Linear chain for linear transport of logistics

摘要

The present invention relates to a linear chain for linear transport of goods. Both side walls of the linear angular chain block of the present invention are formed in a stepwise manner so that the chain is joined to the side walls of the stepped structure at the time of engaging the front and rear chain blocks and the wedge connection is made between the protruded pieces formed at the both side walls and the groove And a tension spring is interposed between the chain blocks, so that the wedge connection between the chain blocks is made stronger. Since the linear chain of the present invention has high rigidity in the up and down and left and right directions in the straight section, there is no need for a separate means for supporting the free end of the chain and it is advantageous in that it can be easily installed in a narrow space.
