Description

A kind of anti-picking device of security door

Technical field:

The utility model relates to a kind of door lock assembly of haberdashery and hardware class, and is especially relevant with a kind of anti-picking device of security door.

Background technology:

The doorframe and the door leaf of common in the market security door are pressed into by steel plate, close its doorframe and door leaf applying behind the door, between door leaf and doorframe, leave the gap, although have theftproof lock to insert locking at door leaf and doorframe junction, but the dead bolt that inserts lockset with ripping bar when stealer is easy to make the distortion of doorframe and door leaf during with the lock latched position, causes the disengaging of dead bolt and lock and doorframe, security door is pried open easily, greatly reduces theftproof performance.

Technical scheme:

The utility model provides a kind of anti-picking device of security door, and it is simple in structure, can improve the pick-proof ability of security door greatly, and relative cost is lower.

For reaching above-mentioned purpose, the utility model adopts following technical scheme:

A kind of anti-picking device of security door, comprise: antitheft door leaf, anti-theft door frame and lockset, the end of the side panel that described antitheft door leaf and doorframe are fitted inwardly protrudes out a fin, be provided with a groove with described fin correspondence position on the anti-theft door frame, described fin is just stretched in the groove, and described lockset is arranged on the inside at fin and groove fit place.

The end of the side panel of the described antitheft door leaf gusset that stretches out in addition is attached on the anti-theft door frame.

Extend a thin plate before the side panel lateral of described external door leaf, the end of this thin plate inwardly protrudes out a fin, and the doorframe that is mated forms a groove at the fin place, and fin inserts in the groove, and described lockset is arranged on the inside at fin and groove fit place.

The end of side panel of the door leaf fin that directly stretches out in described, the doorframe place of being mated is provided with a groove, and in the fin insertion groove, described lockset is arranged on the inside at fin and groove fit place.

The end of described gusset is square or arc.

Adopt technique scheme, because the lockset of interior external door all is arranged on the inside at fin and groove fit place, the thief can't prize lockset, and it is not only simple in structure, easy to operate, and the pick-proof ability improves greatly, and is safe and reliable.
