The detection device used for the syringe putter of the syringe pump has simple structure, low cost and high detection precision.
Description
Technical field
The present invention relates to a kind of pick-up unit that is used for the injector push-rod of syringe pump.
Background technology
At present, the way of the testing agency that most syringe pump producer is in place to injector push-rod, generally all be in the parts of termination, to add a post rod mechanism, on the syringe pump gear train, increase by a cover linkage assembly again, when syringe is installed end face and is pushed up push rod in the termination, push rod drivening rod mechanism, linkage assembly just withstands screw, prevent that screw and leading screw from throwing off, thereby carry out normal injection, syringe post rod mechanism and the linkage assembly that mechanism adopts that be in place, this way is mechanism's complexity often, the requirement on machining accuracy height of mechanism has increased processing charges on the one hand, has improved the risk that syringe pump uses on the other hand.
Summary of the invention
The present invention is devoted to overcome the above-mentioned defective of prior art just and makes.The objective of the invention is to propose a kind of pick-up unit of simple in structure, cost is low and accuracy of detection the is high injector push-rod that is used for syringe pump.
For solving the problems of the technologies described above, the invention provides a kind of pick-up unit that is used for the injector push-rod of syringe pump, pick-up unit comprises: switch member, be located in the cavity of insulating end; Sliding part, but elastic telescopic be located in the cavity of insulating end, first end of sliding part stretches out from the insulating end end face, wherein, injector push-rod is connected in the end face of insulating end, and by compressing the first end touch-pressure switch spare of sliding part.
Preferably, be fixed with bearing in the cavity of insulating end, sliding part is located between bearing and the insulating end, and sliding part has the projection of touch-pressure switch spare, and the part between projection and bearing of sliding part is arranged with compression spring.
Preferably, switch member is a microswitch.
Preferably, be connected with web joint in the cavity of insulating end, switch member is fixed in web joint.
Preferably, insulating end is a working of plastics.
The invention has the beneficial effects as follows: because the present invention is provided with switch member and can compresses switch member in insulating end sliding part, come touch-pressure switch spare so compress sliding part by injector push-rod, thereby the height of switch spare electricity signal is frequently controlled the action of injecting injecting mechanism, so the present invention is simple in structure, cost is low and accuracy of detection is high.
Should be appreciated that above generality is described and the following detailed description is all enumerated and illustrative, purpose is for to the claimed further instruction that the invention provides.
Description of drawings
Accompanying drawing is formed the part of this instructions, with helping further understand the present invention.These accompanying drawings illustrate some embodiments of the present invention, and can be used for illustrating principle of the present invention with instructions.In the accompanying drawing:
Fig. 1 shows the synoptic diagram of the pick-up unit of the injector push-rod that is used for syringe pump of the present invention;
Fig. 2 is the inner structure synoptic diagram of the insulating end shown in Fig. 1.
Embodiment
Below in conjunction with accompanying drawing embodiments of the invention are elaborated, but the multitude of different ways that the present invention can be defined by the claims and cover is implemented.Identical in the accompanying drawings parts are represented with identical label.
With reference to figure 1 and Fig. 2, the pick-up unit that is used for the injector push-rod of syringe pump of the present invention is described, pick-up unit of the present invention comprises in the cavity that is arranged at insulating end 2: switch member 7, but be arranged at the sliding part 4 in this cavity elastic telescopic, and bearing 6, particularly, bearing 6 is arranged in this cavity relative with the end face interval of insulating end 2, sliding part 4 is arranged between the end face of bearing 6 and insulating end 2, and bearing 6 offers the through hole that cooperates with the two ends of sliding part 4 respectively with the end face of insulating end 2, but sliding part 4 has the projection 16 of touch-pressure switch spare 7, the part between projection 16 and bearing 6 of sliding part 4 is arranged with compression spring 5, this projection 16 can be compressed spring 5 compressions and be pressed on the end face of insulating end 2, thereby first end 13 of sliding part 4 can stretch out from the end face of insulating end 2.Also show injection injecting mechanism 1 among Fig. 1, injection injecting mechanism 1 comprises: support 9, leading screw 10 and be located at nut 11, insulating end 2 on the leading screw 10, wherein, leading screw 10 is connected on the support 9 rotationally by bearing, insulating end 2 is fixedlyed connected with the nut 11 on the leading screw 10, injector push-rod 8 has the installation end 15 with insulating end 2 clampings, injector push-rod 8 is connected in the end face of insulating end 2 by installation end 15, and can come touch-pressure switch spare 7 by first end 13 that compresses sliding part 4.Can find out also from Fig. 2 that in the cavity of insulating end 2, switch member 7 is fixed in web joint 3 to web joint 3 by screw retention, in addition, bearing 6 also be by screw retention in the cavity of insulating end 2.It may be noted that insulating end 2 is working of plastics among the present invention, switch member 7 can be microswitch or other available switch member among the present invention.
The workflow of pick-up unit of the present invention is described below: first end 13 that the installation end 15 of injector push-rod 8 is connected and compresses sliding part 4 with insulating end 2, projection 16 touch-pressure switch spares 7 by sliding part 4 make closing of circuit in the switch member, send the control system of a high electricity frequency signal to syringe pump, control system makes injection injecting mechanism 1 move by corresponding program, thereby finishes injecting of 8 pairs of syringe containers 14 of injector push-rod.If injector push-rod 8 is not connected with insulating end 2 or is not in place, sliding part 4 in this moment termination 2 is in the restoring force effect of compression spring 5 rejuvenate beginning position next time, switch member 7 is also return initial position thereupon, be that switch member 7 is not connected, send low electric signal frequently and control injection injecting mechanism and quit work, thereby stop to inject.
