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

Security door limit lock

Technical field

The utility model belongs to lock technology field, particularly a kind of limit lock that is used with door lock on the security door that is applicable to.

Background technology

For improving the theftproof performance of security door, people set up the limit lock on security door, the limit lock is locked fork with the world in the door lock connect, and drive the switch of limit lock with the switch of door lock.It is big that existing security door limit is being latched in volume, stirs dumbly, anti-pulls out, the weak point of pick-proof poor-performing.

Summary of the invention

It is big that the utility model is locked existing volume at existing security door limit, stirs dumbly, anti-pulls out, the weak point of pick-proof poor-performing, provides a kind of volume little, stirs flexibly, the security door limit lock that anti-ly pull out, the pick-proof performance is good.

The technical solution adopted in the utility model is finished in the following way: security door limit lock comprises panel, two dead bolt hooks, short strike plate, lock box, slide, lock box cover, long strike plate.Wherein, two dead bolt hooks are installed between short strike plate and the long strike plate, are provided with spring between two dead bolt hooks; Link together by pin hinge between dead bolt hook and short strike plate and the long strike plate; Be fixed together the formation dead bolt by steady pin between short strike plate and the long strike plate; Panel and lock box are fixed together; The slide socket at the two ends up and down of lock box is passed at two of slide respectively; The head of the dead bolt of the buckle of being made up of dead bolt hook, short strike plate and long strike plate is inserted in the dead bolt hole of panel, and the afterbody of the dead bolt of buckle is placed in the groove on the lock box inwall; Be provided with pin on the dead bolt of buckle, pin is inserted in the oblique chute and the straight runner on the lock box on the slide.During installation, the utility model is contained in respectively on the security door of upper and lower of security door door lock, pitches interlock together with the world lock of door lock by the dead man that slide in the lock of limit is provided with.The security door that the utility model security door limit lock is housed in use, use the key turns door lock core, move up and down by the world lock fork of door lock and the interlinked mechanism drive slide of dead man, and force in the oblique chute of pin on slide on the buckle dead bolt and slide, thereby it is flexible to drive the buckle dead bolt, drive the tongue hook simultaneously and open, withdraw, realize the switching of limit lock.

The utility model security door limit lock and the phase-locked ratio in existing security door limit, it is little, simple in structure to have a volume, stir flexibly, the characteristics that anti-pull out, the pick-proof performance are good have improved the theftproof performance of security door greatly, and the utility model is specially adapted to the limit lock that is used with door lock on the security door.
