Embodiment
Now by reference to the accompanying drawings, preferred embodiment of the present utility model is elaborated.
The utility model embodiment provides a kind of instrument of lifting pen height for measuring electronic whiteboard, the sleeve 1 that comprises a hollow, and the movable proving installation being arranged on this sleeve, the test department of one end of this proving installation for highly measuring lifting pen, this test department is highly measured for the pen of lifting to electronic whiteboard; Described instrument comprises a support portion, when this support portion is used for measuring against electronic whiteboard screen cover; This support portion adopts transparent material to be made or its size is less than the critical induction size of electronic whiteboard, by electronic whiteboard, is not felt.This proving installation or sleeve can move up and down with respect to electronic whiteboard screen cover; During measurement, by brace abuts, on whiteboard screen face, this screen cover is as the reference field of measuring, and proving installation or sleeve are slowly mobile gradually near screen cover, when its arrival electronic whiteboard maximum is lifted pen height, thereby blocking infrared light, proving installation or sleeve felt by electronic whiteboard.
As shown in Figure 1, be the structural representation of the utility model preferred embodiment one.Support portion 31 is arranged at one end of sleeve 1, and this support portion 31 is positioned at one end identical with test department 211, and it is the support claw of making of transparent material; Because this support claw 31 adopts transparent material to be made, Infrared can be passed, and is not felt; It should be pointed out that the support portion that adopts transparent material to be made, its shape can be arbitrarily, as long as can be for supporting described surveying instrument in whiteboard screen face.Described support claw 31 is at least two, and the present embodiment is preferably three, and three support claws 31 can be guaranteed to support in one plane, makes to support more steadily and can better guarantee that surveying instrument is perpendicular on whiteboard screen face, reduces measuring error.
As shown in Figure 2, described sleeve 1 and proving installation 21 are threaded connection, and by threaded engagement proving installation 21, can rotate relative to sleeve 1, thereby can realize its relative sleeve 11, move up and down; Certainly, described sleeve 1 also can be slidably connected with proving installation 21, and this proving installation 21 can be relatively and sleeve 1 slip.Closer, the cylindrical sleeve 1 that described sleeve is hollow, it is provided with internal thread; Described proving installation is threaded column 21, and it is provided with external thread; By the cooperation of internal and external threads, threaded column 21 can with respect to sleeve 11 within it portion move up and down; This threaded column 21 is the test department 211 for stopping that infrared light is felt electronic whiteboard near this end of support claw; On described test department 211, be provided with the scale 41 for reading, scale 41 is lifted the measured value of pen for read electric blank.The other end of described threaded column 21 is provided with the rotating head 212 for rotating, and by manually rotating lightly this rotating head, the relative sleeve 1 of threaded column 21 is moved up and down; In described scale 41 settings and this test department 21, the every adjacent two scale mark sizes of space of this scale 41 are 1mm or 0.5mm or 0.2mm or 0.1mm, and the size of space is less, and the precision that pen height is lifted in measurement is higher; During test, by for the support claw 31 of sleeve 11 is resisted against on blank, then twist rotating head 212, make test department 211 edge down upon whiteboard screen face, when induced signal produces, stop the rotation and read measurement data.These data are the induction height of blank through converting.During survey measurements, take the lower end of sleeve 1 is reference, and the number m of the scales 41 that number exposes, draws test data f, then be converted into electronic whiteboard lift a pen height h; Conversion relation formula is: the height z-test data f that lifts pen height h=support claw.In the present embodiment, adjacent two scale marks of described scale 41 be spaced apart 0.5mm, the vertical height of support claw is 14.5mm, the scale mark number that during measurement, number obtains is 20, test data is 10mm, what draw lifts a pen height h=14.5-10=4.5mm.It should be noted that scale 41 also can comprise the numeral that scale mark and scale are corresponding, during reading, directly read the numeral on scale 41, can draw the size of lifting pen height.
As shown in Figure 3, be the structural representation of the utility model preferred embodiment two.Described support portion is arranged at one end of proving installation, and it is support column 32, and this support column 32 is fixedly connected on the lower end of described measurement mechanism, and during measurement, measurement mechanism is resisted against on electronic whiteboard screen cover by this support column 32; The sectional dimension of this support column 32 is less than 5mm, can be the cross section column that is arbitrary shape, square body for example, and trapezoidal cylinder, right cylinder etc., can be arranged on the optional position of stationary installation lower surface; The preferred support column 32 of the present embodiment is right cylinder, it is arranged on the shaft core position of stationary installation, the diameter of this support column 32 is 1～5mm, be preferably 1-2mm, the minimum critical induction of existing electronic whiteboard is of a size of 5mm, this support portion size is less than the critical induction size of electronic whiteboard, by electronic whiteboard, is not felt; On support column 32, be test department, be provided with the scale 42 for reading on this support column 32, read electric blank is lifted a size for pen height when measuring; Described sleeve 1 and proving installation 22 are threaded connection, and by threaded engagement sleeve 1, can rotate relative to proving installation 22, thereby can realize its relative proving installation 22, move up and down; Certainly, described sleeve and proving installation also can be slidably connected, and this sleeve can slide up and down with respect to proving installation.Further, described proving installation is cylindrical thread post 21, and it is provided with external thread; The cylindrical structural of described sleeve hollow, it is provided with internal thread.By the cooperation of internal and external threads, sleeve can move up and down in the inside of proving installation with respect to proving installation and block electronic whiteboard infrared light when measuring, thereby is felt by electronic whiteboard; Described scale 42 is arranged on the test department of support column 32, and read electric blank lifts pen height when measuring.As shown in Figure 4, the every adjacent two scale 42 line sizes of space of scale 42 are 1mm or 0.5mm or 0.2mm or 0.1mm, and the size of space is less, and the precision that pen height is lifted in measurement is higher; During test, by for the support column 32 of threaded column 12 is resisted against on blank, then turnbarrel 22, make the lower end of sleeve 0 edge down upon whiteboard screen face, when sleeve 0 blocks infrared light, when electronic whiteboard produces induced signal, stop the rotation and read measurement data.These data are the induction height of blank.During survey measurements, take the lower end of sleeve is reference, the number m of the scales 42 that number exposes, then the spacing distance that is multiplied by adjacent two scale marks draws test data f, and what be electronic whiteboard lifts a pen height h;
Should be understood that, above embodiment only, in order to the technical solution of the utility model to be described, is not intended to limit, for a person skilled in the art, the technical scheme that can record above-described embodiment is modified, or part technical characterictic is wherein equal to replacement; And all such modifications and replacement all should belong to the protection domain of the utility model claims.
