Combined door frame convenient for standardized machining

Abstract

The invention discloses a combined door frame convenient for standardized machining, and aims to provide a combined door frame, which has simple structure and long service life and facilitates standardized machining. The technical key points of the combined door frame are as follows: the door frame includes a metal frame body; the metal frame body includes a metal baseplate fitted with a wall body with door openings; a first connecting board and a second connecting board with mutually parallel upper surfaces are arranged on one side of the metal baseplate; the height difference between the first connecting board and the second connecting board is greater than the height of a stepped part for accommodating door leaves; a front extension part of the metal baseplate and a front vertical plate form a front connecting part; the rear extension part of the metal baseplate and a rear vertical plate form a rear connecting part; the first connecting board is connected with a solid wooden decorative board; the second connecting board is connected with a solid wooden internal cover plate; a front connecting part is connected with a solid wooden external cover plate; a solid wooden connecting board is connected onto the outer side of the solid wooden external cover plate in a plugged manner; a front decorative cover plate is connected onto the outer side of the solid wooden connecting board; a rear connecting part is connected with a rear decorative cover plate. The combined door frame belongs to the technical field of door design.

Description

technical field [0001] The invention discloses a door frame, in particular, a combined door frame which is convenient for standardized processing, and belongs to the technical field of door design. Background technique [0002] The door frame is a frame set on the inner edge of the door hole reserved on the wall for installing and supporting the door. Due to objective reasons such as temperature, the thickness of the walls of buildings in the north and south is different, and the thickness of the walls in the north is generally thicker than that in the south. Therefore, the manufacture of the door frame can only be manufactured in a custom-made manner, which cannot realize industrialized production in large quantities. As a result, a combined door frame that facilitates standardized processing has emerged, using the method of bonding the inner frame and the outer frame. Although this structure is conducive to industrialized large-scale processing, it is also convenient for ...

Problems solved by technology

Therefore, the manufacture of the door frame can only be manufactured in a customized manner, and it is impossible to realize mass industrial production

As a result, a combined door frame that facilitates standardized processing has emerged, using the method of bonding the inner frame and the outer frame. Although this structure is conducive to industrialized large-scale processing, it is also convenient for on-site installation of the door frame. After a while, the glue on the bonding parts of the inner and outer frames is easy to be air-dried, resulting in an unstable connection between the inner and outer frames, and the door frame is deformed and cracked to varying degrees; in addition, the all-solid wood door frame is easily deformed by weather changes, which not only affects the appearance of the door frame , and even affect the sealing performance when the door is closed as a whole, especially after the deformation of the door frame, the position of the lock hole in the door frame and the lock core on the door leaf will change accordingly, making it difficult to lock the door. This user has brought certain troubles, so there is an improved necessary
