Detailed description of the invention
As shown in Figure 1, 2, a kind of injection novopen automatically, including the pen cap 1, interior axle 2, insulin medicated core 3, end cap knob
4 and syringe needle 5, one end of the pen cap 1 is provided with end cap knob 4, and the other end of the pen cap 1 connects insulin medicated core 3 and syringe needle 5, interior axle 2
Center is provided with through hole, is provided with injection screw rod 6 in through hole, and interior axle 2 periphery is arranged with torsion spring 7, and injection screw rod 6 is near insulin medicated core
The side of 3 is provided with the end that connects of injection push-plate 8, insulin medicated core 3 and the pen cap 1 and is provided with ratchet 9 and pawl disk 10, the ratchet of engagement
9 and pawl disk 10 be provided with the injection switch 12 that injection clutch 11 drives, the peripheral set of torsion spring 7 near the side of insulin medicated core 3
Being provided with the injection amount instruction dish 14 that coil 13 in key slot type is rotated, insulin medicated core 3 end is provided with injection screw rod backhaul pressure
Spring 15, injection clutch 11 end is provided with injection switch stage clip 16, and the outer wall of the pen cap 1 is provided with dose indication window 17, the pen cap 1
Outer wall is additionally provided with injection to be terminated to show labelling 18.
During use, rotating end cap knob 4, in driving, axle 2 front end pawl disk 10 is driven by coil 13 in key slot type simultaneously
Torsion spring 7 and dose instruction dish 14 together rotate, and dose instruction dish 14 acts at the pen cap 1 female thread and interior coil 13 outside keyway simultaneously
Under move to end while rotating, show injection amount by the outside indication window 17 of the pen cap 1.Interior axle 2 has through hole, inside has note
Medicine screw rod 6 band keyway, turn clockwise pawl disk 10, and the ratchet 9 engaged is opened due to front plan gear clutch injection
Closing and 12 close under the action of the spring, the end cap knob 4 that together rotates, injection amount instruction dish 14, torsion spring 7 can be positioned on the position of needs
Put, it is achieved injection amount sets.When the acupuncture treatment of injection pen is advanced, injection clutch 11 opened under block effect by injection switch 12,
Rotating through ratchet 9 female thread under torsion spring 7 gyroscopic action counterclockwise drives injection screw rod 6, injection push-plate 8 to move automatically
Injection.
Automatically the operation principle of injection novopen: insulin medicated core 3 passes through end convolution in loading insulin medicated core box
Ready-packaged joint connects in succession with the shaft of a writing brush, promotes injection screw rod backhaul clutch Guan Bi, thus retrain that injection screw rod 6 can only move can not
Rotate (outside keyway of injection screw rod 6 coordinates with keyhole in clutch).When in like manner changing insulin medicated core 3, spring makes clutch divide
From, screw rod back resetting free to rotate；When injection switch 12 does not works, spring pull switch clutch closes, and mandrel is by about
Shu Buneng rotates, and when rotating injection amount adjustment knob, in driving injection amount instruction dish 14 by mandrel, coil rotates, and drives torsion spring
7 work, make injection amount instruction dish 14 realize the aobvious of injection amount under an outer tube female thread and interior coil keyway act on jointly simultaneously
Show.In addition mandrel drives end pawl disk 10 to rotate the injection amount position stopping at needs under handle ratchet wheel 9 constraint in mandrel termination
Put.When opening injection and switching 2, separately, under the effect of torsion spring 7, mandrel 1 turns round and drives interior spine by pawl disk 10 clutch
Wheel 9 and mandrel revolution are made injection screw rod 6 move by mandrel inner hole thread, and realize automatic injection, injection by injection push-plate
In journey, injection amount instruction dish 14 realizes reset function simultaneously.
Described above it is merely exemplary for the purpose of the present invention, and nonrestrictive, and those of ordinary skill in the art understand,
In the case of the spirit and scope limited without departing from claims, many amendments can be made, change or equivalence, but all
To fall within the scope of protection of the present invention.
