Description
Technical field
This utility model belongs to electronic engineering field, specifically a kind of electronic circuit demonstrator.
Background technology
In order to make student understand the ultimate principle about electronic circuit as soon as possible, grasp the method for designing about electronic circuit, occur in that various electronic circuit demonstrator, this kind of demonstrator is usually and is coated with the conductor wire more consistent with the pattern of the relevant electronic-circuit diagram of printing on textbook on the teaching substrate of one piece of student viewing being available in a big way, burn-on on relevant position more relevant electronic devices and components, utilize the mode that in kind and figure combines to demonstrate important exemplary electronic circuit.Owing to this kind of demonstrator has the effect amplifying figure and demonstrating visual on book and can directly compare explanation in kind and measure the advantage of each point operating current, it is subject to the welcome of student and teacher.But being disadvantageous in that demonstrator position is fixed, area is less.
Utility model content
This utility model provides a kind of electronic circuit demonstrator, in order to solve defect of the prior art.
This utility model is achieved by the following technical programs:
A kind of electronic circuit demonstrator, it is characterized in that: include base, the both sides of base arrange column, column is offered two chutes, article two, chute respectively front chute and rear chute, front plate body it is equipped with between front chute, between rear chute, rear plate body is set, the top of column arranges directive wheel, being equipped with stay cord on directive wheel, the two ends of stay cord connect the upper end of front plate body and the upper end of rear plate body respectively, and middle part and the bottom of column are respectively provided with fixed block, the hinged retainer ring of sidepiece of front plate body, retainer ring coordinates with fixed block.
A kind of electronic circuit demonstrator as above, described front plate body and rear plate body are plate body, and plate body is offered several uniform screw, screw is equipped with bolt, connecting plate is set between bolt, connecting plate is offered with the through hole corresponding with screw, bolt traverse through hole.
The utility model has the advantages that: this utility model is double; two plate bodys, after using one piece to complete, by drop-down for another block, is risen by new plate body, explains after fixing, and position can convert, and improves the height of explanation plate body, facilitates heel row student viewing to understand.
Accompanying drawing explanation
In order to be illustrated more clearly that this utility model embodiment or technical scheme of the prior art, the accompanying drawing used required in embodiment or description of the prior art will be briefly described below, apparently, accompanying drawing in the following describes is embodiments more of the present utility model, for those of ordinary skill in the art, under the premise not paying creative work, it is also possible to obtain other accompanying drawing according to these accompanying drawings.
