Embodiment 1

As shown in Figure 1-3, a kind of digital display measure apparatus of youngs modulus, including host machine part 23 and telescopic system part 24, it is main Machine part 23 includes digital display electronic box 2, upright bar 8 and crossbeam 11, and the bottom of digital display electronic box 2 is fixedly connected with several footing leveling nails 1, The front of digital display electronic box 2 is equipped with power switch 3, power outlet A4, zero-setting button 14 and instrument and reinforces adjusting knob 15, digital display electronic box 2 upside is fixedly connected with workbench 5, and the upside of workbench 5 is fixedly connected with lower collet 6 and optical lever 7, and the two of lower collet 6 Side and be located at 5 upside screw of workbench be fixed with upright bar 8, crossbeam 11, the top of upright bar 8 are fixedly connected between two upright bars 8 It is equipped with upper cover 12, the downside screw of crossbeam 11 is fixed with upper grip 9 and digital display scale 10, and crossbeam 11, which is tightened up a screw, is fixed with power supply Socket B13, telescopic system part 24 include that lifting pedestal 16, lifting upright bar 17 and eyepiece adjust 18, and lifting pedestal 16 is built-in with Upright bar 17 is gone up and down, the top of lifting upright bar 17 is fixedly connected with restraining position ring block 20, is equipped with telescope 22, telescope 22 in stop collar 20 One end be arranged with eyepiece adjust 18, eyepiece adjust 18 and telescope 22 between be connected with limit pressing ring 21, the one of stop collar 20 Side is embedded with locking nail 19.

Lower collet 6 corresponds to each other setting with upper grip 9, is convenient for clamped wire, and locking nail 19 is threadedly coupled with stop collar 20, Convenient for adjusting, power outlet A4 and power outlet B13 pass through power supply line and connect with digital display scale 10, convenient for measurement.

Specifically, when the utility model is used, workflow are as follows:

1. installing instruments each component by diagram (attached drawing 1) position.

2. connecting each position tie of digital display scale 10, power supply line is turned on the power switch, and the digital spot of digital display electronic box 2 is bright.

3. installing steel wire between upper grip 9 and lower collet 6, when steel wire is installed, have to that steel wire is made to be in straight configuration, And upper grip 9 and the distance of lower collet 6 are consistent as far as possible, are convenient for survey calculation.

4. locking 11 locking type collet of crossbeam, keep instrument firm, to guarantee the stability of measurement data.

5. level meter is placed on workbench 5, adjustment footing leveling nail 1 makes instrument be in horizontality.

6. putting optical lever 7, in the translot of workbench 5, metapedes is placed in the recess on clip two foots, rotates optical lever 7, make the picture of digital display scale 10, be reflected on the graticle of telescopic system by optical lever 7, adjusts lifting pedestal 16, make digital display Scale 10 as high-visible (distance is between 0.35~0.4m).

7. unclamping telescopic system regulating nail, keep the horizontal line of graticle parallel with the horizontal line of digital display scale 10.

8. at this moment rotation instrument reinforces adjusting knob 15, steel wire is set to be in stress, when pulling force is shown as 1KG or 1.5KG Tested (purpose is that steel wire is made to be in good measuring state).

9. the horizontal line for adjusting the graticle that optical lever 7 makes the horizontal line of digital display scale 10 be directed at telescopic system determines good position, For 0.4mm steel wire, when being added to 5KG power, complete conjunction (is selected between 0~2 most all within scale convenient for the record of numerical value in this way It is good)

10. successively adding 0.5KG power, often plus once the displacement of scale label is simultaneously secondary from telescopic system is write down accordingly Scale value.(can also add up to read together and seek multiple averaging value).

11. substituting into formula: E=8FLD/ π db Δ x with by poor method processing data.

Pulling force suffered by F steel wire in formula, the length of steel wire between two collet of L, D are digital display scale 10 to 7 mirror surface of optical lever Vertical range, d are steel wire diameter, and Δ x(is this time measured and the difference of previous surveyors' staff numerical measuring) average value that repeatedly measures, B be 7 liang of front support points of optical lever perpendicular to 7 rear support point of optical lever distance.

It can be seen that whole experiment process may be implemented completely on the table, augmentor and display device design are integrated not only Measurement space is reduced, while also facilitating measurement, while observing that telescopic system is not only small in size also to facilitate measurement, entire instrument Device is designed as 24 two parts of host machine part 23 and telescopic system part, and instrument is succinct, convenient for storing the advantages of this is also this instrument.

Desk structure reduces space occupied, and reinforcing part is integrated with the design of numerical value explicit partial: now by workbench 5, Power switch 3 reinforces balancing controls, and worm and gear rotation reinforces sensor, reinforces rotation hand wheel and other matching components are all provided with Meter not only observes the variation of numerical value while reinforcing in this way, also reduces lab space, while novel looking in the distance in same cabinet 22 system work base of mirror and its lens barrel are the observation system of numerical value change, and volume also accordingly becomes smaller, and also shorten measurement distance, The requirement of distance is considered when avoiding testing in the past simultaneously when the measurement of Telescope 22.

Finally, it should be noted that the above descriptions are merely preferred embodiments of the present invention, it is not limited to this Utility model, although the utility model is described in detail with reference to the foregoing embodiments, for those skilled in the art For, it is still possible to modify the technical solutions described in the foregoing embodiments, or to part of technical characteristic It is equivalently replaced.Within the spirit and principle of the utility model, any modification, equivalent replacement, improvement and so on, It should be included within the scope of protection of this utility model.
