Abstract

The utility model relates to an anti-theft door leaf provided with an anti-theft piece. A current anti-theft door of door leaves is provided with a door leaf cover opening. The door leaf cover and a door leaf is structured as an integration. An outer board of the door leaf is extended outwardly and is folded into a cover opening shaped like a right angle or a rectangle which is weak and thin and has a bad anti-theft performance. The anti-theft door leaf provided with an anti-theft piece of the utility model comprises an inner door board and an outer door board which is characterized in that the inner door board and the outer door board are respectively provided with a lower folding and an upper folding at side edges and an anti-theft piece provided with an inner cavity shaped like a ''L'' which is insertedly connected between the upper folding and the lower folding. Two sides of the anti-theft piece are provided with an inner folding which closely matches with the upper folding and the lower folding, whereof an upper end is shaped like a rectangle which functions as a door leaf cover opening. The anti-theft piece is integrately formed which has the advantages of stable structure, difficult transformation under outside force, improving of the anti-theft function of the door leaf and convenient folding and processing because of a small surface area of the anti-theft piece.

Description

The antitheft door leaf of band pick-proof spare

[technical field]

The utility model relates to security door, particularly a kind of antitheft door leaf with pick-proof spare.

[background technology]

Existing security door door leaf for pick-proof, is typically provided with door leaf lid mouth, and it can block the slit between door leaf and the doorframe, has certain pick-proof effect.Door leaf lid mouth is an integrative-structure with door leaf, by the outside plate of door leaf to extension, be converted into the right-angle side edge, the door-plate edge forms the lid mouth with edge banding machine to right-angle side along carrying out the edge sealing seaming, this lid mouth is to be formed by the steel plate that is close together, be subjected to the restriction of the inside and outside slab material thickness of door leaf, the lid mouth is therefore thiner, the pick-proof poor performance as strengthening the intensity of lid mouth, must be selected thicker steel for use, but because the area of the inside and outside plate of door leaf is far longer than the area of lid mouth, certainly will improve the cost of door leaf, uneconomical, and also difficulty of processing is big.

The design of another kind of lid mouthful be with the door leaf outside plate to extension, be converted into rectangular-shapedly, its edge links to each other with the door leaf side by filler rod and forms lid mouthful, but under external force prized, deformation easily took place scarf, the pick-proof performance still can't improve.As not adopting filler rod to link to each other, and change welding into, can improve pick-proof, but influence the outward appearance of door leaf, and can have the slit during door leaf closure and between doorframe, can't fit.In addition, the large-area like this roll of steel plate of door-plate is converted into complicated shape, is subjected to the restriction of present equipment, can't realize.

[utility model content]

The technical problems to be solved in the utility model is to overcome the technological deficiency that existing product exists, a kind of antitheft door leaf with pick-proof spare is provided, and the pick-proof spare of pegging graft on the door leaf main body improves a lot the pick-proof performance of antitheft door leaf, and pick-proof spare is made separately, and is easy to process.

The technical scheme that the utility model is taked is: the antitheft door leaf of band pick-proof spare, comprise internal hilar plate and external door panel, the side that is characterized in internal hilar plate and external door panel is respectively equipped with lower hem and upper hem, the L-shaped pick-proof spare of an inner chamber of pegging graft between upper hem and the lower hem.The both sides of pick-proof spare are provided with the interior flanging with upper hem and lower hem close fit.Upper and lower flanging and interior flanging match, and only play interconnect function, and do not have tamper-resistant function.Pick-proof spare is plugged on the side of inside and outside door-plate, and the inner chamber upper end of pick-proof spare is a rectangle, and Stability Analysis of Structures is difficult for deformation under external force, play the pick-proof effect of door leaf lid mouth.Because the area of pick-proof spare is little, convolution is easy to process.

Further perfect as to technique scheme is provided with the lining frame between internal hilar plate and external door panel, the inner chamber upper end of pick-proof spare is provided with reinforcing rib, and reinforcing rib is fixed on the lining frame intensity with further enhancing pick-proof spare.

The utility model passes through at the L-shaped pick-proof spare of an inner chamber of pegging graft between the lower hem on the inside and outside door-plate side.The inner chamber upper end of pick-proof spare is a rectangle, plays the pick-proof effect of door leaf lid mouth, and pick-proof spare is a global formation, Stability Analysis of Structures, and the inner chamber of pick-proof spare can play conduction to external force, thereby is difficult for deformation under external force, has improved tamper-resistant function.Because pick-proof spare is parts, processing separately, its material can be selected thicker steel for use, further improves intensity, and needn't be subjected to the restriction of door-plate steel, and the area of pick-proof spare is little, and convolution is easy to process.

[specific embodiment]

Below in conjunction with accompanying drawing, the utility model is further described.As shown in Figure 3, the antitheft door leaf of band pick-proof spare, comprise internal hilar plate 1 and external door panel 2, side in internal hilar plate 1 and external door panel 2 is respectively equipped with lower hem 4 and upper hem 3, upper and lower flanging is the clasp shape that convolution forms, the both sides of the pick-proof spare 5 that inner chamber is L-shaped are provided with interior flanging 6, and interior flanging 6 is the clasp shape that matches with upper and lower flanging, and pick-proof spare 5 is plugged between upper hem 3 and the lower hem 4 by interior flanging 6.Last lower hem and interior flanging play interconnect function, and pick-proof spare 5 is closely linked to each other with door leaf.

For further strengthening the pick-proof ability, be provided with reinforcing rib 7 in the inner chamber upper end of pick-proof spare 5, reinforcing rib is fixed on the lining frame 8 between internal hilar plate 1 and the external door panel 2.

Fluted 9 on the pick-proof spare 5, groove weld is connected on the lining frame 8.

Pick-proof spare 5 can be installed in one side of door leaf or polygon, also can be installed in four limits of door leaf.
