Abstract
The utility model relates to an anti-theft door made of steel, which is characterized in that the surface of a column at the opening edge of a door frame is provided with a groove, and the cover seam edge of an outer panel on the opening edge of a door leaf is provided with a hook, wherein, the hook is matched with the groove on the surface of the column of the door frame. When the door leaf is closed, the hook of the opening cover seam edge of the door leaf is just inserted into the groove on the surface of the column of the door frame. The utility model overcomes the defect in the prior art that the door leaf is easy to pick, and therefore, the anti-theft function of the anti-theft door made of steel is further enhanced.
Description
The utility model belongs to security door, relates to a kind of steel security door specifically.
In the last few years, along with the security door manufacturing technology is constantly progressive, model change is rapid, the steel security door is firm with it, safety, antitheft, advantage such as fire-retardant has progressively replaced existing wooden security door, yet, at present the connection hinge that still exists of commercially available security door is easily cut with the door leaf slit and shortcoming such as is easily pried open, applicant's ZL97247700.4 name is called " steel dual-layer antitheft door " and discloses and open folding the making of limit outer panels with external door leaf and cover tape edge, close the technology in the slit of back existence in order to cover door leaf and doorframe, but tamper-resistant function is not perfect.
The steel security door that provides a kind of tamper-resistant function good is provided the utility model purpose.
Steel security door according to the design of the utility model purpose comprises doorframe, door leaf, theftproof lock, handgrip, extensively look eye, members such as hinge are formed, door leaf is articulated and connected by hinge and doorframe, and door leaf is filled with quieter material by two layers of steel plate bridge joint adult in the door leaf, the doorframe left and right sides is fixing by the gusset piece typing, the unlatching edge column surface that it is characterized in that doorframe is shaped on groove, and the lid tape edge end of the unlatching limit outer panels of door leaf is shaped on crotch, and this crotch and doorframe column surface groove are complementary, when shutting door leaf, the lid tape edge of the unlatching limit outer panels of door leaf is shaped on crotch and just is embedded in the doorframe column surface groove.
Compared with prior art, this case security door is simple and reasonable, the lid tape edge that both can utilize door leaf to open the limit covers door leaf and doorframe is closed the slit that the back exists, but also, the tamper-resistant function of steel security door is strengthened greatly because the crotch that lid tape edge end is shaped on can just be embedded in the doorframe column surface groove.This invention design can be used for existing simple gate frame simple gate fan steel security door, also can be used for the two-door fan steel of existing two-door frame security door.
The utility model exemplary embodiments is to have implemented the technical solution of the utility model at existing steel dual-layer antitheft door.Further describe the utility model below in conjunction with accompanying drawing.
Fig. 1 is the structural representation after known steel dual-layer antitheft door is opened external door leaf.
Fig. 2 is known steel dual-layer antitheft door doorframe and door leaf assembling schematic diagram.
Fig. 3 is doorframe of the present utility model and door leaf assembling schematic diagram.
With reference to shown in Figure 1, known steel dual-layer antitheft door is usually by doorframe 1, external door leaf 2, and interior door leaf 3, theftproof lock 4, handgrip 5, Wide-field mirror 6, hinged 7 members such as grade are formed.
Fig. 2 is known steel dual-layer antitheft door doorframe and door leaf assembling schematic diagram.From figure, know and find out that external door leaf 2 and interior door leaf 3 constitute by two layers of steel plate, two layers of steel plate are by inner frame 8 welding edge adults, fill with 9 noise reductions of envelope nest paper shockproofly therebetween, and door leaf and doorframe are articulated and connected by hinge 7, the left and right sides of doorframe 1 is fixing by gusset piece 10, prevents the doorframe distortion.Can also know from figure and find out and have obvious slit 11 between external door leaf 2 and the exterior door frame 1 that apparent, the door leaf of this kind security door is easily pried open, there is defective in performance of anti-theft door.
Fig. 3 is doorframe of the present utility model and door leaf assembling diagrammatic sketch, as can be seen from the figure, the utility model is that with existing known steel dual-layer antitheft door difference the unlatching edge column surface of exterior door frame 1 is shaped on groove 12, lid tape edge 13 ends of the unlatching limit outer panels of external door leaf 2 are shaped on crotch 14, this crotch 14 is complementary with doorframe column surface groove 12, when shutting external door leaf 2, the crotch 14 that the unlatching limit of external door leaf 2 lid tape edge is shaped on just is embedded in the doorframe column surface groove 12.
