Detailed Description

A novel door lock handle of the present invention will be described in further detail with reference to fig. 1 to 6.

A novel door lock handle comprises a handle body 1, wherein the handle body 1 is provided with an inserting hole 11 for inserting a square shaft sleeve 2; the end face of the square shaft sleeve 2 facing the plug hole 11 is an inclined plane 21 with a certain inclination angle;

the inserting hole 11 is internally provided with a locking component 3 for locking the square shaft 5, the locking component 3 comprises a locking plate 31 and a locking spring 32 which are arranged on the inclined plane 21, and the locking plate 31 is provided with a locking hole 311;

one end of the locking spring 32 is abutted against the locking plate 31, and the other end of the locking spring is abutted against the handle body 1; so that the locking plate 31 is obliquely arranged along the inclined surface 21 of the square shaft sleeve 2;

when the door lock is installed, after the square shaft 5 is inserted into the square shaft sleeve 2 and the locking hole 311 of the locking plate 31, the locking plate 31 is obliquely arranged along the inclined plane 21 of the square shaft sleeve 2 again from a horizontal state under the action of the locking spring 32, so that the inner side wall of the locking hole 311 is always abutted against the outer side wall of the square shaft 5 to lock the square shaft 5; the traditional door lock is replaced, and a screw is screwed in from the outside of the handle to lock the square shaft 5; the door lock is convenient to install and stable and firm in structure.
