Mounting structure of safety door mounting piece

Abstract

The invention relates to the technical field of fixed connection of devices on door leaves, in particular to a mounting structure of a safety door mounting part. The mounting structure comprises a door panel with a mounting opening, a fixing frame which is arranged at the mounting opening of the door panel and concaves inwards towards the door leaf to form a mounting cavity, a first fixing piece which is fixedly connected with the mounting piece and is suitable for being placed into the mounting cavity through the mounting opening, and a locking piece which is movably arranged on the fixing frame and is relatively locked with the first fixing piece arranged in the mounting cavity through the movement parallel to the door panel. The first fixing piece fixedly connected with the mounting piece is relatively locked in the mounting cavity formed by enabling the fixing frame to concave inwards towards the door leaf through the locking piece, so that the safety door mounting piece is fixed,the locking piece and the first fixing piece are hidden in the mounting cavity of the fixing frame, no screw is exposed on the connecting surface, the connection mode is hidden and not liable to identify and disassemble, and the safety door mounting part can be independently fixed.

Description

technical field [0001] The invention relates to the technical field of fixed connection of devices on a door leaf, in particular to an installation structure of a safety door installation part. Background technique [0002] With the development of door lock technology and the improvement of people's living standards, door locks must not only meet people's safety needs, but the appearance of door locks has gradually become an important factor for people to choose door locks.
