Abstract
The utility model discloses a rotary light band dynamic geography teaching device, comprising a geography graphic board. The geography graphic board is provided with a marking shape window, the position corresponding to the marking shape window behind the geography graphic board is provided with a rotary table, the rotary table is provided with a light band; a marking shape window with directivity is provided on the marking shape board of the teaching device, a rotary light band is provided behind the window, the aim of dynamic demonstration is realized through persistence of users' vision, the utility model has a strong dynamic sense and a good effect.
Description
The utility model relates to a kind of geographical teaching instrument.
In the prior art, in the dynamic demonstration instrument of spontaneous phenomenons such as the cold front of geographical teaching, the warm front, monsoon, water cycle, cyclone, anticyclone, all use led technology, by the luminous dynamic effect that causes of beating of light emitting diode.The shortcoming of this type of device is: 1 light emitting diode is the great-jump-forward flicker, makes people's dim eyesight, is not easy to observe, and teaching efficiency is poor; 2 light emitting diodes need be done again from the beginning after finishing one-period, lack continuity; 3 motions are lacked unity and coherence.
The purpose of this utility model is: provide a kind of rotation light belt dynamic geographical teaching appliance, this teaching appliance is offered the marking shape window with directivity on geographical chart board, in the window back rotation light belt is set, utilize people's persistence of vision, reach the purpose of dynamic demonstration, dynamic strong, effective.
The technical solution of the utility model is: the dynamic geographical teaching appliance of a kind of rotation light belt, comprise geographical chart board, and offer marking shape window on the described geographical chart board, the position corresponding to marking shape window behind geographical chart board is provided with rotating disk, and rotating disk is provided with light belt.
One of technical scheme that the utility model is detailed is: the dynamic geographical teaching appliance of a kind of rotation light belt, comprise geographical chart board, and offer marking shape window on the described geographical chart board, the position corresponding to marking shape window behind geographical chart board is provided with rotating disk, and rotating disk is provided with light belt; Described marking shape window is curved, and is provided with the arrow of expression direction, and described light belt is the arc opposite with marking shape window by the outside scattering in the center of circle of rotating disk; This scheme is used for monsoon active presentation instrument.
Two of the technical scheme that the utility model is detailed is: the dynamic geographical teaching appliance of a kind of rotation light belt, comprise geographical chart board, and offer marking shape window on the described geographical chart board, the position corresponding to marking shape window behind geographical chart board is provided with rotating disk, and rotating disk is provided with light belt; Described marking shape window linearly, and be provided with the expression direction arrow, described light belt is the rectilinear form from the outside scattering in the center of circle of rotating disk; This scheme is used for water cycle active presentation instrument.
The utility model has the advantages that:
1. the utility model is offered the marking shape window with directivity on geographical chart board, in the window back rotation light belt is set, and utilizes people's persistence of vision, reaches the purpose of dynamic demonstration, and is dynamic strong, effective.
2. the utility model does not jump and scintillation, helps student's observation, and the continuity of light belt is good, and is uninterrupted, the motion parts clear layer.
The utility model will be further described below in conjunction with drawings and Examples:
Fig. 1 is the structural representation of embodiment one;
Fig. 2 is the structural representation of embodiment two;
Fig. 3 is the side structure synoptic diagram;
Wherein: 1 geographical chart board; 2 marking shape windows; 3 rotating disks; 4 light belts; 5 motors.
Embodiment one: as Fig. 1, shown in Figure 3, the dynamic geographical teaching appliance of a kind of rotation light belt comprises geographical chart board [1], offers marking shape window [2] on the described geographical chart board [1], position in geographical chart board [1] back corresponding to marking shape window [2] is provided with rotating disk [3], and rotating disk [3] is provided with light belt [4]; Described marking shape window [2] is curved, and is provided with the arrow of expression direction, and described light belt [4] is and the opposite arc of marking shape window [2] by the outside scattering in the center of circle of rotating disk [3]; This embodiment is a monsoon active presentation instrument.
Embodiment two: as Fig. 2, shown in Figure 3, the dynamic geographical teaching appliance of a kind of rotation light belt comprises geographical chart board [1], offers marking shape window [2] on the described geographical chart board [1], position in geographical chart board [1] back corresponding to marking shape window [2] is provided with rotating disk [3], and rotating disk [3] is provided with light belt [4]; Described marking shape window [2] linearly, and be provided with the expression direction arrow, described light belt [4] is the rectilinear form from the outside scattering in the center of circle of rotating disk [3]; This embodiment is used for water cycle active presentation instrument.
In the actual fabrication process, what marking shape window [2] can be empty in detail also can be transparent, and rotating disk [3] can drive with small machine [5], and light belt [4] is the colour band that is indicated on the rotating disk [3], can make different shape as required.
