Description

A kind of security door structure

Affiliated field

The utility model belongs to security door, refers in particular to a kind of steel security door structure.

Background technology

In these years along with living standard improves, people's theft-proof requirement is more and more higher, the security door manufacturing technology is constantly progressive, the two stratification security doors of steel are antitheft with it, sound insulation, ventilation, advantage such as fire-retardant have progressively replaced existing steel simple gate fan security door, yet, blemish in an otherwise perfect thing be that at present this series products also exists between door leaf and the doorframe gap big, the easy shortcoming of being pried open, influenced the safety of security door, existing procucts (as Fig. 1) are opened the limit with door leaf and are stretched out and cover at doorframe and open on the column surface to reach the pick-proof purpose on the market.But still leave the gap between door leaf hinge edge and the column hinge edge, this mainly contains two aspect reasons: (1) designer does not reckon with the serious consequence that this gap exists, (2) because the existence of hinge, if the door leaf hinge edge also stretches out, then can cause door leaf hindered by the hinge edge column and can't open by general thinking.Yet this will cause the burglar hinge to be destroyed as cutting point in the hinge side by this gap, pry open by this gap Jiang Men again then.

Summary of the invention

The purpose of this utility model provides a kind of security door structure that has more theftproof of having eliminated gap between door leaf hinge edge and the column hinge edge.

The purpose of this utility model is achieved in that a kind of security door structure, is made up of door leaf, hinge edge column, hinge etc., and the door leaf hinge edge stretches out and forms lid seam plate, and the hinge head position is comparatively to outer process.

The utility model is owing to increased lid seam plate, and the gap tegmentum seam plate between hinge edge column and the door leaf hinge edge covers, and the robber can't destroy hinge and then lever up door leaf by this gap, and the security door theftproof performance is strengthened greatly.

The specific embodiment

Now in conjunction with the embodiments accompanying drawing is described in further detail, as shown in Figure 3, a kind of security door structure, form by door leaf (1), hinge edge column (2), hinge (3) etc., the door leaf hinge edge stretches out and forms lid seam plate (11), gap tegmentum seam plate (11) between hinge edge column (2) and the door leaf hinge edge covers, and hinge head (31) position is comparatively to outer process (in conjunction with Fig. 2), so that door leaf (1) can freely rotate and unlikelyly hindered by hinge edge column (2) around hinge (3).In order to increase fastness, hinge edge column face, door leaf hinge edge column stationary plane have increased to reinforce mends plate in addition.

Claims (1)

1, a kind of security door structure is made up of door leaf, hinge edge column, hinge etc., it is characterized in that; The door leaf hinge edge stretches out and forms lid seam plate, and the hinge head position is comparatively to outer process.
