The present invention provides a door lock structure, wherein the first shell (21) and the second shell (22) are matched and then locked with each other.

The present invention provides a door lock structure, wherein the opening and closing device (40), the pivot seat (51) and the lever (52) of the two door handle sets are inverted to each other (please compare Fig. 7 and Fig. 8 at the same time). ), so that the two door handle sets can be installed on the door panel (10) in the form of one pulling and one pressing.

The present invention provides a door lock structure, wherein the two door handle assemblies are vertically installed on the door panel (10) (please also view it as shown in Figure 1).

The present invention provides a door lock structure, wherein the two door handle assemblies are horizontally installed on the door panel (10) (please also view it as shown in FIG. 12).

The present invention provides a door lock structure, wherein a second spring (48) can also be supported between the second lifting plate (42) and the first casing (21) (please also see it as shown in FIG. 13) , in order to increase the force of its active reset by the installation of the second spring (48).

The present invention provides a door lock structure, wherein the first lifting plate (41) and the second lifting plate (42) are combined with each other through the insertion of a bolt (49).

The present invention provides a door lock structure, wherein the pivot seat (51) and the lever (52) are fabricated separately, and then assembled in a locking manner (please also see Fig. 2).

The present invention provides a door lock structure, wherein the pivot seat (51) and the lever (52) are formed in one piece (please also see Fig. 16).

In actual use, the handle (50) is pulled or pressed according to the rotation direction of the door panel (10) after it is opened (please see it as shown in Figure 9 at the same time), so as to use the handle (50) Pull or press to complete the opening of the door panel (10), that is, after the handle (50) is pulled (the same is true for pressing, but the action direction is opposite), the pivot seat (51) will drive the dial The rod (52) goes up (please see it as shown in Figure 10 at the same time), so that the second lifting plate (42) can be pryed by the lever (52), thereby driving the first lifting plate (52). 41) Translation, and because the first barb part (412) and the second barb part (422) have a height difference, in the process of translation, the first barb part (412) The contact with the first extension arm (432) drives the connecting sleeve (30) to rotate through the first control board (43) (the rotation angle of the first control board 43 is below 45 degrees). When the rotation of the first segment is still not enough to completely drive the lock tongue (12) to retract, the second barb (422) and the second extension arm (442) will come into continuous contact with each other. The second control board (44) drives the connecting sleeve (30) to rotate in the second stage (the rotation angle of the second control board 44 is between 20 degrees and 80 degrees), using the coverage of the two-stage rotation angle , the locking tongue (12) can be fully driven to retract, so as to further open the door panel (10), and the resetting member (443) is used to pass through the reset member ( 46) At the same time, it is forced against the first spring (47) for compression (please see it as shown in Figure 11 at the same time), and the opening and closing device (40) can also have the ability to release the handle (50). Afterwards, the effect of active reset is achieved.
