Abstract
The utility model relates to an anti-theft door lock coupled device. The utility model is characterized in that a coupled rod installed in an anti-theft door is connected with a rack bar which is engaged with a rotating gear which is connected with a rotating handle, and the coupled rod is connected with a door bolt. When the anti-theft door lock coupled device is used, a puzzle lock is pulled, a key is inserted in a lock core, the rotating handle is rotated to drive a pull fork to touch a gear pulling pin, and the rotating gear is rotated, so the door bolt is inserted or pulled out of a door bolt hole through the rack bar and the coupled rod, and the anti-theft door lock coupled device achieves the goal that the door is opened and closed. The utility model has simple structure, convenient use and high safety and can optionally lock the door from an inner and an outer sides.
Description
The utility model is a kind of safe-guard door lock linkage, belongs to the technical field of door.
Security door of the prior art is of a great variety, some security doors utilize the interlock rod member to connect door bolt and turning handle, when handle rotates, drive the motion of interlock rod member, make door bolt that door is stuck in, thereby reach the purpose of safe antitheft, the problem that its exists is: the inside and outside both sides at door can not live door lock arbitrarily, antitheft, and the structure of rotary door latching segment is too simple and safety factor is little.
The purpose of this utility model is to invent a kind of anti-theft device that can arbitrarily door be pinned from medial and lateral, lock and coded lock are arranged on its external handle, returning device is installed in door, is made the interlinked mechanism freely-movable, like this door inside and outside can both be freely door lock is good antitheft.
The utility model is to constitute like this: utilize the trace (18) that is installed in the security door (12) to connect tooth bar (17), tooth bar (17) and transmitting gear (8) engagement, transmitting gear (8) connects with turning handle (1) again, trace (18) connects keeper (20), install and fix cover (6) in the outside of door (12), fixed cover (6) overcoat coded lock (7), turning handle (1) utilizes connector (16) to connect with fixed cover (6), lock core (2) is installed in the turning handle (1), lock core (2) passes the center of transmitting gear (8), be fixed on the inside door handle (10) by pin (11), the same side is mounted with gear finger (24) on transmitting gear (8), spring returning device (13), shift fork (9) is fixed on the turning handle (1), shift fork (25) is fixed in the door (12), and tooth bar (17) is fixed on the door (12).
Compared with prior art, the utility model is simple in structure, esy to use, safe and reliable, can arbitrarily door be pinned from medial and lateral.
Accompanying drawing 1 be structural representation of the present utility model, accompanying drawing 2 be scheme of installation,
Accompanying drawing 3, accompanying drawing 4 are other block diagram.
Embodiment of the present utility model: utilize to be installed in inner trace (18) the connection tooth bar (17) of security door (12), tooth bar (17) and transmitting gear (8) engagement, transmitting gear (8) connects with turning handle (1) again, trace (18) connects keeper (20), install and fix cover (6) in the outside of door (12), fixed cover (6) overcoat coded lock (7), turning handle (1) utilizes bolt (16) to connect with fixed cover (6), lock core (2) is installed in the turning handle (1), lock core (2) passes the center of transmitting gear (8), be fixed on the inside door handle (10) by pin (11), the same side is mounted with gear finger (24) on transmitting gear (8), spring returning device (13), shift fork (9) is fixed on the turning handle (1), shift fork (25) is fixed in the door (12), and tooth bar (17) is fixed on the door (12).
When opening the door outdoors, Coded lock (7), key (5) is inserted in the lock core (2), rotation turning handle (1), drive shift fork (9) bump gear finger (24), make transmitting gear (8) rotate, by tooth bar (17), trace (18), make keeper (20) leave the keeper hole like this; When outdoors at closing time, rotate turning handle (1) and drive transmitting gear (8) rotation, like this by tooth bar (17), trace (18), make keeper (20) insert the keeper hole; At Men Neikai at closing time, rotary door inner handle (10) makes turning handle (8) rotate, thereby reaches the purpose of locking a door, opening the door.
