Abstract
The invention discloses a simple and convenient homemade displacement meter which mainly comprises a sliding block, a sliding sheet, a spring, a voltmeter, a slide rheostat, a power supply, a switch and a lead, wherein the sliding block is connected with the sliding sheet; the sliding block and the sliding sheet are connected together on the slide rheostat and can freely move on the slide rheostat; the spring is connected with the voltmeter; one end of the spring is connected onto the sliding sheet; the other end of the voltmeter and the switch are connected together on the power supply; the slide rheostat is connected with the power supply in series; other parts are connected by the lead. Therefore the simple and convenient homemade displacement meter is formed. When the displacement of an object is required to be measured, the switch is closed; when the sliding block moves, that is, the displacement of the object changes, and the sliding sheet is driven to move, so that the resistance of the slide rheostat changes; once the resistance of the slide rheostat changes, the value of the voltmeter correspondingly changes; according to the change value of the voltmeter, a change value of the displacement of the object can be obtained. A method for measuring the displacement change of the object is simple and convenient and beneficial to the learning of people.
Description
Technical field
The present invention's design is a kind of displacement meter, especially a kind of simple and easy convenient self-control displacement meter of design.
Background technology
Along with developing rapidly of society, people more and more think little of the cultivation of manipulative ability, always like depending on modern high technology, but as student, I thinks that a lot of thing can not rely on science and technology, but need oneself actual hands-on, cultivate do-it-yourself ability; Secondly, as student, initiatively should go practice, the ability of oneself each side of aggressive cultivation, just be conducive to the development of self and the progress of society.Because the education resource of school is limited, a lot of experiment does not have complete equipment, and therefore, we can make a kind of easy displacement meter ourselves, are convenient to oneself study.
Summary of the invention
The present invention designs problem to be solved and is to provide simple and easy convenient self-control displacement meter.Its method for making is simple, and price is very cheap, uses also very convenient, for the development of student has a positive effect.
For solving above technical matters, the technical scheme of the present invention's design is as follows:
A kind of simple and easy convenient self-control displacement meter, primarily of slide block, slide plate, spring, voltage table, slide rheostat, power supply, switch, wire is formed.Described slide block is connected with slide plate, and slide block is connected on slide rheostat together with slide plate, and can move freely on slide rheostat; Described spring is connected with voltage table, and spring one end is connected on slide plate, and the voltage table other end is connected on power supply together with switch; Described slide rheostat and power sources in series; Again remainder wire is connected.Like this, just make simple and easy just survey and make displacement meter by oneself.
The beneficial effect of the present invention's design is: structure is simple, and easy to make, cost is low, simple to operation during use, for the actual operational capacity of student has a positive effect.
Accompanying drawing explanation
Accompanying drawing is the design concept schematic diagram of a simple and easy convenient self-control displacement meter.
Embodiment
Below in conjunction with drawings and Examples, the present invention's design is described further:
As shown in drawings, the present invention's design is primarily of 1 slide block, and 2 slide plates, 3 springs, 4 voltage tables, 5 slide rheostats, 6 switches, 7 power supplys, 8 wires are formed.Described 1 slide block is connected with 2 slide plates, and 1 slide block is connected on 5 slide rheostats together with 2 slide plates, and can move freely on 5 slide rheostats; Described 3 springs are connected with 4 voltage tables, and 3 spring one end are connected on 2 slide plates, and the 4 voltage table other ends are connected on 7 power supplys together with 6 switches; Described 5 slide rheostats and 7 power sources in series; Again remainder 8 wires are connected.Like this, just make simple and easy just survey and make displacement meter by oneself.
The present invention's design uses like this:
When the displacement of object will be measured, first Closing Switch; When slide block moves, namely the displacement of object changes, slide plate will be driven to move, the resistance of slide rheostat is changed, and the resistance of slide rheostat is once change, the value of voltage table will be made to change, by the changing value of voltage table, just can know that the change in displacement value that object occurs is how many.The method of this measurement ohject displacement change, simple and fast, is conducive to our study.
