Description
Technical field
The utility model is related to drug auto-filling equipment fields, and in particular to a kind of variable quantitative medicinal liquid filling dress
It sets.
Background technology
In automatic fluid filling apparatus, filling amount can be changed by controlling flow and flow velocity, but equipment is complicated,
Manufacturing cost is high, and for liquid of this one kind of oral solution, packing specification is single, and quantitative filling can be used, but quantitatively fill
The filling amount of dress cannot control completely again, and when packing specification difference can only be repeatedly filling.Such as the drug filling 1 of filling 250ml
It is secondary, the drug of filling 500ml will divide 2 times it is filling, influence production efficiency.
Utility model content
The utility model provides a kind of variable quantitative medicinal liquid filling device, can quickly change quantifying for liquid drug.
The technical solution adopted in the utility model is：
First stage piston is arranged in a kind of variable quantitative medicinal liquid filling device, including piston cylinder, piston and push rod, the piston
Bar and second piston rod, second piston shank diameter are less than first stage piston bar, and second piston rod is connect with push rod, and second piston rod is set
Set multistage limit trip, push rod is hollow, matches with second piston shank diameter, push rod end set sliding groove slide groove shape with
Limit trip shape matches.The relative position of push rod and second piston rod, push rod and work are locked by the trip of different location
When stopper rod is fixed on different location, the volume in piston rod can generate variation.
Preferably, the limit trip is the block-shaped protrusion on second piston rod surface, and every grade of limit trip is in second piston
Bar surface is multiple along same circle distribution.Multiple trips can guarantee that fixation is more secured.
Preferably, the limit trip not at the same level is interlaced.When push rod is adjusted to certain level-one limiting card tenon of adaptation,
The control that can be realized to piston only need to be moved back and forth, is not interfered with other limit trips.
Preferably, connecting tube, the connecting tube connection inlet tube and drain pipe, the feed liquor are set at the top of the piston cylinder
Pipe is respectively provided with check valve with drain pipe.Piston rod only there are one connection liquid mouth, better tightness, piston any stroke all
It can realize that feed liquor or drain, check valve can be released in piston and will not be flowed back with liquid when resetting.
The utility model can realize the quantitative control to liquid drug, and quantitative size is adjustable.
Description of the drawings
Fig. 1 is the structural schematic diagram of the utility model；
Fig. 2 is push rod schematic top plan view；
Fig. 3 is push rod longitudinal sectional view；
In figure：1- piston cylinders, 2- pistons, 3- push rods, 4- connecting tubes, 5- inlet tubes, 6- drain pipes, 21- first stage pistons
Bar, 22- second piston rods, 23- level-one trips, 24- two level trips, 31- sliding grooves, 61- check valves.
Specific implementation mode
With reference to the accompanying drawings and examples, specific embodiment of the present utility model is described in further detail.
As shown in FIG. 1 to 3, a kind of variable quantitative medicinal liquid filling device, including piston cylinder 1, the interior setting of piston cylinder 1
Piston 2 has on piston 2 sequentially connected first stage piston bar 21 and second piston rod 22,22 diameter of second piston rod to be less than level-one
Piston rod 21, for second piston rod 22 along the multistage limit trip of extending direction distribution of bar, every grade of limit trip is circumferentially
Block-shaped protrusion, trip not at the same level is intertwined, as the two-stage in Fig. 1 limits trip, level-one trip 23 and two level card
Tenon 24 is interlaced.Second piston rod 22 connects push rod 3, and push rod 3 is hollow, can be slidably connected with second piston rod 22, push rod
3 setting sliding grooves 31, shape and the limit trip of sliding groove 31 match.Connecting tube 4 is arranged in 1 top of piston cylinder, and connecting tube 4 is same
When connection inlet tube 5 and drain pipe 6, inlet tube 5 is respectively provided with check valve 61 with drain pipe 6.
The use of the new type course of work is as follows：
Push rod is inserted in second piston rod 22, makes two-stage limit trip respectively by sliding groove 31, then rotating push-rod 3,
Make push rod 3 and 23 clamping of level-one trip, since 21 diameter of first stage piston bar is more than second piston rod 22, push rod 3 can be with when promoting
The compression for realizing piston 2 realizes that the whole of piston 2 is released with 23 clamping of level-one trip when push rod 3 exits.Rotating push rod 3, makes
Level-one trip 23 can be by sliding groove 31, push rod 3 and 24 clamping of two level trip, and the movement of piston 2, which does not generate, when pushed changes
Become, but when push rod 3 recycles, after level-one trip 23 with 24 clamping of two level trip, at this time due to being produced when push rod 3 moves
One section of idle stroke, therefore only release half way when the release of piston 3.The utility model is by changing being connected and fixed a little for piston rod
Realize the quantitative change of medicinal liquid filling amount.
