Special container door locks are usually used for container transport vehicles to secure containers, and they are also often used for direct connection between the top and bottom of the container. In the transportation process, there are many hidden safety hazards caused by the use of locks or the quality of the locks. .

Container locks, container transportation is the safest carrier of modern cargo transportation, and safety is the "lifeline" of container transportation. Once the box body carrying more than ten tons of cargo slips or rolls over from the car body, it will cause immeasurable losses to the safety of human life and property. Therefore, a special lock must be used to connect and fix the container with the car body. With the improvement of modern manufacturing technology, the manufacturing process of container turn locks has become more and more perfect and standardized. Manufacturers of container door locks strictly control key links such as raw material procurement, production management, and product testing to ensure product quality.

The main features of container locks are: convenient and flexible operation, high safety and reliability, and long service life. After surface treatment of container locks, the surface of the parts has high corrosion resistance, damp heat resistance, salt spray resistance and other characteristics, which can meet the conditions of use in coastal areas and hot and humid climates. In addition to looking at the appearance of the product, we must pay more attention to the internal quality. The internal quality of the rotary lock is extremely strict. The physical and chemical properties of the parts must meet the relevant standards. The lock shaft must pass strict tensile test requirements.

A container transport vehicle can be equipped with the same type of turn locks, or several types of turn locks can be used together, but regardless of the form, the purpose is to ensure that the container is tightly connected during transportation.

1. Some container locks are directly welded to the body, and the lock head of the container lock can only rotate but cannot move longitudinally. This type of lock is called a fixed lock

2. The turn lock of some container locks is fixedly connected to the body through a bracket. The lock head of the container lock can not only rotate but also longitudinally retract. When not in use, the lock head of the container lock can be lowered below the bearing surface to apply different standards. Box type, this type is called lift type

3. The turn lock of some container locks is hinged on the car body or made movable, so that the fastening position can be adjusted, which greatly improves the utilization rate of the vehicle; there is also a plug-in turn lock, container The lock shaft of the lock extends into the fixed part of the box like a bolt, and is generally used in conjunction with other types of rotary locks

Container door locks are also widely used in special containers. Container houses, storage containers, and equipment containers can be used in non-standard places to play a fixed connection.

There are many ways to connect the container door lock and the car body. Some are directly welded to the car body. The lock head can only rotate but cannot move longitudinally. This is called a fixed type; some turn locks are fixedly connected to the car body through a bracket. The head can not only rotate but also longitudinally expand and contract. When not in use, the lock head can be lowered below the load-bearing surface to suit different standard box types. This type is called a lift type; some turn locks are hinged on the car body or made Can be moved, so that the fastening position can be adjusted, thereby greatly improving the utilization rate of the vehicle; there is also a plug-in turn lock, the lock shaft extends into the fixed part of the box like a bolt, generally with other types of turn locks With the use of.
