Technical field
This utility model relates to electronic whiteboard technology field, a kind of instrument lifting pen height for measuring electronic whiteboard
Device.
Background technology
Lift pen height, also referred to as sense height, refer to taking the photograph of the infrared equipment on infrared electronic white board or optical electron blank
As equipment can sense maximum (far) distance between lettering pen and electronic whiteboard, that is, any dynamic within this distance
Make, writing and maloperation including lettering pen, can be set by infrared equipment or optics and perceive and trigger as normal
Signal processes.This index is for weighing infrared electronic white board and optical electron blank touch accuracy and the stability of performance
One of important parameter.Lift pen the most excessive or too small the most bad.Lift pen the most excessive time, lift pen every time and all must lift to compare
Height, relatively elaborate, especially to writing on blank and drawing, easily cause font or lines line；Lift pen the most too small time, frequently
Numerous pen of lifting is likely to result in font or contacts the reflection being likely to trigger electronic whiteboard unintentionally, causes unnecessary behaviour
Make.Lifting one of technical specification that pen height pays close attention to as manufacturer, it is good and bad that its height " size " is directly connected to blank touch-control performance.
Need to detect electronic whiteboard in process of production and lift pen height, it is ensured that the pen of lifting of electronic whiteboard highly reaches required precision；Meanwhile,
When choosing and using infrared or optical electron blank, needing to detect electronic whiteboard, to lift pen the most qualified, or measure it and lift
The size of pen height.Market also has measures the instrument lifting pen height, the such as patent of Patent No. CN 204007411 U, but
It is that it is to go to read measurement result by naked eyes, and is the quantity by several screw threads, the most easily produces error, and compares
It is cumbersome, to this end, we design a kind of instrument lifting pen height for measuring electronic whiteboard.
Utility model content
The purpose of this utility model is to provide a kind of instrument lifting pen height for measuring electronic whiteboard, above-mentioned to solve
The problem proposed in background technology.
For achieving the above object, the following technical scheme of this utility model offer:
A kind of instrument lifting pen height for measuring electronic whiteboard, including cylinder, the upper end connection of described cylinder has transparent
Supporting leg, be plugged with expansion link in described cylinder, the upper end of described expansion link is provided with draw-in groove, is provided with infrared in described draw-in groove
Linear distance sensor, the intracavity bottom of described cylinder is provided with the screwed hole running through cylinder, is plugged with threaded post in described screwed hole,
And the upper end of threaded post is against the lower end of expansion link, between lower end and the intracavity bottom of cylinder of described expansion link by spring even
Connect, and spring housing is connected in threaded post, be provided with groove in the middle part of the lower end of described expansion link, in described groove, be respectively equipped with controller
And accumulator, and the lower end of groove is provided with groove lid, the sidewall of described cylinder is provided with display screen, and the lower end of described threaded post is provided with
Spill spin block, described controller is electrically connected with infrared ray range sensor and display screen, and described accumulator is electrically connected with
Infrared ray range sensor, controller and display screen.
Preferably, described groove lid is threadeded with groove.
Preferably, the outer end of described spill spin block is circumferentially with burr.
Preferably, the upper end of described threaded post is circular arc.
Compared with prior art, the beneficial effects of the utility model are: this is used for measuring electronic whiteboard and lifts the instrument of pen height
Device, by rotating spill spin block, makes infrared ray range sensor slowly near electronic whiteboard, when electronic whiteboard senses, is
Distance to be measured, at this moment, directly reads measurement result by display screen, simple and convenient, reduces human error, and, stretch
Contracting bar is connected by spring with the bottom of cylinder, and so, infrared ray range sensor nearer it is to electronic whiteboard, the pulling force of spring
The biggest, the speed that infrared ray range sensor advances is the slowest, is more conducive to the raising of certainty of measurement.
Accompanying drawing explanation
Fig. 1 is this utility model structural representation.
In figure: 1 cylinder, 2 supporting legs, 3 expansion links, 4 draw-in grooves, 5 infrared ray range sensors, 6 screwed holes, 7 threaded post, 8
