Door lock structure

Abstract

The invention provides a door lock structure which comprises a first door handle, a second door handle and a lock body, wherein the lock body is arranged between the first door handle and the second door handle. The first door handle and the second door handle respectively control the expansion of the lock body and a lock tongue. A fixed turning block, a handle seat, a retainer, a spring and a control rod connected with a second handle knob are arranged in the first handle, and the control rod controls the turning block to turn. The spring is arranged in the handle seat and abuts against the retainer to reset, and the retainer is arranged in the handle seat and one end of the retainer extends out of the handle seat to abut against the turning block. A limiting groove matched with a limiting bulge of the retainer is formed in the handle seat. The retainer moves along the spring direction along with the turning of the turning block, so that the limiting bulge enters into the limiting groove or leaves the limiting groove. When the limiting bulge enters into the limiting groove, the first door handle and the second door handle are locked. When the limiting bulge leaves the limiting groove, the first door handle and the second door handle are unlocked. The volume of the lock body is reduced, the structure is simple and practical, and the door lock structure is suitable for bathroomsand doors without needing prevention of burglary.
