The invention relates to a gear lock mechanism with an anti-theft device. The gear lock mechanism comprises a lock body and a lock tongue pulling plate, the position, below the lock tongue pulling plate, inside the lock body is provided with a driving gear and a driven gear, the driving gear is composed of an upper layer and a lower layer, the upper layer is a tooth ring, the lower layer is a linkage loop, the driving gear is provided with an insert connection slot in the axial direction, a lock core drives the driving gear to rotate through the linkage loop, the tooth ring is engaged with thedriven gear, the driven gear is eccentrically provided with two pin holes, the lock tongue pulling plate is provided with a transmission slot, a positioning seat is arranged above the lock tongue pulling plate, two eccentric pins on the positioning seat penetrate through the transmission slot and are fixedly connected with the two pin holes, the eccentric pins are in transmission coordination with the transmission slot, the lock body is internally and slidably provided with an anti-theft piece, an end portion embossment of the anti-theft piece is matched with a lock core installation hole inthe lock body, the anti-theft piece is driven by a shifting piece hinged inside the lock body, and the shifting piece bears the pressure of a torsional spring. According to the gear lock mechanism with the anti-theft device, by means of the above-mentioned design, the gear lock mechanism with the anti-theft device has the advantages of being compact in structural design, convenient and flexible tooperate and use, strong in anti-theft performance, high in reliability and long in service life.

The invention relates to a gear drive mechanism of a door lock. The gear drive mechanism of the door lock comprises a lock body and a lock tongue pulling plate in the lock body. A gearbox is fixed to the bottom of the lock body, and a driving gear, two intermediate gears and a driven gear are arranged in the gearbox. The driving gear is composed of an upper layer and a lower layer, the upper layer is a linkage ring, and the lower layer is a gear ring. An inserting groove matched with installation of a lock cylinder is formed in the driving gear in the axial direction, and the inserted lock cylinder drives the driving gear to rotate through the linkage ring. The gear ring of the driving gear are engaged with the two intermediate gears which are engaged with the driven gear, and two eccentric pins are fixed to the upper end of the driven gear in the axial direction and matched with transmission grooves formed in the lock tongue pulling plate. Through the specific design of the gear drive mechanism, the gears in the lock body operate in the gearbox, so that operation stability is greatly improved; and the gear drive mechanism has the advantages of being convenient and flexible to operate and use, high in reliability and long in service life.

The invention discloses an azimuth angle / radial adjustable vortex wave receiving antenna bracket, wherein the bracket comprises straight arms, a disc and a tripod; the number N of the straight arms islarger than or equal to 2, wherein an antenna fixing groove and an adjusting groove are formed in each straight arm; two adjusting metal rods penetrate through the adjusting grooves and are used foradjusting the radial distance; a first annular groove, a second annular groove and a third annular groove are formed outwards in sequence by taking the center of the disc as the original point, wherein through grooves are formed in the two walls of the second annular groove, and a clamping arm is located in the second annular groove; a through hole is formed in the clamping arm; and the through hole and the through groove are fixed through a fixed metal rod in a run-through mode, so that the azimuth angle is adjusted. The antenna bracket has the advantages that the azimuth angle and the radialdistance of the antenna are more flexible and accurate, and the installation cost and time are saved.

The invention discloses a far field voice input device. The device includes a remote control and a host end module; the remote control includes an infrared signal microcontroller, buttons and an infrared light emitting diode; and host end module includes microphone arrays, two photodiodes, a microcontroller, two operational amplifiers and two baffle plates; two independent microphones are used forcollecting voice signals in real time; and the two photodiodes are used for receiving infrared rays emitted by the infrared signal microcontroller, and realizes the angle positioning from the remotecontrol to the host end module. Compared with the prior art, the infrared buttons can be adopted to arouse a voice identification function, and accurate arousing can be realized by fully utilizing existing remote controls. The angle positioning of a sound source can be realized through the adopted two photodiodes, the baffle plates and other mechanisms; the microphone arrays can be adjusted to bean azimuth solution during Beamforming according to the angle of the sound source, so that best noise elimination can be realized, and the accuracy of voice identification can be guaranteed; and the device is simpler in structure, and more convenient and flexible in operation and usage.
