Chain link for energy supply chain and energy supply chain

摘要

Chain link for a power transmission chain for guiding cables, lines and the like, wherein the chain link has articulation elements for articulated connection with other identical chain links for forming the energy chain, wherein the chain link has two laterally spaced apart link plates with this limiting, running in the chain link longitudinal direction narrow sides, and at least one, preferably two opposite, the link plates interconnecting transverse webs, wherein at least one transverse web to form a hinge connection with respect to at least one link plate is formed pivotable and pivoting in a chain link connecting the locking position and in an intermediate space between the link plates at least partially releasing opening position can be transferred, wherein at least one pivotally trained end portion of the cross bar latching ge to the crossbar articulated link plate can be fixed, and wherein the hinge connection between the crossbar and link plate a substantially cylindrical pivot pin with a radius R1 over at least a portion of the circumference of the pin on one of the corresponding components of crossbar and chain link and a substantially cylindrical pin receiving on the other of the two corresponding Having components, characterized in that (i) the pivot pin has at least over a portion of its length on the side facing away from the narrow sides journal side at least one recess which springs back from the cylindrical surface of the pin, and in that the pin receptacle has at least one locking nose, which of the cylindrical Area of the pin receiving protrudes with radius R1 and engages in the recess, and / or that (ii) in addition to the articulation between the pivot pin and pin receptacle with radius R1 locking means are provided which between the crossbar cooperating latching in its closed position and the link plate and that limit this additional locking means the pivot angle of the crossbar in its open position.
