Abstract
The utility model relates to a safety door lock with multiple tamper-resistance and anti-theft function, which comprises a mechanical lock arranged on a safety door. A sliding plate (5) arranged on the mechanical lock is connected with the latch (2) which is retractable and arranged on a bracket (11) of the inner wall of the safety door (1); the sliding plate (5) can move in tandem with the rotating of an open spanner arranged on the safety door (1). The safety door lock is characterized in that a rotating component (21), which can rotate and can coincide with the latch (2), is arranged in the middle of the latch (2); and the transverse distance (b) of the rotating component (21) is longer than the vertical distance (a) of the rotating component (21); and the rotating component (21) can move in tandem with an unlocking lock arranged on the safety door (1) through a transmission mechanism. Compared with the prior art, the safety door lock provided by the utility model has the advantages that after the latch stretches out and locks the door, through rotating the unlocking lock, the rotating component can be driven to rotate; since the transverse distance of the rotating is longer than the vertical distance, the transverse convex part after the rotating forms a reverse blocking component of the latch; because the reverse block component is reversely blocked on a door frame, the tamper resistance of the safety door lock can be effectively reinforced, therefore, the safety door achieves better and stronger anti-theft function.
Description
Technical field
The utility model relates to a kind of door latch structure that uses on strongbox, safety cabinet or the national treasury door of valuables, particularly a kind of insurance lock with multiple pick-proof and anti-theft function deposited.
Background technology
The existing lockset that is used for strongbox, safety cabinet or national treasury door, generally be divided into mechanical lock and electronic lock two big classes, and adopt mechanical lock and electronic lock simultaneously is a kind of more satisfactory combination, can be spacing by the executing agency of mechanical lock, electronic lock respectively by the latch board that rotatable handles control is moved; Usually, wherein the execution unit of electronic lock is an electromagnet and reducible armature thereof, under the electromagnet power failure state, its armature or insert or embed latch board in the groove that corresponding site is provided with the lock pin of this armature interlock, make this latch board spacing, have only after confirmation such as the password of electronic lock or fingerprint, the electromagnet energising, its armature is inhaled, thereby remove locking to latch board, at this moment, can drive with key operated mechanical lock and to contract in the latch board and unblank, be design scheme " a kind of combined mechanoelectric lock " (notification number is CN2525181Y) of the utility model patent " mechano-electronic dual fail-safe coded lock " of ZL87210847.3 and utility model patent ZL02215701.8 all provides as the patent No..But this machine insurance is locked in does not have back-off after bolt is locked, and is pried open easily, thereby makes safety lock ineffective, and its anti-theft effect is strong not enough, opportunity is arranged for robber person, so its structure awaits to improve.
The utility model content
Technical problem to be solved in the utility model is to provide a kind of design concept ingenious, rational in infrastructure and can form the insurance lock with multiple pick-proof and anti-theft function of back-off at the back bolt of locking at above-mentioned prior art present situation, with the anti-theft feature of reinforced safety door lock effectively.
The utility model solves the problems of the technologies described above the technical scheme that is adopted: this has the insurance lock of multiple pick-proof and anti-theft function, include the mechanical lock that is arranged on the security door, slide plate on the mechanical lock is connected with bolt, and the bolt telescopically is arranged on the support of security door inwall, and slide plate links with the rotation that is positioned at the unlatching spanner on the security door, it is characterized in that: its middle part of described bolt is provided with the rotatable rotating part that also can coincide with one with bolt, the lateral separation of this rotating part is longer than fore-and-aft distance, and rotating part links together by drive mechanism and the unlatching lock that is arranged on the security door.
As improvement, described rotating part is locked interlock concrete structure together by drive mechanism and the unlatching on being arranged at security door and is chosen as: its afterbody of rotating part is fixedlyed connected with rotor plate one end by outrigger shaft, and the other end of rotor plate is connected with motion bar movably, and described motion bar is connected with connecting rod one end, and the other end of connecting rod is connected with draw bar one end movably, and the other end of draw bar movably with stir piece one end and be connected, and the other end of stirring piece is connected with the unlatching on being arranged at security door is phase-locked by rotating shaft.
As further improvement, described bolt is preferably four, with each one of the flexible bolt of symmetry up and down, about flexible be two, two flexible about this bolts are arranged on the security door with upper-lower position, and described rotating part is in two flexible about being arranged at respectively bolts, rotating part by its extension be arranged at the motion bar two ends on each self-corresponding rotor plate be connected, and described connecting rod is fixedlyed connected with the middle part of motion bar.
Improve again, its inwall of described security door is provided with the device that automatically locks, about this device that automatically locks is positioned on the another side medium position of flexible bolt, include push rod, one end of this push rod extends outside insurance every limit, its other end contacts mutually with swivel plate, this rotation sleeve-board string is in rotating shaft, and rotating shaft is provided with the torsion spring that can automatically reply after swivel plate is rotated, end at swivel plate is provided with hook portion, under the state, hook portion and slide plate hook are put together on the described swivel plate after security door is opened, and slide plate links together with the torsion spring that can make slide plate stretch out bolt automatically.
Improve, the structure that hook portion and slide plate hook are put together on the described swivel plate is again: the hook portion of swivel plate and be fixed on the slide plate and put together with the suitable fixed block hook of swivel plate; The other end of described draw bar movably with stir the structure that piece one end is connected and be: draw bar by turning cylinder with stir piece and be connected.
Compared with prior art, the utility model adopts at the bolt middle part the rotatable rotating part that also can coincide with one with bolt is set, the lateral separation of this rotating part is longer than fore-and-aft distance, and rotating part links together by drive mechanism and the unlatching lock that is arranged on the security door.She Ji structure like this, stretch out and after locking at bolt, by rotating to open to lock rotating part is rotated, because the lateral separation of rotating is than vertically big, so postrotational horizontal protuberance just forms the back-off portion of bolt, because back-off portion is stuck on the doorframe, thereby increased the pick-proof structure one more, and back-off and doorframe buckle space are little, during pick-proof, stress that prizes and syndeton influence are less, and stress easily concentrates on the metal material, thereby strengthened the pick-proof performance effectively, made the anti-theft feature of security door better and stronger; When the utlity model has said structure in addition, electronic lock is installed simultaneously also on insurance lock, thereby has further strengthened the anti-theft effect of security door.Door lock of the present utility model also can be widely used in electronic lock strongbox or safety cabinet, mechanical lock strongbox or safety cabinet, national treasury door, Fingerprint Lock strongbox or safety cabinet and rifle cabinet etc.
