Abstract
The utility model belongs to the technical field of locksets, particularly an edge lock which is applicable to match with a door lock to use on a burglarproof door. The utility model aims at solving tThe utility model belongs to the lock technology field, in particular to a chain applied in a security door to be coordinately used with. The utility model is designed to overcome the deficiencies of he disadvantages of large volume, inflexible toggling and poor toggle prevention and prize prevention performance of the existing edge lock for the burglarproof door to provide the edge lock which hasthe prior security door chain on large volume, inflexible poke, as well as relatively weak pick-up resistant and tamper-resistant performance, so as to provide a security door chain with small volume, the advantages of small volume, flexible toggling and favorable toggle prevention and prize prevention performance. The edge lock for the burglarproof door comprises a panel, two latch bolt hooks, a flexible poke, as well as good pick-up resistant and tamper-resistant performance. The security door chain comprises a faceplate, two bolt hooks, a short bolt piece, a lock box, a slide, as well as ashort latch bolt sheet, a lock box, a sliding sheet, a cover for the lock box and a long latch bolt sheet. The utility model is characterized in that the two latch bolt hooks are installed between the long bolt piece. The essentials are: the two bolt hooks are arranged between the short bolt piece and the long bolt piece, and a spring is arranged between the two bolt hooks; the bolt hooks are hing short latch bolt sheet and the long latch bolt sheet, springs are arranged between the two latch bolt sheets, the latch bolt hooks are connected with the short and the long latch bolt sheets by hingeed with the short bolt piece and the long bolt piece; the short bolt piece and the long bolt piece are fixedly connected to form a bolt. In use, the key rotates the door lock plug, so as to propel thes, and the short and the long latch bolt sheets are fixedly connected together to form a latch bolt. When the utility model is used, a key is rotated in a lock core of the door lock, and the latch bol bolt expand and contract through a linkage mechanism of a multi-lock system fork and button rod of the door lock, and simultaneously propel the bolt hooks open and retract, thereby realizing the chait is driven by a lock fork of the door lock and a shift rod to expand or retract; at the same time, the latch bolt hooks are driven to spread and retract, and thus, the edge lock can be unlocked or lon switching. cked.
Description
