Description
Technical field
The utility model designs medical instruments field, specifically a kind of flow regulator.
Background technology
Traditional flow regulator is externally provided with pulley and limitation track in woven hose, by adjustable pulley on limitation track
The state that is extruded of position adjustments woven hose, so as to realize the control of liquid flowing speed in woven hose.This method accuracy compared with
Difference, can only be observed and be adjusted by the drop frequency of drop in doctor and nurse's observation transfusion funnel, both inaccurate or not
Convenient, for the less more accurate medicine of some consumptions, traditional flow regulator is not applied to more.
Therefore it provides a kind of precision is higher, indicative flow regulator more preferable, that operability is higher is current medicine instrument
The very active demand of field in the market.
Utility model content
The purpose of this utility model is to provide a kind of flow regulator, and upper-lower casing can be relatively rotated to control certain
Scope, places inordinate rotation.
The technical solution of the utility model is：A kind of flow regulator, including upper shell, lower house and rubber cushion, upper shell
Coaxially connected by connecting shaft between lower house, the end face of upper shell and the end face of lower house are oppositely arranged, and the rubber cushion is
Annular, rubber cushion is located between upper shell and lower house and around connecting shaft, and the end face of the upper shell is provided with inlet opening, rubber cushion phase
Fixed for upper shell, correspondence inlet opening is provided with through hole on rubber cushion, lower house is provided with the annular groove of width gradual change, the width of groove
End is provided with fluid hole, and through hole is engaged around the rotary motion trace of connecting shaft with annular groove, and the upper shell, which is provided with, to be used to limit
The first spacing preiection that upper shell and lower house are relatively rotated, the lower house is provided with second be engaged with the first spacing preiection
Spacing preiection, the lower house end face is connected provided with only liquid platform, only liquid platform one end with the narrow end of annular groove, and the other end is with going out liquid
Hole is connected.First spacing preiection and the second spacing preiection are in same track, are that the relative rotation of upper-lower casing is made that limitation,
Only the wide end of liquid platform and annular groove is located at the left and right sides of the second spacing preiection respectively, has reasonably separated flow regulator
Maximum stream flow position is with stopping flow position.
First spacing preiection is arc structure, including first end point and the second end points, the first end point and second
When spacing preiection is contacted, fluid hole is corresponding with through hole, when the second end points is contacted with the second spacing preiection, through hole and only liquid platform phase
Correspondence.When first end point and the contact of the second spacing preiection, fluid hole flow regulator corresponding with through hole is in maximum stream flow position,
When second end points is contacted with the second spacing preiection, through hole flow regulator corresponding with only liquid platform, which is in, stops flow position.
Second spacing preiection be T-shaped structure, the second spacing preiection include perpendicular to lower house circumference vertical arm and with
Vertical transverse arm, the length of the vertical arm is engaged with the thickness of the first spacing preiection.The inner side correspondence of second spacing preiection
Raised elastic mounting circle on upper shell, T-shaped structure matches with elastic mounting circle formation groove, the groove and the first spacing preiection
Close, improve upper shell and the relatively-stationary stability of lower house, so as to improve the stability that flow regulator adjusts flow.
The utility model has the advantages and positive effects of：Due to using above-mentioned technical proposal, flow regulator is most
Big flow position and stopping flow position are very fixed, effectively prevent flow regulator and excessively rotate the regulation mistake caused.
