LOCKING PIN FOR USE WITH LOCKING SPRING OF LOCKING MECHANICAL TENSIONER AND MECHANICAL TENSIONER

WIPO Patent Application WO/2019/061464

A1

A locking pin (3) for use with a spring (2) of a locking mechanical tensioner and a mechanical tensioner provided with the locking pin (3); the mechanical tensioner comprises a tensioner main body (1) and the spring (2) which is mounted on the tensioner main body (1), a fixed spring leg (22) of the spring (2) being fixedly mounted on the tensioner main body (1); the locking pin (3) comprises: an insertion portion (38), which is used for being inserted into a pin hole (12) of the tensioner main body (1) so as to mount the locking pin (3) onto the tensioner main body (1); a stopping portion (39), which is used for stopping a free spring leg (23) of the spring (2), thereby maintaining the spring in a compressed state; in a state wherein the locking pin (3) locks the spring (2), the insertion portion (38) and the stopping portion (39) are spaced apart in the compression and expansion direction of the free spring leg (23). The mechanical tensioner provided with the locking pin (3) reduces the material requirements for the spring (2) and is easy to assemble; meanwhile, the stress at the pin hole (12) is low, reducing the risk of failure.
