Description
Technical Field
The invention relates to an anti-theft door assembly, in particular to a hidden anti-theft door anti-break device.
Background
The anti-theft door is called as an anti-theft safety door, and is used as a door for entering a household in general, and has anti-theft and safety performances. Burglary-resisting doors are generally protected from vandalism or improper opening by external personnel by means of a metal deck of the door body and various locks. When someone accesses, indoor people generally observe outdoor conditions through cat eyes. When communication is required, it is common practice to open a door seam. Thus, a certain potential safety hazard exists. From the opening of the door, the metal deck of the security door and the lock are in a failure state. If outside personnel break in forcefully, indoor personnel are difficult to ensure safety. The existing anti-break device is generally characterized in that a metal chain is arranged on a door frame, one end of the metal chain is fixed on the door frame, and the other side of the metal chain is provided with a lock catch. A lock hole part is arranged on the door leaf. The lock catch can freely enter and exit the lock hole part when the door is in a closed state. When the lock is needed, the lock catch is arranged in the lock hole, and when the door is opened, the lock catch slides in the sliding groove of the lock hole component, and at the moment, the lock catch cannot be taken down. Thus, when the door is opened, the door is controlled to be at an opening angle through the chain, so that people cannot break in, and the anti-break device is commonly used in hotel doors. But the firmness of the anti-break device is from the strength of the metal chain, the installation strength of the metal chain and the door frame, the installation strength of the lock hole part on the door leaf and the matching strength of the metal chain lock catch and the lock hole part. In fact, the strength of each part is not ideal, and the effect of preventing outsiders from intruding is not well achieved.
