Including base, active clamp and weight tray, install the stand on the base, the crossbeam is installed to the stand upper end, and the rigid coupling steel wire that awaits measuring on the crossbeam, active clamp press from both sides and have tightly hung the peg on the couple of active clamp lower extreme at the lower extreme of steel wire that awaits measuring, and the weight tray sets up on the peg, and the peg lower extreme is provided with the attenuator, is provided with the water tank on the base, and the interior aquatic of water tank is placed in to the attenuator. The utility model discloses the steel wire that can rapid elimination arouses because of the increase and decrease weight from top to bottom the vibration with rock, simple structure, practical convenient, low cost, the effect is showing, is favorable to improving experiment measuring accuracy, utilizes the gravity of attenuator self moreover, adds the weight steel wire of flare -outing before need not testing in advance, has reduced the experimental procedure for the experiment progress.
Description
Technical field
The utility model relates to Young modulus instrument, specifically a kind of Young modulus instrument utilizing liquid resistance to eliminate the steel wire up-down vibration to be measured because increase and decrease counterweight causes and rock.
Background technology
The measurement of Young modulus is an important experiment in Experiment of College Physics, traditional pulling method measures tinsel Young's modules instrument and adopts optical lever principle, by increase and decrease counterweight, by Chroococcus minutus wiry by specular light lever amplification, and observed by the telescope and scale being placed in distant place, in experimentation, when increasing and decreasing counterweight easily there is up-down vibration and double swerve in steel wire to be measured, disturbance-observer, reading, cause reading difficulty and measure inaccurate, existing solution prevents its double swerve in counterweight bottom by spacing mode, but adjustment process bothers, take time and effort, and be difficult to the problem solving counterweight up-down vibration, still can cause the problem of reading difficulty.
Utility model content
The utility model is intended to solve the problem, thus provides a kind of quick elimination because of increase and decrease counterweight the steel wire up-down vibration to be measured caused and the Young modulus instrument rocked.
The utility model solves described problem, and the technical scheme of employing is:
A kind of Young modulus instrument, comprise base, active chuck and weight tray, base is provided with column, and column upper end is provided with crossbeam, crossbeam is connected with steel wire to be measured, active chuck is clamped in the lower end of steel wire to be measured, the hook of active chuck lower end is hung with peg, and weight tray is arranged on peg, and peg lower end is provided with damper, base is provided with water tank, and damper is placed in the water in water tank.
Adopt the utility model of technique scheme, compared with prior art, its outstanding feature is:
The steel wire up-down vibration because increase and decrease counterweight causes can be eliminated fast and rock, structure is simple, practical and convenient, with low cost, Be very effective, is conducive to the accuracy improving experiment measuring, and utilize the gravity of damper self, the stretching steel wire of front pre-add counterweight need not be tested, decrease experimental procedure, accelerate experiment progress.
As preferably, the utility model further technical scheme is:
Peg is provided with screw thread, screw thread is provided with clamp nut, weight tray is sleeved on peg by clamp nut.
Weight tray center is provided with the through hole coordinated with peg.
Screw thread is positioned on the medium position of peg.
Peg is connected by helicitic texture with damper.
Peg is positioned on damper body upper end center position.

Tank body is right cylinder.
Accompanying drawing explanation
Fig. 1 is the utility model example structure schematic diagram;
In figure: crossbeam 1; Column 2; Through hole 3; Clamp nut 4; Damper 5; Water tank 6; Steel wire 7 to be measured; Active chuck 8; Peg 9; Counterweight 10; Weight tray 11; Base 12.
embodiment:
Below in conjunction with embodiment, the utility model is described in further detail, and object is only to understand the utility model content better, and therefore, the cited case does not limit protection domain of the present utility model.
See Fig. 1, base 12 is provided with column 2, column 2 upper end is provided with crossbeam 1, crossbeam 1 is connected with steel wire 7 to be measured, active chuck 8 is clamped in the lower end of steel wire 7 to be measured, the hook of active chuck 8 lower end is hung with peg 9, peg 9 is processed with screw thread, screw thread is provided with clamp nut 4, weight tray 11 is disc, weight tray 11 center is processed with through hole 3, the through hole 3 of weight tray 11 is sleeved on peg 9 by clamp nut 4, peg 9 lower end is provided with damper 5 by helicitic texture, damper 5 body is square, peg 9 is positioned on damper 5 body upper end center position, base 12 is placed with water tank 6, water tank 6 body is the right cylinder adapted with damper 5 body, damper 5 is placed in the water of center in water tank 6, the size of damper 5 body will be convenient to freely up and down move in water tank 6, avoid colliding with the sidewall of water tank 6, damper 5 body adopts stainless steel to make, weight tray 11 adopts metal material to make, water tank 6 body adopts non-friable transparent material to make,
Only damper 5 need be put into water tank 6 before experiment, the height of regulating tank 6 position and water, damper 5 is immersed in water completely, after all keeping enough distances with water tank 6 sidewall bottom water tank 6, experiment can be started, during experiment, peg 9 is suspended on the hook of active chuck 8 bottom of steel wire 7 to be measured, counterweight 10 is added in above weight tray 11, be positioned at the below of weight tray 11 due to damper 5 and do not contact with steel wire 7 to be measured and weight tray 11, therefore can effectively avoid impacting experimental data in experimentation, when swing weight-adding 10 causes steel wire 7 up-down vibration to be measured and rocks, damper 5 thereupon also up and down and double swerve, but produce damping effect owing to there being the resistance of water and will make that damper 5 is static as early as possible to get off, and then steel wire 7 to be measured is also settled out, the problem which solves steel wire to be measured 7 up-down vibration because increase and decrease counterweight 10 causes and rock.
The utility model structure is simple, practical and convenient, with low cost, Be very effective, is conducive to the accuracy improving experiment measuring, and utilizes the gravity of damper self, need not test the stretching steel wire of front pre-add counterweight, decrease experimental procedure, accelerate experiment progress.
The foregoing is only the better feasible embodiment of the utility model, not thereby limit to interest field of the present utility model, the equivalence change that all utilization the utility model instructionss and accompanying drawing content thereof are done, be all contained within interest field of the present utility model.
