Abstract
The utility model relates to an embedded pry-proof structure for security door, which is characterized in that a pry-proof panel is vertical to a protecting cover plate and arranged on the outer edge of the protecting cover plate on the edge of the security door; a rabbet matched with the pry-proof panel is arranged on a door frame. The utility model has the advantages that the destroyer can not pry and deform the protecting cover plate with crowbar, thereby, after the bolt is forcibly destroyed, and the door leaf is prized out of door frame, the deformation of the panel enables firmer closing of the door leaf when the force is applied by the crowbar, improving the theftproof performance of the security door.
Description
Technical field
The utility model relates to the theft-prevention structure of building doors and windows, a kind of especially embedded pick-proof structure of security door.
Background technology
Existing security door generally constitutes by hollow door leaf 2 of steel and doorframe 1 as shown in Figure 1, and the one side connects with hinge.In order to close tight and safety, generally the edge's (except hinging on one side) at door leaf embedding doorframe is provided with narrow protective cover plate 3, in order to the crack between a door and its frame after fastening between door leaf and doorframe is covered, forms false horizontal false door seam 4 on the door limit.The pick-proof effect of said structure is very little, because the thief can be as shown in Figure 2, inserts between protective cover plates and the doorframe with crowbar 6, cover plate is levered up and shows crack between a door and its frame, and then go deep among the crack between a door and its frame disconnected (bending) dead bolt 5 of sled by force, opens door leaf.This shows that existing security door structure influence the theftproof performance of security door.
Summary of the invention
The purpose of this utility model provides a kind of embedded pick-proof structure of security door, make the thief protective cover plate on door limit be levered up distortion with crowbar class instrument, can't destroy dead bolt by force, and door leaf is prized within the doorframe, thus the theftproof performance of raising security door.
For achieving the above object, the utility model is taked following design scheme: in the protective cover plate outer rim of security door door leaf edge, the pick-proof panel vertical with this cover plate is set, the caulking groove with pick-proof panel coupling is set on doorframe.
The embedded pick-proof structure of this security door, owing to be provided with the pick-proof panel in the protective cover plate outer rim of door leaf, doorframe is provided with the caulking groove with this panel coupling, after door leaf cut out, the pick-proof panel was placed within the caulking groove.Between the protective cover plate of door leaf and doorframe have a crack between a door and its frame by seeing outdoors this moment, but the bottom of this crack between a door and its frame is caulking groove bottom, is a false door seam, and the thief forces open the door and has only from starting with here.
As shown in Figure 5, when the thief inserts the false door seam by force with crowbar 6, because the pick-proof panel 8 that links to each other with the protective cover plate position all places within the caulking groove 7, crowbar firmly also can't make panel deviate from outside the caulking groove in any case, make the protective cover plate distortion, can not expose the crack between a door and its frame that door leaf embeds doorframe, so can't destroy dead bolt to reach the purpose of opening security door by force yet.And when crowbar inserts the false door seam and since powerful pinch shock pick-proof panel counter make panel near and the sidewall of extruding caulking groove, make door leaf combine more firmly with doorframe, door leaf is more difficult to be opened.Thereby the embedded theft-prevention structure of this security door can improve the theftproof performance of security door.

The specific embodiment
Show that as Fig. 3 the utility model is at the protective cover plate 3 outer rim settings of the security door door leaf 2 pick-proof panel 8 vertical with this cover plate, the caulking groove 7 with pick-proof panel coupling is set on doorframe 1; After the door leaf closure, form false door seam 4 between pick-proof panel and the caulking groove 7, and panel 8 embeds in the caulking groove 7 all.Most preferred embodiment of the present utility model is as shown in Figure 4: near on the sidewall of door leaf one side circular arc projection 9 is set at doorframe caulking groove 7 oral areas.Because the effect of this projection, when panel 8 is prized, it tilts to door leaf one side channel wall near bottom land one end, and the projection at notch place can be blocked panel, and it is more difficultly deviate among the caulking groove, has more strengthened this antitheft effect.
