Abstract
The utility model discloses a theft-proof door edge lock. The utility model comprises a panel (1), a lock shell (6), a lock tongue (3), a trailing bar (2) and a push board (5), wherein the push board (5) is arranged between the trailing bar (2) and the bottom surface of the lock shell (6). An upper and a lower guide rods (7) on the push board (5) are orderly arranged in an upper and a lower push board jacks of the lock shell (5). The push board (5) is provided with an inclined slide slot (11). The push board (5) is provided with a push rod (13) which is connected with the push board (5) as integration and extends out of the lock shell (6) through a push rod hole of the lock shell. The bottom surface of the lock shell (6) is provided with a horizontal slide slot (10). The trailing bar (2) is fixedly provided with a trailing bar guide post (4) which is arranged in the inclined slide slot (11) and in the horizontal slide slot (10). Due to the adoption of the structure, the push rod (13) is driven by a theft-proof door lock, pushes the push board (5) to move up and down, and drives the trailing bar (2) sliding along the horizontal slide slot (10). Therefore, the utility model realizes locking and unlocking the edge lock, and solves the problems of complex edge lock structure, large size, no flexible poking and laborious unlocking.
Description
Technical field
The utility model relates to a kind of annex of safe-guard door lock, particularly a kind of limit lock that is used with safe-guard door lock.
Background technology
In order to improve the theftproof performance of security door, people also set up a plurality of antitheft limits lock at the periphery of security door except the structure of improving doorframe and door leaf, link together by link gear between limit lock and the door lock, during use, the limit is locked under the door lock drive and door lock is opened synchronously or closure.And existing security door limit be latched in complex structure, volume big, stir weak point such as dumb, the effort of unblanking.
Summary of the invention
For overcoming the disadvantage of above-mentioned existence, problem to be solved in the utility model provides a kind of security door limit rational in infrastructure, that feel light, stir flexible, volume is little, cost is low and locks.The technical scheme that its technical problem that solves the utility model adopts comprises panel, lock housing, dead bolt, planker, slurcam, panel is fixed on the lock housing, dead bolt is located in the dead bolt hole of panel, the afterbody and the planker of dead bolt are fixed, described slurcam is placed between the bottom surface of planker and lock housing, upper and lower guide peg on the slurcam is located in the upper and lower slurcam jack of lock housing successively, and slurcam is provided with oblique chute, and slurcam is provided with the push rod that is connected as a single entity and passes the lock housing push-rod hole and stretch out lock housing; The bottom surface of lock housing is provided with horizontal concrete chute, is fixed with the planker guide pillar on the planker, and the planker guide pillar is located in oblique chute and the horizontal concrete chute.
Flexible, light for the limit lock is opened, described lock housing is provided with the extension spring steady pin, is provided with extension spring between extension spring steady pin and push rod.State and be fixed with the upper and lower horizontally-guided bar that stretches out lock housing planker hole on the planker.
After adopting said structure, the push rod of limit lock fuses by link gear and safe-guard door lock, when using, safe-guard door lock drives push rod by link gear and slurcam moves up and down, being located at planker guide pillar in the oblique chute of slurcam drags planker and slides along horizontal concrete chute under the drive of slurcam, thereby it is flexible to drive limit lock dead bolt level, realizes that the limit lock opens and closes; Have advantages such as rational in infrastructure, that unlatching is light flexibly, feel is light, volume is little, the life-span is long.
