Abstract
The invention discloses a presentation device of reading of an analog ammeter and a voltmeter. The presentation device comprises a panel and a dial. The panel and the dial are arranged together through a knob, and the panel is provided with a sectorial dial window. The panel is in a rectangular shape, the dial is in a circular shape, a center hole is formed in the center of the dial, and a pointer knob is arranged on the center hole. A pointer limiter is arranged on the back face of the panel, a range window is formed below the panel, and an area for drawing binding posts is arranged below the range window. The center hole of the dial is provided with a pointer which can rotate freely, and two reading areas which are respectively an ammeter reading area and a voltmeter reading area are arranged on the dial. The presentation device of reading of the analog ammeter and the voltmeter is simple in structure, low in cost, convenient to use and strong in intuition. Range can be converted conveniently, a teacher can better conduct classroom teaching, and classroom efficiency is improved.
Description
Technical field
The present invention relates to a kind of apparatus for demonstrating, relate in particular to a kind of phenomenon that present electric current and voltage class demonstration table is separation that overcomes, usually teacher adopts apparatus for demonstrating separately to impart knowledge to students, it is very much loaded down with trivial details varying, and also can affect the defective of classroom instruction benefit and a kind of indicator type current meter, the voltage table reading apparatus for demonstrating that provide.
Background technology
Indicator type current meter, voltage table are Middle School Physics chamber Experiments of Electricity instruments commonly used.Indicator type current meter has two ranges of 0.6A, 3A, and voltage table has two ranges of 3V, 15V.The reading of indicator type current meter, voltage table be junior middle school's electricity must learn content, usually teacher adopts apparatus for demonstrating separately to impart knowledge to students, it is very much loaded down with trivial details varying, and also can affect the classroom instruction benefit.
Summary of the invention
It is the phenomenon of separating that technical matters to be solved by this invention is to overcome present electric current and voltage class demonstration table, usually teacher adopts apparatus for demonstrating separately to impart knowledge to students, it is very much loaded down with trivial details varying, and also can affect the defective of classroom instruction benefit and a kind of indicator type current meter, the voltage table reading apparatus for demonstrating that provide.
The present invention solves above-mentioned technical matters by following technical proposals: a kind of indicator type current meter, voltage table reading apparatus for demonstrating, described apparatus for demonstrating comprises panel and index dial, panel and index dial are installed together by a knob, have fan-shaped index dial window on the described panel; Described panel is rectangle, described index dial is circular, the center of described index dial has center pit, indicator knob is installed on the center pit, and panel back is equipped with the pointer stop, and the below of panel has the range window, the range beneath window is provided with the zone of picture binding post, the pointer that can rotate freely is installed on the center pit of described index dial, and described index dial is provided with two reading zones, is respectively reometer reading zone and voltage table reading zone.
In specific embodiments of the invention, described panel top has two hanging holes of whole device being hung up demonstration.
Positive progressive effect of the present invention is: indicator type current meter provided by the invention, voltage table reading apparatus for demonstrating are simple in structure, with low cost, easy to use, and intuitive is strong, and the range conversion is convenient, are conducive to teacher and carry out classroom instruction, improve classroom efficiency.
Description of drawings
Fig. 1 is the structural representation of panel of the present invention.
Fig. 2 is the structural representation of index dial of the present invention.
Embodiment
Provide preferred embodiment of the present invention below in conjunction with accompanying drawing, to describe technical scheme of the present invention in detail.
Fig. 1 is the structural representation of panel of the present invention, Fig. 2 is the structural representation of index dial of the present invention, shown in Fig. 1-2: a kind of indicator type current meter provided by the invention, voltage table reading apparatus for demonstrating, described apparatus for demonstrating comprises panel 1 and index dial 2, both are installed together panel 1 and index dial 2 by a knob 9, have fan-shaped index dial window 3 on the panel 1; Panel 1 is rectangle, described index dial 2 is circular, the center of index dial 2 has center pit, indicator knob is installed on the center pit, and panel 1 back is equipped with pointer stop 6, and the below of panel 1 has range window 7, range window 7 belows are provided with the zone 8 of picture binding post, the pointer 5 that can rotate freely is installed on the center pit of index dial 2, and index dial 2 is provided with two reading zones, is respectively reometer reading zone and voltage table reading zone.
Indicator type current meter, voltage table are Middle School Physics chamber Experiments of Electricity instruments commonly used.Indicator type current meter has two ranges of 0.6A, 3A, and voltage table has two ranges of 3V, 15V.The reading of indicator type current meter, voltage table be junior middle school's electricity must learn content, usually teacher adopts apparatus for demonstrating separately to impart knowledge to students, it is very much loaded down with trivial details varying, and also can affect the classroom instruction benefit.
The present invention unites two into one indicator type current meter reading apparatus for demonstrating and pointer voltage meter reading apparatus for demonstrating, and its structure is comprised of parts such as panel, pointer and movable index dials.Panel is vertical rectangle (tens of centimetres approximately of the length of side), hanging hole is put so that hang up in the upper end, the panel middle upper part has to show the fan-like pattern window of ammeter index dial, the below is equipped with three binding posts side by side, the binding post on the left side is black, be marked with on the limit " one " number, two on the right is red, respectively has to show the fenestella of 0.6A, 3A or 3V, 15V range on the limit.There is pointer the back of fan-like pattern window, and the end of pointer is fixed on the circle centre position of the fan-shaped window of panel central authorities, and when the knob that arranges before its panel of turn, pointer can be done in fan-shaped window clockwise or counterclockwise rotation.Fan-shaped window two ends respectively are equipped with the pointer stop means behind the panel, so that the pointer slewing area only is limited within the fanlight mouth.The plectane center of being decorated with in opposite directions up and down reometer, voltage table index dial and 0.6,3 and 3,15 printed words is fixed on the rear end in indicator knob axle center, but plectane can sway in same plane.In the time of when the rotation plectane places the fan-shaped window of panel by the reometer index dial in the middle of, the range display window of panel below just in time exposes 0.6 and 3 printed words; Plectane rotates 180 when spending again, and panel window then shows index dial and the range thereof of voltage table.
This indicator type current meter, voltage table reading apparatus for demonstrating are simple in structure, with low cost, easy to use, and intuitive is strong, and the range conversion is convenient, are conducive to teacher and carry out classroom instruction, improve classroom efficiency.
More than show and described ultimate principle of the present invention and principal character and advantage of the present invention.The technician of the industry should understand; the present invention is not restricted to the described embodiments; that describes in above-described embodiment and the instructions just illustrates principle of the present invention; without departing from the spirit and scope of the present invention; the present invention also has various changes and modifications; these changes and improvements all fall in the claimed scope of the invention, and the claimed scope of the present invention is defined by appending claims and equivalent thereof.
