Locking mechanism for load analyzer

摘要

The invention provides a locking mechanism having a catch with a first recess including a lateral wall that extends generally perpendicular to an applied load and an inclined portion that is inclined relative to the lateral wall. The locking mechanism can also include a guide block having a second recess. The guide block can further include a lock wedge that is slidably disposed within the second recess having a first inclined surface that corresponds to the inclined portion of the catch, a second inclined surface, and a contact surface. The guide block can also include a jam wedge that is slidably disposed within the second recess having an inclined surface corresponding to the second inclined surface of the lock wedge. During operation, the lock wedge is urged towards the catch so that a portion of the lock wedge is disposed within the recess of the catch so that the first inclined surface of the lock wedge is in contact with the inclined portion of the catch and the contact surface of the lock wedge is in contact with the lateral wall of the catch. Additionally, the jam wedge can be urged towards the catch so that the inclined surface of the jam wedge is in contact with the second inclined surface of the lock wedge.
