The invention discloses a locking device and a tire burst safety emergency device. The locking device comprises a first connecting piece and a second connecting piece. Each of the first connecting piece and the second connecting piece comprises a connecting plate, and the two connecting plates are parallel and oppositely arranged; pressure bearing blocks are arranged on the connecting plates, andtwo locking blocks used for holding and loosening the pressure bearing blocks are connected between the two connecting plates in a sliding mode. And in a length direction of each connecting plate, thetwo locking blocks are connected through a connecting fastener. The tire burst safety emergency device comprises a supporting ring, the supporting ring comprises a plurality of supporting pieces, every two adjacent supporting pieces are movably connected, and the two ends of the supporting ring are connected through the locking device. In the invention, the two locking blocks tightly hold the pressure bearing blocks through the connecting fasteners, axial locking in the length direction of the connecting plates is converted into opposite movement between the two connecting plates, then circumferential locking of the tire burst emergency safety device is achieved, a crown does not need to be flattened, operation is convenient, and the quality and efficiency of installation of the tire burst emergency safety device are improved.

    本申请公开一种锁紧装置及爆胎安全应急装置,锁紧装置包括第一连接件和第二连接件,第一连接件和第二连接件分别包括一连接板,两个连接板平行且相对设置;连接板上设置有承压块,两个连接板之间滑动连接有用于抱紧和松开承压块的两个锁紧块;在连接板的长度方向上,两个锁紧块通过连接紧固件相连接。爆胎安全应急装置包括支撑环,支撑环包括多个支撑片,相邻两个支撑片活动连接,支撑环的两个端部通过上述锁紧装置相连。本申请采用连接紧固件使两个锁紧块抱紧承压块,把沿连接板长度方向的轴向锁紧转变为两个连接板之间的相向移动,进而实现爆胎应急安全装置的周向锁紧,无需压瘪胎冠,操作方便,提高了安装爆胎应急安全装置的质量和效率。
