Description
technical field:
the utility model relates to the explanation of a kind of Chinese vocabulary and shows teaching aid.
background technology:
present teacher carries out explaining or writing on blackboard explaining with mouth when explaining Chinese vocabulary, has the writing speed of some students slow when explaining with mouth, remembers the full content that do not get off, is unfavorable for Students ' Learning; If write, blackboard to carry out explain the time in classroom taken too many again, affects teaching process.
summary of the invention:
the purpose of this utility model is to provide one neither to be needed to write on the blackboard, and only neither explain with mouth, both reduce the labour intensity of teacher, also facilitated student and carry out recording and learning, and teaching aid is shown in the Chinese vocabulary explanation that improve learning efficiency.
above-mentioned object is realized by following technical scheme:
teaching aid is shown in a kind of Chinese vocabulary explanation, its composition comprises: base, described base has center hub, described center hub wringing fit inserts bearing, described bearing connects rotating cylindrical, the external toroidal ring of described bearing circumferentially has round jack, the outside of described center hub has concentric jack, described concentric jack is opened on described base, described round jack is connected round bar with the bottom of described concentric jack, described round bar connects W shape elastic plugin, described W shape elastic plugin grafting W shape fixing pluge, described W shape fixing pluge connects round inserted link respectively, described round inserted link wringing fit inserts described round jack respectively with in described concentric jack, connected by circular arc bar between described round inserted link, described rotating cylindrical connects rotary body, described rotary body connects plug-in card frame, described plug-in card frame connects Chinese vocabulary explanation and shows card.
teaching aid is shown in described Chinese vocabulary explanation, described rotary body comprises a base plate, a described base plate connects No. two floors and No. three base plates, No. two described floors are connected No. four base plates with described No. three base plates simultaneously, a described base plate connects a horizontal V-shaped inserted link, No. two described base plates connect No. two horizontal V-shaped inserted links, No. three described base plates connect No. three horizontal V-shaped inserted links, No. four described base plates connect No. four horizontal V-shaped inserted links, described No. one horizontal V-shaped inserted link, described No. two horizontal V-shaped inserted links, described No. three horizontal V-shaped inserted links, described No. four horizontal V-shaped inserted links all connect described rotating cylindrical.
teaching aid is shown in described Chinese vocabulary explanation, and described plug-in card frame comprises end L shape plate, and described end L shape plate connects left L shape plate and right end L shape plate simultaneously, and described Chinese vocabulary explanation shows that the top of card connects half degree of lip-rounding handle.
beneficial effect:
1. the bearing that adopts of the utility model is laborsaving, flexible when rotating cylindrical driven rotary body is rotated, friction force is little.
2. the utility model adopt round jack, with one heart jack, W shape elastic plugin, W shape fixing pluge, justify inserted link, circular arc bar with the use of, make the connection between bearing and base tight, firm, stable, make one-piece construction be in stable state, the effective of card is shown in the Chinese vocabulary explanation of displaying.
3. the base plate that the utility model adopts a horizontal V-shaped inserted link, No. two horizontal V-shaped inserted links, No. three horizontal V-shaped inserted links, No. four horizontal V-shaped inserted links support, No. two floors, No. three base plates, No. four base plates balances, stable; The rotating cylindrical connected is firm, use safety.
4. the utility model adopt end L shape plate, left L shape plate, right end L shape plate with the use of, fixing Chinese vocabulary explanation shows that card is firmly, and bandwagon effect is good, replaces and also facilitates.
accompanying drawing illustrates:
accompanying drawing 1 is the structural representation of this product.
accompanying drawing 2 is structural representations of rotary body in accompanying drawing 1.
