An automatic lock for a container

Abstract

The invention relates to an automatic lock for a container. The automatic lock for the container comprises lock head, a rotary shaft body, a compression spring, a base and a sliding body, wherein the lock head, the rotary shaft body, the base and the sliding body are of a cast alloy steel structure. According to the automatic lock for the container, linear movement in the vertical direction can be converted into rotational movement on the horizontal plane, all the parts of the automatic lock are connected in a tooth meshed mode, or all the parts of the automatic lock are connected through bolts or cylindrical pins, namely, the upper portion of the sliding body is connected with the lock head in the tooth meshed mode, and the lower portion of the sliding body is connected with the rotary shaft body in a meshed mode, and thus rotational movement of the lock head is achieved. The automatic lock is converted to be in a normal state form the working state by means of the spring in a main part. Due to the unique architectural feature of the automatic lock for the container, the automatic lock can rotate automatically through an external load provided by the gravity of the container so that locking can be achieved, and otherwise, the external load is removed when the container is lifted, and the automatic lock can rotate automatically to achieve unlocking. The automatic lock for the container is simple in structure, high in automation degree, high in bearing capacity, low in manual cost, and high in abrasion and corrosion resistance.

Description

technical field [0001] The invention relates to an automatic lock for containers, which is an automatic lock used in the field of cargo transportation safety; such as railways, highways, ships, etc., which need to use containers to transport goods. Background technique [0002] The container locks used in the existing freight field generally adopt manual or semi-automatic locks. This type of lock has high safety performance, but it is labor-intensive and dependent on the staff, and there are certain safety hazards. The occurrence of these accidents brought huge losses. In addition, the working principle of the fully automatic locks currently used in the market is that the corner fittings of the container and the lock head are rubbed and squeezed against each other to make the container rotate slightly relative to each other, thereby realizing the locking and unlocking functions. This type of lock mainly relies on the guide slope of the lock head, and the guide slope is pron...

AI Technical Summary

Problems solved by technology

This type of lock mainly relies on the guide slope of the lock head. The guide slope is prone to wear and other problems after repeated friction, which affects the locking function.
