Abstract

Door lock shielding cover, which includes a shielding cover body, an attraction member, and blocking portions. The shielding cover body is configured to be movably installed onto a lock panel of a smart door lock. The attraction member is installed on a side of the shielding cover body adjacent to the lock panel of the smart door lock. A plurality of through holes is defined in the attraction member. The blocking portions correspond to the through holes in a one-to-one manner. Each of the blocking portions is fixed to the shielding cover body through a connecting portion that penetrates the through hole, thereby fixing the attraction member to the shielding cover body. The fixing between the shielding cover body and the attraction member in the door lock shielding cover is firm and durable.

First claim

What is claimed is:

1. A door lock shielding cover comprising:
a shielding cover body configured to be movably installed onto a lock panel of a smart door lock;
an attraction member installed on a side of the shielding cover body adjacent to the lock panel of the smart door lock, and configured to attract the shielding cover body to the lock panel of the smart door lock, a plurality of through holes being defined in the attraction member;
blocking portions corresponding to the through holes in a one-to-one manner, each of the blocking portions being fixed to the shielding cover body through a connecting portion that penetrates the through hole, thereby fixing the attraction member to the shielding cover body.

2. The door lock shielding cover of claim 1 , wherein the shielding cover body is made of a plastic material; the shielding cover body, the connecting portion, and the blocking portion are integrated together as one piece.

3. The door lock shielding cover of claim 2 , wherein the through holes are counterbores, and a diameter of an end of the counterbores adjacent to the shielding cover body is smaller than a diameter of another end of the counterbores away from the shielding cover body; the blocking portions are located at the end of the counterbores away from the shielding cover body.

4. The door lock shielding cover of claim 1 , further comprising a screw column, wherein the shielding cover body is movably installed on the lock panel of the smart door lock through the screw column.

5. The door lock shielding cover of claim 4 , wherein the screw column is located on the shielding cover body and integrated with the shielding cover body as one piece.

6. The door lock shielding cover of claim 5 , wherein the attraction member is located beside the screw column; a portion of the shielding cover body corresponding to the attraction member is provided with a recess, the attraction member is disposed in the recess; and a surface of the attraction member away from a bottom surface of the recess is flush with a surface of the shielding cover body facing the lock panel.

7. The door lock shielding cover of claim 5 , wherein the attraction member is provided with one through hole for the screw column to pass through; the attraction member covers a surface of the shielding cover body facing the lock panel; a surface of the attraction member away from the shielding cover body is a flat surface.

8. The door lock shielding cover of claim 5 , wherein the attraction member is located beside the screw column, and a surface of the attraction member facing the lock panel is higher than a surface of the shielding cover body facing the lock panel.

9. The door lock shielding cover of claim 5 , wherein the attraction member is provided with one through hole for the screw column to pass through; the attraction member covers a surface of the shielding cover body facing the lock panel; a portion, located at one side of the screw column, of a surface of the attraction member away from the shielding cover body is lower than another portion, located at another side of the screw column, of the surface of the attraction member away from the shielding cover body.

10. The door lock shielding cover of claim 4 , wherein the screw column is located on the attraction member and located at a side of the attraction member away from the shielding cover body; the screw column is integrated with the attraction member as one piece.

11. The door lock shielding cover of claim 10 , wherein an end of the attraction member having the screw column located thereon is away from an edge of the shielding cover body; a portion of the shielding cover body corresponding to the attraction member is provided with a recess; the attraction member is disposed in the recess; a surface of the attraction member away from a bottom surface of the recess is flush with a surface of the shielding cover body facing the lock panel.

12. The door lock shielding cover of claim 10 , wherein the attraction member covers a surface of the shielding cover body facing the lock panel; except a portion with the screw column, a surface of the attraction member away from the shielding cover body is a flat surface.

13. The door lock shielding cover of claim 10 , wherein an end of the attraction member having the screw column located thereon is away from an edge of the shielding cover body; and a surface of the attraction member facing the lock panel is higher than a surface of the shielding cover body facing the lock panel.

14. The door lock shielding cover of claim 10 , wherein the attraction member covers a surface of the shielding cover body facing the lock panel; a portion, located at one side of the screw column, of a surface of the attraction member away from the shielding cover body is lower than another portion, located at another side of the screw column, of a surface of the attraction member away from the shielding cover body.

15. The door lock shielding cover of claim 1 , wherein the attraction member is capable of being attracted to the shielding cover body through magnetic attraction.
