Abstract
The utility model relates to a photoelectric indication teaching rod which comprises a multi-section metal telescopic rod, wherein after contracted, the multi-section metal telescopic rod is arranged in the end section of the metal telescopic rod of which the top end is provided with a luminous diode, and the tail end of the end section of the metal telescopic rod is connected with a handle in which batteries are installed. An electronic watch is installed on the side wall of the upper part of the handle, the tail part of the handle is provided with a small electric bulb, and the outer wall of the handle is provided with a switch. The luminous diode at the top end of the metal telescopic rod is connected with the batteries and the switch by spiral contraction conducting wires, and the switch respectively controls the luminous diode and the small electric bulb to be switched on or be switched off. As the utility model adopts the structure that a luminous element is arranged on the top end of the teaching rod, the pointing direction of the teaching rod can be clear and can be easily identified; at the same time, the teaching rod can attract the attention of students. Because the electronic watch is installed on the handle of the teaching rod, teachers can conveniently master teaching time to control class rhythm. Because the small electric bulb is installed on the tail part of the handle of the teaching rod, the utility model can be used as a minitype electric torch which provides convenience for the illumination of the teachers who go upstairs and downstairs to attend night teaching.
Description
Technical field
The utility model relates to a kind of teacher and uses teaching aid, particularly a kind of photoelectricity indication religion bar.
Background technology
The teacher needs usually with positions such as the literal on the religion bar indication blackboard, numeral, charts when teaching.Conventional religion bar has two kinds: a kind of is wooden or bamboo religion bar.Another kind is a metal religion bar, and metal religion bar adopts telescopic rod-pulling type to teach bar, also has ball pen on the pull bar that has, and is called religion bar pen.The teacher is when the conventional religion of use bar, because religion bar color is close with background color, sensing is fuzzy indeterminate, is difficult for identification.And conventional religion bar can not can not use as miniature flashlight lighting as the electronic watch timing.
The patent that the patent No. is 93224939.6, the utility model name is called multifunctional teaching bar box discloses the teaching aid that a kind of teacher uses.It is with existing pull bar religion bar be screwed one can folding the sidewall of box body on.Can place chalk and curriculum schedule in the box body.Can settle timer and belt buckle on the box body.The teacher teach or scientific and technical personnel when reading out paper, the chalk in available religion bar box is write.After pulling out the religion bar, hand-held box body can be indicated the position of literal on the blackboard or chart, and takes the time with timer.This religion bar box is easy to use, is easy to carry, and can avoid the waste of chalk again and reduce dust pollution, and the time spent is not used for timing and decoration above also can being inserted in penholder, desk lamp etc.
The patent that the patent No. is 94240202.2, the utility model name is called chalk sleeve tube and the integrated teaching aid of flexible religion bar, provide a kind of chalk sleeve and scalable pull bar religion bar integrated teaching aid, be suitable for teacher with chalk and black board teaching, it uses three-pawl type chalk inner sleeve clamping chalk, can regulate the extension of chalk by the spring between inner and outer sleeves, and be combined into one the produced pollution when having avoided direct contact chalk to write with the scalable pull bar religion bar of a band handle.
Summary of the invention
The purpose of this utility model provides a kind of telescopic photoelectricity indication religion bar that luminous indication, electric time-keeping, illumination are one that collects.
To achieve these goals, the utility model comprises: more piece metal expansion link, flexibly connect between the metal expansion link, and more piece metal expansion link shrinks and is placed in the minor details metal expansion link; It is characterized in that: the tip designs of metal expansion link has light emitting diode, and the tail end of minor details metal expansion link is connected with handle; Handle is a cylindrical shape, and battery is housed in it.On the handle upper portion side wall electronic watch is installed, the design of handle afterbody has small electric bulb, and design has switch on the handle outer wall; Small electric bulb is connected with switch with battery by lead; The light emitting diode on metal expansion link top is connected with switch with battery by the screw-pinch lead.
The utility model points to clearly the religion bar and easily recognizes owing in the tip designs of teaching bar light-emitting component is arranged, and can also attract classmates' notice simultaneously.Owing on religion bar handle, electronic watch is installed, can make things convenient for teacher to grasp the class period, control is rhythm on class.Owing to small electric bulb has been installed at religion bar handle afterbody, can be used as miniature electric torch and use, make things convenient for teacher to throw light on when last self-study at night downstairs.
Description of drawings
Figure is a structural representation of the present utility model.
Among the figure: 1, light emitting diode; 2, screw-pinch lead; 3, metal expansion link; 4, minor details metal expansion link; 5, electronic watch; 6, handle; 7, switch; 8, battery; 9, small electric bulb.
Embodiment
The utility model comprises as shown in the figure: more piece metal expansion link 3 flexibly connects between the metal expansion link.Can elongate contraction between the metal expansion link, elongate the back and use, be easy to carry after the contraction as the religion bar.More piece metal expansion link shrinks and is placed in the minor details metal expansion link 4.The tip designs of metal expansion link has light emitting diode 1, and light emitting diode adopts red light emitting diodes.The tail end of minor details metal expansion link 4 is connected with handle 6, and handle 6 is a cylindrical shape, and battery 8 is housed in it, on handle 6 upper portion side wall electronic watch 5 is installed.The design of handle 6 afterbodys has small electric bulb 9, and design has switch 7 on handle 6 outer walls.Small electric bulb 9 is connected with switch 7 with battery 8 by lead.The light emitting diode 1 on metal expansion link top is connected with switch 7 with battery 8 by screw-pinch lead 2.Switch 7 has three control positions, and light emitting diode 1 conducting is luminous when shifting upper end position onto.Small electric bulb 9 conductings were luminous when switch 7 was shifted lower end position onto.Light emitting diode and small electric bulb 9 all cut off the power supply when switch 7 was shifted the centre position onto.
The utility model can use again and can use as miniature electric torch as luminous indication religion bar, also has the electronic watch clocking capability, has reached the multi-functional purpose of a bar.
