Abstract
Present invention design discloses a kind of Full automatic displacement meter, mainly by sliding block, slide plate, spring, voltmeter, slide rheostat, power supply, switch, conducting wire composition.The sliding block is connected with slide plate, and sliding block is connected in together with slide plate on slide rheostat, and can be moved freely on slide rheostat；The spring is connected with voltmeter, and spring one end is connected on slide plate, and the voltmeter other end is connected in together with switch on power supply；The slide rheostat is connected with power supply；Rest part is connected with conducting wire again.In this way, simple just survey, which has just been made, makes displacement meter by oneself.When the displacement of object to be measured, first closure switch；When sliding block moves, that is the displacement of object changes, slide plate will be driven to move, the resistance value of slide rheostat is made to change, and the resistance value of slide rheostat once changes, it will change the value of voltmeter, by the changing value of voltmeter, just can know that the change in displacement value that object occurs is how many.The method of this measurement ohject displacement variation, it is simple and fast, be conducive to us and learn.
Description
Technical field
Present invention design is a kind of displacement meter, especially designs a kind of Full automatic displacement meter.
Background technology
With the rapid development of society, people increasingly think little of the culture of manipulative ability, always like dependent on the modern times
High-tech, but as student, I thinks that many things cannot rely on science and technology, but needs oneself actual hands-on, and culture is certainly
The ability that oneself starts；Secondly, as student, it should actively go to put into practice, the aggressive ability for cultivating oneself each side just has
Development and social progress beneficial to itself.Since the education resource of school is limited, no complete equipment is much tested, because
This, we can make a kind of easy displacement meter ourselves, learn convenient for oneself.
The content of the invention
Present invention design is problem to solve is that provide Full automatic displacement meter.Its production method is simple, price ten
Divide cheaply, use also easily, have a positive effect for the development of student.
For solution more than technical problem, the technical solution that the present invention designs is as follows：
A kind of Full automatic displacement meter, mainly by sliding block, slide plate, spring, voltmeter, slide rheostat, power supply, switch leads
Line is formed.The sliding block is connected with slide plate, and sliding block is connected in together with slide plate on slide rheostat, and can be in slide rheostat
On move freely；The spring is connected with voltmeter, and spring one end is connected on slide plate, and the voltmeter other end is connected in together with switch
On power supply；The slide rheostat is connected with power supply；Rest part is connected with conducting wire again.In this way, full-automatic position is just made
Move meter.
The advantageous effect that the present invention designs is：Simple in structure, easy to make, at low cost, when use, is simple to operate, is
The actual operational capacity of student has a positive effect.
Description of the drawings
Attached drawing is the design principle schematic diagram of a Full automatic displacement meter.
Specific embodiment
Present invention design is described further with reference to the accompanying drawings and examples：
As shown in drawings, present invention design is mainly by 1 sliding block, and 2 slide plates, 3 springs, 4 voltmeters, 5 slide rheostats, 6 open
It closes, 7 power supplys, 8 conducting wires are formed.1 sliding block is connected with 2 slide plates, and 1 sliding block is connected in together with 2 slide plates on 5 slide rheostats, and
And it can be moved freely on 5 slide rheostats；3 spring is connected with 4 voltmeters, and 3 spring one ends are connected on 2 slide plates, 4 electricity
The pressure table other end is connected in together with 6 switches on 7 power supplys；5 slide rheostat is connected with 7 power supplys；Rest part is led with 8 again
Line is connected.In this way, Full automatic displacement meter is just made.
Present invention design so uses：
When the displacement of object to be measured, first closure switch；When sliding block moves, i.e. the displacement of object changes, just
Slide plate can be driven to move, the resistance value of slide rheostat is made to change, and the resistance value of slide rheostat once changes, it will
Change the value of voltmeter, by the changing value of voltmeter, just can know that the change in displacement value that object occurs is how many.This survey
The method for measuring ohject displacement variation, it is simple and fast, be conducive to us and learn.
