Abstract
A handle locking structure includes a handle having a pivot portion pivotally connected to a sliding box, a buckle portion for hooking on a cabinet and a handle shaft, and a positioning structure including a base connected to the handle shaft, a positioning device mounted in the base and an elastic member placed on the positioning device. When the handle is hooked on the cabinet, a peripheral limiter of a head member of the positioning device is disengaged from a position-limiting notch of the base to reset the elastic member, so that the positioning device is automatically locked to the sliding box, avoiding vibration of the handle and improving the locking stability of the handle.
Claims12
A handle locking structure, comprising:
- a handle comprising a pivot portion pivotally connected to a sliding box, a buckle portion located at one side relative to said pivot portion for hooking on a cabinet and a handle shaft located at an opposite side relative to said pivot portion;
- and
- a positioning structure comprising a base connected to said handle shaft, a positioning device mounted in said base and an elastic member placed on said positioning device, said base comprising a perforation, an accommodation chamber with a larger outer diameter recessed on one end of said perforation and a position-limiting notch located on the peripheral wall of said accommodation chamber, said positioning device comprising a head member accommodated in said accommodation chamber and provided with a peripheral limiter for positioning in said position-limiting notch, a shank inserted through said perforation and connected with one end thereof to said head member, a stop block located at an opposite end of said shank for stopping against an upright lug of said cabinet and a fixing portion extended from said stop block opposite to said shank for positioning on said upright lug of said cabinet, said elastic member comprising an elastically compressible coil body mounted around said shank and two positioning means respectively located at two opposite ends of said elastically compressible coil body and respectively fastened to said base and said stop block;
- wherein when said buckle portion of said handle is unhooked from said cabinet, said fixing portion of said positioning device is disengaged from said upright lug of said cabinet, said elastically compressible coil body of said elastic member is twisted and elastically uncompressed;
- when said buckle portion of said handle is hooked on said cabinet, said fixing portion of said positioning device is positioned on said upright lug of said cabinet, said peripheral limiter of said head member is disengaged from said position-limiting notch of said base, and said elastically compressible coil body of said elastic member is untwisted and elastically compressed.
