Embodiment Construction

[0015] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0016] Such as figure 1 , The door lock backing plate of the present invention includes a base plate 1, a lock shaft sleeve hole 2, a backing plate fixing screw hole 3, a lock head fixing screw hole 4, and a positioning protrusion 5. The backing plate of the present invention enables normal door locks to be installed and used normally, and cooperates with the lock head and the door plate to increase the thickness of the door plate. The size, position, quantity and size of the fixing screw holes on the door lock respectively determine the length and width of the bottom plate 1, the position and size of the lock shaft sleeve hole 2, the position, quantity and size of the lock head fixing screw hole 4, and then install the door Before locking, place the door lock backing plate on the confirmed position on the door panel, and fix the door lock ...

Abstract

The invention relates to a door lock base plate. The door lock base plate comprises a bottom plate, a lock shaft sleeve hole, base plate fixing screw holes, lock head fixing screw holes and positioning protrusions, wherein the bottom plate is a rectangular metal plate, the lock shaft sleeve hole is formed in the symmetrical center of the bottom plate, the diameter of the lock shaft sleeve hole is larger than that of a lock shaft, the metal plate is provided with the four base plate fixing screw holes which are distributed in a square mode, the center of the square coincides with the symmetrical center of the metal plate, the four lock head fixing screw holes which are distributed in a rectangular mode are parallel to the base plate fixing screw holes, the symmetrical center of the rectangle coincides with the symmetrical center of the bottom plate, and the peripheral edges of the bottom plate are provided with the positioning protrusions which are symmetrically distributed. Due to the fact that a metal piece is additionally arranged between a lock head and a door plank, the thickness of the door plank is indirectly increased, all door locks can be normally installed and used even under the situation that the door plank is thin, the problem that the universality of a traditional door lock and the door plank is solved, and the door lock base plate has high universality and practicality.

Description
