Specific embodiment
Below in conjunction with attached drawing, a preferred embodiment of the present invention will be described in detail.
Such as Fig. 1~3, a kind of multifunctional teaching rod, including up-small and down-big nunchakus body 1 in a circular table shape, 1 lower outside of nunchakus body
It is connected with wireless microphone 2, it is taking portion 3 that nunchakus body 1, which is located at 2 upper section of wireless microphone, and nunchakus body center upper portion is equipped with infrared shot-light
4, RF RF remote 5 and blackboard eraser turnover mechanism are equipped in the middle part of nunchakus body 1；The taking portion 3 is equipped with infrared shot-light 4 electrically
The irradiation button 6 of its on-off is connected and controlled, and is electrically connected with RF RF remote 5 and wirelessly controls on computer
The page-turning button 7 of the free page turning of lantern slide.
It is taking portion 3 since nunchakus body 1 is located at 2 upper section of wireless microphone, and when teachers, it holds in taking portion 3, takes
Religion rod when being directed toward blackboard, be just direction of the lower part to Student Teachers of nunchakus body 1, the more convenient religion of position setting of wireless microphone 2
Teacher says the radio reception of class hour, while also solving the problems, such as to be equipped with simultaneously when teachers and teaching rod and loudspeaker, practicability higher.
In the present embodiment, power supply, the on-off control of wireless microphone 2, and the wireless connection with religion room sounding, it is the existing of maturation
Technology, therefore the application does not repeat them here.
Since irradiation button 6 is set in taking portion 3, teachers' instruction process middle finger is also facilitated to press connection infrared
Shot-light 4, and then realize that the expression to emphasis knowledge point on blackboard or projection screen indicates.Equally, the power supply of infrared shot-light 4 and
Circuit connection is the mature prior art, therefore the application does not repeat them here.
Equally, page-turning button 7 is also disposed in taking portion 3, therefore teachers' instruction process middle finger is also facilitated to press progress
Signal interaction is completed with RF RF remote 5 afterwards, RF RF remote 5 is used as signal transmitting terminal, then receives with the USB on computer
Interaction is completed at end, realizes the automatic page turning of PPT on projection screen.
The blackboard eraser turnover mechanism includes sliding block 8, transmission rope 9, fixed pulley 10, blackboard eraser pedestal 11, blackboard eraser 12, turns
Axis 13 and torsional spring 14；The blackboard eraser 12 is set on blackboard eraser pedestal 11；The blackboard eraser pedestal 11 can be turned by shaft 13
It is dynamic to be set to 1 thickness direction of nunchakus body；The shaft 13 is vertically arranged, and both ends are connected with torsional spring 14；14 both ends of torsional spring
It is connected to nunchakus body 1 and blackboard eraser pedestal 11；The sliding block 8 is vertically slidably set to 1 surface of nunchakus body, can specifically pass through cunning
Slot structure clamps setting；The fixed pulley 10 is arranged in nunchakus body 1；9 both ends of transmission rope are connected to blackboard eraser pedestal
11 and sliding block 8, and transmission rope 9 is vertical connect with blackboard eraser pedestal 11.
When sliding block 8 is located at limes superiors position, that is, be located at sliding slot the top when, blackboard eraser pedestal 11 with respect to nunchakus body 1 outwardly, and
Blackboard eraser pedestal 11 is matched with the round table-like outer phenotype face of nunchakus body 1, and inwardly with respect to nunchakus body, torsional spring 14 is in certainly blackboard eraser 12 at this time
Right non-energy storage state.
When sliding block 8 is located at limit inferior position due to external force, specific can be finds occur writing on the blackboard mistake on blackboard in teacher
Accidentally, and at clerical error when blackboard is higher by, teacher can pull downward on sliding block 8 with thumb, and sliding block is made to be located at sliding slot
Bottom, in conjunction with Fig. 2,3 understand, under the action of fixed pulley 10, transmission rope 9 movement from vertically become laterally, and transmission rope 9 with
Blackboard eraser pedestal 11 is vertically to connect, therefore under the draw of transmission rope 9, overcoming 14 active force of torsional spring, (torsional spring 14 is in
Energy storage state), 13 rotations realize opposite nunchakus body 1 inwardly to blackboard eraser pedestal 11 around the shaft, and blackboard eraser 12 is outwardly with respect to nunchakus body 1 at this time
(attached that the state is not shown in the figure, but should be readily appreciated that), teacher holds religion roller at this time, completes wrong plate using the blackboard eraser 12 produced
The erasing of book, finally, unclamping sliding block 8, in the case where the release of the active force of 14 energy storage of torsional spring, sliding block 8 automatically resets to pole
Limit, blackboard eraser pedestal 11 go back to opposite nunchakus body 1 side outwardly around the shaft, and blackboard eraser 12 goes back to opposite nunchakus body 1 side inwardly, extensive
The receiving state of multiple blackboard eraser 12.
Such as Fig. 2,4, further, the present embodiment further includes that the line change for being located at infrared 4 top of shot-light at the top of nunchakus body 1 is arranged in
Mechanism；The Xian Bian mechanism includes the folding anti-dazzling screen 15 that two panels is oppositely arranged, and every 15 one end of anti-dazzling screen is connected to rod
Body 1, the other end are connected to an operating stick 16.The main purpose of Xian Bian mechanism is to realize that infrared shot-light 4 irradiates the finger come
Show that light can be transformed into line by point, facilitates and the lower section of text a bit of on blackboard or projection screen is formed into indicateing arm to student
Know.Be specifically identified the length of line and thickness can by two operating sticks 16 further with it is separate, adjustment two panels foldable
The distance between anti-dazzling screen 15 realizes that is, distance is closer, and tag line is about elongated, and distance is remoter, and tag line gets over tubbiness.It needs
Bright, operating stick 16 can be moved smoothly in 1 upper face of nunchakus body, and the mode specifically steadily realized can be operating stick
16 be to have certain magnetic connection with 1 upper face of nunchakus body, that is, facilitates operating stick 16 in the sliding of 1 upper face of nunchakus body, also just
Just the positioning of stopping at any time after operation of teacher.
Further, in the present embodiment, the inner concave to match with finger palm type face is offered in taking portion 3；It is described
Inner concave includes four finger portions 31 and great thenar portion 32, which can comply fully with stress condition when palm taking religion rod, make to teach
Rod is obtained more steady by taking.
Further, in the present embodiment, inner concave appearance lays one layer of frosted layer, skidding when can prevent from holding writing.
Further, in the present embodiment, sliding block 8 is located at 1 surface of nunchakus body of 32 top of great thenar portion, it can be appreciated that manpower
Palm thumb is located in the top of great thenar portion 32, therefore the design can facilitate teacher's thumb to pull downward on sliding block 8 with will be black
Blackboard eraser 12 produces use.
Further, it is located to be equipped with below blackboard eraser 12 in the present embodiment, in nunchakus body 1 and collects grey drawer 17, collects grey drawer 17
It can unify to collect the subsequent chalk dust fallen of blackboard eraser 12, then whole extract out after the grey drawer 17 of collection is toppled over continues to put back to use,
Avoiding the problem that excessive chalk dust from being deposited in inside nunchakus body 1 causes equipment fault and inconvenience to clean out appearance.
Finally, it is stated that preferred embodiment above is only used to illustrate the technical scheme of the present invention and not to limit it, although logical
It crosses above preferred embodiment the present invention is described in detail, however, those skilled in the art should understand that, can be
Various changes are made to it in form and in details, without departing from claims of the present invention limited range.
