The working method of the door lock self-locking structure adopts the door lock self-locking structure as in the embodiment 1, and comprises the following steps:
S10, pulling a handle 1 in the door to close the door, pulling a sliding button 12 by using a finger to drive a rotation driving piece 13 to synchronously slide, and meshing a meshing piece of the rotation driving piece 13 with a gear of a rotation piece 14 to drive a rotating shaft 15 to synchronously rotate;
And S20, under the guiding action of the guide piece 31 and the symmetrical guide piece 32, when the arc-shaped protruding blocks 342 pass through the protruding parts 312 of the guide piece 31, the whole locking piece moves towards the direction close to the connecting shell 2, and simultaneously under the limiting action when the limiting rod 373 and the positioning hole 38 are inserted, the linear moving piece 37 cannot rotate along with the rotating shaft 15 and is inserted and matched with the limiting groove 21 in the moving process, so that the function of limiting the rotation and self locking of the door outer handle 3 is realized.
In summary, the working method of the present invention is mainly based on the structure of the door lock self-locking structure, when a user closes the door, the user can slide the sliding button 12 of the handle 1 in the door by hand, under the micro rotation of the rotating shaft 15, that is, the transmission effect, the guiding effect of the guiding element 31 and the symmetrical guiding element 32 is utilized to make the locking element perform the specific fluctuation motion, and meanwhile, the linear moving element 37 moves towards the limiting groove 21 and performs the insertion fit under the limiting effect, thereby realizing the door lock self-locking function, and therefore, the present invention has the advantages of simple operation and difficult forgetting.
The embodiments of the present invention are not limited thereto, and the present invention may be modified, substituted or combined in various other forms without departing from the basic technical spirit of the present invention, which falls within the scope of the claims, according to the above-described aspects of the present invention, using the general knowledge and conventional means of the art.
