Environment-friendly paint-free welding-free plug-in door frame

Abstract

The invention relates to the technical field of door frames, in particular to an environment-friendly paint-free welding-free plug-in door frame. According to the environment-friendly paint-free welding-free plug-in door frame, vertical braces and cross braces are fixed by clamping clamp strips in clamping grooves and are reinforced through reinforcing ribs, so that the assembled door frame is firmer. A traditional welding and grinding process is replaced through a door frame plug-in process. A traditional paint spraying process is omitted. The production efficiency is greatly improved. The energy-saving and environment-friendly effects are achieved really. Expansion strips and sealing rubber strips are arranged in the positions, making contact with a wall, of inner and outer borders of the door frame correspondingly. During installation of the door frame, the door frame and the wall are firmly sealed through the expansion strips and the sealing rubber strips in a tightly-pressing state. The door frame is good in installation sealing effect and cannot get loose. Magnetic strips and soft rubber strips are arranged in the positions where the door frame and a door body are closed, sothat during door closing, no noise is generated, and the sealing effects between the door frame and the door body is better.

Description

technical field [0001] The invention relates to the technical field of door frames, in particular to an environment-friendly paint-free and solder-free plug-in door frame. Background technique [0002] Traditional doorframes are mostly made of metal, especially the doorframes of community units. The processing process requires cutting boards → bending machine bending → splicing frames → manual welding → grinding → painting and other processes to make finished products; after welding, grinding and painting The poisonous gas produced in the process is directly discharged to the outside, which not only causes certain harm to the workers' bodies, but also pollutes the environment. Therefore, poisonous gas is the key object to be dealt with in the production process.

AI Technical Summary

Problems solved by technology

[0003] When the traditional door frame is installed, the outer frame is directly buckled and pressed on the outer wall, and the inner frame is fixed on the wall by wrapping corners, and plays a certain decorative role, but its welding position, the connection position of the inner and outer frames and the wall, and the door There is a certain gap between them, resulting in poor sealing and heat preservation effect of the door frame; due to the poor sealing effect of the door frame, noise often occurs when the outside natural wind enters the house

[0004] In order to ensure the sealing, the outer seam of the door frame and the wall is generally coated with sealant. When used for a long time, the vibration generated when the door is opened and closed will cause the sealant to fall off, the sealing effect of the door frame will decrease, and the door frame will shake in severe cases.
