Detailed Description

The following description of the embodiments of the present utility model will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present utility model, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.

Referring to the drawings, the present embodiment provides a safety door lock, which includes a main body 1 with an iron sheet structure, an extension portion 2 is fixedly mounted at the front end of the main body 1, and the extension portion 2 is made of the same material as the main body 1 and is located on the same plane as the main body 1. A right angle gap is formed between the underside of the extension 2 and the body 1, as shown in figure 1.

The front end of the main body 1 is inserted into the locking part between the door plate and the door frame, the extension part 2 is positioned between the lock tongue and the lock catch of the lock, the contact surface between the extension part and the door plate and the door frame is increased, the whole main body 1 is more stable when in use, and the right-angle structure is just attached to the locking notch of the door frame.

The protruding block 3 protruding outwards is fixedly arranged at the edge of the right-angle structure, and the protruding block 3 is of a cuboid sheet-shaped structure, as shown in fig. 1. The protruding blocks 3 are arranged on the horizontal edge and the vertical edge of the direct structure, and the extension lines of the two protruding blocks 3 are arranged at right angles.

As shown in fig. 2, two protruding blocks 3 are respectively clamped at the upper end edge and the edge close to the inner side of the door frame locking notch and extend into the locking notch, so that the main body 1 is connected with the locking notch, and after the upper door is closed, the main body 1 is connected with the locking notch under the extrusion force of the door and the door frame.

Because the two lugs 3 are arranged at right angles, when the door lock is used, the two lugs 3 are only required to be attached to the door frame locking notch, and the door lock with different sizes can be adapted.
