Abstract:
1. A unlocking mechanism for a retention module holder which has a fastening stand for holding a radiator, and a locking member having a first end that is pivotally engaged with the fastening stand and a latch hook on a second end opposing the first end, the second end being latchable to retain the radiator when the locking member is at a latched position, the second end being un-latchable to allow the locking member to separate from the radiator at a release position, the unlocking mechanism comprising: a latch ledge located on one side of the fastening stand opposite to the first end of the locking member, and having an anchor hole disposed in registration with the latch hook when the locking member is at the latched position; a beam movably coupled on the one side of the fastening stand, and having an actuating part, and a protruding part opposing the actuating part, the protruding part being engagable with the latch hook when the locking member is at the latched position; and a spring coupled on one side of the beam remote from the protruding part, and which urges the protruding part into engagement with the anchor hole; wherein when the actuating part is moved by external forces, the spring is deformed and the protruding part is moved to allow the protruding part to disengage with the anchor hole and the latch hook, to allow the locking member to separate from the radiator at the release position, and when the radiator is to be retained, the spring urges the protruding part to engage with the latch hook and the anchor hole, so that the locking member is latched at the latched position and the radiator is retained; and wherein the locking member is slightly deformed at the latched position and has a deformation restoring force to allow the locking member to escape the latched position and reach the release position when the latch hook is disengaged with the protruding part.
