用于中空管件的快速联接固定。
专利摘要
提供一种用于中空型材或管件的联接弹簧销。该联接弹簧销包括基座弹簧元件和连接到弹簧元件的螺栓。弹簧元件设有法兰和至少两个弯曲弹簧舌。螺栓垂直立于法兰上，两个弯曲弹簧舌从法兰向下延伸。螺栓可设有螺栓套以可靠地防止剪切。螺栓套在其下部区域可设有环形槽，并且螺栓套可在注塑工具中周向（注射）模制在基座上，使得法兰的塑料材料可填充环形槽，从而允许螺栓套以不可拆卸且稳定的方式连接到弹簧元件。
Original abstractA coupling spring pin is provided for use in hollow sections or tubes. The coupling spring pin comprises a base spring element and a bolt connected to the spring element. The spring element is provided with a flange and at least two bent spring tongues. The bolt stands perpendicularly on the flange and the two bent spring tongues extend downwards from the flange. The bolt may be provided with a bolt case in order to securely prevent shearing. The bolt case, in its lower region, may be provided with an annular groove and the bolt case may be peripherally (injection) molded on the base in an injection molding tool, so that the plastic material of the flange may fill out the annular groove, which allows the bolt case to be connected to the spring element in an undetachable and stable manner.
