Description
Technical field
The utility model relates to lock class field, especially automobile door lock.
Technical background
In different places, various objectives needs different locksets, and as in the hotel, the passenger constantly changes, and just requires door lock to have the function of changing unlocking cipher at any time; In order not allow others use vehicle, just require lock to have the function of the wheel of preventing; In order to start motor, just need lockset that the function of connecting circuit is arranged.Up to the present lockset has had considerable kind.We disclose a kind of automobile door lock in application number is 02237797.2 patent application document, it is to be connected the gear-driven three-dimensional lock that designs at door leaf by hinge with doorframe, but it is the External tilting doors that occupy little space that many doors are arranged on automobile, the compartment is to be connected with axle by rocking arm with door leaf, car door is whole outwards when opening, to the next door translation, expose door, four limits of door leaf all break away from doorframe, when closing door leaf when locking, the lockset that four limits and the doorframe of door leaf all need be fixed just, so for this new application target, must the new lockset of design.
Summary of the invention
The purpose of this utility model provides a kind of simple in structure, safe and reliable, the four-way lock that need pin the four direction person of door leaf.
The technical solution of the utility model is as follows: the four-way lockset has lock housing, locking bolt, gear drive assembly, locking bolt detent mechanism, locking bolt locking mechanism, on off state indication mechanism.Upper and lower, left and right four direction on plane, gear drive assembly place all is equipped with locking bolt, and locating slot and locked groove are separately positioned on two locking bolts.On locked bolt, have locked of locked of key and electromagnetism simultaneously.
One end of each locking bolt is a tooth bar, and with driven wheel engagement, the other end of locking bolt stretches out lock housing, cooperates with set bar groove on the doorframe, has sliding tray on locking bolt.
Near locked groove relevant position has locked bolt, in locked bolt, has tightening latch, has locked of the key that locked jack of key and eccentric lock pull bar form on the locked bolt, the eccentric lock pull bar connects tightening latch, the tightening latch afterbody stretches out from the other end of locked bolt, is the attraction head of locked of electromagnetism, is the electromagnetic draw bar assembly in the outside that attracts head, it is made up of electromagnet and pull bar, and pull bar is connected by mechanical fixed part with attracting head.
At the position corresponding, lock housing bottom with sliding tray, be fixed with the fixed high axle of locking bolt, the fixed high axle of locking bolt has axis body, the shaft shoulder and spindle nose, and the shaft shoulder is held locking bolt, and spindle nose passes from sliding tray, fixes with locking bolt.
The utility model has been realized from four direction the dead purpose of door lock is difficult for prying open, and security reliability height, locked bolt have possessed the locked and locked function of electromagnetism of key simultaneously, have the characteristics of compact conformation, also have characteristics simple in structure, easy to use.
