European-standard C-slot concealed hinged top-hung casement hardware system

Abstract

Disclosed is an European-standard C-slot concealed hinged top-hung casement hardware system. The e European-standard C-slot concealed hinged top-hung casement hardware system comprises an European-standard slot transmission bar, a linkage rod, a connecting rod, a handle, a lock body, a connecting component, a lower corner connector, an upper corner connector, a lock seat, a multi-point lock and a crank rocker. One end of the European-standard slot transmission bar is connected with a lock body, and the other end of the European-standard slot transmission bar is connected with the connecting component; the connecting component is provided with a fastening point and connected with the lower corner connector through the fastening point; one end of the linkage rod is connected with the lock body, and the other end of the linkage rod is connected with the upper corner connector; the upper corner connector is provided with a fastening point and connected with the lock seat through the fastening point; the lock seat is connected with the transmission bar and the lock catch of the multi-point lock through the connecting rod; the inside of the multi-point lock is provided with a transmission block and a positioning block and connected with the crank rocker through the transmission block and the positioning block; the handle is connected with the lock body. The European-standard C-slot concealed hinged top-hung casement hardware system improves the anti-theft performance, enhances the air tightness, is concise and simple in appearance and capable of meeting the requirements on exterior wall decoration, simplifies mounting and debugging tools and improves the mounting efficiency.

Description

technical field [0001] The invention relates to a door and window hinge, in particular to a European standard C-notch concealed hinge hardware fitting with inward opening and inversion. Background technique [0002] Many existing doors and windows basically have hinges. Through the hinge connection, the doors and windows can rotate freely without noise, but many existing hinges are exposed on the surface of the profile, which affects the visual effect of the building, and is relatively easy to be broken and damaged; at the same time It is necessary to cut off the EPDM sealing strip at the hinge installation place before installing it. When the window is locked, the sealing performance of the EPDM strip at the hinge will be affected, and the proper performance of the strip cannot be achieved. The sealing effect reduces the airtightness and watertightness of the window as a whole. There are many installation and debugging tools, complicated procedures, low efficiency and high ...

[0002] Many existing doors and windows basically have hinges. Through the hinge connection, the doors and windows can rotate freely without noise, but many existing hinges are exposed on the surface of the profile, which affects the visual effect of the building, and is relatively easy to be broken and damaged; at the same time It is necessary to cut off the EPDM sealing strip at the hinge installation place before installing it. When the window is locked, the sealing performance of the EPDM strip at the hinge will be affected, and the proper performance of the strip cannot be achieved. The sealing effect reduces the overall airtightness and watertightness of the window. There are many installation and debugging tools, complicated procedures, low efficiency and high error rate.
