Description
Technical Field
The utility model belongs to the technical field of door leaves, and particularly relates to an anti-insertion and inward-opening anti-theft door.
Background
When the existing anti-theft door (including a fireproof entrance door) is opened inwards, if the door is not locked reversely, the lock can be inserted by a card, so that potential safety hazards exist.
Therefore, there is a need to develop a new anti-insert, anti-opening and anti-theft door.
Disclosure of Invention
The utility model aims to provide an anti-insertion inner-opening anti-theft door which can realize the anti-insertion function of an inner-opening door.
The utility model relates to an anti-insertion internally-opened anti-theft door, which comprises a door frame and a door leaf, wherein the hinge side of the door leaf is hinged with the door frame, and the lock side of the door leaf is provided with an inclined tongue which is matched with an inclined tongue hole arranged on the lock side of the door frame; the outer side of the position corresponding to the latch bolt on the door stop edge surface of the door frame is provided with an anti-insertion piece; the anti-inserting piece is provided with an anti-inserting slot with an outward opening.
Optionally, the inserting-proof piece is installed on the door stop edge surface of the door frame through a latch bolt protecting block; the latch bolt protecting block is fixed on the door stop edge surface of the door frame through a screw; the inclined tongue protecting block is provided with a through hole for the inclined tongue to pass through at the position corresponding to the inclined tongue hole.
Optionally, the anti-insertion piece is Z-shaped and comprises a first surface, a second surface and a third surface which are sequentially connected, the first surface and the second surface are connected to form a clamping groove, and the second surface and the third surface are connected to form an anti-insertion groove; the inserting-preventing piece is clamped on the oblique tongue protecting block through a clamping groove.
Optionally, an included angle between the third face and the second face of the insert prevention piece is less than 90 °.
The utility model has the following advantages: the inserting-preventing groove can effectively prevent the card from being inserted into the gap between the door frame and the door leaf, and the third surface of the inserting-preventing piece is an inclined surface, so that the card is naturally inserted into the groove of the inserting-preventing piece, and the oblique tongue on the mechanical lock body is protected from being inserted by the card, thereby realizing the inserting-preventing function of the inward opening door.
Drawings
FIG. 1 is a schematic structural diagram of the present embodiment;
in the figure: 1. the anti-insertion piece comprises a first face, a second face, a third face, a second face, a latch bolt protection block, a door frame, a latch bolt, a door leaf and a clamping piece, and the latch bolt is 2, 3, 4 and 5.
Detailed Description
The utility model will be further explained with reference to the drawings.
