Abstract

The utility model provides a hinge connecting plate structure for protecting a metal door body against deformation, which comprises a door body and a hinge. A structure in double-n shape is adopted for two sides of the door body, and a caulking groove is formed on the two sides of the door body; and a fixed plate is fixed in the caulking groove, the fixed plate is connected with a connecting plate, and the hinge is connected on the connecting plate. The hinge connecting plate structure adopts a split type structure; and when an external force is applied to the door body, the connecting plate can deform so as to protect the door body and a door frame against the deformation. A double-n shape design is adopted for the sides of door body, so as to achieve that the integrated intensity of a door leaf is greatly increased and the intensity of the door leaf is larger than that of a hinge structure.

Description

A kind of metal door body anti-deformation hinge junction plate structure

Technical field

The utility model relates to a kind of metal door body structure, particularly a kind of metal door body anti-deformation hinge junction plate structure.

Background technology

Mainly it comprises security door to metal door, anti-forcing open the door, building security door, decorative art door, labeled door etc., all need being connected of door leaf and doorframe to hinge or the concealed installation hinge connects with bright, to realize the rotation of door leaf on doorframe, finish and open the door, close an action, this series products of seeing in the market all adopts door leaf inside, hinge edge surface local welding small size stiffener, single punch then, tapping is installed to door hinge above the door leaf after outward appearance is sprayed paint, and works as door leaf like this and is subjected to external force, as strong wind, during the extruding of foreign matter, tend to be linked to be the hinge connection gross distortion of door leaf, even snap and tear, door leaf can't be repaired or normally use, especially at the building door, fire metal door, metal finishing art and craft doors etc. are above the commons door, and this type of problem is even more serious.

At the problems referred to above, I have designed a kind of split type detachable metal door hinge junction plate structure that adopts, and adopt the design of two " n " types.

The utility model content

The purpose of this utility model provides a kind of metal door body anti-deformation hinge junction plate structure, can prevent that door leaf from producing distortion or damage when being subjected to strong external force.

A kind of metal door body anti-deformation hinge junction plate structure comprises a body and hinge, and the side of door body adopts two " n " type structures, and forms caulking groove; Be fixed with fixed head in the caulking groove, fixed head is connected with junction plate, and described hinge is connected on the junction plate.

Adopt split type structure, when the door body was subjected to external force, junction plate can deform, thereby shutter body, doorframe are indeformable.Two " n " shape designs are adopted on door limit, side, and the door leaf bulk strength is strengthened greatly, and its intensity is higher than the intensity of hinge arrangement.

Description of drawings

With embodiment the utility model is described in further detail with reference to the accompanying drawings below.

Fig. 1 is a system construction drawing of the present utility model;

Fig. 2 is an A-A schematic cross-section among Fig. 1;

Fig. 3 is a B-B schematic cross-section among Fig. 1.

The specific embodiment

As Figure 1-3, metal door body anti-deformation hinge junction plate structure described in the utility model comprises a body 1 and hinge 2, and hinge 2 is fixed on the doorframe, and the side of door body 1 adopts two " n " type structures, and is welded together to form caulking groove; Be welded with fixed head 3 in the caulking groove, fixed head 3 is connected with junction plate 4, and described hinge 2 is connected on the junction plate 4, and junction plate 4 interior welds have stiffener 5.

Claims

1, a kind of metal door body anti-deformation hinge junction plate structure comprises a body and hinge, it is characterized in that, the side of door body adopts two " n " type structures, and forms caulking groove; Be fixed with fixed head in the caulking groove, fixed head is connected with junction plate, and described hinge is connected on the junction plate.
