As shown in Figure 18, use the lifting frame 4 and the steel wire rope 3 to lift the box body. The bottom end of the steel wire rope 3 is fixed on the corner fitting 19 at the bottom end of the container 1, and the steel wire rope 3 at the bottom is close to the side of the container 1. After lifting a certain height at the same height before and after the body, as shown in Figure 19, the front end of the lifting container 1 is lifted so that the front end is higher than the door end provided with the box door 12, and the box body is inclined. At this time, the wire rope 3 (the flange on the wire rope 3 itself or the wire rope 3) applies pressure to the drive shaft 134 of the bottom lock 13, thereby opening the bottom lock 13, so that the chamber door 12 is automatically opened. the

The goods in the box are automatically unloaded due to the gradient produced by the height difference. When the goods are unloaded, the front end is lowered to make the box body horizontal, and the steel wire rope 3 (the steel wire rope 3 itself or the flange on the steel wire rope 3 ) is separated from the drive shaft 134, Bottom lock 13 returns automatically because of the pressure of return spring 13, and chamber door 12 also automatically re-locks with bottom lock 13 because of deadweight. the

To sum up the above, the container with the bottom lock of each embodiment of the utility model acts on the drive shaft 134 at the bottom of the container 1 from the side by an external force, thereby opening the bottom lock 13 of the container 1, avoiding the need to open the container 1 directly from the door end. The box door 12 improves the safety factor. In the container 1 with the bottom lock 13 of the present utility model, at least one end of the drive shaft 134 is provided with a telescopic telescopic shaft 138 to ensure that the overall size of the box does not exceed the ISO requirement; at the same time, the bottom lock 13 The return spring 133 can be used to automatically return, and at the same time, the arc structure of the bottom lock 13 can be used to realize automatic locking; the method for opening the container with the bottom lock in the embodiment of the utility model uses the wire rope 3 to open the bottom lock 13, The manual operation is avoided, and the safety performance is improved. At the same time, the goods in the box can be unloaded automatically when the box door 12 is opened, which improves the unloading speed. the
