Description
Technical field
The present invention relates to a kind of mechanical lock, specifically a kind of mechanical linkage lock.
Background technology
Existing mechanical lock is generally used for antitheft door of entering the room, and is mostly installed by developer is unified, the relatively low A of security performance
Level lock is usually main product, there is certain deficiency in terms of safety.Skilled unlocking theft is a kind of new theft
Mode, suspect, using the skilled unlocking instrument of specialty, can open the door lock of antitheft door, enter the room robber at short notice
Steal, and stolen after, the door lock of antitheft door still stands intact.With the improvement of people's living standard, interior door (is included not
Villa, the balcony door of private courtyard and courtyard door etc.) the requirement of safety also gradually step up.Interior door generally comprises active door
And passive door, active door is installed main lock, passive door is installed secondary lock, active door and passive is realized by the cooperation of major and minor lock
The folding of door.But the door latch structure of existing interior door is typically more simple, between active and passive door, often only pass through a piece of locking plate
Connect, safety and anti-theft are poor, and need the locking bolt manually pulling passive header and bottom that passive door is solid
It is scheduled on doorframe, secondary lock needs first to turn back locking bolt before unlocking, operation inconvenience.
Content of the invention
The technical problem to be solved is：There is provided a kind of safety and theftproof performance good mechanical linkage lock.
The present invention solves the technical scheme that adopted of above-mentioned technical problem：A kind of mechanical linkage lock, including being installed on master
The main lock of dynamic door and the secondary lock being installed on passive door, described main lock includes the first lock housing and is mounted on described first
Dead bolt in lock housing, locking bolt, locking bolt drive mechanism, the first upper connecting rod, first time pull bar and the first pull bar drive mechanism, described
Locking bolt drive mechanism is used for driving described locking bolt transversal stretching, and the first described pull bar drive mechanism is used for driving described the
One upper connecting rod and first time described pull bar longitudinal folding simultaneously；Described secondary lock includes the second lock housing and is mounted on institute
The second upper connecting rod in the second lock housing of stating, second time pull bar, the second pull bar drive mechanism and the second pull bar fixed mechanism, described
The second upper connecting rod be connected with upper latch, second time described pull bar is connected with lower latch, described the second upper connecting rod with described
Second time pull bar between be provided with cavity for accommodating described locking bolt, the second described pull bar drive mechanism is used for driving institute
The second upper connecting rod stated and second time described pull bar longitudinal folding simultaneously, the second described pull bar fixed mechanism is used for fixation and beats
The second upper connecting rod opened and second time pull bar；Described master locks and is provided with misoperation-proof mechanism, and described misoperation-proof mechanism is used
Lock in preventing door from not shutting completely, after locking, locking bolt stretches in cavity, the first upper connecting rod and first time pull bar be arranged on
Corresponding lock point on doorframe is connected, and upper latch and lower latch are connected and pass through to the corresponding lock point being arranged on doorframe
Second pull bar fixed mechanism is fixed, and finally realizes locking while master key and secondary lock.
After mechanical linkage lock of the present invention is installed, main lock is arranged on active door, and secondary lock is arranged on passive door.Machine of the present invention
Tool blocking lock is provided with misoperation-proof mechanism, can prevent door from not shutting completely and lock, and lifts the safety locked, and after locking, leads to
Cross locking bolt and the first upper connecting rod and first time pull bar carries out dual fixation to active door, by upper latch and lower latch to passive door
It is fixed, be connected by locking bolt between active door and passive door, safety and anti-theft that mechanical linkage of the present invention is locked
Can be good.
