Referring to Fig. 2, Fig. 3, Fig. 4, the utility model is mainly by lamina rara externa 9, middle level steel plate 13, inner plating 11, edge cover strip 10 and lock 4 and form, design has groove 17 on the middle level steel plate 13, middle level steel plate 13 cross sectional shapes among this figure are side tooth profile, can finalize the design by turning back form, and all sticks with glue between lamina rara externa 9 and middle level steel plate 13 and middle level steel plate 13 and the inner plating 11 to connect, and lamina rara externa 9 can adopt on-deformable U.S. access doors panel, inner plating 11 can adopt common three layers of veneer, to reduce cost; Edge cover strip 10 can stick with glue be connected on the door around, the lock 4 (safety locks) can be fixed by bolts to the door a side; Strengthen and cushioning effect for rising, also be filled with net form batten 16 in the groove 17 of middle level steel plate 13; Groove 17 two ends and middle part at middle level steel plate 13 are fixed with wooden unit 14, simultaneously, for hinge 18 (Fig. 5) being installed and being locked 4, are fixed with the long wooden unit 12 of whole piece in the groove 17 on middle level steel plate 13 both sides; Lockhole 15 can be opened at the right and left, so that the user selects opening direction.

In addition, this structure is equally applicable to width, and promptly the structure of middle level steel plate 13 can turn over 90 ° of uses.

Referring to Fig. 5, hinge 18 can be connected with edge cover strip 10, middle level steel plate 13 and long wooden unit 12 by screw 19.

Referring to Fig. 6, the cross sectional shape of middle level steel plate 13 can also be that side tooth profile adds rectangle, and optimum shape is a both sides side tooth profile and middle be rectangle, and groove 17 is also arranged on it.

In addition, for playing anti-fire action, this two-in-one security door can plate fire proofing material on the surface, and on the timber surface of inside fireprotection layer is set.

The utility model compared with prior art has the following advantages: 1, structural design is closed Reason, easy to use, reliable, floor space is little, is difficult for collision when opening the door between corridor; 2, In the identical situation of theftproof performance, overall cost is low, uses economy, simultaneously, and beautiful outline form See generous; 3, two-in-one rear branch family and the antitheft dual-use function of having played equally.
