Abstract
The utility model discloses an interlocking device for pick-proof doors, comprising a main lock body (6) fixed on a door leaf (2), upper and lower lock levers (5,7), upper and lower lock points (1,10), as well as upper and lower side locks (3,9). The door leaf (2) on the hinge side is provided with horizontally arranged upper and lower lock points (12, 14) on which horizontal lock levers (11,13) are serially arranged; the upper and lower horizontal lock levers (11, 13) are serially hinged with one ends of the upper and lower poking forks (4,8) arranged on the door leaf (2), while the other ends of the upper and lower poking forks (4,8) are respectively connected with the upper and lower lock levers (5,7). Through such a structure, the pick-proof door leaf (2) can be interlocked around; the utility model has the advantages of simple structure, easy operation, interlocking and linkage of lock points, and better pick-proof performance.
Description
One, technical field
The invention relates to a kind of anti-theft device of security door, has the antitheft interlock of Anti-picking lock around particularly a kind of security door.
Two, background technology
Development and growth in the living standard along with society, office and the safe precaution measure of inhabitation place also require more and more higher, the quality of the theftproof performance of entering house door directly has influence on the safety of the property and the person, and for this reason, the entering house door great majority have all used the Multiple locking point security door.But the security door that uses all can only be locked by theftproof lock and by theftproof lock drive limit lock and upper and lower lock point at present, the security door hinge side then can't be locked to door frame from door leaf by theftproof lock, security door can not from around lock, in case prized, just do not have antitheft effect.
Three, summary of the invention
In order to overcome the disadvantage of above-mentioned existence, the invention provides a kind of simple in structure, a lock point interlocking linkage, the better security door interlock of pick-proof performance.The invention solve technical scheme that its technical problem adopts comprise the main lock body that is fixed on the door leaf, the locking bar up and down that is connected with main lock body, successively be fixed on the locking bar up and down lock point up and down and be fixed on the door leaf and is connected with locking bar up and down successively go up following the lock, the door leaf top of described hinge side is provided with the horizontally disposed cross locking point of going up, be fixed with the cross locking bar on the last cross locking point, last cross locking bar is hinged with the upper shift fork that is arranged on the door leaf, and the upper shift fork other end is connected with last locking bar.
The door leaf bottom of described hinge side is provided with horizontally disposed cross locking point down, is fixed with down the cross locking bar on the following cross locking point, and following cross locking bar is hinged with the lower shift fork that is arranged on the door leaf, and the lower shift fork other end is connected with following locking bar.
After adopting said structure, when security door is locked, when theftproof lock drives upper and lower lock point and upper and lower limit and locks lock by upper and lower locking bar, upper and lower locking bar drives the upper and lower cross locking point that is fixed on the upper and lower cross locking bar by upper and lower shift fork and locks, and makes the antitheft door leaf upper and lower, left and right can both be linkage interlocked; Have advantages such as simple in structure, easy to use, a lock point interlocking linkage, pick-proof performance be better.
Four, description of drawings
Fig. 1 is the structural representation of the invention.
Five, the specific embodiment
Shown in Figure 1, specific embodiments for a kind of security door interlock of the invention, it comprises the main lock body 6 that is fixed on the door leaf 2, the locking bar up and down 5 that is connected with main lock body 6,7, be fixed on locking bar 5 up and down successively, lock point up and down 1 on 7,10, and be fixed on the door leaf 2 and successively with locking bar 5 up and down, 7 bottoms of going up that connect lock 3,9, the door leaf 2 of described hinge side be provided with horizontally disposed on, following cross locking point 12,14, on, following cross locking point 12, be fixed with successively on 14, following cross locking bar 11,13, on, following cross locking bar 11,13 successively be arranged on the door leaf 2 on, lower shift fork 4,8 is hinged, on, lower shift fork 4,8 other ends are respectively with last, following locking bar 5,7 connect.
Its course of work is as follows, when locking, theftproof lock 6 drives upper and lower lock point 1,10 by upper and lower locking bar 5,7 and upper and lower limit lock 3,9 is locked, simultaneously, upper and lower locking bar 5,7 drives the upper and lower cross locking point 12,14 that is fixed on the upper and lower cross locking bar 11,13 by upper and lower shift fork 4,8 and locks, and makes the antitheft door leaf 2 can both be linkage interlocked all around.When unblanking, its operating principle is opposite when locking, and no longer repeats at this.
Claims (2)
1, a kind of security door interlock, comprise the main lock body (6) that is fixed on the door leaf (2), the locking bar up and down (5 that is connected with main lock body (6), 7), be fixed on locking bar (5 up and down successively, 7) point of lock up and down (1 on, 10), and be fixed on that door leaf (2) is gone up and successively with locking bar (5 up and down, 7) bottom of going up that connects locks (3,9), it is characterized in that: the door leaf of described hinge side (2) top is provided with the horizontally disposed cross locking point (12) of going up, be fixed with cross locking bar (11) on the last cross locking point (12), last cross locking bar (11) is hinged with the upper shift fork (4) that is arranged on the door leaf (2), and upper shift fork (4) other end is connected with last locking bar (5).
