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.

Disclosed is a hydraulic expansion union joint which is characterized in that the hydraulic expansion union joint comprises a concave joint; the concave joint is provided with a central hole; an annular concave groove is arranged on the inner surface of the central hole; the union joint also comprises a convex joint; the lower segment of the convex joint is provided with a radial perforation; both ends of the radial perforation are provided inner threads; one end of an oil inlet-outlet hole is communicated with the radial perforation with the other end extended out of the oil inlet-outlet hole; a segment of the convex joint is movably arranged in the central hole of the concave joint; 2 connecting components are respectively arranged on both ends of the radial perforation; each connecting component is composed of a locking screw ring provided with an outer thread and fixedly connected with the thread of the radial perforation, and a movable small shaft provided with an annular lug boss on one end and nested with a spring and a seal ring; the movable small shaft is arranged in the radial perforation with one segment movably nested with the locking screw ring. The hydraulic expansion union joint is adopted to have the advantages of rapid and convenient connection and separation, being applicable to the movable connection between the carriages of the automobiles or trains controlled through the hydraulic mode, the movable connection between the drilling rods in the geological petroleum drilling and the devices for the urban garbage disposal.

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.

The invention relates to a dynamic navigation method in navigation and a device thereof. The existing navigation mode can not adapt to the requirement of rapid positioning and navigation of a moving target. The method aims at solving the problem of accurate navigation when the target is in the moving state. The method comprises the following steps: the information about longitude, latitude, moving direction and the like of the target is transmitted to a user terminal view in the manner of short messages for a plurality of times when the target moves dynamically; the user terminal receives theposition coordinate information for a plurality of times, refreshes the user terminal view and displays the latest position coordinate information of the target; and a user can accurately and quicklyarrive at the location of the moving target according to the latest target navigation information of the terminal view. The device comprises a call center system, a center terminal, a satellite navigation terminal and a wireless communication base station.
