The unidirectional passing assembly 2 is contracted in the box body 1, so that the sliding of the container 300 is not limited any more, and the container 300 can enter the container 300 transportation equipment along the inclined surface because the box body 1 is inclined; after the container 300 is completely put into the container 300 conveying device, the handle 55 controls the guide block 51 to move downwards in the vertical groove, so that the lower support arm 54 is separated from the locking cavity, the locking block 432 is not limited at this time, the compression spring 434 is restored from the compressed state to the initial state, the main sliding block 431 is driven to move to one side far away from the front limiting block 41, and the main connecting rod 3 moves clockwise around the main connecting shaft 31 in the process, so that the release block 22 and the release wheel 23 extend out of the opening 11 to wait for the next container 300 loading.

As shown in fig. 4 and 5, in the present utility model, the main link 3 is in a horizontal state in an initial state, and the auxiliary link 436 is perpendicular to the main link 3; the main link 3, the main connecting shaft 31, the auxiliary link 436, the shaft of the auxiliary link 436 connected with the main link 3, the main slider 431, and the link mechanism formed by the shaft of the main slider 431 connected with the auxiliary link 436 rely on the pretightening force provided by the two compression springs 434 to enable the slider to have a rightward movement trend, and the slider passes through the dead point of the auxiliary link 436 in the vertical direction and resists the backward limiting, so that the main link 3 is in the horizontal position.

The utility model can not only stably and reliably execute cargo loading and unloading tasks, but also reduce the cost of the traditional loading and unloading system and solve the problem of loading and unloading safety in the prior art, and simultaneously can be extended to the field of automatic production lines or the field of aviation gravity air drop to block, position and release objects on a production line (in a cargo warehouse), and the utility model has the advantages that the main connecting rod 3, the front guide rod 433 and the actuating assembly 44 are arranged in two groups, so that the double-redundancy actuating design is realized, the reliability of the device is improved, and the safety of the loading and unloading system is further improved.

Example 2:

as shown in fig. 1-12;

a transport table includes a table 100, and sets of stop release one-way pass-through devices 200 mounted on the table 100 and as described above.

The workbench 100 is a workbench 100 which is lifted vertically and can incline in the horizontal direction, the one-way passing device 200 for limiting release is arranged on the workbench 100, and when the workbench 100 inclines, the one-way passing device 200 for limiting release also inclines; thereby enabling the container 300 to be prevented from being on the case 1;

further, a mounting groove is formed in the workbench 100, the limited release unidirectional passing device 200 is mounted in the mounting groove, and the top of the box body 1 and the top surface of the workbench 100 are on the same plane; this allows the one-way pass-through assembly 2 to extend or retract within the table 100 depending on the needs of the user; thereby realizing the limit of the container 300 positioned on the workbench 100; the sliding of the container 300 during loading or unloading is prevented.

Further, the one-way passing device 200 is symmetrically arranged; the container 300 transported to the station 100 will be located between two sets of the restraint release one-way pass devices 200 that are symmetrical;

when the container 300 is transferred from the transporting device to the workbench 100, the workbench 100 is inclined to one side of the transporting device, the whole container 300 moves to the workbench 100 under the action of the transporting device, and during the transportation process, the container 300 applies a force to one side of the unidirectional passing assembly 2 away from the main connecting rod 3, so that the unidirectional passing assembly 2 moves into the box body 1;

when the whole container 300 is conveyed to the workbench 100 and is positioned between the two groups of symmetrical unidirectional passing assemblies 2 and is no longer in contact with the top of the unidirectional passing assemblies 2, the driving release shaft is restored to the initial state under the action of the torsion springs 24, so that the release wheels 23 and the release shaft penetrate through the opening 11 to form a limiting structure, and the container 300 is limited to slide out;

subsequently, the table 100 is adjusted to a horizontal state, and the container 300 is transported to the container 300 transporting apparatus by the table 100;

the container 300 is unloaded from the workstation 100 and is entered into the container 300 transport facility:

firstly, the workbench 100 is controlled to lift and incline to one side of the transportation equipment close to the container 300;

the actuating mechanism controls the main sliding block 431 to move to the side close to the front limiting block 41, and the lower support arm 54 enters the locking cavity to complete locking of the main sliding block 431, at the moment, the release wheel 23 is positioned in the box body 1 and is not used for limiting the container 300, and the container 300 can slide on the workbench 100 and enter the container 300 conveying equipment until the container 300 is transported;

subsequently, the lower arm 54 is controlled to slide out of the locking cavity, the main slider 431 is not locked any more, and the compression spring 434 will return from the compressed state to the initial state, thereby enabling the release wheel 23 to be driven out of the opening 11.

The utility model is not limited to the specific embodiments described above. The utility model extends to any novel one, or any novel combination, of the features disclosed in this specification, as well as to any novel one, or any novel combination, of the steps of the method or process disclosed.
