Description

The metal anti-theft door of band interlock dead bolt

The utility model relates to building unit, particularly a kind of metal anti-theft door with the interlock dead bolt.

At present, though certain safe antitheft effect is arranged, also there is weak point in the security door that general family uses, and the intensity that is exactly door is low, is unable to undergo the collision of action of gravity, and is prized easily.The multi-faceted door lock of the use that has, but difficulty is installed, the moment of torsion of twisting key is bigger.And have in order to improve theftproof performance, establishing one anti-theft fence outdoors in addition.So not only increased extra expenses, and used also inconvenient to the user.

The purpose of this utility model provides a kind of simple in structure, and is easy to operate, has the high strength that constitutes with three Square lock bolts of door lock interlocking, a kind of security door that difficult quilt is prized.

The purpose of this utility model is achieved by the following scheme: this security door constitutes by doorframe, door leaf and door lock with the handle of locking interlock.Said door lock has the dead bolt of a plurality of mutual interlocks, and it is separately positioned on top, side and the below of door.Wherein upper lock tongue is connected the upper end of junction plate, this junction plate by steady pin be arranged on the door interlayer, the lower end of junction plate is hinged by connecting rod and crank.Be positioned at simultaneously on this crank and also have two tie points, one hinged by connecting rod and side dead bolt, and another is connected with an end of adjusting rod by connecting rod, and the other end of adjusting rod and rocking arm one end are hinged, and the other end of rocking arm is hinged by connecting rod and following Square lock bolt.The dead bolt fixed head of said door lock is provided with a driving lever, and the square hole of movable plate fuse is inserted in the termination of driving lever.

The utility model has simple in structurely, easy to operate compared with the prior art, installs easily.High-strength anti-theft structure with each Square lock bolt formation that opens and closes with door lock interlocking.Adopted outer dress theftproof lock and spherical handle linkage, door lock combines as a whole with the handle of the usefulness of opening the door, and makes handle both can reach the function that opens and closes lock, can make handle simultaneously again and use.The interlocking mechanism of dead bolt, crank, connecting rod are all hidden by safe-guard door lock and trim, and flat appearance is attractive in appearance.This security door only needs a key just each Square lock bolt can be opened simultaneously simultaneously, and it is not only convenient but also save trouble to operate.

Below in conjunction with accompanying drawing the utility model is illustrated.

15,16, side chain tongue 17, connecting rod card 18, adjusting Connecting rod 19, rocking arm 20, fixed axis 21, connecting rod 22, hinged pivot pin 23, Lower dead bolt 24, doorframe snap close stiffener 25, dead bolt guard shield 26, inner cover plate 27, Decorative panel 28, straight pin 29, square shaft protheca 30, square shaft 31, front chock plug 32, front hand grip ball 33, inner bearing plate 34, outer shaft board 35, screw 36, Overlap 40 behind rear chock plug 37, sleeve pipe 38, back handle ball 39, the square shaft, screw 41, cover plate 42, lock core fixed cover 43, three intraocular pressure plates 44, lock core 45, Fixedly key seat 46, pin 47, movable plate fuse 48, protective plate 49, dial Bar 50, split pin 51, spring 52, screw 53 consist of jointly.

Embodiment: front hand grip ball 33, square shaft protheca 30 are solidified as a whole with square shaft 31 usefulness straight pins 29, and square shaft 31 inserts in the square hole of crank 13, and cover 40 is solidified as a whole behind back handle ball 39 and the square shaft, and fastening by sleeve pipe 38 and square shaft with screw 36.Outer shaft board 35 is an one with the 34 usefulness closing-ups of inner bearing plate.The outer shaft board is fixed on the door leaf 1 with screw 41 in two pairs, supports front hand grip ball 33, back handle ball 39 and crank 13 respectively.The door leaf plate is recessed before and after when preventing that screw 41 from tightening, and is provided with U-shaped plate 14 in the door leaf plate of front and back.Inside and outside the door leaf plate is installed, be protruding with key in the circular hole of shaft bearing plate, insert in the keyway of inner bearing plate 34, to prevent inside and outside shaft bearing plate rotation.Inner cover plate 27 cooperates for being pressed into decorative panel 28, and its bossing is used for inserting the hole of outer shaft board 35.The decorative panel 28 that turns clockwise promptly is fixed on the door leaf 1.

Crank 13 is provided with three holes, and it is hinged with connecting

rod

12,15,16 respectively.Wherein connecting rod 12 is hinged with junction plate 10 lower ends, and junction plate 10 upper ends and upper lock tongue 4 usefulness bolts and pin are solidified as a whole.Connecting rod 16 is hinged with side chain tongue 17, and connecting rod 15 is solidified as a whole by bolt and connecting rod card 18 with adjusting rod 19.The other end of adjusting rod 19 and rocking arm 20 1 ends are hinged, and rocking arm 20 is that fulcrum swings with fixed axis 21, and the other end of this rocking arm and connecting rod 22 are hinged, and the other end of connecting rod 22 and following dead bolt 24 are hinged.When rotating front hand grip ball or back handle ball, upper lock tongue 4, side chain tongue 17, following dead bolt 24 all can stretch out retraction; Handle ball can be shaken hands simultaneously, and the pulling door leaf opens and closes.

Junction plate 10 is that fulcrum slides up and down with steady pin 11, and its slotted hole limits the stroke of three Square lock bolts.Also be provided with simultaneously a spring support 8 on junction plate 10, the slotted hole of the spring support steady pin 11 of packing into, the circular hole of its other end are packed on the steady pin 47 of junction plate 10.One end of spring 9 is arranged on the support 8, and the other end is contained on the steady pin 11, and spring support 8 is that fulcrum slides with steady pin 11.Thereby when junction plate 10 slided up and down, under the effect of spring 9, upper lock tongue 4 not reason deadweight glided.

Door lock 7 of the present utility model is common theftproof lock, and a driving lever 50 is set on its dead bolt fixed head, and driving lever 50 is inserted in the square hole of movable plate fuse 48.When the dead bolt move left and right of door lock 7, driving lever promptly drives movable plate fuse 48 and movable plate 5 move left and right.When upper lock tongue 4 extreme position up, during door lock 7 lockings, movable plate 5 moves to limit on the left, and its protruding jaw promptly blocks the upper lock tongue breach.Upper lock tongue 4, side chain tongue 17 and following dead bolt 24 are in blocking at this moment.Otherwise upper lock tongue 4,

side chain tongue

17 and 24 of following dead bolts are in unlocking condition.When upper lock tongue 4 below the limit, during door lock 7 lockings, movable plate 5 moves to left and is obstructed, 50 of driving levers drive movable plate fuse 48 and move to left.At this moment, only need rotation front hand grip ball or back handle ball just upper lock tongue can be extended limes superiors.Movable plate 5 moves to the limit in the effect bottom left of spring 52, blocks the breach of upper lock tongue 4, and makes three Square lock bolt self-lockings.Therefore, no matter upper lock tongue does not all influence the door lock locking last or down during any position.

For improving the pick-proof and the anti-drilling performance of door, be equipped with bonnet lock hole stiffener 25 at the bonnet lock hole place of doorframe 2.Be provided with protected apron 49 in the front of movable plate 5.The jaw of lock core fixed cover 43 two ends projectioies inserts respectively in the stiffener and three intraocular pressure plates 44 of door leaf, rotates to prevent lock core 45, guarantees theftproof performance.
