DETAILED DESCRIPTION

[0022] Refer to the attached Figures 1 to 5 The installation structure of a split lock of the utility model is further described in detail.

[0023] A split lock installation structure includes an outer split ring 1 and an inner split ring 2; the inner split ring 2 includes an inner ring 21 and an outer ring 22 that match each other, and the inner ring 21 is installed on a door panel through a fastener 3;

[0024] The outer ring 22 includes an inner lining 221 and a decorative cover 222 wrapped around the outer side of the inner lining 221, wherein the inner lining 221 is fixedly connected to the decorative cover 222; a mounting hole 2211 for mounting the outer ring 22 is opened on the top wall of the inner lining 221, and the mounting hole 2211 is in a gourd shape, and the mounting hole 2211 includes a through hole portion 22111 at one end and a locking hole portion 22112 at the other end, and the through hole portion 22111 and the locking hole portion 22112 are connected to each other; wherein the aperture of the through hole portion 22111 is larger than the outer diameter of the head 31 of the fastener 3, so that the head 31 can smoothly pass through the through hole portion 22111, and the aperture of the locking hole portion 22112 is smaller than the outer diameter of the head 31 of the fastener 3, and at the same time is adapted to the fastener 3, so that the head 31 of the fastener 3 can smoothly enter the locking hole portion 22112 from the through hole portion 22111;

[0025] The head 31 of the fastener 3 passes through the top wall of the lining 221 through the perforated hole 22111, and the head 31 of the fastener 3 enters the locking hole 22112 through the perforated hole 22111 by rotating the outer ring 22. The head 31 of the fastener 3 cooperates with the locking hole 22112 to lock the outer ring 22 on the inner ring 21.

[0026] When installing the split lock, the inner ring 21 is installed on the door panel through the fastener 3 passing through the fixing hole 211, wherein the head 31 of the fastener 3 floats outside the fixing hole 211; then the mounting hole 2211 of the inner lining 221 of the outer ring 22 is aligned with the head 31 of the fastener 3, so that the head 31 passes through the top wall of the inner lining 221 from the penetration hole portion 22111, and then the outer ring 22 is rotated to make the head 31 of the fastener 3 enter the locking hole portion 22112 from the penetration hole portion 22111, and the head 31 of the fastener 3 cooperates with the locking hole portion 22112 to lock the outer ring 22 on the inner ring 21; thus, the installation and fixation of the outer ring 22 on the inner ring 21 is completed; the operation is simple and convenient, and no additional fixation by the top screw is required, thereby improving the installation efficiency of the door lock; wherein the fastener 3 used to lock the outer ring 22 is wrapped in the decorative cover 222, thereby improving the aesthetics of the door lock and preventing the fastener 3 exposed to the outside from rusting and corrosion.
