The invention relates to a securing pin (16) which, in order to secure two chain connector shackles (12, 14) of a chain connector (10) against becoming disengaged, can be inserted into an opening (28) formed by the two chain connector shackles (12, 14), comprising a base body (30) with a through-hole (32), at least one spring ring (34), at least two balls (36), and a securing member (38) inserted into the through-hole (32), wherein an annular groove (54) in which the spring ring is inserted (34) is provided in a lateral surface (59) of the base body (30), wherein the annular groove (54) is provided with two bore holes (66) which are aligned with the through-hole (32) and in which the balls (36) rest, and wherein the spring ring (34) has at least one leg (64) which extends in the longitudinal direction of the base body (30) and which bends out of shape if the securing pin (16) is inserted into the opening (28) incorrectly. The invention further relates to a chain connector (10) for connecting two chains formed from links and to a method for connecting two chains by means of a chain connector (10) and for securing the chain connector shackles (12, 14) of the chain connector (10) against becoming disengaged by means of a securing pin (16).
A securing pin which, in order to secure two chain connector shackles of a chain connector against becoming disengaged, can be inserted into an opening formed by the two chain connector shackles, comprising a base body with a through-hole, at least one spring ring, at least two balls, and a securing member inserted into the through-hole, wherein in a lateral surface of the base body an annular groove is provided, in which the at least one spring ring is inserted, wherein the annular groove is provided with two bore holes which are aligned with the through-hole and in which the balls rest, and wherein the at least one spring ring has at least one leg which extends in the longitudinal direction of the base body and which bends out of shape if the securing pin is inserted into the opening incorrectly.
A chain connector for connecting two chains formed of links, comprising a first chain connector shackle, a second chain connector shackle and a securing pin, the securing pin comprising a base body with a through-hole, at least one spring ring, at least two balls, and a securing member inserted into the through-hole, wherein in a lateral surface of the base body an annular groove is provided, in which the at least one spring ring is inserted, wherein the annular groove is provided with two bore holes which are aligned with the through-hole and in which the balls rest, and wherein the at least one spring ring has at least one leg which extends in the longitudinal direction of the base body and which bends out of shape if the securing pin is inserted into the opening incorrectly, wherein the two chain connector shackles positively engage each other and form an opening in which the securing pin is inserted.
A method for connecting two chains by means of a chain connector and for securing chain connector shackles of the chain connector against becoming disengaged by means of a securing pin, comprising the following steps:
