Description

A kind of blackboard for teaching device that there is polylith and be capable of transposition
Technical field
The utility model belongs to teaching aid technical field, is related to a kind of teaching use for having polylith and capableing of transposition Blackboard device.
Background technology
It is well known that blackboard be it is essential in our daily teachings as teaching aid, and it is general we usually use Artificial blackboard, writing on erasing blackboard wipe it is not only time-consuming, laborious, but also the shortcomings that have dust pollution air.
Although also have currently on the market can auto-erasing blackboard, it is most of both for one piece of blackboard, wiped When except action, it cannot use, therefore the interruption on course can be caused, use inconvenience.
Utility model content
The utility model provides a kind of blackboard for teaching device for having polylith and capableing of transposition, solves existing When being wiped, course can interrupt automatic blackboard in technology, influence the problem of continuing of teaching, simple in structure, easy to use.
The technical solution of the utility model is:A kind of blackboard for teaching device that there is polylith and be capable of transposition, packet The first blackboard and the second blackboard are included, the motor of the first blackboard and the second blackboard location swap is provided;First blackboard and It is provided with crossbeam between two blackboards, hairbrush is provided on crossbeam, the both ends of crossbeam are both provided with armature, and the both ends of crossbeam are fixed on In first blackboard and the fixed notch of the second blackboard both ends setting;It is provided with spring in fixed notch, electromagnetism is provided in spring Device, calutron are opposite with armature.
Further, the utility model is also characterized by:
Wherein the first blackboard and the second blackboard are setting up and down.
The wherein left and right ends of the first blackboard and the second blackboard are connected by sprocket wheel, and sprocket wheel is connect with motor.
Wherein retarder is additionally provided between motivation and sprocket wheel.
Wherein the first blackboard and the second blackboard are left and right settings.
The wherein upper and lower ends of the first blackboard and the second blackboard are linked by sprocket wheel, and sprocket wheel is linked with motor.
Wherein retarder is provided between motor and sprocket wheel.
The collection device for collecting chalk dust is provided with below its middle cross beam.
Compared with prior art, the utility model has the beneficial effects that:Two pieces of blackboards are used interchangeably, when one piece of blackboard into When row erasing work, another piece of blackboard can continue to carry out course, and the apparatus structure is simple, easy to use, electronic by controlling The location swap of two pieces of blackboards is realized in the direction of the rotation of machine, and by calutron and armature be implemented in combination with crossbeam with it is black Contact between plate, to realize erasing work of the hairbrush to blackboard.
Further, two pieces of blackboards are setting up and down, and so that it is carried out the exchange of upper and lower position by motor, and And by rotation of the retarder with movable sprocket, to make two blackboard location swaps.
With further, two pieces of blackboards are left and right settings, so that it is carried out the exchange of left and right position by motor, and lead to Crossing retarder makes sprocket wheel be smoothly driven, and then drives the location swap of two pieces of blackboards.
Description of the drawings
Fig. 1 is the structural schematic diagram of the utility model;
Fig. 2 is the structural schematic diagram of the utility model middle cross beam.
In figure:1 is the first blackboard;2 be the second blackboard;3 be motor;4 be crossbeam;5 be armature;6 be spring;7 be electricity Magnetic device.
Specific implementation mode
The utility model is described further in the following with reference to the drawings and specific embodiments.
The utility model provides a kind of blackboard for teaching device for having polylith and capableing of transposition, as shown in Figure 1, Including the first blackboard 1 and the second blackboard 2 setting up and down, and the second blackboard 2 is located at behind the first blackboard 1;First blackboard 1 and Two blackboards 2 are connected by sprocket wheel, and sprocket wheel is connect by retarder with motor 3;Motor 3 controls the first blackboard 1 and the Two blackboards, about 2 transposition;The wherein middle position of the first blackboard 1 and the second blackboard 2 is provided with crossbeam 4, under crossbeam 4 Side is provided with hairbrush, and the both ends of crossbeam 4 are both provided with armature 5, and the setting of armature 5 is arranged in the first blackboard 1 and 2 both ends of the second blackboard Fixed notch in, and the length of crossbeam 4 is identical as the length of the first blackboard 1.
As shown in Fig. 2, being provided with calutron 7 in fixed notch, spring 6, calutron 7 are cased with outside calutron 7 It is contacted with armature 5;Upon power-up, calutron 7 adsorbs calutron 7 with 5 phase of armature, and crossbeam 4 is then made to be tightly attached to first On blackboard 1, when the first blackboard 1 is replaced downwards, hairbrush wipes clean the first blackboard 1, while the dress of the collection below crossbeam 4 is arranged It sets chalk ash collection, and the second blackboard 2 is replaced and is used up;First blackboard 1 and 2 transposition of the second blackboard it Afterwards, calutron 7 powers off, and then spring 6 bounces armature 5, makes have certain interval between cross bar 4 and blackboard.
2 left and right settings of the first blackboard 1 and the second blackboard, crossbeam 4 can also be vertically arranged in the utility model Between one blackboard 1 and the second blackboard 2, and sprocket wheel is arranged on the upper and lower position of the first blackboard 1 and the second blackboard 2.
