The locking device comprises a fixing block, a connecting column is rotationally connected to the middle position of the bottom of the fixing block, positioning supporting plates are fixedly connected to the tops of the outer walls of the two sides of the fixing block, and locking devices are rotationally connected to the outer walls of the two sides of the positioning supporting plates. The two sides of the top of the locking device are fixedly connected with protective top shells, and the side, away from the positioning supporting plate, of the locking device is fixedly connected with a connecting plate. According to the locking method and device suitable for the rear box door of the dump truck, the connecting plate is matched with the connecting column, so that the contact surface of the locking device and the rear box door is increased when the locking device and the rear box door are fixed, the stability of the locking device during working is improved, and a locking rod is driven by a transmission rod to rotate; therefore, the probability that after the rear box door is locked, the rear box door is still loosened is reduced, and the problem that goods loaded on a vehicle are leaked due to the fact that the rear box door is locked and loosened is effectively solved.

    本发明公开了一种适用于自卸翻斗车后箱门的锁止方法及装置,包括固定块,所述固定块的底部中间位置转动连接有连接柱,所述固定块的两侧外壁顶部固定连接有定位支撑板,所述定位支撑板的两侧外壁转动连接有锁紧装置,所述锁紧装置的顶部两侧固定连接有防护顶壳,所述锁紧装置远离定位支撑板的一侧固定连接有连接板,本发明涉及自卸翻斗车技术领域。该适用于自卸翻斗车后箱门的锁止方法及装置,连接板与连接柱进行配合,从而增大了锁紧装置与后箱门固定时的接触面,有利于增大锁紧装置工作时的稳定性,锁紧杆在传动杆的带动下进行旋转,从而降低了后箱门锁紧后仍会出现松动的概率,有效的避免了车辆装载的货物因后箱门的锁紧松动出现泄露的问题。
