Abstract

The utility model relates to a double-side anti-prizing door. Because the inner part of a door body adopts a linkage structure, namely that the outer parts of an upper and a lower push rods of an outer and an inner locks are sheathed with four hollow sleeve shafts, the other end of each hollow sleeve shaft is connected with a post rod and a convex wedge is arranged on the post rod. Therefore, a lock tongue can be respectively controlled to stretch out and reset by the way that the inner and the outer locks are locked and unlocked, namely when the outer lock is locked, the inner lock can not drive the lock tongue because of the hollow sleeve shafts; on the contrary, after the inner lock is locked, the outer lock can not drive the lock tongue. Thereby, the double-side anti-prizing door has multiple locking points, and the anti-prizing purpose in double inner and outer sides is realized.

Description

A kind of two-sided anti-forcing open the door

The utility model belongs to use and locates fixed opening and closing device in the building access, promptly a kind of inside and outside two-sided anti-forcing open the door with a plurality of locking points.

At present people's anti-forcing open the door of generally using adopts inside and outside double-level-metal thin plate to make, and its inside has a bolt-type locks a little up and down, but the lock point less, the position deviation is big, promptly allows to locking, still has the deficiency of being pried open in the short time.

In view of the deficiency that prior art exists, the purpose of this utility model is a kind of novel two-sided anti-forcing open the door of locking the equal energy of a little many, inside and outside lockings pick-proof of design.

Principal character of the present utility model is to adopt linkage structure, promptly in the door body up and down the outside of each two tappet be with four empty sleeves, be linked together with empty sleeve link rod between the empty sleeve, the other end of empty sleeve and upper and lower push rod join; Respectively be provided with a protruding wedge in the upper and lower push rod.When outer lock key was done the locking rotation, external lock driver blade drivening rod, tappet, empty sleeve stretched out push rod and protruding wedge.When protruding wedge stretches out, make the roller drive link that connects the side dead bolt stressed, thereby body dead bolt upper and lower and side is stretched out simultaneously, finish the lock out action of Men Tisan face.At this moment, in drawn back the gap between the empty sleeve locked and tappet, so the internal lock driver blade can not drive dead bolt.Because reset tension spring up and down is housed between upper and lower two empty sleeve link rods, and the other end of roller drive link is equipped with the side direction reset tension spring.When outer lock key was done the unlatching rotation, reset tension spring played the involution effect, dead bolt involution simultaneously original position.

Interior lock key is done locking and is opened when rotating, and its operating principle is the same.When the internal lock driver blade was done the locking rotation, drawn back gap between outer empty sleeve of locking and tappet this moment, so the external lock driver blade can not drive dead bolt.

It is many to the utlity model has around the body locking point, is distributed symmetrically, simple and reasonable characteristics, has reached not only outer locking pick-proof but also the interior locking purpose of pick-proof too.

Accompanying drawing 1 is the utility model sectional structure schematic diagram.

Accompanying drawing 2 is the utility model elevations.

As shown in drawings: door body 1 adopts double-layer plate to make, in door body 1 above, can establish supervising device 2, peephole 3; Middle part set up defences sled, the anti-drilling external lock 5 of door body 1; One side of door body 1 is provided with common latch and dead bolt 4, and opposite side is provided with the hinge that bears the load effect 23 that is connected with doorframe, and can set a pinning 24.Internal construction of the present utility model is upper and lower symmetrical expression.Hollow position in door body 1 has external lock driver blade 6 that links to each other with external lock 5 and the internal lock driver blade 7 that links to each other with internal lock.The internal lock connecting rod 9 that external lock connecting rod 8 that external lock driver blade 6 connects and internal lock driver blade 7 connect is connecting outer locking tappet 10 and interior locking tappet 11 again respectively.The outside of upper and lower each two tappet 10,11 is with four empty sleeves 12,13, between tappet and the empty sleeve slidably.Be bound up with empty sleeve link rod 17 between the empty sleeve 12,13, empty sleeve link rod 17 middle parts are provided with reset tension spring 15 up and down, and the other end and the push rod 14 of empty sleeve 12,13 join.Respectively be provided with a protruding wedge 16 in the upper and lower push rod 14, the wedge portion of protruding wedge 16 is tight against roller drive link 18, and an end of roller drive link 18 is connected with side direction reset tension spring 19, and the other end links to each other with side dead bolt 22.Doing locking when external lock 5 key turns rotates, external lock driver blade 6 drives external lock connecting rod 8, outer locking tappet 10, empty sleeve 12,13 and push rod 14, when push rod 14 stretches out, protruding wedge 16 moves simultaneously, masterpiece is used for roller drive link 18, the pulling force that makes side dead bolt 22 overcome side direction reset tension spring 19 stretches out, and inserts in the doorframe locked groove, finishes the side lock out action of a body 1.On the top of upper and lower push rod 14, can connect with upper and lower dead bolt 20,21 via upper and lower dead bolt link rod, upper and lower dead bolt can be respectively two or one; When external lock 5 keys were done locking and rotated, push rod 14 drove upper and lower dead bolt 20,21 and stretches out, and inserted in the doorframe locked groove, thereby had increased the locking point of door body 1, promptly finished lock out action simultaneously at three faces of door body 1.In the foregoing description, also can remove protruding wedge 16, roller drive link 18, side dead bolt 22 and side direction reset tension spring 19 in the push rod 14,, finish the lock out action of upper and lower two faces of a body 1 at last promptly by the twist-lock of external lock 5 keys.When external lock 5 key turns lock, drawn back the gap between interior locking tappet 11 and the empty sleeve 13, so can not driving dead bolt, opens internal lock driver blade 7.When the key of external lock 5 was done breakdown action, push rod 14 was because the involution tension of reset tension spring 15 and side direction reset tension spring 19 up and down, the dead bolt of each face involution simultaneously original position.

When the internal lock key turns is done the locking rotation, internal lock driver blade 7 drives internal lock connecting rod 9, interior locking tappet 11, empty sleeve 12,13 and push rod 14, its operating principle locks with external lock, and drawn back gap between outer locking tappet 10 and the empty sleeve 12 this moment, opens so external lock driver blade 6 can not drive dead bolt.
