See fig. 11-14 for specific structural and functional implementations of lock 14.

Fig. 11 shows a specific structure of the lock 14. The lock rear plate 32 is surrounded by the right and left side car plates 6, 7 and the lock front plate 31, and only the degree of freedom in the up-down direction is left. The lower portion of the latch back plate 32 is held against by the latch bottom spring 35 and the upper portion is restrained from upward movement by the latch top stop 29. The lock back plate 32 is fixedly connected with the lock pressing rod 30. A lock bolt compression spring 34 is mounted within the lock back plate 32. In a natural state, the lock back plate 32 is jacked up by the lock bottom spring 35, the upper plane of the lock back plate 32 clings to the lower plane of the lock upper baffle 29, and the lock bolt pressure spring 34 is right behind the lock bolt 33.

Fig. 12 is a partial sectional view of the lock 14 mounted on the left side car plate 7, with the left roof door panel 3 fully opened. At this time, the lock back plate 32 of the lock 14 is at the highest position (the position where the lock back plate 32 is tightly attached to the lock upper baffle 29), the lock bolt 33 corresponds to the lock bolt pressure spring 34 in position, and if the lock bolt 33 receives external thrust, the lock bolt pressure spring 34 can be extruded and retracted into the space where the lock bolt pressure spring 34 is located. In a natural state, the lock tongue 33 is pushed by the lock tongue compression spring 34, and the lock tongue 33 extends out of the lock front panel 31.

Fig. 13 is a partial sectional view of the lock 14 mounted on the left side deck 7, with the left roof door panel 3 fully opened, and with the cargo box 23 placed in the vehicle compartment 1. At this time, the lock tongue 33 can flexibly move back and forth when the lock rear plate 32 of the lock 14 is at the highest position (the position where the lock rear plate 32 is tightly attached to the lock upper plate 29). The container is being put into or taken out upwards, and at this time the container 23 is not completely in place, the lock tongue 33 does not fall into the fixing groove 36 on the container 23, the lock tongue 33 is pushed back by the side wall of the container 23, and the lock tongue compression spring 34 right behind the lock tongue 33 is extruded to enter the space where the lock tongue compression spring 34 is located, so that the container 23 can smoothly enter or be taken out of the compartment 1.

Fig. 14 is a partial sectional view of the lock 14 mounted on the left side car plate 7, with the left roof door panel 3 closed. At this time, since the left roof door panel 3 is closed, the latch pressing lever 30 is pressed down by a certain distance, so that the latch rear plate 32 moves down together with the latch spring 34, pressing the latch bottom spring 35. Meanwhile, the lock bolt 33 and the lock bolt pressure spring 34 are not at the same height, and the lock bolt 33 cannot move backwards under the stress condition and is locked in an extending state. If the container 23 is installed in the carriage 1, the lock tongue 33 goes deep into the fixing groove 36 of the container 23 to fix the container.

Fig. 15 is a partial sectional view of the left side car with the two container 23 locks 14 mounted on the left side deck 7, with the left roof door panel 3 closed, in view A-A of fig. 5.

The upper and lower two-layer cargo boxes 23 are arranged in the left carriage, and the positioning side stop block 12 and the positioning middle stop block 13 play a left-right limiting role on the cargo boxes 23. The locks 14 are secured in place from both sides of the container. When the car roof door panels 2 and 3 are closed, the lock pressing rod 30 is pressed down, the lock bolt 33 and the lock bolt pressure spring 34 are dislocated, the lock bolt 33 cannot be retracted back into the lock upper baffle 29, and only can extend into the container side clamping groove 36, and after the container side clamping grooves 36 are supported by the lock bolt, the upper and lower directions and the front and rear directions of the container side clamping grooves are limited and fixed. The advantage is that the containers can be fixed at the place where they are placed without densely distributing, any one or a plurality of containers 23 in each layer can be directly taken out or put in during transportation, the fixation of other containers 23 in situ is not affected, the time is saved, and the containers 23 are convenient and flexible to take and put.

The structure of the cargo box 23 is shown in fig. 16 and 17. The left and right sides of the cargo box 23 are provided with a cargo box side clamping groove 36 structure, the top surface of the cargo box 23 is provided with a cargo box top four-claw hole 37, and the cargo box 23 is used for being matched with an unmanned mechanical arm provided with four claws.

The cargo box 23 has a fixed dimension in the right-left direction corresponding to the distance between the positioning side stopper 12 and the positioning middle stopper 13 inside the vehicle compartment 1. The cargo box 23 may have different lengths in the front-rear direction, depending on the size of the cargo to be loaded. The container side engaging grooves 36 on the left and right side surfaces of the container 23 are spaced apart at the same intervals as the front-rear direction of the lock 14 in the vehicle compartment 1. The cargo box 23 is designed to be two layers in the up-down direction, and each layer of cargo box 23 corresponds to the structure of two rows of lock bolts 33 on the lock 14. The height of the cargo box 23 can also be changed according to actual needs, and the height can be reduced, more than three layers can be placed in the carriage, or the height can be increased to be consistent with the height in the carriage 1, but the arrangement position of the lock bolt 33 needs to be synchronously modified.

The lock 14 and the container 23 are fixed in a limiting and fixing structure mode, and the container can be fixed in a placing position without being densely distributed. During transportation, any one or a plurality of containers 23 in the top container 23 can be directly taken out or put in without affecting the fixation of other containers 23 at the original positions, and the time for taking and putting the containers 23 is saved, and the convenience and the flexibility are realized.

The container 23 is fixed in the carriage 1 by using a full mechanical mode, and whether the lock tongue 33 in the lock 14 locks the container 23 is determined by the opening and closing states of the carriage top door plates 2 and 3. After the carriage top door plates 2 and 3 are opened, the lock bolts 33 are automatically unlocked and can be forced to retract into the lock 14, and the container can be moved. After the roof door panels 2 and 3 are closed, the lock bolts 33 are locked and cannot retract backwards, and are clamped in the container side clamping grooves 36 to fix the container in the front-back, left-right and up-down directions. The container 23 is limited and fixed in the carriage 1, or can be switched in a removable state, and is linked by opening and closing the carriage top door plates 2 and 3, so that the use is convenient, time-saving and labor-saving, and the safety and reliability of the full mechanical structure are higher.

The limiting and fixing structures of the container 23 are arranged on two side surfaces of the container, and other surface positions of the container can be designed into different grabbing structures according to different use of the carrying tools, such as screw holes for installing lifting appliances are reserved on the top surface of the container.

The cargo box 23 is not limited to use in an unmanned loading and unloading system, and may be manually transported and loaded for fixation. During manual carrying, the rear carriage plate 5 can be made into a movable state, such as upturning, downturning, double opening and the like, if necessary. In this way, the cargo box 23 can be pushed into the vehicle compartment 1 from the rear of the vehicle compartment 1 to a predetermined placement position, and when pushed in the front-rear direction, the lock 14 is in a natural state because the roof panels 2, 3 are open, the lock tongue 33 can be automatically retracted when encountering the cargo box 23, and the cargo box can be pushed back and forth in the vehicle compartment 1. Or it is also possible to put the cargo box 23 into the vehicle compartment 1 by a machine and then push it to a predetermined placement position by a worker.
