Abstract

The utility model relates to an anti-pry door, particularly an anti-pry door capable of simultaneously locking and opening a door on different directions, and the utility model comprises a door body and a door lock. The door lock has lock bolts doing linear motions following the rotation of a key, a driving rack connected and linked with the lock bolts is arranged on the door and is engaged with a gear arranged on the door body, and the gear is also engaged with a sliding rack whose end is provided with a lock bolt capable of being inserted in a door frame. The utility model adopts the lock bolts linked with each other to lock the door on the upper, the lower and the side directions of the door and has good anti-pry performance.

Description

Anti-forcing open the door

The utility model relates to a kind of anti-forcing open the door, and especially can simultaneously the anti-of door locking or unlatching be forced open the door in different directions.

Anti-forcing open the door of the prior art generally is equiped with the lock of tongue with lock, and the dead bolt that it moves by the straight line with key turns inserts on the doorframe maintenance is closed.But, this anti-force open the door just by dead bolt on a direction of door with the door locking, thereby its pick-proof poor-performing.

The purpose of this utility model is exactly to provide a kind of at the problems referred to above to have the anti-of better pick-proof performance and force open the door.

The technical solution of the utility model is, a kind of anti-forcing open the door, comprise a body and door lock, door lock has the dead bolt that straight line moves with key turns, its key is to be provided with dead bolt to be connected also and the driving rack of its interlock, driving rack is meshed with gear on being located at a body, described gear also with the sliding rack engagement, the sliding rack end is provided with the locking bolt that can insert on the doorframe.

Above-mentioned sliding rack is divided into sliding rack and lower slider tooth bar, and they are distributed in the gear both sides, and is meshed with gear respectively.

And the set locking bolt in sliding rack end is 1～5.

And gear was formed by concentric connection of two toothed discs, and driving rack is meshed with a toothed disc, and sliding rack is meshed with another toothed disc.

The utility model since adopt the above-mentioned locking bolt more than two that links on the different directions of door with the door locking, thereby its pick-proof performance is good.

Below in conjunction with accompanying drawing the utility model is described in further detail.

Fig. 1 is a structural representation of the present utility model;

Fig. 2 is the A-A partial view of Fig. 1;

A-A partial view when Fig. 3 adopts the toothed disc form of structure of concentric connection for Fig. 1;

Fig. 4 is provided with the partial view of a plurality of locking bolts in the sliding rack end for the utility model.

Referring to Fig. 1～Fig. 4, the utility model comprises a body 1 and door lock 2, and door lock 2 has the dead bolt 3 that straight line moves with key turns, and door body 1 is provided with the pinion and rack that is made of driving rack 8, gear 11 and sliding rack 6,9.Driving rack 8 and sliding rack 6,9 are provided with in vertical direction and mesh with gear 11 respectively; Driving rack 8 is connected with dead bolt 3 (as connect firmly or hinged), and sliding rack 6,9 ends are fixedly connected with the locking bolt 5,10 that can insert on the doorframe 4.Driving rack 8 and sliding rack 6,9 are spacing by the guiding device 7 (as guide pad 7 or guide groove) of door on the body 1 respectively, when dead bolt 3 straight lines move, driving rack 8 and sliding rack 6,9 be driven and under guiding device 7 effects straight line move.

Lock simultaneously for upper and lower, three directions of side that can make door, the utility model can be provided with two parallel reverse sliding racks: go up sliding rack 6 and lower slider tooth bar 9, they are distributed in gear 11 both sides, and are meshed with gear 11 respectively.Last sliding rack 6 and lower slider tooth bar 9 ends are equipped with locking bolt 5,10.Certainly, if require the more firm of door lock, a plurality of locking bolts can and be established in sliding rack 6,9 ends.Under the prerequisite that does not influence the utility model work, the form of structure of gear 11 also can be made appropriate change, and as two toothed discs 12,13 are connected with one heart, driving rack 8, last sliding rack 6, lower slider tooth bar 9 mesh with toothed disc 12,13 respectively.

When the utility model is locked, with key turns dead bolt 3 is entered in the doorframe 4, when dead bolt 3 moves, the driving rack 8 that is connected with dead bolt 3 moves and driven gear 11 rotations along guiding device 7 straight lines, gear 11 is passed to sliding rack 6,9 with motion and is made it to move and then drive locking bolt 5,10 as straight line and enter in the doorframe 4, makes upper and lower, three direction lockings of side of door.It is similar to unblank and lock, and makes dead bolt 3 withdraw from doorframe 4 with key, and the motion of dead bolt 3 is passed to sliding rack 6,9 through driving rack 8, gear 11 withdraws from locking bolt 5,10 and dead bolt 3 synchronously.

The utility model makes it to be synchronized with the movement with dead bolt 3 by the locking bolt 5,10 that the motion of dead bolt 3 is passed to other direction through mechanical drive mode, thereby reaches the purpose of multi-direction while latching door.Because mechanical drive mode is a lot, thereby the utility model also can adopt mechanical drive mode commonly used to carry out simple combination to substitute above-mentioned transmission mechanism and finish block action of the present utility model.
