Description
Technical field
The utility model relates to chemical experiment teaching apparatus field, is specifically related to the device of chemical experiment quantitative liquid.
Background technology
Chemical experiment is all adopt following three kinds of modes to realize for quantitative liquid getting usually, the first is the mode adopting graduated cylinder, be about to need the liquid measured to pour in graduated cylinder, then glue head dropper is adopted to carry out quantitatively gradually, this mode is when measuring liquid, namely want pouring liquid to use glue head dropper quantitative again, the liquid volume accuracy obtained after so loaded down with trivial details operation is also lower, inefficiency; The second way is the mode adopting pipette and ear washing bulb, when utilizing pipette and ear washing bulb to measure liquid, owing to sucking liquid level height in the restive pipette of liquid rear right hand forefinger, the precision of quantitative liquid getting is lower, but also fixed volume liquid can only be measured, the third mode is the mode adopting pipette, when measuring liquid with pipette, accurately can not control the volume sucking liquid, be difficult to reach high-precision quantitative requirement.
Chinese patent literature CN 203816658U discloses a kind of quantitative liquid shifter, this quantitative liquid shifter utilizes screw stroke control device accurately to control the stroke of screw rod, piston can be driven when screw rod moves to move, imbitition when piston moves, the volume of its imbitition is the distance of screw rod movement and the product of piston cross-section face area, the stroke of screw rod accurately can be controlled by screw stroke control device, thus accurately control the volume of pipette liquid, the high-precision fixed requirement measuring liquid can be reached.Be adapted at chemical experiment teaching apparatus field to promote the use.
The shortcoming that above-mentioned patent exists is complex structure, bulky, and be not easy to mobile, operating process is loaded down with trivial details.
Utility model content
The utility model provides chemical experiment quantitative priming device, and the utility model solves the complex structure that existing same category of device exists, bulky, is not easy to mobile, the problems such as operating process is loaded down with trivial details.
For solving the problem, the utility model adopts following technical scheme: chemical experiment quantitative priming device, comprises a rifle shape main body 1, and rifle shape main body 1 gun barrel position is provided with a liquid storage cylinder 7, and there is liquid injecting mouth 8 liquid storage cylinder 7 front end; Have a piston 6 in liquid storage cylinder 7, piston 6 rear end connects a push rod 5, and rifle shape main body 1 side is positioned at the chute 10 having a horizontally set below liquid storage cylinder 7, is provided with a slide bar 4 in chute 10, and on the downside of slide bar 4, edge placement is equally spaced is provided with teeth groove 3; Teeth groove 3 is V-shaped, and its leading flank is vertical plane, trailing flank is inclined-plane; Slide bar 4 afterbody is connected with push rod 5 afterbody; Trigger 13 is installed in rifle shape main body 1 by bearing pin 11, bearing pin 11 is provided with a button spring 12, and button spring 12 two ends are fixedly connected with trigger 13 with rifle shape main body 1 respectively; Trigger 13 upper end coordinates with a certain teeth groove 3.
Advantage of the present utility model: overall in handgun shape, namely teacher or student's one hand can operate, and it is extremely convenient to act on.Overall structure is simple, and compact is lightweight, can move everywhere, and imbibition, injection process are conveniently.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation;
Fig. 2 is the A-A sectional view of Fig. 1.
Symbol description in figure: rifle shape main body 1, limited block 2, teeth groove 3, slide bar 4, push rod 5, piston 6, liquid storage cylinder 7, liquid injecting mouth 8, support ring 9, chute 10, bearing pin 11, button spring 12, trigger 13.
Detailed description of the invention
By best embodiment, the utility model is described in detail below.
As shown in Figure 1-2, chemical experiment quantitative priming device, rifle shape main body 1 is made for plastics, rifle shape main body and handgun shape close, have one handle and a gun barrel, rifle shape main body 1 gun barrel position is provided with a liquid storage cylinder 7, two support rings 9 are connected with above rifle shape main body 1, liquid storage cylinder 7 is installed in support ring 9, and support ring can be that two semi-ring docking form, and is fixed into a domain by screw.There is liquid injecting mouth 8 liquid storage cylinder 7 front end, and described liquid injecting mouth 8 is pyramidal structure.Liquid storage cylinder 7 is made for glass or transparent plastic.Have a piston 6 in liquid storage cylinder 7, piston periphery can arrange sealing ring, and piston structure is identical with piston structure in hydraulic cylinder, and piston 6 rear end connects a push rod 5, and putting back-end stretches out from the centre bore of liquid storage cylinder rear end cap.Rifle shape main body 1 side is positioned at the chute 10 having a horizontally set below liquid storage cylinder 7, is provided with a slide bar 4 in chute 10, and on the downside of slide bar 4, edge placement is equally spaced is provided with teeth groove 3; Teeth groove 3 is V-shaped, and its leading flank is vertical plane, trailing flank is inclined-plane, and such trigger upper end promotes the reach of leading flank band moving slide-bar, and when moving after trigger, can slip over from inclined-plane.Slide bar 4 afterbody is fixedly connected with by a montant with push rod 5 afterbody.Trigger 13 is installed in rifle shape main body 1 by bearing pin 11, bearing pin 11 is provided with a button spring 12, and button spring 12 two ends are fixedly connected with trigger 13 with rifle shape main body 1 respectively; Trigger 13 upper end coordinates with a certain teeth groove 3.Rifle shape main body 1 is positioned at teeth groove 3 rear position and is fixed with a limited block 2.During use, insert in liquid by liquid injecting mouth 8, pull back push rod 5 with hand, after being pulled to liquid storage cylinder 7 rear end cap position, filled by liquid, now trigger 13 upper end inserts in the most previous teeth groove 3.When needing fluid injection, extend into by liquid injecting mouth 8 in test tube or beaker, cocking 13, trigger 13 pushes away a slide bar 4 and moves forward, and push rod 5 moves forward thereupon simultaneously, and liquid extrudes by piston 6; Trigger stops after bumping against limited block 2, and like this after staff leaves trigger 13, trigger 13 return under button spring 12 acts on, trigger 13 is made up of plastic material, slightly elasticity, and trigger 13 upper end can slide backward a position, inserts in next teeth groove 3.So often pull a trigger, a certain amount of liquid can be injected.
Last it is noted that obviously, above-described embodiment is only for the utility model example is clearly described, and the restriction not to embodiment.For those of ordinary skill in the field, can also make other changes in different forms on the basis of the above description.Here exhaustive without the need to also giving all embodiments.And thus the apparent change of amplifying out or variation be still among protection domain of the present utility model.
