Door lock key cylinder cover mechanism
The invention relates to a hardware door lock fitting and provides a door lock key cylinder cover mechanism which adopts a reliable and fine part to realize hiding and protecting of the key cylinder. According to the scheme, a key cylinder cover hole is formed in a lock panel, a key cylinder cover is embedded into the key cylinder cover hole; two elastic sheets are matched with the two sides of the key cylinder respectively; a base is fixed in the lock panel; slide slots are formed in the two sides of the base for resisting against the two ends of an elastic sheet to generate certain pre-pressing force for resisting the key cylinder cover against the key cylinder cover hole. When the key cylinder cover is pressed, the key cylinder cover slides backwards to realize a function of quickly opening the key cylinder cover; when the key cylinder cover is re-pressed to move forwards, the key cylinder cover is automatically returned to the key cylinder cover through acting force of the elastic sheet.
