In figure: 1 handle, 2 flagellations, 3 batteries, 4 button switches, 5 potential devices, 6 rubber sleeves, 7 conductive sheets, 8 ER fluids Filled layer, 9 counterweights, 10 corrugated surfaces, 11 limit holes, 12 lanyards, 13 battery cases, 14 battery case lids.

Specific embodiment

Following will be combined with the drawings in the embodiments of the present invention, and technical solution in the embodiment of the present invention carries out clear, complete Site preparation description, it is clear that described embodiments are only a part of the embodiments of the present invention, instead of all the embodiments.

Referring to Fig.1-2, a kind of multimedia teaching ancillary equipment, including handle 1,1 one end of handle are connected with flagellation 2, hand Battery case 13 is offered in handle 1, battery 3 is placed in battery case 13, and 1 end of handle is rotatably connected to battery case lid 14, battery 14 closing battery box 13 of box cover, after prolonged use, when 3 electric quantity consumption of battery is complete, openable battery case lid 14 is convenient The battery 3 more renewed guarantees to work normally.

Battery 3 is electrically connected with button switch 4, and battery 3 and button switch 4 are electrically connected 5 input terminal of potential device, press Button switch 4 is mounted on 1 outer surface of handle, and button switch 4 plays the role of control circuit on-off in entire circuit.

Button switch 4 is electrically connected with potential device 5, and the potential device 5 is mounted in handle 1, exports to battery 3 Voltage boosts, and to 7 output HIGH voltage of conductive sheet after having boosted, makes ER fluid filled layer to provide enough electric field strengths 8 generation liquid are converted admittedly.

Flagellation 2 includes rubber sleeve 6, conductive sheet 7 and ER fluid filled layer 8, the filling of 6 sealed envelope ER fluid of rubber sleeve Layer 8, ER fluid filled layer 8 is made of ER fluid, and ER fluid is a kind of suspension at typical condition, by with Gao Jie The solia particle of electric constant, which is dispersed in the insulating oil of low-k, to be formed, and liquid can occurs in it under the action of electric field To solid transformation, when electric field strength is significantly less than some critical value, ER fluid is in a liquid state；When electric field strength significantly When higher than this critical value, it reforms into solid-state.

6 inner cavity two sides of rubber sleeve are fixedly connected with two conductive sheets 7, and two conductive sheets 7 are electric respectively far from 6 side of rubber sleeve Property connects and sticks on 8 two sides of ER fluid filled layer, and two 7 one end of conductive sheet are electrically connected with 5 output end of potential device.

1 peripheral side of handle offers corrugated surface 10 and limit hole 11, and 10 peripheral side of corrugated surface is wound with flagellation 2 or the hand that reclines The palm, 11 clearance fit flagellation of limit hole, 2 top.

When not in use, ER fluid filled layer 8 is in a liquid state, and wind flagellation 2 in soft condition, can integrally by flagellation 2 It is inserted into limit hole 11, is fixed on the corrugated surface 10 on handle 1, and by 2 end of flagellation, greatly reduce teaching and use The length of whip facilitates carry-on transportation.

Handle 1 is fixedly connected with lanyard 12 far from 2 one end of flagellation, conveniently hangs on hand, prevents this hair in use It is bright to be slid from hand, it avoids falling hitting and causes to damage on the ground.

Far from counterweight 9 is fixedly connected in the top of 1 one end of handle, counterweight 9 is completely encapsulated in rubber sleeve 6 for flagellation 2 Portion, assist handle 1 and flagellation 2 naturally droop, and improve the texture in use process.

When in use, flagellation 2 is opened, handle 1 is held, naturally droops handle 1 and flagellation 2, press button switch 4, this When circuit be connected, 3 output voltage of battery by potential device 5 boost after, by conductive sheet 7 to ER fluid filled layer 8 apply Some strength electric field force, ER fluid are influenced by electric field force, are changed from liquid to solid, so that soft flagellation 2 be made to become to endure It is straight and firm, it is convenient that teaching instruction is carried out to PPT teaching notes.

Now operating principle of the invention is done described below:

Firstly, when not in use, ER fluid filled layer 8 is in a liquid state, make flagellation 2 integrally in soft condition, it can be by flagellation 2 It is wrapped on the corrugated surface 10 on handle 1, and 2 end of flagellation is inserted into limit hole 11, be fixed, greatly reduce religion The length for using whip is learned, carry-on transportation is facilitated.

And when in use, flagellation 2 is opened, handle 1 is held, the auxiliary for the counterweight 9 being fixedly connected in 2 top of flagellation Under, handle 1 and flagellation 2 naturally droop, and improve the texture in use process, press button switch 4, and circuit is connected at this time, electricity After 3 output voltage of pond is boosted by potential device 5, some strength electric field is applied to ER fluid filled layer 8 by conductive sheet 7 Power, ER fluid are influenced by electric field force, are changed from liquid to solid, so that soft flagellation is made to become straight and upright and firm, it is convenient Teaching instruction is carried out to PPT teaching notes.

The foregoing is only a preferred embodiment of the present invention, but scope of protection of the present invention is not limited thereto, Anyone skilled in the art in the technical scope disclosed by the present invention, according to the technique and scheme of the present invention and its Inventive concept is subject to equivalent substitution or change, should be covered by the protection scope of the present invention.
