The top of the telescopic rod is fixedly provided with an indicating lamp. The upper end of the housing is fixedly provided with a laser lamp. An operation board is fixedly arranged on the front of the housing. A master switch, an indicating lamp switch, a laser lamp switch, a PageUp button, a PageDown button, a former step button and a next step button are arranged on the operation board. A storage battery is arranged in the housing. The auxiliary pointer for multimedia teaching has the characteristics of simple structure, abundant functions and practicality.
Description
Technical field
The utility model relates to a kind of teaching aid, especially multimedia teaching apparatus, specifically auxiliary teacher's pointer for multimedia teaching.
Background technology
Along with scientific and technological development, teacher's form of teaching has also not only been confined on blackboard, a lot of courses are due to reasons such as student are many or character calligraph amount is excessive, instructors all utilizes multimedia teaching to solve these problems, but in the process of multimedia teaching, a lot of teachers still indicate the content of courses with the long teacher's pointer of traditional type, and because multimedia board face is larger, the upper end of multimedia board face is difficult to touch with teacher's pointer, therefore some teacher is with the laser pen effect of giving instruction, and laser pen is very easy to rock or tremble in the time of instruction, cause instruction indefinite, teacher is in the time of multimedia, especially science teaching content, relate to wider, many times also need on blackboard, write, and content of multimedia needs to operate by computing machine, operation so repeatedly not only delays instructional blocks of time, also for teacher has increased burden.
Summary of the invention
For addressing the above problem, the utility model proposes a kind of teacher's pointer of simple in structure, feature richness.
Concrete technical scheme is as follows:
Auxiliary teacher's pointer for multimedia teaching, comprise housing and be fixed on the expansion link of housing upper end, described expansion link top is fixed with pilot lamp, housing upper end is fixed with laser lamp, housing front is fixed with operation panel, operation panel is provided with master switch, indicator light switch, laser lamp switch, upper page button, nextpage button, upper step button and lower step button, is provided with accumulator in housing; In described housing, be provided with circuit board, be connected with processing unit on circuit board, described pilot lamp, laser lamp, operation panel and accumulator are connected with circuit board respectively; Described circuit board is provided with transmitter, and transmitter is connected with USB receiver wirelessly, and USB receiver is connected in the USB interface of computer.
The beneficial effects of the utility model: can use as traditional teacher's pointer after expansion link stretches, and top is provided with pilot lamp, during due to employing projector play multimedia, indoor light is all darker, so pilot lamp can better demonstrate the location of content of teacher's indication, and pilot lamp also can be realized with laser lamp, thereby can be with determining indication point in the time of indicator board face upper end, make it be difficult for rocking or trembleing, and for conserve space and easy to use, in indicator board face, can directly realize with laser lamp fixing on housing when hypomere, and according to teacher's needs, be provided with previous step and next step, so that in the time of explanation one page courseware, can explain step by step, also there is the page up of leafing through and lower one page, simple in structure, feature richness and practical.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
In figure: 1-housing, 2-expansion link, 3-pilot lamp, 4-laser lamp, 5-master switch, 6-indicator light switch, 7-laser lamp switch, the upper page of 8-button, 9-nextpage button, the upper step of 10-button, walks button under 11-, 12-accumulator.
Embodiment
Below in conjunction with Fig. 1, the utility model is described in further detail:
Embodiment 1: auxiliary teacher's pointer for multimedia teaching, comprise housing 1 and be fixed on the expansion link 2 of housing 1 upper end, described expansion link 2 tops are fixed with pilot lamp 3, housing 1 upper end is fixed with laser lamp 4, housing 1 front is fixed with operation panel, operation panel is provided with master switch 5, indicator light switch 6, laser lamp switch 7, upper page button 8, nextpage button 9, upper step button 10 and lower step button 11, is provided with accumulator 12 in housing 1; In described housing 1, be provided with circuit board, be connected with processing unit on circuit board, described pilot lamp 3, laser lamp 4, operation panel and accumulator 12 are connected with circuit board respectively; Wherein operation panel can adopt integrated circuit to realize, and is connected with circuit board by soft arranging wire, thereby the each button on operation panel can be connected with circuit board; Described circuit board is provided with transmitter, and transmitter is connected with USB receiver wirelessly, and USB receiver is connected in the USB interface of computer; Its equipment can utilize bluetooth to send and receiving equipment is realized, and its principle is identical with bluetooth mouse, can be according to teacher's needs, on different classrooms, different computing machine, use, and facilitate teacher's teaching.
Wherein: after expansion link 2 stretches, can use as teacher's pointer, and the pilot lamp 3 at its top is connected with circuit board by the wire being provided with in expansion link 2, after unlatching, can play the effect of instruction, and in darker projector classroom, can be distincter express instruction content, and its pilot lamp 3 also can adopt laser class ray type lamp to realize; Laser lamp 4 can be indicated relevant position as required, easy to use; The different key that operation panel is provided with can opertaing device in the work of different device; Accumulator 12 is for store power.
Beneficial effect: simple in structure, feature richness and practical.
