Description
Technical field
The utility model is related to medical product fields, especially a kind of novel infusion pump door-down switch mechanism.
Background technology
Infusion pump is a kind of external medical apparatus that can accurately control infusion flow rate.Existing flat horizontal type is defeated on the market
The door-down switch mode of liquid pump is all made of traditional rotary shaft coupling type toggle switch mechanism.Stirring rotary switch makes rotary shaft revolve
Turn, and then drives the opening and closing linked up with rotation and control hatch door being fixed thereon.To flat horizontal type infusion pump, when hook number is more than
For the moment, toggle switch must be perpendicular to the infusion direction placement of infusion pump, to make enabling torque make along the axial of hook shaft
With.Which increase length dimension of the infusion pump on infusion direction, while limiting the appearance cloth of flat infusion pump front panel
Office's design.In addition, traditional coupling type switching mechanism needs manual toggle switch when closing hatch door and applies thrust ability in fact
The closing of existing hatch door, operation are relatively inconvenient.
Invention content
The utility model will solve the disadvantage that the above-mentioned prior art, provide a kind of reasonable design, easy to operate novel defeated
Liquid pump door-down switch mechanism.
The utility model solves the technical solution of its technical problem use：This novel infusion pump door-down switch mechanism, packet
Protecgulum, decorative panel, rear cover are included, hook fixing plate is equipped in protecgulum, hook fixing plate is equipped with positioning pin, and hanger plate, which is equipped with, to be slided
Dynamic slot, positioning pin are matched with sliding groove medial surface, and spring is equipped between hanger plate rear and hook fixing plate, is set on hanger plate
There are two hook parallel to each other, matched with the door-plate fixing axle covered after, toggle switch end by connecting shaft with
Hanger plate connects, and toggle switch stage casing is equipped with the toggle switch shaft being fixed on protecgulum.
Preferably, the front end of hook is equipped with inclined-plane, inclined-plane is connect with hook side.
Utility model has the advantages that：One, door-down switch can be parallel to the infusion direction arrangement of infusion pump, in order to control
The design of panel provides space, keeps infusion pump front panel more attractive, is particularly suitable for flat horizontal type infusion pump；Two, door switch is set
Rotary type is counted into, user's operation is easy to；Three, a kind of door-down switch structure of parallel-moving type is provided, it only need to be to hatch door when closing hatch door
Apply thrust, you can realize automatically reseting for hatch door, easy to operate, reliability is high.

Specific implementation mode
The utility model is described in further detail below in conjunction with the accompanying drawings：
Embodiment：
It is solid to be equipped with hook in protecgulum 2 for a kind of novel infusion pump door-down switch mechanism, including protecgulum 2, decorative panel 3, rear cover 15
Fixed board 1, hook fixing plate 1 are equipped with positioning pin 1 and positioning pin 2 12, are set on hanger plate 8 there are two corresponding sliding groove,
Positioning pin 1, positioning pin 2 12 are matched with sliding groove medial surface, and respectively by positioning pin nut 1, positioning pin nut
26 limits are fixed, and spring 7 is equipped between 8 rear of hanger plate and hook fixing plate 1, set that there are two parallel to each other on hanger plate 8
Hook, matches, 4 end of toggle switch passes through company with door-plate fixing axle 1, the door-plate fixing axle 2 13 on rear cover 15
Spindle 9 is connect with hanger plate 8, and 4 stage casing of toggle switch is equipped with the toggle switch shaft 14 being fixed on protecgulum 2.
When use：
Open protecgulum：Such as Fig. 6, toggle switch 4 is rotated along the directions F1, toggle switch 4 is around being fixed on stirring out on protecgulum 2
Shaft 14 is closed to rotate.Toggle switch 4 drives the hanger plate 8 that links together by connecting shaft 9 with it along sliding groove to arrow
Direction is moved, and spring 7 is shunk by the extruding of hanger plate 8, and the hook on hanger plate 8 is detached from the door-plate being fixed on rear cover 15
Fixing axle, hatch door are opened.Toggle switch 4 is unclamped, hanger plate 8 is returned to initial position by the spring-force driven dual of spring 7.
Close protecgulum 2：As shown in fig. 7, vertically push protecgulum 2 along the directions F2, protecgulum 2 drive toggle switch 4, connecting shaft 9,
Hanger plate 8, hook fixing plate 1 are moved along the directions F2.When the hook inclined-plane 8-1 of hanger plate 8 encounters door-plate fixing axle, hook
Plate 8 is moved to the left under the action of power F2；When the hook side 8-2 of hanger plate 8 encounters door-plate fixing axle, 8 stop motion of hanger plate,
Under spring force, hook hook side 8-2 is matched with door-plate fixing axle.Hatch door is closed（As shown in Figure 9）.
In addition to the implementation, the utility model can also have other embodiment.It is all to use equivalent replacement or equivalent change
The technical solution to be formed is changed, the protection domain of the requires of the utility model is all fallen within.
