Abstract

The utility model belongs to the field of training aids and particularly relates to a history training aid. The history training aid comprises a rectangular framework and a supporting rod; the supporting rod which is arranged under the framework is flexibly connected with the lower portion of the framework; a circular base is arranged under the supporting rod; the supporting rod is arranged at a central position on the lower portion of the framework; a plurality of double-layer boxes are arranged inside the framework; circular holes are formed in central positions on lower portions of the boxes; a longitudinal rotary shaft penetrates the circular holes to be connected with the upper portion and the lower portion of the framework; outward sides of the boxes are provided with transparent view windows; the interior thickness of every layer of boxes is from 1 to 4 mm. According to the history training aid, when a teacher teaches various history knowledge, pictures which show history events are arranged inside the boxes inside the training aid, or character relation charts and event relationship graphs of the history events are arranged inside the boxes, then students can absorb various history knowledge, learning interests are increased, and the learning efficiency is improved.

Description

A kind of history teaching aid

Technical field

The utility model belongs to teaching aid field, is specifically related to a kind of history teaching aid.

Background technology

?student is in the time of studying history knowledge at present, get used to listening teacher to say, or oneself reads various historical books, to reach the object of memory, this memory style is more uninteresting, and student also easily forgets in learning process, for dullness uninteresting various historical knowledges again, the rigid memory of students will inevitably cause remembering easily also to forget soon, the time of memorize mechanicalling has been grown, will forget various knowledge, be unfavorable for further learning from now on, therefore need improve for above-mentioned mode of learning, design a kind of interesting, the history teaching aid of picture and text combination, allow the various historical knowledges of the more deep understanding of student, more firmly grasp various knowledge.

Summary of the invention

For solving the problems of the technologies described above, the utility model provides a kind of history teaching aid relatively lively, that various pictures can be provided in teaching process.

History teaching aid of the present utility model is realized by following technical proposals:

A kind of history teaching aid, the support bar that this teaching aid comprises rectangular framework and is positioned at framework below and is flexibly connected with framework bottom, there is cup dolly support bar below, support bar is positioned at the center position of framework bottom, there is the double-layer box of multiple tops band opening framework inside, and there is circular hole the lower central position of box body, and longitudinal rotating shaft is connected with the upper and lower of framework through circular hole, box body one side outwardly has transparent window, and the thickness of every layer of box body inside is 1-5mm.

Above-mentioned base is threaded with bracing frame, and bracing frame is threaded with framework.

Above-mentioned transparent window is glass or organic glass.

The thickness at above-mentioned box opening place is 2mm.

Above-mentioned double-layer box has upper and lower two groups, lays respectively at the first half and Lower Half in framework, in actual use, multibilayer box body also can be set as required.

Between two groups of above-mentioned box bodys, there is pin, this pin is fixedly connected with rotating shaft, the two ends of pin are fixedly connected with the framework of left-hand component and right-hand component respectively, between top box body and pin, there is rubber washer, between box body on the lower and framework, there is rubber washer, two above-mentioned rubber washers can ensure that box body maintains a certain distance with pin when rotated, smoothly rotation.

Above-mentioned framework is wood material, and rotating shaft is stainless steel material, and bracing frame is wood material, and base is stainless steel material.

The left-half of box body and right half part about rotating shaft axisymmetricly, the 5/7-6/7 of the width that the width of box body is framework.

The height of framework and the height ratio of bracing frame are 1:2-3.

The beneficial effects of the utility model are, adopt the history teaching aid of said structure, teacher is in the time lecturing various historical knowledge, the picture of reaction historical events can be placed in to the box body of above-mentioned teaching aid, or the character relation table of historical events, event relation figure are placed in box body, allow student absorb various historical knowledges, to strengthen the interest of study, improve learning efficiency.
