Embodiment Construction

[0028] Combine below Figure 1 to Figure 8 The present invention is further described.

[0029] Such as figure 1 , image 3 , Figure 4 As shown, the ear 17 is welded and fixed with the door frame buckle edge 16 of the door frame 1, and the ear jack 18 is coaxial with the door frame jack 15. The end of the ear 17 is arc-shaped, and the ear 17 is parallel to the door frame 1 , and the opening direction of the ear gap 19 formed by the two faces outside the door.

[0030] There are three ways to fix the ear 17 and the door frame buckle edge 16: the first one, such as image 3 As shown, the ear 17 is directly welded on the buckle edge 16 of the door frame; the second type, such as Figure 5 As shown, before welding, the lug 17 is made into an L shape with the length unchanged, and a long hole is opened at the welding place, and the tail end of the lug 17 is inserted into the long hole and then welded from the inside of the door frame 1; the third , the ear 17 is lengthened,...

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 ...
