Welding-free double-side-covered flower type door frame

Abstract

A welding-free double-side-covered flower type door frame is formed by combining a left frame, a left small-flower type frame, a right frame, a right small-flower type frame, an upper frame, an upper small-flower type frame and a lower frame, wherein clamping pieces of relevant parts are correspondingly inserted into clamping holes formed in other parts during combination. The welding-free double-side-covered flower type door frame is attractive in appearance and can simultaneously cover the two sides of a wall in application, the bending times are increased, and the overall strength and firmness of the door frame are obviously improved. The anti-rusting and corrosion-resisting functions of the door frame can be also obviously improved. Before the door frame is used, several parts can be transported to a destination and then are assembled into the whole formed door frame instead of the mode that the door frame is welded into a formed assembly. Due to the fact that the several parts are smaller in size and light in weight, the parts are convenient and easy to carry, the carriage capacity of a transporting vehicle can be more than two times of the carriage capacity of the formed door frame through layout and pileup in the pileup process, and the transporting cost is remarkably reduced.

Description

technical field [0001] The invention belongs to a door frame, in particular to a welding-free double-wrapped door frame. Background technique [0002] The traditional steel door frame cannot cover the wall on both sides of the wall at the same time, and can only cover the wall on one side. After the door frame is installed on the wall, there are still many exposed walls, which is uncoordinated and unsightly in appearance. And the firmness of the door frame is just poor. After the wall is corroded, the door frame is easy to rust, which in turn affects the appearance and quality of the door. At the same time, the traditional door frame is a short integral structure formed by welding, which requires special welding equipment and professional welders in the preparation process. Therefore, the manufacturing process of the traditional steel door frame is not only cumbersome, but also consumes a lot of energy, and the production cost is also virtually increased. A door frame of...

Problems solved by technology

[0002] The traditional steel door frame cannot cover the wall on both sides of the wall at the same time, it can only cover the wall on one side

After the door frame is installed on the wall, there are still a lot of exposed walls, which is uncoordinated and unsightly in appearance

Moreover, the firmness of the door frame is poor.

After the wall is corroded, the door frame is easy to rust, which in turn affects the appearance and quality of the door

At the same time, the traditional door frame is a short integral structure through welding, which requires special welding equipment and professional welders during the preparation process.

Therefore, the production process of the traditional steel door frame is not only cumbersome, but also consumes a lot of energy, and the production cost is also virtually increased.

A door frame with integral structure is also inconvenient in terms of transportation
