Abstract
The utility model discloses an anti-theft door thick door leaves interlocking device, comprising a main locking body (3), an upper and a lower connecting rods (6 and 9), an upper and a lower locking heads (8 and 13), an upper and a lower cross locking points (7 and 12). An upper and a lower locking points (5 and 10) are fixed on a frame of the door leaf (2) which has different sectional planes with the main locking body (3); an upper lateral rod (4) is connected between the upper locking point (5) and the upper connecting rod (6); a lower lateral rod (11) is connected between the lower locking point (10) and the lower connecting rod (9). After adopting the structure, the main locking body (3) drives the upper and the lower locking heads (8 and 13), the upper and the lower cross locking points (7 and 12) to lock, via the upper and the lower connecting rods (6 and 9). Simultaneously, the upper and the lower connecting rods (6 and 9) drive the upper and the lower locking points (5 and 10) to lock, via the upper and the lower lateral rods (4 and 11), so that different sectional planes are provided with a plurality of locking points matched with locking holes of a doorframe (1). The utility model has the advantages of simple structure, better antiprizing performance, etc.
Description
Technical field
The utility model relates to a kind of fixture of security door, the interlock of the thick door leaf of particularly a kind of security door.
Background technology
Along with the development and the growth in the living standard of society, office and the safe precaution measure of inhabitation place require more and more higher, and 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 provided with the lock point at grade at present, and the pick-proof poor performance does not have real antitheft effect.
Summary of the invention
In order to overcome the disadvantage of above-mentioned existence, the utility model provides a kind of simple in structure, lock point not on same plane and the better thick door leaf interlock of security door of pick-proof performance.The technical scheme that its technical problem that solves the utility model adopts comprises main lock body, upper and lower strut, go up lower lock head and cross locking point up and down, main lock body is fixed on the door leaf, upper and lower strut is symmetricly set on the main lock body, last lower lock head is separately fixed at the end of upper and lower strut, the cross locking point is fixed on the frame of door leaf and is connected with upper and lower strut successively up and down, with the door leaf frame of the different sections of main lock body on be fixed with and lock up and down a little, locking a little and between the last connecting rod is connected with cross tube, is connected with sheer pole between following lock point and the lower link.
After adopting said structure, when main lock body is locked, main lock by upper and lower strut drive go up lower lock head and up and down the cross locking point lock, simultaneously, upper and lower strut drives up and down the lock point by last sheer pole again and locks, and making on the different sections of door leaf has the lockhole of a plurality of lock dotted or gate frames to cooperate; Have advantages such as simple in structure, that the pick-proof performance is better.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the A-A sectional view of Fig. 1.
The specific embodiment
Illustrated in figures 1 and 2, specific embodiments for the thick door leaf interlock of a kind of security door of the utility model, it comprises main lock body 3, upper and lower strut 6,9, last lower lock head 8,13 and cross locking point 7 up and down, 12, main lock body 3 is fixed on the door leaf 2, door leaf 2 is hinged on the doorframe 1, upper and lower strut 6,9 are symmetricly set on the main lock body 3, last lower lock head 8,13 are separately fixed at upper and lower strut 6,9 end, cross locking point 7 up and down, 12 are fixed on the frame of door leaf 2 and by rocking arm and upper and lower strut 6 on it, 9 connect, with door leaf 2 frames of main lock body 3 different sections on be fixed with lock point 5 up and down, 10, locking a little is connected with cross tube 4 between 5 rocking arm and the last connecting rod 6, is connected with sheer pole 11 between the rocking arm of following lock point 10 and the lower link 9.When main lock body 3 is locked, main lock by upper and lower strut 6,9 drive go up lower lock head 8,13 and up and down cross locking point 7,12 lock, simultaneously, upper and lower strut 6,9 is locked point 5,10 up and down by last sheer pole 4,11 drives again and is locked, the lockhole that a plurality of lock dotted or gate frames 1 are arranged on the different sections of door leaf 2 is cooperated, thereby reach the better purpose of pick-proof performance.
