Door frame with adjustable thickness

Abstract

The invention relates to a door frame with adjustable thickness. The door frame includes an n-shaped door frame body, and the door frame body is composed of an upper door frame and two side door frames; the upper door frame and the side door frames of the door frame body are separately composed of fixing plates of the same structure, adjustable plates of the same structure and adjustment guide assemblies of the same structure; the upper right sides of the fixing plates are matched with the left sides of adjustable plates and are connected together through the multiple adjustment guide assemblies; the adjustment guide assemblies are each composed of two bent sheet metal parts of the same structure, one of every two bent sheet metal parts is fixedly connected to the corresponding fixing plate, and the other one of every two bent sheet metal parts is fixedly connected to the corresponding adjustable plates; and the end parts of every two bent sheet metal parts are relatively matched and can slide. According to the door frame with the adjustable thickness, the thickness of the door frame can be adjusted on an installation site to be matched with the thickness of a wall body on the site, the smooth installation of the door frame can be ensured, and the production batches of enterprises can be reduced.

Description

technical field [0001] The invention relates to a house door and window, in particular to a door frame with adjustable thickness. Background technique [0002] At present, most steel door frames on the market are only suitable for a single wall thickness during installation, that is, one door frame matches one wall thickness. However, when the door frame is installed, it often happens that the door frame does not match the thickness of the wall. Some need to be equipped with a 15 cm thick door frame, and some need to be equipped with a 20 cm thick door frame, etc. Once the wall thickness changes, It cannot be installed directly. Due to the lack of thickness adjustment function, it cannot be adjusted at the installation site, which makes it difficult to install the door frame. It is difficult to change the thickness of the wall, so we can only choose a door frame suitable for the thickness of the wall. As a result, there are many production batches in the enterprise, which...

[0002] At present, most steel door frames on the market are only suitable for a single wall thickness during installation, that is, one door frame matches one wall thickness

However, when the door frame is installed, it often happens that the door frame does not match the thickness of the wall. Some need to be equipped with a 15 cm thick door frame, and some need to be equipped with a 20 cm thick door frame, etc. Once the wall thickness changes, cannot be installed directly

Due to the lack of thickness adjustment function, it cannot be adjusted at the installation site, making it difficult to install the door frame

It is difficult to change the thickness of the wall, so we can only choose a door frame suitable for the thickness of the wall

As a result, there are many production batches in the enterprise, which is not conducive to mass production
