Description
Technical Field
The invention relates to auxiliary treatment equipment for burn and trauma patients, in particular to a pinch valve.
Background
In the treatment process of burn and plastic patients, cleaning, administration, oxygenation and other work are required, the work is generally carried out through an infusion tube, the amount of gas or liquid passing through the infusion tube needs to be controlled during the work, a pinch valve is used at the moment, the existing pinch valve basically controls a clamping rod through an air cylinder, and the impact force of the air cylinder on the clamping rod is too large in the operation process of the air cylinder, so that the infusion tube is easily damaged.
Disclosure of Invention
The present invention, in order to remedy the drawbacks of the prior art, provides a pinch valve that allows easy control of the throughput of liquid or gas.
The invention is realized by the following technical scheme:
a pinch valve is characterized by comprising a single chip microcomputer control system and a dustpan-shaped mounting plate consisting of an end plate, a side plate and a bottom plate, wherein a speed reduction motor is mounted on the end plate, a fixed cylinder is mounted on the bottom plate, and an L-shaped notch is formed in one end of the fixed cylinder, which extends out of the bottom plate; the output end of the speed reducing motor is fixedly provided with a rotating cylinder, the rotating cylinder is in threaded connection with a rear push rod, the rear push rod is connected with a front push rod through a spring, the rotating cylinder, the rear push rod, the spring and the front push rod are all positioned in a fixed cylinder, and the front push rod and the rear push rod are in key connection; and the single chip microcomputer control system is electrically connected with the speed reducing motor.
The fixed cylinder is provided with a through spline groove, the front push rod and the rear push rod are respectively provided with a screw rod, and the screw rods are in threaded connection with the threaded cylinders extending from the outside of the spline groove.
The output end of the speed reducing motor is provided with a longitudinal flat surface, and the output end of the speed reducing motor is fixedly connected with the rotating cylinder through a fixing bolt.
The front pushrod has an arcuate tip.
The contact surface of the fixed cylinder and the bottom plate is a plane.
The invention has the beneficial effects that:
the infusion tube clamping device can be used in cooperation with a treatment host machine or independently, under the control of a single chip microcomputer control system, the speed reduction motor drives the rotating cylinder to rotate, and the circular motion of the rotating cylinder is converted into the linear motion of the front push rod through the matching of the spline and the spline groove, so that the infusion tube is clamped or loosened.
Drawings
The invention is further described with reference to the accompanying drawings in which:
FIG. 1 is a schematic top view of the present invention;
FIG. 2 is a structural diagram of the front push rod in the direction B in FIG. 1;
fig. 3 is a schematic sectional view taken along the direction a-a in fig. 1.
In the figure, a side plate 0, an end plate 1, a bottom plate 2, a speed reducing motor 3, a flat surface 301, a fixing bolt 302, a rotating cylinder 4, a rear push rod 5, a spring 6, a front push rod 7, a screw rod 8, a threaded cylinder 9, a fixing cylinder 10, a flat surface 101, a spline groove 11 and a notch 12L.
Detailed Description
The drawings illustrate specific embodiments of the invention. As shown in fig. 1 to 3, the pinch valve comprises a single chip microcomputer control system and a dustpan type mounting plate, wherein the mounting plate is composed of a bottom plate 2, a side plate and an end plate 1, a speed reducing motor 3 is mounted on the end plate 1, an output end of the speed reducing motor 3 penetrates through the end plate 1, the output end of the speed reducing motor 3 is provided with a longitudinal flat surface 301, the output end is inserted into a rotating cylinder 4 and fixedly connected through a fixing bolt 302, and the inner end of the fixing bolt 302 abuts against the flat surface 301 after penetrating through the rotating cylinder 4. A fixed cylinder 10 is fixedly arranged on the bottom plate 2, the contact surface of the fixed cylinder 10 and the bottom plate 2 is a plane 101, and one end of the fixed cylinder 10 extends out of the bottom plate 2 and is provided with an L-shaped notch 12; a longitudinal spline groove 11 is formed in the fixed cylinder 10.
The rotating cylinder 4 is inserted into the fixed cylinder 10 and then is connected with a rear push rod 5 in a threaded manner, the top end of the rear push rod 5 is connected with a spring 6, the spring 6 is connected with a front push rod 7, and the end part of the front push rod 7 is an arched tip (as shown in figures 1 and 2).
A screw rod 8 is respectively fixed on the front push rod 7 and the rear push rod 5, the screw rod 8 is in threaded connection with a threaded cylinder 9 extending from the outside of a spline groove 11 to form a spline, and thus a key connection is formed between the fixed cylinder 10 and the front push rod 7 as well as the rear push rod 5, and the circular motion of the rotary cylinder 4 is converted into linear motion.
The invention can be installed on various therapeutic hosts to be used in a matching way, such as infusion, cleaning, oxygen filling and the like, when in use, the infusion tube is inserted into the L-shaped notch 12, the singlechip control system is started, the speed reducing motor 3 is controlled by the singlechip control system to operate, the speed reducing motor 3 drives the rotating barrel 4 to rotate when in operation, because the front push rod 7 and the rear push rod 5 are limited by the spline, the front push rod 7 and the rear push rod 5 can only do axial movement, and because of the existence of the spring 6, the front push rod 7 can buffer the extrusion of the infusion tube, and the violent impact on the infusion tube can not be formed.
Other technical features than those described in the specification are known to those skilled in the art.
