, but does not consist of any restriction of the present utility model.Illustrated in figures 1 and 2, the utility model comprises housing 1 and sliding case 2.Described housing 1 both ends open, pack into from arbitrary end at two ends for sliding case 2, housing 1 interior relative two side is provided with chute 5, also can chute 5 be set at upper and lower two walls, the length of this chute 5 is less than the length of place face, chute 5 two ends are symmetrical, make the two ends of chute 5 can not extend the place face, and anti-on-slip case 2 skids off housing 1.Housing 1 top is connected with input pipe 3, and input pipe 3 is provided with pore 7 on one side, and housing 1 below is connected with efferent duct 4.The shell of described sliding case 2 is positioned at housing 1, and the two side of sliding case 2 is provided with slide rail 6, also can slide rail 6 be set at upper and lower two walls.Because sliding case 2 adopts transparent plastic to make, and has certain elasticity, sliding case 2 pushes in the housing 1 by force during assembling, and after among the slide rail 6 embedding chutes 5, slide rail 6 is slidingly matched with chute 5.Fig. 2 and shown in Figure 3, sliding case 2 tops are provided with hand-hole 8, and sliding case 2 belows are provided with portals 9, and sliding case 2 four sides are affixed with housing 1 inwall and are slidingly matched with it.When sliding case 2 one ends slided into chute 5 one ends terminal, owing to can not slide by chute 5 restrictions, at this moment, the hand-hole 8 on the sliding case 2 just in time was communicated with input pipe 3 again, slided portalling on the case 29 to be sealed by housing 1; When sliding case 2 slides into chute 5 other ends terminal, be subjected to equally chute 5 restrictions, the hand-hole 8 on the sliding case 2 just in time communicates with pore 7, and portalling on the sliding case 29 just in time is communicated with efferent duct 4.Sliding case 2 is provided with indicating graduation.
During operation, the funnel that culture fluid is housed is hung on the stand, be communicated with funnel and input pipe 3 with rubber hose, flow-stopping clip is contained on the rubber hose, promote sliding case 2 to housing 1 one ends slide into can not slide again till, at this moment, the hand-hole 8 on the sliding case 2 just in time is communicated with input pipe 3, and portalling on the cunning case 29 sealed by housing 1.When injecting culture fluid to test tube, clutch flow-stopping clip, make culture fluid pass through input pipe 3 and flow in the sliding case 2, when influx arrives assigned scale, unclamp flow-stopping clip and make culture fluid stop to flow downward.Then, promote sliding case 2 to housing 1 other end slide into can not slide again till, at this moment, hand-hole 8 on the sliding case 2 just in time communicates with pore 7, make sliding case 2 internal gas pressures with extraneous identical, portalling on the sliding case 29 just in time is communicated with efferent duct 4, makes culture fluids in the sliding case 2 by efferent duct 4 smoothly in the inflow test tubes.
