Embodiment
Embodiment：As shown in figs. 1-7, the present invention provides a kind of first embodiment of the infusion pump with rotation lock, its
Including：The medicine box 10 for housing medicinal fluid bag, the cover board 11 for being fixedly connected on 10 upper end of medicine box and being convexly equipped with latch portion 110, be arranged on
The top of cover board 11 and allow the rack 12 that latch portion 110 passes through, be fixed at 12 both sides of rack and mutually fasten front and rear half
Housing 13, by front and rear half shell 13 house and can with the rotation axis 21 of 110 snap fit of latch portion, allow 21 part of rotation axis to wear
The fixed frame 22 crossed, the lock hook part 23 for being housed and can be promoted by rotation axis 21 by fixed frame 22, driving rotation axis 21 are rotating
Key, can make fixed pin 24 and make 23 counter motion of lock hook part and be set in rotation axis 21 1 that rotation axis 21 stops rotating
The elastic component 25 at end.Its Chinese medicine box 10 and cover board 11 for ultrasonic bonding connection and form kit of parts, and front and rear half shell 13 is set
It is equipped with the locating slot 130 for housing fixed frame 22；Rack 12 is wriggling metal machine frame, and is connected with pump head component fixation (not shown)
Connect, and be provided with the perforation 120 for allowing latch portion 110 to pass through.Cover board 11 includes the latch portion 110 that protrusion is set, latch portion 110
Perforate is provided centrally with, and perforate is provided with an inclined-plane 112, the incline direction on inclined-plane 112 is obliquely.Elastic component 25 is preferably
Spring.
Rotation axis 21 includes spindle nose 212, the axis hole 210 and axis hole that are arranged on spindle nose 212 and allow fixed pin 24 to be inserted into
210 eccentric wheel 214, one end and eccentric wheels 214 adjacent and be axially connected with spindle nose 212 axially connect and diameter is more than eccentric wheel
214 connecting pin and the axially outer end positioned at the connecting pin other end, wherein axially outer end are provided with the keyhole coordinated with key.
