Compared with prior art, the utility model is convenient to realize quick adjustment, easy to use, easy and simple to handle, saves time, and operating efficiency is high, is applicable to the user of different height, effectively reduces noise simultaneously, and result of use is good.
Accompanying drawing explanation
Fig. 1 is the structural representation at ideological and political education dais.
Fig. 2 is the connection diagram in ideological and political education dais in canyon.
Fig. 3 is the connection diagram of strain pressure transducer in ideological and political education dais.
Detailed description of the invention
Be described in more detail below in conjunction with the technical scheme of detailed description of the invention to this patent.
Refer to Fig. 1-3, a kind of ideological and political education dais, comprise main body 1 and platform slab 2, described main body 1 rear is provided with platform slab 2, main body 1 comprises upper ledge 11 and lower frame 12, wherein lower frame 12 is socketed in inside upper ledge 11, dividing plate 13 is provided with inside upper ledge 11, canyon 14 is provided with above dividing plate 13, be provided with cage 15 below dividing plate 13, in cage 15, be provided with lowering or hoisting gear 3, bottom lowering or hoisting gear 3, be provided with hydraulic cylinder 31, upper ledge 11 sidepiece is provided with lifting controller 32, and lifting controller 32 is electrically connected hydraulic cylinder 31, be provided with lifter 21 bottom platform slab 2, lowering or hoisting gear 3 and lifter 21 regulate jointly, regulate fast, easy to use, are applicable to the user of different height, table top 4 is provided with above described upper ledge 11, table top 4 is provided with Mike 51, loudspeaker 52, power amplifier module 53, controller 54 and power module 55 is provided with in canyon 14, Mike 51 is connected with the input of power amplifier module 53, power amplifier module 53 is connected with controller 54, the output of power amplifier module 53 is connected with loudspeaker 52, and power module 55 is connected with the power end of controller 54, be provided with strain pressure transducer 5 in described canyon 14, strain pressure transducer 5 comprises elastic sensing element, strain ga(u)ge, compensating resistance and shell, and strain pressure transducer 5 is connected with the circuit of power amplifier module 53, the circuit of described power amplifier module 53 is a balanced bridge circuit, is provided with four resistance in balanced bridge, and wherein fixed resistance R2 is equal with fixed resistance R4 resistance, and resistance R1 and resistance R3 is variable resistor, and resistance R3 is the compensating resistance of strain pressure sensor 5, described balanced bridge comprises two output C, D and two offset side A, B, and offset side A, B connect power module 55 and controller 54, output C, wired power amplifier module 53 and the electromagnetic relay for controlling power amplifier module 53 connecting and disconnecting of the circuit between D, during use, by the circuit communication of power amplifier module 53, now because electric bridge is in poised state, C, the voltage that D exports is zero, electromagnetic relay 4 is in normally off, power amplifier module 53 normally works, when canyon 14 is elevated, main body 1 vibrates the elastic sensing element touching strain pressure transducer 5, compensating resistance changes and causes electric bridge unbalance, C, D holds output voltage, electromagnetic relay is energized disconnect, now power amplifier module 53 is closed and is postponed a period of time, until canyon 14 no longer vibrates, electromagnetic relay closes, power amplifier module 53 is resumed work, effectively prevent canyon lifting and produce noise.
Above the better embodiment of this patent is explained in detail, but this patent is not limited to above-mentioned embodiment, in the ken that one skilled in the relevant art possesses, various change can also be made under the prerequisite not departing from this patent aim.
