Lock guard plate and lock assembly structure

Abstract

This invention provides a lock guard plate, comprising: a guard plate that is slightly annular and axially fitted onto the base plate of a lock; the guard plate has an annular portion at one end opposite the base plate, and at least one locking element protrudes from the outer edge of the annular portion; thereby, the guard plate is used to correspondingly extend into the door hole of the door leaf, and is locked into the door hole by the locking element, thereby improving the stability of the lock when positioned in the door hole and making it less prone to shaking under force; furthermore, by configuring a fixing component on the fixing post of the lock, and having a corresponding fixing element recessed on the inner edge of the annular portion, the guard plate can be pressed against by the fixing component of the fixing post when the fixing post is configured, and can be axially abutted against the base plate, thereby improving the stability of the guard plate when positioned between the base plate and the base plate; through this configuration, all components of this invention can be stably configured, and it is not prone to loosening or shaking under force, thereby improving the overall stability and quality of this invention, and ensuring the durability of each component.

4. The lock guard plate as described in claim 3, wherein, The guide portion and the latching portion are arranged in a sheet-like shape.

5. The lock guard plate as described in claim 3, wherein, The guard plate is further provided with a groove corresponding to the outer contour of the latching element at the corresponding location of the latching element.

6. The lock guard plate as described in any one of claims 1 to 5, wherein, The lock is further fixed at one end of the base plate with at least one fixing post, the fixing post having a fixing component; and the inner edge of the circumferential part is recessed with a fixing element corresponding to the fixing component, so that the guard plate is axially positioned on the fixing post and the guard plate abuts against the base plate axially.

7. The lock guard plate as described in claim 6, wherein, The fixing component is a recessed groove in the fixing post, and the fastening element is correspondingly abutted against the axial wall surface of the fixing component.

8. The lock guard plate as described in claim 7, wherein, The fixing element is arranged in a sheet-like form.

9. The lock guard plate as described in claim 7, wherein, The fastening element is radially recessed with a corresponding slot, and the slot abuts against the fixing component.

10. A lock assembly structure suitable for fixing to a door hole of a door panel, the lock assembly structure comprising: a lock having a base plate and a handle at one end of the base plate; a guard plate correspondingly disposed at one end of the base plate opposite to the handle, the guard plate being slightly annular and having an annular connection portion at one end opposite to the base plate, the outer edge of the annular connection portion having at least one locking element protruding therefrom, the guard plate being suitable for at least partially inserting into the door hole to fix the lock to the door panel.

11. The lock assembly structure as described in claim 10, wherein, The guard plate further includes a receiving portion that abuts against the base plate. The circumferential portion extends axially from the receiving portion, and the outer diameter of the circumferential portion is smaller than the outer diameter of the receiving portion.

12. The lock assembly structure as described in claim 10, wherein, The latching element is elastically arranged and includes a guide portion and a latching portion; the guide portion is inclined and located at one end relative to the base plate; and the latching portion is correspondingly connected to the guide portion at the end corresponding to the base plate.

13. The lock assembly structure as described in claim 12, wherein, The guide portion and the latching portion are arranged in a sheet-like shape.

14. The lock assembly structure as described in claim 12, wherein, The guard plate is further provided with a groove corresponding to the outer contour of the latching element at the corresponding location of the latching element.

15. The lock assembly structure as described in any one of claims 10 to 14, wherein, The lock is further fixed at one end of the base plate with at least one fixing post, the fixing post having a fixing component; and the inner edge of the circumferential part is recessed with a fixing element corresponding to the fixing component, so that the guard plate is axially positioned on the fixing post and the guard plate abuts against the base plate axially.

16. The lock assembly structure as described in claim 15, wherein, The fixing component is a recessed groove in the fixing post, and the fastening element is correspondingly abutted against the axial wall surface of the fixing component.

17. The lock assembly structure as described in claim 16, wherein, The fixing element is arranged in a sheet-like form.
