<p>The present invention relates to a palette coupling device comprising: an attachment plate (11) attached to the rear side of a palette (101); both side plates (12, 12′) which are curved forwards from both ends of the attachment plate (11) and have a shaft support hole (14) at the center; an installation unit (1) including a support piece (13) attached to the inner front side of the both side plates (12, 12′); and a connection rod (2) which includes a rotary shaft (21) at one end to be inserted into the shaft support hole (14) on the both side plates (12, 12′) of the installation unit (1) to be rotated and a coupling hole (22) at the other end. Rear and front catching protrusions (15, 15′) are formed at the inner top of the both side plates (12, 12′) of the installation unit (1) at a predetermined distance from each other in a symmetrical manner. The rear and front catching protrusions (15, 15′) are separately formed in the front and rear position around the centerline of the shaft support hole (14). The front catching protrusion (15′) is positioned to be lower than the rear catching protrusion (15). The connection rod (2) has an avoiding groove (23) at both lower ends to avoid the hindrance of the front catching protrusion (15′). Therefore, the palette coupling device prevents impacts and noise in use and damage to products inside the palette.</p> |
