Pipeline annular surface quick mounting and locking device

The invention relates to a pipeline annular surface quick mounting and locking device. The pipeline annular surface quick mounting and locking device is mounted on a working table through third boltsand further comprises a lock body, a locking pin, a rotating wheel, a pressing plate, a cylindrical locking elastic bead, a handle, first bolts and a second bolt. A quick plugging and pulling structure is formed by the parts, so that the locking pin is quickly inserted into the annular surface of a pipeline, and the function of preventing the locking pin from moving backwards is achieved. The cylindrical locking elastic bead can ensure the working stability of the locking pin moving forwards or backwards correctly, the locking pin is prevented from moving back and forth due to interference andaffecting the fixing, disassembly and assembly of a working body during work, and a pressure pipeline can be quickly and reliably sealed. 一种管道环面快速安装锁紧装置，通过第三螺栓安装在工作平台上，该装置还包括锁体、锁紧销、转轮、压板、柱形锁紧弹珠、手柄、第一螺栓、第二螺栓。本发明通过上述部件构成一个快速插拔结
