Description

Anti-theft door

Security door is a kind of antitheft room Hu Men with safety effect that is used for.

Existing security door all is by doorframe, hollow door-plate, and the latch that is loaded on the door-plate built-in lock, is connected by the turning handle of built-in lock tongue card and with turning handle and passes the door-plate limit is formed.When built-in lock is destroyed, just can rotates turning handle and open latch.And when rotating turning handle, also can destroy dead bolt with bigger power.Particularly when destroying the hinge that exposes between door-plate and the doorframe, door will be opened.

The purpose of this utility model is to provide a kind of security door that can't open door when destroying lock or hinge.

Security door of the present utility model still contains doorframe, hollow door-plate, pass the door-plate limit and the latch that inserts the doorframe pin-and-hole is formed.Between door-plate side and doorframe hinge is housed.Its design feature is: the lockhole that reaches the door-plate outside in the door-plate is equipped with the lock pin lock; Be connected with connecting rod between lock pin lock and the latch; The door-plate side that hinge is housed is fixed with short pin, and the doorframe correspondence has pin-and-hole.Because after lock pin was locked in destroyed lock core, inserted sheet can not be moved yet, just can also guarantee that the pin of latch goes into the state of doorframe pin-and-hole.Under the destroyed situation of hinge, the short pin of closing door still is inserted in the corresponding doorframe pin-and-hole, and door-plate still can not move.So just played effective antitheft effect.

Lock pin lock drives laterally simultaneously in order to make, latch longitudinally, increases anti-theft capability, and angular pole and door-plate are hinged, the slotted hole at angular pole two ends respectively with lateral pin, the vertical rod hinge connection of selling.When the lock pin lock drove lateral pin or vertical pin like this, also interlock was indulged pin or lateral pin.A lock pin is locked lock lateral pin, vertical pin simultaneously.For strengthening door-plate internal intensity and sound-insulating effect, in hollow door-plate, be provided with horizontal bar, and accompany light material.For further antitheft, be convenient to the short time simultaneously and go out to enter, also built-in lock can be housed in addition at door-plate.

Security door of the present utility model compared with the prior art, when destroying lock core and hinge, door still is in the lock state, can avoid theft effectively, has increased the anti-theft capability of door.Simultaneously door-plate can adopt steel plate rolling to be welded, and has increased intensity, and voided layer and be added with the light heat insulation sound insulation materials plays the heat insulating and sound insulating effect.

Accompanying drawing has been represented a kind of security door internal construction of the utility model schematic diagram.This security door by steel doorframe 1, the hollow door-plate 2 of steel, lock pin lock 16, hinge 10, sell 13,18 in length and breadth and form.Be connected with hinge 10 between door-plate 2 sides 19 and the doorframe.Door-plate side at the dress hinge is fixed with short up and down pin 3, and the corresponding doorframe place of short pin has pin-and-hole 4.Lock pin lock 16 is being fixed at the place of taking back, door-plate 2 middle part, and the lock core 6 of lock pin lock exposes from door-plate outer plate surface lockhole.The inserted sheet 5 of lock pin lock is respectively with vertical pin--the connecting rod 15 of upper and lower latch 18 is connected.Upper and lower cotter joint pass respectively door-plate up and down side can insert the pin-and-hole 20 of doorframe upper and lower frames.Right angle type angular pole 14 is hinged with door-plate.The two ends of angular pole have the slotted hole chute, the one end respectively with the connecting rod pin socket of corresponding upper and lower latch, the other end respectively with corresponding lateral pin--horizontal latch 13 connecting rod pin sockets.Two horizontal latches pass the pin-and-hole that the doorframe left frame can be inserted in limit 11, door-plate left side respectively.When the lock core that turns lock pin lock, drive inserted sheet and upper and lower cotter joint, also drive two horizontal latches simultaneously by two angular poles, insert corresponding pin-and-hole or from pin-and-hole, withdraw from.And short up and down pin 3 is to be inserted in the corresponding doorframe pin-and-hole at door closure state.Between the door-plate front and rear panel, be added with horizontal stripe muscle 12 and accompany polyester foam block 17.The common spring lock also is housed in door-plate left side, and when being used for interim inlet/outlet, the lock door also plays the effect of dual fail-safe simultaneously.
