Embodiment

By describing technology contents of the present utility model, structural attitude in detail, realized object and effect, accompanying drawing is coordinated to be explained in detail below in conjunction with embodiment.

Refer to Fig. 1 to Fig. 3, the utility model provides the state retaining device being applied to Internet of Things, comprise processor, processor respectively with the base stage of the first PNP triode Q1, the base stage of the second PNP triode Q2, the base stage of the one NPN triode Q3, the base stage of the 2nd NPN triode Q4 connects, the emitter of the first PNP triode, the emitter of the second PNP triode is connected with positive source, the collector of the first PNP triode is connected with the collector of a NPN triode and the one end controlling motor, the collector of the second PNP triode is connected with the collector of the 2nd NPN triode and the other end controlling motor, the emitter of the one NPN triode, the emitter of the 2nd NPN triode is connected with power cathode, also comprise fixed support 1, control motor and to be arranged on fixed support 2, control motor and can select 5V direct current generator, control motor 2 and there is rotation axis, one end of rotation axis is connected with rotary disk 3, both sides, rotary disk side are respectively arranged with contact flat spring 4, contact flat spring is communicated with by wire 5, fixed support is also provided with junction block 7, in the middle of junction block, there is cylindrical hole 8, the diameter of cylindrical hole is greater than rotary disk, cylindrical hole is set in rotary disk periphery and is in same axis with rotary disk, the both sides of the sidewall of cylindrical hole are respectively arranged with the first conductor piece 9 and the second conductor piece 10, first conductor piece and the second conductor piece insulate, first conductor piece is connected with the first binding post 11, second conductor piece is connected with the second binding post 12, rotary disk bottom surface is connected with gag lever post 13, junction block sidewall is provided with the first limited post 14 and the second limited post 15, when gag lever post contacts with the first limited post, the contact flat spring of rotary disk both sides contacts with the second conductor piece with the first conductor piece respectively, when gag lever post contacts with the second limited post, the contact flat spring of rotary disk both sides contacts with the second conductor piece with the first conductor piece time different.

Processor of the present utility model can be CPU or single-chip microcomputer etc., processor can control the level state of the base stage of each triode, as controlled triode Q1 and Q4 conducting, Q2 and Q3 closes, the rotating forward controlling motor can be realized, and realizing controlling triode Q1 and Q4 closedown, namely Q2 and Q3 conducting can realize the reversion controlling motor, namely can realize the control to controlling motor positive and inverse by processor and triode.The utility model in use, first controls motor and rotates clockwise (can be rotate forward), after electric machine rotation, drive gag lever post motion, when gag lever post moves to the first limited post, stop.Now the state of contact flat spring can be as shown in Figure 3, contact flat spring contacts with the second conductor piece with the first conductor piece respectively, and the first conductor piece is communicated with the second conductor piece with wire by contact flat spring, in motor power-off or when having a power failure, motor keeps motionless, then keep conducting state.When needing the conducting state of shut-off circuit, only need to control motor to rotate counterclockwise, gag lever post can move to the second limited post, rotary disk stops, now contact flat spring is in up/down state, and namely contact flat spring does not contact with conductor piece, makes the first conductor piece and the second conductor piece not conducting, now motor power-off or power failure, this electric-controlled switch can keep closed condition.Wherein, the elastic force of contact flat spring contributes to the contact of contact flat spring and conductor piece.

The foregoing is only embodiment of the present utility model; not thereby scope of patent protection of the present utility model is limited; every utilize the utility model instructions and accompanying drawing content to do equivalent structure or equivalent flow process conversion; or be directly or indirectly used in other relevant technical fields, be all in like manner included in scope of patent protection of the present utility model.
