Background technology
Liner agency is the very important apparatus in microbial inoculant, culture, separation and detection.At present, microorganism connects
Kind, culture, separation and detection are rule using manual method, i.e. the hand-held ring of ruling of laboratory technician is rule in media surface,
And the line ring is the rigid mechanism without elasticity, and the contact surface with culture medium can not be adjusted in line, is easily scratched
Culture medium.
A kind of adaptive liner agencies of gravity of patent ZL 2015207610145 disclose a kind of liner agency, and the mechanism will
The traditional approach of artificial crossed is changed to the automated manner of machinery line, still, in scratching process, can only once pick up one and draw
Wire loop, it is necessary to repeat the action of line next time after line one is taken turns, time-consuming slightly long, ring of once ruling can only be used by once ruling,
Complete after once ruling, need one new disposable line ring to be installed or to original non-disposable stroke in same position again
Wire loop sterilization is rule again.
The content of the invention
Ring of once ruling can only be used to solve once to rule existing for prior art liner agency, is completed after once ruling,
Need that one new disposable line ring is installed in same position again or original non-disposable line ring sterilization is rule again
The problems such as, the utility model proposes a kind of microorganism line ring automatic dialing unit.
The utility model microorganism line ring automatic dialing unit, including drive device and liner agency;The driving dress

Close attachment screw, 19 be optoelectronic switch, 20 be protection cover-cap attachment screw, as illustrated, the utility model microorganism line ring
Automatic dialing unit, including drive device and liner agency;The drive device and liner agency threaded connection;The pen machine
Structure is two sets, the back-to-back both sides for being symmetricly set in drive device of two sets of liner agencies;The drive mechanism includes choosing
Select rotation driving first 6, rotation position instruction block 7, mounting blocks 10, stepper motor 13, shadow shield 15 and optoelectronic switch 19;The choosing
Rotation driving first 6, rotation position instruction block 7 and shadow shield 15 is selected to be fixedly connected with the output shaft of stepper motor 13;Stepper motor
13 are fixedly installed on mounting blocks 10;Optoelectronic switch 19 is fixedly installed on mounting blocks 10;The liner agency is connected by screw thread
It is connected in selection rotation driving first 6;The liner agency includes line ring 1, locking swivel nut 2, line ring guide sleeve 3, line ring
Balancing weight 4 and line ring installation swivel nut 5;One end of the line ring installation swivel nut 5 is fixing end, and the fixing end is revolved with selection
Turn driving head 6 to be threadedly coupled, the other end of line ring installation swivel nut 5 is line end, and the line end connects with the screw thread of locking swivel nut 2
Connect;The locking swivel nut 2 is hollow, and the line ring 1, line ring guide sleeve 3 and line ring balancing weight 4 pass through locking swivel nut
2;The line ring 1 is fixedly connected with line ring balancing weight 4 by cold punching or extruding;The outside suit line of the line ring 1
Ring guide sleeve 3, the gap of line ring 1 and line ring guide sleeve 3 coordinate.
In order to preferably implement this patent, those skilled in the art can need the line ring 1 of plurality of specifications when implementing
Line ring guide sleeve 3 is put in advance, and then, then will rule ring 1 and ring balancing weight 4 of ruling are fixed by cold punching or the method for extruding
Together so that line ring 1 can be in line ring guide sleeve 3 slidably.Second, by line ring 1, line ring guide sleeve 3
The sub-assembly formed with line ring balancing weight 4 passes through locking swivel nut 2, then locking swivel nut 2 is tightened in line ring installation swivel nut 5
On, when screwing locking swivel nut 2, the conical surface of the front end of locking swivel nut 2 is provided with breach, the conical surface extruding locking of line ring installation swivel nut 5
