Abstract
The invention discloses an infusion regulator. The infusion regulator comprises a regulator shell, an infusion pipe, a pressing strip, and a baffle plate and a sliding device which are positioned on the same side of the two ends of the pressing strip; the infusion regulator is characterized in that the sliding device comprises a roller for regulating the infusion speed, a first groove for controlling the moving direction of the roller, and a centre shaft penetrating through the roller; the side surface of the first groove is shaped like a rack; the end part of the centre shaft is shaped like a gear; the end part of the centre shaft is positioned inside the first groove; the end part of the centre shaft is mutually meshed with the first groove. The infusion regulator has the advantages as follows: through the two gear-like ends of the centre shaft of the roller, the contact area of the center shaft with the rack inside the groove is increased and larger friction is generated, so that automatic rolling of the roller during long-time infusion can be prevented more effectively and the infusion stability is ensured to the maximum extent.
Description
Technical field
The present invention relates to a kind of infusion regulator, be specifically related to a kind of effectively anti-skidding infusion regulator.
Background technology
The infusion regulator using at present all exists along with passage of time, the problem that roller can slowly move up, and first this is unfavorable for temperature transfusion, the estimation of the last time that is secondly also unfavorable for having an intravenous drip.In the face of this problem, there is the scheme of many feasibilities.Technical scheme 201320094431.X in the art, it adopt be on press strip, to carry out gear, by the slow down lower upper slip of roller of the friction of the meshing generation on press strip and roller.This scheme can be improved the problem running at present really, but the contact surface of roller and press strip only has point of contact, and the place that frictional force produces is far apart from the axle center of roller, can not be well anti-skidding, transfusion with regard to the short time does not have any impact, once but transfusion time one is long, the drawback of this scheme will manifest.
Summary of the invention
For solving the deficiencies in the prior art, the object of the present invention is to provide a kind of infusion regulator that more effectively can be for a long time anti-skidding.
A kind of infusion regulator, comprise regulator shell, be positioned at described regulator shell inside tube for transfusion, press strip, be positioned at baffle plate and the carriage of the same side, described press strip two ends, it is characterized in that: described carriage comprise regulating transfusion speed roller, control the first groove of the described roller direction of motion and run through the axis of described roller; The side of described the first groove is spline-simulating, and the end of described axis is gear-like, and the end of described axis is positioned at the first groove, and the end of axis and the first groove mutually meshing; Described regulator shell is right-angled trapezium straight cylinder.
Aforesaid a kind of infusion regulator, is characterized in that: all there is second groove at the two ends of described press strip.
Aforesaid a kind of infusion regulator, is characterized in that: one end of described baffle plate is connected with regulator shell, and the other end is stuck in described the second groove.
Aforesaid a kind of infusion regulator, is characterized in that: described press strip is positioned at the regulator shell other 1mm of inner tube for transfusion place.
Aforesaid a kind of infusion regulator, is characterized in that: described the first groove has two, is separately positioned on the both sides of adjusting machine casing.
Usefulness of the present invention is: the axis two ends by roller are set to gear-like, increased the area of the tooth bar contact in groove, the frictional force producing is larger, and the automatic rolling of the situation bottom roller that can more effectively prevent from infusing for a long time, has guaranteed the stable of transfusion to greatest extent.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
The implication of Reference numeral in figure:
1-tube for transfusion, 2-regulator shell, 3-press strip, 4-the second groove, 5-baffle plate, 6-roller
7-the first groove, 8-axis.
The specific embodiment
Below in conjunction with the drawings and specific embodiments, the present invention is done to concrete introduction.
A kind of infusion regulator, comprise regulator shell 2, tube for transfusion 1, press strip 3, be positioned at baffle plate 5 and the carriage of press strip 3 the same sides, two ends, carriage comprises the roller 6 of regulating transfusion speed, the first groove 7 of fixed idler whell 6 directions of motion and run through the axis 8 of roller; The side of the first groove 7 is spline-simulating, and the end of axis 8 is gear-like, and the end of axis 8 is positioned at the first groove 7, and the end of axis 8 and the first groove 7 mutually meshing.
All there is second groove 4 at the two ends of press strip 3, and one end of baffle plate 5 is connected with regulator shell 2, and the other end is stuck in the second groove 4, and press strip 3 is flexibly connected with baffle plate 5.Such structure can prevent that press strip 3 is away from tube for transfusion 1, also guarantees that press strip 3 moves in suitable scope simultaneously.
The first groove 7 has two, is separately positioned on the both sides of adjusting machine casing 2.The design of bilateral can make frictional force further strengthen, thereby plays better skidproof effect.
More than show and described ultimate principle of the present invention, principal character and advantage.The technical staff of the industry should understand, and above-described embodiment does not limit the present invention in any form, and all employings are equal to replaces or technical scheme that the mode of equivalent transformation obtains, all drops in protection scope of the present invention.
Claims (5)
