Abstract

The invention discloses a push-pull module of a door lock. Based on the push-pull module, the push-pull stroke of a push-pull rod is selectively associated with any one of two rotating directions of asquare shaft through detachable assembly, so that a reversing function adaptive to different opening and closing directions of a door leaf can be provided; and through a cat eye protection switch block, rotation stopping, clamping and rotational degree-of-freedom release of the square shaft can be achieved through position switching along the shifting stroke, so that the cat eye protection function is further provided on the basis of providing a phase change function. Moreover, the cat eye protection function can only depend on cooperation of the cat eye preventing switch block and the squareshaft, and the number of parts is low; the assembly cost and the material cost can be reduced, and the failure probability of the cat eye preventing function is reduced; and the blocky cat eye protection switch block is high in supporting strength, and the improvement of the prying prevention capacity is benefited. In addition, automatic return of the push-pull module can be achieved under the condition that the push-pull rod does not bear push-pull external force.

Description

technical field [0001] The invention relates to door lock technology, in particular to a push-pull module of a door lock. Background technique [0002] The push-pull module of the door lock can convert the push-pull operation of the door handle into the locking and unlocking of the lock cylinder. For the door leaf with peephole, there are often unscrupulous personnel to forcibly destroy and remove the peephole on the outdoor side of the door leaf, and penetrate the pry bar through the peephole mounting hole of the door leaf to the indoor side, so as to use the pry bar to pry the door handle on the indoor side Perform push-pull operation to realize illegal unlocking of the door lock. [0003] In order to avoid the above-mentioned illegal unlocking through cat's eyes, the push-pull module can provide the function of preventing cat's eyes. When the anti-cat eye function is turned on, the push-pull module can lock the door handle, so as to generate a locking force against pryi...
