As shown in fig. 1 and 2, the front end and the rear end of the outer side surface of the wing 1212 of the sliding plate 121 are respectively provided with a first guide roller 123 having an axis extending along the transverse direction, the front end and the rear end of the left upright plate 111 and the right upright plate 112 are respectively provided with a roller slot 118 engaged with the first guide roller 123, and preferably, the roller slot 118 penetrates through the left upright plate 111 and the right upright plate 112 along the thickness direction (i.e., the left-right direction). The first guide roller 123 is pressed against the lower side of the roller groove 118 and can roll or slide on the lower side of the roller groove 118.

When the first guide roller 123 moves to the rear extreme position, part or all of the unpowered rollers 122 at the rear side extend out of the base; when the first guide roller 123 moves to the front limit position, part or all of the unpowered rollers 122 at the front side extend out of the base.

Further, in order to prevent the sliding frame from moving left and right relative to the base, as shown in fig. 4 and 5, at least two second guide rollers 124 are disposed on both left and right sides of the web 1211 of the sliding plate body 121, and an axis of the second guide roller 124 extends in a vertical direction. The second guide roller 124 located on the left side is pressed against the inner side surface of the left vertical plate 111 (the side opposite to the left vertical plate 111 and the right vertical plate 112 is the inner side), and can roll or slide back and forth along the inner side surface of the left vertical plate 111. Similarly, the second guiding roller 124 on the right side is pressed against the inner side surface of the right vertical plate 112, and can roll or slide back and forth along the inner side surface of the right vertical plate 112. Preferably, two second guide rollers 124 are disposed on both left and right sides of the web 1211 of the sliding plate body 121, and the two second guide rollers 124 are arranged in a matrix of two rows and two columns.

If the recess 1181 is not formed in the middle of the roller slot 118, the height of the unpowered roller 122 is the same as the height of the conveying chain and the height of the conveying member (e.g., the conveying chain) of the conveyor 3 in the process of butting the RGV car with the conveyor 3, so that the unpowered roller 122 can play a role of supporting when serving as a bridge. When the RGV trolley is used for self-transporting goods, the connecting device 1 is retracted inside the RGV trolley, namely, the sliding frame body in the connecting device 1 is retracted inside the base. Because the goods are conveyed on the RGV at a certain distance, if the concave part 1181 is not arranged in the middle of the roller groove 118, the height of the unpowered roller 122 is the same as that of the conveying chain of the RGV, and thus, in the process of moving the goods on the RGV, the goods are in contact with the unpowered roller 122, so that the resistance is large, and the goods are not favorable for being conveyed on the RGV. After the recessed portion 1181 is provided, when the sliding rack body in the docking device 1 is to be retracted into the base, the unpowered roller 122 may move downwards along the recessed portion 1181 of the roller slot 118, and the height of the unpowered roller is lower than the conveying chain of the RGV trolley, so that the unpowered roller does not contact with the pallet goods, and the increase of resistance is avoided.
