Double-insertion type antitheft door

Abstract

The invention discloses a double-insertion type antitheft door and relates to the field of antitheft safety doors. The double-insertion type antitheft door is mainly characterized in that an insertion lug is arranged at the position, corresponding to each doorframe insertion hole, of a doorframe buckled edge, an insertion lug gap is formed between each insertion lug and a doorframe, a double-insertion plate is arranged at the position, closely neighboring a door leaf side edge, inside the door leaf, the double-insertion plate is provided with liner plates in the mode that each liner plate corresponds to the corresponding insertion hole in the doorframe, a narrow-slit type insertion hole is formed between each liner plate and the double-insertion plate, the side edge of a panel inside the door leaf is provided with rectangular insertion holes in the mode that each rectangular insertion hole corresponds to the corresponding narrow-slit type insertion hole, the insertion lugs, the door leaf side edge, the double-insertion plate and the liner plates are each provided with an insertion hole in the mode of corresponding to the doorframe insertion holes, the five insertion holes which are correspondingly formed constitute a group, after the door leaf is closed, the insertion lugs are inserted into the rectangular insertion holes and the narrow-slit type insertion holes, the double-insertion plate is also inserted into the insertion lug gaps, the five insertion holes are all coaxial, lock tongues are inserted into the five concentric insertion holes correspondingly and used for locking the antitheft door, and the double-insertion type antitheft door is resistant to unclenching and damage.

Description

technical field [0001] The invention relates to the field of anti-theft safety doors, in particular to a double-insert anti-theft door. Background technique [0002] The anti-theft door is mainly composed of a door frame, a door leaf, and a locking mechanism, wherein the locking mechanism includes a lockset, a transmission member, a dead bolt or a locking bolt. The lock includes a driving device, and the driving device is divided into a lock cylinder driving method, a handle driving method, and an electric driving method according to different execution methods. There are several door frame sockets on the door frame, and the lock driving device drives the deadbolt and the lock bolt to insert or extract from the door frame sockets through the transmission parts, so as to complete the closing or opening of the anti-theft door. [0003] The disadvantage of the lock cylinder driving method is that the key is overburdened, that is, the key suffers too much resistance during the ...

AI Technical Summary

Problems solved by technology

The above-mentioned locking mechanisms all increase the running resistance, reduce the mechanical strength of some parts, and at the same time, the overall structure is complicated, the cost is increased, and the stability and reliability are not ideal.
