Problems solved by technology

However, if the door handle is subjected to an external force when the push-pull module turns on the anti-cat eye function, the external force transmitted from the door handle to the push-pull module will easily cause stress damage to the internal structure of the push-pull module

Embodiment Construction

[0109] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and examples.

[0110] figure 1 It is a schematic diagram of a partial structure of a push-pull module in an embodiment of the present invention. figure 2 For such figure 1 Schematic diagram of the anti-peephole locking state of the push-pull module shown. Figure 3a to Figure 3c For such figure 1 Schematic diagram of the anti-peephole unlocking state of the push-pull module shown. See figure 1 , and combined with figure 2 as well as Figure 3a to Figure 3c , in this embodiment, the push-pull module may include a bottom box 10 , a push-pull rod 20 , a square shaft 40 , and an anti-cat eye switch dial 50 .

[0111] The push-pull rod 20 is mounted on the bottom box 10 in a push-pull manner. For example, the push-pull rod 20 may be arranged along the length dire...

Abstract

The invention discloses a push-pull module of a door lock. Based on the present invention, the push-pull stroke of the push-pull rod is selectively associated with any one of the two rotation directions of the square shaft through detachable assembly, thus providing a reversing function that adapts to different opening and closing directions of the door leaf; preventing cat's eyes The switch toggle block can realize the anti-rotation locking of the other body axis and the release of the degree of freedom of rotation by switching the position along the toggle stroke, so as to further provide the cat's eye prevention function on the basis of the phase change function. Moreover, the anti-cat-eye function can only rely on the cooperation of the anti-cat-eye switch block and the square shaft, and the number of components is small, which helps to reduce assembly costs and material costs, and reduces the failure probability of the anti-cat-eye function; the block-shaped anti-cat The support strength of the cat's eye switch block is strong, which is conducive to improving the anti-prying ability. In addition, the push-pull module can realize automatic return when the push-pull rod is not subjected to 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...
