Abstract

The invention discloses a full-automatic spin lock for a container. The full-automatic spin lock comprises a lock shaft, a lock base, a torsional spring, a lock nut, a connecting pin, a limit pin, an emergency release pin, a round pin, a gasket, a spring and an end cover. The lock head of the lock shaft has an inclined double curved surface structure, wherein a lock rod of the lock shaft passes through the lock base and the torsional spring, the lower end of the lock rod is fixed by the lock nut and the connecting pin is adopted for preventing the lock nut from loosening. The torsional spring is sleeved on the lock rod and positioned in a cavity in the middle of the lock base; and the torsional spring is formed by integrally vulcanizing an inner ring and an outer ring by a rubber layer. The emergency release pin is positioned in a groove on the side face of the lock base, and the tail end of the emergency release pin is inserted into the outer ring of the torsional spring. The full-automatic spin lock for the container can realize automatic locking and automatic unlocking of the container, is provided with a manual unlocking device under the abnormal conditions, is also provided with an indicator so as to facilitate observing the locking state of the spin lock, and improves the loading and unloading efficiency and the transportation safety of the container.

Description

technical field [0001] The invention belongs to the field of mechanical design and manufacture, in particular to the field of container transportation equipment, in particular to a container placement twist lock equipment.
