Detailed Description

The quick mounting structure of the decorative cover of the split lock of the present utility model will be described in further detail with reference to fig. 1 to 4.

As shown in fig. 1 and 2, a quick mounting structure for a decorative cover of a split lock comprises a base 1 and a decorative cover 2, wherein the base 1 is provided with screw holes 11 for mounting and fixing the base 1, the number of the screw holes 11 is usually two, and the screw holes 11 are circumferentially arranged at 180 degrees intervals, and when the split lock is mounted, the base 1 is mounted and fixed at a required position of a door body through the screw holes 11 and is matched with a corresponding lock body

As can be seen from fig. 3, one or more than one recess 12 is provided at the edge of the base 1, wherein the recess 12 is punched towards the decorative cover 2, so that the recess 12 is recessed towards the decorative cover 2, and thus the recess 12 does not interfere with the door body when the base 1 is mounted on the door body. A clamping notch 13 communicated with the concave part 12 is formed at one side of the concave part, and the clamping notch 13 can be formed by stamping; as can be seen from fig. 4, the side wall of the decorative cover 2 is provided with one or more clamping parts 21; when the split lock is installed, the decorative cover 2 is aligned with the base 1, the clamping parts 21 are in one-to-one correspondence with the concave parts 12, the clamping parts 21 are arranged in the concave parts 12 through the clamping cut 13, and then the decorative cover 2 is rotated, so that the clamping parts 21 are rotated to enter the other side edge of the concave parts 12, the clamping parts 21 are matched with the concave parts 12, the decorative cover 2 is quickly installed with the base 1, compared with the existing installation mode, the decorative cover 2 is prevented from being independently fixed through screws, the problem that the screws for the decorative cover 2 are exposed is avoided, meanwhile, the installation flow and the installation time are also greatly shortened, the installation difficulty of the split lock is reduced, and the split lock is also suitable for being automatically installed by common consumers.

In order to make the fitting between the decorative cover 2 and the base 1 more firm and stable, the number of the concave portions 12 is generally set to two, and the concave portions are circumferentially arranged at 180 ° intervals, so that the decorative cover 2 can be clamped on the base 1 at both front and rear positions, and firm and stable installation is provided.

Wherein set up spacing protruding muscle 14 in the side that recess 12 kept away from card income incision 13, spacing protruding muscle 14 forms with the side of recess 12 and clamping portion 21 matched with spacing draw-in groove, and when clamping portion 21 rotatory entering into the other side of recess 12 like this, clamping portion 21 will jump spacing protruding muscle 14 and arrange spacing draw-in groove in, restrict clamping portion 21 and fix on recess 12, avoid clamping portion 21 to remove in recess 12, also avoid clamping portion 21 unexpected to come out from clamping income incision 13 rotation and take place unexpected droing.
