Description
Technical field
The utility model relates to mathematical education technical field, specifically relates to a kind of Novel mathematics teaching apparatus.
Background technology
In mathematical education process, relate to the knowledge points such as some mathematics calculation, equilibrium principles.
Utility model content
Technical problem to be solved in the utility model is to provide that a kind of structure is simple, the Novel mathematics teaching apparatus of diverse in function.
For solving the problems of the technologies described above, the utility model provides following technical scheme: a kind of Novel mathematics teaching apparatus, comprise base, the support bar be arranged on base, balance plate, described balance plate is rotationally connected with post upper by bearing pin is dismountable, described balance plate symmetria bilateralis is evenly provided with some columned guide rods, in the middle part of described guide rod and top is provided with external thread part, described guide rod is arranged with some calculation pearls, the external thread part of described guide rod is all threaded limited location sleeve, and described spacing collar external diameter equals balance plate width.
On such scheme basis preferably, described lower end of the guide rod is threadedly connected on balance plate.
On such scheme basis preferably, the horizontal middle position of described balance plate is provided with air-bubble level.
On such scheme basis preferably, described base end face is provided with anti-skid rubber cushion.
The beneficial effect that the utility model compared with prior art has is: wherein, balance plate is rotationally connected with on support bar, balance plate is provided with the guide rod with calculation pearl, being convenient to place same guide rod varying number calculation pearl by regulating, placing different guide rod equivalent amount calculation pearl and demonstrate equilibrium principle; Meanwhile, guide rod is threaded limited location sleeve, is convenient to prevent calculation pearl from coming off from guide rod; Meanwhile, in the middle part of guide rod and top is all threaded limited location sleeve, and spacing collar external diameter equals balance plate width, is convenient to balance plate to pull down and with spacing collar and calculate pearl and combine and uses as abacus, structure simply, diverse in function.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation;
Fig. 2 is the utility model balance plate side view.
Number in the figure is: 1-base, 2-support bar, 3-balance plate, 4-bearing pin, 5-guide rod, 6-spacing collar, and 7-calculates pearl, 8-anti-skid rubber cushion.
Embodiment
In order to make the purpose of this utility model, technical scheme and advantage clearly understand, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the utility model, and be not used in restriction the utility model.
In description of the present utility model, it will be appreciated that, term " longitudinal direction ", " transverse direction ", " on ", D score, " front ", " afterwards ", " left side ", " right side ", " vertically ", " level ", " top ", " end ", " interior ", orientation or the position relationship of the instruction such as " outward " are based on orientation shown in the drawings or position relationship, it is only the utility model for convenience of description, instead of indicate or imply that the device of indication or element must have specific orientation, with specific azimuth configuration and operation, therefore can not be interpreted as restriction of the present utility model.
See figures.1.and.2 known, a kind of Novel mathematics teaching apparatus, comprise base 1, the support bar 2 be arranged on base 1, balance plate 3, described balance plate 3 is rotationally connected with support bar 2 upper end by bearing pin 4 is dismountable, described balance plate 3 symmetria bilateralis is evenly provided with some columned guide rods 5, in the middle part of described guide rod 5 and top is provided with external thread part, described guide rod 5 is arranged with some calculation pearls 7, the external thread part of described guide rod 5 is all threaded limited location sleeve 6, and described spacing collar 6 external diameter equals balance plate 3 width.
Wherein, balance plate 3 is rotationally connected with on support bar 2, and balance plate 3 is provided with the guide rod 5 with calculation pearl 7, being convenient to place same guide rod 5 varying number calculation pearl 7 by regulating, placing different guide rod 5 equivalent amount calculation pearl 7 and demonstrate equilibrium principle; Meanwhile, guide rod 5 is threaded limited location sleeve 6, is convenient to prevent calculation pearl 7 from coming off from guide rod 5; Meanwhile, in the middle part of guide rod 5 and top is all threaded limited location sleeve 6, and spacing collar 6 external diameter equals balance plate 3 width, is convenient to balance plate 3 to pull down and with spacing collar 6 and calculate pearl 7 and combine and use as abacus, structure is simple, diverse in function.
With further reference to Fig. 1, described guide rod 5 lower end is threadedly connected on balance plate 3, and be convenient to realize being separated between guide rod 5 with balance plate 3, applicability is strong.The horizontal middle position of described balance plate 3 is provided with air-bubble level (not shown), is convenient to observe balance plate 3 horizontal equilibrium state.Described base 1 bottom surface is provided with anti-skid rubber cushion 8, is convenient to improve teaching aid non-skid property.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all do within spirit of the present utility model and principle any amendment, equivalent to replace and improvement etc., all should be included within protection domain of the present utility model.
