Detailed description of the invention
The present invention is further detailed explanation for the embodiment be given below in conjunction with accompanying drawing.
Seeing shown in Fig. 1-10, disposable adjustable syringe, including scale set 1, screw mandrel 2, upper casing 3, pen core support 4, end
Lid 5 and lower casing 6, described upper casing 3 is provided with upper casing through hole 31, and lower casing 6 is provided with lower casing through hole 61, and pen core support 4 is provided with medicine bottle and accommodates
Hole 44, described upper casing 3 and lower casing 6 all with pen core support 4 periphery card dress, described scale overlaps 1 and is positioned at upper casing through hole 31, upper casing 3
Upper casing through hole 31 inwall be provided with sliding projection 311, scale overlaps 1 periphery and is provided with the limit convex that 311 slidings protruding with sliding are connected
Block 13, described scale set 1 is sleeved on screw mandrel 2, threadeds with screw mandrel 2, and described screw mandrel 2 stretches into the medicine bottle of pen core support 4 to be held
In receiving bore 44, described screw mandrel 2 is provided with axial screw mandrel groove 21, and the bottom land of axial screw mandrel groove 21 is provided with unidirectional tooth bar 22, and pen core props up
One end of frame 4 has the positive stop hook 41 stretched in axial screw mandrel groove 21, and positive stop hook 41 is provided with the tooth coordinated with unidirectional tooth bar 22
Bar 411, described end cap 5 is installed on the other end of pen core support 4.
See shown in Fig. 4,7,8, in order to install upper casing 3, and firmly install.The periphery of described pen core support 4 is provided with
Shell card dress projection 42, upper casing 3 is provided with upper casing card holding trough 32 radially, and upper casing card dress projection 42 is installed on upper casing card holding trough 32
In.
See shown in Fig. 3,7,8, in order to install lower casing 6, and firmly install.The periphery of described pen core support 4 is provided with down
Shell card dress projection 43, lower casing 6 is provided with lower casing card holding trough 62 radially, and lower casing card dress projection 43 is installed on lower casing card holding trough 62
In.
Seeing shown in Fig. 7,8,9, the other end of described pen core support 4 is provided with toothed taper hole 45, and one end of end cap 5 has
The toothed conehead 51 coordinated with taper hole 45.End cap 5 is convenient to mount and dismount, and fixation, such that it is able to make to be arranged on end cap 5
Clamped bottle 9 fixation, will not rock so that injection precision improve.
Seeing shown in Fig. 5,6,7,8, the end face of described pen core support 4 is provided with the first limiting tooth 46, described scale set 1 with
The contact surface of the end face of pen core support 4 is provided with the second limiting tooth 11.When operator rotate lower casing 6, pen core support 4 rotates
During, the first limiting tooth 46 coordinates with the second limiting tooth 11, rotates a number of teeth, will show accurately in the periphery of upper casing 3
Show, improve injection precision.
Seeing shown in Fig. 5,6,10, one end of described scale set 1 has internal thread segment 12, internal thread segment 12 and screw mandrel 2 spiral shell
Stricture of vagina connects.So when screw mandrel 2 rotates, scale set 1 rotates owing to being limited by upper casing 3, scale set 1 can only do rise or
Down maneuver.
See shown in Fig. 1,2,3, comfortable in order to make operator use, also include button 7, described button 7 is fixing to be connected
On the other end of scale set 1.
See Fig. 2, shown in 3, also include that syringe needle 8, the other end of described end cap 5 are male end 52, syringe needle 8 and external screw thread
Hold 52 threaded.Syringe needle 8 has internal thread hole, with end cap 5 fixation, is convenient to mount and dismount, and improves injection efficiency.
See shown in Fig. 1,3,5, described upper casing 3 is provided with at lower casing 6 the upper casing scale viewing area 39 of circumference, institute
The other end stating scale set 1 is provided with axial scale viewing area 19.Upon injection, need to rotate lower casing 6, lower casing 6 and upper casing 3
Between relatively rotate, drive scale set 1 rising.Now operator can observe upper casing scale viewing area 39 He of upper casing 3
The scale change of scale viewing area 19 display of lower casing 6, the actual push-in stroke of medicament adds high scale set 1 equal to upper casing 3 scale
The scale of rising, improves the accuracy of injection further.
When the present invention uses, first the bottleneck of clamped bottle 9 is installed on end cap 5, then by end cap 5 by toothed conehead
On 51 taper holes 45 being installed on pen core support 4 other end, clamped bottle 9 is placed in the medicine bottle receiving hole 44 of pen core support 4, makes card
Formula bottle 9 fixation, also makes the subsequent action can the carrying out of accurate safety simultaneously.
The lower casing 6 of the present invention not only acts as the protection to syringe needle 8 and dust reduction capability, or the initial part of transmission.Injection
Time, lower casing 6 can be rotated, owing to lower casing 6 is provided with lower casing card holding trough 62 radially, the lower casing card dress projection 43 of pen core support 4
Being installed in lower casing card holding trough 62, therefore lower casing 6 drives the equidirectional rotation of pen core support 4.Have due to one end of pen core support 4 again
Having the positive stop hook 41 in the axial screw mandrel groove 21 stretching into screw mandrel 2, therefore pen core support 4 drives the equidirectional rotation of screw mandrel 2.Scale set
1 is sleeved on screw mandrel 2, threadeds with screw mandrel 2, and therefore screw mandrel 2 will drive scale set 1 to do ascending motion, and operator can
To observe the scale of scale set 1, when rising to user's required dosage, pressing the button 7, screw mandrel 2 guides at axial screw mandrel groove 21
Effect is lower keeps straight on downwards, and then the pushing block 10 propped up in clamped bottle 9 is injected.
Due to the fact that the bottom land of the axial screw mandrel groove 21 of screw mandrel 2 is provided with unidirectional tooth bar 22, the positive stop hook 41 of pen core support 4
It is provided with the tooth bar 411 coordinated with unidirectional tooth bar 22, cannot lift after screw mandrel 2 declines extruding medicinal liquid, it is impossible to return in situ, because of
This present invention is disposable syringe, safe and reliable.And screw mandrel 2 is threadeded with rotating to be of scale set 1, Ke Yiguan
Examining the scale injection dosage of scale set 1, injection precision is high, simple in construction, and assembling is reliable.
Above-described is only the preferred embodiment of the present invention, it is noted that for those of ordinary skill in the art
For, without departing from the concept of the premise of the invention, it is also possible to make some deformation and improvement, these broadly fall into the present invention
Protection domain.
