Automatic central lock for container

Abstract

The invention discloses an automatic central lock for a container. The automatic central lock comprises a lock plate. A lock body and a lock hook are disposed on the upper side and the lower side of the lock plate correspondingly. Convex lugs are disposed at the two ends of the top of the lock body. A limiting step is disposed at the position, connected with the convex lug, of the side wall of oneside of the lock body. The automatic central lock for the container realizes an anti-rotation function by its limiting structure instead of original rocker arm, pin and other mechanical connection type limiting structures and is easy to operate.

Description

technical field [0001] The invention relates to the field of container locks, in particular to an automatic intermediate lock for containers. Background technique [0002] During the stacking and transportation of the container, it needs to be automatically locked in the corner fittings of the container to have a good positioning, so as to realize the accurate connection of the upper and lower corner fittings of the container. Most of the fully automatic locks currently on the market are equipped with a mechanically connected position-limiting structure. For example, the rocking arm rotates around the pin shaft. After the automatic lock is in place, it is locked by the rocking arm to prevent the automatic lock from rotating. When taking off the automatic lock, manual operation is required to change the state of the rocker arm to remove the automatic lock. This type of mechanically connected position-limiting structure has high installation costs, is easily damaged, and is ...
