SUMMERY OF THE UTILITY MODEL

The utility model aims at solving the defects of higher manufacturing cost, insufficient image demonstration and inconvenient carrying existing in the prior art and providing a biological teaching aid.

In order to achieve the above purpose, the utility model adopts the following technical scheme:

the utility model provides a biological teaching aid, includes the bottom plate, the surface symmetry of bottom plate is equipped with two colour gamuts, one side of bottom plate surface is rotated and is connected and be equipped with first gear, angles such as first gear are equipped with a plurality of first through holes, one side that first gear was kept away from on the bottom plate surface is rotated and is connected and be equipped with the second gear, the second gear is coupled with first gear, angles such as second gear are equipped with a plurality of second through holes, the fixed surface of bottom plate is equipped with the roof, second gear and first gear are located between roof and the bottom plate, one side on roof surface is equipped with and runs through the groove with the first arc that first through hole is corresponding, one side that first arc runs through the groove is kept away from on the roof surface is equipped with and runs through the groove with the second arc that the second through hole is corresponding, the surface of roof is drawn with the demonstration picture.

Preferably, the colors of the two color gamuts are different.

Preferably, the bottom plate is made of a wood material, and the first gear, the second gear and the top plate are made of a paper material.

Preferably, the first gear and the second gear are both rotationally connected with the bottom plate through drawing pins.

The utility model provides a pair of biological teaching aid, beneficial effect lies in: the utility model discloses the material that adopts is common material in the life, and low in manufacturing cost runs through the mutually supporting between groove, the second arc through groove and the demonstration picture through bottom plate, colour gamut, first gear, first through hole, roof, first arc, can be more vivid and vivid demonstration oxygen and carbon dioxide's transmission principle in blood to the student, the utility model discloses whole comparatively light moderate, the mr of being convenient for carries, and is very convenient.

Drawings

FIG. 1 is a front view of a biological teaching aid provided by the present invention;

fig. 2 is the utility model provides an explosion view of biological teaching aid.

In the figure: the device comprises a bottom plate 1, a color gamut 2, a first gear 3, a first through hole 4, a second gear 5, a second through hole 6, a top plate 7, a first arc-shaped through groove 8, a second arc-shaped through groove 9 and a demonstration chart 10.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments.

Referring to fig. 1-2, a biological teaching aid, including bottom plate 1, the surface symmetry of bottom plate 1 is equipped with two colour gamuts 2, one side on bottom plate 1 surface is rotated and is connected and be equipped with first gear 3, first gear 3 is the angle and is equipped with a plurality of first through-holes 4, one side that first gear 3 was kept away from on bottom plate 1 surface is rotated and is connected and be equipped with second gear 5, second gear 5 and first gear 3 are coupled, second gear 5 is the angle and is equipped with a plurality of second through-holes 6, the fixed surface of bottom plate 1 is equipped with roof 7, second gear 5 and first gear 3 are located between roof 7 and bottom plate 1, one side on roof 7 surface is equipped with the first arc that corresponds with first through-hole 4 and passes through groove 8, one side that first arc passed through groove 8 was kept away from on roof 7 surface is equipped with the second arc that corresponds with second through-hole 6 and passes through groove 9, the surface of roof 7 is drawn and is had.
