Abstract

The utility model relates to a safety theft-proof door made of steel, which is arranged on the outer side of an original house door. The utility model is characterized in that a dowel is respectively arranged on an upper side and a lower side of the doorframe hinge; pin holes corresponding to the dowel are respectively arranged on the upper side and the lower side of the doorframe hinge. When the door is closed, the end part of the dowel is inserted into the pin hole. At least two nuts are respectively welded on both sides of the doorframe, which is used for fixing the doorframe on an original doorframe; an alarm unit is arranged in an interlayer in the middle of the door leaf; the safety theft-proof performance of the utility model can be improved.

Description

Safety theft-proof door

The utility model belongs to the security door technical field.

The security door that the existing iron and steel that is installed in the former door outside is made, as the patent No. 88215998.4 " iron hurdle security door ", though have the effect of riot burglar, but remain in weak point: the one, its hinge that connects door leaf and doorframe easily is damaged, door leaf is come off, the 2nd, its doorframe is connected with the bolt of former doorframe by break-through two doorframes, and this bolt easily goes to pot, doorframe is come off together with door leaf, thereby reduce anti-theft effect.

The purpose of this utility model provides the good steel safety anti-theft door of the strong theftproof performance of a kind of anti-destructive power, is used to be installed in the outside of former door, to improve unit and resident's safety.

The utility model is the improvement to existing steel safety anti-theft door, it has doorframe and is installed in door leaf on the doorframe by hinge, its door leaf comprises by the fan frame of section steel manufacture and is installed in the door grid of fanning on the frame, there is an interlayer that is made of steel plate at the middle part of door leaf, door lock is installed in the interlayer, on doorframe, has the lock box corresponding with the Door-lock bolt position.Its improvements are, the both sides up and down of the hinge on doorframe respectively are equipped with a dowel, the both sides up and down of the hinge on the door leaf fan frame respectively have one with doorframe on the corresponding dowel hole in dowel position, the dowel end is just in time inserted in the dowel hole during door closure; Respectively be welded with at least two and the parallel plane dark nut of doorframe in the both sides of doorframe, it cooperates the outside that this doorframe is fixed on former doorframe with bolt.

Safety anti-theft door after the above-mentioned improvement, anti-destructive power is strong, even hinge is destroyed, dowel still can make the door leaf location, again because of the dark nut that is used for fixing doorframe is welded on the doorframe, this doorframe can't be separated with former doorframe from the outside, thereby theftproof performance is strong.

Accompanying drawing has provided an embodiment of the present utility model, wherein:

Fig. 1 is a door leaf inside structure schematic diagram;

Fig. 2 is a door leaf outboard structure schematic diagram;

Fig. 3 is the sash structure schematic diagram;

Fig. 4 is the former doorframe connection diagram in this doorframe and room;

Fig. 5 is the installation schematic diagram of dowel;

Fig. 6 is the warning device electrical schematic diagram.

Doorframe (11) is welded by the Z-shape steel square tube.Doorframe (11) is gone up and in the both sides up and down of hinge (4) dowel (12) is installed respectively.Respectively be welded with three special-shaped nuts (13) in the both sides of doorframe, this nut (13) cooperates with bolt (15), this doorframe (11) is fixed on the former doorframe (14) in room.Door leaf comprises the fan frame (1) that is welded into by the T-steel square tube and is fixed on the door grid of fanning on the frame (1) (2) by reinforcing bar or steel pipe manufacturing, there is an interlayer (7) of being made by steel plate at the middle part of door leaf, omnibearing anti-theft lock (6) is installed in this interlayer (7), this lockset has dead bolt (10) and last safety cock (8) and safety cock (9) down, goes up and dead bolt (10) corresponding position, position has lock box at doorframe (11).The upper and lower sides of door leaf fan frame (1) hinge (4) respectively have one with doorframe on the corresponding dowel hole (3) in dowel (12) position, when door leaf is closed, in the end of dowel (12) the insertion dowel hole (3).In the interlayer (7) of door leaf, warning device (5) is installed also, it comprises a music integrated block IC and a loudspeaker Y, battery-powered, lock core is installed in an interior spring leaf of doorframe lock box as a constant close contact K2 in its circuit as a K switch 1 in its circuit, and its principle is, when state that door lock is in out, K1 disconnects, K2 closure, circuit breaker; When door is closed, when door lock is locked, K switch 1 closure of lock core control, and dead bolt (10) backs down the spring leaf in the lock box, and K2 is disconnected, alarm (5) is not worked; But prized when door lock, when door leaf and doorframe have certain interval, during dead bolt (10) retraction, make spring leaf in the lock box closing of circuit, i.e. K2 closure, so the time K1 be closed, thereby alarm (5) works, thereby improved the safe antitheft effect of this door.
