Description

A kind of teacher's pointer

Technical field

The utility model relates to a kind of teacher's pointer.

Background technology

The teacher's pointer that uses in the school can be divided into mechanical type or electronic type at present, mechanical type, make teacher's pointer with a straight rod or telescopic hollow barred body exactly, its weak point is, specifically where when using this common teacher's pointer indication, the student can only see a fuzzy teacher's pointer profile, be unfavorable for allowing the indicated place of the clear and definite teacher of student, if when light was not very bright, this defective can be more obvious; Electronic type, the light that utilizes light emitting diode or laser instrument to send is exactly indicated, and reaches the purpose of teacher's pointer, is 94216245.4 utility model patent as the patent No., top at teacher's pointer is provided with light-emitting component, its weak point is, because the effect of sunlight, the light of light-emitting component emission is just weakened, it is unclear to thicken, to giving lessons or demonstrating and make troubles, when light was strong, this defective can be more obvious.

The utility model content

No matter the technical problems to be solved in the utility model is to provide a kind of light power at above-mentioned deficiency, teacher's pointer that all can clear indication.

For achieving the above object, the utility model comprises the hollow barred body, be respectively equipped with ceiling light, battery and power switch in hollow barred body top, inside and side, its design feature is: also be provided with lamp bank and flasher at the hollow stick body side surface, portion also is provided with control chip within it, and control chip forms with ceiling light, battery, power switch, lamp bank and flasher and is electrically connected.

As improvement, be provided with catch in the bottom of hollow barred body, can change battery easily.

Principle of work: the power-on switch, battery is given control chip and ceiling light power supply by power switch, and ceiling light begins luminous; Simultaneously, control chip starts operation program, if flasher is in the position of connection, control chip will transmit control signal to lamp bank, and the control lamp bank is according to lighting first lamp 0.1 second the end of to the order on top, after extinguishing 0.1 second, lighted second lamp again 0.1 second, extinguish 0.1 second after, lighted second lamp again 0.1 second, until light last lamp 0.1 second of lamp bank, after extinguishing 0.1 second, lighted last lamp once more 0.1 second, extinguish 0.1 second again after, lighted last lamp once more 0.1 second, this process is an one-period, and first end cycle continues second period, go round and begin again, close or till power switch closes up to flasher.Like this, being exactly one from the utility model on the appearance has the end of to the teacher's pointer of the glittering one by one dynamic deixis in top.

In sum, adopted the teacher's pointer of this structure, had dynamic indicating effect, overcome the defective that the light power causes, and indicating effect has been good, be particularly suitable for giving lessons or demonstrating use.

Description of drawings

Below in conjunction with accompanying drawing the utility model is described in further detail;

Accompanying drawing is the teacher's pointer configuration diagram.

Among the figure: 1 is the hollow barred body, and 2 is ceiling light, and 3 is battery, and 4 is power switch, and 5 is control chip, and 6 is circuit board, and 7 is screw, and 8 is lamp bank, and 9 is flasher, and 10 is catch.

Embodiment
