Description

Door lock core lid mechanism

Technical field

The utility model relates to a kind of five metals door lock fittings, especially the Lock cylinder cover parts of door lock.

Background technology

At present, the door lock core cap structure that market extensively uses has inset type Lock cylinder cover, also has the Lock cylinder cover of slidingtype.A kind of Lock cylinder cover mechanism disclosed in CN104314365A: establish a lock housing, a cover plate ejection assembly, a push-rod assembly and a cover plate, described cover plate ejection assembly establishes a push pedal, a base plate, spring A and fore-set; Described push-rod assembly establishes a button, a push rod, spring B and C type jump ring; Described cover plate establishes a cosmetic sheet and a buckle, and both are fixed at together.Buckle by a snap fit hooking, is pressed the button push rod and drives push pedal to overcome the elastic force generation displacement of spring B, the buckle on buckle and push pedal are departed from, can be released by cover plate under the active force of spring A by fore-set in push pedal.The Lock cylinder cover of this invention have employed sliding structure, achieves: when user needs to use stand-by machine lock core to unblank, only need press the button of lock housing end, quite convenient, reliable, and this programme and former lock housing perfect adaptation, maintain lock housing complete, attractive in appearance; But Lock cylinder cover is set to the larger area occupying lock housing half by this invention, for less lock core, Lock cylinder cover seems quite large, causes waste of material, and the complex structure of opened lock core cap, operation and maintenance cost is higher.

Summary of the invention

The purpose of this utility model is the deficiency overcoming existing Lock cylinder cover, provides a kind of door lock core lid mechanism, adopts reliable, meticulous parts to realize the hidden of lock core and protection.Its scheme is: in lock panel, establish a lock core cap bore, and lock core cap bore one end is provided with block fixed leg, and the other end is provided with limited block, and lock core cap bore both sides are all provided with gib block and base fixed leg, and gib block is provided with avoiding hollow groove; If a Lock cylinder cover embeds in lock core cap bore, Lock cylinder cover dual-side is provided with guide pad and coordinates slidably with the gib block of lock core cap bore both sides, be provided with locating piece and protrude from guide pad and in the avoiding hollow groove that can snap on gib block, with the relative position of fixed lock core lid and lock core cap bore; On rear side of guide pad, middle part is provided with fixed leg, two ends are provided with and compress rib; If two shell fragments coordinate with the guide pad of Lock cylinder cover both sides respectively, be provided with fixing hole and dashpot in the middle part of shell fragment, fixing hole is embedded on fixed leg, compresses rib and embeds in dashpot; If a base is fixed in lock panel, be provided with lock core hole in the middle part of base, both sides are all provided with fixing hole A and chute, and admittedly, chute presses on shell fragment two ends and produces certain precompression and pressed on by Lock cylinder cover in lock core cap bore for fixing hole A and base fixed leg spiral shell; If a block, be provided with curved guiding surface in the middle part of it, both sides are provided with fixing hole B and the block fixed leg spiral shell of lock panel internal lock core cap one end solid.When pressing Lock cylinder cover, Lock cylinder cover starts to slide backward under the guiding of curved guiding surface, simultaneously, locating piece exits avoiding hollow groove, Lock cylinder cover and shell fragment slide backward until limited block place along gib block and chute, realize fast open and to undo the lock core cap function, reach the object exposing lock core hole; When again press Lock cylinder cover move forward to contact with block time, rely on shell fragment active force by the locating piece of Lock cylinder cover press-in avoiding hollow groove in, realize Lock cylinder cover and automatically restore in lock core cap bore.
