Problems solved by technology

The lock cylinder cover of this invention adopts a sliding structure, which realizes that when the user needs to use a spare mechanical lock cylinder to unlock, he only needs to press the button at the end of the lock housing, which is quite convenient and reliable, and this scheme is different from the original lock housing The perfect combination keeps the lock case intact and beautiful; but in this invention, the lock cylinder cover is set to occupy a larger area of ​​half of the lock case. Compared with the smaller lock cylinder, the lock cylinder cover is quite large, resulting in waste of materials. And the structure of opening the lock cylinder cover is complicated, and the use and maintenance costs are relatively high

Abstract

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.

Description

technical field [0001] The invention relates to a hardware door lock accessory, in particular to a lock core cover part of a door lock. Background technique [0002] At present, the door lock cylinder cover structures widely used in the market include an embedded lock cylinder cover and a sliding lock cylinder cover. A lock cylinder cover mechanism as disclosed in CN104314365A: a lock case, a cover plate ejection assembly, a push rod assembly and a cover plate are provided, and the cover plate ejection assembly is provided with a push plate, a bottom plate, and a spring A and a top post; the push rod assembly is provided with a button, a push rod, spring B and C-shaped circlip; the cover plate is provided with a decorative sheet and a buckle plate, and the two are screwed together. The pinch plate is hooked on the push plate by a hook. Press the button and the push rod drives the push plate to overcome the elastic force of spring B to generate a displacement, so that the bu...
