Abstract

The utility model relates to a high-strength structural door frame, which comprises a door leaf frame (1), a long frame (2) and a short frame (3); the door leaf frame (1), the long frame (2) and the short frame (3) are of an integrated structure formed by bending plates; a bending bulge (101) for limiting the door is arranged on the door leaf frame (1), and a bending groove (102) for buffering impact is arranged at the joint of the bending bulge (101) and the door leaf frame (1); the long frame (2) is also provided with a bending groove (202) for buffering the impact of the fixing screw; the bending groove (102) and the bending groove (202) respectively play a role in buffering collision impact on the door leaf frame (1) and the long frame (2), and the impact resistance of the door frame structure is improved.

Description

High-strength structural door frame

Technical Field

The utility model relates to a door and window makes the field, especially a high strength structure door frame.

Background

The door frame is the structure with the door complex, and only after door frame and wall body fixed connection, the installation and the use that the door just can be steady. The common door frame is a wooden door frame made of square timber and a metal door frame made of metal plates bent into a channel steel shape; the wooden door and the wooden door frame have weak damage-proof capability and the shelf life is greatly influenced by the environment, for example, in rural areas, the wooden door is easy to decay and deform integrally under the action of rain and dew, so the wooden door is mainly used as an inner door and is arranged indoors, and the metal door frame thereof have strong damage-proof capability and cannot decay and deform integrally and are mainly used as a safety door and a fireproof door. The connection mode of door frame and wall body is screw connection, but metal door frame compares with the timber door frame, and timber door frame and screw connection are compacter and firm, consequently, the connection of metal door frame and wall body does not have the timber door frame firm. When the metal door frame is impacted by the door closing, the impact on the screw is greater, and local small deformation of the metal structure is more likely to occur. Compared with a wooden door frame, the metal door frame is more complex in structure and more in manufacturing process, so that the metal door frame is generally of a hollow structure and is formed by combining a plurality of parts, and therefore the installation procedure is complex and the installation efficiency is low.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to overcome prior art's shortcoming, provide an installation fast and have buffer capacity's high strength structure door frame.

The purpose of the utility model is realized through the following technical scheme: a high-strength structural door frame comprises a door leaf frame, a long frame and a short frame; the door leaf frame, the long frame and the short frame are of an integrated structure formed by bending plates, and the integrated structure is further provided with a plurality of bending grooves used for buffering impact.

The door frame is provided with a bending bulge for limiting the door, and a first bending groove for buffering impact is formed in the joint of the bending bulge and the door frame.

The corners of the long frame and the door leaf frame are processed into arc surfaces.

And a second bending groove for buffering impact is further arranged on the long frame.

The utility model has the advantages of it is following:

1. compared with other combined structures, the integrated bending structure reduces the installation steps, reduces the installation difficulty and accelerates the installation efficiency;

2. the door frame is provided with a bending groove for buffering impact, so that the door frame can bear larger impact without damage.

Drawings

Fig. 1 is a schematic structural view of the present invention;

FIG. 2 is a cross-sectional view taken at A-A of FIG. 1;

in the figure: 1-a door leaf frame, 2-a long frame, 3-a short frame, 101-a bending bulge, 102-a first bending groove, 201-an arc surface and 202-a second bending groove.

Detailed Description

The invention will be further described with reference to the accompanying drawings, but the scope of the invention is not limited to the following description.

As shown in fig. 1, a high strength structural door frame includes a door leaf frame 1, a long frame 2 and a short frame 3; the door leaf frame 1, the long frame 2 and the short frame 3 are of an integrated structure formed by bending plates, and the integrated structure is further provided with a plurality of bending grooves used for buffering impact.

The door frame 1 is provided with a bending protrusion 101 for limiting the door, and a first bending groove 102 for buffering impact is arranged at the joint of the bending protrusion 101 and the door frame 1.

The corner of the long frame 2 and the door leaf frame 1 is processed into an arc surface 201.

And a second bending groove 202 for buffering the impact of the fixing screw is further arranged on the long frame 2.

The door can collide the bending bulge 101 when being closed, and the bending bulge 101 can prevent the door frame and the hinge from being twisted due to the overlarge swinging angle of the door, so that the door frame and the hinge are deformed. The bending protrusion 101 can also deform under the collision of the door, but the bending protrusion 101 is connected with the first bending groove 102, the bending protrusion 101 can pull the first bending groove 102 when deforming, the connection inclined plane of the first bending groove 102 and the door leaf frame 1 can be straightened, and the bending protrusion 101 deforms under the condition that the deformation size exceeds the maximum elastic deformation, the first bending groove 102 can deform simultaneously when the bending protrusion 101 deforms, so only the deformation size of the bending protrusion 101 exceeds the sum of the maximum elastic deformation of the bending protrusion 101 and the maximum elastic deformation of the first bending groove 102, and the outer frame 2 can play a role in buffering when being collided by an external person or object similarly.
