The specific meaning of the above terms in the present application can be understood by those skilled in the art as the case may be.

The present application is described in further detail below with reference to fig. 1-2.

In one aspect, a locking device is provided, comprising:

the cylinder body 1 is used for being arranged on the side wall of the freight tray 2, one end of the cylinder body is a blocking end, and the other end of the cylinder body is opened to be an open end;

the elastic piece 3 is arranged in the cylinder body 1;

one end of each connecting rod 4 is a connecting end and is connected with the elastic piece 3; the other end is an extension end which extends towards the open end;

a bolt 5 for being disposed in a through hole of a side wall of the rail 6 and being capable of moving axially along the through hole, thereby having:

in a locked state, the bolt 5 is abutted against the extending end of the partial connecting rod 4, so that the partial connecting rod 4 compresses the elastic piece 3 to move towards the direction of the blocking end, and the freight tray 2 is fixed relative to the track 6;

in the unlocking state, the bolt is separated from the connecting rod 4, and the elastic piece 3 pushes the part of the connecting rod 4 which is abutted to the bolt in the locking state to move towards the direction far away from the blocking end, so that the freight tray 2 can move along the track 6.

With respect to the locking device disclosed in the above embodiments, it is easily understood by those skilled in the art that the position of the shipping pallet 2 on the guide rail 6 can be defined by pushing the shipping pallet 2 with the locking device to a proper position along the guide rail 6, aligning the open end of the cylinder 1 with the latch 5, and pushing the latch to move the latch 5 to a locked state; it should also be understood by those skilled in the art that the process does not require the open end to be strictly aligned with the position of the bolt 5, as long as the bolt 5 can be ensured to be within the effective surrounding range of the open end, so that the bolt 5 can be surrounded by the connecting rod 4 which is not in contact with the bolt, and the process has good adaptability and is less limited; and the locking device not only limits the movement of the freight tray 2 along the rails 6, but also limits the movement of the source tray 2 in a direction away from the rails 6.

In some optional embodiments, the elastic member 3 includes a plurality of springs, one end of each spring is connected to the connecting end of one of the connecting rods 4, and the other end is connected to the wall surface of the blocking end, and this arrangement of the locking device can ensure that only a part of the connecting rods 4 abutting against the locking tongue 5 moves toward the blocking end when the locking device is in the locking state, thereby avoiding mutual interference between the connecting rods 4.

In alternative embodiments, the extended end of each link 4 is flush with the end surface of the open end to maximize the length of the link 4 while avoiding the link 4 from scratching the side walls of the guide rail 6.

In some alternative embodiments, each of the links 4 has a rectangular radial cross-section, and the side surfaces of any two adjacent links 4 contact each other to provide a close arrangement between the links 4.

In some optional embodiments, the apparatus further comprises a limiting device for being disposed on the side wall of the rail 6, and the limiting device comprises:

in the limit state, the limit device is abutted with the bolt 5 so as to limit the bolt 5 in the locking state;
