Abstract

The utility model relates to a four-azimuth locking anti-theft door, a reinforced plate is arranged in a front panel; a protective cover for a driving disk is arranged at the back of the panel; a four-azimuth driving disk is arranged in the cover; the driving disk is connected four pulling sheets respectively hinged with a connecting rod; the connecting rod is hinged with a bolt; a self-locking device for a spring is arranged on the position of the bolt. A positioning bolt on one side of a hinge for a wing leaf of the structure is converted into a movable blot; the length is increased; a bolt hole is reduced; the capability for resisting prying can be reinforced. When a lock device and a driving device are broken, the self-locking device of a spring still can tightly lock the wing leaf; the anti-theft capability can be effectively improved.

Description

Position, four directions locking security door

The utility model relates to door, the window with antitheft purposes.

General security door, its wing constitutes skeleton by two crossbeams of four frames and middle part.Two frames up and down and a side frame of wing are provided with the bolt-type keeper, be provided with front panel and rear board between two crossbeams, form a closure casing, Built-in lock tool and three-dimensional link gear, this link gear is by a bull wheel that is connected with door handle, and hinged 3 pulling-on pieces constitute at the bull wheel edge, 3 hinged 3 connecting rods of pulling-on piece difference, can 3 connecting rods directly as latch, also can patch pin in addition.Turn the handle and can control stretching out or withdrawing of 3 direction latches, the lockset in the closure casing can not rotate door handle the bull wheel locking, and this moment, three latches entered in the pin-and-hole of steel door frame, played antitheft effect.Existing security door is provided with fixed alignment pin being positioned on the side frame that hinge is installed, and after door closed, this pin entered in the pin-and-hole of doorframe, plays a role to preventing to be forced open the door to destroy by door hinge one side.But this kind structure enters pin-and-hole smoothly in order to make alignment pin at closing time, the pin-and-hole diameter is more many greatly than alignment pin diameter, and alignment pin length also very short (maximum 15 millimeters) greatly reduces the pick-proof performance of security door hinge one side, and security door is easily pried open from this.Existing anti-security door when connecting rod or link gear by by after bad, door can be opened, and loses antitheft effect.

The purpose of this utility model provides position, a kind of four directions locking security door, by the latch in 4 orientation of link gear driving, makes to be positioned at the latch that hinge one flank is fanned can be had than long, and the pin-and-hole on the doorframe and this latch have matched well, strengthen the pick-proof performance of this side; Connecting rod outer end mortise lock portion is provided with the spring self-locking mechanism, and connecting rod or link gear are gone to pot, and this mechanism still makes latch be among the pin-and-hole of doorframe, can't open security door, guarantees its antitheft effect.

For achieving the above object, the utility model is taked following design scheme: open a side near wing and establish stiffener between two crossbeams of wing middle part, this stiffener places within the header board, and it is affixed with 2 crossbeams and side frame, the affixed driving-disc guard shield in middle part, stiffener back, position, interior dress four directions driving-disc, the driving shaft of this dish passes the axis hole of stiffener and driving-disc guard shield, the driving-disc outer rim connects 4 pulling-on pieces and is hinged with 4 connecting rods respectively, each connecting rod outer end hinged latch, the latch position is provided with the spring self-locking mechanism.

Position, the utility model four directions locking security door changes existing three-dimensional link gear into four directions position driving locking mechanism, make 4 frames up and down of wing be equipped with the movable latch of being controlled by driving-disc, the fixed location lock that hinge one side just will be installed becomes movable latch.Avoided this alignment pin length to be restricted, the excessive low shortcoming of bringing of pick-proof performance of pin-and-hole.Therefore, this place can adopt long latch, and pin-and-hole also can have coupling preferably with latch, has improved the pick-proof performance of security door hinge one side, has solved the problem that this side is easily pried open.The utility model is provided with the spring self-locking mechanism at the latch position, and the latch position is subjected to the effect of spring, remains to the power of stretching out outdoors.Only turn the handle, drive driving-disc and rotate, affect latch by pulling-on piece, connecting rod, when overcoming the elastic force of spring, latch is just withdrawn in the door, and after driving-disc was by the door lock locking, latch can insert in the pin-and-hole of doorframe firmly; When door lock, driving-disc destroyed, even the pulling-on piece connecting rod destroyed after, latch is by the effect of spring.Still can not return Men Tizhong, security door can't be opened still firmly by locking, does not still lose its antitheft effect.The utility model has increased stiffener, and its thickness is bigger, has installed the driving-disc protective cover additional, plays a role to having improved tamper-proof unlatching.

The utility model is described in further detail below in conjunction with accompanying drawing.

Fig. 2 is latch, spring self-locking mechanism schematic diagram

Fig. 3 is the side cut-away view at door handle position

As Fig. 1, shown in Figure 3, this security door is opened a side near wing and is established stiffener 10 between two crossbeams of wing middle part, this stiffener places within the front panel 16, and affixed with 2 crossbeams and side frame, the affixed driving-disc guard shield 8 in middle part, stiffener back, position, interior dress four directions driving-disc 5, the driving shaft 9 of this dish passes the axis hole of stiffener and guard shield, it is hinged with 4 connecting rods 7 respectively that the driving-disc outer rim connects 4 pulling-on pieces 6, each connecting rod outer end hinged latch 4, and the latch position is provided with spring self-locking mechanism 3; Behind lockset 1 locking, driving-disc promptly can not rotate, the thin portion of latch and spring self-locking mechanism as shown in Figure 2, the spring self-locking mechanism can adopt extension spring, its two ends are connected with frame 12 and latch are inner respectively, also can adopt the stage clip structure.In order to strengthen the pick-proof ability of security door, can adopt stacking adapter as shown in the figure, this stacking adapter is provided with a plug housing 11, connection handle 15 is established in the plug housing rear end, connection handle and rod hinge connection, affixed 2 latches of plug housing front end, 2 latches are isometric and pass the pin-and-hole of frame 12; In order more to strengthen the anti-plug ability of latch, can be outside latch suit pin bushing pipe 13, this sleeve pipe is fixed on the frame, also can establish support 14 in addition with fixed sleeving, latch can smooth and easy slip in sleeve.In view of some saboteur is connected on the door handle 17 with longer sleeve pipe, turn the handle to overcome the locking ability of dead bolt with powerful then to driving-disc, latch is retracted in the door, reach the purpose of unlatching, can adopt following scheme to be prevented; Cut out 2 relative brute forces on the outer garden with driving shaft 9 from fault trough 18, this groove trend is axially vertical with driving shaft, and when door handle was subjected to powerful torsion, driving shaft can be fractureed by this groove place, to prevent adopting strong torsion that door is opened.For preventing that metas such as lockset, driving-disc from being destroyed because of front panel is subjected to flame cutting, the utility model is installed the anti-cut plate 19 of stainless steel material in front between plate and the stiffener.
