A containerization automatic lock

The present invention relates to a container with an automatic lock, comprising a lock, the rotary shaft, the body portion five compression spring seat body and the sliding body; wherein the lock, the rotary shaft, and sliding seat is a cast alloy steel structure; the present invention is capable of linear movement in the vertical direction into rotational motion of a horizontal plane, there engages a toothed connection, bolts or pins are connected between the cylindrical body portion of the automatic locking, i.e., the upper body and the slide lock toothed mating connector; a lower portion of the slide body to the rotary shaft mating connector body, thereby realizing a rotational movement of the locking head. This automatic lock is changed from the normal operating state by means of a spring body portion is achieved. Automatic lock unique structural features of the present container can be provided in the container by gravity rotary self-locking external load, whereas the outer container lifting the drag load, automatically lock the rotation can unlock itself; simple structure, high degree of automation, good load-bearing capacity low labor costs, wear and corrosion resistance is strong.
