[0013] It should be understood that the specific embodiments described herein are merely illustrative of the present invention and are not intended to limit the present invention.

[0014] Reference Figures 1 to 9 An embodiment of the door lock connection structure of this utility model is proposed: A door lock connection structure includes a lock cylinder connection structure 1 and a positioning plate 2.

[0015] The door lock includes an inner lock seat 3, an outer lock seat 4, and a lock cylinder. The inner lock seat 3 is provided with an inner lock seat lock hole 31. Multiple inner lock seat connecting posts 32 are provided around the inner lock seat lock hole 31 on the inner side of the inner lock seat 3. Multiple limiting protrusions 33 are also provided on the inner side of the inner lock seat connecting posts 32.

[0016] The positioning plate 2 includes a first positioning plate and a second positioning plate. The first positioning plate and the second positioning plate are respectively provided with four positioning plate first connecting holes 21 at their four corners, which are adapted to the inner connecting post 32 of the inner lock seat. The positioning plate first connecting holes 21 and the inner connecting post 32 of the inner lock seat are connected by screws, so that the first positioning plate and the second positioning plate can be fixedly connected to the inner lock seat 3 respectively.

[0017] Both the first and second positioning plates have elliptical positioning grooves 23 between them. The positioning groove 23 of the first positioning plate is positioned slightly higher, while the positioning groove 23 of the second positioning plate is positioned slightly lower. The first and second positioning plates can respectively adapt to the positions of the two types of inner lock seat lock holes 31.

[0018] The first and second positioning plates each have four opposing second positioning plate connecting holes 22 on their upper and lower sides of the positioning plate positioning groove 23. The two second positioning plate connecting holes 22 at the top upper side and the two second positioning plate connecting holes 22 at the top lower side of the positioning plate positioning groove 23 form the first set of second positioning plate connecting holes 22. The two second positioning plate connecting holes 22 at the bottom upper side and the two second positioning plate connecting holes 22 at the bottom lower side of the positioning plate positioning groove 23 form the second set of second positioning plate connecting holes 22.
