Description

The double-deck Three-bearing lock of steel security door

The utility model belongs to security door, relates to the double-deck Three-bearing lock of a kind of steel security door specifically.

In the last few years, along with construction industry development, improving constantly of people's lives level, the security door manufacturing technology is constantly progressive, the double-deck fan of steel security door is firm, safe, antitheft with it, sound insulation, ventilation, advantage such as fire-retardant have progressively replaced existing steel simple gate fan security door, yet, blemish in an otherwise perfect thing be at present this commercially available series products also to exist between doorframe and the door leaf slit big, easily pried open and shortcoming such as the theftproof lock theftproof performance is firm not enough, influenced the safety and the anti-theft feature of whole security door.

The utility model purpose is to provide the double-deck Three-bearing lock of a kind of steel security door, and the safety and the anti-theft feature of this security door are further enhanced.

Its formation of the double-deck Three-bearing lock of steel of the present utility model security door comprises interior exterior door frame, interior external door leaf, theftproof lock, handgrip, extensively look eye, door benevolence, the flag-shaped hinge, Pinless hinge with guide member, interior exterior door frame becomes conjoined structure, door leaf welds adult by interior outer panels by inner frame, interior door leaf is filled with shockproof quieter material as envelope nest paper, and folding the making of outer panels on external door leaf unlatching limit covered tape edge, and door leaf was on interior doorframe in Pinless hinge with guide member connected, theftproof lock in it is characterized in that on the door leaf is the Three-bearing lock, and it is made up of main lock and two attached locks with main lock interlock.Be shaped on the groove that the flag-shaped hinge is installed on the above-mentioned external door leaf side, this groove just is complementary with hinge flag-shaped plate size, thickness, side at inside and outside doorframe column is shaped on fixedly pinning, relevant position at interior external door leaf is shaped on locking nail hole, after door leaf cut out, the fixedly pinning on the doorframe just inserted in the locking nail hole on the door leaf.

Compared with prior art, this case security door has following characteristics:

1. on the doorframe, strengthened the theftproof performance of theftproof lock in the Three-bearing theftproof lock firmly is locked in interior door leaf; 2. the flag-shaped plate of the hinge of external door leaf is steady shape installation, has significantly reduced the slit between external door leaf and the exterior door frame; 3. be shaped on fixedly pinning and locking nail hole on doorframe and door leaf fillet, after door leaf cut out, the fixedly pinning on the doorframe just inserted in the locking nail hole on the door leaf, had further strengthened the pick-proof and anti-theft function of security door again.Because this case security door is that the anti-theft security performance is able to further raising in the technical as above characteristics that increased of existing steel dual-layer antitheft door, makes this product be particularly suitable for the user and use.
