Abstract

The utility model relates to a metal anti-theft door with a door frame and a door leaf for household which comprises the door frame and the door leaf, wherein, the edge on one side of the door leaf has a hinge to connect with the door frame, while a door lock is arranged on the edge of the other side. A pressing plate is arranged outside the door lock. A concave slot is arranged on the edge of the door leaf to correspond to the pressing plate. The pressing plate is inlayed into the concave slot. Because the pressing plate is inlayed into the concave slot, no special requirement is needed for hole bias and size of the lock core mounting hole and the screw mounting hole, thereby greatly reducing the mounting difficulty of door lock without no looseness of the door lock. The outer surface of the pressing plate is in the same plane as the surface of the door leaf; therefore the gap is smaller and shape is beautiful. The anti-theft performance is improved. The pressing plate can be welded with the wall of the concave slot; furthermore, the welded connector is not exposed outside without affecting the shape of the door lock and the door leaf.

Description

A kind of metal anti-theft door

Technical field

The utility model relates to a kind of family expenses metal anti-theft door that comprises doorframe and door leaf.

Background technology

Some holes are bored in the zone that metal anti-theft door needs door lock is installed on door leaf when door lock is installed, and core installing hole, screw mounting hole etc. are wherein arranged, the accurate contraposition of each Kong Douying, and it is firm that door lock is installed.But when boring, all deviation can occur usually, need strengthen the installing hole aperture for this reason, also may cause the door leaf subscription rate when deviation is excessive.Because the increasing of installing hole just occurs after door lock is installed becoming flexible the anti-theft security performance of the attractive in appearance and door lock of influence door easily; On the other hand, because the door lock pressing plate places door leaf plate face to be easy to produce the slit, owing to reason such as attractive in appearance can't be welded, the pick-proof performance is lower again.More than two aspect problem prior aries still unresolved.

The utility model content

The metal anti-theft door that provides a kind of door lock firm, attractive in appearance and easy for installation is provided the purpose of this utility model.

For achieving the above object, metal anti-theft door of the present utility model comprises doorframe, door leaf, one lateral edges of door leaf 1 has hinge to connect doorframe, there is door lock 3 at opposite side edge 2, there is pressing plate 6 in the outside of this door lock 3, door leaf edge 2 has and this pressing plate 6 profile corresponding grooves 4, and this pressing plate 6 embeds in this groove 4.

Described hinge can be to be Built-in hinge.

The utility model is because in the pressing plate embedding groove, biased difference in hole and size to core installing hole, screw mounting hole etc. do not have special requirement, the difficulty that door lock is installed reduces greatly, and it is loosening to be difficult for generation, and the pressing plate external surface becomes same plane with the door leaf surface, the slit is little, attractive in appearance, the pick-proof performance is also strengthened, and also can weld between pressing plate and groove walls, the welding rear port does not expose, and does not influence the attractive in appearance of door lock and door leaf.

Embodiment

Metal anti-theft door of the present utility model comprises doorframe, door leaf 1, doorframe is loaded in the wall, as shown in Figure 1, a lateral edges 2 of door leaf 1 is connected with doorframe by Built-in hinge, and opposite side has door lock 3, door lock 3 has pressing plate 6, as Fig. 2, shown in Figure 3, door leaf 1 has the groove 4 of a punching press in the zone that door lock is installed, core installing hole 5 is arranged on the groove 4, the shape of groove 4 is corresponding with the profile phase of pressing plate 6, and the degree of depth of groove 4 is identical with the height of pressing plate 6.As Fig. 4, shown in Figure 5, when door lock 3 was installed, pressing plate 6 embedded in the groove 4.Because pressing plate 6 firmly places groove 4, big and the deviation of core installing hole 5 and screw mounting hole does not influence the firm degree of door lock, thereby difficulty of construction reduces greatly, the surface that rear fender 6 surfaces and door leaf edge 2 be installed is with one side, the interface slit is little between pressing plate 6 and the door leaf 1, seem attractive in appearance, and be difficult to pry open that the pick-proof performance improves.Can also between the sidewall of groove walls and pressing plate 6, be welded to each other, pressing plate more firmly is fixed in the door leaf.Because welding junction is positioned at groove, the weldering line of welding is not seen on the door leaf surface, thereby keeps the attractive in appearance of door leaf and door lock.
