  • Patent number: 11418553
    Abstract: The present disclosure relates to a video connection method and apparatus. The method includes: obtaining matched video connection requests from a plurality of video connection requests; creating a video connection room for the matched video connection requests; generating identification information of the video connection room; and informing a first client and a second client of entering the video connection room and making a video connection by sending the identification information of the video connection room to the first client and the second client corresponding to the matched video connection requests respectively.

  • Patent number: 11345382
    Abstract: A pallet truck according to the present application includes a front frame, a rear frame, a lifting component, two fork bodies, a guide bar, a transmission device, and a load-bearing wheel assembly. The distance between the fork bodies can be adjusted by using the side-shifting driving component, thereby providing different fork distances and significantly improving the adaptability. During the adjusting process, the transmission device can switch the load-bearing wheel assembly from the longitudinal rolling state to the lateral rolling state, thereby avoiding wear of the wheels, which is beneficial to improving the overall life of the device and reducing the maintenance cost. In addition, the transmission device is pushed out as the rear frame is lifted, and thus the operation process is simple and reliable.
