KEY-OPERATED HANDLE KNOB ASSEMBLY HAVING HIGH COMPRESSIVE STRENGTH |
摘要 |
<p>A handle knob assembly comprises a knob shell and a lock retainer disposed within the knob shell. The lock retainer includes a hollow drum portion, a hollow neck part extending rearwardly from the drum portion and projecting out of a rear opening of the knob shell, a lock-receiving hole formed in the drum portion and aligned with a key hole of the knob shell, a plurality of annularly spaced apart and axially extending ribs that project radially from an outer periphery of the drum portion, and a ring extending around the ribs and having a distal peripheral end extending toward an inner surface of the knob shell. The construction as such saves the cost of materials and provides sufficient strength to resist radial compressive forces.</p> |
