Description
Technical field
The invention belongs to hand electric syringe arts, and in particular to the syringe needle of hand electric syringe a kind of and cylinder body
Detachable apparatus.
Background technology
Hand electric syringe be it is a kind of moved in cylinder body using motor pushing piston rod, to reach the mesh of drug injection
Electric tool.This syringe has adapted to the needs of large-scale animal farm.But compactness when being installed due to motoring syringe
It is needed with leakproofness, usual cylinder body and piston rod portion are not easy to assemble and disassemble, and which results in the inconvenience of cleaning and disinfection.
Currently, motoring syringe be all mostly can only complete machine dismounting, this to large-scale animal farm using when need frequent sterilization
Cleaning brings very big inconvenience.
Invention content
In order to realize motoring syringe simple and convenient disinfection and cleaning, electronic there is needle injection the present invention provides a kind of
Detachable apparatus, may be implemented in the case where motoring syringe complete machine is without dismounting, complete syringe cylinder body and piston
Partial dismounting brings great convenience to the cleaning and disinfection of motoring syringe.
The technical solution adopted by the present invention is：
A kind of electronic detachable apparatus for having needle injection, including injector housing, hexagonal fixing sleeve, syringe cylinder body,
Piston, piston rod, cambridge ring and locking nut；Three positioning of positioning hexagonal fixing sleeve are useful in the injector housing
Face, hexagonal are fixed with internal thread, the external screw thread connected with hexagonal fixing sleeve are useful on syringe cylinder body；Piston rod passes through six
Angle nut is connect with connecting plate；There is ball head structure in piston rod front end, for coordinating with the slot of piston rear end, ball when piston rod promotes
Head sliding in slot ensures that piston rod will not be blocked with piston, and piston is taken out when dismantling, without dismantling piston rod, hose and soft
Pipe fitting is connected by hose coupling with syringe cylinder body after being connected；Between having between the syringe cylinder body and injector housing
Gap, gap size is equal with cambridge ring front end, and cambridge ring prevents syringe cylinder body from occurring with injector housing by interference connection
It relatively rotates, the gib head of dismounting cambridge ring is useful on cambridge ring.
When mounted, first piston is connected with piston rod, then is connected through a screw thread and syringe cylinder body is allowed to be fixed with hexagonal
Cover closely coupled, there are gaps between injector housing and cylinder body at this time, then cambridge ring is fitted into gap, and pass through locking screw
Cambridge ring is pushed completely into gap by the cross force generated when mother's rotation, forms interference fit.
The beneficial effects of the present invention are：It is may be implemented in the present invention in the case where motoring syringe fuselage is not dismantled,
Only the dismounting of syringe cylinder body, glass tube and piston can be realized by rotating locking nut, facilitate and realize piston and glass
The cleaning and disinfection of pipe, installation are also very convenient.

Specific implementation mode
The specific implementation mode of the present invention is described with reference to the accompanying drawings and examples, to be better understood from this hair
It is bright.
The realization of the present invention uses following thinking：Syringe needs to make syringe cylinder body that can not turn after the completion of integral installation
It is dynamic, but so that syringe cylinder body is detached with hexagonal fixing sleeve and just need to rotate syringe cylinder body.So in the present invention, using
The method of interference fit joint makes syringe cylinder body that can not be rotated after installing by the assembly and disassembly of cambridge ring, and can in dismounting
With rotation, in addition for the installation of cambridge ring, the mode that locking nut transmits cross force is used, it is simple and effective.
Referring to Fig.1-5, a kind of electronic detachable apparatus for having needle injection of the present invention, including injector housing 4, hexagonal are solid
Surely set 2, syringe cylinder body 3, piston 8, piston rod 7, cambridge ring 5 and locking nut 6.It is fixed to be useful in the injector housing 4
Three positioning surfaces of position hexagonal fixing sleeve 2, hexagonal fixing sleeve 2 have internal thread, are useful on syringe cylinder body 3 and hexagonal fixing sleeve
The external screw thread of 2 connections；Piston rod 7 is connect by hex nut 1 with connecting plate 11；There is ball head structure in 7 front end of piston rod, for
The slot of 8 rear end of piston coordinates, and bulb can slide in slot when piston rod 7 promotes ensures that piston rod 7 will not be blocked with piston 8,
Can directly take out piston 8 in dismounting, hose 9 be connected with hose coupling 10 after by hose coupling 9 with syringe cylinder body 3
It is connected, needs first to remove hose coupling 10 in dismounting；There are two millimeters of gaps, gap between the syringe cylinder body 3 and shell 4
Size is equal with 6 front end of cambridge ring, and cambridge ring 6 prevents syringe cylinder body 3 from relatively rotating with shell 4 by interference connection,
The gib head of dismounting cambridge ring 5 is useful on cambridge ring 5；The transverse direction that the locking nut 6 is generated by worm drive when mounted
Cambridge ring 5 is pushed between shell 4 and syringe cylinder body 3 by power, and ensures to lock by the self-locking of screw thread.
When mounted, first the complete piston 8 of cleaning and sterilizing is connected with piston rod 7, then is connected through a screw thread and allows syringe
Cylinder body 3 and hexagonal fixing sleeve 2 are closely coupled, and there are minim gaps between injector housing 4 and cylinder body 3 at this time, then by cambridge ring 5
Cambridge ring 5 is pushed completely into gap by the cross force generated when being fitted into gap, and being rotated by locking nut 6, is formed interference and is matched
It closes.
In dismounting, first hose 9 and 10 connector of hose are removed, then locking nut 6 is screwed out, then by cambridge ring 5
Gib head extract cambridge ring 5, there are minim gaps between injector housing 4 and cylinder body 3 at this time, are rotated further by syringe cylinder body 3, make
Syringe cylinder body 3 is detached with hexagonal fixing sleeve 2, finally takes out piston 8, completes dismounting.
Entire assembling and dissembling process is convenient effectively, safe and reliable, and after installation is complete, syringe function realizes good, allomeric function
It realizes preferable.
