Electric counting component and the LCDs being connected with photoelectric counting component, LCDs are fixed on support;
Rotatably installed in the inside of support, counting plate component is tubular structure to counting plate component, and threaded rod stretches to
The inside of support and counting plate component is passed through, threaded rod coupled with counting plate component slippage, and support is threadedly coupled with threaded rod;Meter
Number disk component is at least cased with a counting plate, and the outer of counting plate is uniformly provided with some counting holes, and photoelectric counting component is provided with inspection
Gauge head, the position of detection head are matched with the position of counting hole.
Further, the inwall of counting plate component is conformed with, and threaded rod is provided with the groove coupled with projection matching.
Further, projection is strip, and projection is axially arranged along counting plate component, groove located at the periphery of threaded rod,
Groove threadingly bar it is axially arranged;The rotating shaft of threaded rod is with the rotating shaft of counting plate component on the same line.
Further, counting plate component is cased with counting plate I and counting plate II, mutually equal between counting plate I and counting plate II
OK, the quantity of detection head is 2, and detection head matches counting plate I and counting plate II respectively.
Further, the outer of counting plate I is provided with two circle counting holes, the circle of the center of circle of counting hole and counting plate I on counting plate I
Between the heart, counting plate I is divided into some deciles by line;
The outer of counting plate II is provided with two circle counting holes, on counting plate II the center of circle of the center of circle of counting hole and counting plate II it
Between line, between the center of circle of counting hole and the center of circle of counting plate I, projection of the line on counting plate II jointly will meter on counting plate I
Number disk II is divided into some deciles.
This utility model is had an advantage in that relative to prior art
1st, come video data by the way of LCDs, digital independent is directly perceived for this utility model;
2nd, in this utility model, photoelectric counting component monitors the position of counting hole by detection head, when threaded rod is rotated further
When driving counting plate to rotate, the position of counting hole changes, and the angle that counting plate is rotated is equal to the angle that threaded rod is rotated
The angle that threaded rod is rotated is converted into distance that screw thread moves up and down and then draws meter by calculating by degree, photoelectric counting component
In LCDs, this kind of structure has prevented the error that gap between digital wheel causes to amount data display, accurately can count
Calculate the action distance of threaded rod and then obtain out continuous data.
