Description

Bar shaped ergometer

Technical field

This utility model relates to physical experiment apparatus field, is specifically related to a kind of bar shaped ergometer.

Background technology

In Physical Experiment, bar shaped ergometer is as the instrument measuring class, it is necessary to assure its accuracy, but present bar shaped Ergometer is the most all directly by observing scale reading, there will be a lot of error, when bar shaped ergometer inclines in actual tests The power measured time tiltedly is the most inaccurate, causes the failure of experiment.

Utility model content

Technical problem to be solved in the utility model is that the ergographic reading of bar shaped is misread, the ergographic zero of bar shaped Problem, it is ensured that the numerical value measured is the power in horizontally or vertically direction.

To achieve these goals, the technical scheme that this utility model provides is:

Bar shaped ergometer, including fixing bar, fixing bar is fixed on the middle part of housing upper end, and the upper end of fixing bar connects Having draw ring, the lower end of fixing bar connects tension spring, and the other end of tension spring is connected on one end of active pull rod, movable The both sides, upper end of pull bar are respectively fixed with pointer, can be through induction apparatus during hand motion, and the other end of active pull rod connects to be had Hook；Numerical value plate is fixed on housing, and numerical value corruption is engraved in numerical value plate both sides, and display lamp is on numerical value plate, corresponding with numerical value respectively, Induction apparatus is to there being an induction apparatus below the lower section of numerical value plate, each numerical value, and zero display lamp is on numerical value plate；Power supply Switch and power supply are fixed on the upper left quarter of housing；Positive source connects on and off switch, and the other end of on and off switch connects induction apparatus, The other end of induction apparatus is connected with display lamp, and the other end of display lamp is connected with power cathode；Transparent cover plate coordinates with housing.

Concrete, transparent cover plate, transparent cover plate is transparent material, and housing have employed stainless steel.

Concrete, active pull rod is transparent seal bar, and equipped with blue liquid inside active pull rod, active pull rod is with blue The position of fluid parallel indicates vertical scale line b vertical with horizontal scale line a for horizontal scale line a.

This utility model design can be misread reading is avoided simultaneously easily numerical value in test, improves accurately Degree.

Detailed description of the invention

As it is shown in figure 1, bar shaped ergometer, including fixing bar 3.Fixing bar 3 is fixed on the middle part of housing 2 upper end, Gu The upper end of fixed pole 3 connects draw ring 1, and the lower end of fixing bar 3 connects has tension spring 4, the other end of tension spring 4 to be connected to live On one end of dynamic pull bar 8, the both sides, upper end of active pull rod 8 are respectively fixed with pointer 7, can be through induction apparatus when pointer 7 moves 15, the other end of active pull rod 8 connects hook 11；Numerical value plate 13 is fixed on housing 2, and numerical value 10 corruption is engraved in numerical value plate 13 Both sides, display lamp 9 is on numerical value plate 13, corresponding with numerical value 10 respectively, induction apparatus 15 in the lower section of numerical value plate 13, each numerical value 10 Lower section all to there being an induction apparatus 15, zero display lamp 9 on numerical value plate 13；On and off switch 5 and power supply 6 are fixed on housing The upper left quarter of 2；Positive source connects on and off switch 5, and the other end of on and off switch 5 connects induction apparatus 15, another of induction apparatus 15 End is connected with display lamp 9, and the other end of display lamp 9 is connected with power cathode；Transparent cover plate 12 coordinates with housing 2.

Before measurement, pointer 7 is zero graduation line when, and zero display lamp 14 will be light, reminds experimenter's pointer 7 Make zero, can normally work.

Induction apparatus 15, below numerical value plate 13, has induction apparatus 15, pointer 7 to rest on a certain numerical value below each numerical value 10 10 position time, induction apparatus 15 will connect, circuit ON simultaneously, will be bright with the display lamp 9 corresponding to numerical value 10, and light is not Also can clearly reading in the case of Hao.

Transparent cover plate 12 is transparent material, when bar shaped ergometer breaks down it will be clear that failure cause, same Time housing 2 have employed stainless steel, enhance service life.

On and off switch 5 can be able to be turned off in the not used time, it is possible to saves energy with the break-make of control circuit, so that battery Reach longer working life.

Active pull rod 8 is transparent seal bar, and active pull rod 8 is internal equipped with blue liquid 16, active pull rod 8 and blue liquid Position that body 16 is parallel also indicates vertical scale line b18 vertical with horizontal scale line a17 for horizontal scale line a17, no matter bar shaped Ergometer vertically uses or level uses, and can guarantee pulling force by observing blue liquid 16 with horizontal relation Vertical and horizontal.

The foregoing is only preferred embodiment of the present utility model, not in order to limit this utility model, all at this Any amendment, equivalent and the improvement etc. made within the spirit of utility model and principle, should be included in this utility model Protection domain within.
