Abstract
The utility model discloses an anti-theft door, belonging to an anti-theft safety device for the houses of the architectural field. The anti-theft door is composed of a door leaf, a door frame, a door lock, and a rotating disk which is installed inside the door leaf and is connected with a handle and a bolt, a connecting rod, a crank, etc. A stop extending out of a lock box is welded on the bottom part of the inside of the set bar of the door lock, and the connecting rod is provided with a connecting rod stop on the position corresponding to the stop. When the anti-theft door is locked, the stop moves following the set bar, the stop blocks the connecting rod stop, the connecting rod can not move, and the bolt is locked thereby. The utility model has the advantages of easy installation, easy maintenance, and small force moment when the bolt is opened and closed; meanwhile, the bolt (locking point) is arranged inside the door leaf; moreover, the utility model has strong anti-theft ability, and the anti-damage ability is strong.
Description
The utility model relates to a kind of security door, belongs to the employed a kind of anti-theft safety device in building field house.
Existing security door is varied, the security door that the lockset that uses three orientation lock fixed points is arranged, but the lockset of these security doors all is a Built-in lock, be that lockset is installed in the door leaf the inside, lock core, key eye are only exposed in the outside, use the security door of this lockset to have following defective: installation difficulty is big, be difficult to maintenance, reliability is not high, and the moment of torsion of twisting key is bigger when opening and closing lockset, and women and children's inconvenience is used.
The purpose of this utility model be to provide a kind of easy for installation, maintenance easily, reliability is high and open and close the light and handy security door of lockset to overcome above-mentioned deficiency.
The security door that the utility model proposes is by door leaf, doorframe, door lock and be installed on the inner rotating disk that connects handle and latch of door leaf, connecting rod, crank etc. and form.Door lock adopts the fitted outside door lock, and the outer block of lock box is stretched out in one of the dead bolt of door lock inner bottom welding, and when opening and closing door lock, this block can be done horizontal linear with dead bolt and move.Be connected by a connecting rod between rotating disk and the crank, connecting rod one end is connected by the rotating shaft that is fixed on the disk edge axial direction, and the other end of connecting rod is connected on the pivot pin of crank end; Crank middle part is provided with a rotating shaft, and latch one end is connected with the other end pivot pin of crank, with the connecting rod of above-mentioned block relevant position on a connecting rod block is housed, handle is fixed on rotating disk central authorities.The twisting handle makes dial rotation, and radially rotating by the rotating shaft on the rotating disk of rotating disk moves up and down connecting rod, and moving up and down of connecting rod makes latch stretch out door leaf by crank, inserts doorframe, or the withdrawal door leaf.
Because the security door that the utility model proposes adopts outer dress lockset, easy for installation, maintenance easily; Utilize handle to open and close latch, moment is little, startup is light and handy.Simultaneously, latch (keyed end) all designs in door leaf inside, and antitheft, uprising power damage capability is strong.
Below in conjunction with drawings and Examples this real novel anti-theft door is further described.
Fig. 1 is the structural representation of the utility model embodiment security door.
Fig. 2 is that the A of the utility model embodiment security door is to the rotational structure schematic diagram.
With reference to Fig. 1, Fig. 2.Security door is by door leaf 10, doorframe 11 and be installed in bolt-type pin tumbler lock 12 on the door leaf 10 etc. and form.The outer block 1 of lock box is stretched out in one of the dead bolt of door lock 12 inner bottom welding, and when opening and closing door lock, this block 1 can be done horizontal linear with dead bolt and move back and forth.In door leaf inside below the door lock 100MM~150MM place, the rotating disk 3 of side in the outer garden is housed, welding (riveted joint) two rotating shafts 4 on the rotating disk 3 edge axial directions, these two rotating shafts 4 are used to connect upper and lower two connecting rods 5; Square hole is inserted with handle 6 in the rotating disk 3, and can do 90 degree and radially rotate; Radially rotating of rotating disk 3 by the 4 pulling connecting rods of the rotating shaft on the rotating disk 3,5 upper and lower rectilinear motions; In door leaf 10 indoor designs upper and lower two place's latch 2 and ">" type cranks 7 are arranged, latch 2 can be done horizontal linear along door leaf 10 edge directions and move back and forth; The other end of connecting rod 5 is connected with the end pivot pin of crank 7, and an end of latch 2 is connected with the pivot pin of the other end of crank 7, and there is a rotating shaft 8 at crank 7 middle parts, and the upper and lower crank 7 that moves through of connecting rod 5 moves horizontally latch 2; Above rotating shaft, latch, pivot pin were movingly with being connected of hole; Last connecting rod 5 with block 1 corresponding position on a connecting rod block 9 is housed.
Twisting handle 6 rotates rotating disk 3, rotating disk 3 radially rotate by the rotating shaft on the rotating disk 34 make upper and lower connecting rod 5 respectively downwards with move upward, moving up and down of connecting rod 5 makes latch 2 stretch out door leaf 10 by crank 7, inserts doorframe 11, connecting rod 5 is descending on this moment.When locking a door, block 1 is along with dead bolt moves horizontally to the door leaf edge direction, and block 1 blocks connecting rod block 9, and connecting rod 5 positions are sold surely can not be up, thereby pins latch 2.When opening door lock 12, block 1 is done horizontal movement with dead bolt in the other direction to door leaf edge, avoids connecting rod block 9, at this moment, can twist handle 6, makes latch 2 withdrawal door leafs 10, and door can be opened.
When adopting the security door of outwards opening door leaf,, easily be damaged because door hinge is exposed to outdoors.Can increase the latch position of the door leaf edge of door lock direction and hinge direction.Promptly also be provided with the latch same with the door lock limit in door leaf hinge edge direction, two pairs of latches are done reciprocal moving horizontally simultaneously, promptly stretch out door leaf simultaneously and insert doorframe or the door leaf of retraction simultaneously, can prevent to destroy hinge and open door leaf.
