Description

Practical theft-proof door

The utility model provides a kind of Nover practical security door, belongs to the house door, and it increases by one Bidirectional bolt lock formed on general door, and it is simple in structure, special Nover practical, good anti-theft effect.

At present, the security door that is adopted all is to have only a door lock, and therefore, anti-theft effect is not good.So far, have no precedent all security doors in pin jail of two lock handle three limits of employing.

The purpose of this utility model is to overcome existing security door and has only a lock, the weak point that anti-theft effect is not good, thus provide a kind of simple in structure, low price, easy to use, the Nover practical security door of good anti-theft effect uses during for building.

The utility model is realized by following approach:

The utility model includes door-plate, hinge, door lock, the Bidirectional bolt lock, parts such as handle, one side at said door-plate is fixed on the door-plate activity on the doorframe with at least two pairs of hinges, and the correct position in the middle part of its one side, opposite is established a door lock, make its with doorframe on the snap close of correct position coincide and to cooperate, establishing a Bidirectional bolt at the correct position of door-plate then locks, its locking bar is coincide with the snap close of doorframe top and ground correct position to be cooperated, again the correct position of handle is established the hole that a fore shaft of locking with Bidirectional bolt coincide, and with this borehole jack on fore shaft, handle is fixed on the door-plate.

Correct position at said handle is respectively equipped with a handgrip and the cover plate that activity is fixing, and this cover plate coincide and covers set hole on handle.Handle and set handgrip, cover plate can constitute animal head.Said door-plate can be made individual layer or double-decker with timber, steel, if double-decker, locking bar be located at two-layer between.Correct position can be established window on door-plate.Said door lock can be Lock with double safety guard or three safety locks.

During use, can use door lock separately, lock without Bidirectional bolt.Also but door lock and Bidirectional bolt lock uses simultaneously, four limits of door-plate all is firmly fastened on doorframe, thereby reaches reliable antitheft effect.And can accomplish about two sides to pin and antitheft, so function of use is complete.

The utility model describes in detail below in conjunction with accompanying drawing embodiment:

The utility model embodiment includes door-plate 1, hinge 2, door lock 3, also include the Bidirectional bolt lock 4 and more than 6 parts of shaking hands, one side at said door-plate 1 is fixed on door-plate 1 activity on the doorframe with two pairs of hinges 2, and on its opposite on one side middle part correct position is established a dual fail-safe door lock 3, make its with doorframe on the snap close of correct position coincide and to cooperate, establish the Bidirectional bolt lock 4 that a Guangdong kind Yu Heng cutting edge of a knife or a sword Lock Factory produces at the correct position of door-plate 1 then, its locking bar 5 is coincide with the snap close of doorframe top and ground correct position to be cooperated, to shake hands again 6 correct position is established the hole that a fore shaft 8 with Bidirectional bolt lock 4 coincide, and with this borehole jack on fore shaft 8, handle 6 is fixed on the door-plate 1.

Be provided with a handgrip 9 in the bottom of said handle 6, fix a circular cover 7 with the small hinge activity above handgrip 9, this cover plate 7 coincide and covers set hole on handle 6.

Said door-plate (1) is a single layer structure.

The utility model contrast prior art has following advantage:

1, the utility model is only set up a two-way plug lock in prior art, thereby simple in structure, low price;

When 2, using the utility model, door-plate four limits all can be firmly fastened on doorframe, thereby anti-theft effect is splendid;

When 3, using the utility model, can use separately door lock, without the two-way plug lock, but also door lock and two-way plug lock use simultaneously. Both can be at the room external lock, also can be at the room internal lock, therefore very easy to use;

4, the utility model Bidirectional bolt is locked a door outer fore shaft owing to covered by the cover plate on the handle, therefore, is difficult for finding to have hidden characteristics.
