Abstract
The utility model discloses an eccentric rotor wriggling injection pump, including the pump body, the level that sets up in the pump body arranges, with the liquid box in the infusion silicone tube be connected of liquid bag, characterized by: set up motor drive's eccentric main shaft in the top of infusion silicone tube, in different first, the eccentric sections of second of eccentric main shaft's eccentric distance, the same wriggling valve block of suit length, and first eccentric section is respectively gone up the cover and is equipped with four wriggling valve blocks, goes up the cover in the eccentric section of second and is equipped with three valve blocks of wriggling. The utility model discloses it is rational in infrastructure, safe in utilization, durable.
Description
Technical field
This utility model relates to a kind of eccentric rotor wriggling killer injecting pump.
Background technology
Existing killer injecting pump water flowing out structure uses water inlet valve block, water outlet valve block, extruding valve block action respectively to reach killer injecting pump injection purpose, and this structure oppresses silica gel tube for a long time due to valve block, easily causes silica gel tube fatigue and affects injection precision.
Summary of the invention
The purpose of this utility model is to provide a kind of rational in infrastructure, uses safety, durable eccentric rotor wriggling killer injecting pump.
Technical solution of the present utility model is:
A kind of eccentric rotor wriggling killer injecting pump, including the pump housing, the pump housing arranges the horizontally disposed transfusion silica gel tube being connected with liquid bag in liquid box, it is characterized in that: at the eccentric main axis being provided above motor driving of transfusion silica gel tube, on first, second eccentric segment that the eccentric distance of eccentric main axis is different, it is set with the wriggling valve block that length is identical, and on the first eccentric segment, is set with four wriggling valve blocks, the second eccentric segment is set with three wriggling valve blocks.
Described motor is connected to timing means；
This utility model is rational in infrastructure, uses safe, durable；From the radian of circle center deviation bottom eccentric main axis, rotating eccentric main axis when, the peristaltic valve sector-meeting being stuck in radian along radian slowly near eccentric main axis bottom centre, thus strain the distance of wriggling valve block and silica gel tube, make wriggling valve block compressing silica gel tube thus reach the purpose of killer injecting pump injection.Owing to eccentric main axis bias height and position differs, thus control the action sequencing of wriggling valve block and differ in position, reach the purpose of Inlet and outlet water.This utility model uses eccentric principle, and mechanical action reaches killer injecting pump injection purpose, it can be ensured that safe handling.
Accompanying drawing explanation
The utility model is described in further detail with embodiment below in conjunction with the accompanying drawings.
Fig. 1 is the structural representation of one embodiment of this utility model.
Fig. 2 is off the structural representation of main shaft.
Fig. 3 is off the working state schematic representation of main shaft.
Detailed description of the invention
A kind of eccentric rotor wriggling killer injecting pump, including the pump housing 4, the pump housing arranges the horizontally disposed transfusion silica gel tube 3 being connected with liquid bag in liquid box 5, the eccentric main axis 1 being provided above motor driving at transfusion silica gel tube, on first, second eccentric segment that the eccentric distance of eccentric main axis is different, it is set with the wriggling valve block 2 that length is identical, and on the first eccentric segment, is set with four wriggling valve blocks (A, B, C, D tetra-), the second eccentric segment is set with three wriggling valve blocks (E, F, G tri-).
Described motor is connected to timing means, can be timed the working time of motor, the most also can not set timing means.
During work, eccentric main axis rotates, ABCD wriggling valve block lifts, away from silica gel tube, EFG wriggling valve block is close and closes silica gel tube, and killer injecting pump starts to measure fills medicinal liquid to silica gel tube, eccentric main axis is rotated further, EFG wriggling valve block is away from silica gel tube, and ABCD wriggling valve block is close and extrudes silica gel tube discharge silica gel tube inner liquid medicine, makes medicinal liquid enter pencil and enters human body.
An above action cycle completes.
Claims (2)
1. an eccentric rotor wriggling killer injecting pump, including the pump housing, the pump housing arranges the horizontally disposed transfusion silica gel tube being connected with liquid bag in liquid box, it is characterized in that: at the eccentric main axis being provided above motor driving of transfusion silica gel tube, on first, second eccentric segment that the eccentric distance of eccentric main axis is different, it is set with the wriggling valve block that length is identical, and on the first eccentric segment, is set with four wriggling valve blocks, the second eccentric segment is set with three wriggling valve blocks.
