Abstract

The utility model relates to an automatic chalk pen with a function of remote pointing patterns and words. The utility model can automatically retract, extend out and hold a chalk for writing on a blackboard by a teacher; the cavity body of the side part of an outer tube (2) of the chalk pen or the cavity body of one end of a trifurcate inner tube (1) of the chalk pen is provided with an illuminator (6), a battery (9), a switch (7) used for controlling power on and off and a conducting wire (8) used for connecting the illuminator (6), the battery (9) and the switch (7) to a loop, wherein the front end of the illuminator (6) is also provided with a light collecting piece (5) used for collecting scattering light into a light column, and the illuminator (6) and the light collecting piece (5) jointly form a light spot launching apparatus. Thus, the utility model also has the function of pointing the patterns and words on the blackboard or a screen at a long distance; the utility model is an ideal teaching tool with double functions of the chalk pen and a teaching tool.

Description

Has the Automatic chalk holder of pointing in the direction of the picture and text function

Technical field

Have the Automatic chalk holder of pointing in the direction of the picture and text function and be and a kind ofly can either take in, stretch out and clamp chalk automatically and write, can penetrate luminous point again, can be used as religion and hold in both hands and equally give directions on the blackboard or the chalk pen of picture and text on the screen, belong to improved chalk pen.

Background technology

Have before the Automatic chalk holder invention of pointing in the direction of the picture and text function, the teacher on class, use chalk pen and two kinds of teaching aids of religion rod, the problem that they have much room for improvement below existing: (1) chalk function singleness, as the patent No. is ZL01253293.2 " Automatic chalk holder ", manages in the trident by outer tube and storage dress chalk and forms, and relies on the effect of a spring, make chalk take in, stretch out and clamp chalk, only write for the teacher; (2) the religion rod is too short, common one draws religion rod that bamboo and wood, metal bar or telescopic metal tube make, its long 2-3 chi of not crossing, make many teaching lively, excellent in voice and affection, like the dais is used as in whole classroom, teacher between sub-student's desk shuttles back and forth while giving a lecture, when he need do more excellent speech in conjunction with the picture and text on the blackboard, directly exhale the religion rod too short, beyond one's ability to help; (3) chalk pen and religion rod are two independently teaching aids, make the teacher who moves towards the classroom hurriedly often forget one and influence teaching efficiency.

Summary of the invention

The purpose of this utility model is to provide a kind of Automatic chalk holder of pointing in the direction of the picture and text function that has.The technical scheme of this utility model is to realize like this, the interior pipe of trident that it has outer tube and is placed in one, place a spring in the gap that interior all boss of the periphery convex shoulder of pipe and outer tube form in trident, it is characterized in that, in the cavity of outer tube side connection, installation by photophore, for the battery of photophore power supply, connect the lead that their become closed-loop path, control switching with a switch in the loop, be provided with a collective optics at the front end of photophore in addition and constituted the device that can launch luminous point jointly; The technical scheme of this utility model also can realize like this, the interior pipe of trident that it has outer tube and is placed in one, place a spring in the gap that interior all boss of the periphery convex shoulder of pipe and outer tube form in trident, it is characterized in that, in trident in the cavity of Guan Yiduan, installation by photophore, for the battery of photophore power supply, connect the lead that their become closed-loop path, control switching with a switch in the loop, in addition, be provided with a collective optics at the front end of photophore and constituted the device that to launch luminous point jointly.Wherein said photophore, can be with common indicator lamp, electroluminescent diode, electroluminescent semiconductor, more can electricity consumption cause laser hole drilling illuminator, allly can produce arbitrary color such as red, yellow, green in the visible spectrum by electroluminescent ... etc. various light, all be suitable for; Power switch is contact witch, reed switch, the various switches that can control electric switching such as contact switch; Battery can be with button cell or cylindrical battery or cylindricality chargeable battery; Lead is a common wiring, or copper, aluminum metal book sheet, and its cavity just can serve as the lead effect if cavity is made then with metal, with photophore and battery formation closed-loop path; Collective optics is concavees lens or convex lens, or the lens that one side is protruding, one side is recessed, is arranged on the front end of photophore, and the light that the light of dispersing that photophore is penetrated becomes boundling penetrates, and the collective optics useable glass is made, also available transparent plastic manufacturing.Owing to adopted technique scheme, the utility model obviously has the following advantages: (1), chalk pen and two teaching aids of religion rod are united two into one, and write and give advice function and have concurrently; (2), penetrate luminous point and can give directions pattern, literal at a distance, the teacher can give directions the lecture contents of knowing on the blackboard (or other screen) in the optional position at any time in the classroom; (3), easy to carry.

Description of drawings

Have the Automatic chalk holder of pointing in the direction of the picture and text function following three width of cloth accompanying drawings are provided.

Fig. 1, be the Automatic chalk holder of pointing in the direction of the picture and text function that has that emission luminous point device is housed in the cavity of outer tube side connection.

Fig. 2, be the Automatic chalk holder of pointing in the direction of the picture and text function that has that emission luminous point device is housed in the cavity of Guan Yiduan in trident.

Fig. 3, be the electrical schematic diagram of photophore.

The specific embodiment

Details are as follows to have the Automatic chalk holder embodiment of pointing in the direction of the picture and text function:

Fig. 1, Fig. 2, in, pipe (1) places outer tube (2) in the trident, in the gap that all boss form in pipe (1) periphery convex shoulder and the outer tube (2) in trident, establishes a spring (3), manages in (1) cavity clamping in the trident and piece of chalk (4).At Fig. 1, in the cavity of outer tube (2) side connection, or manage in (1) upper chamber in the trident of Fig. 2, be equipped with respectively by photophore (6), battery (9), with a lead (8) with photophore (6) and battery (9), be connected into a loop, switch in the loop (7) control break-make (electric wiring is consulted Fig. 3) is provided with a collective optics (5) at the front end of photophore (6) and has constituted the device that can launch luminous point jointly.

If cavity metal manufacturing, then this metallic cavity can be served as lead (8) battery (9) photophore (6), switch (7) are constituted the loop jointly.

So above-mentioned combined unit is exactly to have the Automatic chalk holder of pointing in the direction of the picture and text function.
