Problems solved by technology

However, due to reasons such as the frequent rotation of the spherical handle 1 and the thermal expansion and contraction of the door panels, the outer adjustment ring 2 is easy to loosen due to the fixing method of the spherical handle 1, and the spherical handle 1 is prone to loosening. Causes damage to the entire ball lock

Abstract

The invention provides a fixing structure of a knob of a door lock. The fixing quality of the knob of the door lock can be improved and the service life of the knob can be prolonged by means of the fixing structure. The fixing structure comprises the knob and a knob connection portion; the knob connection portion is connected with an outer adjusting ring and an inner fixing ring in sequence from outside to inside; a threaded connection barrel is arranged on the inner circle of the inner fixing ring; and the inner circle of the outer adjusting ring is movably connected with the threaded connection barrel. The fixing structure is characterized in that a reinforcing nut is further arranged between the outer adjusting ring and the inner fixing ring, and the reinforcing nut is movably connectedwith the threaded connection barrel. By additionally arranging the reinforcing nut between the inner side of the outer adjusting ring and the inner fixing ring, the reinforcing nut plays a major rolein fixing, while the outer adjusting ring matches the reinforcing nut to relieve thread connection looseness caused when the knob bears non-rotating torque, the fixing quality of the knob of the doorlock can be improved, and the service life of the door lock with the knob is prolonged.

Description

technical field [0001] The invention relates to the technical field of door locks, in particular to a fixing structure for a handle of a spherical door lock. Background technique [0002] The spherical door lock is a very commonly used indoor door lock. The fixed structure of the door lock handle of the spherical door lock is generally as follows: figure 1 As shown: the door panel is clamped by the outer adjusting ring 2 and the inner fixing ring 3 on the connection part 11 of the spherical handle 1, and the inner fixing ring 3 is fixed through the door panel and the outer adjusting ring 2 through the threaded connection cylinder 31. When installing, The inner fixing ring 3 is fixed in the door panel by screws, and then the connecting part 11 of the spherical handle 1 passes through the threaded connection cylinder 31 to be connected with the lock cylinder, and then the outer adjusting ring 2 is pressed against the door panel by rotating the outer adjusting ring 2 to comple...
