Abstract
This utility model discloses a blocking device for preventing the bolt in a door lock from extending out of the lock. The bolt's extension and retraction direction is a first direction. The device includes: a fixing base, which can be fixed to the door body, and has an opening extending through the fixing base along the first direction. The projection of the bolt along the first direction is within the outline of the opening. A sliding groove is provided on the side wall of the opening, and the extension direction of the sliding groove is perpendicular to the first direction. A sliding plate is provided in the sliding groove and can slide between a first position and a second position along the sliding groove. When the sliding plate is in the first position, the projection of the bolt along the first direction is at least partially within the outline of the sliding plate. When the sliding plate is in the second position, the projection of the bolt along the first direction is outside the outline of the sliding plate. This utility model can be directly installed on a door to prevent the bolt from extending. It is simple to operate, highly adaptable, and does not damage the original lock body's structure and function.
