The invention discloses a dumper turnover structure, which belongs to the technical field of auto spare parts and comprises two positioning seats, and central shaft sleeves are fixedly mounted in the positioning seats; overturning shaft sleeves are rotationally mounted in the central shaft sleeves, and a connecting shaft sleeve is detachably and concentrically connected between the two overturning shaft sleeves in a sleeving manner; a lock cylinder assembled on the annular support in a penetrating mode is fixedly installed in the center shaft sleeve, and a lock head is fixed to one end of the lock cylinder. A screw is assembled in the central shaft sleeve through threads, and a lock control conical head is fixed to the end, facing the annular support, of the screw; a first lock hole and a second lock hole are formed in the side walls of the overturning shaft sleeve and the connecting shaft sleeve correspondingly. The lock control conical head can be driven to move towards the position where the annular support is located by rotating the screw clockwise, at the moment, the lock control conical head can abut against and push all the lock heads to be inserted into the first lock hole and the second lock hole at the same time, and therefore locking between the connecting shaft sleeve and the overturning shaft sleeve is completed; on the contrary, dismounting can be completed; the overturning shaft sleeve is fast and convenient to disassemble and assemble.

    本发明公开了一种自卸车翻转结构,属于汽车配件技术领域,包括两处定位座,定位座内部固定安装有中心轴套;中心轴套的内部转动安装有翻转轴套,两处翻转轴套之间可拆卸式地同心套接有连接轴套;中心轴套的内部固定安装有贯穿装配于环形支架上的锁芯,锁芯的一端固定有锁头;中心轴套的内部通过螺纹装配有螺杆,螺杆朝向环形支架的一端固定有锁控锥头;翻转轴套和连接轴套的侧壁上分别开设有锁孔一和锁孔二。本发明通过顺时针旋转螺杆可驱动锁控锥头向环形支架所在处移动,此时锁控锥头可同时抵推所有锁头插接于锁孔一和锁孔二内,从而完成连接轴套与翻转轴套之间的锁定;反之即可完成拆卸;其在拆装翻转轴套时既快捷且又方便。
