By installing the connecting piece 90 on the belt of the transmission mechanism 40, the pallet frame 30 is connected to the belt through the connecting shaft 60 and the connecting piece 90. Therefore, during the movement of the belt, the pallet frame 30 can be driven together by the connecting piece 90 and the connecting shaft 60. sports. The belt traction is a soft motion, and since the first and second limiting members are not in the same plane as the guide rail mechanism 20, the pallet rack 30 may have movement misalignment due to uneven force during turning. , And by providing a waist-shaped hole 91 on the connecting piece 90, one end of the connecting shaft 60 can movably pass through the waist-shaped hole 91, so that the connecting shaft 60 can move in the waist-shaped hole 91 when the tray frame 30 turns. Therefore, the movement misalignment deviation can be offset, and the reliability of the right-angle turning guide rail device 100 can be further improved.

Preferably, the number of connecting pieces 90 and connecting shafts 60 are the same, and each connecting shaft 60 is matched with one connecting piece 90. The number of connecting pieces 90 on the belt can be one, or two or more. The number can be flexibly selected according to customer needs.

The foregoing embodiments are only preferred embodiments of the present invention, and cannot be used to limit the scope of protection of the present invention. Any insubstantial changes and substitutions made by those skilled in the art on the basis of the present invention belong to the present invention. The scope of protection required.
