Description

Technical Field

[0001] The invention relates to the field of container lock seats, in particular to a split container lock seat structure, a truck compartment and a method. Background Art

[0002] The statements in this section merely provide background information related to the present invention and do not necessarily constitute prior art.

[0003] With the increasing requirements for environmental protection, low-carbon transportation has become more and more important. Currently, container transportation is a mainstream low-carbon transportation method, and container locks are widely used as an important accessory in this transportation. However, in the existing technology, reference Figure 1 As shown, an integrated lock seat 9 is adopted, and a lock head is arranged in the middle of the integrated lock seat, which is connected with the container by the lock head. The integrated lock seat 9 has a complex structure, and the device often needs to be processed and manufactured by casting or other methods, which leads to high production costs and inconvenient installation and operation. In addition, the integrated lock seat 9 also needs to open corresponding lock slot holes at the relevant supporting parts of the vehicle body (such as side beams) for installation. The opening of the lock slot holes will affect the strength and rigidity of the relevant supporting parts of the vehicle body, shorten the service life of the vehicle body, and increase the repair and maintenance costs; and the integrated lock seat protrudes from the vehicle body, which limits the use scope of the truck compartment, and is mainly used to fix the container.

[0004] Chinese patent application CN2006201338849 discloses a rolling locking device for railway container vehicles, which includes a lock body part and a stop seat. The lock body part can be turned over to the inside of the vehicle, and the stop seat part can also be turned over. After the stop seat part is turned up, the lock body part can be turned over to the inside of the vehicle to achieve storage of the lock body part. Although it can achieve storage of the lock body, the problem is that the structure is complicated and both parts need to be turned over. When both parts are turned over, the lock body part is turned down to the inside of the vehicle body, and a lock slot hole needs to be opened on the surface of the vehicle body, which affects the strength of the vehicle body. In addition, multiple turns are required to achieve storage of the lock body, making the operation not convenient enough. Summary of the invention

[0005] In view of the deficiencies in the prior art, the object of the present invention is to provide a split container lock seat structure which is simple in structure, economical and practical, and easy to manufacture and install.

[0006] In order to achieve the above object, the present invention is implemented through the following technical solutions:
